Simultaneous Bilateral Quadriceps Tendon Rupture Secondary to Parathyroid Carcinoma: A Case Report.

Simultaneous bilateral quadriceps tendon ruptures are a rare occurrence commonly associated with a traumatic event or systemic disease. A 31-year-old man presented with simultaneous bilateral quadriceps tendon ruptures with associated hyperparathyroidism secondary to parathyroid carcinoma. The injury occurred after the patient attempted to lift a small wooden log from the ground.

Gap Balancing Throughout the Arc of Motion With Navigated TKA and a Novel Force-Controlled Distractor: A Review of the First 273 Cases.

Background: This study evaluated the ability to achieve the targeted soft-tissue balance in terms of medio-lateral (ML) laxity and gap values when using a computer-assisted orthopedic surgery (CAOS) system featuring an intra-articular force-controlled distractor and assessed learning curves associated with the adoption of this technology.

Methods: The first 273 cases using this technology were reported without exclusions comparing 1) final ML laxity and 2) final average gap to their predefined targets. For both parameters, the signed and unsigned differentials were reported.

Controversies in the management of distal radius fractures.

Controversies span the entire spectrum of management of distal radius fractures-fracture assessment, diagnosis, treatment, and evaluation of outcomes. The utility of multiple radiographic views described in the literature has not been validated. Likewise, the several classification systems that exist have yet to demonstrate substantial interobserver and intraobserver reliability.

Self-correcting intramedullary Kirschner wire fixation of metacarpal shaft fractures.

Metacarpal shaft fractures are commonly encountered by hand and upper extremity surgeons. The majority of these fractures may be treated nonoperatively. In cases of unstable or significantly displaced metacarpal shaft fractures, surgical intervention may be warranted.
