Methods: This study retrospectively analyzed 60 elderly patients with unstable intertrochanteric fractures treated with PFNA and artificial femoral head replacement from 2015.06 to 2018.06, of which 34 were in the PFNA group (Group A) and 26 in the artificial femoral head replacement group (Group B). Statistical analysis of relevant surgical indicators such as surgical time, intraoperative blood loss, postoperative blood transfusion, postoperative time to landing, postoperative infection rate, hospital stay, number of secondary operations, postoperative VAS score, and postoperative Hip function score comparison. Results: All 60 patients were followed up for 1 - 24 months. Compared with the artificial femoral head replacement group, the operation time of PFNA group was shorter, the blood loss during operation was less, and the difference was statistically significant (P 0.05). Conclusion: The hip joint function and pain scores of the artificial femoral head replacement group in the early and follow-up periods are better than those of the PFNA group. The artificial femoral head replacement is more suitable for the treatment of elderly unstable intertrochanteric fractures.展开更多

In addition, high rates of complications after long-term RSA have been reported, suggesting that RSA should be limited to elderly patients, especially those who are older than 70 years old. Since 2001, we have developed a strategy of rotator cuff reconstruction with muscle transfer and humeral head replacement (HHR), using smaller humeral prostheses, in cuff tear arthropathy patients. The aim of the present study was to investigate the clinical outcome of our strategy in patients under 70 years of age who had irreparable rotator cuff tears and osteoarthritis. Materials and Methods: A total of 25 shoulders of 25 patients under 70 years of age (males, 15;females, 10) with irreparable cuff tears were treated with HHR and cuff reconstruction. The average age at the time of surgery was 64.3 years (range, 55 - 69) and the average follow-up period was 38.7 months (range, 24 - 72). The cuff defect was repaired using a partial subscapularis transfer in 14 shoulders;nine shoulders required a latissimus dorsi transfer, one required a pectoralis major transfer, and one required both a latissimus dorsi and a pectoralis major transfer. Clinical outcomes were assessed with the range of motion (ROM), UCLA score, Japanese Orthopaedic Association (JOA) score and postsurgical complications. Results: Shoulder pain was diminished in all patients after surgery. The preoperative UCLA and JOA scores were 13.1 and 47.0 respectively, improving to 28.6 and 81.5 respectively after surgery. Active forward flexion has improved from an average of 89.0° to 138.8°, and the ER improved from an average of 16.2° to 33.2°. No complications occurred after surgery. Conclusion: Anatomical reconstruction using smaller head humeral prostheses yielded favorable results and less complication, compared with RSA. Considering another advantage of ability to retain glenoid bone stock, the current procedure can be a useful option for irreparable rotator cuff tears with OA in patients under 70 years old.展开更多

Methods: Fifty cases of elderly femoral neck fracture from January 2018 to January 2019 in our hospital were selected. Patients were randomly divided into two groups with 25 cases in each group by random number table. Patients in the femoral head group were treated with artificial femoral head replacement, while patients in the total hip group were treated with total hip replacement. The drainage volume, bleeding, total operation time, evaluation scores of QOL scale before and after treatment, Harris hip joint status score and complication rate were compared between the two groups. Results: the operation time, bleeding and drainage volume of the total hip group were higher than those of the femoral head group, P < 0.05. There was no significant difference in complications between the two groups (P > 0.05). After treatment, evaluation scores of QOL scale and Harris hip joint status score of the patients were higher than those of the femoral head group, P > 0.05. Conclusion: comparing total hip replacement and artificial femoral head replacement in the treatment of elderly femoral neck fracture, the trauma of artificial femoral head replacement is relatively simple and less bleeding, but in the long term, total hip replacement can improve the hip joint function and quality of life of patients better.展开更多

The functional outcomes of arthro- plasty with cemented titanium implants of radius in the treatment of radial head fractures （Mason Type Ⅲ： 6; Mason Type Ⅳ： 4） in l0 consecutive patients （mean age, 38 years） were evaluated over a mean time of 23.7 months （18-31 months）. The patients were assessed on the basis of physical examination, functional rating （Mayo） and radiographic findings. The parameters evaluated included motion, stability, pain, and grip strength. Five patients were considered to have excellent results, 4 patients had good results and l patient had fairly good results. There were no cases of infection, prosthetic failure, heterotopic ossification or dislocation. When medial collateral ligament was injured, radial head became the main stabilizing structure of the elbow. Titanium radial head implant may provide the stability similar to that of native radial head. We believe that titanium radial head im- plants may be indicated for the Mason Type Ⅲ and Mason Type IV radial head fractures.展开更多
