The purpose of this study was to determine the relationship between facet joint osteoarthritis and disc degeneration in subjects in whom both MRI and CT scans had been obtained. The MRI scans were used to determine disc degeneration, the CT scans to determine facet joint osteoarthritis. It was hypothesized that disc degeneration would sometimes occur(More)
Trunk strengths were measured in 27 health males and 30 health females, and in 25 male and 15 female patients with low-back pain and/or sciatica. Maximum voluntary isometric strengths were measured during attempted flexion, extension, and lateral bending from an upright standing position. Both male and female patients had approximately 60% of the absolute(More)
The results of postoperative epidural administration of saline solution (a placebo), morphine, methylprednisolone, and a combination of morphine and methylprednisolone for the reduction of pain after an operation for spinal stenosis or a herniated intervertebral disc were compared in a prospective, randomized blinded study. Epidural administration of(More)
Using data obtained by questionnaire in a retrospective review of patients with low-back and sciatic pain (eighty-five treated by injection of chymopapain and seventy-one, by open discectomy), the results at one and ten years after treatment were analyzed. For this analysis we used six measures of pain relief, six measures of the patients' course during the(More)
Twenty adolescent girls with mild-to-moderate cases of idiopathic scoliosis and twelve adolescent girls with structurally normal spines performed 15 exercises isometrically while standing. The exercises included resisting flexion, extension, and lateral bending moments imposed on the trunk. Myoelectric activities in 12 trunk muscle groups were measured(More)
This study examines the relation between the postchemonucleation clinical outcome and changes observed on the lumbar MR scan. Eight of 12 chemonucleated disks showed clinical improvement at the last follow-up, while the other four showed no improvement. In the cases that showed improvement there was a decrease in one or both dimensions of the defect in the(More)
Retrospectively 156 patients with an average follow-up period of 10.3 years were classified in two groups. Group I, 85 patients, chose chymopapain as their primary treatment. Group II, 71 patients, elected to have a laminectomy with discectomy. Overall, 98% of patients responded to follow-up investigations. Based on several well-accepted pain outcome(More)
Maximum voluntary isometric strengths of the trunk were measured in 93 girls who had mild idiopathic scoliosis and 109 girls who had structurally normal spines. Subject ages ranged from 10 to 16 years, and the mean Cobb measurement in the girls with scoliosis was approximately 22 degrees. Strengths were measured in attempted trunk flexion, attempted(More)
