The use of fibular graft for the reconstruction of bone defects has been demonstrated to be a reliable method. The aim of this study was to assess the clinical outcome of graft union, functional outcome (hypertrophy of the graft bones) and complications of both non-vascularized and vascularized grafts.From 1981 to 2015, 10 patients were treated using non-vascularized fibular graft or free vascularized fibular graft. The outcomes were bony union time, graft hypertrophy and complications based on radiograph and functional outcomes according to the Musculoskeletal Tumor Society (MSTS) score. Mobility of the ankle at the donor site was evaluated using the Kofoed ankle score system.This study included 10 patients with an average follow-up of 6.8 years. The union rate for all patients was 100%. The mean union time was 21.3 weeks for vascularized fibular grafts and 30.5 weeks for non-vascularized fibular grafts (P = .310). There was a significant difference between the upper limbs and the lower limbs regarding hypertrophy of the grafts in 5 patients (P = .003). The mean MSTS score in 10 patients was 84% (range 53%–97%). Stress fracture of the graft occurred in 1 patient. Donor site complications, including valgus deformity and length discrepancy, between 2 legs occurred in 2 patients who were under 18 years of age at the time of operation (P = .114). The mean Kofoed score was 96.8 (range 88–100).A greater increase in hypertrophy of grafts was observed with reconstruction in the lower limbs. There was no difference in MSTS score between these 2 types of grafts. Children were more likely to experience the valgus deformity at the donor site after harvesting the fibula. Keeping at least the distal 1/4 of the fibula intact during the surgery is a valid means of ensuring ankle stability at the donor site, and children should be considered for prophylactic distal tibiofibular synostosis creation to prevent the valgus deformity of the ankle at the donor site.

This article reports 2 cross-leg free composite tissue flaps for repairing the severe composite tissue defects in lower leg without suitable adjacent recipient vasculature for microvascular anastomosis. The osseous myocutaneous flap of ilium and tensor fascia lata pedicled with ascending branch of lateral femoral circumflex vessels and the osseous muscle flap of scapula and latissimus dorsi pedicled with subscapular vessels were performed, respectively, to reconstruct the bone and soft-tissue defects in the lower leg of 2 patients. Both donor vessels were the posterior tibial artery and great saphenous vein from the contralateral lower leg. The legs and the bone flaps were immobilized by an external fixator. The periods of pedicle division were 43 and 67 days, respectively, after transplantation. Both flaps survived after pedicle division and the patients regained the ability to walk. There were no such complications as joint stiffness or donor site morbidity except for a linear scar. The 2 cross-leg free composite tissue flaps were optional methods for salvaging limbs that were otherwise nonreconstructable. But the indication for cross-leg free-tissue flap should be limited strictly.

The object of this study was to compare the outcomes of the vacuum assisted closure (VAC) therapy and conventional wound care with dressing change for treatment of complex wounds in patients with replantation of amputated upper and lower extremities. Data of 43 patients with replantation of amputated extremities from May 2004 to December 2011 were reviewed. There were 18 wounds of 18 patients with replantation, which were treated by dressing change and 26 wounds of 25 patients by VAC therapy. The outcomes were evaluated by the survival rate of replanted extremities, growth of granulation tissue, interval between wound treatment and secondary procedure and eventual secondary wound coverage methods. Vascular thromboses were found in 3 patients with wound treatment by dressing change and 5 by VAC. All replants of two groups of patients survived after salvage procedures. The wound score was 3.6 ± 0.7 in the conventional dressing change group and 5.8 ± 0.7 in the VAC group at the sixth day after treatment, respectively. The intervals between wound treatment and secondary wound coverage procedure were 12.0 ± 1.7 days in the dressing change group and 6.1 ± 0.7 days in the VAC group. Flaps were applied for wound coverage in 9 out of 18 (50.0%) wounds in the dressing change group and 5 out of 26 (19.2%) in the VAC group (P < 0.05), when the wounds of rest of patients were covered by the skin graft. The results showed that VAC could promote the growth of granulation tissue of wound, decrease the need of flap for wound coverage, and did not change the survival of replantation.
