Pressure ulcers remain a common health problem, particularly among physically limited or bedridden older adults, and they can cause significant morbidity and mortality. Conservative management is ineffective for stage III or IV pressure ulcers, and surgery to create flap coverage becomes inevitable. Basic surgical principles for the treatment of pressure ulcers include complete excision of the ulcer, surrounding scar, underlying bursa, and soft tissue calcification; radical removal of underlying bone and any heterotropic ossification; padding of bone stumps and filling dead space; resurfacing with large regional pedicled flaps; and grafting the donor site of the flap, if necessary. For effective edge resection, all the flaps should be designed to be as large as possible, placing the suture line away from the area of direct pressure, and the flap design should also not violate adjacent flap territories to preserve all options for coverage if a breakdown or recurrence dictates further reconstruction. There are surgical methods for stage III or IV wide range pressure ulcers: reconstruction surgery using a skin flap, muscle flap, fascia-skin flap, or free flap. The skin graft is not generally recommended as a surgical procedure for stage III or IV pressure ulcers because it cannot provide enough strength to cover the wound. This review presents various surgical treatments of pressure ulcers including muscle, musculocutaneous, perforator-based, and free flap.
