Distal radius fractures account for one in five bony injuries in both primary and secondary care. These are commonly the result of a fall on outstretched hands or high-energy trauma. On assessment, clinicians should determine the mechanism of injury, associated bony or soft tissue injuries, and neurovascular symptoms. Investigations should always include radiographs to evaluate for intra-articular involvement and fracture displacement. Owing to the heterogeneous injury patterns and patient profiles, the preferred management should consider the severity of the fracture, desired functional outcome and patient comorbidities. Non-operative management in select patients can give good results, especially in older adults. Immobilisation with or without reduction forms the mainstay of non-operative treatment. Surgical management options include closed reduction and application of a cast, percutaneous K-wires, open reduction and internal fixation with plates, or external fixation. Patients should be encouraged to mobilise as soon as it is safe to do so, to prevent stiffness. Median nerve compression is the most common complication followed by tendon rupture, arthrosis and malunion. This article outlines the British Orthopaedic Association Standards for Trauma and Orthopaedics for the management of distal radius fractures.
An 80-year-old female patient presented with a 3-month history of firm swellings in the left groin, right hip and left shoulder. Apart from a previous history of breast cancer, treated several years prior with chemoradiotherapy and hormone treatment, she was otherwise fit and healthy.
Objective: To determine the differential diagnosis of bone lesions causing hip pain in children and the association between radiographic features of aggression and MRI appearances with final diagnosis. Methods: Retrospective review of children with hip pain referred to a specialist musculoskeletal oncology service between September 2018 and December 2020. Patient demographics, lesion location, the radiographic and MRI features, and the final diagnosis, which was made either by image-guided biopsy, surgical curettage or based on typical imaging features were recorded. Statistical analysis examined the association between the Lodwick-Madewell score (determined from available radiographs) and MRI findings with final diagnosis. Results: Fifty-nine patients were included, 40 males and 19 females with mean age 10.9 years, (range 3–16 years). Final diagnoses were based on histology in 24 (40.7%) cases and imaging in 35 (59.3%) cases. Eighteen lesions (30.5%) were classed as non-neoplastic, 31 (52.5%) as benign and 10 (16.9%) as malignant, of which four were primary bone sarcomas. There was a significant association between the Lodwick-Madewell score and final diagnosis (p < 0.001). On MRI, bone marrow oedema, presence of a focal lesion, bone expansion and the presence of an extraosseous mass were all significantly associated with final diagnostic classification. Conclusion: The differential diagnosis of hip pain in children presenting to a bone tumour service is wide. Most cases are due to benign or non-neoplastic conditions, with only 10 out of 59 children having a malignant lesion. Radiography complemented by MRI plays a major role in differentiating non-neoplastic, benign neoplastic and malignant lesions and in determining the requirement for needle biopsy. Advances in knowledge: This is the first study to consider how imaging features relate to diagnosis in suspected paediatric hip tumours. Use of this information can help in determining which cases should undergo needle biopsy.
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.
