Although falls are a major factor in the occurrence of femoral neck fractures, their type and frequency have not been studied in detail. A few case-reports have demonstrated that bone insufficiency can lead to femoral neck fracture and that some falls occur as a result of acute pain preceding the fracture. Estimations of the proportion of femoral neck fractures due to bone insufficiency have ranged from 3% to 24%. ⋯ Features associated with spontaneous fracture were pain during the preceding weeks (7/8; p<0.01), gradually worsening pain (6/7; p<0.02), pain in the inguinal or crural area (6/7), and recent onset of pain (< 3 months) (5/7). We believe that the incidence of bond insufficiency as a cause of femoral neck fracture has been substantially underestimated as a result of diagnostic difficulties and of the usually moderate severity of prefracture pain. Improved knowledge of prefracture symptoms provided by a prospective study may allow appropriate treatment by elimination of weight-bearing, avoiding a substantial number of femoral neck fractures.

Review Clinical Trial
When is spinal fusion warranted in degenerative lumbar spinal stenosis?
This study, conducted by a group of neurosurgeons who devote a large portion of their professional time to the treatment of degenerative lumbar spine lesions, was prompted by the dramatic increase in the number of lumbar spinal fusion procedures performed over the last few years in a broad spectrum of disorders ranging from chronic incapacitating low back pain to lumbar spinal stenosis. In the authors' experience, lumbar spinal fusion is rarely warranted and often of dubious efficacy. ⋯ Findings demonstrate that spinal fusion is a technique of unproven benefit that should be used only in carefully selected patients until results of reliable, prospective, comparative clinical trials become available. In the authors' opinion lumbar spinal fusion should be used as the first-line treatment only in young patients with clinical manifestations directly related to lumbar instability as defined in this study, when decompression requires removal of both facet joints and of the disk (which is rarely the case) or when simple decompression is followed by a recurrence of symptoms ascribable to worsening vertebral slippage.
