The Grice procedure. Extra-articular subtalar arthrodesis.

The Grice procedure is an extra-articular arthrodesis of the subtalar joint performed through a lateral approach using a corticocancellous bone graft. It is useful in multiple hindfoot deformities, especially in the growing child, in whom its use allows for full growth of the hindfoot and restoration of the original height of the collapsed hind-foot. When performed well and for proper indications, the procedure is relatively successful, with high fusion rates, high reported success rates, and little need for triple arthrodesis on long-term follow-up. Complications can occur, however, and these are best avoided by careful preoperative planning and evaluation.
