Fracture-dislocation of the Dorsal-lumbar Spine. Acute Operative Stabilization by Harrington Instrumentation

Twenty-four patients (of whom 17 were paraplegic) with acute fracture dislocations of the dorsal-lumbar spine underwent stabilization with Harrington instrumentation and were followed for an average of 16 months. Immediate postoperative ambulation was achieved in 16 patients. There was little difference between compression and distraction with respect to reduction and maintenance of correction. Compression rods resulted in solid union in 15 of 16 patients, while distraction rods were successful in 6 of 8 instances. In contrast to reported series in which operative intervention has been avoided, at least a 50% reduction in total hospitalization stay and costs has been achieved. Functional results were comparable to or exceeded the results of other series, and complication rates were similar with the exception of postoperative pain in 2 patients.
