Embodiment Construction

[0019] The present invention relates to an expander plate 10 for treating angulated and / or rotational deformities of the growth plate. It should be noted, however, that although directional indicia (eg, top, bottom, front, rear, sides) are used to describe exemplary embodiments of the present invention, the directional indicia used herein do not define any particular direction, but rather Refers to the surface relative to the plate 10 . For example, bottom refers to the surface facing the bone, top refers to the surface facing away from the bone, front refers to the first longitudinal end, and rear refers to the second longitudinal end, and side refers to the plate 10 along the longitudinal axis of the plate 10. s surface.

[0020] In one embodiment, such as figure 1 with figure 2 As shown in , the expansion board 10 includes a socket base portion 20 , an insertion slide portion 30 and a slider collar 40 . The insertion part 30 is slidably accommodated in the sleeve part ...

Abstract

A ratcheting epiphysiodesis plate comprises a female base half (20) having a ratchet arm (230) and a male sliding half (30) having a series of ratchet teeth (312), the male sliding half being slidably connected to the female base half with the ratchet arm engaging the ratchet teeth, one of the female and male sliding halves including a first fixation element receiving hole (222), (322) for receiving therethrough a fixation element for binding the plate to a bone. The plate may further comprise a slider band (40) slidably connected to the female base half over the ratchet arm, or a plurality of female base halves with ratchet arms of different lengths, in order to adjust the preset load required to release the ratchet arms from the ratchet teeth.

Description

technical field [0001] The present invention generally relates to a plate for correcting deformities of the skeletal growth plate. More particularly, the present invention relates to a ratcheting epiphysiodesis plate and a method of treating growth plate deformities using the ratcheting epiphysiodesis plate. Background technique [0002] During childhood, sometimes one side of the growth plate grows faster than the other, causing angular or rotational deformities of the bones. Traditional methods of treating angular deformities of the growth plate involve inserting staples, Kirchner wires, or screws into the growth plate to inhibit or temporarily stop growth on one side while allowing growth on the other side and correcting the angular deformity . However, in some cases, the restricted side of the growth plate may fuse and close while the other side of the growth plate is still growing, thus causing deformity in the opposite direction. Contents of the invention [0003]...
