“…Although nonvascular bone grafting is a common technique for the reconstruction of defects smaller than 4–6 cm that would allow healing [ 7 , 16 ], the IMT provides an attractive microenvironment with unrivaled bioactivity of various and adequate proteins for protecting and promoting osteogenesis of the IM; therefore, the IMT provides much better conditions for achieving bone union than traditional iliac crest bone grafting [ 17 ]. All patients in the series achieved bone union after a mean of 8.6 weeks, including patients with emergency traumatic bone defects and posttraumatic osteomyelitis.…”

Purpose The purpose of this study was to explore the feasibility and evaluate the clinical outcomes of treatment for phalangeal and metacarpal segmental defects with the induced membrane technique and autologous structural bone grafting. Methods Sixteen patients who sustained phalangeal or metacarpal bone segmental defects were treated by the induced membrane technique and autologous structural bone grafting from June 2020 to June 2021 at our center. Results The average follow-up was 24 weeks (range, 12–40 weeks). Radiography demonstrated union of all bone grafts after an average of 8.6 weeks (range, 8–12 weeks). All incisions at donor and recipient sites demonstrated primary heal without infection complications. The mean visual analog scale score of the donor site was 1.8 (range, 0–5), with a good score in 13 cases and a fair score in 3. The mean total active motion of the fingers was 179.9°. Conclusions The feasibility of the induced membrane technique and structural treatment with a cylindrical bone graft for segmental bone defects of the metacarpal or phalanx is demonstrated by follow-up radiography results. The bone graft provided much more stability and structural support in the bone defects, and the bone healing time and bone union rate were ideal.

Vascularized bone grafts of the wrist and hand help to achieve bone union in various clinical settings such as bone fusion or nonunion treatment. Among the multiple possible donor sites, the base of the second metacarpal is convenient because of its relatively straightforward harvesting, lack of impairment of the hand vascularization, sufficient bone supply for small joint fusion and phalanx or metacarpal nonunion management. The flap is versatile as it can reach any carpal and metacarpal bone as well as the proximal phalanx of all fingers. The arc of rotation of the flap depends on which side of the dorsal intercarpal arch it is based, either radially or ulnarly. It can also be pedicled distally by a retrograde flow through the second dorsal metacarpal artery. The robust vascularization of the flap allows for reliable healing. We present five new indications in various clinical settings that illustrate the versatility of the arc of rotation of the flap.
