Dislocation Precautions

August 5, 2022 updated by: Ottawa Hospital Research Institute

Impact of Dislocation Precautions on Fear and Function in Patients Undergoing Hip Replacement

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
OTHER: Anterior Approach Precautions
This group receives precautions and have a total hip arthroplasty with a posterior approach.
Procedure: Anterior Approach Precautions
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.
OTHER: Posterior Approach Precautions
This group receives precautions and have a total hip arthroplasty with a posterior approach.
Procedure: Posterior Approach Precautions
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.
OTHER: Anterior Approach No Precautions
This group receives does not precautions and have a total hip arthroplasty with an anterior approach.
Procedure: No Precautions
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.
OTHER: Posterior Approach No Precautions
This group receives does not receive precautions and have a total hip arthroplasty with a posterior approach.
Procedure: No Precautions
For the non-precautions group, there will be no mention of precautions by any providers before, during, and after surgery.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Oxford Hip Score
Time Frame: Week before surgery to 6 months after surgery
Assess function of the hip
Week before surgery to 6 months after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Tampa Scale for Kinesiophobia
Time Frame: Week before surgery to 6 months after surgery
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.
Week before surgery to 6 months after surgery
Change in Forgotten Joint Score
Time Frame: 6 weeks after surgery to 6 months after surgery
This measures awareness of a replaced joint
6 weeks after surgery to 6 months after surgery
Change in EQ-5D-5L
Time Frame: Week before surgery to 6 months after surgery
This measures general health
Week before surgery to 6 months after surgery
Canadian Patient Experience Survey - Inpatient Care (CPES-IC)
