Total shoulder replacements should, as far as possible, be designed after normal anatomy. A small mismatch in curvature between the humeral head and glenoid surfaces may reduce edge loading when the humerus translates on the glenoid, but ma...
Enhanced bone ingrowth and fixation strength with hydroxyapatite-coated porous implants [0.03%]
羟基磷灰石涂覆多孔假体促进骨长入及假体固定强度的提高
