Abstract
We assessed the functional outcome of fractures of the os calcis a minimum of twenty- four months following injury.
Eighty-three patients with 85 fractures were assessed a minimum of two years following fracture of the os calcis, using a validated functional outcome measure designed specifically for fractures of the os calcis, and an EQ5D. Radiographic analysis of all fractures was performed to attempt to correlate outcome scores with the fracture pattern.
Sixty per cent of the questionnaires were returned completed. Forty percent of the fractures were treated surgically, the remainder with a period of weight relief, followed by physiotherapy and graded weight-bearing. The majority of patients reported a mild hind foot pain (8/10 on a VAS), and all reported some difficulties with walking on uneven terrain. There was no appreciable difference in the outcomes comparing patients treated by open reduction and internal fixation and those treated non-operatively.
This study demonstrates a surprisingly high patient satisfaction rate following fractures of the os calcis whether they are treated operatively or non-operatively. Patients seemed to have compensated for any altered function very well. We were not able to identify specific fracture patterns that were associated with poorer outcomes.
