Rôle biomécanique des ligaments sacroépineux et sacrotubéral sur la stabilité de l’articulation sacro-iliaque

OBJECTIVES Surgery of pudendal nerve entrapment needs the section of both sacrospinal and sacrotuberal ligaments. We asked about the potential side effect of such a section especially on sacro-iliac joint stability. MATERIAL AND METHODS We performed a cadaveric anatomical and biomechanical study concerning six sacro-iliac joints. Joints were tested on a plateform, and results were analysed with a logiciel (Medai((R))), both especially developped for, before and after sacrospinal and sacrotuberal section. RESULTS The computered analysis of our results proved that sacro-iliac joint has a significant range of motion, specially in youngs. Results obtained confirmed that there is no statistical difference (p
