The segmental effect of Cotrel-Dubousset instrumentation (CDI) on the spine and thoracic cage was investigated in 38 patients with adolescent idiopathic scoliosis by preoperative and postoperative postero-anterior and lateral radiographs and computed tomography from T1 to S1. Mean Cobb angle decreased by 67%. The T5-T12 kyphosis in the hypokyphotic patients increased on average by 8.4 degrees (P < 0.001). ⋯ However, no correlation was found between flexibility index and reduction of RHi at the apex level. Vertebral derotation did not correlate with reduction in RHi at any level. The study shows that CDI results in a postoperative three-dimensional improvement of the spine and a limited improvement of the thoracic cage, with no tendency towards a worsened deformity at any level within or outside the instrumentation.

Chronic low back pain patients chosen for lumbar fusion surgery were entered into a prospective study with the aim of evaluating whether pre-operative pharmacological pain classification correlated with the outcome of surgical treatment. Twenty consecutive patients (mean age 39 years, range 29-50 years) with a mean pain duration of 4.6 years (range 1-8 years) participated. The patients' pain, disability and work situation were evaluated pre- and post-operatively. ⋯ In the group with non-responding pain surgical outcome was significantly poorer (P < 0.01), and was ranked as excellent/good in only one out of seven patients. There was a significant improvement (P < 0.05) concerning both pain and disability in the nociceptive group, but not in the non-responding group. Pre-operative pharmacological pain testing may be useful as a predictor of surgical outcome and we suggest that it can be employed as a means to identify patients with non-responding pain and poor surgical prognosis.

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.
