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

An artificial functional spinal unit is provided comprising, generally, an expandable artificial intervertebral implant that can be placed via a posterior surgical approach and used in conjunction with one or more artificial facet joints to provide an anatomically correct range of motion. Expandable artificial intervertebral implants in both lordotic and non-lordotic designs are disclosed, as well as lordotic and non-lordotic expandable cages for both PLIF (posterior lumber interbody fusion) and TLIF (transforaminal lumbar interbody fusion) procedures. The expandable implants may have various shapes, such as round, square, rectangular, banana-shaped, kidney-shaped, or other similar shapes. By virtue of their posteriorly implanted approach, the disclosed artificial FSUs allow for posterior decompression of the neural elements, reconstruction of all or part of the natural functional spinal unit, restoration and maintenance of lordosis, maintenance of motion, and restoration and maintenance of disc space

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 ...
This is Dr. David. it sounds like you had a lumbar spine MRI scan.. Spondylolisthesis is the forward displacement of a vertebra, especially the fourth and fifth lumbar vertebra, grade 1 is the mildest. retrolisthesis is a posterior displacement of one vertebral body with respect to the adjacent vertebrae to a degree less than a luxation (dislocation). degenerative changes is arthritis type of inflammatory changes.. osteophytes are extra bone spur growths. facet joints are one of the joints of the spine which connect the upper and lower vertebral bones and are close to nerves which exit the spinal cord.. being overweight can cause disk space narrowing between the bones of the spine.. no bone fractures are seen. no bone lesions.. you have some plaques in the blood vessels which comes with age in your aorta which is close to your spine.. how old are you?. are you having back pain?. are you overweight? ...

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, ...

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)).. In this paper we consider the degree to which these two qualifications are exemplified by the variation of the number of lumbar vertebrae in mice.. As in the previous paper vertebral types will be denoted by the following symbols: 6/6 = six lumbar vertebrae on each side.. ...

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 ...

Miriam was originally scheduled for her regular six-month expansion today (Monday, Dec. 11). We went in for her pre-op visit last week expecting just to update health history and confirm a simple expansion of both rods.. Youd think we would know by now that its never simple.. This time, Miriams x-rays revealed that the lower anchor of her rib-to-spine rod (which is supposed to hook over one of her lumbar vertebrae) has become detached. And by detached, I mean that the tension in the rod has very slowly pulled the anchor through the bone until it has come free (in her doctors terms, it has "migrated" through the bone). Its a surprise, but not a shock for a couple of reasons. First of all, it has happened before. The rod was originally hooked to the vertebra below this one, and after 18 months (Nov. 2014) it migrated through that attachment point. Second, the attachment point on her back has become really pronounced under the skin. It has always been noticeable, but it is really obvious ...

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. Orthopedic surgeons
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 ...
