Ultrasound-Guided Hip Joint Cooled Radiofrequency Denervation

Status Withdrawn

Clinical Trial 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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
