Spinal stenosis and posterior lumbar interbody fusion.

One hundred forty-two patients with the common types of spinal stenosis were treated by posterior lumbar interbody fusion (PLIF). The majority of the patients had one or more decompressive procedures prior to PLIF. The results were excellent or good in 78%. A review of the literature concerning long-term results of decompressive procedures indicates a short-term failure rate of 15%-20% and about 50% failure by ten or more years after the operation. Anterior fusion in primary disc lesions produces admirable results but is of little value in spinal stenosis. Long-term reports of the success rates of posterior lumbar interbody fusion indicate that this operation combines the success rate of an anterior interbody fusion with the benefits of posterior decompression.

Posterior intervertebral body fusion. A 25-year study.

The benefits derived from intervertebral body fusion using a posterior surgical approach were studied in 500 patients. The cases were reviewed during a 25-year period, with an average follow-up period of more than five years. Only eight patients did not return for adequate postoperative evaluation. Seventy-five percent of patients underwent primary excision of the disc with fusion, 11% had spondylolisthesis defects, and in 19% a second operation was performed after prior excision of the disc had failed. Discography provided the most reliable diagnostic procedure after physical examination. Disc degeneration and protrusion occurred 1 1/2 times more often in the fourth than in the fifth disc. Fusion occurred in 90% of patients. Eighty-two percent of patients rated the end result as excellent or good. Two blocks of autogenous bone from the ilium were used in all cases to produce the fusion. The surgical procedure and the complications that occurred are described.

The intramedullary compression rod.

The Kaessmann compression device was employed in 26 patients with fractures of the long bones. In 15 fractures of the tibia, prompt healing occurred, even in fractures in the distal one-fourth of the tibia. Most of these cases were treated without external plaster support, and were permitted early ambulation, with partial weight-bearing. The technique for immobilizing these fractures involves a sliding a Kuntscher nail over a tension rod, and then fixing the clevis of the tension rod to the distal bone fragments by a transverse screw. The Kuntscher nail is fixed to the proximal bone fragment by a metal lip, and after compression is achieved, a locking sleeve fixed by a screw to the tension rod, prevents loss of compression. In 11 cases of pseudarthrosis of the tibia, the medullary canal was enlarged by passing graduated drills down the bony canal, over a guide wire. The compression rod was then inserted across the pseudarthrosis, and seventy to 80 kg/cm2 pressure was applied to the bone ends. No bone grafting procedure was performed. In all 11 cases, prompt union occurred. Postoperative management was similar to that employed in the treatment of fresh fractures. Three success fusions of the ankle also attest to the effectiveness of this immobilization. Although controversy exists regarding the role of compression in the healing of fractures, the axial compression rod does overcome distraction, compresses the bony surfaces, immobilizing them securely to produce union with an economy of callus.
