Spinal Fusion, Total Hip Replacement
Conditions
Brief summary
The purpose of the study is to explore the long term functional status of people who have had both a spinal fusion procedure and a total hip replacement.
Detailed description
The purpose of the study is to explore the long term functional status of people who have had both a spinal fusion procedure and a total hip replacement. Studies have found that those who have received spinal fusion may have worse outcomes following a total hip replacement than those who have not received a spinal fusion. The information obtained from this study will allow surgeons and researchers to better understand why some who've had a spine fusion have more complications post total hip replacement compared to those who did not have spinal fusion surgery.
Interventions
DIAGNOSTIC_TESTX-Ray Imaging
X-Ray imaging in the following positions: Lateral standing, lateral seated, standard standing AP pelvis and AP pelvis lying down.
OTHERGait Analysis
Certain patients may be asked to participate in a motion analysis procedure at the Human Movement Laboratory at the University of Ottawa. This procedure takes approximately 1.5 hours and you will only be asked to participate in the motion analysis procedure once. Participants will change into a custom-designed tight body suit, which has reflective markers on its surface for infrared video capture. Participants will then have pairs of surface electromyography (EMG) electrodes placed on certain areas of the skin on the legs and on the back. Wearing the EMG electrodes and marker suit, participants will perform 5 trials of walking on a level walkway, walking up and down a 3-step staircase, sitting from a standing position, and standing from a seated position.
