Ipsilateral Intracapsular Hip Fracture 2 Years after Fixation of Extracapsular Fracture by Dynamic Hip Screw

INTRODUCTION: Sustaining an intracapsular fracture in a hip which was previously fixed with dynamic hip screw for extracapsular fracture, is a very rarely reported occurrence. We present one such case in order to discuss the presentation and management of this fracture. We have also reviewed the literature and pooled the previously reported cases to look at potential cause & risk factors. CASE REPORT: A 92 year old female, presented with new onset hip pain following a trivial injury. Couple of years back, she had sustained an extracapsular fracture on same side which was treated by DHS fixation. Further investigations confirmed a de-novo fracture which was treated by removal of DHS and cemented bipolar hemiarthroplasty. CONCLUSION: This complication might not be as rare as earlier thought to be. All patients, especially elderly females who present with new onset hip pain following DHS fixation of their hip fracture previously must be evaluated for a de-novo intracapsular fracture. On confirmation of diagnosis, they can be treated by removal of dynamic hip screw and hemiarthroplasty as most of these are low demand elderly patients.
