[Results of the reconstruction of the middle phalangeal base of the finger through an osteochondral autograft from the hamate bone]. Handchir Mikrochir Plast Chir. 2018 Feb;50(1):36-43 Authors: Pillukat T, Kalb K, Windolf J, van Schoonhoven J Abstract OBJECTIVE: The fractured base of the middle phalanx was reconstructed in 13 patients using an osteochondral transplant from the carpometacarpal joint surface of the hamate bone. The goal was to restore joint stability with preservation of mobility. Indications were acute and missed isolated destruction of the palmar middle phalanx base ≥ 30 %. Contraindications were destruction of the head of the proximal phalanx, advanced chondropathy of the head of the proximal phalanx, and extensive soft tissue injury with loss of skin coverage for the proximal interphalangeal joint. SURGICAL TECHNIQUE: In this procedure the fractured middle phalangeal base was debrided and the defect replaced by a size-matched autograft from the dorsal carpometacarpal osteoarticular surface of the hamate bone, which was secured in place with miniscrews. RESULTS: Bone fusion was achieved in 100 % with restoration of joint congruity in 12 of 13 cases and a slight subluxation in one case. Follow-up was possible in 9 cases after 23 (5-51) months. The average range of motion in the reconstructed joint for extension/flexion was 0/9/73°; grip strength was 82 % of the unaffected side. Five out of 9 patien...
