Brief Summary

One of the leading causes of hip arthritis is femoro-acetabular impingement which means the hip joint is deformed such that the hip joint jams in the front when the hip is bent all the way forward. This can lead to significant damage to the hip joint and may result in the need for a total hip replacement. However, if detected early, this deformity can be treated surgically by reshaping the hip joint. If the hip joint could be better visualized before surgery, then surgeons would be able to develop less invasive surgical techniques to correct this deformity.

Conditions

Femoroacetabular, Impingement

Keywords

femoroacetabular, impingement

Outcome Measures

Primary Outcomes (1)

• Validation of kinematic model of hip joint

  Development of a kinematical model of the hip joint to simulate virtual joint motion. This will be done by using automatic segmentation using the CT data to generate models.

  Within 6 months of recruitment

Secondary Outcomes (2)

• Joint Kinetics

  24 months

• Muscle Activity

  24 months

Study Arms (2)

FAI patients

ACTIVE COMPARATOR

This group consists of participants diagnosed with femoroacetabular impingement that are undergoing surgical correction.

Procedure: Motion analysis; Diagnostic Test: Computed Tomography

Control

PLACEBO COMPARATOR

This group consists of healthy control participants with no hip problems.

Procedure: Motion analysis; Diagnostic Test: Computed Tomography

Interventions

Motion analysis PROCEDURE

Participants will undergo a motion analysis procedure: a dynamic assessment of the movement in their hip.

Control; FAI patients

Computed Tomography DIAGNOSTIC_TEST

Participants will undergo computed tomography (CT) scan of their hip.

Control; FAI patients

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• All participants (patients and controls) must be between the ages of 18 and 55, with a BMI less than 35.
• The patients must have a probable diagnosis of femoro-acetabular impingement (FAI). Their hip pain must have been ongoing for at least 3 months. The controls must have a normal hip as defined by AP pelvis radiographs.

You may not qualify if:

• Participants (patients and controls) will be excluded if they are pregnant, have a knee injury or replacement, or history of childhood hip disease. Patients will be excluded if have they have arthritis, previous fracture or trauma to the hip, previous hip surgery, dysplasia, or avascular necrosis. Controls will be excluded if they have hip pain.
