Clavicle Classifications ShoulderDo

The anatomic site of the fracture is typically described using the Allman classification, which divides the clavicle into thirds. 3 Group I (midshaft) fractures occur on the middle third of the.. Craig's classification had the greatest prognostic value for lateral third fractures, and Robinson's classification had the greatest prognostic value for middle third fractures. Fractures of the clavicle are common injuries but non-union is an uncommon occurrence 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). Group I: Fractures of the middle third or midshaft fractures (the most common site) Allman classification of clavicle fractures 9; Robinson classification of clavicle fractures 9; Radiographic features Plain radiograph. While it is not unusual for only a single AP film to be obtained, ideally, as with any trauma situation, two views are better than one. In most trauma situations, orthogonal views of the affected bone or joint. 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

There are two articles on the e-medicine website: 'Clavicle Fractures' in the orthopaedic section and 'Fractures, Clavicle' in the emergency medicine section. The former is extensive, well structured and includes the Allman classification, but is made up of large chunks of text which are more easily read printed out Neer made a significant revision to the Allman classification scheme. Group II (distal clavicle) fractures were further divided into 3 types, based on the location of the clavicle fracture in relation to the coracoclavicular ligaments visit www.orthofilms.com for more videos and infoAn animated description of the Allman classification system for clavicle fractures and a brief overview of s.. The Allman Classification of clavicle fractures separates the segments into thirds. Look for angulation and/or displacement of the fracture. Is it comminuted? If there is shortening, measure, and document the degree of overlap (> or < 2cm), sometimes best seen on a PA chest x-ray The Allman classification of clavicle fractures is the one most commonly used. It divides fractures based on anatomic region: Group 1: middle one-third. Group 2: lateral one-third. Group 3: medial one-third. Group 2 (lateral) was further classified by Neer, based on the relationship between the fracture line and the CC ligaments. This.

Fractures of the clavicle are typically described using the Allman classification system, dividing the clavicle into 3 groups based on location. Fractures of the middle third or midshaft fractures are in Group I (the most common), fractures of the distal or lateral third are in Group II, and fractures of the proximal or medial third are in. Craig Classification of Clavicle Fractures Group I - Fracture of the middle third Group II - Fracture of the distal third Type I - Minimal displacement (interligamentous In a prospective study, the age- and gender-specific incidence and features of clavicular fractures were studied during 1989 and 1990. The population at risk consisted of about 200,000 individuals aged 15 or above in the county of Uppsala, Sweden. There were 187 clavicular fractures in 185 patients tures. In the Allman classification, the clavicle is divided into 3 sections and numbered according to fracture incidence (mid-shaft I, lateral II, and medial III) (Allman 1967). This classi-fication gives little information regarding choice of treatment or expectations about outcome. In this article, we only discuss the Allman type 1 fractures

Classification Traditionally, treatment has been based on the following classification. Class A fractures involve the middle third of the bone and account for about 80% of clavicle fractures. The proximal fragment is often displaced upward because it is pulled by the sternocleidomastoid muscle Clavicle fractures can be classified into three groups, known as the Allman Classification, depending on the location and severity of the fracture: Group 1 Clavicle Fractures.

Clavicle Fracture: Symptoms, Diagnosis & Treatment

Introduction. Clavicle fractures are common injuries, accounting for around 3% of all fractures.They most commonly occur in adolescents and young adults, however a second peak in incidence also occurs over the age of 60, associated with the onset of osteoporosis.. Clavicular fractures can be classified by the Allman classification system, determined by the anatomical location of the fracture. Allman's Classification of Fracture Clavicle . This is an important theory topic which is usually asked as a short question in PG ( MS / DNB ) Orthopedics Exams 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. Group II - Lateral 1/3 Clavicle Fracture (10-15% FRACTURE CLASSIFICATION. Clavicle fractures are generally classified by their location . Allman has classified clavicle fractures based on three anatomic regions . 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 fractures: a comparison of five classification

  1. Classification of Clavicular Fractures There are multiple, documented classification systems that are used to categorize clavicle fractures. Allman was the first to propose categorizing clavicular fractures based on the location of the fracture 1,in 1967. 6,13 According to his system, fractures that occur in the middle third o
  2. Radiographs are used to identify the fracture site and characteristics. The Allman classification system divides the clavicle in to thirds (2,8): Group I. Midshaft Fractures: occurring in the middle third of the clavicle (75-80%) Group II. Distal Fractures: occurring in the lateral third of the clavicle (15-25%) Group III. Proximal Fractures.
  3. classification of clavicular fractures Distal clavicle fractures Type 1: coracoclavicular ligaments intact Type 2: coracoclavicular ligaments detached from the medial segment but trapezoid intact to distal segment Type 3: intra-articular extension into the acromioclavicular joint Robinson Neer Allman Crai
  4. CLAVICLE 1) Allman Classification 2) Neer's Classification of Allman Group II fractures (Lateral Third) NB: Neer in 1968 described only I to III. Rockwood created subsets of Type II - A and B.
  5. Two of the most popular include the Allman and Robinson classification systems. The Allman classification system divides the clavicle into 3 equal thirds (29). The Robinson classification divides the clavicle into fifths, but then joins the 3 central fifths into a uniform middle segment (30)

Midshaft clavicle fractures are common traumatic injuries seen in young adults that occur in the middle third of the clavicle. Diagnosis can be made radiographically with shoulder radiographs. Treatment is controversial but may be nonoperative or operative based on patient activity demands and the degree of radiographic displacement and shortening Middle 1/3rd clavicular fracture. Clavicle fractures are common accounting for 2- 4% of all adult fractures. They constitute 35% of the injuries to the shoulder. Most midshaft clavicle fractures will go on to heal uneventfully with non operative treatment Ossification and Clinical Features of the Human Clavicle. The human clavicle is considered to be a 'key' like structure and is said to be a long bone of the body although there are several differences from a classical long bone and the clavicle. It extends from the sternum in the front of the chest to the shoulder joint at its lateral end Clavicle fractures account for approximately 2.6 percent of all fractures [ 1,2 ]. The peak incidence occurs in children and young adults. Over one-third of clavicle fractures in males occur between the ages of 13 and 20 years, while 20 percent of clavicle fractures in women occur in the same age group [ 3 ]

AC joint dislocation: Tossy Classification Tossy et al, CORR, 28: 111-119, 1963 Grade 1: strain and contusions of AC joint; No deformity visible clinically or on x-ray Grade 2: localised pain, swelling and deformity; X-rays show one-half separation of the AC joint, ie clavicle displaced cephalad by one-half the depth of the AC joint; Coraco-clavicular distance increased as compared to normal. Several classification schemes have been suggested in the literature. Clavicle fractures are generally classified based on the location of the fracture (Allman, 1967, Robinson, 1998, Van Der Meijden et al., 2011).The Allman classification is the first one described and divides clavicle fractures into three groups (Allman, 1967): Group I, central third fractures (); Group II, distal third. The Neer classification for distal third (Allman group II) fractures is based on whether or not the coracoclavicular ligaments are intact (Fig. 15.6) . If they are intact, the fracture is at less risk for nonunion, but if torn, wider displacement is allowed and hence a higher risk of nonunion results All fractures were classified according to the Allman classification in which the clavicle is divided into thirds, group I fractures involve the middle clavicle third, group II include the lateral (distal) third whilst group III enclose fractures involving the medial (proximal) third . Statistical analysis was performed by means of Fisher's. FIGURE 10-4 The clavicle lies in close proximity to the neurovascular structures that supply the ipsilateral upper extremity.. Classification. In 1967 Allman 8 described 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%). The proximal and distal ends of the.

Since the 1960s, there have been a number of clavicle fracture classifications: Allman classification 25; Neer classification 26; Edinburgh classification, which was updated as Robinson classification 23; Craig classification 26; and OTA/AO classification. 27 Of these, the most widely used and accepted is the Allman classification Classification of clavicle fractures A number of classification systems have been proposed to aid in the description of clavicle fracture patterns for clinical and research purposes.1,12,40,43,52 To date, most modern clavicle fracture classification systems are primarily descriptive and not predictive of outcome. Th

A number of classification systems have been proposed for clavicle fractures.31, 2, 9, 21 The most commonly used is the Allman system, 2 which divides the clavicle into three groups based on the fracture location along the bone (group I middle third; group II in the outer or lateral third and group III in the inner or medial third) Allman classification : according to site of fracture : group 1: Fracture mostly occur in the middle one third of clavicle 80% . group 2: The fractures of outer third is 15% . Fractures involving the acromioclavicular joint 28% . group 3: fracture of inner [medial] third 5% Extreme proximal displaced Clavicle Fracture (Allman Group 3) Distal displaced Clavicle Fracture (Allman Group 2) Midshaft displaced Clavicle Fracture (Allman Group 1) indications.

Most common (approximately 80%) in both adults and children. [5] If displaced, the lateral fragment is usually pulled down by weight of limb and the medial fragment tends to be displaced upwards by the action of the sternocleidomastoid muscle

Classification. Clavicle fractures are first organized by their location on the bone. Middle third clavicle fractures are most common followed by the lateral third and then the medial third. There are several classification systems that can be utilized. Allman Classification. Group 1 = Middle third. Group 2 = Lateral third. Group 3 = Medial thir Several classification systems for distal clavicle fractures have been introduced. 7, 9, 10, 11) In 1967, Allman 11) suggested classification of clavicle fractures based on anatomic location, an approach that does not consider treatment approaches and/or prognosis. In 1994, Nordqvist et al. 7) further classified clavicle fractures based on displacement and comminution of the fracture

THE INJURY - CLAVICLE FRACTURE Clavicle fractures are categorized by location, known as the Allman classification [Allman] Group I - Consists of fractures of the middle third; Group II - Consists of fractures of the distal third (can be further subdivided into three separate types) Group III - Consists of fractures of the proximal third BACKGROUND. Fractures of the clavicle frequently occur, accounting for 2%-5% of all adult fractures; over two-thirds of clavicle fractures occur within the middle third. 1,2 Allman described the first widely used classification system of clavicular fractures in 1967 based on the location of the fracture site. 3 In 1998, this classification was modified by Robinson emphasizing the presence of. Descriptive Classification. Clavicle fractures may be classified according to anatomic description, including location, displacement, angulation, pattern (i.e., greenstick, oblique, transverse), and comminution. Allman Classification. Group I: fracture of the middle third (80%). Most common fracture in both children and adults; proximal and.

A clavicle fracture will often cause instant pain in the shoulder or collarbone. Other broken collarbone symptoms include: Swelling. Deformity. Limited range of motion in your arm. Broken collarbone diagnosis. Your doctor will look for signs of a fracture — such as a lump or bump — on the clavicle, or collarbone The Allman classification system divides the fractures by location, displacement, and level of comminution. A Group 1 fracture is of the middle third of the clavicle with the ends still secured by the ligaments. A Group 2 fracture is of the distal third. There are three major types of Group 2 fractures These fractures have been classified by Allman into groups I (mid-shaft), II (lateral), and III (medial); this classification, along with fracture characteristics (eg, displacement and comminution) is used to assist with determining the strategy for management. AB - Clavicle fractures are common, and it is important for primary care.

clavicle fractures. Medial third fractures are least common, accounting for less than 5 percent of clavicle fractures. Figure 1: Allman classification, according to anatomical site. Clinical Anatomy: The anatomy of the clavicle is shown in (Figure 2). The clavicle is easily fractured because o Patients with closed midshaft fracture clavicle (type-1, according to Allman classification system) of less than three weeks duration are included in the study. Those with open fracture, more than three weeks duration, paediatric and geriatric age group, pathological fracture, clavicle fracture associated with other fracture of th PHF are considered non-displaced if no segment is displaced more than 1 cm or angulated more than 45 degrees, while displaced fractures are classified according to the number of displaced fragments. 6 The anatomic site of clavicle fractures are typically described using the Allman classification, which divides the clavicle into thirds (proximal. The classification of clavicle fractures is complex and is determined first by the location of the fracture within the clavicle (group I, midshaft; group II, distal third; group III, proximal third) per the Allman and Neer classification. 14 Group I (midshaft) fractures are the most common and account for 80% of clavicle fractures.
