  • Pars Injection for Lumbar Spondylolysis
    Pars Injection for Lumbar Spondylolysis Issue 4: March 2016 Review date: February 2019 Following your recent investigations and consultation with your spinal surgeon, a possible cause for your symptoms may have been found. Your X-rays and / or scans have revealed that you have a lumbar spondylolysis. This is a stress fracture of the narrow bridge of bone between the facet joints (pars interarticularis) at the back of the spine, commonly called a pars defect. There may be a hereditary aspect to spondylolysis, for example an individual may be born with thin vertebral bone and therefore be vulnerable to this condition; or certain sports, such as gymnastics, weight lifting and football can put a great deal of stress on the bones through constantly over-stretching the spine. Either cause can result in a stress fracture on one or both sides of the vertebra (bone of the spine). Many people are not aware of their stress fracture or experience any problems but symptoms can occasionally occur including lower back pain, pain in the thighs and buttocks, stiffness, muscle tightness and tenderness. vertebra facet joint pars interarticularis sacrum spondylolysis (pars defect) intervertebral disc If the stress fracture weakens the bone so much that it is unable to maintain its proper position, the vertebra can start to shift out of place. This condition is called spondylolisthesis. Page 3 There is a forward slippage of one lumbar vertebra on the vertebra below it. The degree of spondylolisthesis may vary from mild to severe but if too much slippage occurs, the nerve roots can be stretched where they branch out of the spinal canal.

The treatment varies a sign of a more serious problem. Back pain may originate based on the degree of slippage. In mild cases, the patient is from the muscles, bones, or ligaments or even the mechanics managed similarly to a spondylolysis with rest and physical of how the back is moving. One of the most common causes therapy. In high grade spondylolisthesis, which is rare, of back pain in young athletes is spondylolysis. Spondylolysis referral to an orthopedic surgeon is needed. However, with is a stress fracture of a small bony segment in the back of the proper treatment, the majority of patients with spondylolysis lumbar spine called the pars interarticularis. It is thought to and spondylolisthesis are able to return to sport.

Therefore it is more common in sports where arching vertebra, so even after recovery physicians may obtain x-rays the back is routine like dance, diving, gymnastics, volleyball periodically to monitor them. and tennis. Typical signs and symptoms of a spondylolysis are chronic low back pain in the center or just off to the sides that begins without an injury and is worse with arching the back.

  • Spondylolysis & Spondylolisthesis
    SPONDYLOLYSIS & SPONDYLOLISTHESIS What is Spondylolysis? Your lower back is called your lumbar spine. It is made up of five bones called lumbar vertebrae. The vertebrae have two major parts, a solid part called the body and a bony ring through which the lower part of the spinal cord and nerves travel. Between the bodies of the vertebrae is a shock absorbing structure called the disc. Part of the ring of each vertebra, called the pars, touches the vertebra above it and the vertebrae below it. Spondylolysis is a condition where there is a break in one or both sides of the ring of a vertebra. This condition is also called pars defect or pars stress fracture. Spondylolisthesis is a condition in which a break in both sides of the ring allows the body of the vertebra to slip forward. Spondylolysis and spondylolisthesis most commonly occur at the fourth or fifth lumbar vertebrae How does it occur? Spondylolysis results from repetitive extension of the back (bending backward). This causes weakness in the rings of the lumbar vertebrae, eventuall leading to a break (fracture) in a ring. Less commonly, these conditions may result from an injury to the back. Some doctors believe that certain people are born with weak vertebral rings. Athletes most commonly troubled by spondylolysis or spondylolisthesis are gymnasts, dancers, and football players. What are the symptoms? You may have low back pain or spasms, or you may have no symptoms at all. You may have pain all the time or only from time to time. Spondylolysis or spondylolisthesis usually does not damage the nerves.

Department of Orthopaedic Surgery, Graduate School of Medicine, Chiba University, Chiba, JPN Corresponding author: Yasuchika Aoki, [email protected] Abstract Background: There is insufficient current information regarding the prognosis of patients with lumbar spondylolysis when bone union is not achieved. To examine the number, age, and surgically treated levels of patients with lumbar degenerative disease who underwent lumbar spine surgery, and to compare the results between patients with spondylolysis and without spondylolysis, a cross-sectional study was performed. Methods: Patients with degenerative lumbar disease who underwent lumbar spine surgery were retrospectively reviewed (n=354). The prevalence of spondylolysis was determined using CT images. Patients were divided into a spondylolysis group and a non-spondylolysis group, and the patients’ age, sex, and surgically treated levels were compared between the two groups. Results: The prevalence of lumbar spondylolysis in the 354 patients was 6.50% (23/354). The patients’ age was significantly lower in the spondylolysis group (54.2 ± 13.5 years) than in the non-spondylolysis group (63.8 ± 14.2).

Although co-occurrence of lumbar spondylolysis and disc herniation is common, it is very rare to observe that a nerve root anomaly accompanies these lesions. A 49-year-old male patient presented with sudden-onset right leg pain. Examinations revealed L5/S1 lumbar spondylolysis and disc herniation. At preoperative period, he was also diagnosed with lumbosacral root anomaly. Following discectomy and root decompression, stabilization was performed. The complaints of the patient diagnosed with lumbosacral root anomaly at intraoperative period were improved at postoperative period. It should be remembered that in patients
