“…However, previous bone pin research has reported subjects did not experience significant discomfort. Subjects reported they moved their knees fieely and their waking and running styles remained unaffected (Lafortme, 1984;McClay, 1990;Lafortune et aL, 1992;Reinschrnidt, 1996; Reinschrnidt et a l ,…”

“…Lafortune (1984) conducted a similar bone pin investigation to examine three-dimensional tibiofemoral and patellofernoral kinernatics during normal wallMg and w i t h shoes modified with vams/valgus soles. Subjects were implanted with Steinman pins (2.5 mm diameter) affixed with target clusters into the adductor tubercle, into the lateral tibial condyle and Uito the midpatella (Lafortune, 1984;Lafortune et al, 1992;Lafortune et al, 1994). Each triad like the one in Figure ' A-2 contained four noncollinear spheres, one in the centre and three attached to orthogonal projecting rods (Lafortune et al, 1992).…”

“…Radiographs were subsequently taken with the implanted pins in order to record the position of the marken and define the tibial and femoral anatomical reference points (Lafortune et al, 1992). Since these anatomical landmarks c m be identified with great precision, an accurate description of skeletal movement is possible (Reinschmidt, 1996).…”

“…Radiographs with target marken were taken to defme the tibial and femoral anatomical CO-ordinate systems (McClay, 1990). McClay (1990) employed the exact DLT and transformation alg0nth.m~ as Lafortune (1992) to describe joint rotations and translations.

-A method is detailed allowing the computation of three-dimensional (3D) joint angles. Each joint of the equine digit is modelled as a sequence of three single axis rotary joints. The Joint Coordinate System was used; it involves a specific sequence of cardanic angles. The decomposition of the angles was chosen so that the three elementary angles coincide with the flexion/extension, passive abduction/adduction and lateral/medial rotations. The algorithms and kinematic procedures were described for the equine front digital joints. This method was tested in vitro on four forelimbs. For each limb, angle values were measured while the member was loaded by a press (from 500 to 6 000 N). These tests were repeated while a wedge raised one part of the hoof (toe, heel, lateral and medial sides) in order to induce modifications of the angular patterns of the joints. This method allowed a precise quantitative determination of 3D joint movements. The modifications occurring with the wedges are clearly identified and confirm some previously published semi-quantitative observations. Moreover, this method provides a way to collect objective data on the functional anatomy of joints and could be used to study connective shoeing thoroughly. It may be directly applied to other species and may be used by researchers interested in discreet articular movements, especially occurring in other planes than the sagittal one.horse / kinematics / digital joint / joint coordinate system / cardanic angles Vet.

A simple wear test was investigated for evaluating the wear and damage of material pairs when used in total knee replacement. The test consisted of an axially loaded metallic femoral indentor and a reciprocating ultrahigh molecular weight polyethylene (UHMWPE) flat disk that represented the tibial component. A number of variables were studied including the effect of conformity by varying the radii of the femoral surface, distilled water or serum as a lubricant, different femoral materials, and different types of UHMWPE. In general, the different morphologies of the surface wear of the UHMWPE were similar to those seen on retrieved total knee replacements. Increased conformity with a cylindrical indentor gave a reduced wear rate initially, compared with that of the lower conformity spherical indentor. However, the wear rates were similar subsequent to this initial wearing in phase. Transfer films of UHMWPE were observed on the cobalt-chrome indentors for both serum and distilled water lubrication, although this film was more extensive for distilled water. The lowest wear rate was observed when oxidized zirconium was used on the femoral side, which was attributed to greater wettability, surface hardness, and immunity to oxidative wear. Tests using cobalt-chrome femoral cylinders and different grades of UHMWPE showed different wear rates. Of these PEs, GUR 415 showed less wear than both RCH 1000 and UHMWPE containing numerous fusion defects. For the latter, wear was attributed to a fatigue mechanism, although in most cases it was associated with surface phenomena rather than subsurface cracking. However, in some specimens of UHMWPE subsurface crack propagations occurred with defects. The test method is discussed in relation to its applicability to the evaluation and comparison of bearing materials and surfaces, with particular application to total knee replacements.
