It can interfere with the ability to run and even walk without pain. An implant of cobalt-chrome steel alloy to replace the base of the proximal phalanx is one solution. The purpose of this study is to review our results with one of these implants. Materials and Methods: A series of 23 cases of hemiarthroplasty for the treatment of hallux rigidus from June 2000 to October 2001 has been evaluated using the AOFAS rating system, and the results are presented. Results: The average preoperative AOFAS score was 57 (range, 39 to 80). The AOFAS score after hemiarthroplasty was 88 (range, 75 to 100) at last followup (34 to 72 months). There were no perioperative complications except for a small hematoma. Only one patient has required further surgery after 3 years for worsening of a preexisting tendency to hallux valgus. Conclusion: A hemiarthroplasty retained, in most cases, joint mobility, strength, and alignment while relieving pain. There was no evidence, at last followup, of component loosening or osteolysis. <\/jats:p>","DOI":"10.3113\/fai.2008.0273","type":"journal-article","created":{"date-parts":[[2008,3,18]],"date-time":"2008-03-18T22:43:23Z","timestamp":1205880203000},"page":"273-281","source":"Crossref","is-referenced-by-count":52,"title":["Hemiarthroplasty in the Treatment of Hallux Rigidus"],"prefix":"10.1177","volume":"29","author":[{"given":"Charles","family":"Sorbie","sequence":"first","affiliation":[{"name":"Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerald Anthony Briden","family":"Saunders","sequence":"additional","affiliation":[{"name":"Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2008,3,1]]},"reference":[{"key":"bibr1-FAI.2008.0273","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199904083401419"},{"key":"bibr2-FAI.2008.0273","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800407"},{"key":"bibr3-FAI.2008.0273","doi-asserted-by":"publisher","DOI":"10.1097\/01.btf.0000235417.46038.2b"},{"key":"bibr4-FAI.2008.0273","doi-asserted-by":"publisher","DOI":"10.1016\/S1067-2516(98)80004-5"},{"key":"bibr5-FAI.2008.0273","doi-asserted-by":"publisher","DOI":"10.1016\/S1083-7515(01)00004-3"},{"key":"bibr6-FAI.2008.0273","doi-asserted-by":"crossref","first-page":"423","DOI":"10.1016\/S0891-8422(23)00816-9","volume":"13","author":"Camasta CA","year":"1996","journal-title":"Clin.
