Abstract
Reconstruction of the exposed lower third tibia and ankle region remains a difficult task and a challenge for reconstructive surgeons. Microsurgical flaps have been the method of choice for this reconstruction, but in our hospital, we do not have equipment or a microsurgical-trained team for this type of procedure. Moreover, free muscle flaps have more risk of failure and sometimes the patient's clinical condition does not allow a more complex surgery in some cases. Local muscle flaps are preferred in these situations. METHODOLOGY: This study was carried out in the Burn and Plastic Surgery Department, Rajshahi Medical College Hospital, Rajshahi from July 2015 to December 2021 on 100 patients ( 89 males and 11 females with ages ranging between 21 and 62 years). Patients with tibial defects in the distal third of the tibia which need soft tissue coverage were selected. RESULTS: Our study shows that reversed medial hemisoleus muscle flap had an excellent outcome with short surgical duration, easy implementation, excellent resolution, and low morbidity of the donor area. Moreover, preservation of the lateral portion is suitable for plantar flexion showing a long arc of rotation. CONCLUSION: Medial hemisoleus muscle flap is a reliable option for the reconstruction of soft tissue defects with the exposed bone of the distal leg based on perforators of the posterior tibial artery. Careful flap dissection with preservation of as many perforators as possible is the key to success.
