Khác với những kết quả từ chấn thương và viêm khớp, rối loạn xương đòn là không phổ biến. Một số rối loạn nontraumatic chỉ được tìm thấy ở trẻ sơ sinh và trẻ em, chẳng hạn như sinh gãy xương, hyperostosis vỏ não trẻ con, pseudarthrosis bẩm sinh, loạn sản cleidocranial, | Nontraumatic Disorders of the Clavicle Rodney K. Beals MD Donald D. Sauser MD Abstract Other than those resulting from trauma and arthritis disorders of the clavicle are uncommon. Some nontraumatic disorders are found only in infancy and childhood such as birth fracture infantile cortical hyperostosis congenital pseudarthrosis cleidocranial dysplasia and short clavicle syndrome. Other nontraumatic disorders occur in both children and adults these include anterior subluxation of the sternoclavicular joint Friedrich s disease hypertrophic osteitis chronic multifocal periosteitis and arthropathy and osteomyelitis. Some nontraumatic clavicular disorders are found only in adults such as distal osteolysis. Because the description and nomenclature of these disorders arise from several medical disciplines they often are confusing. Until clear distinguishing features are described it is advisable to combine some of the entities. This is especially true of the nonsuppurative inflammatory disorders of the clavicle which appear to fall under the heading of spondyloarthropathy. Treatment varies by disorder and may include symptomatic and expectant management drug therapy and nonsurgical or surgical treatment.
