An 81-year-old woman had severe hip pain after a fall. Radiography was normal, but computed tomography and sonography showed a minor, displaced acetabular fracture and hemarthrosis. Aspiration of 15 ml of blood reduced the intracapsular pressure in the neutral position from 30 kPa to atmospheric pressure with relief of pain and increased joint motion. This case confirms that acetabular fracture may escape radiographic diagnosis and cause hip joint tamponade. Aspiration should be considered as a palliative and possibly therapeutic measure.
一名81岁女性跌倒后出现严重髋部疼痛。X线摄影结果正常，但计算机断层扫描和超声检查显示有轻微的髋臼骨折伴移位及关节积血。抽出15毫升血液后，中立位时关节囊内压力从30千帕降至大气压，疼痛缓解，关节活动度增加。该病例证实髋臼骨折可能无法通过X线摄影诊断出来，并可导致髋关节填塞。抽吸应被视为一种姑息性且可能具有治疗作用的措施。
