Recently, many studies have shown no difference in efficacy between musculocutaneous and fasciocutaneous flaps in the treatment of osteomyelitis [1]. The aim of this study was to examine the efficacy of the reverse sural fasciocutaneous flap for the reconstruction of chronic osteomyelitis defects on the distal lower leg. Between March 2013 and March 2018, five adult patients aged 38 to 85 years who underwent reconstruction with a reverse sural fasciocutaneous flap were included in this study (Table 1). These patients were diagnosed with chronic osteomyelitis at the Department of Orthopedic Surgery of Myongji Hospital and were referred to the Department of Plastic and Reconstructive Surgery for reconstruction of the soft tissue defects. Delayed distally-based fasciocutaneous reverse sural flaps were used in a 2-step procedure [2]. The patients were followed in our outpatient clinic and their healing status was quantitatively compared with previous findings by 3-phase bone scans, which all patients agreed to have performed for postoperative follow-up. Four of the five patients recovered progressively from osteomyelitis without complications, such as necrosis of the distal aspect of the flap or marginal dehiscence. These patients showed clinical resolution at the time of the last follow-up examination (Figs. 1-4). Complications such as necrosis and marginal dehiscence in the distal area often occur in reconstruction using a reverse sural flap. The authors performed a delayed procedure to overcome this and superficially undermined the proximal portion of the pedicle to protect the pedicle from twisting or kinking. However, in one case, chronic osteomyelitis had already progressed to bone necrosis and the patient underwent antibead insertion and a planned reoperation. The mean duration of follow-up for these patients was 9 months. During the follow-up of patients with 3-phase bone scans, the significant soft tissue uptake and increased blood flow due to the inflammatory reaction subsided gradually, and in cases with good results, these results disappeared completely. A reverse sural flap can be used to effectively treat chronic osteomyelitis without significant donor site morbidity or the complications that may occur during the elevation of a muscle flap [3]. This widely known flap is much simpler, requires less anesthetic time, and poses less risk to the patient than free tissue transfer, including muscles. Therefore, this flap may be a good option for the reconstruction of chronic osteomyelitis wounds on the lower leg.
