Viewed laterally, the rostrodorsal edge of the supra-angular articulates with the caudolateral edge of the coronoid and the rostrolateral edge invests the dentary (Figures 2A and B).
The dentary, coronoid and supra-angular present ossification centers in stage 16, with greater dye retention in the dentary, indicating that this element is the first to present an ossification center (Figures 3A, B and 4A).
Lower jaw with an outer row of enlarged curved spaced canines from symphysis to bend of dentary and directed somewhat anterodorsally, 1-2 irregular inner rows of smaller curved teeth at symphysis grading to a single row laterally and continuing to mid-height of coronoid
process of dentary.
The syndrome of "terrible triad of the elbow" is a severe pattern of injury that consists of an ulnohumeral dislocation associated with the fractures of the radial head and the coronoid
process of the ulna (1) (Fig.
4) Associated fractures include radial head, radial neck, coronoid
, epicondyles, and unrecognized osteochondral fractures.
Similarly, if osteophyte formation occurs in the trochlea or in the coronoid
process, impingement pain may be noted in extreme flexion.
Primary repair is generally reserved for an acute tear related to a defined traumatic event in which the MCL is avulsed from the humeral or coronoid
A few reports of tooth displacement in the maxillary sinus, nasal cavity, orbit, chin, mandibular ramus, condyle, and coronoid
process have been published.
The anterior capsule extends proximally to the coronoid
and radial fossae and distally to the anterior margin of the coranoid process and annular ligament.
Elbow dislocations can be associated with radial head fractures, coronoid
fractures, capitellar or trochlear fractures, olecranon fractures, or any combination of these (Fig.
One of these patients additionally had a coronoid
fracture and another an olecranon and coronoid
The third and final screw was inserted through the plate into the coronoid
process to supplement the rigidity of the construction (Fig.
