Objective:To investigate the clinical effect of gracilis musculocutaneous flap in repair of perineal soft defect with open pelvic fracture.Methods:From June 2009 to June 2019, 11 cases of open pelvic fracture associated with perineal injury were treated in the Department of Trauma and Orthopaedic of 521 Hospital of Norinco Group. There were 4 males and 7 females aged 16-56 (33 in average) years old. Cause of injuries: 6 cases by traffic accident, 4 by falling from height, and 1 by crushing. All the patients had open pelvic fractures. According to Tile classification, 1 case was rated as type A, 7 as type B and 3 as type C. All the patients were accompanied with perineal injury and soft tissue defect. The wound sizes ranged from 5 cm×5 cm to 8 cm×12 cm. The defects were repaired with gracilis musculocutaneous flap. The size of gracilis myocutaneous flaps was 6 cm×5 cm to 9 cm×13 cm. All donor areas of the flap were sutured directly. After surgery, 11 patients treated with strengthened nutritional support, keep supine position to avoid abduction, and appropriately raise the lower limbs. Follow-ups were conducted regularly after surgery.Results:All patients entered 6 to 30 (22 in average) months of follow-up. All of 11 myocutaneous flaps survived, besides 1 had a few necrosis at the distal surface of the myocutaneous flap, and healed after change of dressing. All the incisions at donor site had stage I healing. The colour, texture and flexibility of the gracilis myocutaneous flap were good. There was a scar at the donor sites without causing obvious dysfunction. Over the follow-up period, there was no failure of flap in either the recipient and donor sites. The patients were satisfied with the appearance and function.Conclusion:Gracilis musculocutaneous flap is one of the ideal methods in repair of perineal soft tissue defect with open pelvic fracture.
