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: Embodiments provide an orthopedic apparatus that can include a tether member that is capable of engaging a bone using a plurality of coupling members. In some aspects, the tether member can include a central band that may be disposed between a distal member and a proximal member. The proximal member can define a proximal aperture and the distal member can define a distal aperture. Moreover, the distal member can be configured to be engaged to a fixed segment of the bone using at least one of the coupling members and the proximal coupling member can be configured to be engaged to a mobile segment of the bone using at least one other coupling member.
