OrthoPediatrics has filed a patent for an orthopedic apparatus that corrects rotational deformities and limb length discrepancies in bones. The system uses cable-couplings with linking members, such as posts or screws, that traverse the bones. The flexibility and adaptability of the system allow for installation at varying angles and locations, enabling growth arrest or rotational corrections. The patent also includes a method for limiting growth using cable-coupling systems. The device includes a bicortical post assembly and two coupling assemblies that flexibly conform to the bone’s side.

Orthopedic fixation device for altering bone growth
An orthopedic fixation device for altering the growth of a bone is described in a recently filed patent. The device consists of a bicortical post assembly with two telescopic monocortical posts, where one post can slide and rotate into the other. Additionally, there are two coupling assemblies that can flexibly conform to the side of the bone. Each coupling assembly has two retaining portions, with at least one adapted to receive and engage an extremity of the bicortical post assembly. The monocortical posts have cortical threaded portions adjacent to the retaining portions, as well as cannulations for guidance over a wire. The head portion of each post is designed to engage with the retaining portions of the coupling assembly, with the ability to freely rotate when inserted. The coupling assemblies are connected by a flexible tether, allowing them to move freely along its length. The position of the coupling assemblies is mirrored on either side of the growth plate, and the device is capable of stopping vertical growth of the bone.
In addition to the orthopedic fixation device, the patent also describes a coupling assembly that can be positioned on the side of a bone. This assembly consists of two couplings, each with an aperture for receiving a bone fastening element and tethering apertures. The couplings are linked by a flexible tethering member, which allows the couplings to conform to the side of the bone. The tethering apertures enable free translation of the flexible tethering member, and the aperture in each coupling allows for free rotation of the bone fastening element. The assembly may also include crimping elements to secure the flexible tethering member to the couplings, with the crimping element being a sphere that cannot pass through the tethering apertures.
The patent also includes a method for correcting limb length discrepancy or bone deformities using the growth plate. The method involves placing a coupling assembly on each side of the bone, adjusting the length between the couplings using the tethering member, and securing the couplings to the bone using fixing elements. A bicortical post assembly can be created by inserting a male monocortical post into a female monocortical post, allowing for sliding and pivoting motion.
Overall, this patent describes an orthopedic fixation device, a coupling assembly, and a method for correcting bone growth using a growth plate. The device and assembly provide flexibility and adjustability to accommodate different bone sizes and shapes, while the method offers a systematic approach to correcting limb length discrepancy or deformities.
