The correlated risk factors for the infection after a total hip replacement / 中华老年医学杂志

Objective To explore the correlated risk factors for the infection after a total hip replacement.Methods A retrospective analysis was conducted in 200 elderly patients undergoing total hip replacement in our hospital from January 2012 to December 2015.A single factor analysis and a multivariate Logistic regression analysis were used to identify the associated risk factors.Results Among 200 patients,the incidence rate of postoperative infection was 7.5 ％.Based on the single factor analysis,diabetes,preoperative serum protein level,smoking,operation time,intraoperative bleeding volume,postoperative drainage time,long-term steroid use,and history of hip surgery were closely associated with the infection after total hip replacement(all P＜0.05).Further multivariate Logistic regression analysis showed that diabetes,smoking,long operation time,long postoperative drainage time,long history of steroid use,and history of hip surgery were independent factors for the infection after total hip replacement(all P＞0.05).Conclusions Diabetes,smoking,long operation time,long drainage time,long term hormone usage,and history of hip joint surgery are independent factors associated with the infection after total hip replacement.Clinically,these risk factors targeting prevention and treatment strategies can be adopted to reduce the incidence of infection.

Efficacy analysis on hip replacement for hip-joint diseases with Parkinson disease / 中国骨伤

<p><b>OBJECTIVE</b>To explore clinical efficacy of hip replacement for hip-joint diseases with Parkinson disease.</p><p><b>METHODS</b>From December 2011 to December 2016, 18 patients with hip-joint diseases with Parkinson disease treated by hip replacement, including 8 males and 10 females aged from 59 to 87 years old with an average of 71 years old. Among them, 3 cases were developmental dysplasia of hip, 3 cases were femoral head necrosis and 12 cases were femoral neck fracture. All patients manifested with obvious pain and limitation of stepping ability. Postoperative complications were observed and Harris score were used to compare hip joint function after operation.</p><p><b>RESULTS</b>The incision were healed well, and pain were alleviated or disappeared, and hip joint function were improved. Eighteen patients were followed up from 1 to 3 years with an average of 2.3 years. At the latest follow up, 14 cases recovered freedom-walk, 2 cases could walk with walking stick, 1 case could walk with walking aid and 1 case was died. Among 18 patients, 2 cases were occurred dislocation, and 1 case were died for cardiac disease at 3 months after operation. Four patients were occurred slight pain. There were significant differences in Harris scores among preoperative (41.7±1.4), 6 months after operation(80.1±5.4) and the final follow-up (83.4±2.1), and 10 cases got excellent result, 4 good, 1 fair and 2 poor.</p><p><b>CONCLUSIONS</b>Application of hip replacement for hip-joint diseases with Parkinson disease is a safe and effective clinical therapy, and has advantages of less complications and rapid recovery of hip joint function.</p>
