Anatomical humeral fixation system and method

摘要

An anatomical shoulder fixation system comprises a lower portion and an upper portion, the lower portion being a separate part and being coupled to the upper portion adjustably. For example, the relative position of the upper portion to the fixation system is capable of rotating and translating with relation to the lower part, accommodating placement on a shoulder even if displacement of the lesser tuberosity and the greater tuberosity due to fracture or dislocation. Examples include a flexible upper portion coupled to a lower portion or a more rigid upper portion joined to a lower portion, and combinations of these. In both examples, screws may be used to fix the lower portion prior to completing the displacement and fixation of the upper portion. For example, the lower portion may provide structures for attaching sutures, suitable for use with a curved needle shaft and suture.

主权项

1. An anatomical fixation system for repairing damage to soft tissues, bone or soft tissues and bone, comprising:
a one piece stem having a head portion and a distal end, the head portion having an anchor portion extending into aperture, the anchor portion having an elongated portion, the stem having an inner surface adapted for mounting to the bone; and a leaf having one end having a slot and an opposite end, the opposite end adapted to couple to the soft tissue, such that the stem and the leaf are cooperatively engaged and soft tissues coupled to the upper portion are retained in place relative to bone coupled to the stem, wherein the anchor prevents translational motion, angular rotation or both translational motion and angular rotation of the leaf relative to the stem in at least in one translational or angular direction.
