Management of Fracture Neck of Femur with Cemented Bipolar Prosthesis.

ABSTRACT

Background: In this clinical study, 20 cases of intracapsular fracture neck of femur in elderly patients of age 60 years and above were treated by hemiarthroplasty using cemented bipolar endoprosthesis. This study was conducted at the Dept. of Orthopedics, Sri Siddhartha Hospital, Tumkur, Karnataka, between October 2010 and March 2012. The results and follow-up were evaluated. Material and methods: The cases were followed-up for 6 months and the short-term functional results were analyzed by using modified Harris hip scoring system. Results: At the end of 6 months after surgery, the functional results were analyzed in 20 cases. All patients were in the age group of 60-82 years with mean average age of 75 years. Thirty-five percent of the patients had a Garden type III fracture radiologically, while 60% had a Garden type IV and one patient was diagnosed with a nonunion fracture neck of femur. In 75% of cases, the mode of injury was trivial trauma. Some of the complications observed were superficial infection of the wound or a limb length discrepancy, following the procedure. There were 50% excellent results and 30% good results. Conclusions: The success of hemiarthroplasty no doubt depends on preoperative planning and proper attention to surgical details to achieve the optimum biomechanical stability. This study showed that the final functional outcomes were dependent on the presence of associated comorbidities and the optimum postoperative rehabilitation of the patient following surgery.
