Reconstruction of the trapezium with structural bone graft in trapeziometacarpal joint arthroplasty with cup instability.

Periprosthetic complications after trapeziometacarpal arthroplasty mostly require revision surgery to restore function. An unstable cup in the trapezium is typically surgically managed by trapeziectomy. This report highlights a possible alternative to maintain the implant by reconstruction of the trapezium with corticocancellous autograft.

Fully Threaded Versus Partially Threaded Intramedullary Headless Compression Screw Fixation for Proximal Third Fractures of the Proximal Phalanx: A Biomechanical Study.

Purpose: The purpose of this study was to compare the maximal elastic force and deformation resistance of two commonly used headless compression screw systems, a fully threaded 2.5 mm screw and a partially threaded screw of the same dimensions, in a cadaveric model of a human transverse proximal third fracture of the proximal phalanx.

Methods: Six fresh frozen cadavers were used, and the proximal phalanges of the index, long, and ring fingers of both hands were dissected.

Antegrade versus retrograde headless intramedullary compression screw fixation of diaphyseal proximal phalanx fractures: a biomechanical study.

This study compared antegrade and retrograde headless intramedullary compression screw fixation for fractures of the proximal third of the proximal phalanx. Antegrade fixation showed superior stability, provided more rigid fixation and preserved the smaller distal articular surface of the proximal phalanx.

Revision options for discontinued trapeziometacarpal arthroplasties: compatibility with currently available implants.

Surgical revision options for failed trapeziometacarpal total joint replacement include implant replacement and trapeziectomy. However, discontinuation of older implants complicates revision with original components, particularly as removing a well-fixed metacarpal stem can be challenging. This study examined the feasibility of pairing discontinued stems (Arpe, Elektra and Ivory) with currently available necks (Maïa, Moovis and Touch).

Ultrasound-guided trigger finger release with a minimally invasive knife: A retrospective analysis of 297 releases.

Trigger finger, or stenosing tenovaginitis, is a common condition characterized by impaired flexor tendon sliding due to thickening of the A1 pulley. While open surgical release remains the gold standard for the treatment of persistent trigger finger, there is increasing interest in minimally invasive ultrasound-guided techniques to improve precision and outcomes. The purpose of this study is to evaluate the outcomes, safety, and complications associated with ultrasound-guided trigger finger release using a minimally invasive surgical knife.
