Examining Effects of Spinal Fusion on Outcomes Following Total Hip Replacement

26 de marzo de 2020 actualizado por: Wade Gofton, Ottawa Hospital Research Institute

Examining Effects of Spinal Arthrodesis on Outcomes Following Total Hip Arthroplasty

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.

Descripción general del estudio

Descripción detallada

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.

Población de estudio

Approximately 70 patients who underwent total hip arthroplasty (THA) and spine fusion (SF) surgery will be called by the surgeon or research team and asked if they wish to participate in the study. A second group of approximately 45 patients who have only had a THA (and no SF) will serve as a comparison group. A third group of approximately 45 patients who have only had an SF surgery (and no THA) will also be recruited.

Cohortes e Intervenciones

Grupo / Cohorte
Intervención / Tratamiento
Spine Fusion and Total Hip Replacement
Any patient who has undergone spine fusion (SF) and total hip arthroplasty (THA). Patients will undergo x-ray imaging and complete functional assessment questionnaires. Patients may additionally be asked to participate in a gait analysis in a Human Movement Laboratory.
X-Ray imaging in the following positions: Lateral standing, lateral seated, standard standing AP pelvis and AP pelvis lying down.
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.
Total Hip Replacement Group
Any patient who has had THA only (no spine fusion surgery). Patients will undergo x-ray imaging and complete functional assessment questionnaires. Patients may additionally be asked to participate in a gait analysis in a Human Movement Laboratory.
X-Ray imaging in the following positions: Lateral standing, lateral seated, standard standing AP pelvis and AP pelvis lying down.

X-Ray imaging in the following positions: Lateral standing, lateral seated, standard standing AP pelvis and AP pelvis lying down.
