The first, pro-posed by Regan and Morrey,22 was based on the height of the coronoid fragment (Figure 3). Visualised or self reported malocclusion is the key to diagnosis. Olecranon Process Fracture Orthobullets It is designed for grasping for precise movements and serving as a tactile organ. Nonsurgical treatment involves using a splint or sling for a few days, followed by an early and gradual increase in elbow and wrist movement (depending on the level of pain). O’Driscoll SW, Jupiter JB, Cohen MS, Ring D, McKee MD. Coronoid fractures can be challenging to understand and treat. He has pain and swelling at the elbow without evidence of instability. Orthobullets dorsal extrinsic dorsal intercarpal ligaments dic the dorsal intercarpal ligament originates from the dorsum of the triquetrum and inserts on the dorsal aspects of the trapezoid and the waist of the scaphoid. Stable. coronoid fracture; olecranon fracture; elbow dislocation. 47. Coracoid fractures are usually seen with other fractures of the scapula or shoulder region; isolated coracoid fractures are rare . Coronoid fractures are seen in 10-15% of elbow dislocations; This particular injury pattern is secondary to a fall on an outstretched hand with the shoulder in a flexed, adducted position, resulting in an axial force combined with varus, posteromedial rotational stress; The injury typically results in elbow subluxation with associated anteromedial facet coronoid fracture. An olecranon fracture is a break in the bony "tip" of the elbow. Obvious deformity is likely present if the elbow is dislocated.

Illustrations of the coronoid fracture according to the classification of. The nose is the most frequently injured facial structure, undoubtedly because of its prominent position on the face. MB BULLETS Step 1 For 1st and 2nd Year Med Students. 1. When olecranon or coronoid fracture is associated with elbow dislocation, … The type II or III fracture may be comminuted, and all three may be associated … The mechanism of injury that produces different reproducible fracture patterns has also been used as a functional classification. ORTHO BULLETS Orthopaedic Surgeons & Providers 7 In flexion type injuries the rare avulsion fracture and the much more frequent metaphyseal fractures of the olecranon occur. scaphoid fracture; Anatomy: Osteology . It consists of an anterior coronoid process and an anteromedial facet. Computed tomography can be used if clinical signs suggest a fracture but plain X-ray appears normal. However, many different etiologies can cause instability: trauma or microtrauma, rheumatic disease, neurological injury, congenital causes, and infection. Isolated fractures of the coronoid process are extremely rare. In the past, coronoid fractures were treated with a longer period of immobilization (3-4 weeks) in greater degrees of flexion, and this was believed to be a better alternative than operative treatment. Large coronoid fragments and extensive comminution of the trochlear notch did not preclude a good result provided that stable, anatomic fixation was achieved. This was a retrospective study of 19 patients with AMF fractures between 2010 and 2012. Coronoid Process Fracture. Orthobullets Techniques are largerly incomplete at this time, and will see rapid improvement as they are updated by experts in the field over the coming months. Shaft. 3-A A small coronoid fracture is seen on a lateral radiograph of the elbow. In total, they have an incidence of about 1–2% of all elbow fractures. Treatment of a fractured coronoid is an essential element of managing complex elbow instability. A "plough fracture is an isolated anterior arch fracture caused by a force driving the odontoid through the anterior arch. Fractures of the coracoid process are uncommon, comprising approximately 13% of all scapular fractures and 5% of all shoulder fractures (19,20). Dr. Cohen is a Professor of Orthopaedics and Director of the Hand & Elbow Surgery Department at Rush University Medical Center. The elbow is composed of three articulations: 1. The hand is the distal functional tool of the upper limb an important organ for day to day functions. Treat with halo vest (successful in 75%), mm (8.1mm with radiographic magnification) then a, is assured and the injury pattern is considered unstable, controversy exists around optimal form of immobilization, posterior C1-C2 fusion vs. occipitocervical fusion, may consider preoperative traction to reduce displaced lateral masses, preserves motion compared to occipitocervical fusion, C1 lateral mass / C2 pedicle screw construct, may be sufficient if adequate purchase with C1 lateral mass screws, uses when unable to obtain adequate purchase of C1 (comminuted C1 fracture), higher rate of complications in patients with delayed C-spine clearance so it is important to clear expeditiously, - Atlas Fractures & Transverse Ligament Injuries, Occipitocervical Instability & Dislocation, Traumatic Spondylolisthesis of Axis (Hangman's Fracture), Cervical Lateral Mass Fracture Separation, Extension Teardrop Fracture Cervical Spine, Clay-shoveler Fracture (Cervical Spinous Process FX), Chance Fracture (flexion-distraction injury), Osteoporotic Vertebral Compression Fracture, Ossification Posterior Longitudinal Ligament, DISH (Diffuse Idiopathic Skeletal Hyperostosis), Atlantoaxial Rotatory Displacement (AARD), Pediatric Spondylolysis & Spondylolisthesis, occipital-cervical junction and atlantoaxial junction are coupled, primary stabilizer of atlantoaxial junction, relatively strong and contributes to occipitalcervical stability, < 3 mm = normal in adult (< 5mm normal in child), 3-5 mm = injury to transverse ligament with intact alar and apical ligaments, > 5 mm = injury to transverse, alar ligament, and tectorial membrane, open-mouth odontoid view important to identify atlas fractures, study of choice to delineate fracture pattern and identify associated injuries in the cervical spine, more sensitive at detecting injury to transverse ligament. Clicking may also occur with movement of the arm.

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. terrible triad injury . Coronoid process fractures have been classified into three types within the Regan and Morrey classification system 1: 1. type 1:avulsion of the tip of the coronoid process 2. type 2:fragment involving <50% of the coronoid process 3. type 3:fragment involving >50% of the coronoid process The more clinically relevant and more widely adopted by orthop… A type III fracture involves more than half of the coronoid process. If intact, hard collar.

Beyond the level of the coronoid, however, a tension band wire construct cannot provide sufficient rotational control. Additional condyle fractures should be always suspected if a fracture of the mandibular body is present.
