Abstract:Objective To discuss the effect of mini-incision total hip arthroplasty (THA) on joint function and stress stage in patients with femoral fracture. Methods Totally 100 patients with femoral fracture were selected from December 2013 to December 2016 in our Hospital, according to the treatment method, all patients were divided into group A and group B, 50 cases in each group. group A was given THA treatment, while group B was given small incision THA treatment, The intraoperative blood loss, operative time, postoperative drainage flow, hospital stay time, complication, joint function and preoperative, postoperative serum cortisol (COR), fasting blood glucose (ACTH) levels were statistically anylyzed. Results The intraoperative blood loss, postoperative drainage flow, hospital stay time, complication rate of group B were significantly lower than those of group A, the differences were statistically significant (P?< 0.05). but the operation time, joint function excellence rate of two groups were basically the same, which were not significant different (P?>?0.05). The postoperative serum COR and ACTH levels of group A and group B were significantly higher than those of the preoperative ones, and the postoperative serum COR and ACTH levels of group B were significantly lower than those of group A, the differences were statistically significant (P?0.05). Conclusions Small incision THA has a good curative effect in femoral fracture, and it can effectively reduce the surgical trauma and postoperative stress reaction of patients, which is beneficial to physical recovery and reduction of complications in patients. It’s worthy of further clinical promotion.
