Pressure ulcer coverage with contralateral gracilis Unfortunately, despite adequate flap coverage, nearly one-third of patients will develop a recurrent pressure ulcer[4,5]. A history of previous pressure ulcer increases the risk of developing a second pressure ulcer, particularly in the ischial region[1,6]. Fortunately, many of the flaps commonly used for pressure ulcer treatment can be readvanced or reused under certain conditions. However, difficulty arises when the patient requires repeated coverage of large ulcers in the same location and has exhausted the available local muscle options. Here, we present a case of recurrent ischioperineal ulcer in which the contralateral gracilis muscle was used for wound coverage. CASE REPORT Our patient is a 49-year-old Hispanic male with T3 incomplete paraplegia due to a motorcycle accident in Figure 1: A view of the right ischioperineal ulcer with the patient 1984. His comorbidities include neurogenic bowel and in the prone position. Note the multiple previous incisions. The planned left gracilis muscle flap and right V-Y hamstring bladder, lower extremity spasms, gallstones, chronic myocutaneous advancement flap were marked preoperatively anemia, and depression. Past surgical history includes exploratory laparotomy, orchiopexy, colostomy, and left hip incision and drainage with partial osteotomy and antibiotic cement spacer. He has had multiple pressure ulcers, requiring flap surgery, in the past, including: (1) bilateral gluteus maximus sliding island advancement flaps for a stage IV sacral ulcer in 2010; (2) a right gracilis myocutaneous flap for a stage IV right ischial ulcer in 2014; (3) a right biceps femoris muscle flap and tensor fascia lata rotation flap for a stage IV right posterior trochanter ulcer in 2016; and (4) a right Girdlestone procedure, femoral shortening osteotomy, right vastus lateralis muscle flap, and right posterior thigh fasciocutaneous rotation flap for stage Figure 2: Antro posterior (AP) radiograph of the patient’s pelvis IV right posterior trochanter and ischioperineal ulcers demonstrates rotation, bony resorption, and heterotopic ossification in 2017. of the pelvis. History of a right Girdlestone procedure and shortening of the right femur is evident. The left femoral head has been resected and antibiotic cement spacer was placed in the left Three months following the most recent right posterior acetabulum for treatment of a prior infection trochanteric and ischioperineal ulcer repair, the patient presented with sepsis due to a recurrent and extensive right ischioperineal stage IV pressure ulcer, which developed from an injury sustained while transferring from wheelchair to shower [Figure 1]. A plain radiograph of the patient’s pelvic anatomy is shown in Figure 2. Based on the location of the wound, there was concern for urethral involvement, however, urethrogram did not demonstrate a leak. Ulcer debridement and closure with the left gracilis muscle and a right V-Y hamstring advancement flap was planned. The patient was placed in the prone position and the right ischioperineal ulcer was excised down to healthy, bleeding tissue, taking care to protect the rectum and Figure 3: The right ischioperineal ulcer was debrided down to healthy bleeding tissue and the prominence of the ischial bone was urethra, both of which were in close proximity to the reduced.

The left gracilis muscle was harvested through a longitudinal left posteromedial thigh incision and tunneled subcutaneously across the perineum to cover the exposed right ischial bone [Figure 4]. A V-Y hamstring myocutaneous advancement flap was outlined, with sufficient width to cover the wound. The biceps femoris muscle, which had been advanced Figure 7: At 4 weeks postoperatively, all incisions are closed and previously to cover a prior ulcer, was re-elevated well-healed proximally and released distally to provide maximal advancement to fill the dead space in conjunction with the left gracilis muscle [Figure 5].
