[Repair of skin and soft tissue defects in shoulder and elbow with rotator scapular artery perforator flap, lateral thoracic perforator flap, or medial brachial artery perforator flap].

ABSTRACT

From January 2014 to June 2018, 12 patients with skin and soft tissue defects in shoulder and elbow were admitted to General Hospital of Ningxia Medical University with skin and soft tissue defect size of 6 cm×5 cm to 11 cm×8 cm, including 9 males and 3 females aged 15-56 years. Wounds of 5 patients were repaired with rotator scapular artery perforator flap (flap area of 8 cm×7 cm to 12 cm×6 cm), and the donor flap area was sutured directly. Wounds of 3 patients were repaired with lateral thoracic perforator flap (flap area of 8 cm×7 cm to 13 cm×9 cm). The donor flap area of two patients was sutured directly, the majority of the donor flap area of one patient was sutured directly, and a small part was covered by split-thickness skin graft from ipsilateral thigh. Wounds of 4 patients were repaired with medial brachial artery perforator flap (flap area of 6 cm×5 cm to 12 cm×10 cm). The donor flap area of two patients was sutured directly, and two patients were covered with split-thickness skin graft from left chest wall. The flaps of 11 patients survived after surgery. Blood flow disorder at the distal end of the flap was observed in one patient. After treatment, the distal end of the flap presented 3 cm×2 cm necrosis, and the skin graft survived after second skin grafting and debridement. During the follow-up of 6 to 24 months post surgery, all patients had good texture of flap, with light scar hyperplasia in the donor flap area, and good recovery of elbow and shoulder joint function. The rotator scapular artery perforator flap, lateral thoracic perforator flap, and medial brachial artery perforator flap with the advantages being of relatively simple operation, high survival rate, and good surgical outcome, are good choices for repairing the skin and soft tissue defects in shoulder and elbow.
