With arthroscopy , it is difficult to evaluate injury to the volar extrinsic ligaments , including the radioscaphocapitate and long radiolunate ligaments , because these ligaments may be pulled taut with the longitudinal traction necessary for entry of the arthroscope ( Geissler , 1996 ) . The technique involved three steps : first , the identification and preservation of the hypogastric nerve in a loose tissue sheath underneath the ureter and lateral to the sacro-uterine ligaments ; second , the inferior hypogastric plexus in the parametrium is lateralized and avoided during parametrial transsection ; third , the most distal part of the inferior hypogastric plexus is preserved during the dissection of the posterior part of the vesico-uterine ligament . Both intrinsic and extrinsic ligaments of the wrist and hand further stabilize the carpal bones . Extrinsic ligaments span the radiocarpal joint , while intrinsic ligaments connect between individual carpal bones . This type of instability is seen in wrists with rheumatoid arthritis after chronic attrition of radial-sided extrinsic ligaments and bony changes . Within weeks , it shrinks down to form a little ligament ( the ligamentum arteriosum ) linking the pulmonary artery and the Aorta . At around eight years the anterior cruiciate ligament broke in his right rear leg . There are many more extrinsic ligaments on the volar aspect of the wrist . This allows us to limit the injury to overlying ligaments and muscles , which can occur with ' open ' spine surgery .
