Background: Controversy still exists regarding the optimal method for post-operative skin closure in orthopedic surgery. In total knee replacement, closure with metal staples is faster but carries a higher surgical site infection (SSI) risk. Other studies have found differing results in foot and ankle and hip surgery. Very little evidence exists on this subject after spine surgery. The aim of this study was to determine whether closure of the skin incision in open posterior spine surgery carries a different rate of post-operative SSI when using nylon sutures compared with metal staples.

在后路开放性脊柱手术中，尼龙皮肤缝合线术后感染的危险性比金属钉更低：一项回顾性病例对照研究，涉及270例患者。

背景：关于骨科手术中术后皮肤闭合的最佳方法仍存在争议。在全膝关节置换术中，用金属钉闭合的速度更快，但手术部位感染（SSI）的风险更高。其他研究发现在脚踝和髋关节手术中的结果不同。在脊柱手术后，关于这个问题的证据很少。这项研究的目的是确定与金属钉书钉相比，当使用尼龙缝线时，在开放式后路脊柱手术中闭合皮肤切口是否具有不同的术后SSI率。
