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.
