Subject Specific

Low-trauma hip fracture, usually caused by fall from standing height, has become a main source of morbidity and mortality for the elderly. Factors affecting hip fracture include sex, race, age, body weight, height, body mass distribution, etc., and thus, hip fracture risk in fall differs widely from subject to subject. It is therefore necessary to develop a subject-specific biomechanical model to predict hip fracture risk. The objective of this study is to develop a two-level, image-based, subject-specific biomechanical model consisting of a whole-body dynamics model and a proximal-femur finite element (FE) model for more accurately assessing the risk of hip fracture in lateral falls. Required information for constructing the model is extracted from a whole-body and a hip DXA (Dual Energy Xray Absorptiometry) image of the subject. The proposed model considers all parameters subject-specifically, which will provide a fast, accurate, and non-expensive method for predicting hip fracture risk.

Necrosis Of Femoral Head

Dislocation after primary Total Hip Arthroplasty is devastating complication which may lead to neurovascular damage if not treated urgently. Posterior approach to hip is most commonly used worldwide. It said to have increased chances of dislocation postoperatively as compared to other approaches according to literature but still a debatable topic of discussion. In our study , we retrospectively studied 189 patients operated for primary THA in tertiary care centre fullling inclusion criteria. These patients were operated by same surgeon with posterior approach and uncemented implant with 28mm femoral head .Demographic data of patients and incidence of dislocation studied. Our observations and results found out that male patients are more common and are of young age group who undergone THA. Most common indication for surgery was Avascular necrosis of femoral head. Out of 189 , only 3 patients had episode of dislocation. With our study , we conclude that posterior approach to hip is safe if done by experienced surgeon with ideal implant positioning ,meticulous soft tissue repair & proper patient counseling for post-op rehabilitation
