Injuries of the UCL occur when the extended thumb is bent radially away from the hand at the MCP joint. Common causes include a fall onto an outstretched hand, gripping the steering wheel during a car accident, and falling ...
Fusion of the MCP joint involved placement of longitudinal K-wires and tension band wiring. The patient underwent an initial right-sided procedure in 2008 and subsequently elected for the same procedure on the contralateral side 26 months later. Good functional improvement was achieved with a pre ...
Thumb boutonniere deformity occurs from MCP joint synovitis, leading to attenuation of extensor pollicis brevis (EPB), which inserts at the proximal phalanx. Similarly, the distension of the MCP joint stretches the extensor hood and causes volar subluxation of the extensor pollicis longus (EPL) ...
These include refashioning of the ligament from capsular remnants, dynamic tendon transfers, tendon advancement, free tendon grafts, and MCP joint fusion. Free tendon grafts offer a reliable method of reconstruction. Fixation is usually achieved by passing sutures through drill holes, using pull out ...
Arthrodesis of the thumb metacarpophalangeal (MCP) joint usually leads to satisfying results when performed with an open technique. The main complication is adhesion of the extensor tendons that sometimes requires hardware removal associated with tenolysis. The goal of this study was to assess ...
We describe a novel combination of a volar plate advancement and abductor pollicis brevis tenodesis to address MCP1 hyperextension at the time of CMC1 arthroplasty as an alternative to joint fusion. In 6 women, mean MCP1 hyperextension with pinch before surgery was 450 (...
