However, secondary displacement after surgery sometimes occurs in elderly patients with a metaphyseal comminution and\/or cases in which the subchondral support pegs were not placed immediately below the subchondral zone.<\/jats:p><jats:p>We treated elderly patients suffering from distal radius fractures with metaphyseal comminution, using both volar fixed angle plate with or without augmentation with a hydroxyapatite bone graft substitute to investigate the benefit of augmentation for maintaining a fracture reduction. We evaluated the differences among radiographic parameters including palmar tilt, radial inclination, and ulnar variance on immediate postoperative and final follow-up radiographs to analyse the maintenance of the initial reduction.<\/jats:p><jats:p>There were no significant differences between the two groups in terms of palmar tilt (P = 0.80) and radial inclination (P = 0.17); however, ulnar variance increased significantly in the group treated with a volar fixed angle plate without augmentation (P &lt; 0.05).<\/jats:p><jats:p>It might be useful to use a combination technique of a locking plate system and the hydroxyapatite bone graft substitute as augmentation to treat distal radius comminuted fractures in elderly patients.<\/jats:p>","DOI":"10.1142\/s0218810411005023","type":"journal-article","created":{"date-parts":[[2011,2,22]],"date-time":"2011-02-22T10:25:23Z","timestamp":1298370323000},"page":"29-37","source":"Crossref","is-referenced-by-count":15,"title":["USE OF THE VOLAR FIXED ANGLE PLATE FOR COMMINUTED DISTAL RADIUS FRACTURES AND AUGMENTATION WITH A HYDROXYAPATITE BONE GRAFT SUBSTITUTE"],"prefix":"10.1142","volume":"16","author":[{"given":"Akira","family":"Goto","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine, Osaka 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyoshi","family":"Murase","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine, Osaka 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunihiro","family":"Oka","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine, Osaka 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideki","family":"Yoshikawa","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine, Osaka 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"crossref","first-page":"1021","DOI":"10.1016\/S0363-5023(05)80153-4","volume":"20","author":"Gesensway D.","journal-title":"J.
