immobilization in supination vs. pronation. Sarmiento A. Zagorski JB. Sinclair WF. Clinical Orthopaedics & Related Research. (146):175-83, 1980 Jan-Feb. In a prospective study, 156 Colles' fractures were treated with a functional Orthoplast brace. Approximately one-half were braced in pronation and one-half in supination. One hundred and four were available for follow-up. Results were analyzed by type of fracture and position of immobilization (pronation versus supination). In evaluating the results, we found that: (1) displaced Colles' fractures without articular involvement (Type II) braced in supination yielded superior anatomic results when compared with those treated in pronation; (2) Type IV (displaced intra-articular) fractures braced in supination obtained a significantly higher percentage of excellent functional and anatomic results than those braced in pronation. In general, treatment with functional bracing yielded 90% excellent or good functional results.
