AI Technical Summary

Problems solved by technology

Bone screws that are angled relative to the plate are often some distance away from achieving adequate engagement with the bone, which can severely limit proper fixation and cause damage to surrounding soft tissue

Embodiment Construction

[0023] This description of the preferred embodiments is intended to be read in conjunction with the accompanying drawings, which are to be considered a part of the entire written description of the invention. The drawings are not necessarily to scale and certain features of the invention may be exaggerated in scale or in schematic form for the sake of clarity and conciseness. In descriptions such as "horizontal", "vertical", "upward", "downward", "top" and "bottom" and their derivatives (for example, horizontally, downwardly, upwardly, etc. ) relative terms should be construed to refer to the orientations shown in the subsequent description or in the drawings discussed below. These relative terms are for ease of description and do not imply that a particular orientation is required. Terms including "inwardly" versus "outwardly," "longitudinally" versus "transversely" are to be interpreted relative to each other or to an elongated shank, or an axis or center of rotation, as th...

Abstract

An ankle arthrodesis fusion plate is provided that affords compression across the tibio-talar joint to promote bone fusion and joint stability.

Description

technical field [0001] The present invention relates to devices for fusion of damaged, deteriorated or fractured tibia, talus and calcaneus in the ankle region. Background technique [0002] Arthrodesis is the surgical fixation of a joint, which eventually leads to bone fusion. Basically, the procedure is artificially guided ankylosis to relieve pain or provide support in a diseased or injured joint. Tibiotalcocalcaneal arthrodesis, or tibiocalcaneal arthrodesis ("TC"), is used for arthritic ankles and subtalar joints such as Charcot's disease. Salvage procedure resulting in joint disease or treatment of pain and dysfunction. In performing ankle and subtalar arthrodesis, the surgeon typically wishes to achieve anatomical alignment, pain relief, and a stable, walking foot. Achieving proper fixation while protecting the surrounding soft tissue is critical to a successful outcome. [0003] Bone plates, often used in TC, are plates that can be fixed to the surface of the bon...
