A prospective study of functional outcome of intracapsular femur neck fractures treated with bipolar prosthesis

Aims: In this clinical study forty cases of intracapsular fracture neck of femur in elderly patients above the age of 60 years treated by bipolar hemiarthroplasty and were followed up and functional results were analysed with the objectives, to study the age and sex incidence of fracture neck of femur, quality of life after hemiarthroplasty, morbidity and mortality associated with the procedure, recovery of physical, social and vocational independence, number of days of stay in hospital and associated complications. Methods: Forty cases of fracture neck of femur in elderly patients above the age of 60 years treated by hemiarthroplasty using bipolar prosthesis between November 2017 to May 2019 were selected according to inclusion and exclusion criteria. Cases were followed up for 6 months and the short term functional results were analysed by using modified Harris hip score. Results: Most of the patients were in the age group of 60 to 70 years with mean average age of 69.2 years. Females were predominant. In 62.5 percent cases mode of injury was trivial trauma. Associated comorbidities hypertension, diabetes mellitus and anaemia were common. The complications observed were superficial infection of the wound, bedsore, periprosthetic fracture and posterior prosthetic dislocation. There were 30% excellent results and 45% good results.Conclusion: The success of hemiarthroplastydepends on preoperative planning and attention to surgical details to achieve the optimum biomechanical stability. Bipolar hemiarthroplasty for fractures neck femur provides betterrange of movement, freedom from pain and more rapid return to unassisted activity with an acceptable complication rate. The end functional results depend on the age of the patient, associated co-morbidity and optimum post-operative rehabilitation. Early functional results are satisfactory.
