[Camptodactyly].

Camptodactyly is a permanent, nontraumatic flexion of the proximal interphalangeal joint. The prevalence is around 1% and the little finger is most commonly affected. Two groups may be identified, depending on the age of onset: camptodactyly severe within 2-3 years or beginning in the early teens. Many anatomical abnormalities have been incriminated as the cause of camptodactyly: anomalous lumbrical muscle, short flexor digitorum superficialis, retractile subcutaneous tissue, anomalous extensor muscle. Splinting is always required, with dynamic and/or static splinting of the proximal interphalangeal joint. If improvement is not obtained with splinting, surgery can be proposed. Surgical treatment must correct the soft tissue contracture (flap and skin graft), the tendinous anatomical abnormalities and the joint contracture. Splinting and physiotherapy is necessary after surgery.
