The system provides cementless and cemented variants. Prevision hip stems are modular with a short proximal and longer distal component, or monobloc hip stems. Modular components are coupled via a Prevision specific conical connection with a torque wrench and a tension nut to apply a predefined torsional moment on the connection. The distal component of modular Prevision stems can be combined with locking screws for additional bone fixation.\n\nBoth types, the monobloc and the modular, provide a 12\u002F14 taper that serves as a connection for metal or ceramic prosthesis heads. Prevision hip stems are combined at the acetabulum with a cementless or cemented acetabular cup.",[14],{"name":15,"affiliation":16,"role":17},"Henning Windhagen, Prof. Dr.","Orthopädische Kliniken im Annastift, MHH","PRINCIPAL_INVESTIGATOR",[19,25],{"name":20,"role":21,"phone":22,"phoneExt":23,"email":24},"Kerstin Bergmann","CONTACT","+49746195-","0","studies@aesculap.de",{"name":26,"role":21,"phone":22,"phoneExt":23,"email":24},"Lutz Dreyer, Dr.",[28,43],{"facility":29,"status":30,"city":31,"state":7,"zip":32,"country":33,"countryCode":34,"cosmosGeoPoint":35,"geoPoint":40,"contacts":41},"Orthopädische Kliniken im Annastift, MHH, Anna-von-Borries-Str. 1-7","RECRUITING","Hanover","30625","Germany","DE",{"type":36,"coordinates":37},"Point",[38,39],9.73322,52.37052,{"lat":39,"lon":38},[42],{"name":15,"role":21,"phone":7,"phoneExt":7,"email":7},{"facility":44,"status":30,"city":45,"state":46,"zip":47,"country":48,"countryCode":49,"cosmosGeoPoint":50,"geoPoint":54,"contacts":55},"Hinchingbrooke Hospital","Huntingdon","Cambridgeshire","PE29 6NT","United Kingdom","UK",{"type":36,"coordinates":51},[52,53],-0.18651,52.33049,{"lat":53,"lon":52},[56,60],{"name":57,"role":21,"phone":58,"phoneExt":7,"email":59},"Vijay Killampalli","+44 1480-8799","vijay.killampalli@nhs.net",{"name":57,"role":17,"phone":7,"phoneExt":7,"email":7},{"type":62,"investigatorFullName":7,"investigatorTitle":7,"investigatorAffiliation":7,"oldNameTitle":7,"oldOrganization":7},"SPONSOR","100564231","prospective-follow-up-of-the-prevision-hip-stem-with-comparison-of-different-implant-variants-100564231",false,"NCT06626490","Prospective Follow-up of the Prevision Hip Stem With Comparison of Different Implant Variants","PREMO","Inclusion Criteria:\n\n* Revision hip arthroplasty patients treated with a Prevision hip stem\n* Written patient informed consent\n* Patients are able to attend at follow-up examinations\n\nExclusion Criteria:\n\n* Patients \\\u003C 18 years at surgery\n* Pregnancy at implantation\n* Patients held in a custodial setting\n* Patients in a relationship of dependence on the sponsor, the clinic or the investigator","ALL","18 Years",{"count":73,"type":74},120,"ESTIMATED","OBSERVATIONAL","The study design is confirmative for non-inferiority of the functional outcome of the implants and is intended to examine the safety and performance of the Prevision hip stem.
