Spondylolytic fractures. (1/88)
A method is described whereby fractures of the neural arch similar to those in spondylolysis are produced experimentally. The forces, bending moments and displacements required to initiate the fractures are given; The mechanical aspects in the aetiology of spondylolysis are explained by a simplified two-dimensional force analysis. (+info)Delayed vertebral slip and adjacent disc degeneration with an isthmic defect of the fifth lumbar vertebra. (2/88)
We reviewed the radiographs of 325 unselected patients with defects in the pars interarticularis of L5 to study whether the incidence of vertebral slip in spondylolysis of L5 remained unchanged after the age of 20 years. MRI was also carried out on 111 of the patients to investigate the relationship between the shape of the transverse process of L5 and the degeneration of the discs adjacent to this level. The incidence of spondylolisthesis increased with age from 17% in the second decade to 51% in the sixth. The transverse process was significantly more slender in patients with less degeneration at L4/5 and advanced degeneration at L5/S1 than in patients with advanced degeneration at L4/5 and less degeneration at L5/S1. Vertebral slip secondary to an isthmic defect of L5 after the age of 20 years was confirmed and the adjacent disc degeneration was significantly related to the vertical thickness of the transverse process of L5. (+info)Does the iliolumbar ligament prevent anterior displacement of the fifth lumbar vertebra with defects of the pars? (3/88)
We studied 23 patients with spondylolysis of the fifth lumbar vertebra (L5) and 20 with spondylolytic spondylolisthesis at this level. All were more than 40 years of age. The transverse processes at L5 were significantly wider in the former group than in the latter. We also dissected 56 cadavers to study the morphological relationship between the transverse process of L5 and the iliolumbar ligament, and found that the wider transverse process is associated with increased width of the posterior band of the iliolumbar ligament. If a patient with pars defects has wide transverse processes at L5, the lumbosacral junction may be stabilised by wide posterior bands of the iliolumbar ligament and the fifth lumbar vertebra by the ligament, preventing anterior displacement. (+info)Spondylolysis: a critical review. (4/88)
AIM: To provide an understanding of the current concepts in the natural history, pathophysiology, diagnosis, and treatment of spondylolysis based on the available medical literature. METHODS: Articles were selected for review by the following methods: (a) MEDLINE searches with review of abstracts to select relevant articles; (b) review of multiple textbooks considered likely to contain information on spondylolysis; (c) review of references in articles identified by (a) and (b). Over 125 articles were ultimately reviewed fully. Publications were selected for inclusion in this article on the basis of perceived scientific and historical merit, particularly as thought to be relevant to achieving the stated purpose of this review. As no controlled clinical trials were identified, this could not be used as an inclusion criterion. CONCLUSIONS: Isthmic spondylolysis is considered to represent a fatigue fracture of the pars interarticularis of the neural arch. There is a relatively high incidence of radiographically identified spondylolysis in the general population, but the vast majority of these lesions probably occur without associated symptoms. Symptomatic pars lesions appear to be particularly a clinical problem in adolescents, especially adolescent athletes. The optimal diagnostic and treatment algorithms are not well identified in the current literature. Multiple imaging studies may have a role in the diagnosis of a pars lesion, and treatment seems likely to require at least relative rest and physical rehabilitation with consideration of bracing or, rarely, surgical intervention depending on the clinical context. (+info)Direct repair of defect in lumbar spondylolysis and mild isthmic spondylolisthesis by bone grafting, with or without facet joint fusion. (5/88)
Forty-six patients with lumbar spondylolysis and mild isthmic spondylolisthesis were managed with direct repair of the defect with or without facet joint fusion in the affected segment. There were 24 males and 22 females, ranging in age from 15 to 56 years (average, 38.2 years). These patients had experienced clinical symptoms due to spondylolysis for between 4 months and 20 years (average, 5.3 years). Of 46 patients, 28 had no spondylolisthesis, 11 had Meyerding grade I vertebral slippage and 7 had grade II. Direct repair of 98 defects was performed on these patients. Twenty-six patients, in whom the disc adjacent to the defect was determined as degenerative by magnetic resonance imaging (MRI), simultaneously underwent facet joint fusion; 17 in one segment and 9 in two segments. The average period of follow-up was 50 months (24-92 months). Ninety-four defects achieved bony healing. As a result, 28 patients were graded as having an excellent outcome, 15 good, and 3 fair. Bone grafting in the defects achieves union between the loose lamina and the anterior element of lumbar vertebrae, and reconstructs the anatomic structure and physiologic functions of the lumbar vertebrae. There was no significant difference in outcome between the spondylolytic/spondylolisthetic patients with non-degenerative disc, who were treated with direct repair of defect only, and those with degenerative disc, who additionally underwent a fusion procedure (P > 0.05). The present series demonstrates a satisfactory result and a high rate of bony healing of the pars defect by this operative procedure in patients with lumbar spondylolysis and mild isthmic spondylolisthesis. Preoperative assessment of the disc degeneration with MRI is of great assistance in making the protocol choice of whether to opt for fusion. (+info)Lumbosacral transitional vertebrae and nerve-root symptoms. (6/88)
Transitional vertebrae (TV) may be one of the risk factors for lumbar disc herniation. It is not clear, however, whether the presence of TV can affect the development of nerve-root symptoms. Our aim was to clarify this relationship. A total of 501 patients with lumbar degenerative disease and nerve-root symptoms was studied in respect of their level and the presence of TV. As a control group, 508 patients without low back pain or nerve-root symptoms were studied to establish the incidence of TV. In patients with disc herniation, the incidence was statistically higher and the mean age lower in patients with TV than in those without. In most patients, the symptomatic disc level was just above the TV. Similarly, in those with stenosis of the spinal canal without spondylolisthesis, the symptomatic disc level was most commonly just above the TV.

The purpose of this study was to evaluate the healing capacity of fatigue fractures of the pars interarticularis in young elite athletes. Between 1991 and 2000, a fatigue fracture of the pars interarticularis was diagnosed in 34 highly competitive athletes. The study group included 28 athletes with a mean age of 17.2 years at diagnosis (range 12-27 years). The average time per week dedicated to sports was 10.9 h. Diagnosis was made with both planar and single-photon-emission computed tomographic (SPECT) bone scintigraphy and computed tomographic (CT) scan. Lesions were classified into three groups according to their distribution on the scintigram: unilateral, bilateral, or "pseudo-bilateral" (asymmetrical tracer uptake). The study was limited to athletes with subtle fractures, which means that they had normal radiographs and positive bone scans. All subjects were braced for a mean time of 15.9 weeks (range 12-32 weeks). We looked at healing of the fracture, subjective outcome, and sports resumption in the three groups. The athletes were reviewed after an average of 13.2 months (range 3-51 months), and a second CT scan was performed to evaluate osseous healing. Healing of the fracture was noted in all 11 athletes with a unilateral lesion, in five out of nine athletes with a bilateral lesion and in none of the eight athletes with a pseudo-bilateral lesion. Twenty-three athletes (82.2%) rated the outcome as excellent, three athletes (10.7%) as good, and two (7.1%) as fair. Twenty-five athletes (89.3%) managed to return to their same level of competitive activity within an average of 5.5 months after the onset of treatment. There was no difference in outcome or in sports resumption between the three groups. Our data suggest that osseous healing is most likely to occur in unilateral active spondylolysis. Chances of bony healing diminish when the fracture is bilateral, and diminish even further when it is pseudo-bilateral. Non-union does not seem to compromise the overall outcome or sports resumption in the short term.

We studied prospectively 22 young athletes who had undergone surgical treatment for lumbar spondylolysis. There were 15 men and seven women with a mean age of 20.2 years (15 to 34). Of these, 13 were professional footballers, four professional cricketers, three hockey players, one a tennis player and one a golfer. Preoperative assessment included plain radiography, single positron-emission CT, planar bone scanning and reverse-gantry CT. In all patients the Oswestry disability index (ODI) and in 19 the Short-Form 36 (SF-36) scores were determined preoperatively, and both were measured again after two years in all patients. Three patients had a Scott's fusion and 19 a Buck's fusion. The mean duration of back pain before surgery was 9.4 months (6 to 36). The mean size of the defect as determined by CT was 3.5 mm (1 to 8) and the mean preoperative and postoperative ODIs were 39.5 (SD 8.7) and 10.7 (SD 12.9), respectively. The mean scores for the physical component of the SF-36 improved from 27.1 (SD 5.1) to 47.8 (SD 7.7). The mean scores for the mental health component of the SF-36 improved from 39.0 (SD 3.9) to 55.4 (SD 6.3) with p < 0.001. After rehabilitation for a mean of seven months (4 to 10) 18 patients (82%) returned to their previous sporting activity. (+info)Spondylolysis is a defect or stress fracture in the pars interarticularis, which is a part of the vertebra in the lower back (lumbar spine). This condition most commonly affects young athletes who participate in sports that involve repetitive hyperextension of the lower back, such as gymnastics, football, and dance. Spondylolysis can cause lower back pain and stiffness, and if left untreated, it may lead to spondylolisthesis, a condition where one vertebra slips forward over the one below it. In some cases, spondylolysis may not cause any symptoms and may be discovered during an imaging test performed for another reason.
Spondylolisthesis is a medical condition that affects the spine, specifically the vertebrae in the lower back (lumbar region). It occurs when one vertebra slips forward and onto the vertebra below it. This slippage can lead to narrowing of the spinal canal and compression of the nerves exiting the spine, causing pain and discomfort. The condition can be congenital, degenerative, or result from trauma or injury. Symptoms may include lower back pain, stiffness, and radiating pain down the legs. Treatment options range from physical therapy and pain management to surgical intervention in severe cases.
The lumbar vertebrae are the five largest and strongest vertebrae in the human spine, located in the lower back region. They are responsible for bearing most of the body's weight and providing stability during movement. The lumbar vertebrae have a characteristic shape, with a large body in the front, which serves as the main weight-bearing structure, and a bony ring in the back, formed by the pedicles, laminae, and processes. This ring encloses and protects the spinal cord and nerves. The lumbar vertebrae are numbered L1 to L5, starting from the uppermost one. They allow for flexion, extension, lateral bending, and rotation movements of the trunk.
Stress fractures are defined as small cracks or severe bruising in bones that occur from repetitive stress or overuse. They most commonly occur in weight-bearing bones, such as the legs and feet, but can also occur in the arms, hips, and back. Stress fractures differ from regular fractures because they typically do not result from a single, traumatic event. Instead, they are caused by repeated stress on the bone that results in microscopic damage over time. Athletes, military personnel, and individuals who engage in high-impact activities or have weak bones (osteoporosis) are at increased risk of developing stress fractures. Symptoms may include pain, swelling, tenderness, and difficulty walking or bearing weight on the affected bone.
A zygapophyseal joint, also known as a facet joint, is a type of synovial joint that connects the articulating processes of adjacent vertebrae in the spine. These joints are formed by the superior and inferior articular processes of the vertebral bodies and are covered with hyaline cartilage. They allow for smooth movement between the vertebrae, providing stability and limiting excessive motion while allowing flexibility in the spine. The zygapophyseal joints are supported by a capsule and ligaments that help to maintain their alignment and restrict abnormal movements. These joints can become sources of pain and discomfort when they become inflamed or damaged due to conditions such as arthritis, degenerative disc disease, or injury.
Back pain is a common symptom characterized by discomfort or soreness in the back, often occurring in the lower region of the back (lumbago). It can range from a mild ache to a sharp stabbing or shooting pain, and it may be accompanied by stiffness, restricted mobility, and difficulty performing daily activities. Back pain is typically caused by strain or sprain to the muscles, ligaments, or spinal joints, but it can also result from degenerative conditions, disc herniation, spinal stenosis, osteoarthritis, or other medical issues affecting the spine. The severity and duration of back pain can vary widely, with some cases resolving on their own within a few days or weeks, while others may require medical treatment and rehabilitation.
X-ray computed tomography (CT or CAT scan) is a medical imaging method that uses computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of the body. These cross-sectional images can then be used to display detailed internal views of organs, bones, and soft tissues in the body.
The term "computed tomography" is used instead of "CT scan" or "CAT scan" because the machines take a series of X-ray measurements from different angles around the body and then use a computer to process these data to create detailed images of internal structures within the body.
CT scanning is a noninvasive, painless medical test that helps physicians diagnose and treat medical conditions. CT imaging provides detailed information about many types of tissue including lung, bone, soft tissue and blood vessels. CT examinations can be performed on every part of the body for a variety of reasons including diagnosis, surgical planning, and monitoring of therapeutic responses.
In computed tomography (CT), an X-ray source and detector rotate around the patient, measuring the X-ray attenuation at many different angles. A computer uses this data to construct a cross-sectional image by the process of reconstruction. This technique is called "tomography". The term "computed" refers to the use of a computer to reconstruct the images.
CT has become an important tool in medical imaging and diagnosis, allowing radiologists and other physicians to view detailed internal images of the body. It can help identify many different medical conditions including cancer, heart disease, lung nodules, liver tumors, and internal injuries from trauma. CT is also commonly used for guiding biopsies and other minimally invasive procedures.
In summary, X-ray computed tomography (CT or CAT scan) is a medical imaging technique that uses computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional images of the body. It provides detailed internal views of organs, bones, and soft tissues in the body, allowing physicians to diagnose and treat medical conditions.
Low back pain is a common musculoskeletal disorder characterized by discomfort or pain in the lower part of the back, typically between the costal margin (bottom of the ribcage) and the gluteal folds (buttocks). It can be caused by several factors including strain or sprain of the muscles or ligaments, disc herniation, spinal stenosis, osteoarthritis, or other degenerative conditions affecting the spine. The pain can range from a dull ache to a sharp stabbing sensation and may be accompanied by stiffness, limited mobility, and radiating pain down the legs in some cases. Low back pain is often described as acute (lasting less than 6 weeks), subacute (lasting between 6-12 weeks), or chronic (lasting more than 12 weeks).
The sacrum is a triangular-shaped bone in the lower portion of the human vertebral column, located between the lumbar spine and the coccyx (tailbone). It forms through the fusion of several vertebrae during fetal development. The sacrum's base articulates with the fifth lumbar vertebra, while its apex connects with the coccyx.
The sacrum plays an essential role in supporting the spine and transmitting weight from the upper body to the pelvis and lower limbs. It also serves as an attachment site for various muscles and ligaments. The sacral region is often a focus in medical and chiropractic treatments due to its importance in spinal stability, posture, and overall health.

- Symptoms of spondylolysis can include lower back pain that may radiate to the buttocks or legs, muscle spasms , and stiffness in the back. (osmosis.org)
Pediatric3
- The natural history of spondylolysis is unclear [ 9 ] and there is a lack of prospective comparative studies evaluating the effect of a rigid thoracolumbar orthosis compared with a soft brace on the healing of the defects of the pars interarticularis in pediatric population. (medscape.com)
- We also aimed to figure out factors that affect the bony union of pediatric spondylolysis. (medscape.com)

- Fifty-seven consecutive children with acute spondylolysis (mean age: 14.1 yr, range: 9-17 yr) were prospectively enrolled. (medscape.com)
- A rigid thoracolumbar orthosis did not provide any benefits over an elastic lumbar support in terms of bony union or HRQoL outcomes in children with acute spondylolysis. (medscape.com)
Bony union1
- Treatment outcomes included bony union of the spondylolysis assessed with a computed tomography at four months and HRQoL using the Scoliosis Research Society-24 outcome questionnaire filled out before and after the treatment. (medscape.com)
Incidence1
- When analyzing the specific spondylolysis subgroups, there were no significant differences in PI, but the multi_lysis group had a higher L5 incidence (p = 0.004), PT (p = 0.018), and PT/PI ratio (p = 0.039). (thejns.org)
Degeneration1
- Constant hyperextension can lead to developing extension based low back disorders, spondylolysis and degeneration over time. (bocatc.org)
Susceptible2
- It is believed that both repetitive trauma and an inherent genetic weakness can make an individual more susceptible to spondylolysis. (wikipedia.org)
- The enhanced anterior pelvic tilt is a very common movement pattern in extension-related sports such as ballet, gymnastics and tennis, making individuals in these sports more susceptible to the development of spondylolysis. (physio-pedia.com)
