Efficacy of Treating Chronic Tibial Osteomyelitis With Bone Defect Using a Pedicled Perforator-Layered Flap and Fasciocutaneous Flap of the Posterior Tibial Artery: A Case Report.

Introduction Tibial osteomyelitis is a common complication of bone tissue trauma. Obtaining good soft tissue coverage and effective infection management is key to the treatment of chronic osteomyelitis of the tibia accompanied with bone defect and bone exposure. The pedicled posterior tibial artery perforator layered fasciocutaneous flap can be used to repair soft tissue defects and can be used as a long-term, localized anti-infective. Case report A 54-year-old male presented with an ulcer, purulent discharge at the left anterior tibia, and a fever 28 years after complete healing of the scar site. The patient received debridement and negative pressure wound therapy (NPWT) in a hospital setting. After presenting to the authors' department, there was difficulty in closing the exposed bone marrow cavity. On the basis of systemic use of intravenous antibiotics, multiple debridements and NPWT were used to effectively remove necrotic tissue and control infection. Afterward, the pedicled posterior tibial artery perforator layered fasciocutaneous flap was designed to fill the bone marrow cavity as well as cover and seal the wound of bone exposure and soft tissue defect simultaneously. The layered fasciocutaneous flap was well established after operation, and no recurrence of osteomyelitis was found. Conclusion Debridement with negative pressure wound therapy can be an effective treatment for the wound bed preparation in advance of surgery, and the pedicled posterior tibial artery perforator layered fasciocutaneous flap can be used for the treatment of several soft tissue defects.
