Relationship between rates and outcomes of operative treatment for lumbar disc herniation and spinal stenosis.
Population-based variations in rates of operations for the treatment of lumbar disc herniation and spinal stenosis are well known. This variability may occur in part because of differences in the threshold at which physicians recommend an operation, reflecting uncertainty about the optimum use of an operative procedure. To the best of our knowledge, no previous reports have indicated whether differences in population-based rates of operative treatment are associated with patient outcomes. ⋯ Higher population-based rates of elective spinal operations may be associated with inferior outcomes. This variability is possibly related to differences in physicians' preferences with regard to recommending an operation and in their criteria for the selection of patients. Physicians cannot assume that their outcomes will be the same as those of others, and therefore they need to evaluate their own results.

Treatment of giant-cell tumors of long bones with curettage and bone-grafting.
The use of curettage, phenol, and cement is accepted by most experts as the best treatment for giant-cell tumor of bone. The present study was performed to evaluate whether equivalent results could be obtained with curettage with use of a high-speed burr and reconstruction of the resulting defect with autogenous bone graft with or without allograft bone. ⋯ Despite the high rates of recurrence reported in the literature after treatment of giant-cell tumor with curettage and bone-grafting, the results of the present study suggest that the risk of local recurrence after curettage with a high-speed burr and reconstruction with autogenous graft with or without allograft bone is similar to that observed after use of cement and other adjuvant treatment. It is likely that the adequacy of the removal of the tumor rather than the use of adjuvant modalities is what determines the risk of recurrence.

Osteonecrosis of the femoral head associated with pregnancy. A preliminary report.
Osteonecrosis is usually associated with trauma, use of corticosteroids, or alcohol abuse. We investigated the rare association of osteonecrosis of the femoral head and pregnancy, and we defined differences between the disorder in pregnant women and that in women of childbearing age who were not pregnant. The results of treatment with a free vascularized fibular graft were evaluated in terms of relief of pain and improvement of the Harris hip score after a minimum of two years of follow-up. ⋯ Occasionally, pain in the hip that begins during pregnancy is caused by osteonecrosis of the femoral head. A high index of suspicion and use of magnetic resonance imaging may lead to an earlier diagnosis and a better prognosis in this population of women. In this study, treatment with a free vascularized fibular graft was a useful option with which to obviate or postpone the need for total hip arthroplasty.
