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.

We report on two children with tuberculosis of the craniocervical junction. Atlantoaxial instability was evident in both patients due to the destruction of the dens and the atlantoaxial ligaments. ⋯ Despite anti-tuberculosis treatment and immobilization, atlantoaxial instability was evident on flexion/extension views. Successful fusion of C1 and C2 was performed in both patients.

This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicular/epidural corticosteroid injection techniques in managing cervical radiculopathy. Over a 10 year period, between 1986 and 1995, a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study. There were 57 men (84%) and 11 women (16%) of average age 47 years (range 31-65 years). ⋯ Despite the fact that all 68 patients were potential surgical candidates, they all made a satisfactory recovery without the need for surgical intervention. Forty-eight patients (76%) did not experience any arm pain, and of the 15 patients (24%) who did, this improved from 10 to an average of 2 (range 1-4) on a 10-point pain scale. Thus, patients with cervical radiculopathy make a satisfactory recovery with serial periradicular/epidural corticosteroid injections without the need for surgical intervention.

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.

Between 1985 and 1990, 68 patients with cervical radiculopathy due to soft disc herniation were treated by anterior cervical discectomy without interbody fusion. Eleven patients were unavailable for follow-up examination. The mean follow-up was 23 months (range 12-54 months). ⋯ No neurologic deficits arose. One patient was reoperated and fused for intractable residual neck pain. We conclude that anterior cervical discectomy without interbody fusion is a simple, safe and effective procedure for patients with soft disc herniation.
