Dislocation Precautions

Ottawa Hospital Research Institute212 enrolled

Overview

This study is looking at the impact of giving patients precautions, or restrictions for movement, when undergoing a total hip replacement. Have of the participants will receive precautions, while the other half will not receive any precautions.

Patients undergoing hip replacements are often told by health care providers to avoid specific positions and activities to decrease the risk of their hip dislocating following their surgery. This, however, results in patients becoming more fearful of moving and leads to limitations in their function and decreased quality of life. Previous research has shown that hip dislocations following surgery are most commonly attributed to poor implant position rather than the actions of the patients. Teaching precautions takes up healthcare resources and may use finances that are not necessarily required. This study aims to compare groups with half receiving precautions and half not receiving precautions, to assess the impact of precautions on the patients' quality of life.

Interventions

Posterior Approach PrecautionsPROCEDURE

These patients will be advised not to bend their leg or trunk more than 90 degrees, avoid crossing the leg or crossing midline, and rotating the leg inwards. Patients will also be instructed to put a pillow in between their legs while sleeping for 6 weeks and to avoid bathing for 6 weeks.

Anterior Approach PrecautionsPROCEDURE

These patients will be advised to avoid extending the leg back, rotating the leg outwards, and lifting their bottom when lying down after their surgery for 6 weeks.

No PrecautionsPROCEDURE

For the non-precautions group, there will be no mention of precautions by any providers before, during, and after surgery. No equipment will be given, but a list of self-care equipment will be available for 'comfort' purposes. Patients will be instructed to avoid bathing for 4 weeks. All groups will have instructions to use a walking aid and a toilet seat if needed, to weight-bear as tolerated, and to avoid driving for 3 weeks.

Outcomes

Primary Outcomes

Change in Oxford Hip Score

Assess function of the hip

Time frame: Week before surgery to 6 months after surgery

Secondary Outcomes

Change in Tampa Scale for Kinesiophobia

This assesses kinesiophobia, using a 17 item scale with each item using a 4 point Likert scale . The final score is the sum of all questions except for 4, 8, 12 and 16 which has their score inverted before being added. The final score ranges from from 17-68 points with 68 being the highest degree of kinesiophobia.

Time frame: Week before surgery to 6 months after surgery

Change in Forgotten Joint Score

This measures awareness of a replaced joint

Time frame: 6 weeks after surgery to 6 months after surgery

Change in EQ-5D-5L

This measures general health

Time frame: Week before surgery to 6 months after surgery

Canadian Patient Experience Survey - Inpatient Care (CPES-IC)

This will measure the patients' experience.

Time frame: At 2 weeks after surgery
