Lumbar spine surgery and mortality among Medicare beneficiaries, 1986.

OBJECTIVES: The purpose of this study was to compare lumbar spine surgical procedures by age, gender, and number of comorbidities with respect to mortality in patients 65 years of age and older in the United States. METHODS: A 100% sample of the 1986 Medicare inpatient Health Care Financing Administration claims files databases involving lumbar spine surgical procedures was analyzed. RESULTS: Lumbar spine surgery in 34,418 patients (median age = 71 years) was associated with a significant increase in in-hospital and 1-year cumulative mortality only beyond 80 years of age. When adjusted for age, in-hospital and 1-year cumulative mortality with both decompression and excision procedures were significantly higher in men than in women. When adjusted for both age and gender, mortality increased significantly as the number of comorbidities increased. CONCLUSIONS: With lumbar spine surgery in elderly patients, mortality did not significantly increase until 80 years of age and was consistently associated with decompression and excision, with male gender, and with an increase in number of comorbidities.

The effects of motion on the healing of cancellous bone.

In 20 dogs olecranon osteotomies fixed with tension band wires were studied histologically to reveal the pattern of healing. Different degrees of stability existed in different areas of the osteotomy. Under stable conditions cancellous bone healed by direct formation of woven bone. Instability resulted in an internal cartilaginous callus. Once stability was restored, the callus underwent endochondral ossification. The articular defect, which was in an area of maximum instability, healed by fibrocartilage.

Thoracic facetectomy and bone grafting in the surgical treatment of adult idiopathic scoliosis.

A retrospective study of adult patients with surgically treated idiopathic scoliosis was carried out to determine the importance of thoracic facetectomy and bone grafting. The results indicate that failure to excise and bone graft the thoracic facets was not associated with a significant impairment of initial correction or loss of correction after a mean follow-up of 2 years. The incidence of pseudarthrosis was comparable to other series. It also was established that the use of Bobechko hooks without postoperative bracing gave satisfactory results.

Laparoscopically assisted spinal surgery.

BACKGROUND: Spinal surgery is one of the newest frontiers of videolaparoscopic surgery, but requires the cooperative efforts of both the spinal surgeon and the laparoscopic general surgeon. DATA BASE: We report our experience with 76 cases of laparoscopic spinal surgery, using both a transperitoneal and a retroperitoneal approach. Technical details and complications are described in detail. CONCLUSIONS: Fifty-one patients had a transperitoneal approach with an average operating time of 117 minutes. Uncomplicated cases stayed 4.4 days. Five patients required conversion. All but one patient had L5-S1 level surgery. Twenty-five patients had a retroperitoneal approach with 150 minutes operating time and a 5.7 day stay. Conversions were minimized with a two-balloon technique. The retroperitoneal approach allows for multiple level surgery with virtually unlimited fusion devices. Laparoscopically assisted spine surgery affords all the benefits of minimally invasive surgery, without limitations for the spinal surgeon.
