Preliminary application of foldable pedicled latissimus dorsi myocutaneous flap for repairing soft tissue defects in shoulder and back / 中国修复重建外科杂志

OBJECTIVE@#To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back.@*METHODS@#Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage.@*RESULTS@#All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site.@*CONCLUSION@#The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

Application of plantar medial thin skin flaps preserving plantar fascia with its superficial fascia tissue to repair skin defects in hands and feet / 中国修复重建外科杂志

OBJECTIVE@#To explore the feasibility and effectiveness of plantar medial thin skin flaps preserving plantar fascia with its superficial fascia tissue to repair skin defects in hands and feet.@*METHODS@#Between July 2017 and January 2023, 35 cases of hand and foot defects were repaired with plantar medial thin skin flaps preserving plantar fascia with its superficial fascia tissue (13 pedicled flaps and 22 free flaps). There were 18 males and 17 females, with an average age of 38.8 years (range, 8-56 years). Thirty cases of defects were caused by trauma, and the interval between injury and admission ranged from 2 to 6 hours (mean, 3.3 hours). Three cases were ulcer wounds with a course of 3.0, 3.8, and 7.0 months, respectively. Two cases were malignant melanoma. Eight cases of wounds located in the fingers, 13 cases in the palm, 12 cases in the heel, and 2 cases in the distal foot. The size of skin defects ranged from 4.0 cm×3.5 cm to 12.0 cm×10.0 cm, and the size of flap ranged from 5.0 cm×4.5 cm to 13.0 cm×11.0 cm. The donor sites were repaired with skin grafts.@*RESULTS@#All flaps were survived and the wounds healed by first intention after operation. The partial necrosis at the edge of the skin graft occurred in 1 case, which healed after dressing change; the other skin grafts survived successfully. All patients were followed up 6-24 months (mean, 18 months). The flaps exhibited similar color and thickness to the surrounding hand and foot skin. Two-point discrimination ranged from 7 to 10 mm in the flaps with an average of 8 mm. The donor sites had no painful scars or sensory abnormalities. Foot and ankle functions were good and gaits were normal.@*CONCLUSION@#Application of plantar medial thin skin flaps preserving plantar fascia with its superficial fascia tissue to repair skin defects in hands and feet had good flap shape, high survival rate of skin graft at the donor site, and no obvious complications.
