Closed, reamed, antegrade nailing remains the standard of care for femoral shaft fractures. This technique however, may be less attractive in the management of femoral shaft fractures associated with (a) ipsilateral acetabular, pelvis, or femoral neck fractures; (b) polytrauma requiring multiple simultaneous surgical procedures; and (c) pregnancy. We now report on our experience with the retrograde femoral nailing as a treatment option in these situations. ⋯ Knee flexion averaged 122 degrees; only two knees had an extensor lag of > 5 degrees. Intraoperative complications included three cases of crack propagation at the insertion site, and four infraisthmal malreductions (two valgus, two flexion). Based on these results, we feel that retrograde reamed femoral nailing is a suitable alternative to antegrade nailing and should be considered in situations where proximal access is neither possible nor desirable.

A retrospective review of all patients with femur fractures was performed to determine whether isolated femoral shaft fractures were associated with hypotensive shock. One hundred patients were identified who had either an isolated femoral shaft fracture (group F, 62 patients) or a femoral shaft fracture in addition to other non-shock producing fractures or minor injuries (group A, 38 patients). No patients in this study were in class III or IV (hypotensive) shock; however, 11% progressed from no shock to class I and 13% from class I to class II. ⋯ Mechanism of injury, although significant as an independent variable, was highly associated with the presence of additional fractures and so is not required in the joint model. Femur fractures alone or in combination with other minor injuries should not be considered the cause of hypotensive shock in the traumatized patient. In the traumatized patient who presents with a closed femoral shaft fracture and hypotension, an alternative source of hemorrhage should be sought.

Indirect reduction and percutaneous screw fixation were attempted in 20 displaced tibial plateau fractures in 20 patients. Closed, indirect reduction was successful in 18 fractures; two others, both Schatzker type II fractures, required open reduction. The 18 fractures were followed for an average of 16.2 months (range, 12-24 months). ⋯ Depressed fragments could not be reduced reliably with either ligamentotaxis or percutaneous elevation with a tamp. There was no correlation between radiographic reduction and clinical outcome. It did not matter whether two, three, or four screws were used to stabilize the fracture.

Thirty-four patients with ipsilateral fractures of the femur and tibia with intraarticular extension into the knee of at least one fracture were reviewed at an average follow-up of 38 months. Joint involvement was present in 22 (65%) femoral fractures and 23 (68%) tibial fractures. In 11 (32%) patients, both fractures were intraarticular. ⋯ Only eight (24%) patients had good or excellent results. Complications were frequent, with deep infections occurring in 11 (32%) extremities, leading to above-knee amputations in three (9%) patients. This subgroup of floating knee injuries appears to be associated with a higher degree of systemic trauma, a higher percentage of open injuries, and a much graver prognosis.

A retrospective study of 53 patients with isolated femur fractures was performed to evaluate blood loss and transfusion incidence. Patients with other long bone fractures, abdominal, chest, mediastinal, and vascular injuries were excluded. Twenty-one patients required transfusion during the initial hospitalization averaging 2.5 units PRBCs. ⋯ Fracture patterns, classified as high or low energy, were not found to correlate with pre- or intraoperative blood loss, incidence of transfusion, delay to surgery or duration of hospital stay. The estimated blood loss in the study group averaged 1,276 cc, stressing the significance of long bone fractures in trauma patients. Preoperative hemorrhage determined transfusion need in contrast to intraoperative blood loss.
