Objective To investigate the clinical significance of the distally-based sural musculocutaneous flap for the treatment of chronic calcaneal osteomyelitis. Methods From January 2002 to October 2005, 7 patients (4 males, 3 females; age range, 15-68 years ) were treated with the distallybased sural musculocutaneous flap, who had chronic calcanealosteomyelitis after calcaneal fracture. After the radical debridement for all the nonviable and poorly vascularized tissues, all the chronic calcaneal osteomyelitis patients, who had suffered from open calcaneal fracture or closed calcaneal fracture, were treated with the open reduction, the internal fixation, and thebone graft. The ulcer lasted for 3-12 months before diagnosis of osteomyelitis. The musculocutaneous flaps ranged in size from 8 cm×4 cm to 12 cm×7 cmand the muscle flaps ranged from 4 cm×3 cm to 6 cm×5 cm. The donor defects were closed primarily in 5 patients and were resurfaced with the splitthicknessskin graft in 2 patients. Results All the musculocutaneous flaps survived completely and all the wounds healed smoothly. All the patients followed up for 2-6 months had no recurrence of osteomyelitis or return to their preoperative ambulatory status.Conclusion It is feasible to use the distallybased sural musculocutaneous flap for treatment of chronic calcaneal osteomyelitis.
