Case ReportsUse of radionuclide method in preoperative and intraoperative diagnosis of osteoid osteoma of the spine. Case report.
A 24-year-old man with persistent low back pain and right sciatica, was found to have an osteoid osteoma of the right pedicle of the second lumbar vertebra. 99mTc-MDP bone scan and CAT scan produced an early diagnosis of the lesion. Intraoperative 99mTc-MDP in vitro combined with imaging and quantitative activity measurements were useful for accurate localization and complete removal. The method is simple and can be performed in every nuclear medicine department, with no need for special operating room facilities.

Case ReportsThe treatment of severe scoliosis in osteogenesis imperfecta. Case report.
Surgical stabilization of the scoliotic spine in osteogenesis imperfecta (OI) is technically difficult owing to the mechanical weakness of the bone. Brittle bone makes instrumentation of the spine a procedure all too often associated with complications. Combining the instrumentation of the OI spine, both anteriorly and posteriorly, with the use of methylmethacrylate to augment the fixation may prove valuable as a surgical technique. This usage of methylmethacrylate in correcting severe scoliosis in OI has not been previously reported.

To investigate whether effort-related dorsal forearm pain could be due to an increase of the intracompartmental pressure (ICP) in the dorsal forearm compartment, the normal range of the ICP at rest and during exercise was first determined in 11 volunteers using a wick catheter. The ICP at rest was 6 mm Hg (range, 2-11 mm Hg), and during exercise the pressure rose to about six times the resting level. ⋯ In six patients the pressure at rest and/or during exercise was more than twice that of the normal persons or that of the healthy forearm. After fasciotomy four of these six patients were relieved of pain within three weeks, which might suggest a relation between ICP and pain.
