Epidemiology: These are uncommon fractures; they are typically associated with posterior elbow dislocation. describe key steps of the operation verbally to attending prior to beginning of case. Large coronoid fragments and extensive comminution of the trochlear notch did not preclude a good result provided that stable, anatomic fixation was achieved. A. Outpatient Evaluation and Management . Bado Classification Stable internal fixation with figure-of-eight tension-band wire fixation for simple transverse fractures allows early motion to minimize stiffness. Fracture Reduction and Provisional Fixation. Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone.In about 60% of cases the break occurs in two places. Coronoid fractures can be challenging to understand and treat. He has pain and swelling at the elbow without evidence of instability. Proximal radioulnar joint The ulnohumeral joint, along with the LCL and MCL, is considered a primary stabilizer of the elbow.4,5 The coronoid makes up the distal aspect of the ulnohumeral joint and articulates with the trochlea. Fig. 47. 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. 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. Most frequently they are a result of a fracture dislocation of the elbow joint. PREOPERATIVE PLANNING. elbow joint contains two articulations .

In total, they have an incidence of about 1–2% of all elbow fractures. 23 A, Type 1. O’Driscoll et al. Type I is a fracture of the tip of the coronoid process caused by a shearing force as the coronoid process subluxates or dislocates over the trochlea.

Although traditionally the mandible and base of skull are thought to form a complete bony ring, interrupted only by the TMJs.This should mean that the mandible should fracture in two places (akin to the bony pelvis) making single fractures uncommon, but this in fact not the case, with ~40% of fractures being unifocal. Coronoid fractures were once thought to be inconsequential.

Background: Fracture of the anteromedial facet of the coronoid was recently recognized as a distinct type of coro- noid fracture resulting from a varus posteromedial rotational injury force. This was a retrospective study of 19 patients with AMF fractures between 2010 and 2012. 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. 0.

Treatment of a fractured coronoid is an essential element of managing complex elbow instability. 3-A A small coronoid fracture is seen on a lateral radiograph of the elbow. 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.

A displaced coronoid fracture that presents with a block to elbow motion is a definite indication for surgical stabilization. The mechanism of injury that produces different reproducible fracture patterns has also been used as a functional classification. 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… To 10 % of paediatric elbow fractures Trauma or microtrauma, rheumatic disease, neurological injury congenital.
