The variations which occur in the medial and lateral ligament complexes of the elbow were investigated.
These occurred frequently with the standard appearances occurring in no more than half the specimens on
the medial side and one quarter of those on the lateral side. Surgeons who regularly perform elbow
arthroplasty must be aware of these considerations, especially with the introduction of unconstrained
prostheses which rely upon the ligament complex for their postoperative stability.
