Abstract:
Objective:To explore the clinical effects of perforator flaps in the reconstruction of hypertrophic scar contracture deformities in the large joints of extremities after severe burns.
Methods:From January 2008 to January 2018, 72 patients (53 males and 19 females, aged 5 to 63 years) with hypertrophic scar contracture deformities and functional disorder in the large joints of extremities after severe burns were admitted to the Department of Burns of Beijing Jishuitan Hospital. Scar hyperplasia and contracture deformity were located at shoulder joints of 28 patients, elbow joints of 15 patients, hip joints of 7 patients, knee joints of 17 patients, and ankle joints of 5 patients. The wound area of patients after the scars were excised and released ranged from 7 cm×6 cm to 34 cm×12 cm. The wounds were repaired with corresponding unexpanded perforator flaps or expanded perforator flaps according to the joint location and existing soft tissue conditions. The size of flaps ranged from 7 cm×6 cm to 35 cm×14 cm. The donor sites of 51 patients were sutured directly; the donor sites of 21 patients were repaired by segmented grafts or mesh grafts. The adopted surgeries, the survival of flaps after surgery, and the functional recovery of the joints during follow-up were recorded.
Results:Among the 72 patients, 53 patients had perforator flap repairing surgery only; 19 patients had perforator flap repairing surgery and skin grafting. Among them, 12 patients had expanded perforator flaps, 60 patients had unexpanded perforator flaps. The perforator flaps were performed free transplantation in 9 patients, pedicled transplantation in 61 patients, and groin transplantation in 2 patients. At last, 67 flaps survived completely, while 5 flaps had distal-end necrosis which were healed after dressing change or skin grafting after debridement. During follow-up of 6 months to 3 years, the joint function of all the patients was obviously improved. The abduction angles of shoulder joints were over 110°; the hip, knee, and elbow joints could reach the straight position, and the flexion was normal; the foot drop deformity was corrected, and the appearance of flaps was good with obvious extension compared with the original state.
Conclusions:Perforator flaps are suitable for reconstruction of hypertrophic scar contracture deformities in the large joints of extremities of patients after severe burns. They can restore the joint function to the greatest extent as well as repair the wounds.
