Effects of thickness of subcutaneous fat on the surgical site infection after lumbar posterior approach
Abstract：Objective To observe the effects of thickness of subcutaneous fat on the incidence rates of surgical site infection ( SSI ) after lumbar posterior approach.Methods The clinical data about 282 patients who underwent lumbar posterior approach in our hospital from May 2010 to May 2015 were retrospectively analyzed.The data of related risk factors including diabetes mellitus, body mass index ( BMI) , number of vertebrae involved in operation, as well as the horizontal distance from lamina of vertebra at L4 to skin surface and the thickness of subcutaneous fat at surgical site were collected, moreover,the correlation between these parameters and incidence rates of SSI was analyzed.Results Among 282 patients, 14 patients developed postoperative infections,with the incidece rate being 4.96%.The diabetes mellitus, obesity,number of vertebrae involved in operation were closely correlated to the incidence rates of SSI after operation ( P <0.05 or P <0.01) , moreover,the thickness of subcutaneous fat and the ratio of subcutaneous fat thickness/distance from lamina of vertebra to skin surface were also independent risk factors in occurrence of SSI after operation.Conclusion The thickness of subcutaneous fat at surgical site and the horizontal distance from lamina of vertebra to skin surface are independent risk factors in occurrence of SSI after operation,thus,these factors should be evaluated seriously before operation.
