Abstract: A joint orthosis includes upper and lower members, and a joint mechanism. The joint mechanism includes a shielding cover and at least one of modular front and rear inserts. Each of the modular front and rear inserts is disposed to limit movement of a joint of a human body in a flexion/extension direction. The shielding cover is removably attached to a mounting frame of the joint mechanism and is configured to conceal and prevent access to the at least one or the modular front and rear inserts.

Abstract: A hinge for an orthopedic brace includes: a pivot shaft; a lower leg plate pivoted to the pivot shaft; an upper leg plate; a catch plate having a toothed peripheral edge; and two position adjusting units, each of which includes a rotatable limiting seat, a limiting pin, and a slider body. The rotatable limiting seat defines a housing chamber therein, and is formed with a wall slot. The slider body is slidably disposed in the housing chamber. The limiting pin extends from the slider body through the wall slot for engaging and disengaging the toothed peripheral edge. The catch plate is formed with a guiding groove. The rotatable limiting seat has a tongue protruding into the guiding groove.

Abstract: A buckle assembly includes female and male buckle plates. The female buckle plate is formed with an insertion slot defined by a slot-defining wall having first and second wall faces, and has first and second corners. The first and second corners oppose each other, and are different in height with respect to a reference plane. The male buckle plate has a bent end portion that has upper and lower segments and a middle segment cooperating with the upper and lower segments to define upper and lower corners. The bent end portion is pivotable to the first corner by abutting the upper corner against the first corner, such that the bent end portion is rotatable relative to the first corner.
