Defining Optimum Cup Orientation for Hip Replacements Taking Into Account the Individual's Anatomy and Movement Patterns

A Prospective Study to Define Optimum Cup Orientation in Hip Arthroplasty Accounting for the Individual's Anatomy and Movement Patterns

• Status: Unknown
• Phase: N/A
• Study type: Interventional

• Healthy volunteers: Not accepted

Summary

The purpose of this study is to investigate and determine the optimal zone for implanting the cup component (the ball that sits in the joint socket) in a total hip replacement. Enrolled participants will have a series of X-rays analyzed before surgery to identify their individual optimal zone or cup orientation. This information will be provided to the operating surgeon, who may use this information to influence the placement of the cup implant. Follow-up X-rays taken after surgery will determine if the cup is within the suggested optimal zone. Questionnaires will be completed before and after surgery, and data on complications or issues with the surgery (including incidents of dislocation) will be collected after surgery.

Conditions

• Hip Arthritis
• Hip Osteoarthritis

Interventions

Type	Name	Description
PROCEDURE	Optimum Cup Orientation	Participants will have X-rays taken before surgery to determine the target optimal zone for orientation of the cup implant, using EBRA software. The surgeon may or may not implant in this target zone, depending on what they believe is in the patient's best interest. X-rays will be taken at 12 months after surgery to determine if they target cup orientation was achieved.
