Radiological evaluationshows sagittal shelter significantly superior,sacral slope significantly lower and the type 1 oflumbar lordosis more frequent in chronic low backpain women compared to healthy women.discussion-conclusionIn menopausal women, chronic low back painseems to be associated with lower sacal slope,the type 1 of lumbar lordosis more frequent andbehindly projection of pressure center.one patient (2 hips). Coxa vara recurred in 7 hips.In 4 of these hips, repeat surgery with hypervalgusosteotomy was indicated to stop epiphysealslipping (3 hips) or to improve the arc of motion(1 hip). Functional outcomes were poor in coxavara associated with poor epiphyseal development(nonossified or fragmented epiphysis) as seen inspondyloepiphyseal dysplasia congenita, spondyloepimetaphysealdysplasia, Kniest disease, andmultiple epiphyseal dysplasia. Coxa vara with physealinstability as observed in spondylometaphysealdysplasia resulted in deformity recurrence postoperativelyduring growth. In contrast, outcomewas better in cases of coxa vara with nonphyseal/nonepiphyseal involvement, that is, good femoralhead morphology, stable physis, and good articularcartilage, as seen in cases of metaphyseal dysplasiaand cleidocranial dysplasia.Conclusions8- coxa vara in chondrodysplasia: prognosisstudy of 35 hips in 19 childrenTrigui M, Pannier S, Finidori G, Padovani JP, Glorion C.Department of Orthopaedic Surgery, Habib Bourguiba Hospital, Sfax, Tunisia.dr_moez_trigui@yahoo.frJ Pediatr Orthop. 2008 Sep;28(6):599-606.BackgroundTo better understand anatomical and functionaloutcomes of coxa vara in chondrodysplasia accordingto the initial presenting hip morphology,disease type, and impact of surgery.Coxa vara with physeal and epiphyseal involvementand severe impairment of the articularcartilage has a poor prognosis even after reconstructivesurgery. In coxa vara with an abnormalphysis, there were numerous postsurgical recurrencesof the deformity during growth if the physiswas not stabilized at the time of valgus osteotomy.In these cases, we should delay osteotomy untilan HEA greater than 60 degrees. Coxa vara inwhich only the metaphysis of the femoral neckis involved, the deformity is milder and often requiresno treatment. Indications for surgery in thisgroup are increasing coxa vara, Trendelenburggait, or an HEA greater than 60 degrees.216methodsClinical and radiographic records of 19 children(35 hips) diagnosed with coxa vara and with osteochondrodysplasiawere reviewed. We classified thehip radiographic findings into 2 groups: (a) groupI, coxa vara with a fragmented and/or nonossifiedhead; and (b) group II, coxa vara with a regularfemoral head. Surgical indications in coxa varaincluded decreased range of hip motion (usuallydiminished abduction, extension, and internal rotation),coxa vara with progression documented onregular follow-up hip radiographs, and/or severecoxa vara with a Hilgenreiner epiphyseal angle(HEA) of 60 degrees or more. Follow-up was untilthe completion of growth and, for some patients,into early adulthood. Mean follow-up was 8 years.resultsTwenty-five hips were operated on in 13 patients.In 23 hips, the procedure was a valgus osteotomyfixed by pins and wire. A pelvic extension osteotomywithout valgus osteotomy was performed in9- Association of spinal deformities withheavy metal bioaccumulation in naturalpopulations of grass goby, Zosterisessorophiocephalus pallas, 1811 from the Gulfof Gabès (Tunisia)Messaoudi I, Deli T, Kessabi K, Barhoumi S, Kerkeni A, Saïd K.UR 09/30: Génétique, Biodiversité et Valorisation des Bioressources,Institut Supérieur de Biotechnologie, 5000, Monastir, Tunisia, imed_messaoudi@yahoo.fr.Environ Monit Assess. 2008 Aug 16.The present study illustrates an analysis of spinaldeformities associated with metal accumulation innatural populations of Zosterisessor ophiocephalusderived from polluted (S1) and unpolluted(S2) areas in the Gulf of Gabès in Tunisia. Threebasic types of spinal deformities were detected:kyphosis, scoliosis and lordosis. These basic deformitiesfrequently co-occur. Spinal deformitieswere observed in 10.72% of the total examinedfish (n = 494). Deformed fish were 3.85 times
