Durom(R) Hip Resurfacing System Multicenter Trial

This study has been completed.
Information provided by (Responsible Party):
Zimmer Biomet Identifier:
First received: September 2, 2008
Last updated: April 2, 2013
Last verified: April 2013
The purpose of the study is to gather clinical information on the safety and efficacy of the resurfacing devices in the young, active patient with advanced hip disease. Study enrollment has been temporarily suspended due to a change in the surgical technique.

Condition Intervention Phase
Advanced Hip Disease Device: Durom Hip Resurfacing System Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Durom(R) Hip Resurfacing System Multicenter Trial

Further study details as provided by Zimmer Biomet:

Primary Outcome Measures:
  • Device Survival [ Time Frame: All post-op visits until last patient enrolled reaches 2 year follow-up ]

Secondary Outcome Measures:
  • Efficacy [ Time Frame: 6 month post-op and annually until last patient reaches 2 year follow-up ]

Enrollment: 40
Study Start Date: June 2007
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Hip resurfacing devices in the young, active patient with advanced hip disease instead of traditional total hip arthroplasty.
Device: Durom Hip Resurfacing System
Hip resurfacing devices in the young, active patient with advanced hip disease instead of traditional total hip arthroplasty.
Other Name: Hip Reserfacing

Detailed Description:
Safety will be evaluated based on the frequency and incidence of any device related adverse events or unanticipated adverse device events. The efficacy will be measured by comparing the overall functional performance based on the Harris Hip Score, implant survivorship, and radiographic parameters, including radiolucencies, osteolysis, stem subsidence, cup migration, and change in cup angle and a change in the femoral shaft angle.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
