A clinical study was undertaken to evaluate the pneumatic tourniquet setting required for adequate hemostasis in extremity surgery. After induction of anesthesia, the pneumatic tourniquet pressure at which the peripheral pulse disappeared was determined using a Doppler stethoscope. ⋯ Maximum pressures utilized were 255 mm Hg in the upper extremity and 305 mm Hg in the lower extremity. This simple, noninvasive technique uses tourniquet pressure settings well below those recommended in standard reference texts without sacrificing the adequacy of hemostasis to obtain a "bloodless field."

Case ReportsAvulsion fractures of the tibial tubercle in adolescents. A report of bilateral fractures and a review of the literature.
Avulsion fractures of the tibial tubercle prior to epiphyseal closure are being treated with greater frequency. Watson-Jones Types I and III fractures are the most common; both require open reduction and internal fixation. Type II fractures respond to closed reduction and plaster immobilization. ⋯ Type III fractures occurred most often in older adolescents. Types I and II fractures occurred in younger patients. No reports of growth disturbance of the proximal tibial epiphysis occurring after a Type III fracture were found.
