Summary

The objective of this study is to analyze subjects having a normal hip and compare the in vivo kinematics to subjects requiring a total hip arthroplasty (THA) due to having a diseased hip and then later post-operative to their implanted hip. Ten subjects will have a normal hip, ten hips will be diseased, requiring a THA and then those ten diseased hips will be re-analyzed at least six months post-operatively after implantation of a THA.

Conditions

• Hip Injuries

Interventions

Type	Name	Description
DEVICE	DePuy Synthes total hip arthroplasty
RADIATION	Computer tomography	Computer tomography (CT) scan of the hip for creation of bone models.
RADIATION	Fluoroscopy surveillance	Fluoroscopy evaluation of the hip during gait (level walking), chair rise, and ramp ascent and descent activities. Sound/vibration data will be collected simultaneously via non-invasive sensors attached to the hip joint.
