Case ReportsSimultaneous bilateral avulsion fracture of the tibial tuberosity. A case report.
Bilateral avulsion fracture of the tibial tuberosity is a rare injury. A 14-year-old male gymnast sustained simultaneous tibial tuberosity displaced fractures while attempting a forward flip. The recommended treatment was open reduction and internal fixation. Functional results were excellent one year after surgical treatment.

Comparative StudyHistologic and electrophysiologic changes following subepineurial hematoma induction in rat sciatic nerve.
The sciatic nerves of 34 rats were used to study the effects of intraneural, extrafascicular hematoma, exclusive of any other trauma. Electrodiagnostic, histologic, and electron microscopic techniques were used. The amount of nerve fiber damage was assessed using computerized planimetry. ⋯ Although there was a difference in the amount of nerve damage between the blood-injected and the hematoma-evacuated group (less damage), this difference was not statistically significant. These findings suggest that intraneural extrafascicular hematoma produces electrophysiologic and histologic evidence of axonal degeneration affecting nerve fibers in the vicinity of the hematoma. Early evacuation of the intraneural hematoma appears to slightly reduce the deleterious effects of the lesion.
