Traumatic hip joint tamponade. Two cases with femoral head ischaemia.
Two elderly patients had pain after hip trauma with no radiographic evidence of fracture. Computed tomography demonstrated capsular haematoma. Scintimetry revealed femoral head ischaemia. Intracapsular hip joint pressure in extension was 240 and 176 mm Hg, respectively, in neutral position and 280 and 360 mm Hg in internal rotation. The hip joints were aspirated for 8 ml and 5 ml of blood, respectively, leading to pain relief and regained radiotracer uptake in the femoral head. It is concluded that traumatic hip joint tamponade may cause femoral head ischaemia which may be reversed by aspiration.
