Staged Operation Using Fasciocutaneous Transposition Flap on Reconstruction of Exposed Patella Region in 4th Degree Burn: Case Report

ABSTRACT

PURPOSE: Soft tissue injuries of the patellar region are difficult problems because of insufficient arterial blood supply and lack of muscle. There have been many methods for reconstructing the soft tissue injuries of the patellar area such as primary closure, skin graft, muscle flap and free tissue transfer. However, each method has some limitations in their application. We used fasciocutaneous transposition flap according to limitations of patient's condition. METHODS: A 67-year-old-man was hospitalized by contact burn with TBSA 15% involving scalp, back, buttock, both legs. We found 20x30 cm2 sized eschar on right knee. We debrided necrotizing patella bone and found insufficient blood supply. In addition, general weakness, low weight (170 cm/42 kg), old age, DM made us to plan 2 staged operation. At first, coverage using medial fascio-cutaneous transposition flap. After 7 days, there were 1/4 necrosis by congestion. we used Vancomycin for systemic antibiotic treatments and betadine irrigation. 2 weeks after, We debrided necrotizing patella bone and coverage using lateral fascio-cutaneous transposition flap. RESULTS: There were no post-operative complications such as infection, hematoma, seroma or flap necrosis. And there was no contracture or contour deformity. CONCLUSION: Due to limitations of patient's condition, we used fasciocutaneous transposition flap instead of musculocutaneous flap or free flap. We gained satisfactory result by using fasciocutaneous flap in patella exposed wound reconstruction.
