title: Surgical outcome of volar plate arthroplasty of the proximal interphalangeal joint using the Mitek micro GII suture anchor.
abstract: BACKGROUND
  The mechanism of injury in dorsal dislocation is usually a hyperextensive stress simultaneous with some degree of longitudinal compression. Operative treatment is indicated for those unstable and reduction is not achieved. We report the surgical outcome of volar plate arthroplasty of the proximal interphalangeal (PIP) joint using the Mitek Micro GII suture anchor.
  
  
  METHODS
  We reviewed the medical records of 20 patients with acute or chronic dorsal dislocation or subluxation of the PIP joint who were managed using the Mitek Micro GII suture anchor over the past 5 years by the same surgeon (J.T.S.). Fourteen patients had acute injuries (<4 weeks before surgery) and six patients had chronic injuries (average interval of 4.1 week from injury to surgery; range, 1-8 weeks). The patients had persistent pain and loss of range of motion after trauma, and the reductions were still unstable.
  
  
  RESULTS
  All patients were evaluated an average of 25 months postoperatively (range, 12-30 months). The average arc of motion of the PIP joints of the fingers was 82 degrees . There were no obvious perioperative complications, and no patient reported pain at rest or with activity.
  
  
  CONCLUSIONS
  Volar plate arthroplasty using the Mitek Micro GII suture anchor is an effective treatment choice for acute or chronic PIP joint dorsal dislocation or subluxation.
