[Mechanical testing of implant properties of thoracoscopic implantation of ventral spinal stabilizing systems. Comparative study with the ISO/DIS 12189-2 corpectomy model and an improved synthetic model]T M Grupp
Aesculap AG and Co KG, Forschung und Entwicklung, Am Aesculap Platz, 78532 Tuttlingen
Orthopade 31:406-12. 2002..The corpectomy model according to Kotani et al. offers an interesting alternative to the ISO/DIS 12189-2 test method for asymmetrically designed and antero-laterally positioned spinal implants due to the unconstrained ball joint...
Biotribological evaluation of artificial disc arthroplasty devices: influence of loading and kinematic patterns during in vitro wear simulationThomas M Grupp
Aesculap AG Research and Development, Tuttlingen, Germany
Eur Spine J 18:98-108. 2009..Based on our findings it seems to be more reliable to predict the clinical wear behavior of an artificial disc replacement using the ISO/FDIS 18192-1 method...
Fixed and mobile bearing total knee arthroplasty--influence on wear generation, corresponding wear areas, knee kinematics and particle compositionT M Grupp
Aesculap AG Research and Development, Am Aesculap Platz, D 78532 Tuttlingen, Germany
Clin Biomech (Bristol, Avon) 24:210-7. 2009..The objective of our study was to investigate a fixed and mobile bearing knee design with identical femoral articulation in regard to wear, tibio-femoral kinematics and particle size distribution...
Fixed bearing knee congruency -- influence on contact mechanics, abrasive wear and kinematicsThomas M Grupp
Aesculap AG Research and Development, Tuttlingen and Ludwig Maximilian University Clinic for Orthopedic Surgery, Grosshadern Medical Center, Munich, Germany
Int J Artif Organs 32:213-23. 2009..our observations demonstrate that increased congruency in conjunction with decreased surface contact stresses significantly contributes to reducing wear in fixed bearing knee articulations...
Alternative bearing materials for intervertebral disc arthroplastyThomas M Grupp
Aesculap AG Research and Development, Tuttlingen, Germany
Biomaterials 31:523-31. 2010..Therefore, the CFR-PEEK based polymer-on-polymer articulations may be an alternative to polyethylene-on-metal and have a high potential for next generation disc replacements...
Modular titanium alloy neck adapter failures in hip replacement--failure mode analysis and influence of implant materialThomas M Grupp
Aesculap AG Research and Development, Tuttlingen, Germany
BMC Musculoskelet Disord 11:3. 2010..The failures of neck adapters were divided into 66% with small CCD of 130 degrees and 60% with head lengths of L or larger. Assuming an average time to failure of 2.8 years, the cumulative failure rate was calculated with 2.4%...
Biotribology of alternative bearing materials for unicompartmental knee arthroplastyThomas M Grupp
Aesculap AG Research and Development, Tuttlingen, Germany Ludwig Maximilian University Clinic for Orthopaedic Surgery, Campus Grosshadern, Munich, Germany
Acta Biomater 6:3601-10. 2010..Further in vitro wear simulations are necessary to establish knee design criteria in order to take advantage of the biotribiological properties of CFR-PEEK pitch for its beneficial use to patients...
[In vitro stability study of an improved implant system for minimally invasive transforaminal approach]S Schneid
Aesculap AG und Co KG, Forschung und Entwicklung, Am Aesculap Platz 1, 78532 Tuttlingen
Orthopade 31:488-93. 2002..The facet joint arthrodesis using resorbable pins reveals biomechanically interesting results and will therefore be investigated in further studies...
