Fracture neck of femur has been recognised since the time of Hippocrates and is a common orthopaedic problem in old age and they have a tremendous impact on both the health care system. Despite marked improvements in the implant design, surgical technique and patient care, they still remain an unsolved fracture as for as treatment and results are concerned among the orthopaedic fraternity around the world.
By this study we will be able to assess whether bipolar prosthesis really functions as its name suggests or vice versa as the literature suggests.
Materials and Methods: Consist of 2 parts. Part I is a (prospective study) in which Patients who undergone Bipolar hemiarthroplasty for fracture neck of femur at PSG Hospitals were included in the study after obtaining their consent during the period of December 2011 to June 2013.
Part II was a retrospective study where we took a data of patients who were operated earlier in our institute and had completed atleast 2 years of follow-up.
Results and Discussion: With this study we found that for effective functioning of bipolar prosthesis IPJ movement remains a vital cog in the success of the bipolar prosthesis. In this study we found that there is good amount Inter-prosthetic joint movement of bipolar prosthesis at short – term and mid - term follow-up. The functional outcome is also good when Inter-prosthetic joint movement is more than 25%.
