Abstract: A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.

Abstract: A releasable attachment system is provided for use with a bone anchored post and related external prosthesis such as a prosthetic limb or the like, wherein the attachment system includes a safety release mechanism designed to release or break away when encountering an excess mechanical load. The bone anchored mounting post is implanted for direct affixation to patient bone, and carries or is connected to a fixator structure protruding through soft skin tissue and the like at the end or stump of an amputated limb for mechanical connection to the external prosthesis. The safety release mechanism accommodates substantially normal patient movement throughout a corresponding range of substantially normal mechanical loads, but releases in the presence of an excess load to prevent undesirable fracture failures.

Abstract: Systems and methods are provided for fixation of a fractured bone with an intramedullary bone fixation device. During an implantation procedure, the fixation device may be guided by a removable guidewire which is not coupled to the fixation device. The guidewire and device may be inserted into an intramedullary canal along a pathway which is not parallel to the intramedullary canal. The fixation device may be composite, formed of a support structure and a matrix material. The matrix material may be thermo-chemically activated, transformable from a deformable first thermo-chemical state to a hardened second thermo-chemical state. The fixation device may be radially expandable to deform to the shape of the intramedullary canal, to provide support to the fractured bone.

Abstract: An implantable segmented intramedullary structure adapted to be received in the intramedullary canal of a bone configurable between a relatively flexible, bent configuration for implantation or extraction and a relatively rigid, straightened configuration for bone treatment. The segmented intramedullary structure comprises a plurality of interconnected segments with a first interface and a complementarily-shaped second interface such that the first interface of a segment cooperatively engages the second interface of an adjacent segment. The segments define a channel for a tensioning member to lock the structure in a compressed configuration.
