The shoulder, specifically the glenohumeral joint, by virtue of its anatomical characteristics and biomechanics confers a large range of movement, which ultimately results in a joint that is inherently prone to becoming unstable. The incidence of acute traumatic shoulder dislocation varies within the sporting environment, commonly occurring following direct trauma. Anterior dislocations account for nearly 90% of all dislocations. While most are referred and managed in the emergency department, pitch-side relocation by experienced clinicians does occur prior to referral. The aim of this study was to delineate a guideline specifically for the pitch-side management of this common injury. A literature search of PubMed and Medline using the keywords ‘prehospital’, ‘pitch-side’, ‘shoulder dislocation’ and ‘reduction’ or ‘relocation technique’ was performed, and the available literature was reviewed and collated. Articles focusing on reduction techniques were then reviewed, with particular consideration on their applicability to a pitch-side setting. While studies exist that compare and contrast examination and reduction techniques, most are based in a hospital setting. To date, there is no standardised management protocol published for the initial management of an anterior dislocated shoulder in a pitch-side setting. This article addresses this discrepancy and proposes a structured, algorithmic approach to the pitch-side management of a shoulder dislocation. The article addresses factors to consider in a pitch-side setting, suitable techniques and postreduction care. While a systematic approach has been delineated in this article, we recommend those pitch-side medical practitioners who provide this form of support should have attended appropriate training and ensure adequate malpractice cover.
A 70-year-old woman presented with right knee pain and a 'grinding' sensation 6 months after a total knee replacement for osteoarthritis. Clinical examination revealed a valgus deformity, patellofemoral crepitus and a reduced knee flexion. Radiographs revealed distinctive findings including the 'bubble sign', 'cloud sign' and the 'metal line sign', which are diagnostic of metallosis. Metallosis is an uncommon complication of total joint replacements, where bone and periprosthetic soft tissues are infiltrated by metallic debris from wearing of the prostheses. This usually occurs in high-wear joints such as hips and knees. Treatment for patients diagnosed with metallosis is synovectomy and a revision surgery. Our patient underwent revision surgery 5 years after her initial surgery.
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.
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.
