Review Case Reports
Urinary bladder dysfunction following anterior lumbosacral spine fusion: case report and review of the literature.
A 34-year-old woman suffering from chronic degenerative low back pain involving L5-S1 disc space, refractory to conservative treatment, underwent spinal fusion. A combined instrumented posterolateral, followed by anterior, interbody allograft fusion through a left retroperitoneal approach was performed. Postoperatively, the patient was unable to evacuate her bladder and control her micturition. ⋯ A self-catheterisation regime was instituted with a diagnosis of parasympathetic nerve injury during the anterior spinal fusion. After a period of 3 months, the patient regained control of urination. We report this case to highlight the importance of protecting the parasympathetic presacral nerve during L5-S1 anterior interbody fusion, as injury to this nerve affects urinary evacuation.

Chronic contained rupture of an abdominal aortic aneurysm is rare. These aneurysms are small and affected patients are usually normotensive. ⋯ Diagnosis is often delayed as the condition may present with symptoms referable to the lumbar spine. This report is of two cases where the initial diagnosis was infective spondylitis.

Failed back surgery syndrome (FBSS) is the presence of persistent, disabling pain in the hip, thigh, leg, or lower back of a patient who has undergone a laminectomy or discectomy. Some degree of FBSS is found in approximately 15% of such patients. There may be a direct relationship between the extent of pathology found during the initial surgical procedure and the probability that FBSS will develop. ⋯ In an attempt to inhibit peridural fibrosis, methylprednisolone, polyethylene films, and fat grafts have been applied to the dura after discectomy. These experimental treatments have had limited success. Development of a therapy that reliably prevents peridural adhesive fibrosis will reduce the incidence of FBSS.

Previous experimental studies have shown the effects of acute compression of the spinal cord and peripheral nerve roots. Recently, however, a few studies of chronic compression of the cauda equina in animal models have been reported. The purpose of this study was to determine the long-term electrophysiologic changes resulting from chronic compression of the cauda equina in dogs. ⋯ Dogs in which motor and sensory evoked potentials recovered also showed gradual disappearance of neurologic symptoms and signs. Recovery of motor evoked potentials in particular was associated with complete disappearance of neurologic symptoms and signs. For accurate prognosis in cases of chronic cauda equina compression, a combined diagnostic study of sensory and motor evoked potentials is recommended.

Little is known about the influence of high-performance training on the bone quality of the lumbar spine, in particular, the effects on bone mineral density (BMD) in athletes with high weight-bearing demands on the spine. Measurements were therefore performed in internationally top-ranked high-performance athletes of different disciplines (weight lifters, boxers, and endurance-cyclists). The measurements were carried out by dual-energy X-ray absorptiometry, and the results compared with the measurements of 21 age-matched male controls. ⋯ The results show that training program stressing axial loads of the skeleton may lead to a significant increase of BMD in the lumbar spine of young individuals. Other authors' findings that the BMD of endurance athletes may decrease are confirmed. Nevertheless the 10% BMD loss of cyclists was surprisingly high.
