BACKGROUND: Utilization of combined local muscle flaps for Gustilo type IIIB open tibial fractures has not been clearly delineated. We describe a combination of medial gastrocnemius and hemisoleus flaps for managing open tibial fractures accompanying large or double soft tissue defects. METHODS: Twelve patients with Gustilo IIIB open fractures of the tibial shaft with large (9) or double (3) defects were operated on by fracture stabilization and combined medial gastrocnemius and hemisoleus flap coverage. Data were collected on types of implants, types of flaps, union time, postoperative complications, and Puno functional scores. RESULTS: Regarding implants for fixation, an intramedullary nail was used in three patients, plate and screws in five, combined plate and intramedullary nail in one, and definitive external fixation was used in three. Regarding soft tissue coverage, combined medial gastrocnemius and hemisoleus flaps were used in ten patients, combined hemigastrocnemius and hemisoleus in one, and combined medial gastrocnemius and reversed hemisoleus in one. All flaps survived, and all fractures were united with a mean union time of 19.7 weeks (range 16-24). Tip necrosis of the hemisoleus flap occurred in two patients. Regarding Puno functional score, one was determined to be excellent, nine was good and two was fair. CONCLUSION: Combined medial gastrocnemius and hemisoleus flaps are reliable and effective for open tibial fractures complicated with large or double soft tissue defects.
