Effect of obesity on the treatment of femoral neck fracture with SuperPATH hip arthroplasty / 中国基层医药

ABSTRACT

Objective To explore the effect of obesity on the treatment for femoral neck fracture in patients with SuperPATH hip replacement.Methods Seventy patients who were treated with SuperPATH hip replacement in the Second People's Hospital of Wuxi from January 2014 to January 2017 were selected in the study.Based on their body mass index(BMI),the patients were divided into obesity group(BMI ≥30kg/m2) (23 cases),overweight group (BMI25-30kg/m2) (22 cases),and normal group(BMI18.5-25kg/m2) (25 cases).The incision length,operation time,blood loss,blood transfusion rate,pain score,hip joint function score,imaging measurement results and postoperative complications were compared among the three groups.Results All 70 patients received the operation successfully.The incision length of the obesity group was (7.4 ± 0.2) cm,which of the overweight group was (7.2 ±0.1) cm,which of the normal group was (7.1 ± 0.8) cm,the difference among the three groups was statistically significant (F =24.671,P ＜ 0.001).The patients were followed up for 9-13 months.The acetabular anteversion angle,acetabular abduction angle,pain score,mobility of hip joint,walking ability score in the obesity group were (17.8 ± 1.2) °,(40.9 ± 3.4) °,(1.26 ± 0.61) points,(95.43 ± 7.89) °,(8.10 ± 0.27) points,respectively,which in the overweight group were (16.7 ± 3.3) °,(42.9 ± 2.9) °,(1.23 ± 0.58) points,(96.78 ± 3.22) °,(8.20 ±0.92) points,respectively,which in the normal group were (15.8 ± 2.7) °,(43.9 ± 5.1) °,(1.24 ± 0.78) points,(97.12 ± 6.44)°,(8.20 ± 0.48)points,respectively.The difference of acetabular abduction angle among the three groups was statistically significant (F =9.803,P =0.002).In the obesity group,there were two cases of incision infection,two cases of deep venous thrombosis and one case of pulmonary complication,the incidence rate of complications was 5％.In the overweight group,there was one case of superficial incision infection,and one case of deep vein thrombosis,the incidence rate of complications was 2％.In the normal group,there was one case of deep venous thrombosis,the incidence rate of complications was 1％.The difference of incidence rate of complications among the three groups was statistically significant (x2 =15.31,P ＜ 0.01).Conclusion Obesity increases the surgical risk of SuperPATH total hip replacement,and more attention should be attached to perioperative and post-operative treatment for such patients.
