Abstract

A clamp assembly for orthopedic use having a housing that includes a top surface, a recess, a distal base and a bottom surface, the recess defining a longitudinal axis and extending through the housing from the top surface through the distal base and toward the bottom surface, and at least two through slots, each one of being disposed at a bottom or a side a surface of the housing. The assembly including a securement assembly positionable within the recess in a co-axial relationship to a mating surface on the recess, and a band sized for travel along a predetermined path defined in part by the through slots in the housing, wherein at least one of the through slots is a starting point for travel of the band along the predetermined path.

Core Innovation

The disclosed orthopedic stabilization apparatus includes a first clamp assembly configured to receive one of first and second surgical rods, and a second clamp assembly configured to receive one of the first and second surgical rods. A tether band is provided with a first end and a second end, and the first end of the tether band is split into a first strand portion fixed to the first clamp assembly and a second strand portion fixed to the second clamp assembly.

The tether band includes a second end having a first unsplit portion. The first unsplit portion of the second end is splittable into third and fourth strand portions, so that strand portions are associated with each of the clamp assemblies at the first end and additional splittable strand portions are provided at the second end.

Each clamp assembly includes through slots and a securement assembly that applies compressive force to secure a flexible tether band to the housing after tensioning. The clamp housing defines a recess with a longitudinal axis and a mating engagement surface for securement, and locking features are described for provisional and final locking.

Claims Coverage

The provided claim set contains 1 independent claim. The main inventive features focus on the tether band having a split first end fixed to first and second clamp assemblies and a splittable unsplit second end, together with clamp structural details using through slots and screws to retain the selected surgical rods.

Overall claim coverage centers on an orthopedic stabilization apparatus that combines first and second clamp assemblies receiving surgical rods with a tether band whose first end is split into strand portions fixed to the respective clamp assemblies and whose second end includes an unsplit portion that is splittable into additional strand portions; dependent claims further add through slots and screws for retaining the selected rods in each clamp assembly.
