The lumbar facet joints have been implicated as one of the causes of low-back pain syndromes. About 15-40% of patients who presented with chronic low-back pain was attributed to lumbar facet joint pain. The purpose of this study was to analyse whether radiofrequency denervation is better than SHAM procedure in treating chronic low-back pain caused by lumbar zygapophysial joints pathology. From the four identified randomised control trials, there is conflicting evidence at an intermediate 3-6-month stage, however; one study demonstrates statistical significance of radiofrequency denervation at 3 months. Longer-term follow-up is needed to prove the efficacy of radiofrequency denervation technique.
IntroductionGiant or solitary osteochondroma is part of a rare disorder known as synovial osteochondromatosis. It forms part of a spectrum of disease characterized by metaplastic changes within the joint synovium that are eventually extruded as loose bodies. It has been suggested that solitary synovial osteochondroma forms as progression of synovial osteochondromatosis through a process of either coalescence of multiple smaller bodies or the growth of a dominant synovial osteochondroma. Previous studies have shown that it occurs as a late phase of the disease. We report a rare case of giant synovial osteochondromatosis at the elbow causing ulnar nerve neuropathy and mechanical symptoms which has not been previously reported in the literature.Case reportWe report a case of a 56 year old Western European gentleman who presented with ulnar nerve neuropathy and swelling behind the elbow. The patient underwent MR imaging and subsequent biopsy that demonstrated synovial osteochondromatosis. Initially the patient declined surgery and opted for a watch and wait approach. Five years later he returned with worsening symptoms and underwent successful surgical resection of a giant solitary synovial osteochondroma.ConclusionThe unique outcome in our patient despite the long interval between presentation and surgical treatment resulted in early full resolution of symptoms within a short period. It may suggest an improved prognosis as compared to multiple synovial osteochondromatosis in terms of mechanical and neurological outcomes.
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.
