Objective To investigate the effectiveness of repairing severe cicatricial contracture deformity in the web-space by kite-like incision combined with full-thickness skin grafting. Methods Between June 2008 and September 2011, 31 patients (87 web-spaces) with severe cicatricial contracture deformities in the web-spaces were treated. There were 24 males and 7 females, aged 5-43 years (median, 22 years). The causes of injuries were flame burn (26 cases), scald (3 cases), electric arc burn (1 case), and chemical burn (1 case). The degree of burn was deep second degree (14 cases) and third degree (17 cases). The interval time from injury to operation was 10 months to 17 years (median, 2.2 years). The kite-like incision was marked on the scar in the web-space. The rhombic scar between the adjacent metacarpophalangeal joints was excised, and cicatricial contracture was released completely. The secondary wound in the web-space was repaired with full-thickness autogeneic skin grafting. The secondary wound at donor site was directly sutured. Results All full-thickness skin grafts survived well. The incisions at donor sites healed primarily. Of 31 patients, 29 (82 web-spaces) were followed up 6-18 months (mean, 13 months). The sizes and depths of reconstructed web-spaces were similar to those of normal ones. No secondary cicatricial contracture was observed, and the function of fingers recovered well. Conclusion The short-term effectiveness is satisfactory by kite-like incision combined with full-thickness skin grafting for repairing severe cicatricial contracture deformities in the web-space, while the long-term effectiveness needs further observation.
Objective To investigate the feasibility of repairing secondary wounds after scar excision in patients with scar contracture in whole dorsum of the hands by expanded full-thickness skin grafts. Methods Between February 2008 and February 2011, 15 patients (19 hands) with scar contracture in whole dorsum of the hands were treated. There were 12 males (14 hands) and 3 females (5 hands), aged 18-43 years (mean, 28.6 years). The disease duration was 6-22 months (mean, 13.2 months). All cases complicated by different degrees of metacarpophalangeal joint extension deformity and interphalangeal joint flexion deformity. In one-stage operation, soft tissue expanders were implanted at donor sites, and the time of water injection was 4-5 months; in two-stage operation, scar was excised and secondary wound (14 cm × 9 cm-25 cm × 16 cm in size) was repaired with the expanded full-thickness skin grafts. Results After one-stage operation, the others had good blood supply except 1 case of skin necrosis in the center of expanded skin flap. After two-stage operation, the full-thickness skin grafts survived well in 18 hands; subepidermal effusion occurred in 1 hand, which was cured after changing dressing. The incisions at donor sites healed well in all cases. All patients were followed up 6-18 months (mean, 13.7 months). The grafts were excellent in color, texture, and elasticity, and no hypertrophic scar was observed at the edge and joint of the grafts. The hand function recovered well; the flexion and extension of wrist joint, metacarpophalangeal joint and interphalangeal joint were normal. Conclusion The expanded full-thickness skin graft is a suitable solution to repair effectively scar contracture in whole dorsum of the hands because it has good results in the cosmetic appearance and function recovery of the hands.
