Myositis ossificans (MO) is a disorder characterized by the intramuscular proliferation of fibroblasts and osteoblasts, with subsequent deposition of bone and cartilage. A typical clinical presentation involves traumatic injury to a young adult, usually localized to the thigh, buttock, or upper arm, with resultant MO and mildly restricted range of motion in adjacent joints. Rarely, MO is associated with peripheral neuropathies involving the radial, median, sciatic, and sural nerves. The authors present an unusual case of MO causing a brachial plexopathy. To their knowledge, this is the first description of such a presentation.
骨化性肌炎（MO）是一种以成纤维细胞和成骨细胞在肌肉内增殖，随后形成骨和软骨沉积为特征的疾病。典型的临床表现为年轻成年人受到创伤性损伤，通常局限于大腿、臀部或上臂，继而发生骨化性肌炎，并导致相邻关节活动范围轻度受限。骨化性肌炎很少与累及桡神经、正中神经、坐骨神经和腓肠神经的周围神经病变相关。作者报告了一例罕见的骨化性肌炎导致臂丛神经病变的病例。据他们所知，这是对此类表现的首次描述。
