The principles of fracture classification • Generally, proximal and distal segments are defined by a square whose sides = length of widest part of epiphysis • Exceptions: - Proximal femur - Proximal humerus - Malleolar segment 12.

association of AO fracture types in distal radius fractures with DASH score have been tabulated and projected in a bar diagram (Tables 1 & 2). Table 1: AO classification of distal radius fractures with subtypes. 23A – Extra-articular Fracture A1 – Extra-articular fracture of the ulna, radius integral

After 3 months the injuries were again classified with the addition of the clinical findings of each patient and the level of agreement evaluated. cervical spine fracture classification systems. AO classification of upper cervical injuries; AO classification of subaxial injuries; Anderson and D'Alonzo classification (odontoid fracture) Roy-Camille classification (odontoid process fracture) Levine and Edwards classification (hangman fracture) AO/OTA classification. Widely used system that includes 27 subgroups.

Fig 2.2-1 Müller AO/OTA Classification for numbering the anatomical location of a fracture in three bone segments (proximal = 1, diaphyseal = 2, distal = 3). F1: AO/OTA type-31-A pertrochanteric fractures. 31-A1 fractures are simple, whereas 31-A2 fractures are multifragmentary. Subgroups of 31-A2 pertrochanteric fractures are A2.1 (detachment of the lesser trochanter), A2.2 (several intermediate fragments including detachment of the lesser trochanter), and A2.3 (several intermediate fragments extending more than 1 cm distal to the lesser Fractures about or in a bone with a nonarthroplasty implant are coded using the universal modifier [12] following the AO/OTA fracture code.

Read more AO Surgery Reference The AO group has developed a comprehensive classification of fractures. This classification is arranged in order of increasing severity according to the complexities of the fracture, difficulty of treatment, and worsening prognosis. Figures.

Minor, nonstructural fractures Compression fracture involving a single endplate without involvement of the posterior wall of the vertebral body. Wedge-compression Coronal split or pincer fracture involving both endplates isolated diaphyseal fracture of the ulna). When the paired bones radius/ulna or tibia/fibula are fractured with different child patterns (eg, a complete fracture of the radius and a bowing fracture of the ulna), each bone must be coded separately, including the corresponding small letter (22r-D/5.1 & 22u-D/1.1).

Widely used system that includes 27 subgroups. Three main groups based on fracture joint involvement (A - extra-articular, B - partial articular, C - complete articular). Classification further defined based on level of comminution and direction of displacement. Fig 2.2-1 Müller AO/OTA Classification for numbering the anatomical location of a fracture in three bone segments (proximal = 1, diaphyseal = 2, distal = 3). A wedge fracture has a center which is the broadest portion of the wedge or the mid portion of the fragmented area when reduced.

Coding—bone and location Alphanumeric structure of the AO/OTA classification The anatomical location of the fracture is designated by two numbers: one for the bone and one for its segment. The tibia is an exception with the malleoli representing a fourth segment (44). 2018-07-12 The AO Spine Thoracolumbar and Subaxial Injury Classification systems are the result of a systematic assessment and revision of the Magerl classification.

Distal Humerus and Elbow Joint The compendium is branded as the AO/OTA or OTA/AO Fracture and Dislocation Classification Compendium. In publications, it will be cited as Meinberg E, Agel J, Roberts C, et al. Fracture and Dislocation Classification Compendium–2018, Journal of Orthopaedic Trauma. Volume 32: Number 1; Supplement, January 2018. In 1996, the AO Foundation and the Orthopaedic Trauma Association agreed to develop a Fracture Classification Compendium encompassing all appendicular bones, pelvis, and spine based on the principles and definitions of the Müller system [12, 13].

In a graphical scheme of the skull, diagrammatic recording of the fracture pattern in the midface, orbits, skull base, and cranial vault is done by checking criteria in the appropriate subdivision. AO Surgery Reference is a resource for the management of fractures, based on current clinical principles, practices and available evidence. AO Principles of Fracture Management is an essential resource for orthopedic trauma surgeons and residents in these specialties.
