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.

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.

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.

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.
