Benefit of Orthopedic Navigation in the ARThroplasty of the Hip

Randomised Controlled Double-blind Monocenter Therapy Study Validating the Benefit From Information Provided by Image Free Navigation System on the Precision of the Placement of Acetabular Component in Patients Undergoing Primary THA

• Status: Completed

Summary

This study was initiated to investigate the impact of the computer based image free navigation on the precision of the cup implantation. The implantation of the acetabular component (cup) is known to be a critical step in hip endoprosthetics. The cup position influences significantly the function, the absence of pain and the longevity of the artificial hip joint. The image free navigation system OrthoPilot is used to control the positioning of the cup during surgery.

Conditions

• Osteoarthritis, Hip
• Arthritis, Rheumatoid
• Femur Head Necrosis

Interventions

Type	Name	Description
PROCEDURE	Manual Intervention	Implantation of acetabular component without the use of the navigation system information
PROCEDURE	Navigated Intervention	Navigated implantation of acetabular component using OrthoPilot image free navigation system
