Immediate recognition of anastomotic failure is important to ensure the viability of the vascularised fibular graft. The problems associated with post-operative bone scanning and angiography for immediate detection of anastomotic failure have been described.
Mandibular resection, following surgery for tumor or osteoradionecrosis, leaves a patient with a swallowing, speech, and cosmetic disability. Repair of the oromandibular defect is difficult and various prostheses and grafts have been used and reported. The most popular form of mandibular reconstruction is the use of the free, vascularized bone transfer. We report our experience with the free vascularized fibula bone transfer in eight patients.
Thirteen patients had skeletal reconstruction using vascularised fibula graft following resection of the diseased bone. Eleven patients had reconstruction of the lower limbs and two patients of the upper limbs. Clinical and radiographical evidence union were achieved with the average time of 32 weeks (earliest eight weeks). Six out of 11 patients (54%) in lower limb reconstruction started weight bearing at the average of 27 weeks. Bony union in this study is comparable with other studies using vascularised fibula graft.
Long bone reconstruction using vascularized fibula graft is becoming more popular despite the difficulties and its post-operative complications. We reviewed our early experience dealing with vascularized fibula graft for the management of massive long bone defect. Thirteen patients had undergone long bone reconstruction using vascularized fibula graft. Early complications that had been encountered include superficial wound infection (23%), transient common peroneal nerve palsy (23%), stage 1 bed sore (7.7%), anastomotic venous thrombosis (30.8%), DIVC (15.4%), flap loss and amputation (7.7%), and reactive psychiatric problem (7.7%). The early complications following this procedure are comparable with other major orthopaedic surgery and most of them are minor and treatable. The complication rates are also comparable with similar surgery done elsewhere.
Management of severe open tibial fracture with neurovascular injury is difficult and controversial. Primary amputation is an acceptable option as salvaging the injured, insensate, and ischaemic limb may result in chronic osteomyelitis and non-functional limb. We report a case of open tibial fracture associated with segmental bone and soft tissue loss, posterior tibial nerve and artery injuries, which was further complicated by chronic osteo-myelitis treated with composite vascularised osteocutaneous fibula and sural nerve graft. Functional outcome of the injured limb at one-year follow-up was satisfactory: the patient was capable of achieving full weightbearing and was able to appreciate crude touch, pain, proprioception, and temperature at the plantar aspect of the foot. There was no pressure sore or ulceration.
