title: Volar capsulodesis of the thumb metacarpophalangeal joint at the time of basal joint arthroplasty: a surgical technique using suture anchors.
abstract: OBJECTIVE
  To document the long-term results of our volar metacarpophalangeal (MCP) joint capsulodesis technique that is completed concomitantly with basal joint arthroplasty and involves a suture anchor placement, short-term pinning, and a rigid hand therapy protocol.
  
  
  METHODS
  We conducted a retrospective chart review to examine results over a 30-month period of our volar capsulodesis technique. Follow-up results were recorded 26 to 48 months after surgery. The treatment regimen included suture anchors, joint pinning for 6 weeks, and a strict hand therapy protocol. Indications for surgery were thumb MCP joint hyperextension deformity of at least 30° and radiographic evidence of stage 3 (or greater) basal joint arthritis. We examined preoperative and postoperative range of motion, pain, pinch strength, and complications. Average patient age was 63 years (range, 55-77 y). We treated 14 thumbs in 14 patients.
  
  
  RESULTS
  After capsulodesis, average range of motion for the MCP joint of the thumb was 4° extension and 46° flexion. The last follow-up indicated no cases of hyperextension contracture. Complications included one superficial pin track infection (treated with oral antibiotics) and one patient's report of pain at the thumb MCP joint.
  
  
  CONCLUSIONS
  When completed as described, thumb MCP joint capsulodesis performed concurrently with trapeziometacarpal arthroplasty can be a straightforward procedure that produces positive results.
