The medial adipofascial flap for infected tibia fractures reconstruction: 10 years of experience with 59 cases.

OBJECTIVE

The purpose of this study was to evaluate the results of the medial adipofascial flap (MAF) in infected tibia fractures reconstruction and to identify criteria for success or failure.

PATIENTS AND

METHODS

Fifty-nine patients treated with a MAF were enrolled. Age, BMI, tobacco use and bone status were recorded. Early and late postoperative complications were assessed. Bone healing and flap success were systematically evaluated at 12 months.

RESULTS

Tibia fractures were initially open in 48 cases (81%) and closed in 11 cases (19%). Infection was acute (<30 days) in 9 cases (15%) and chronic in 50 (85%). Thirty-one patients (53%) experienced no early postoperative complications (<30 days). There were 10 (17%) cases of necrosis of the skin graft, 2 (3%) cases of necrosis and 4 (7%) haematomas in the harvesting area, 7 (12%) cases of partial flap necrosis at its tip and 4 (7%) flap failures. None of the criteria was statistically correlated with the occurrence of a complication. At 12 months, 53 flaps (90%) were successful. Immediate skin graft were significantly correlated with flap success (P=0.05). Forty-six patients (78%) had complete bone healing documented by CT scan.

CONCLUSION

The MAF provides a reliable alternative for lower leg reconstruction. Its major advantages are sparing of the major leg vessels, no donor site morbidity and relatively easy and rapid dissection.
