  Purpose

Compare the surgical use of Topaz with the Standard Of Care in the treatment of Greater Trochanteric Pain Syndrome (a type of hip pain). The hypothesis is that there is a difference between the two treatment groups.


Condition Intervention Phase
Greater Trochanteric Pain Syndrome
Hip Pain
 Device: Topaz
Procedure: Iliotibial band release and trochanteric bursectomy
 Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Outcomes Assessor)
Primary Purpose: Health Services Research
Official Title: A Randomised, Controlled, Double-blind Clinical Investigation on the Efficacy and Safety of Radiofrequency Micro Debridement, Topaz, in Recalcitrant Greater Trochanteric Pain Syndrome (GTPS) vs. Standard of Care

Primary Outcome Measures:
  • Modified Harris Hip Score [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    This is a patient questionnaire used to evaluate hip function following surgery.


Secondary Outcome Measures:
  • The Western Ontario and McMaster Universities Arthritis Index [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    This is a patient questionnaire used to evaluate rheumatic symptoms, stiffness, pain and how it affects the ability to function.

  • Visual Analogue Scale [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    This is a patient questionnaire designed to evaluate pain.

  • SF-12 Health Survey [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    This is a patient questionnaire measuring health-related quality of life.

  • Duration of surgery between two treatment groups [ Time Frame: 1 day ] [ Designated as safety issue: No ]
    The total length (time) of surgery will be compared between the two groups.

  • Ultrasound findings [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Adverse events [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Estimated Enrollment: 66
Study Start Date: April 2012
Estimated Study Completion Date: September 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
