Retrospective study on the influence of smoking,overweight and alcoholism on femoral head necrosis after internal fixation of femoral neck fracture
Objective Investigating the relationship between smoking,overweight,and bibulosity with plasma PAI-1 and osteonecrosis of the femoral head after internal fixation by retrospective study,and providing reference for clinical treatment.Methods A total of 95 patients with femoral neck fracture treated with internal fixation from January 2021 to January 2022 were retrospectively studied.The data of smoking,overweight,alcohol abuse,preoperative and postoperative plasma PAI-1 levels were collected.The patients were divided into necrosis group and non-necrosis group according to the occurrence of femoral head necrosis at the last follow-up.Univariate analysis was performed on smoking,overweight,alcohol abuse,plasma PAI-1 level before and 2 days after operation,and the presence of smoking,overweight and bibulosity factors was analyzed.The association of smoking,overweight and bibulosity with plasma PAI-1 level was analyzed.Figure out the relationship between smoking,overweight,bibulosity and plasma PAI-1 and femoral head necrosis after internal fixation.Results Femoral head necrosis occurred in 22 of 95 patients.Age,gender,smoking,overweight and bibulosity were not independent risk factors for postoperative femoral head necrosis(P＞0.05).The plasma PAI-1 level at 2 days after operation in necrosis group was(46.95±2.35)ng/ml,which was significantly higher than that in non-necrosis group[(41.94±4.73)ng/ml,P＜0.05].The level of plasma PAI-1 at 2 days after operation was(48.29± 1.78)ng/ml in patients with smoking,overweight and alcohol abuse at the same time,which was significantly higher than that in other patients[(42.40±4.60 ng/ml,P＜0.05].In addition,when the smoking,overweight,and bibulosity were concurrent,it was a risk factor for femoral head necrosis(P＜0.05).Conclusion When the smoking,overweight,and bibulosity were concurrent,it can increases the risk of osteonecrosis of the femoral head after internal fixation,which may be related to the significant increase of plasma PAI-1 level,especially at 2 days after surgery.
