To determine the effects of ipsilateral hip and knee position on intraneural sciatic nerve pressures. ⋯ Intraneural sciatic nerve pressures are influenced by the position of the ipsilateral hip and knee. The magnitude of the pressure elevation appears to be related to the excursion of the nerve as the linear distance between the greater sciatic notch and the distal aspect of the leg increases. Intraneural tissue fluid pressures measured within a localized section of the sciatic nerve appeared to exceed published critical thresholds for alterations of blood flow and neural function only when the hip was flexed to 90 degrees and the knee was fully extended.

Coronal fractures of the femoral condyle (Hoffa fractures) are intraarticular fractures that are commonly treated surgically by open reduction and internal fixation. Surgical fixation is demanding because anatomic reduction is mandatory and adequate exposure is often difficult. Herein we describe a new technique that permits excellent visualization and fixation of lateral Hoffa fractures based on osteotomy of Gerdy's tubercle and reflection of the attached iliotibial band.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective, randomized study of intramedullary nails inserted with and without reaming for the treatment of open and closed fractures of the tibial shaft.
To determine if there are differences in healing, complications, or number of procedures required to obtain union among open and closed tibia fractures treated with intramedullary (IM) nails inserted with and without reaming. ⋯ Our findings support the use of reamed insertion of IM nails for the treatment of closed tibia fractures, which led to earlier time to union without increased complications. In addition, canal reaming did not increase the risk of complications in open tibia fractures.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized prospective study of humeral shaft fracture fixation: intramedullary nails versus plates.
To compare the clinical and radiographic results for locked intramedullary (IM) nails and plates used in the treatment of humeral diaphyseal fractures. ⋯ For patients requiring surgical treatment of a humeral shaft fracture, intramedullary nailing and compression plating both provide predictable methods for achieving fracture stabilization and ultimate healing.

Fracture of the radial head with associated elbow dislocation: results of treatment using a floating radial head prosthesis.
To assess elbow function, complications, and problems of radial head fractures associated with elbow dislocation receiving surgical treatment with a floating prosthesis. ⋯ The basic principle of maintaining anatomic and physiologic relationships applies when deciding on treatment for radial head fractures with associated elbow dislocation. The loss of lateral osseous support will render the elbow grossly unstable. We believe that a floating prosthesis may be indicated in Mason Type III radial head fractures associated with elbow dislocation, especially in the presence of associated destabilizing fractures. Well-controlled comparative randomized studies will be needed to delineate the optimal treatment for a given situation.
