Results:. The skeleton of a 57 year old male presents anatomical variations of lumbar vertebrae. He has six, in contrast to normal five lumbar vertebrae whereas the other levels are normally, 7 cervical, 12 thoracic, 1 sacral and 1 coccygeal vertebrae.. The first lumbar vertebra is obviously differently from others in that its transverse processes are short and articulated with the malformed ribs. The pair of this malformed ribs is the 13th, an extra pair additional to the normal 12 pairs. The right one is 4 centimeters long while the left is 3.5 centimeters. Additional malformed of pair of ribs in this case made 3 pairs of floating ribs. Anatomy of the second to fifth lumbar vertebrae are similar to the typical lumbar vertebrae.. The sixth lumbar vertebra situated below the fifth and articulated to the first sacral vertebra. Although in general the body of the sixth lumbar vertebra configuration is similar to the other lumbar vertebrae but its spinous process projected posterior, is short with ...

The achievement of a given change score on a valid outcome instrument is commonly used to indicate whether a clinically relevant change has occurred after spine surgery. However, the achievement of such a change score can be dependent on baseline values and does not necessarily indicate whether the patient is satisfied with the current state. The achievement of an absolute score equivalent to a patient acceptable symptom state (PASS) may be a more stringent measure to indicate treatment success.This study aimed to estimate the score on the Oswestry Disability Index (ODI, version 2.1a; 0-100) corresponding to a PASS in patients who had undergone surgery for degenerative disorders of the lumbar spine.This is a cross-sectional study of diagnostic accuracy using follow-up data from an international spine surgery registry.The sample includes 1,288 patients with degenerative lumbar spine disorders who had undergone elective spine surgery, registered in the EUROSPINE Spine Tango Spine Surgery Registry.The main

Study Design. Particles of a proprietary polyolefin rubber compound used in a lumbar disc prosthesis were generated in vitro and tested for biocompatibility in two animal models. |br|Objective. To characterize any tissue response to polyolefin rubber particles. Summary of Background Data. Intervertebral disc prostheses are emerging as alternatives to fusion techniques for the treatment of symptomatic disc degeneration. The biocompatibility of all novel components used in the construction of these devices must be verified before they can be considered for general use. Methods. Laboratory-generated polyolefin rubber particles were either injected into dorsal subcutaneous air pouches of 30 rats or placed directly onto the lumbosacral dura and nerve roots of 9 sheep. Histologic sections of tissues from, and remote from, the site of implantation were examined for evidence of inflammation and wound-healing responses. Results. Polyolefin rubber particle debris induced a tissue response that was consistent with

Due to new information about the pathophysiology and biomechanics of degenerative lumbar spine disease, the surgical treatment of this disease has undergone a significant increase over the past forty years.. Novel diagnostic approaches and the development of new materials provided the impetus to produce new types of instrumentation, and these instruments have led to the modernization of interbody fusion including PLIF, TLIF and ALIF methods. These interventions are currently performed in either an open mini-invasive or endoscopic manner. The open interventions are indicated in cases where the spinal canal stenosis is caused by severe degenerative lesions affecting the motion of intervertebral discs, joints, ligaments, or vertebral arch. Despite the development of other surgical techniques (e.g., functional disc substitutes, dynamic stabilization), the posterior interbody fusion represents a powerful approach in the surgical treatment of degenerative stenosis of the spinal canal.. The PLIF method ...

Context: Intraoperative blood loss during open lumbar spine surgery is associated with adverse events and is a contributor to higher medical costs. Intraoperative hypothermia has been shown to increase blood loss and postoperative allogeneic blood transfusion rates in other realms of orthopedic surgery, but it has not been studied extensively in patients undergoing spine surgery. Objective: To determine whether a clinically relevant association exists between intraoperative core body temperature and blood loss or transfusion rates in adult patients undergoing open lumbar spine surgery. Methods: In this retrospective medical record review, the surgical records of 174 adult patients who underwent open, nonmicroscopically assisted lumbar spine surgery performed by a single surgeon at a single institution were evaluated. Maximum, minimum, and average temperature, hypothermic temperature, and temperature range parameters were compared with intraoperative, total, and net blood loss and blood ...

There are five lumbar vertebrae. These vertebrae are the largest of the true or mobile vertebrae. They are distinguishable by their large size and lack of transverse foramina and costal facets. They form a strong column of support at the base of the vertebral column. The articular processes of the lumbar vertebrae are robust having their facets oriented in the sagittal plane to provide for flexion and extension movements of this region of the vertebral column. They have thick pedicles arising from the cranial aspect of the vertebral body. The laminae are thick and short. They project caudally to unite as thick, quadrilateral spinous processes. The vertebral bodies have a large elliptical shape when viewed from above ...

A stabilization system for a human spine is provided. The stabilization system may include one or more dynamic interbody devices and/or one or more dynamic posterior stabilization systems. The dynamic interbody devices may provide for coupled axial rotation and lateral bending of vertebrae adjacent to the dynamic interbody devices. The dynamic posterior stabilization systems may provide resistance to movement that mimics the resistance provided by a normal functional spinal unit.

The spinous process is thick, broad, and somewhat quadrilateral; it projects backward and ends in a rough, uneven border, thickest below where it is occasionally notched.[1]. The superior and inferior articular processes are well-defined, projecting respectively upward and downward from the junctions of pedicles and laminae. The facets on the superior processes are concave, and look backward and medialward; those on the inferior are convex, and are directed forward and lateralward. The former are wider apart than the latter since in the articulated column, the inferior articular processes are embraced by the superior processes of the subjacent vertebra.[1]. The transverse processes are long and slender. They are horizontal in the upper three lumbar vertebrae and incline a little upward in the lower two. In the upper three vertebrae they arise from the junctions of the pedicles and laminae, but in the lower two they are set farther forward and spring from the pedicles and posterior parts of the ...

Disc Height and Sagittal Alignment in Operated and Non-Operated Levels in the Lumbar Spine at Long-Term Follow-Up: A Case-Control Study

No leak was seen on repeat angiography. BP was stabilized and patient improved hemodynamically after the procedure and within 3 hours after first episode of hypotension. 3 units whole blood, 4 units of packed cells and 4 units of fresh frozen plasmas were administered during this period of 3 hours. Patient was kept in intensive care unit for 2 days and then was shifted to room. Patient was discharged on 8th post-operative day. On 6th month follow up, patient was symptom free, without any vascular of neurological complications.. Discussion. Improvements in surgical techniques and instrumentation have allowed for enhanced and better outcomes in lumbar spine surgery. Though very routine and usually safe, lumbar disc surgery can have array of complications. For post-operative infections, rates in the literature vary widely (0.3% to 9%) depending on preoperative diagnosis, the type of procedure and patient population [12-15]. The infections can have problematic sequelae including failure of fixation, ...

s are very strong, directed backward from the upper part of the vertebral body; consequently, the inferior vertebral notches are of considerable depth. The pedicles change in morphology from the upper lumbar to the lower lumbar. They increase in sagittal width from 9 mm to up to 18 mm at L5. They increase in angulation in the axial plane from 10 degrees to 20 degrees by L5. The pedicle is sometimes used as a portal of entrance into the vertebral body for fixation with pedicle screws or for placement of bone cement ...

Hello Cristy,. Before you start training the client, find out for sure which lumbar vertebrae have been fused. In your post you put L3-L6. FYI, there are only 5 lumbar vertebrae.. After you find out, I believe it is important for you to understand the function of the entire vertebral column, but more so the limitations your client will have as a consequence of spinal fusion. Too, dont forget the muscles that originate and attach on the lumbar spine. You will have to take this into consideration when designing the program for your client.. I hope this gives you a bit of direction.. Best!. ...

Since the enunciation by Johannsen in 1903 of the pure line doctrine inbred strains have been used for various experimental purposes in the belief that they offer the highest attainable level of uniformity. This view is now known to be of limited validity. One reason is that pure lines are not always as genetically pure as a simple Mendelian calculus would predict. Another is that for many characters inbred organisms are peculiarly sensitive during their development to environmental causes of variation (see the references cited by Grüneberg (1954), McLaren & Michie (1954a), and Biggers & Claringbold (1954); to these should be added Hagedoorn (1939), Mather (1946), Lerner (1954), and Kushner & Kameneva (1954))..

Yeah. Traditional hyperextensions arent the way to go. You should not be moving a loaded lumbar spine. You need to train to stabilize it. This means isometric exercises that train the muscles around your lumbar spine to resist movement and thus to protect the spine. So exercises like planks, Pallof presses are good. Glute bridges require you to hold your lower back in position, so they would be OK if you are careful that the movement comes from your hips, not from your lumbar spine. You can do a modified hyperextension that really only goes from slightly flexed to neutral, not into extension. You can do that off the end of a bench, or at many commercial gyms that have a hyperextension bench. You can train your hips and thoracic spine for mobility, but your lumbar spine for stability. Twisting at the lumbar level should be avoided. No situps or traditional crunches. Look up something called McGill curlups, or McGill crunches ...

Study design: A retrospective chart review study combined with data from the Oswestry Disability survey (ODI), and SF-36 Quality of life questionnaires. Objectives: This study is intended to identify and quantify Posterior lumbar interbody fusion (PUF) surgery successes and compare this information to data on Anterior lumbar interbody fusion (ALIF) surgery. Quality of life, patient satisfaction, fusion stability, continued nerve decompression and need for more surgery are parameters investigated. We use surveys combined with chart review of PLIF patients and compare data with that of previous ALIF research. Background: Lumbar interbody fusion is generally an elective surgical procedure performed to relieve low back pain from segmental instability and/or nerve root compression in the lumbar spine. Indications for this surgery range from intractable back pain and radicular pain occurring over time to sudden nerve compression. Progressive weakness is an urgent indication for surgery.

Clinical diagnoses on 1st operation were degenerative spondylolisthesis of four cases, chronic degenerative disc disease with spinal stenosis of six cases, and recurred herniated lumbar disc disease of one case. We treated eight cases by posterior lumbar interbody fusion, one case by 360degrees fusion, and two cases by pedicle screw fixation only. Disc degeneration on adjacent segment to spinal fusion existed already in nine among 11 patients before spinal fusion. Types of adjacent segment degeneration after spinal fusion were disc degeneration of two cases, lumbar instability of three cases, lumbar stenosis of four cases, and lumbar instability and stenosis of two cases. Most patients complained of low back pain due to disc degeneration and instability, and some patients complained of leg and buttock pain due to stenosis. Time interval from 1st operation to reoperation was 20 months through 99 months, mean time interval was 57 months ...

Lumbar interbody fusion has become a widely accepted treatment for painful conditions of the lumbar spine from degenerative disc disease, instability, and stenosis.1 Axial back pain and radicular symptomatology can be dramatically improved from interbody fusion. When outcomes are evaluated, higher fusion rates and improved pain reduction can be anticipated than from posterolateral fusion alone.2 The benefits of interbody fusion indirectly decompressing the neural elements have been known since the 1990s. Morphometric assessment of neural canal and neural foraminal dimension after anterior lumbar interbody fusion supports the concept of indirect decompression.3 Interbody fusion does pose a risk for complications. In an attempt to lessen the risk of severe complications that may occur with anterior or posterior approaches to the spine and to offer less invasive surgical alternatives, lateral lumbar interbody fusion has become popularized. Although this technique recommends electromyography (EMG) ...

Anterior lumbar interbody fusion (ALIF) is a spine surgery that involves approaching the spine from the front (anterior) of the body to remove all or part of a herniated disc from in between two adjacent vertebrae (interbody) in the lower back (lumbar spine), then fusing, or joining together, the vertebrae on either side of the remaining disc space using bone graft or bone graft substitute.. The graft material acts as a binding medium and also helps maintain normal disc height - as the body heals, the vertebral bone and bone graft eventually grow together and stabilize the spine. Instrumentation, such as rods, screws, plates, cages, hooks and wire also may be used to create an internal cast to support the vertebral structure during the healing process.. Depending on your condition and your surgeons training, experience and preferred methodology, an ALIF may be done alone or in conjunction with another spinal fusion approach. Please discuss your fusion approach options thoroughly with your ...

During the period 1989-1999, a number of patients underwent an ALIF-procedure. Anterior Lumbar Interbody Fusion procedure (ALIF) is a type of lumbar spinal fusion. The approach of the lumbar region is by incision of the abdominal wall. The intervertebral disc is removed and replaced by a bone graft. These patients form the population of this study. The goal of this study is to evaluate their current medical condition and to determine the clinical outcome.. The clinical result will be stipulated by means of standardized questionnaires (VAS-score, Oswestry low Back Pain Questionnaire and SF-36) ...

Object. The authors conducted a retrospective study to provide an independent evaluation of posterior lumbar interbody fusion (PLIF) in which impacted carbon cages were used. Interbody cages have been developed to replace tricortical interbody grafts in anterior and PLIF procedures. Superior fusion rates and clinical outcomes have been claimed by the developers.. Methods. In a retrospective study, the authors evaluated 71 consecutive patients in whom surgery was performed between 1995 and 1997. The median follow-up period was 28 months. Clinical outcome was assessed using the Prolo scale. Fusion results were interpreted by an independent radiologist.. The fusion rate was 90%. Overall, 67% of the patients were satisfied with their outcome and would undergo the same operation again. Based on the results of the Prolo scale, however, in only 39% of the patients were excellent or good results achieved. Forty-six percent of the work-eligible patients resumed their working activity. Clinical outcome ...

Care guide for Minimally Invasive Anterior Lumbar Interbody Fusion (Discharge Care). Includes: possible causes, signs and symptoms, standard treatment options and means of care and support.

AP lumbar interbody fusion surgery is associated with a more than two times higher complication rate, significantly increased blood loss, and longer operative and hospitalization times than both percutaneous and open TLIF for lumbar disc degeneration and instability.

Oblique lateral lumbar interbody fusion (OLLIF) is a minimally invasive keyhole procedure used to achieve lumbar vertebrae spine fusion. Unlike other spinal fusion procedures, OLLIF is performed as an outpatient surgery for many people. Here are the many benefits of the oblique lateral lumbar interbody fusion procedure.. No. 1: It is a Non-Traditional Approach. The OLLIF procedure is performed via a small 1 ½ centimeter incision on the patients side. Because the lateral approach involves a small incision, there is less scarring and pain. In addition, the surgeon does not have to move healthy bone structures, nerve bundles, or major muscle groups.. No. 2: Access Granted. The OLLIF is a simple, effective approach to spinal fusion. A small probe is used to dilate the muscles and nerves so the surgeon can access and removed the disease or damaged disc and bone components.. No. 3: Implant Material and Bone Graft Provides Stability. With the oblique lateral lumbar fusion procedure, a biocompatible ...

ANOVA was performed to prove the null hypothesis defined as no change in the ODI, VAS LBP, and VAS LP when measured before, 1 month, 6 months, and 12 months after MIS-TLIF, respectively. The results showed a significant time effect for ODI with a Wilks lambda=0.5, F(3, 27), p,0.001, η2=0.95). In addition, VAS LBP (Wilks lambda=0.381, F(3, 27), p,0.001, η2=0.619) and VAS LP (Wilks lambda=0.012, F(3, 27), p,0.001, η2=0.988) showed a similar significance. Follow-up comparisons revealed that each pairwise difference was significant in all three measurements (p,0.01). Significant improvement was observed in the respective ODI, VAS LBP, and VAS LP scores over time, suggesting that MIS-TLIF improved the participants functional outcome. All patients attained radiological fusion at 12 months with 18 (60%) meeting the Rays criteria of bony healing at 6-month follow-up (Table 2 ...

Objective: Posterior lumbar interbody fusion (PLIF) surgery is a commonly used procedure for degenerative lumbar instability. Locally harvested bone is usually inserted into intervertebral cages to increase fusion rate. The fusion rate of intervertebral cages without bone application remains unknown. The aim was to retrospectively analyze fusion rates of intervertebral polyetheretherketone and titan cages implanted without autologous bone grafting in posterior lumbar interbody fusion surgery using 3D computer tomography scanning.. Method: Forty patients between the age of 43 and 83 years with mono- or bisegmental degenerative instability were included. Polyetheretherketone cages were used in 28 segments in 25 patients (PEEK group) and titanium cages were used in 19 segments in 15 patients (titanium group) undergoing PLIF surgery with pedicle screws. All patients were treated for degenerative lumbar instability assessed by MRI, CT and/or dynamic lumbar x-ray. Primary outcome parameter was ...

Surgical Procedures of Lumbar Spine Fusion on orangecountysurgeons.org During lumbar spine fusion, two or more vertebrae located in the spines lumbar region are linked together. To perform the procedure, damaged discs are removed first. Then the empty space is filled with pieces of bone, sometimes taken from the patients pelvic bone.

One advantage of an endoscopic approach to treating lumbar spinal stenosis is preservation of spine stability and the adjacent anatomy, and there is a decrease in adjacent segment disc degeneration. The purpose of this study was to discuss the clinical efficacy of percutaneous transforaminal endoscopic decompression for the treatment of lumbar spinal stenosis (LSS). This is a retrospective study. From September 2012 to June 2017, 45 patients who were diagnosed with LSS underwent the treatment of percutaneous transforaminal endoscopic decompression (PTED) and were followed up at 1 week, 3 months and 1 year postoperatively. Low back pain and leg pain were measured by Visual Analogue Scale scoring methods (VAS-back and VAS-leg), while functional outcomes were assessed by using the Oswestry Disability Index (ODI). All patients had one-level lumbar spinal stenosis. The most common type of stenosis was lateral recess stenosis (n = 22; 48.9%), followed by central stenosis (n = 13; 28.9%) and foraminal stenosis

A lumbar laminectomy is a surgical procedure that is also known as an open decompression. The procedure is designed to relieve the pressure that is on the spinal nerve or spinal cord by opening or widening the spinal canal. During the procedure, the lamina which is a small section of the bone on the spine is removed so that there is more room for the nerves. An open decompression, or lumbar laminectomy is typically suggested by a physician for those patients who suffer from back pain caused by neural impingement. The surgical procedure relieves the pressure by enlarging the spinal canal. Continue reading What is Lumbar Laminectomy? →. ...

Spine fusion surgery joins two or more small spine bones (vertebrae) together. It is used to treat a variety of conditions, such as degenerative disc disease, spinal stenosis, and scoliosis.. The goal of spine fusion surgery is to lessen pain at the vertebrae that are being joined by stopping that joint from moving.. There is considerable debate about the effectiveness of spine fusion surgery for degenerative disc disease. As many as 1 in 3 patients who undergo spine fusion do not report improvements in pain or functional status. Additionally, there are currently no evidence-based selection criteria to help surgeons determine which patients will respond to spine fusion surgery and which will not benefit.. CERTAIN is interested in better understanding which patients are more likely to benefit from spinal fusion surgery for degenerative disc disease. The Spine Fusion study will partner with spine surgery clinics to invite patients to participate in research activities designed to identify the ...

Evaluation of a novel tool for bone graft delivery in minimally invasive transforaminal lumbar interbody fusion Jeffrey B Kleiner, Hannah M Kleiner, E John Grimberg Jr, Stefanie J Throlson The Spine Center of Innovation, The Medical Center of Aurora, Aurora, CO, USA Study design: Disk material removed (DMR) during L4-5 and L5-S1 transforaminal lumbar interbody fusion (T-LIF) surgery was compared to the corresponding bone graft (BG) volumes inserted at the time of fusion. A novel BG delivery tool (BGDT) was used to apply the BG. In order to establish the percentage of DMR during T-LIF, it was compared to DMR during anterior diskectomy (AD). This study was performed prospectively. Summary of background data: Minimal information is available as to the volume of DMR during a T-LIF procedure, and the relationship between DMR and BG delivered is unknown. BG insertion has been empiric and technically challenging. Since the volume of BG applied to the prepared disk space likely impacts the probability of

TY - JOUR. T1 - Estimating lumbar bone mineral density from routine radiographs of the lumbar spine. AU - Michel, B. A.. AU - Bjorkengren, A. G.. AU - Lambert, E.. AU - Lane, Nancy E. AU - Fries, J. F.. AU - Bloch, D. A.. PY - 1993/3. Y1 - 1993/3. N2 - To evaluate the information content of lateral lumbar films with respect to bone mineral content, we compared reading criteria with values obtained by quantitative computed tomography (CT) of L1 at baseline and after 5 years. The highest correlations with mineral content were found for the criteria overall assessment of the vertebra, vertebral body density versus soft tissue, and amount of trabeculations. These three reading criteria yielded higher correlations with CT scores in subjects with lower body mass index. Changes in mineral content over the 5-year period could not be read adequately, the average difference representing only a loss of about 10% in the study subjects. We conclude that a rough estimate of bone density can be obtained ...

The lumbar vertebrae are stacked to form a continuous column in order from superior (L1 or first lumbar vertebra) to inferior (L5 or fifth lumbar vertebra). Together they create the concave lumbar curvature in the lower back. Connecting each vertebra to its neighbouring vertebra is an intervertebral disc made of tough fibrocartilage with a jelly-like centre. The outer layer of the intervertebral disc, the annulus fibrosus, holds the vertebrae together and provides strength and flexibility to the back during movement. The jelly-like nucleus pulposus acts as a shock absorber to resist the strain and pressure exerted on the lower back.. The lumbar vertebrae are some of the largest and heaviest vertebrae in the spine, second in size only to the sacrum. A cylinder of bone known as the vertebral body makes up the majority of the lumbar vertebraes mass and bears most of the bodys weight. The vertebral foramen is a large, triangular opening in the center of the vertebra that provides space for the ...

Lumbar interbody fusion: techniques, indications and comparison of interbody fusion options including PLIF, TLIF, MI-TLIF, OLIF/ATP, LLIF and ALIF

In addition to the traditional one-level fusion or decompression surgery that is done for lumbar degenerative disc disease or spinal stenosis, respectively, there are a number of surgical alternatives available. Several of the most common ones include:. Artificial Disc Replacement. Artificial disc technology can be used in specific cases of lumbar degenerative disc disease.. Motion Preservation Technologies. It should be known that while spinal fusion has been a classical treatment for ongoing pain and disability from the lumbar spine, alternatives to fusion do exist for posterior conditions (problems in the back of the lumbar spine) such as spinal stenosis. Inserting an interspinous process spacer, such as the X-STOP device, can actually preserve motion as opposed to stopping it via fusion.. Vertebral Augmentation. A surgery called vertebral augmentation may be done to treat pathological fractures from tumors or osteoporosis.. Multilevel Lumbar Fusion. Lumbar spine fusion surgery for ...

An intervertebral implant for fusing vertebrae is disclosed. The implant has a body with curved, substantially parallel posterior and anterior faces separated by two narrow implant ends, superior and inferior faces having a plurality of undulating surfaces for contacting upper and lower vertebral endplates, and at least one depression in the anterior or posterior face for engagement by an insertion tool, at least two vertical through-channels extending through the implant from the superior face to the inferior face, a chamfer on the superior and inferior surfaces at one of the narrow implant ends, and a beveled edge along a perimeter of the superior and inferior faces. The arcuate implant configuration and the chamfers on the superior and inferior faces at the narrow end facilitate insertion of the implant from a transforaminal approach into a symmetric position about the midline of the spine so that a single implant provides balanced support to the spinal column. The implant may include radiopaque

ALIF is generally used to treat back or leg pain caused by degenerative disc disease. The surgeon will stabilize the spine by fusing vertebrae together with bone graft material.

Our minimally invasive lateral lumbar interbody fusion procedure helps patients alleviate the pain associated with a compressed nerve in the lower ...

Lumbar spinal stenosis with neurogenic claudication is a condition in which the area where the spinal nerves traverse in the lumbar spine becomes narrowed, causing compression of the nerves. When the nerves in the lumbar region become compressed, this may cause any combination of pain, weakness, numbness, and/or tingling in the low back and legs. These symptoms are typically more prominent with standing and walking, and decrease when sitting down or leaning forward. For example, patients with lumbar spinal stenosis with neurogenic claudication typically report the following scenario: low back and/or leg pain with weakness, heaviness, numbness, tingling, pins and needles, etc. This constellation of symptoms worsens after walking a few blocks and resolves with sitting or if theyre able to lean forward while using a walker or a shopping cart. ...

An interbody fusion is a method of fusing the lumbar spine that involves removing the damaged intervertebral disk. In a lateral lumbar interbody fusion, the surgeon accesses the spine through incisions in the side, rather than the front or back.
