Three elderly patients with incapacitating back and leg pain were found to have spontaneous osteoporotic fractures of the sacrum. The clinical picture in these three patients suggests a distinct clinical entity of spontaneous osteoporotic fracture of the sacrum (SOFS). This is characterized by severe low back, hip, and leg pain that suggests initially lumbosacral radicular compression, either from disk disease, spinal stenosis, tumor. However, objective mechanical signs more typical of those entities may be absent or minimal in SOFS. Symptoms suggestive of a cauda equina syndrome may be present, but there is minimal or no neurological deficit on examination. Marked sacral tenderness is a hallmark of SOFS.
三名患有严重腰腿痛的老年患者被发现患有自发性骶骨骨质疏松性骨折。这三名患者的临床表现提示了一种独特的临床实体——自发性骶骨骨质疏松性骨折（SOFS）。其特征为严重的下背部、臀部和腿部疼痛，最初提示为腰骶部神经根受压，原因可能是椎间盘疾病、椎管狭窄或肿瘤。然而，在SOFS中，这些疾病更典型的客观体征可能不存在或很轻微。可能存在马尾综合征的症状，但检查时神经功能缺损轻微或没有。明显的骶骨压痛是SOFS的一个标志。
