What is the Coronoid process attached to?
What is the Coronoid process attached to?
The coronoid process is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and of considerable strength. Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus.
What is a coronoid process fracture?
Fracture of the coronoid process is thought to result from elbow hyperextension with either avulsion of the brachialis tendon insertion or shearing off by the trochlea 1.
What is the classification system for Coronoid fractures?
Coronoid process fractures have been classified into three types within the Regan and Morrey classification system 1: type 1: avulsion of the tip of the coronoid process. type 2: fragment involving <50% of the coronoid process. type 3: fragment involving >50% of the coronoid process.
What is the terrible triad of the elbow?
The terrible triad of the elbow consists of a combination of an elbow dislocation, a radial head fracture, and a coronoid process fracture. This situation almost always renders the elbow unstable, making surgical fixation necessary.
How many Coronoid processes are there?
The coronoid process and condyloid process are located at the superior aspect of the ramus. The coronoid process is anterior and the condyloid process is posterior; the two are separated by the mandibular notch. The ramus is bound by two surfaces and four borders and contains two processes.
What is the function of temporal muscle?
The temporalis muscle runs superficially, from the temporal bone to the coronoid process of mandible. The main function of this muscle is to produce the movements of the mandible at the temporomandibular joint and thus facilitate the act of mastication.
How do you fix a coronoid process?
Large coronoid fractures can be rigidly fixed and small or comminuted fractures can be fixed with suturing the bone and anterior capsule to the anterior ulna using pull out sutures or suture anchors. The rare small fragments with no soft tissue attachments can be excised.
