Mechanism of Unstable Inter-trochanteric Fractures in the Elderly

The aim of this prospective comparative study is to analyse the short term follow-up results of unstable inter-trochanteric fractures in the elderly treated with Bipolar hemi-arthroplasty and Dynamic hip screw fixation done in our institution from March 2017 to October 2018. Proximal femoral fractures in the elderly individuals have a tremendous impact on both the health care system and society. Upon treatment of inter-trochanteric factures with conservative management, it usually unites with a mal-union, non-union and with shortening, but the problem of non –union in trochanteric fractures has less incidence. Because of complications associated with prolonged recumbency and its associated morbidities. Primary hemiarthroplasty in these patients provides for adequate fixation and early mobilization. It alleviates pain and improves function. It also prevents post-operative complications such as pneumonia, lung atelectasis and pressure sores. From our clinical observation we would suggest that unstable intertrochanteric fractures in elderly result most frequently from accidental fall (52.5%), being the most common described mechanism of injury.
