The principles that guide treatment methods for bone and soft-tissue defects after emergency surgery for severe finger trauma remain a matter of debate. In particular, methods to treat severe damage of the middle part of a finger or reconstruction following failed replantation or degloving injury are challenging. Here, we retrospectively reviewed 5 cases of finger reconstruction using a vascularized corticoperiosteal flap from the medial femoral trochlea (VCMFT). For all cases, bone union and soft-tissue coverage was achieved within 3 months. The iliac bone, costal osteochondral graft and phalanx removed from the injured finger were used and wrapped by the VCMFT. The union between the bone matrix and the VCMFT was evaluated by serial X-rays or Computed tomography (CT), which allowed for visualization of bone matrix remodeling through the VCMFT. In one case, bone resorption at the fingertip was observed, requiring additional surgery. When preparing vascular anastomosis of the VCMFT at the recipient site in the injured finger, the distal end of the recipient digital artery may be used as a drainage vein. Thus, VCMFT is a useful treatment technique.
