To determine the effectiveness of exchange reamed nails for treatment of aseptic femoral delayed unions and nonunions. ⋯ Reevaluation of routine exchange nailing as the recommended treatment for aseptic femoral delayed union or nonunion may be required. A significant number of patients who undergo reamed exchange nailing will require additional procedures to achieve fracture healing.

To evaluate the results of radial head excision for the treatment of elbow fracture-dislocations with an unsalvageable comminuted radial head fracture and no other associated fractures. ⋯ Acute radial head excision for the treatment of elbow fracture-dislocations provides satisfactory short-term clinical results when there are no other associated intraarticular fractures. However, the long-term significance of the early degenerative changes is not known.

To assess the accuracy of a previously undescribed method of determining tibial nail length based on anatomic landmarks. ⋯ The tibial tubercle-medial distance (TMD) proved an easy, inexpensive, and accurate method of preoperative nail assessment.

To determine the optimal starting points for placement of S1 and S2 iliosacral screws as well as the pertinent anatomy surrounding the S1 and S2 vertebral bodies. ⋯ The iliosacral screw starting point at the posterior sacral body and inferior S1 foramen was the safest when considering the entire population. Careful attention to the size and orientation of the S2 vertebral body should be taken if S2 iliosacral screws are placed.

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.
