Myelopathy due to calcification of the cervical ligamenta flava: a report of two cases in West Indian patients. (1/67)

Two cases of cervical myelopathy due to calcification of the ligamenta flava (CLF) are described for the first time in black patients from the French West Indies. A pre-operative CT scan differentiated the diagnosis from one of ossification of the ligamenta flava. Microanalysis on the operatively excised specimen in one patient revealed a mixture of calcium pyrophosphate dihydrate crystals and hydroxypatite crystals. Poor outcome in one patient contrasting with excellent recovery in the other one, who had undergone posterior decompressive laminectomy, emphasizes the importance of surgery in the management of CLF.  (+info)

MR imaging of a hemorrhagic and granulomatous cyst of the ligamentum flavum with pathologic correlation. (2/67)

Cysts of the ligamentum flavum are uncommon causes of neurologic signs and symptoms and usually are seen in persons over 50 years of age. We report a case of an epidural cyst located in the ligamentum flavum, which contributed to spinal stenosis in a 30-year-old man. Radiologic features were similar to those of a synovial cyst, but synovium was not identified histologically. The imaging and pathologic features were unusual, including hemorrhage and a fibrohistiocytic reaction with giant cells.  (+info)

Histology of the ligamentum flavum in patients with degenerative lumbar spinal stenosis. (3/67)

The degree of calcification as well as the structural changes of the elastic fibres in the ligamentum flavum in patients with degenerative lumbar spinal stenosis were evaluated and the results were compared to those of patients without spinal stenosis. In 21 patients (13 male, 8 female) with lumbar spinal stenosis the ligamentum flavum was removed, histologically processed and stained. The calcification, the elastic/collagenous fibre ratio as well as the configuration of the fibres were evaluated with an image analyzing computer. As a control group, 20 ligaments of 10 human corpses were processed in the same way. The results were statistically analysed using the Mann-Whitney-Wilcoxon test (alpha = 0.05) and the t-test (alpha = 0.05). Nearly all the ligaments of patients with lumbar spinal stenosis were calcified (average 0.17%, maximum 3.8%) and showed relevant fibrosis with decreased elastic/collagenous fibre ratio. There was a significant correlation between age and histological changes (P<0.05). In the control group we only found minimal calcification in 3 of 20 segments (average 0.015%). No relevant fibrosis was found and the configuration of elastic fibres showed no pathologic changes. The results of this study illustrate the important role of histological changes of the ligamentum flavum for the aetiology of lumbar spinal stenosis.  (+info)

Calcification of the cervical ligamentum flavum--case report. (4/67)

A 52-year-old male presented with calcification of the cervical ligamentum flavum manifesting as hypesthesia of the bilateral middle, ring, and little fingers and ulnar halves of both forearms, as well as motor weakness in the bilateral upper extremities and gait disturbance. Cervical x-ray tomography detected a round calcified mass on the posterior wall of the cervical canal at the C-5 level. Computed tomography showed the round, nodular calcified mass more clearly. Magnetic resonance imaging showed an epidural low intensity mass compressing and distorting the cervical cord at the C-5 level on both T1- and T2-weighted images. Administration of gadolinium-diethylenetriaminepenta-acetic acid caused marginal enhancement of the mass. The lesion was eventually removed by posterior laminectomy. The mass was composed of a very hard crystal-like calcified deposition in the ligamentum flavum. X-ray diffraction analysis of the histological specimen showed calcium pyrophosphate dihydrate (CPPD) and hydroxyapatite in the crystal-like substance, confirming that CPPD is responsible for calcification of the cervical ligamentum flavum.  (+info)

Spinal cord and cauda equina compression in 'DISH'. (5/67)

Diffuse idiopathic skeletal hyperostosis (DISH) has long been regarded as a benign asymptomatic clinical entity with an innocuous clinical course. Precise information is lacking in the world literature. Authors report the results of a retrospective analysis of 74 cases of DISH. Eleven patients presented with progressive spinal cord or cauda equina compression. In nine cases ossified posterior longitudinal ligament (OPLL) and in two cases ossified ligamentum flavum (OLF) were primarily responsible. Surgically treated patients (eight) had far better outcome as compared to the patients managed conservatively, as they had refused surgery. 'DISH' is neither a benign condition, nor it always runs a innocuous clinical course. In fact, in about 15% of the cases, serious neurological manifestations occur, which may require a major neurosurgical intervention.  (+info)

Activation and localization of cartilage-derived morphogenetic protein-1 at the site of ossification of the ligamentum flavum. (6/67)

Localization and expression of cartilage-derived morphogenetic protein (CDMP)-1 in tissues at the site of ossification of the ligamentum flavum (OLF) were examined by immunohistochemistry and in situ hybridization. The CDMP-1 protein and messenger ribonucleic acid (mRNA) were localized in spindle-shaped cells and chondrocytes in the OLF tissues. CDMP-1 was not detected in cells in non-ossified sites. These data indicate that CDMP-1 is locally activated and localized in spindle-shaped cells and chondrocytes at the site of OLE. Given the previously reported promoting action of CDMP-1 for chondrogenesis, the current results suggest that CDMP-1 may be involved in the progression of OLF, leading to the narrowing of spinal canal and thus causing severe clinical manifestations.  (+info)

The lumbar epidural space in pregnancy: visualization by ultrasonography. (7/67)

Epidural anaesthesia is an important analgesia technique for obstetric delivery. During pregnancy, however, obesity and oedema frequently obscure anatomical landmarks. Using ultrasonography, we investigated the influence of these changes on spinal and epidural anatomy. We examined 53 pregnant women who were to receive epidural block for vaginal delivery or Caesarean section. The first ultrasound imaging was performed immediately before epidural puncture; the follow-up scan was done 9 months later. The ultrasound scan of the spinal column was performed at the L3/4 interspace in transverse and longitudinal planes, using a Sonoace 6000 ultrasonograph (Kretz, Marl, Germany) equipped with a 5.0-MHz curved array probe. We measured two distances from the skin to the epidural space: the minimum (perpendicular) and the maximum (oblique) needle trajectory. The quality of ultrasonic depiction was analysed by a numerical scoring system. An average weight reduction of 12.5 kg had occurred by the follow-up examination. During pregnancy, the optimum puncture site available on the skin for epidural space cannulation was smaller, the soft-tissue channel between the spinal processes was narrower, and the skin-epidural space distance was greater. The epidural space was narrower and deformed by the tissue changes. The visibility of the ligamentum flavum, of the dura mater and of the epidural space decreased significantly during pregnancy. Nevertheless, ultrasonography offered useful pre-puncture information. Thus far, palpation has been the only available technique to facilitate epidural puncture. Ultrasound imaging enabled us to assess the structures to be perforated. We anticipate that this technique will become valuable clinically.  (+info)

Thoracic cord compression due to ossified hypertrophied ligamentum flavum. (8/67)

Ossified ligamentum flavum is increasingly appreciated as an important cause of thoracic myeloradiculopathy. Fifteen patients with age ranging from 30-61 years were studied. Fourteen presented with spastic paraparesis, and radiculopathy was the only complaint in one patient. Routine skiagrams and myelograms showed non-specific changes. Baseline CT and CT myelogram, however, documented the ossification of ligamentum flavum comprehensively. MRI was done in three patients. Multiple levels of the disease were seen in two cases. Four patients had ossified posterior longitudinal ligament. Thickened ligamentum flavum should be considered as an important cause of thoracic cord compression.  (+info)

Mechanical load-induced osteogenic differentiation might be the key cellular event in the calcification and ossification of ligamentum flavum. The aim of this study was to investigate the influence of tissue transglutaminase (TGM2) on mechanical load-induced osteogenesis of ligamentum flavum cells. Human ligamentum flavum cells were obtained from 12 patients undergoing lumbar spine surgery. Osteogenic phenotypes of ligamentum flavum cells, such as alkaline phosphatase (ALP), Alizarin red-S stain, and gene expression of osteogenic makers were evaluated following the administration of mechanical load and BMP-2 treatment. The expression of TGM2 was evaluated by real-time PCR, Western blotting, and enzyme-linked immunosorbent assay (ELISA) analysis. Our results showed that mechanical load in combination with BMP-2 enhanced calcium deposition and ALP activity. Mechanical load significantly increased ALP and OC gene expression on day 3, whereas BMP-2 significantly increased ALP, OPN, and Run

Ligamentum flavum in the cervical region is thin or not fused at the midline. The distinct elastic resistance offered by the ligamentum flavum before entering the epidural space when using the loss of resistance (LOR) technique may be blunted or even absent. The investigators inferred that the size and elasticity of the ligamentum flavum, in combination with mildline appraoch, the gaps could be responsible for a failure to recognize a LOR in some patients. If so, the investigators hypothesized that the paramedian approach would be advantageous for finding cervical epidural space more easily during cervical epidural steroid injections (CESIs). Therefore, the investigators randomly divide our patients into 2 groups; the midline approach group and the paramedian group. Then, the investigators examine the patterns of the pressure changes at the moment of a puncture of the ligamentum flavum during CESIs ...

Background Minimally invasive laminectomy is a very effective surgical method for treating lumbar stenosis. However, this technique can be technically difficult, especially in patients suffering from severe stenosis. The contralateral decompression from a unilateral approach can result in durotomy during removal of the hypertrophied ligamentum flavum. This complication can be difficult to treat through a small working channel. Objective To detail our groups operative experience with the CO2 laser and discuss our results and previous studies in the literature reporting results. Methods The CO2 laser (Omniguide, Boston, MA) was investigated in the surgical ablation of the contralateral ligamentum flavum during minimally invasive laminectomies. Forty levels have been investigated thus far. The amount of voltage needed to adequately desiccate and remove the ligamentum flavum safely as well as the effectiveness of this technique were investigated. Results The contralateral ligamentum flavum could be ...
STUDY DESIGN Retrospective cross-sectional study. PURPOSE To investigate the relationship between ligamentum flavum (LF) hypertrophy and lumbar segmental motion. OVERVIEW OF LITERATURE The pathogenesis of LF thickening is unclear and whether the thickening results from tissue hypertrophy or buckling remains controversial. METHODS 296 consecutive patients underwent assessment of the lumbar spine by radiographic and magnetic resonance imaging (MRI). Of these patients, 39 with normal L4-L5 disc height were selected to exclude LF buckling as one component of LF hypertrophy. The study group included 27 men and 12 women, with an average age of 61.2 years (range, 23-81 years). Disc degeneration and LF thickness were quantified on MRI. Lumbar segmental spine instability and presence of a vacuum phenomenon were identified on radiographic images. RESULTS The distribution of disc degeneration and LF thickness included grade II degeneration in 4 patients, with a mean LF thickness of 2.43±0.20 mm; grade III

Elastin degradation and fibrosis of the ligamentum flavum were significantly more severe in the spinal stenosis samples than that in the disc herniation samples (3.14 +/- 0.50 vs. 0.55 +/- 0.60, p < 0.001; 3.10 +/- 0.57 vs. 0.76 +/- 0.52, p < 0.001, respectively). The expressions of the active form of MMPs were identified in all the ligamentum flavums of the spinal stenosis and disc herniation patients. The expressions of active MMP-2 and MMP-13 were significantly higher in the spinal stenosis samples than that in the disc herniation samples (both p < 0.05). The expression of active MMP-3 was slightly higher in the spinal stenosis samples than that in the disc herniation samples, but the difference was not statistically significant (p = 0.131). MMP-2, -3, and -13 were positively stained on the ligamentum flavum fibroblasts ...

On examination, he had a left-sided partial foot drop (extensor hallucis longus dorsiflexion 3/5) and sacral hypoesthesia. The magnetic resonance (MR) imaging showed severe L4-L5 stenosis, and two lumbar cysts: cyst I was located in the left foramen, while Cyst II was situated between the dura and ligamentum flavum; there was no evidence of instability [Figures 1 and 2]. A transforaminal endoscopic approach revealed that cyst I was attached to the left facet joint; indeed, it proved to be a synovial cyst [Figure 3]. A full endoscopic interlaminar approach was utilized to excise cyst II; this huge epidural cyst with marked adhesions was not connected to either the ligamentum flavum or the dura [Figure 4].

Once consent has been obtained from the patient, the patient is laid in a face down position and administered general anaesthetic. The area of the back where the disc is herniated is cleaned with antiseptic solution. A tiny incision is made just next to the midline of the back.. Through this incision, the surgeon passes a dilator which creates a path that leads to the spinal canal. The dilator is advanced all the way to the level of the ligamentum flavum which is a protective covering that covers the back of the spinal-cord. A cannula is advanced along the dilator and once the cannula is in position, the dilator is removed. Through this cannula, the surgeon passes an endoscope which allows him or her to visualise the structures. Instruments may be passed along the endoscope to puncture the ligamentum flavum and if necessary the intervening spinal bone. Once access is obtained to the spinal canal, the nerve fiber are gently moved to the side so that the herniated disc can be visualized. With the ...

Our review demonstrates that complication profiles are similar for tubular microdiscectomy compared with the standard open technique. Intraoperative dural tear is the most common complication; rates range from 7%-10%.4,13,20,22,29 There are several technical nuances to avoid this frequent complication. First, once the tubular retractor is docked in the appropriate location, complete bone removal with the drill and rongeurs should be performed using the entire operative field within the tube. This bone decompression relieves some of the stenosis, allowing for free passage of instruments adjacent to the dura. A ball dissector should be passed under the ligamentum flavum prior to flavectomy to eliminate tethering adhesions, which could otherwise lead to durotomy. While removing the ligamentum flavum, the use of angled Kerrison rongeurs can avoid inadvertent entry of the dura into the jaws of the instrument. We prefer to use the 90° rongeur when progressing medially and inferiorly, while using the ...
The patient should be sitting or lying on their side. Back flexion opens the intervertebral spaces. The back is cleaned using standard antiseptic solution. The anaesthetist should adopt an aseptic technique. Aim to identify the L3/4, L4/5 or L5/S1 interspace (use Tuffiers line). The chosen interspace is infiltrated with local anaesthetic. The spinal needle is inserted in the midline, aiming slightly cranially. Resistance increases as the ligamentum flavum is entered and when the dura is encountered, with a sudden give as the dura is pierced. Correct placement of the needle is confirmed by cerebrospinal fluid at the hub.. The paramedian approach requires less back flexion (may be limited in certain patients). Infiltrate with local anaesthetic 1.5 cm lateral to the cranial border of the spinous process at the interspace. Aim the needle medially and cranially until the resistance of the ligamentum flavum is felt. If the lamina is engaged, walk the needle off its cranial edge.. ...

Giant cell tumor of the tendon sheath (GCTTS) occurs most often in the hand and rarely in the feet, and as an extremely uncommon presentation in the knee joint. Case reports involving GCTTS in the knee joint generally describe it originating from the nearby anterior cruciate ligament, posterior cruciate ligament, patellar tendon, and medial plica. To the best of our knowledge, there are no previously reported case reports involving GCTTS originating in the ligamentum mucosum. In this article, we describe a 27-year-old male patient who was admitted to the orthopedic emergency room with a painful locked knee. He had severe pain that was worse with activity and a decreased range of motion. Magnetic resonance imaging (MRI) indicated massive swelling and a well- circumscribed lobulated intraarticular mass at the distal one third of the ligamentum mucosum. The mass was removed successfully with arthroscopic-assisted mini-open excision, and histological analysis subsequently diagnosed it as a localized ...

In this prospective study, the authors evaluated data from 44 patients (23 male and 21 female) who underwent posterior decompression and fusion surgery with instrumentation for the treatment of T-OPLL at our hospital. The patients mean age at surgery was 50.7 years (range 38-68 years). The minimum duration of follow-up was 2 years. The location of thoracic ossification of the ligamentum flavum (T-OLF), T-OLF at the OPLL level, OPLL morphology, fusion range, estimated blood loss, operative time, pre- and postoperative Japanese Orthopaedic Association (JOA) scores, and JOA recovery rate were investigated. Reconstructed sagittal multislice CT images were obtained before and at 3 and 6 months and 1 and 2 years after surgery. The basic fusion area was 3 vertebrae above and below the OPLL lesion. All parameters were compared between patients with and without continuity across the disc space at the OPLL at 3 and 6 months after surgery. ...

This paper outlines an approach to create stereoscopic 3D computer graphics for visualization of epidural insertions. The graphics are built from several 3D vertex models of the anatomical structures including the vertebrae, tissue layers and the skin, subcutaneous fat, supraspinous ligament, interspinous ligament, ligamentum flavum and epidural space. The 3D models are wrapped with full color textures and vertex edges are rounded. The objects are stored in object files and are rendered as 3D by a custom OpenGL application. Graphics drivers calculate the angles and offset for the two separate stereo images and render both in 3D. The stereoscopic images are viewed through a visor containing two OLED micro-displays in stereo using the page-flipped method. The completed stereo simulation allows depth to be perceived so that the operator can judge depth of the needle tip in relation to tissue layers and bones, which aids to the location of the epidural space. Applying stereoscopic vision to epidural ...

Compression of the spinal cord in the cervical spine that results in motor and sensory dysfunction affecting the upper extremities is known as cervical myelopathy. Sometimes a severe compression of the spinal cord at the cervical region can also cause motor and sensory deficient in the lower extremities and disrupt the bowel and bladder function. Degenerative changes in the cervical spine can cause severe cervical myelopathy. There are a few causes that lead to compression of the spinal cord in the cervical region. Narrowing of the spinal canal where the spinal cord is located due to degenerative processes or congenital causes can cause cervical myelopathy. Ossification of the posterior longitudinal ligament or calcification of the ligamentum flavum can result in spinal cord compression. Posterior bony osteophytes arising from the vertebral bodies and uncinated processes can cause narrowing of the spinal canal. Disc herniation or slip disc in the neck is another common cause for cervical ...
FORENSIC TEXTBOOK SCIENCE. A subluxation is a partial dislocation of articulating surfaces of joints, distinct from luxation, which is a complete dislocation. When a vertebra has been subluxated, ligaments, muscles and other structure in close and delicate association with the vertebra move.1 Thus, a point in time arose when direct trauma to the spine had occurred from a foreign object or a fall on the spine. For example, if the fifth vertebra thoracic has been subluxated (joint dynamics have been altered) by trauma or other causes one or more ligaments associated with it will be stretched! Articular capsules, ligamentum flavum, supraspinous and intertransverse ligaments are usually the first ones to develop tension by rotation lateral flexion-rotation of the vertebra. Interspinous, anterior and posterior longitudinal ligaments also are involved. If the tension of ligaments reaches a certain threshold, pressure stimuli will stimulate receptors associated with the ligaments. From the receptor the ...
Spinal stenosis is a narrowing of the spaces in the spine that results in pressure being placed on the spinal cord and/or nerve roots. Although stenosis can develop without symptoms, it may produce numbness, tingling, pain and difficulty in walking, as well as a heavy/tired feeling in the legs. It is estimated that 250,000 to 500,000 Americans currently have symptoms of spinal stenosis.. Skeletal fluorosis is one cause of stenosis. In the advanced stages of fluorosis, the spine may develop extensive ligament calcifications and bony spurs (resembling spondylosis) which can press up against the spinal cord. Among patients with skeletal fluorosis, the cervical region of the spine is the most common site for cord compression. Fluoride-induced stenosis has been reported in the thoracic region as well. In thoracic cases, the spine can be compressed as a result of OLF (ossification of ligamentum flavum). Recent research from China has found that patients with OLF had significantly elevated levels of ...

Microsurgical lumbar laminoplasty is a minimally invasive technique for decompressing pinched nerves in the lumbar spine. Pinched or compressed nerves may result from herniated discs, lumbar spinal stenosis, or spondylolisthesis. The traditional technique for decompression of lumbar nerves is laminectomy, a surgical procedure developed in the early 1900s. In laminectomy, the paraspinal muscles are dissected off the spine bilaterally, that is on the left and right sides of the spinal column. The lamina and spinous process are then removed to gain access to the nerves contained within the spinal canal. The structures that are compressing the nerves (usually ligamentum flavum and herniated disc) are then trimmed until the nerves are free from compression. Laminectomy is an effective procedure for relieving pressure on spinal nerves, but during the procedure, many spinal stabilizing structures are destroyed even though they are not directly compressing the nerves (lamina, spinous process, ...
The operations were performed in 16 patients who diagnosed with spinal stenosis. All individuals had been presented with low-back pain, neurogenic claudication or radiculopathy and unresponsive to conservative treatment over six months. We perfomed hemi-laminectomy at the appropriate levels on the most symptomatic side preserving the facet joint. And the ligamentum flavum, as well as the cortical bone on the ventral surface of the contralateral laminae were removed. The spinous process was left as possible as we can, and the contralateral side of the spinal canal was decompressed completely ...
In the spine, the vertebrae may develop arthritis, the intervertebral discs may bulge, and the ligamentum flavum (a strong ligament that connects the liminae of the vertebrae) may buckle. Patients who are affected by spinal stenosis will experience pain because of the extra pressure put on spinal cord by the spinal column. This compression can […]
Diagnosis of FBSS is made with contrast enhanced MR imaging of the lumbar spine. Canal stenosis is manifest on MR imaging by a trefoil appearance of the spinal canal with a thickened ligamentum flavum. Enhancing nerve roots may be present on contrast enhanced imaging. Vertebral body instability can be diagnosed on flexion and extension views on plain radiographs by demonstrating a dynamic slip of greater than 3 millimeters. MR findings of instability include antero- or retrolisthesis or loss of disc height with loss of disc signal on T2 weighted images. Epidural fibrosis appears low in signal on T1 weighted images with slightly higher signal than disc on T2 images with diffuse contrast enhancement. This is in contrast to herniated disc material which demonstrates little or thin peripheral enhancement after contrast administration. Post-operative arachnoiditis appears on MR imaging as peripheral or central clumping of nerve roots with variable enhancement ...
Dogliottis principle is a principle in epidural anaesthesia first described by Professor Achille Mario Dogliotti in 1933. It is a method for the identification of the epidural space, a potential space. As a needle is advanced through the ligamentum flavum, to the epidural space, with constant pressure applied to the piston of a syringe, loss of resistance occurs once the needle enters the epidural space due to the change in pressure. The identification of this space, allows subsequent administration of epidural anaesthesia, a technique used primarily for analgesia during childbirth. This technique remains in use at present[update], and is commonly referred to the loss of resistance to saline technique (LORS) or its variation, the loss of resistance to air technique (LORA). These use, respectively, saline or air to identify the epidural space. The LORS technique is generally favoured due to the increased complication risk with the LORA technique such as pneumocephalus or air embolism. Epidural ...

Calcification and ossification affect a variety of posterior spinal ligaments and tissues. Ossification of the posterior longitudinal ligament is a characteristic disorder of the spine that may be associated with significant neurologic findings. Its radiographic appearance is diagnostic and consists of a linear band of ossification along the posterior margin of the vertebral bodies and intervertebral discs, particularly in the cervical spine. Arachnoiditis ossificans is a rare condition that leads to extensive ossification in the arachnoid membrane, especially in the thoracic spine, and it produces significant symptoms and signs. Osseous proliferation at the cephalad and caudad attachments of the ligamentum flavum is a frequent finding that is generally of no significance. When extensive, however, such ossification in the thoracic spine leads to neurologic manifestations and is accompanied by involvement of nearby tissues and ligaments and, in some cases, diffuse idiopathic skeletal ...

RV80 - Id hesitate to say that anything in the Netherlands is not as advanced as in LA. Laminoplasties have been around quite a while, though. I believe they may have really started in Japan, perhaps because of a hereditary tendency toward ossification of the ligamentum flavum, which is treated by posterior decompression in the form of laminectomies. They found themselves doing a lot of decompression, perhaps followed a few years later by posterior fusions because of instability resulting from the laminectomies. So they developed the laminoplasty to get around that. The procedure moved eastward from there, hitting Guam in 1996, Hawaii in 2002, and So Cal in 2005.

INTRODUCTION. Degenerative Lumbosacral Stenosis (DLSS) is a spinal disorder commonly reported as a clinical syndrome in domestic dogs, although is rarely recognized in felines (De Risio et al 2000). Compressive lesions at the cauda equina (i.e. sacral caudal and L7 spinal nerve and nerve roots) (De Risio et al 2000) combined with other abnormalities (e.g. trauma, vascular causes, infectious and inflammatory diseases, and neoplasia), lead to degenerative changes including soft tissue hypertrophy of supporting ligamentous structures such as the ligamentum flavum (Sharp and Wheeler 2005). The DLSS or lumbosacral syndrome may cause signs in the pelvic limbs, bladder, anal sphincter, and tail innervations. These can range from flaccid weakness to paralysis of pelvic limbs, including reluctance to movement, pelvic limb gait abnormalities, uni or bilateral lameness, paraesthesia or dysesthesia, tail paresis or paralysis, and urinary or fecal incontinence (De Risio et al 2000). However, the most ...

All of the named peripheral nerves can be identified by the end of the eighth week. As viscera and muscle masses shift in their position, their nerves accommodate the shifts by increasing in length. The heart and diaphragm receive most of their innervation when they are in the cervical region. Since their nerves (superior, middle and inferior cervical cardiac nerves of the heart and phrenic nerve of the diaphragm) follow them as they migrate caudally, they begin in the neck and descend through the root of the neck and thorax. Likewise, the larynx receives its motor innervation from the vagus when the aortic arches are farther cranially. When the arches migrate caudally with the heart, the recurrent laryngeal nerve follows causing it to recur in its course to the larynx. In the adult it passes around the aortic arch and ligamentum arteriosum on the left, which were derived from the fourth and sixth arches, respectively. Since on the right side the distal part of the sixth arch disappears, the ...
