Their mean age was 61 years (46 to 69). The mean follow-up was 32 months (19 to 50). Before clinical use, the strength retention and hydrolytic in vitro degradation properties of the implants were studied in the laboratory over a two-year period. A successful clinical outcome was determined by the radiological findings and the Harris hip score. <\/jats:p><jats:p> All the patients had a satisfactory outcome and no mechanical failures or other complications were observed. No protrusion of any of the impacted grafts was observed beyond the mesh. According to our preliminary laboratory and clinical results the biodegradable mesh is suitable for augmenting uncontained acetabular defects in which the primary stability of the implanted acetabular component is provided by the host bone. In the case of defects of the acetabular floor this new application provides a safe method of preventing graft material from protruding excessively into the pelvis and the mesh seems to tolerate bone-impaction grafting in selected patients with primary and revision total hip replacement. <\/jats:p>","DOI":"10.1302\/0301-620x.92b1.22846","type":"journal-article","created":{"date-parts":[[2010,1,1]],"date-time":"2010-01-01T00:22:43Z","timestamp":1262305363000},"page":"179-185","source":"Crossref","is-referenced-by-count":3,"title":["The use of a biodegradable mesh plate to augment grafting of an acetabular defect"],"prefix":"10.1302","volume":"92-B","author":[{"given":"P.","family":"V\u00e4\u00e4n\u00e4nen","sequence":"first","affiliation":[{"name":"Department of Physics University of Kuopio, POB 1627, FI-70211, Kuopio, Finland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Pajam\u00e4ki","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Paakkala","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hatanp\u00e4\u00e4 Hospital, Hatanp\u00e4\u00e4nkatu 24, FI-33521, Tampere, Finland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
