Foot salvage using microsurgical free muscle flaps in severely crushed foot with soft tissue defects.

OBJECTIVE

Management of complex foot injuries including skin, tendons, vessels, bone, with soft tissue defects is considered as an orthopedic challenge. Microsurgical free muscle flaps provide the best solution in such cases.

PATIENTS AND METHODS

Thirty two consecutive cases of complex ankle and foot injuries were treated by skin grafted muscle free flap in one stage procedure after radical debridement. Twenty four were males and 8 were females. Right foot was affected in 26 and left was involved in 6 patients. The average age was 22 years (range 6-33 years). The most common cause of injury was motor car accident. All cases had complex soft tissue defect with bone exposure. All cases were candidate for amputation. Gracilis muscle transfer was done in 26 cases and latissimus dorsi free flap in 6 cases. The average follow up was 38 months.

RESULTS

All the free muscle flaps survived. The involved bone fracture was united at an average 3 months. No evidence of osteomyelitis was noted. Full weight bearing was restored 3 months post-operatively. All patients were satisfied with the cosmetic appearance and functional capacity of their operated limbs.

CONCLUSION

Skin-grafted free muscle flap as one-stage procedure is a good solution for reconstruction of complex ankle and foot injuries.
