Abstract: 
Hip fractures are one of the most common injuries, mainly seen in the elderly in the emergency setting. It can also be seen in young patients like athletes or one who met with a high energy trauma. The objective of treatment of NOF fractures in mobile elderly population is early restoration of pre-morbid walking ability and quality of life.
The modular prosthesis allows adjustment of neck length with interchangeable stems. It can be converted to a total hip replacement easily because only the acetabular component is added. Cemented prostheses are associated with increased incidence of peri-operative morbidity like hemodynamic instability, deep vein thrombosis, cardiopulmonary complications, etc and mortality. Cementless stems do not lead to such complications and therefore no chance of so-called ‘cement reaction’ or bone cement implantation syndrome (BCIS).
The purpose of this study is to assess the functional outcome and quality of life scores in patients with intracapsular fracture of the femoral neck treated by uncemented hemiarthroplasty (UCHA) using modular bipolar prosthesis.
Materials and Methods: Patients having femoral neck fracture were admitted to Bapuji Hospital and Chigateri General Hospital, attached to J.J.M. Medical College, Davangere were taken for this study after obtaining their consent. This is a prospective study from October 2019 to October 2021.
Results: Data was collected based on detailed patient evaluation with respect to history, clinical examination and radiological examination. Out of the 20 cases, all patients were available for follow up till one year which was taken as a basic pre-requisite for inclusion in the study. In our study, the final Harris Hip Score calculated at the end of one year follow-up averaged 85.4 with the maximum score being 95 and the minimum score being 63. Our study data showed that 8 patients (40%) achieved excellent result at the end of 1 year of the surgery, 7 patients (35%) achieved Good result, 3 patients (15%) achieved fair result and 2 patients (10%) achieved poor result. Overall, 75% of the patients achieved an excellent or good result. Our results are comparable with standard studies done in context of NOF fractures treated with bipolar hemiarthroplasty. Our duration of follow-up being one year is short enough in assessing the longevity and endurance of the modular bipolar prosthesis used.
Conclusion: Uncemented Modular Bipolar hemiarthroplasty for femoral neck fractures in the elderly permits early return to pre-morbid life as it provides better range of movement, freedom from pain and is not associated with any untoward cardiac event in the peri-operative period. It can be considered a treatment option in this select group.
