An intramedullary aligned bone cutting jig for elbow replacement

One of the main post operative complications of total elbow replacement has been dislocation and fracture of the olecranon. This has been associated with rotational malalignment of the bone cuts of the proximal ulna caused by the current free hand cutting method. This paper presents an intramedullary aligned bone cutting jig which gives rotational location on the ulna for the bone cuts, without notching the olecranon.
