    Notes: Abstract Thirty-one consecutive patients with ankylosing spondylitis and spinal fractures were reviewed. There were 6 women and 25 men with a mean age of 60±11 years; 19 had cervical and 12 had thoracolumbar injuries. Of the patients with cervical fracture, two had an additional cervical fracture and one had an additional thoracic fracture. Three trauma mechanisms were identified: high-energy trauma in 13 patients, low-energy trauma in 13 and insufficiency fracture in 5. One-third of the patients suffered immediate neurological impairment, a further one-third developed neurological impairment before coming for treatment and only one-third remained intact. Two patients with thoracolumbar fractures had deteriorated neurologically due to displacements during surgery at other hospitals. All patients were treated operatively except the two patients with two-level cervical fractures, who were managed in halo vests. In the cervical spine both anterior and posterior approaches were employed. In the thoracolumbar spine the majority of the patients were initially treated using a posterior approach only. Complications were common. Of the 27 patients with neurological compromise, 10 had remained unchanged; 12 had improved one Frankel grade; 4 had improved by two Frankel grades; 1 had improved by four Frankel grades. We conclude that even minor trauma can cause fracture in an ankylosed spine. A high proportion of patients with spinal fractures and ankylosing spondylitis have neurological damage. The risk of late neurological deterioration is substantial. As the condition is very rare and the treatment is demanding and associated with a very high risk of complications, the treatment of these patients should be centralised in special spinal trauma units. A combined approach that stabilises the spine from both sides is probably beneficial.

    Notes: Summary The efficacy of ‘limited posterior surgery’ for metastases in the thoracic and lumbar spine was studied prospectively in 51 patients (32 men and 19 women, mean age 64 years). The most common primary tumors were prostate, breast, and renal carcinoma, 37 patients had metastases in the thoracic spine and 14 in the lumbar spine. Indications for surgery were severe pain or neurologic deficit. Of the 46 patients with neurologic symptoms, 25 were unable to walk. Surgery was confined to direct or indirect decompression and stabilization with a pedicle screw fixator over few segments as possible. Pain, as well as a variety of functional performance parameters and residential status were registered preoperatively and after surgery at 3, 6, 9, and 12 months, and at 6-monthly intervals thereafter. Pain was rated by the patient on a Visual Analog Scale, and functional performance was assessed with the Eastern Co-operative Oncology Group (ECOG) Performance Status Scale. We had no perioperative neurologic deterioration or death. Nineteen of the 25 nonambulatory patients regained their walking ability. Postoperative pain relief was significant and lasting over time. Nearly half of the patients attained improvement in functional performance. The median survival was 8 months. Older age and intact postoperative walking ability were positive factors for survival.
