The coronoid process is one of the main constraints providing ulnohumeral joint stability. The coronoid process and the radial head provide a buttress against posterior displacement of the elbow joint. Fracture of the coronoid process can be either an isolated finding following elbow dislocation or part of a more complex fracture-dislocation. Much attention has been focused on treatment of radi...

Background. Gymnasts have high mechanical loading forces of up to 14 times body weight. Overuse lesions are typical in wrists and stress fractures in the olecranon, while isolated fractures of the coronoid process are uncommon. We present a case of retraumatized nonunion stress fracture of the ulnar coronoid process. Case Description. A 19-year-old gymnast presented with elbow pain after traini...

Introduction: Though fractures of the mandible are relatively common injuries, the coronoid process fractures have extremely rare occurance. Reports of longitudinal fracture of the coronoid process of the mandible are very rare. On literature search, only two previously reported cases of such type of fracture were found. Case Report: We report a very rarely occurring longitudinal fracture of th...

Coronoid process fractures are reported to occur from avulsion by the brachialis muscle or to be associated with elbow dislocations. We report a rare case of coronoid process fracture due to avulsion by the anterior bundle of the medial collateral ligament rendering the elbow unstable. In children, small fracture fragments of the coronoid process (types 1 & 2) are in reality often much larger b...

Approximately 2% to 15% of the patients with dislocated elbows are thought to present a fracture of the coronoid process of the ulna, but such a fracture does not often present in isolation. Its exact incidence is difficult to ascertain given the lack of studies on the subject. One case is presented of an isolated fracture of the coronoid process and it is placed in the context of the existing ...

OBJECTIVE To describe traumatic fracture of the medial coronoid process in dogs as a clinically distinct disease unrelated to congenital elbow dysplasia. METHODS Clinical records of dogs with acute, traumatic, unilateral lameness attributable to medial coronoid process disease were reviewed retrospectively. Clinical interpretation included findings on physical examination, orthopaedic examina...

PURPOSE To determine if specific coronoid fractures relate to specific overall traumatic elbow instability injury patterns and to depict any relationship on fracture maps and heat maps. METHODS We collected 110 computed tomography (CT) studies from patients with coronoid fractures. Fracture types and pattern of injury were characterized based on anteroposterior and lateral radiographs, 2- and...

A rare case of fracture of the coronoid and the pterygoid process caused by firearms is described. A 28-year-old male was hit by a bullet in the face, resulting in restricted mouth opening, difficulty in chewing and pain when opening the mouth. Clinical examination revealed a perforating wound in the right parotid region and a similar wound on the left side of the same region. A CT scan showed ...
