Use of Electrocautery to Facilitate Suture Passage Through the Greater Trochanter of the Femur: A Biomechanical Study.

Introduction: The specific aims of this study were to evaluate (1) the axial force reduction of suture passage utilizing electrocautery when applied to the greater trochanter of the femur, (2) the temperature change caused while using electrocautery for suture passage, and (3) the failure loads and failure modes utilizing this technique.

Methods: Five matched pairs of fresh-frozen femurs were used and classified into two groups: with electrocautery on needle (study group) and without electrocautery on needle (control group). Two bicortical, osseous tunnels were made around the insertion of the gluteus medius tendon.

Use of electrocautery devices for suture passage through the greater tuberosity: a biomechanical study.

Background: The use of electrocautery to facilitate passage of a suture needle through bone without the aid of a drill or burr is a novel technique that has potential utility in orthopedic procedures, but there is a scarcity of research to support its utility. The specific aims of this cadaveric biomechanical study were to evaluate (1) the axial force reduction during suture passage using electrocautery when applied to rotator cuff repair, (2) the temperature change caused while using electrocautery, and (3) the failure loads and failure modes of this technique.

Methods: Five matched pairs of fresh frozen humeri were used, classified into 2 groups: with electrocautery on needle (study group) and without electrocautery on needle (control group).

Stability of Surgical Rib Fixation Hardware after Repeat Chest Trauma.

Surgical management of rib fractures has long been a controversial topic, but improvements in rib plating technology have led to a recent increase in interest among surgeons. Unfortunately, follow-up data are limited in patients following rib fracture plating. We present a unique case of an adult male who had multiple ribs plated for symptomatic rib fracture nonunions and developed periprosthetic fractures following repeat trauma several months later.

A Mini-Open, Dorsal Approach for Scaphoid Fracture Fixation With a Ligament Sparing Arthrotomy.

There are several surgical approaches that are currently used to address nondisplaced scaphoid waist fractures, including percutaneous fixation, limited exposure fixation, and traditional open techniques through a volar or dorsal approach. Although percutaneous fixation has some theoretical advantages, it is much more difficult to achieve an accurate starting point for a headless compression screw. The purpose of this paper is to describe a simple, dorsal, mini-open approach to the scaphoid that minimizes incision size, extensor tendon dissection, capsular trauma, and vascular disruption, while still allowing for direct visualization of the proximal pole and optimal exposure for accurate screw placement.

Radiographic Assessment of First Tarsometatarsal Joint Shape and Orientation.

Background: Hypermobility within the first tarsometatarsal (TMT) joint is a predisposing factor for hallux valgus. The purpose of this study was to assess whether the shape and angulation of the first TMT joint are affected by the positioning of the foot in radiographs.

Methods: Ten adult above-knee fresh-frozen cadaveric specimens were placed into a radiolucent apparatus that allowed controlled angulation of each foot at 0, 5, 10, 15, and 20 degrees in dorsiflexion, plantarflexion, inversion, and eversion.
