Abstract:
Myositis ossificans is a rare, benign, solitary and self-limited disease, characterized by non-neoplastic ectopic bones in soft tissue or skeletal muscle, most commonly in humerus, quadriceps femoris and adductor muscle group, with or without a history of external injuries. The main manifestations of this disease are local pain and swelling, loss of range of motion, and X-ray examination is one of the important means to diagnose myositis ossificans. Most patients can be treated conservatively with good results. For persistent symptoms or progressive cases, surgical resection can also be selected. In this paper, a progressive child case is introduced, and the clinical features, X-ray manifestations and treatment methods of the patient are discussed in order to improve the reference for the diagnosis and treatment of myositis ossificans.
骨化性肌炎是一种少见的、良性的、单发的、自限性的病变,其特点是在软组织或骨骼肌中出现非肿瘤性的异位骨,最常见于肱骨、股四头肌和内收肌群,病变在有或没有外伤史的情况下均可呈现。该疾病主要表现为局部疼痛和肿胀,运动范围丧失,X 线检查是诊断骨化性肌炎的重要手段之一。大多数患者可以实施保守治疗且效果很好,对于持续的症状或进展性病例,也可以选择手术切除。本文引入一例进展性的儿童病例,对患者临床特征、X 线表现和治疗方式进行论述,以期为骨化性肌炎的诊疗提高参考。
