Reconstruction of the Coronoid Process Using the Tip of the Ipsilateral Olecranon

Abstract

Reconstruction of the coronoid using the tip of the ipsilateral olecranon was an effective method for restoring normal kinematics over a range of elbow motion from 20° to 120° in a cadaveric model of an elbow with a 40% coronoid deficiency. This reconstruction technique may prove beneficial for patients with elbow instability due to coronoid deficiency.

Clinical anatomy and biomechanics of the elbow

“…Alolabi et al showed that reconstruction of the coronoid using the tip of the ipsilateral olecranon was an effective method for restoring normal kinematics over a range of elbow motion from 20 to 120 in a cadaveric model of an elbow with a 40% coronoid deficiency. 39…”

Osteochondral coronoid allograft in chronic coronoid process bone loss reconstruction: an original technique with encouraging clinical and radiological outcomes at a mid-term follow-up

“…Only a biomechanical in vitro study conducted by Alolabi et al 1 showed the possibility of properly correcting the technique by modifying the direction of the osteotomy, but to date clinicians do not have proper clinical outcomes to recommend this procedure. However, using a healthy portion of an unstable elbow to make it stable again should be accurately planned before starting the procedure.…”

Reconstruction of coronoid process of the ulna: a literature review

“…They found that excision of 50% of the olecranon exerted no significant effect on elbow joint stability, including varus, valgus, and rotation. Alolabi et al 23 comparatively analyzed the biomechanics among the intact ulna, partial excision of the coronoid process (40%) and partial excision of the coronoid process (40%) combined. Ramirez et al 24 conducted a biomechanics experiment and obtained findings consistent with those of Alolabi et al 23 However, they made certain modifications, such as complete excision of the coronoid process and use of an identically sized olecranon osteotomy for reconstruction.…”
