clavicle fracture classification

More recently, however, several studies have questioned if more clavicle fractures should be treated surgically. When describing a clavicle fractures note the location of the fracture along the shaft. clavicle shaft fractures are common traumatic injuries seen in young adults that occur in the middle third of the clavicle. 3. The AO classification of clavicular fractures along with the Neer classification system is one of the more frequently used classification systems when assessing distal clavicular fractures. The studies have suggested that people who ha… With the clavicle arbitrarily divided into thirds: 15% of fractures occur in the lateral third Infants can sometimes break their collarbones during the birth process.Seek prompt medical attention for a broken collarbone. A2 when the fracture is intra-articular, B1 when the fracture is extra-articular. Volume 32: Number 1; Supplement, January 2018. ... For example, if patients have a distal clavicle fracture with superior displacement of the proximal fragment, they should be referred to an orthopedic surgeon for consideration of surgical repair of the coracoclavicular ligament. Types 1. Background: Fractures of the distal third of the clavicle represent 10-30% of all clavicle fractures . Check for errors and try again. In light of this, ORIF is indicated. Nordqvist A, Petersson C: The incidence of fractures of the clavicle.Clin Orthop … I : Fracture line runs between the intact conoid and trapezoid ligaments, resulting in minimal fracture displacement 2. A direct hit to the collarbone can also cause a break. Group I are middle third fractures, Group II are lateral third fractures, and Group III are medial fractures. 1). Clavicle fractures are commonly known as a breaking of the collarbone, and they are usually a result of injury or trauma. Illustration of the Neer classification of distal clavicle fractures.

Common causes of a broken collarbone include falls, sports injuries and trauma from traffic accidents. 80% of clavicle fractures 2. A1 when the fracture is extra-articular. Occurs in 80% of clavicle fractures, making it the most common type off fracture. Check for errors and try again. The acromioclavicular (AC) joint remains intact. further subdivided Group II fractures into three distinct subgroups based on associated soft-tissue and ligamentous injuries. Comminuted Transverse- Line of Fracture is transverse. Type III intra-articular distal clavicular fracture extending into the acromioclavicular joint conoid ligament intact trapezoid ligament intact The compendium is branded as the AO/OTA or OTA/AO Fracture and Dislocation Classification Compendium. These fractures can then be further described based on fracture pattern, degree of shortening (overriding), and the degree of displacement, although these parameters were not part of Allman’s origi… The original classification by Neer in the 1960s described two types of distal clavicle fractures: type I, in which the coracoclavicular ligaments remain intact; and type II, in which the coracoclavicular ligaments are torn from the medial fragment and only the trapezoid ligament remains attached to the lateral fragment.23 The classification was later revised to include type III fractures, which involve extension into the AC joint; type IV fractures, which are seen in children and involve disruption of the periosteal sleev… For many decades, the results of nonsurgical treatment found that the majority of clavicle fractures healed more reliably with less of a complication rate when compared to clavicle fractures treated with surgery. AO Principles of Fracture Management. Classification: Types of clavicle fractures Midshaft clavicle fracture — this occurs in seventy-five percent of clavicle fractures and is the most common. More than two-thirds of cases are due to a fracture in the middle third of the clavicle (group I of the Allman classification). Fractures of the clavicle is typically described using the Allman classification system, dividing the clavicle into 3 groups based on location which was later revised by Neer(in which Group II was further classified into 3 types). FRACTURES OF THE CLAVICLE Le Kim Trong MD., Le Nghi Thanh Nhan MD. Allman Classification 1 Group I – Middle 1/3 Clavicle Fracture (80% of all clavicle fractures) Majority are non-operative except in cases of 100% displacement (essentially, a fracture where the two fragments do not overlap in a plane) Middle 1/3 clavicle fracture Classification.

In males, the annual incidence was highest Primary treatment Operative treatment methods were divided into fixation with anatomical plates, standard plates, hook plates, intramedullary fixations and other methods. Who In 1967 Allman8described the following classification system for all clavicle fractures based on location: Group I represented fractures of the middle third, which was the most frequent site of fracture (80%). Type I fracture occurs distal to the coracoclavicular (CC) ligaments (ie, trapezoid, conoid) and involves minimal fracture displacement. Middle 1/3 fractures 2. The classification system, broken into five categories communicates both the stability and treatment recommendation of the fracture focusing on the relationship of the fracture to coracoclavicular ligaments and the acromioclavicular joint. Distal 1/3 fractures 2. The most commonly encountered fractures, those of the middle third or midshaft of the clavicle, are classified as group I. Fractures of the distal third or acromial end of the clavicle are classified as group II, and fractures of the medial third or sternal end are classified as group III. 1. The clavicle is the most commonly broken bone in the human body, accounting for up to 5% to 10% of all fractures seen in hospital emergency admissions. Thus, assessment of the stability is essential for adequate treatment of these fractures. Clinical signs and symptoms of clavicle fracture include the following: 1. Type IIA fracture occurs medial to the conoid ligament. Treatment of distal clavicle fracture: a systematic review of treatment modalities in 425 fractures. treatment is controversial but may be nonoperative or operative based on the degree of displacement and patient factors. (2011) Archives of orthopaedic and trauma surgery. Crepitus from the fracture ends rubbing against each other may be noted with gentle manipulation 6.

Traditional treatment of midsha … II: Fracture line medial to coracoclavicular ligaments resulting in greater fracture displacement and higher incidence of nonunion. Traditionally, these fractures have been treated nonsurgically. 5 (2): 65-73. Group 1 1. Swelling, ecchymosis, and tenderness may be noted over the clavicle 4. Difficulty br… The Neer classification of clavicular fractures along with the AO classification system is one of the more frequently used classification systems when assessing clavicular fractures. The most common type of fracture occurs when a person falls horizontally on the shoulder or with an outstretched hand. The most common mechanism of injury is a fall onto the shoulder or onto an outstretched hand. to the undersurface of the medial clavicle at its costal tuberosity, and this insertion is often mistaken for medial clavicle fractures (Figure 5) [4]. INTRODUCTION Clavicle one of the most commonly fractured bones 2.6% - 5% of all fractures 35% - 45% of shoulder girdle fractures Postacchini F, Gumina S, De Santis P, Albo F: Epidemiology of clavicle fractures.J Shoulder Elbow Surg 2002;11:452-456. Clavicle Fractures 2. There are two articles on the e-medicine website: ‘Clavicle Fractures’ in the orthopaedic section and ‘Fractures, Clavicle’ in the emergency medicine section. Type I – Minimally displaced / interligamentous. Neer et al. Clavicle fractures are classified according to the fracture location with the use of the Allman classification. 15% of clavicle fractures 3. (2014) Journal of clinical orthopaedics and trauma. Transverse 2. 2. The former is extensive, well structured and includes the Allman classification, but is made up of large chunks of … Imaging of the Acromioclavicular Joint: Anatomy, Function, Pathologic Features, and Treatment. Allman (3) has classified clavicle fractures based on three anatomic regions (Fig. Type II – Displaced fractures, fracture medial to the coracoclavicular ligaments. Richard E. Buckley, Christopher G. Moran, Theerachai Apivatthakakul. Group I: Fractures of the middle third or midshaft fractures (the most common site), Fractures of the clavicle can be classified by its anatomical location (Table 1): Table 1: Stellate 3. Classification of Fracture. The coracoclavicular ligament is a vertical stabilizing structure for the acromioclavicular joint and plays an integral part in clavicle fracture classification. (2020) RadioGraphics. Frequently, these fractures result in instability due to a combination of bony and ligamentous injury. 1)[3]. {"url":"/signup-modal-props.json?lang=us\u0026email="}, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":74187,"mcqUrl":"https://radiopaedia.org/articles/neer-classification-of-clavicle-fractures/questions/1890?lang=us"}. Oh JH, Kim SH, Lee JH, Shin SH, Gong HS. Fractures of the middle third, or midshaft, are the most common, accounting for up to 80% of all clavicle fractures. Look for angulation and/or displacement of the fracture. The clavicle acts to transmit forces from the upper limb to the axial skeleton. When an orthopaedic surgeon is evaluating a clavicle fracture he or she tries to classify the type of fracture into one of three groups: Group I: the clavicle is fractured in the middle of the bone. Dyan V. Flores, Paola Kuenzer Goes, Catalina Mejía Gómez, Darwin Fernández Umpire, Mini N. Pathria. Group 2 1. Your collarbone connects the upper part of your breastbone to your shoulder blade. The proximal and distal ends of the clavicle are secured by the intact ligamentous and muscular attachments. In publications, it will be cited as Meinberg E, Agel J, Roberts C, et al. The classification system, broken into three categories focuses on the displacement and pattern of the fracture and the integrity of the coracoclavicular ligaments.
