Randomized Controlled Trial Multicenter Study
Training femoral neck screw insertion skills to surgical trainees: computer-assisted surgery versus conventional fluoroscopic technique.
: Femoral neck fractures are among the most common orthopaedic injuries impacting the health care system. Surgical management of such fractures with cannulated screws is a commonly performed procedure. The acquisition of surgical skills necessary to perform this procedure typically involves learning on real patients with fluoroscopic guidance. This study attempts to determine if a novel computer-navigated training model improves the learning of this basic surgical skill. ⋯ The findings of this study suggest that computer navigation may be safely used to train surgical novices in a basic procedure. This model avoids using both live patients and harmful radiation without a compromise in the acquisition of a 3-dimensional technical skill.

The purpose of this study was to assess the impact of variations in angulation of clamp placement to hold syndesmotic reduction and how subsequent syndesmotic screw placement affects malreduction of the syndesmosis. We hypothesized that an anatomic syndesmosis reduction cannot be reliably achieved with a clamp alone; and, inaccurate placement of intraoperative clamps and trans-syndesmotic screws after reduction can malreduce the ankle syndesmosis. ⋯ Our study demonstrates that intraoperative clamping and fixation can cause statistically significant malreduction of the syndesmosis. This article should alert clinicians that clamp and screw placement can cause iatrogenic malreduction of the syndesmosis and make them aware that these dangers occur with specific clamp and screw angles in particular.

Supraspinatus tendon trauma may contribute to residual shoulder pain after nail fixation for proximal humeral fractures. Some have proposed a more medial starting point for humeral nail insertion to avoid cuff tendon footprint damage. We hypothesized that percutaneous nail insertion via Neviaser portal would not only be possible, but would avoid tendon trauma, while sacrificing articular cartilage. ⋯ Short, locked humeral nail insertion is possible in percutaneous fashion via Neviaser portal without tendon injury. However, successful insertion comes at the cost of articular cartilage damage.

Randomized Controlled Trial
Lidocaine analgesia for removal of wound vacuum-assisted closure dressings: a randomized double-blinded placebo-controlled trial.
Wound vacuum-assisted closure (VAC) is a technique used frequently by orthopedic surgeons to facilitate wound closure. Bedside VAC removal can be a source of great pain for patients, which we hypothesize can be decreased by topical lidocaine application. ⋯ Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.
