: A unique complication of using full-length intramedullary nails for pertrochanteric and subtrochanteric femur fractures is nail penetration of the anterior cortex at the distal end of the femur because of a mismatch of the anatomic femoral bow with that of currently available cephalomedullary nails (CMNs). This study was performed to determine the rate of distal femoral cortical penetration after stabilization of the proximal femur in a consecutive series of patients using a long CMN with a curvature of 180 cm and to examine the final location of the nails within the femoral canal. ⋯ : Therapeutic Level IV.

The aim was this study was to analyze the risk factors for reoperation after internal fixation of intertrochanteric fractures of the femur using the percutaneous compression plate (PCCP). ⋯ Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.

In contrast to open reduction internal fixation, percutaneous fixation is a relatively new option for operative fixation of acetabular fractures. The techniques for percutaneous insertion of anterior and posterior column screws have been previously described. For technical aspects of retrograde percutaneous posterior column screws, much attention has been paid to the proper start point. ⋯ Understanding of posterior column anatomy and its radiographic correlates are fundamental in the safe placement of this screw. Herein, we present technical advice for acquisition and interpretation of fluoroscopic images needed to ensure a safe trajectory and end point in retrograde percutaneous posterior column screw placement. We highlight our steps to ensure correct placement in a small series.

Diagnosis of femoral neck fracture associated with femoral shaft fracture: blinded comparison of computed tomography and plain radiography.
Femoral neck fractures that are associated with femoral shaft fractures have historically been associated with high rates of missed diagnosis. Despite the potentially serious consequences of a missed femoral neck fracture, little work has been conducted to rigorously evaluate the ability of commonly used imaging studies to detect such fractures. Our hypothesis was that axial-view computed tomography is superior to plain radiography at detecting femoral neck fractures. ⋯ Plain radiography and computed tomography have rates of missed femoral neck fractures that are similar and substantial, with a sensitivity of only 56%-64%. Our data emphasize the importance of intraoperative and postoperative imaging in detecting nondisplaced femoral neck fractures in association with femoral shaft fractures.

To compare implant positioning in the distal femur between 2 cohorts of elderly patients treated for a hip fracture with a long 200- or 150-cm radius of curvature (ROC) cephalomedullary nail. We theorized that the 150-cm ROC nails would more closely approximate the femoral bow and result in fewer implant-related complications. ⋯ Therapeutic Level III.
