Lateral talocalcaneal angle in assessment of subtalar valgus: follow-up of seventy Grice-Green arthrodeses

Abstract

To determine whether definitive radiographic criteria could be elucidated for the Grice-Green extra-articular subtalar arthrodesis, all 70 cases performed at the Shriner's Hospital for Crippled Children, Erie, Pennsylvania, from 1972 to 1980 were reviewed. Patients were followed both clinically and radiographically an average of 4 years and 11 months. Major conclusions were as follows: 1) the standing lateral talocalcaneal angle is the most reliable measurement for operative selection and assessment of postoperative success; and 2) by using strict operative techniques and proper patient selection, a 90% success rate can be expected.
