title: Sesamoidectomy and volar plate repair using suture anchor for hyperextension injury of the metacarpophalangeal joint of the thumb.
abstract: A retrospective study for the combination of suture anchor and selective sesamoidectomy for treating volar instability of the metacarpophalangeal joint (MCPJ) of the thumb. Eleven patients with hyperextension of the MCPJ of the thumb underwent volar plate repair using a volar or voloradial approach. All the patients were reviewed radiologically and clinically using both objective and subjective criteria. The patients presented with sesamoid fractures (n = 2), sesamoid subluxation (n = 1), isolated volar plate laxity (n = 4), isolated sesamoid fracture (n = 4), and metacarpal condyle fracture (n = 2). The inner intersesamoid distance was 4.6 mm and the outer intersesamoid distance was 14.2 mm. The Disabilities of the Arm Shoulder and Hand and Michigan Hand Outcomes Questionnaire scores showed improvement. Volar plate repair using a suture anchor and selective sesamoidectomy is effective with regard to pain relief and stabilisation of volar instability of the thumb.
