Thoracolumbar burst fractures treated with combined anterior and posterior surgery.

Between 1985 and 1992, 84 burst fractures were surgically managed with anterior decompression, autologous iliac crest strut graft, and posterior instrumentation and fusion. Fifteen were lost to follow-up, leaving 69 patients for detailed review. Of the 22 patients with complete or partial neurologic injury, 12 patients either totally or partially recovered function following surgery. Of these 12 patients, 6 improved 1 Frankel grade; 5 improved 2 Frankel grades, and 1 improved 3 Frankel grades. Follow-up was 12 to 91 months (average 41 months). For all of the fractures in this series, the mean operative correction in sagittal kyphosis was 14 degrees, but this decreased to 7 degrees at final review. No patient had significant scoliosis, and 66 patients achieved solid arthrodesis with 3 pseudoarthroses (4%). Mean operative time for 2-in-1 procedures was 5 hours 42 minutes, with an estimated blood loss of 1,455 mL. Of 62 patients available for follow-up telephone interview, 42 (68%) had minimal or no pain; 11, mild pain; 8, moderate pain; and 1, severe pain. Function in daily activities was assessed as normal or minimally impaired in 43 of 51 patients (84%) with normal neurologic function by physical examination. We conclude that anterior decompression, strut autografting, and posterior instrumented autogenous fusion, either as a combined or staged procedure, is a safe surgical option for thoracolumbar burst fractures.

Deterioration of operative correction in dystrophic spinal neurofibromatosis.

STUDY DESIGN: Of 28 patients with dystrophic spinal deformity resulting from neurofibromatosis who were treated surgically since 1968, 25 were studied regarding the outcome of spinal deformity at a mean follow-up of 9.7 years after surgery (mean age at follow-up, 21.5 years). OBJECTIVES: This study sought factors that contribute to curve deterioration despite successful spinal fusion for dystrophic spinal deformity in patients with neurofibromatosis. SUMMARY OF BACKGROUND DATA/METHODS: All patients had the following radiographs: standing anteroposterior and lateral, lateral bending, flexion and extension views of the spine, and radiographs of both tibiae. Patients who had large peripheral neurofibromata or evidence of long-bone deformity at other sites had radiographs of these anatomic regions. Spinal radiographs obtained pre-operatively, 6-12 months post-operatively, and at final follow-up were measured for spinal curvatures, vertebral height, and vertebral and disc wedging. RESULTS: For analysis, the patients were divided into three groups according to deformity: 1) scoliosis, 2) ky-phoscoliosis (with kyphosis > 50 degrees) and 3) hyperkyphosis (with kyphosis > 50 degrees and sharply angulated over three vertebrae). Mean deterioration was: scoliotic group, 12 degrees (range, 0 degree-52 degrees); kyphoscoliotic group, 7 degrees (range, 0 degree-35 degrees); hyperkyphosis group, 38 degrees (range, 20 degrees-60 degrees). All patients in the latter group had anterior and posterior spinal fusion. CONCLUSION: Spinal deformity in these patients tended to progress despite the achievement of spine arthrodesis in those with hyperkyphosis and short curves. The study shows that vertebral subluxation, disc wedging, and peripheral skeletal dystrophy are additional prognostic features that predict the progression of deformity after arthrodesis of the spine.

Resection for symptomatic talocalcaneal coalition.

Over a nine-year period, 20 feet with persistently symptomatic talocalcaneal coalition were treated by resection of the bar. The 17 patients were all under 16 years of age. Excellent or good long-term results were achieved in the ten feet in which preoperative coronal CT had shown that the area of coalition measured 50% or less of the area of the posterior facet of the calcaneum. In these feet heel valgus was less than 16 degrees and there were no radiographic signs of arthritis of the posterior talocalcaneal joint. Talar beaking was present in 70% of these feet but it did not impair the clinical result. Fair or poor results were observed in the ten feet in which preoperative CT had shown the area of relative coalition to be greater than 50%. In these feet, heel valgus was greater than 16 degrees and most had narrowing of the posterior talocalcaneal joint and impingement of the lateral process of the talus on the calcaneum.

Oesophageal perforation--a review of 37 cases.

We have reviewed 37 cases of ruptured oesophagus treated at St Vincent's Hospital from 1976 to 1986. Their age ranged from 20 to 89 years (mean 64 years) and 59% were female. The causes of rupture were spontaneous (9), foreign body (5), diagnostic oesophagoscopy (8), oesophagoscopy and dilatation (5), balloon dilatation (3), palliative intubation (6) and patient self dilation (1). Eighty-six per cent of perforations occurred in the lower third of the oesophagus. The most common means of diagnosis was a positive contrast swallow (90%) and/or the presence of cervical or mediastinal air (49%). Eighteen patients underwent surgical treatment which consisted of a combination of thoracotomy, drainage and repair, or laparotomy and Celestin tube insertion, with or without chest drainage. Two patients underwent oesophageal diversion. The overall mortality in all patients was 30% (37% non-operative and 22% operative group). We conclude that the management of ruptured oesophagus demands an individual approach depending upon the site and aetiology of perforation and the underlying disease. The condition is a disease of the elderly and continues to have a high morbidity and mortality.
