this potentially very unstable injury it would be wise to reduce this dislocation and hold it temporarily with percutaneous Kirschner wires. This should be done as early as possible before oedema makes it too difficult. As always, a compromise must then be sought between adequate immobilization to allow soft tissue healing and early mobilization to prevent stiffness. A period of 4 weeks’ immobilization proved sufficient in this case and would seem reasonable.

Cullen’s sign: a new association with central dislocation of the hip joint

R. D. Sayers and K. M. Porter

Birmingham Accident Hospital

INTRODUCTION PERIUMBILICAL discoloration caused by haemorrhage is known eponymously as Cullen’s sign and was initially reported in association with ruptured ectopic preg- nancy (Cullen, 1918), and subsequently in association with acute pancreatitis (Fallis, 1937). A similar discolora- tion in the flanks has been described in acute pancreatitis (Turner, 1920) and is known as Grey Turner’s sign.

Cullen’s sign has also been reported in a few other conditions including hepatocellular carcinoma (Mabin and Gelfand, 1974), and after percutaneous liver biopsy (Capron et al., 1977).

Cullen’s sign has not previously been reported in association with musculoskeletal injury.

We report a new association of Cullen’s sign with central dislocation of the hip joint.

CASE REPORT Following a fall a 79-year-old man complained of pain in his left hip region and an inability to bear weight. He was clinically shocked and required resuscitation with intravenous plasma expanders and blood. Radiographs revealed a central dislocation of his left hip joint (Fig. 1). He was treated initially with skin traction.

Two days after admission he developed left iliac fossa pain and vomiting. Examination revealed a pulse rate of 90/min (atrial fibrillation) and a blood pressure of 130/90 mmHg. He was afebrile. There was extensive bruising over his left hip joint and periumbilical bruising (Cullen’s sign) (Fig. 2). His left iliac fossa was tender without guarding and his bowel sounds were quiet. A rectal examination was normal. Chest and abdominal radiographs were normal.

Investigations revealed a haemoglobin of 12.1 g/d1 and a white cell count of 8.0~10”/1. The serum urea, electrolytes and amylase were normal. Examination of the urine was

normal. His abdominal pain settled on a conservative regi- men of restricted oral fluids, and his bruising resolved.

The central dislocation of the hip joint was reduced satis- factorily under general anaesthetic and a Denham pin was inserted through the femoral condyles to allow skeletal trac- tion. He remained on traction for 6 weeks and was then mobilized non-weight-bearing for a further 6 weeks.

DISCUSSION The most likely cause of this patient’s umbilical bruis- ing was blood from a retroperitoneal haematoma secondary to his pelvic fracture, tracking through the tissue planes of his abdominal wall to reach the umbili- cus.

Retroperitoneal haematoma is a common complica- tion of pelvic fractures because of the associated soft
