Survival of the prosthesis was assessed from the radiographs of 37 patients after a mean follow-up of 50\u00a0months (12 to 107). The functional results of 31 patients were assessed using range-of-movement, Mayo elbow performance score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH) score and the RAND 36-item health survey.<\/jats:p><jats:p>At the most recent follow-up 25 prostheses were still well fixed, nine had been removed because of loosening, and three remained implanted but were loose. The mean time from implantation to loosening was 11 months (2 to 24). Radiolucent lines that developed around the prosthesis before removal were mild in three patients, moderate in one and severe in five. Range of movement parameters and mass grip strength were significantly lower in the affected elbow than in the unaffected side. The mean MEPS score was 86 (40 to 100) and the mean DASH score was 23 (0 to 81). According to RAND-36 scores, patients had more pain and lower physical function scores than normal population values.<\/jats:p><jats:p>Loosening of press-fit radial head prostheses is common, occurs early, often leads to severe osteolysis of the proximal radius, and commonly requires removal of the prosthesis.<\/jats:p>","DOI":"10.1302\/0301-620x.94b6.28176","type":"journal-article","created":{"date-parts":[[2012,5,24]],"date-time":"2012-05-24T15:25:59Z","timestamp":1337873159000},"page":"805-810","source":"Crossref","is-referenced-by-count":105,"title":["Short- to mid-term results of metallic press-fit radial head arthroplasty in unstable injuries of the elbow"],"prefix":"10.1302","volume":"94-B","author":[{"given":"T.","family":"Flinkkil\u00e4","sequence":"first","affiliation":[{"name":"Oulu University Hospital, Department of Surgery, Division of Orthopaedic and Trauma Surgery, PL21, FIN-90029 OYS, Oulu, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Kaisto","sequence":"additional","affiliation":[{"name":"Oulu University Hospital, Department of Surgery, Division of Orthopaedic and Trauma Surgery, PL21, FIN-90029 OYS, Oulu, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Sirni\u00f6","sequence":"additional","affiliation":[{"name":"Oulu University Hospital, Department of Surgery, Division of Orthopaedic and Trauma Surgery, PL21, FIN-90029 OYS, Oulu, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Hyv\u00f6nen","sequence":"additional","affiliation":[{"name":"Oulu University Hospital, Department of Surgery, Division of Orthopaedic and Trauma Surgery, PL21, FIN-90029 OYS, Oulu, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Leppilahti","sequence":"additional","affiliation":[{"name":"Oulu University Hospital, Department of Surgery, Division of Orthopaedic and Trauma Surgery, PL21, FIN-90029 OYS, Oulu, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"42","reference":[{"key":"r1","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1097\/00003086-199104000-00021","volume":"265","author":"Morrey BF","year":"1991","journal-title":"Clin Orthop Relat Res"},{"key":"r2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200408000-00018"},{"key":"r3","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199911000-00014"},{"key":"r4","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200108000-00010"},{"key":"r5","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-200101000-00009"},{"key":"r6","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200402000-00009"},{"key":"r7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2008.12.024"},{"key":"r8","doi-asserted-by":"publisher","DOI":"10.1054\/arth.2001.16499"},{"key":"r9","doi-asserted-by":"publisher","DOI":"10.1002\/ca.10256"},{"key":"r10","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2008.04.011"},{"key":"r11","first-page":"2469","volume":"89","author":"Popovic N","year":"2007","journal-title":"J Bone Joint Surg [Am]"},{"key":"r12","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.18004217203"},{"key":"r13","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200903000-00003"},{"key":"r14","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.88B1.16704"},{"key":"r15","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200905000-00007"},{"key":"r16","first-page":"2192","volume":"88","author":"Grewal R","year":"2006","journal-title":"J Bone Joint Surg [Am]"},{"key":"r17","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198668050-00005"},{"key":"r18","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0274(199606)29:6<602::AID-AJIM4>3.0.CO;2-L"},{"key":"r19","doi-asserted-by":"crossref","unstructured":"Morrey BF, An KN.Functional evaluation of the elbow.
