Abstract
OBJECTIVES: 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.
