title: Conservative treatment of stable volar plate injuries of the proximal interphalangeal joint in children and adolescents: a prospective study.
abstract: OBJECTIVE
  The purpose of this study was to assess a standard conservative management for stable volar plate injuries of the proximal interphalangeal joint in children and adolescents. No study is available regarding this subject for this age group.
  
  
  METHODS
  A prospective study was performed on 37 consecutive patients (aged between 9 and 15 years; mean, 13 years) with stable acute volar plate injuries of the proximal interphalangeal joints, including 22 avulsion fractures without dislocation. All patients had a standardized conservative treatment consisting of a dorsal aluminum extension block splinting at a 15-degree flexion for 10 days, followed by a spontaneous mobilization and taping to adjacent fingers for sports only. At follow-up visits, active and passive ranges of motion, swelling of the affected joints, analgesic intake, and pain perception by the patient were recorded. Regular follow-up consisted of standardized assessments at 2, 6, and 12 weeks, with additional consultations if symptoms persisted.
  
  
  RESULTS
  Healing was uneventful, and hand therapy was not necessary to regain full range of motion in 32 of 33 children with a regular follow-up. The only flexion contracture observed responded well to splinting. Of the 33 patients, 31 had an excellent outcome and 2 had a good outcome.
  
  
  CONCLUSIONS
  Dorsal extension block splinting was an efficient, simple, well-tolerated treatment for stable volar plate injuries of the proximal interphalangeal joint in a preliminary series of patients younger 16 years. Flexion contractures were rare and responded well to dynamic splinting.
