Thigh size in obese people causes dislocations in THRs – A medical Study

Updated 10/20/2012 University of Iowa researchers have determined that thigh size in obese people is a reason their hip implants are more likely to fail…

…In a study, the team simulated hip dislocations as they occur in humans and determined that increased thigh girth creates hip instability in morbidly obese patients (those with a body mass index (BMI) greater than 40). The researchers propose that surgeons modify surgical procedures to minimize the chance of dislocation in obese patients and consider other designs for hip replacement implants…

The National Institutes of Health, the Veterans Administration, and the National Center for Resource Resources funded the research.
