Introduction: Degenerative disc disease is one of the most common reason for low back pain in a physical active population. The shape of the spine, especially reduction of lordosis, may have an important role in ethiology of lumbar disc degeneration. The aim of this study is to assess is there any differences within genders when evaluate lumbar spine and pelvic parameters in patients with a DDD. Materials and Methods: A prospective survey has been conducted in the Spine surgery department of Civil Hospital in Strasbourg (Service du Rachise, L'Hopital Civil, Strasbourg, France) during the period between January 1th, 2005 and December 31st, 2008. We have analyzed x rays and spino-pelvic parameters of 63 patients among of 80 patients with degenerative disc disease (DDD) of lumbar spine in which total disc arthroplasty (TDA) have been performed at one level. Standing lateral full spine x rays has been done before surgery and at final follow-up 3 years later. Following parameters were analyzed: lumbar lordosis (L1-S1), intervertebral angle, anterior and posterior disc height, sacral slope, pelvic tilt and pelvic incidence. Results : Mean follow-up time was 44 months. 45 females and 18 males patients with a mean age of 41,38 year were evaluated. The preoperative values of lumbar lordosis and sacral slope was significantly higher in a females with a DDD at L4-L5 segment. The same result has been seen and after the surgery. There have not been statistical differences these values between genders with DDD at L5-S1 segment, nor preoperatively, nor postoperatively. Conclusion : Although reduction of lordosis is pointed out as an important role for DDD we have not found that in our study that may suggest that DDD has complex etiology.

Objective. To describe the intrahepatic bile duct transposition (anatomical variation occurring in intrahepatic ducts) and to determine the frequency of this variation. Material and Methods. The researches were performed randomly on 100 livers of adults, both sexes. Main research methods were anatomical macrodissection. As a criterion for determination of variations in some parts of bile tree, we used the classification of Segmentatio hepatis according to Couinaud (1957) according to Terminologia Anatomica, Thieme Stuugart: Federative Committee on Anatomical Terminology, 1988. Results. Intrahepatic transposition of bile ducts was found in two cases (2%), out of total examined cases (100): right-left transposition (right segmental bile duct, originating from the segment VIII, joins the left liver duct-ductus hepaticus sinister) and left-right intrahepatic transposition (left segmental bile duct originating from the segment IV ends in right liver duct-ductus hepaticus dexter). Conclusion. Safety and success in liver transplantation to great extent depends on knowledge of anatomy and some common embryological anomalies in bile tree. Variations in bile tree were found in 24–43% of cases, out of which 1–22% are the variations of intrahepatic bile ducts. Therefore, good knowledge on ductal anatomy enables good planning, safe performance of therapeutic and operative procedures, and decreases the risk of intraoperative and postoperative complications.
