If left untreated, the bony fragment can cause mechanical block to elbow flexion by obstructing the coronoid

processors will feature in medical journals around the world.
Osteology of the coronoid
process with clinical correlation to coronoid
fractures in terrible triad injuries.
Eight cases had a concomitant distal ulnar fracture, while 6 cases were associated with other injuries--lower limb fractures or ligament sprains (4 cases), homolateral coronoid
fracture (1 case) and contralateral radial capitellum fracture (1 case).
The aim should to place the lateral parallel to metaphyseal flare of lateral cortex and second diverging pin should cross the fracture site at medial edge of coronoid
fossa, as described by Hamdi et al11.
1) The most common sites are the long tubular bones, especially the femur, humerus, and tibia) In the maxillofacial region, they are most common in the mandible, the condylar area, and the tip of the coronoid
, articular and angular process located high in the mandible, and the latter is high and verticalized.
The stratum corneum is hyperkeratotic with a thin column of poorly staining parakeratotic cells the coronoid
lamella running through the surrounding normal staining cells.
Fragmented medial coronoid
process of the ulna in the dog.
The other sites for ectopic mandibular third molars include: the ramus, coronoid
process, sigmoid notch and lower border of the mandible (2).
Clinical evaluation and computed tomography of his head and face revealed a small intraparenchymal hemorrhage of the right posterior temporal lobe, as well as a comminuted left parasymphyseal fracture and a displaced left mandibular angle fracture extending up thru the coronoid
process (Figure 1).
Dissection Procedure: The attachment of the masseter muscle from the zygomatic arch was resected and the muscle was reflected downward, detaching from the lateral surface of the mandible to expose the coronoid
process and ramus of the mandible.

The two halves of the mandible are fused, indicating no limit between them, and comprise: (1) the coronoid
, (2) the dentary, and (3) the supra-angular.
