Computer-assisted navigation for intramedullary nail fixation of intertrochanteric femur fractures: A randomized, controlled trial.

Introduction: Lag screw cutout is one of the most commonly reported complications following intramedullary nail fixation of intertrochanteric femur fractures. However, its occurrence can be minimized by a well-positioned implant, with a short Tip-to-Apex Distance (TAD). Computer-assisted navigation systems provide surgeons with the ability to track screw placement in real-time.

Short versus long intramedullary nails for treatment of intertrochanteric femur fractures (OTA 31-A1 and A2).

Objectives: The purpose of this study was to compare blood loss and operative times associated with long versus short intramedullary nails for intertrochanteric fracture fixation and rate of periprosthetic fracture.

Design: A retrospective study.

Setting: Level 1 trauma center.

Surgical treatment of displaced proximal humerus fractures with a short intramedullary nail.

Background: The Polaris nail is an intramedullary device for treating displaced proximal humerus fractures with few published studies to support its use. Results of a consecutive series of patients treated with the Polaris nail are presented.

Methods: Eighteen patients with a mean age of 71 years (range, 37-84) were treated for twelve 2- and six 3-part fractures.
