title: Treatment of chronic, traumatic hyperextension deformities of the proximal interphalangeal joint with flexor digitorum superficialis tenodesis.
abstract: OBJECTIVE
  To our knowledge, there are no reports in the literature regarding treatment of chronic, posttraumatic proximal interphalangeal (PIP) joint hyperextension deformities with flexor digitorum superficialis tenodesis. The purpose of this study was to describe the surgical treatment and results of flexor digitorum superficialis tenodesis for the treatment of chronic, posttraumatic PIP joint hyperextension deformities.
  
  
  METHODS
  Twelve patients were reviewed retrospectively and re-examined at a mean follow-up period of 35 months (range, 6-108 mo). Evaluation included completion of a Disabilities of the Arm, Shoulder, and Hand questionnaire and range of motion (ROM) measurements.
  
  
  RESULTS
  There were 5 excellent, 5 good, and 2 fair results. Five patients had a residual flexion contracture at the PIP joint of 5 degrees to 15 degrees, although this did not create any functional impairment as determined by responses to the Disabilities of the Arm, Shoulder, and Hand questionnaire at follow-up evaluation. The 2 patients with fair results had postoperative PIP flexion contractures of 30 degrees and 60 degrees. All 12 patients returned to their previous occupations and recreational activities.
  
  
  CONCLUSIONS
  Flexor digitorum superficialis tenodesis is an effective method with predictable results for the treatment of chronic, traumatic hyperextension deformities of the PIP joint.
