Objectives To investigate the curative effect of skin flap and allogenic tendon in reconstructing l imbs function of complex soft-tissue defect. Methods From May 2001 to December 2007, 43 cases of complex soft-tissue defect of l imbs were repaired by pedicled skin flaps, free skin flaps, cutaneous nerve nutrient vessel skin flaps and arterial island skin flaps for primary stage, then the function of the l imbs were reconstructed with allogeneic tendon after 2-3 months of skin flap
operation. There were 31 males and 12 females, aged 5-53 years(mean 25 years). Injury was caused by machine in 28 cases, by traffic accident in 14 cases and others in 1 case. There were 27 cases in upper l imb, 16 cases in lower l imb. Twenty-six cases compl icated by bone fracture, dislocation and bone defect, the most of bone defect were cortical bone defect. The sizes of skin and parenchyma defect were 9 cm × 4 cm to 37 cm × 11 cm, the length of tendon defect was 6 to 26 cm. The sizes of skin flaps were 10 cm × 5 cm to 39 cm × 12 cm. Allogeneic tendons were used 2-6 strips(mean 4 strips). Results Forty-three cases were followed up for 5-56 months (16 months on average), all flaps survived. The donor area healed by first intention, the incision healed by first intention in second operation, and no tendon rejection occurred. The cl inical heal ing time of fracture was 3-8 months, and the cl inical heal ing time of allograft was 6-8 months. Six cases were given tenolysis for adhesion of tendon after 3-5 months of tendon transplantation. The postoperative flexion of wrist joint was 20-50°, the extension was 20-45°. Articulatio metacarpophalangea and articulatio interphalangeae could extend completely. The flexion of articulatio metacarpophalangea of thumb was 20-45°, the flexion of articulatio interphalangeae was 30-70°. The flexion of articulatio metacarpophalangea and articulatio interphalangeae of the other fingers was 60-90°. The postoperative ankle can extend to neutral position, the neutral position of ankle was 30-50°. The flexion of articulatio metatarsophalangeae and articulatio interdigital was 20-40°. The
extension of articulatio metatarsophalangeae was 30-60°. Conclusion Through designing systematically treatment plan,
practicing operation by stages, preventing adhesion of tendon actively and exercising function reasonably, the functions of l imbs reconstructed by allogenic tendon and skin flap can leads to satisfactory effect.
