A Novel Technique With Buttress Plating for Comminuted Base Fractures of the Proximal Phalanx.
Ann Plast Surg

Department of Orthopaedic Surgery, Duson Hospital, Ansan, Korea.
Background: Extra-articular but severely comminuted distal basal fractures of the proximal phalanx (PP) are rarely reported. Therefore, the aim of this study was to achieve proper union and desirable outcomes using low-profile locking plates/screws. We introduced our own surgical approach and reported the clinical/radiographic outcomes via retrospective case series.

This review provides a detailed analysis of the anatomy, mechanisms, and management of ligamentous and capsular injuries in metacarpophalangeal joints (MCPJs). The MCPJ is a condyloid joint with unique anatomical features, including a sagittal cam effect that enhances stability in flexion. Ligaments, tendons, and joint capsules contribute to the overall stability and mobility of MCPJs.

Article Synopsis
- A case of a thumb MCP joint dislocation was complicated by the interposition of sesamoid bones, leading to a condition known as "locked thumb" syndrome.
- The sesamoid bones became trapped at the base of the dislocated proximal phalanx, obstructing the typical reduction procedure.
- As a result of this blockage, closed reduction attempts were unsuccessful, necessitating surgical intervention.

The joints of the fingers play an important role in prehension. They must accomplish both great mobility in the sagittal plane to allow the fingers to roll up and great stability to ensure the grip is both precise and firm. The collateral ligaments and palmar plates are the main passive stabilizing structures between the interphalangeal (IP) and metacarpophalangeal (MCP) joints.

Department of Orthopaedic Surgery, Gifu University Graduate School of Medicine, Gifu, Japan.
Background: Both arthrodesis and trapeziectomy with ligament reconstruction and tendon interposition (T + LRTI) arthroplasty are reliable surgical procedures for thumb carpometacarpal (CMC) osteoarthritis. Here, we compared surgical outcomes between arthrodesis and T + LRTI for female workers aged over 40 years with thumb CMC osteoarthritis to determine an optimal procedure.
Patients And Methods: Fourteen thumbs of 13 patients who underwent arthrodesis with locking plates and 11 thumbs of 10 patients who underwent T + LRTI and were followed up for at least 12 months were retrospectively analyzed.
