Abstract: Embodiments of an orthopedic apparatus and method for using the orthopedic apparatus to correct rotational bone deformities are disclosed. Embodiments of the orthopedic apparatus include a stationary segment having a fixed portion engaged to a first bone portion and a track portion engaged to a mobile segment that is engaged to a second bone portion separated by the first bone portion by a growth plate such that the mobile segment migrates over time from a first position along the stationary segment to a second position along the stationary segment in such a way that torsional growth and correction of an angular deformity are promoted.

Abstract: A screw assembly and method developed for the fixation of femoral neck fractures without interruption of the growth process is disclosed. The screw assembly includes a male component that is attached to the lateral cortex and a female component that is attached at the proximal epiphysis. Anchorage of the components is achieved through screw-type fixation. The screw has a built-in feature that allows for free extension of its length as the fracture site or the slipped capital physeal plate heals and normal patient growth continues. Stable fixation and rotational stability are created at the fracture (slip) site while avoiding compression forces, thus avoiding premature closure of the physeal plate.

Abstract: A blade-plate assembly for performing an osteotomy procedure is disclosed. The blade-plate assembly may include a modular blade component configured to be coupled to either a Varus plate component or a Valgus plate component when performing the osteotomy procedure. In some embodiments, the modular blade component includes a support portion and a blade portion that extends outwardly in perpendicular relation to the support portion. The blade portion defines a channel configured to permit passage of a guide wire when performing the osteotomy procedure.

Abstract: An orthopedic device and method for correcting angular deformation of a bone structure having a growth plate. The device includes first and second hinge members connected together at a hinge joint. The device is adapted for mounting the orthopedic device to the bone structure with the pivot joint positioned over the growth plate. Alignment of the pivot joint with the growth plate promotes asymmetric growth of the growth plate to thereby correct the angular deformation.
