Post operative surgical site infection following implant surgery is a major problem in orthopedic surgical practice. Infection occurring after internal fixation of a fracture is a devastating complication and may be difficult to treat. The frequency of occurrence of surgical site infection has decreased with improvements in aseptic technique. The objectives of the study are to determine the incidence of surgical site infection following orthopaedic related implant surgeries and to indentify the predisposing factors.
The study was a prospective study conducted at the National orthopedic hospital, Enugu. Wound surveillance was carried out for the 97 patients included in this study for a period of 6 months postoperatively. The diagnosis of surgical site infection was in accordance with the CDC's guideline for prevention of surgical site infection published in 1999.
The study included 61 males and 36 females giving a ratio of 1.7:1. The study population was aged 7 to 83 years with a mean age of 38.7 +/- 18.3 years. The infection rate was found to be 9.3% with staphylococcus aureus as the most common causative organism in 55.6% of cases. Two of the nine infected cases required implant removal. Significant factor was a theatre population of more than 6 persons.
Surgical site infection following implant surgery is relatively common in our environment with staphylococcus aureus as the major causative organism. Increased theatre populations increase the risk of implant associated surgical site infection.
植入物手术后的手术部位感染是骨科手术实践中的一个主要问题。骨折内固定术后发生的感染是一种毁灭性的并发症，可能难以治疗。随着无菌技术的改进，手术部位感染的发生率有所下降。本研究的目的是确定骨科相关植入物手术后手术部位感染的发生率，并确定易感因素。
本研究是在埃努古国家骨科医院进行的一项前瞻性研究。对本研究纳入的97例患者术后6个月进行伤口监测。手术部位感染的诊断符合1999年疾病控制与预防中心发布的手术部位感染预防指南。
该研究包括61名男性和36名女性，比例为1.7:1。研究人群年龄在7至83岁之间，平均年龄为38.7±18.3岁。感染率为9.3%，金黄色葡萄球菌是55.6%病例中最常见的致病菌。9例感染病例中有2例需要取出植入物。重要因素是手术室人数超过6人。
在我们的环境中，植入物手术后的手术部位感染相对常见，金黄色葡萄球菌是主要致病菌。手术室人数增加会增加植入物相关手术部位感染的风险。
