Sacral blistering

A 44-year-old man with T-4 paraplegia presented to the Family Medicine Clinic with concern for blisters and shearing of the skin on his buttocks. Since undergoing rotator cuff surgery 6 weeks earlier, it had become difficult for him to transfer on and off his non-custom wheelchair.

What’s your diagnosis?

This patient had sustained multiple pressure injuries. The superior aspect of this image shows bullous change with intact dermis, which would classify that area of injury as a Stage 2 pressure injury.1 An older injury in the coccygeal area was through the dermis (Stage 3), with some eschar seen at the base, making that area unstageable.1 (There may have been deeper injury under the eschar.)

This patient was at heightened risk for pressure injury because of his paraplegia.2 Fortunately, he had some preserved sensation. However, his rotator cuff surgery made it harder for him to smoothly transfer to and from the wheelchair, leading to sheer forces against his skin. Social determinates of health care pose an additional risk for pressure injuries. Without a properly fitted wheelchair and cushion, there is an increased risk of localized pressure over both bony prominences and parts of the body that come into contact with mechanical elements of the wheelchair.

Treatment for all pressure injuries includes relief of pressure on the affected area. In this patient’s case, he had to stay in bed (and out of the wheelchair) so that he could heal.

This patient was very knowledgeable about his condition and pressure injuries. He had already arranged for a wheelchair fitting and a visit with the wound care team. His Stage 2 injury had a bullous change instead of absent epithelium, so rather than an adherent hydrocolloid dressing (which would likely remove the loosened epithelium), he was provided with a nonadherent dressing to the area, then an absorbent foam overdressing.

An image of the patient’s deeper sacral injury was shared with the wound care team, which recommended filling the area with a silver rope dressing for its absorptive filler and antibacterial properties. The area was then covered with an absorbent foam. The patient planned to follow up with the Wound Care Clinic for reevaluation and ongoing treatment.
