Ultrasound-Guided Hip Joint Cooled Radiofrequency Denervation
Study Details
Study Description
Brief Summary
Hip osteoarthritis (HOA) is a common cause of pain and disability in aging population. Conservative treatment is based on lifestyle modifications, physical therapy, analgesic and anti-inflammatory medications and intra articular injections. This Prospective Pilot Study aims at investigating the efficacy of Ultrasound-Guided Cooled Radiofrequency Hip Denervation as a treatment offered to patients with HOA.

Detailed Description
Radiological prevalence of HOA is very high. Hip denervation (HD) is a known palliative procedure that was initially performed as an open surgery. The role of the obturator, femoral and sciatic nerves in hip joint innervation was discovered. Several small clinical and anatomical studies addressed feasibility and benefits of the radiofrequency hip denervation (RFHD). Ultrasound guidance may eliminate equivocality of previously published techniques and provide precise image guidance as it a is logical and anatomically sound approach when procedural targets include soft tissue, such as nerves, tendons and joint capsule. None of these structures can be localized under routine fluoroscopy. Ultrasound is a bedside imaging tool that has been accepted as safe and reliable. In two meta-analyses, the use of real-time two-dimensional ultrasound for the placement of CVCs substantially decreased mechanical complications and reduced the number of attempts at required cannulation and failed attempts at cannulation compared with the standard landmark placement. Pertinent to the proposed study, recent systematic review and meta-analysis of the accuracy of US-guided versus landmark-guided hip joint injections revealed that US-guided injections are significantly more accurate than those that are landmark-guided. The significance of this study lies in its potential to improve functional activity and pain control in patients with HOA. Also, it may eventually lead to a decrease in patients resorting to Total Hip Arthroplasty (THA) as an ultimate end solution for HOA.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Ultrasound-Guided Hip Denervation This is a pilot study. 15 Hip Osteoarthritis patients with chronic pain will be recruited in this pilot arm. These will undergo Ultrasound-Guided Cooled Radiofrequency Hip Denervation as intervention. |
Device: Ultrasound-Guided Cooled Radiofrequency Hip Denervation
Light neuroleptic anesthesia and skin preparation will be performed. Under Ultrasound guidance, an active probe will be inserted. Sensory and motor stimulation will be administered. Anteroposterior fluoroscopy image will be recorded. Lesioning of articular branches of femoral and obturator nerves via radiofrequency will be performed after lidocaine injection. WOMAC, EQ-5D and SF-12 questionnaires will be used for measuring outcomes postoperatively.

Outcome Measures
Primary Outcome Measures
- Western Ontario and MacMaster Universities Osteoarthritis Index (WOMAC) Score [12 months]
A questionnaire designed to assess pain, stiffness, and physical function in patients with hip and/or knee osteoarthritis (OA)1 The WOMAC consists of 24 items divided into 3 subscales: Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing Stiffness (2 items): after first waking and later in the day Physical Function (17 items): stair use, rising from sitting, standing, bending, walking, getting in / out of a car, shopping, putting on / taking off socks, rising from bed, lying in bed, getting in / out of bath, sitting, getting on / off toilet, heavy household duties, light household duties.
Secondary Outcome Measures
- Short Form (12) Health Survey (SF-12) [12 months]
A generic, multipurpose short-form survey with 12 questions selected from the SF-36 Health Survey which, when combined, scored and weighted, results in two scales of mental and physical functioning and overall health-related quality of life.
- EQ-5D [12 months]
EQ-5D is a standardised instrument for use as a measure of health outcome.It is applicable to a wide range of health conditions and treatments, it provides a simple descriptive profile and a single index value for health status. It is primarily designed for self-completion by respondents and is ideally suited for use in postal surveys, in clinics and face-to-face interviews. It is cognitively simple, taking only a few minutes to complete. Instructions to respondents are included in the questionnaire.
