Free vascularized joint transfer: Case report

Abstract

The proximal interphalangeal joint provides the greatest contribution to the total arc of digital movement, therefore, the loss of normal movement of the joint has a considerable impact on function and grip strength. The only method that ensures the long-term preservation of the cartilaginous architecture, as well as a rapid recovery of traumatic or pathological joint destruction, is vascularized joint transfer. It is defined as a partial or complete partial transplant with preservation or immediate restoration of blood flow. We present the case of a 20-year-old man, with a history of contusive-cutting trauma on the ulnar border of the third finger of the left hand, area II, who underwent primary closure. Seven months after the presentation of the joint and functional disability for proximal interphalangeal joint flexion. A joint reconstruction process was performed, by means of a vascularized joint transfer of the 2nd toe of the right foot. Subsequently, follow-up was carried out through the outpatient clinic at 2, 4, 6 and 8 weeks, 6 months and 12 months. At 6 months he was subjected capsulotomy, volar plate release, osteosynthesis plates removal and cutaneous island thinning. Ranges of passive movement of extension of 85º and active of 70º were reached. Based on the experience of our center, it is shown that the use of the transfer was made in 2 stages of reconstruction, the range of both active and passive movements can be maintained for an adequate function.
