Objective - to compare the effectiveness of radiofrequency denervation (RFD) and conservative treatment of patients with hip degenerative diseases. Material and methods. 66 patients with various stages of hip degeneration were followed up for 12 months, including 36 patients who underwent RFD and 30 patients of control group with conservative treatment. Treatment results were assessed using Visual Analogue Scale (VAS) and Harris Hip Score before treatment, during the first day, 2 days later, as well as at 1, 6 and 12 months. Results: RFD patients demonstrated significantly better results compared with conservative group. Patients with coxarthrosis stage I and II, besides higher efficiency had prolonged period of remission, while patients with coxarthrosis stage III returned to the near-baseline level of pain only in 3-6 months. Conclusions: RFD is an effective treatment modality for patients with initial coxarthrosis stages, which helps to reduce significantly the disability period compared with conservative therapy. RFD is the only method of effective hip pain relieve in patients with severe comorbidities allowing to reduce analgesic consumption. This method is minimally invasive, has low cost, permits repeated procedures, making it attractive for both physicians and patients.
Introduction. Clinical efficacy of radiofrequency destruction (RFD) for the treatment of vertebrogenic pain syndrome and pain in coxarthrosis is confirmed by multiple studies. However the matter on morphologic changes in the nerve and surrounding tissue after directed local radiofrequency effect. Materials and methods. The study was performed on autopsy material – fragments of tibial nerve from 6 patients with lethal outcomes. Radiofrequency destruction was performed according to a standard protocol: within 90 sec under 80 C°. The sections were stained with hematoxylin and eosin by Bilshowski-Gros method. Results. It was shown that RFD causes the coagulation lesions of the nerve tissue such as spiral deformation, axon fragmentation and nerve fibers dissociation. Conclusion. The data obtained may serve as a morphologic basis of RDF clinical efficacy. The presence of undamaged Schwann cells allows assuming the tropism of the effect upon the nerve tissue.
Fifteen patients with lumbar osteochondrosis complicated by L4-L5 and L5-S1 disk protrusion treated by interosseous laser diskectomy are reviewed. Early and long-term results are given. In 14 patients (93%) good results were achieved, 1 patients (7%) had satisfactory outcome. Indications for intercutaneous laser diskectomy are the following: low back pain irradiating to lower extremity, and persistent over 3 months, failed conservative treatment, absence of neurologic complications, such as paresis, disturbance of pelvic organs function as well as disk protrusion (size up to 6 mm) confirmed by CT, MRI. This method does not damage soft tissues and allows to achieve persistent release of pain syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
