AbstractA systematic approach of the surgical management of a calcaneal fracture can minimize the potential of soft tissue complications. When reducing a closed calcaneal fracture, the incision used affects the postoperative complications. The L-shaped incision with the horizontal limb lying on the lateral glabrous junction ensures maximum blood flow to either side of the incision. Whether or not the wound can be closed primarily depends on the preexisting edema, the lost calcaneal height, and the delay between the fracture and reduction (Fig. 20). The wrinkle test is a good indicator that the incision can be closed primarily if the amount of height restored is minimal. If the edema is too great, steps should be taken to reduce it sufficiently to allow successful wound closure. If the wound, after reduction, is too wide to allow primary closure, an ADM flap laterally or an AHM flap medially should be used. For larger defects, a free flap should be considered. The three important steps to reconstruction of soft tissue defects around the calcaneus include good blood supply, a infection-free wound, and the simplest soft tissue reconstructive option that covers the wound successfully. Adequate blood supply can be determined by the use of Doppler. If the supply is inadequate, revascularization is necessary before proceeding. Achieving a clean wound requires aggressive debridement, intravenous antibiotics, and good wound care. Adjuncts that can help in achieving a clean wound include topical antibiotics (silver sulfadiazine), the VAC, and hyperbaric oxygen. Osteomyelitis has to be treated aggressively. Any suspicious bone has to be removed. Only clean, healthy, bleeding bone is left behind. Antibiotic beads can be useful when there is doubt as to whether the cancellous bone is infection-free. The beads are not a substitute for good debridement, however. Soft tissue reconstruction ranges from delayed primary closure to the use of microsurgical free flaps (Fig. 21). When bone or hardware is exposed, a muscle flap should cover the wound because of the extra blood supply it carries with it. The soft tissue option depends on the width of the wound. For wounds 1 cm wide or less, the options include allowing the wound to close by secondary intention (VAC), delayed primary closure, or a local muscle flap. For wounds 2 cm wide or less, allowing the wound to close by secondary intention (VAC) and a local muscle flap are the best options. For wider wounds, one has to assess whether the local muscle flap has sufficient bulk to close the defect. If it does, it is the simplest solution. If the local muscle is inadequate, a microsurgical free flap has to be used. The VAC sometimes can convert a large wound to a smaller wound so that a local muscle flap can be used. This procedure takes time, however, and adds to the cost of the repair.
