A method based on the analysis of the impact force applied during the press-fit insertion of the AC implant using a hammer instrumented with a force sensor was developed to assess the AC implant stability. The aim of the present study was to investigate the performance of a method using a hammer equipped with strain sensors to retrieve the AC implant stability. Different AC implants were inserted in five bovine samples with different stability conditions leading to 57 configurations. The AC implant was impacted 16 times by the two hammers consecutively. For each impact; an indicator IS (respectively IF) determined by analyzing the time variation of the signal corresponding to the averaged strain (respectively force) obtained with the stress (respectively strain) hammer was calculated. The pull-out force F was measured for each configuration. F was significantly correlated with IS (R2 = 0.79) and IF (R2 = 0.80). The present method has the advantage of not modifying the shape of the hammer that can be sterilized easily. This study opens new paths towards the development of a decision support system to assess the AC implant stability.<\/jats:p>","DOI":"10.3390\/s18010062","type":"journal-article","created":{"date-parts":[[2017,12,27]],"date-time":"2017-12-27T11:16:00Z","timestamp":1514373360000},"page":"62","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Ex Vivo Evaluation of Cementless Acetabular Cup Stability Using Impact Analyses with a Hammer Instrumented with Strain Sensors"],"prefix":"10.3390","volume":"18","author":[{"given":"Antoine","family":"Tijou","sequence":"first","affiliation":[{"name":"Laboratoire de Mod\u00e9lisation et de Simulation Multi-Echelle, CNRS, UMR CNRS 8208, 61 Avenue du G\u00e9n\u00e9ral de Gaulle, 94010 Cr\u00e9teil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Rosi","sequence":"additional","affiliation":[{"name":"Laboratoire de Mod\u00e9lisation et de Simulation Multi-Echelle, UMR CNRS 8208, Universit\u00e9 Paris-Est, 61 Avenue du G\u00e9n\u00e9ral de Gaulle, 94010 Cr\u00e9teil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Hernigou","sequence":"additional","affiliation":[{"name":"Service de Chirurgie Orthop\u00e9dique et Traumatologique, H\u00f4pital Henri Mondor AP-HP, CHU Paris 12, Universit\u00e9 Paris-Est, 51 Avenue du Mar\u00e9chal de Lattre de Tassigny, 94010 Cr\u00e9teil, France"},{"name":"\u00c9quipe 10, Groupe 5, IMRB U955, INSERM\/UPEC, 51 Avenue du Mar\u00e9chal de Lattre de Tassigny, 94010 Cr\u00e9teil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles-Henri","family":"Flouzat-Lachaniette","sequence":"additional","affiliation":[{"name":"Service de Chirurgie Orthop\u00e9dique et Traumatologique, H\u00f4pital Henri Mondor AP-HP, CHU Paris 12, Universit\u00e9 Paris-Est, 51 Avenue du Mar\u00e9chal de Lattre de Tassigny, 94010 Cr\u00e9teil, France"},{"name":"\u00c9quipe 10, Groupe 5, IMRB U955, INSERM\/UPEC, 51 Avenue du Mar\u00e9chal de Lattre de Tassigny, 94010 Cr\u00e9teil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillaume","family":"Ha\u00efat","sequence":"additional","affiliation":[{"name":"Laboratoire de Mod\u00e9lisation et de Simulation Multi-Echelle, CNRS, UMR CNRS 8208, 61 Avenue du G\u00e9n\u00e9ral de Gaulle, 94010 Cr\u00e9teil, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,12,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"295","DOI":"10.1016\/0883-5403(92)90052-R","article-title":"Stability of press-fit acetabular cups","volume":"7","author":"Adler","year":"1992","journal-title":"J.
