Embodiment Construction

[0067] This description of the preferred embodiment is intended to be taken in conjunction with the accompanying drawings which are considered a part of the entire written description. The drawings are not necessarily to scale and some features of the invention may be shown in exaggerated scale or in somewhat schematic form for the sake of clarity and conciseness. In the specification, relative terms such as "horizontal", "vertical", "upper", "lower", "top", "bottom" and their derivatives (for example, "horizontally", "downwardly", " upwardly", etc.) should be understood to mean a direction as then described or as shown in the figure in question. These relative terms are for convenience of description and generally are not intended to require a particular orientation. Terms including "inwardly" versus "outwardly," "longitudinally" versus "transversely," etc. are to be interpreted relative to each other or relative to an axis of extension, or an axis or center of rotation, as ...

Abstract

An intramedullary implant, system, and method for placement within a bone system are provided by the invention. The implant includes a body with at least one pair of beams arranged about a longitudinal axis of the body. The beams are each fixed to the body and each have an end. The end of one of the beams of a pair is releasably coupled to the other beam of the pair. The beams are each deflectable between (i) a coupled and biased position for insertion of the beams into a respective bone, and (ii) an uncoupled position for gripping bone. The beams of each pair in the uncoupled position being arranged so as to compressively engage the bone.

Description

technical field [0001] The disclosed devices, systems and methods relate to implants, and more particularly to implants for installation in appendages for the treatment of various skeletal disorders including hammer toe. Background technique [0002] Hammer toe is a deformation of the toe that affects the alignment of the bones adjacent to the proximal interphalangeal (PIP) joint. Hammer toe can be painful and can make walking or wearing shoes difficult. Hammer toe can often result in an open sore or wound on the foot. In some cases, surgery may be required to correct the deformity by fusing one or both of the PIP joint and the distal interphalangeal (DIP) joint. [0003] The most common corrective surgery involves placing pins or rods in the distal, middle, and proximal phalanges of the foot to fuse the PIP and DIP joints together. The pin or rod is cut outside the body at the tip of the toe. A plastic or polymer ball is placed over the exposed end of the rod, which rem...
