ABSTRACT
PURPOSE: Testing the new hip joint Helix3D efficiency through clinical data and walking parameters. METHOD: Three young hip-disarticulated patients (P1, P2 and P3) were assessed both with their previous prosthesis at first day, then four days and six months after being trained with a new prosthesis equipped with the Helix3D hip joint. Assessments comprised a satisfaction questionnaire, a two-minute walk test and a recording of main spatiotemporal gait parameters RESULTS: After four days with the Helix3D, the satisfaction for the prosthesis was improved for P1, unchanged for P2 and reduced for P3. Distance walked during two minutes increased for P1, unchanged for P2 and slightly improved for P3. Gait pattern was improved in P1, only. P1 abandoned the Helix3D at six months due to an ischiatic wound. P2 and P3 chose not to use the Helix at the end of the four days training period because they could not adapt to the Helix3D characteristics (hydraulic control of hip extension and assistance to hip flexion) and because they did not gain enough benefits. Despite much effort to adjust the prosthesis, the three patients definitively abandoned the Helix3D because of comfort problems, and decided to walk with their previous prosthesis equipped with a monocentric hip joint or even with crutches only. CONCLUSION: The Helix3D hip joint may need further developments to get clinically relevant for hip-disarticulated amputees who may also need a long training period to adapt to its technical characteristics.

We have investigated whether the levels of thrombin-activatable fibrinolysis inhibitor (TAFI) were correlated with D-dimer levels during pregnancy and at delivery. From the 10th week of pregnancy to delivery, 519 samples from 144 women (mean age 29.3 +/- 5, range 19-43) were obtained. We confirm the gradual increase of D-dimer levels, and provide reference intervals for D-dimer measurements throughout normal pregnancy. TAFI levels increased moderately during pregnancy but no inverse correlation with D-dimer levels was observed.
