A review of 40 consecutive nonreported multilevel lumbar fusions revealed an unacceptable pseudarthrosis rate of 32.5%. In an attempt to reduce this complication, a modification of segmental spinal instrumentation with use of a closed loop was performed on 50 consecutive patients treated by multilevel lumbar stabilizations. The primary diagnoses were(More)
Recent studies have shown that porous calcium phosphates provide a scaffold for bony ingrowth in various anatomic sites. In this preliminary investigation a type of porous calcium phosphate ceramic was implanted in the vertebral columns of 21 rabbits; the ceramic was studied as a possible bone graft substitute for use in spinal fusions. Animals were killed(More)
Planar bone scintigraphy (PBS) and single-photon emission computed tomography (SPECT) were compared in 19 adults with radiographic evidence of spondylolysis and/or spondylolisthesis. SPECT was more sensitive than PBS when used to identify symptomatic patients and sites of "painful" defects in the pars interarticularis. In addition, SPECT allowed more(More)
Twenty-six adult patients more than 6-months post-lumbar spinal fusion were studied. Flexion and extension radiographs showing motion or bone scintigrams showing focal areas of increased activity within the fusion mass were considered positive for pseudarthrosis. Patients were classified as either symptomatic or asymptomatic. Among the 15 symptomatic(More)
This study is a retrospective review of patients with pediatric laminoplasty. The objective was to determine the incidence of postlaminoplasty deformity. Long-term follow-up of patients with pediatric laminoplasty is lacking. Previous studies have shown spine deformity to be as high as 100% following laminectomy procedures. From 1986 until present, 31(More)
A long-term analysis of 106 patients who had lumbar fusions between 1959 and 1969 is reported. The method used in this series was an inlay bone graft pointed at each end and beveled at its cephalic portion to permit easier insertion. The sacroiliac ligaments are not disturbed while obtaining the bone graft and no sacroiliac complications have occurred. The(More)
The conditions and clinical significance of postlaminectomy spondylolisthesis were investigated in eight cases of lumbar spondylolisthesis, including five with slips not present at the time of decompression and three with progression of previously observed degenerative slips. All were women with an average age of 62 years. The major instability occurred at(More)
Seven patients with a malignant tumor were treated for spinal instability with Luque-rod fixation either with or without bone-grafting. The stabilization was successful in all patients, including five who died as a result of the tumor between six and eighteen months postoperatively. Two patients were still alive at an average of twenty-two months after(More)
The failure biomechanics of Harrington distraction rods, modified Weiss springs, and Luque rods were studied in intact cadavers and isolated spinal columns using flexion-compression loading. Most spines fractured at T-11 or T-12 at applied loads ranging between 556 and 4220 newtons (mean = 1833 N). After Harrington distraction rod placement, the same spines(More)
Traumatic fracture of the long bones of the lower extremities may frequently occur in spinal cord injured patients. In the past, conservative treatment with pillow or sand bag splinting was advocated by many clinicans. This paper presents two cases in which posterior splinting was used on the affected leg for stabilization of the fracture with good result(More)
