The Grice extra-articular subtalar arthrodesis in the treatment of spastic hindfoot valgus deformity.

The results of the Grice extra-articular subtalar arthrodesis were evaluated in 102 feet of 60 ambulatory patients with spasticity at an average of five years postoperatively. Results were satisfactory in 96 feet (94 per cent). Unsatisfactory results were attributed to recurrent deformity in four feet and over-correction in two. No other significant complications were identified. The Grice arthrodesis is recommended for hindfoot valgus deformity secondary to spasticity which is refractory to non-operative management.
