Abstract:
Objective:To investigate the clinical efficiency of gastrocnemius muscle flap combined with antibiotics loaded calcium sulfate in the treatment of postoperative infection and plate exposure of tibial plateau fracture in elderly patients.Methods:From January, 2015 to May, 2019, 21 elderly patients with postoperative infection and plate exposure of tibial plateau fracture were treated, including 14 males and 7 females with an average age of 72.6 years, ranging from 61 to 82 years. The average course of disease was 22.7 days, ranging from 6 to 91 days. The site of wound infection was at medial in 8 cases, lateral in 9 cases and bilateral in 4 cases. The size of wound ranged from 2.0 cm×3.5 cm to 5.0 cm×12.0 cm. All wounds were implanted with antibiotics loaded calcium sulfate and repaired by gastrocnemius muscle flap combined with skin graft after debridement. Muscle flap survival, wound healing, inflammatory index, fracture healing and knee joint function were recorded. The curative effect was evaluated by McKee infection treatment criteria and the knee joint function was evaluated by HSS scoring criteria.Results:All 21 muscle flaps survived. In 1 case, skin graft necrosis occurred in a small area, and the wound healed well after dressing change. One case had exudation which was clear and the bacterial culturing was negative, and the wound healed after 2 weeks of dressing change. The other incisions were healed in stage I, and the healing rate was 90%. All patients were followed-up for an average of 28.7(16-39) months. The redness and swelling occurred in 1 case without exudation after 2 months which disappeared after anti-infection treatment and didn't recur again. The infection recurred in 1 case after 5 months, and it which was controlled after debridement and plate removal. According to McKee criteria, 19 cases were cured, 1 improved and 1 recurred with an effective rate of 95.2%. The fracture healing time was from 3 to 7 months, with an average of 4.6 months. According to HSS scoring criteria, the knee joint function was excellent in 12 cases, good in 7 cases and moderate in 2 cases.Conclusion:After thorough debridement, gastrocnemius muscle flap combined with antibiotic loaded calcium sulfate can effectively control the infection, repair the wound, promote fracture union and restore limb function in the treatment of postoperative infection and plate exposure of tibial plateau fracture in elderly patients.
