The AO group has developed a comprehensive classification of . Table 1: Distal femur AO classification. These include displaced fragments of the dorsoulnar corner type C1.2 and C2.1 according to the AO classification of distal radius fractures,15 irreducible intra-articular or extended extra-/intra-articular dorsal comminution that cannot be reduced by ligamentotaxis only or difficult to access/address from palmar (ie, AO B2/C3, die punch, type . The treatment of distal femur fractures has long been a controversial topic. Distal femur fractures include fractures of the supracondylar and intercondylar region and are relatively common injuries. approach was predominant. Femoral shaft fractures can be classified with the Winquist classification or the AO/OTA classification. Complex fractures. 1. humerus 2. radius/ulna 3. femur 4. tibia/fibula - which segment? Explanation. Fracture of the petrous temporal bone is usually classified according to the main orientation of the fracture plane and/or involvement of the otic capsule.. Fracture orientation. AO/OTA classification of proximal femur fracture AO/OTA classification of proximal femur fractures. They account for around 3-6% of femur fractures.They occur both in younger patients (as the result of high energy trauma) or in older patients (from low energy trauma as a pathological fracture secondary to osteoporosis or . AO Surgery Reference—Dog. (1967), 2) Seinsheimer classification (1980), and 3) the Müller AO Classification (1990) [4-6]. Classification. According to the Müller AO classification of distal femur fractures (33A-C) there were 15 cases with extra-articular fractures (AO 33A), 5 patients with intra-articular fractures (AO 33C).

The most common subclassification was Rorabeck type II, with 363 fractures. Proper anatomical reduction of articular surface and rigid fixation is required, if The 2018 revision addresses the many suggestions to improve the application of the system and includes recently published and validated classifications. General Principles. 1 - Humerus 2 - Radius/Ulna 3 - Femur 4 - Tibia/Fibula-1,2,3 = Proximal, diaphysis, distal. 2R3 Distal end segment 9 AO/OTA Fracture and Dislocation Classification Long-bone Fractures 10 11 >30 . Abstract. Although there are several classification systems, a descriptive classification is the most useful and includes fracture location (proximal, middle, or distal), pattern (simple, wedge butterfly, or comminuted), and whether the fracture is open or closed. Frykman, G. (1967). Distal femoral fracture contributes to 6% of femoral fracture [3] and 29% of non-proximal femoral fractures [4]. - Due to trapezoidal shape of the distal femur • Erroneous plate placement can cause malreduction . The treatment of distal femoral It has been adopted by OTA, also known as AO/OTA classification. Distal femur fractures are traumatic injuries involving the region extending from the distal metaphyseal-diaphyseal junction to the articular surface of the femoral condyles. Introduction. The optimal AP view of the distal femur is obtained when: the patella is centered over the femoral notch. The AO/OTA Fracture and Dislocation Classification Compendium is now available for free download. Comminuted, with any combination of the above. Comminuted, with any combination of the above. Majority (70%) of the patients were males between the ages of 17 to 70 years and 68% sustained other injuries too. 3. 39. Scholars at home and abroad have proposed a variety of classification systems. Femur 3 31 Proximal end segment 32 Diaphyseal segment 33 Distal end segment Partial articular, coronal plane fractures of the posterior part of femoral condyles are called Hoffa fractures. 2. Keywords: AO type C distal femur fracture, distal femur locking plate, NEER knee score Introduction Distal femur fractures remain challenging injuries both for the surgeon to treat and for the patient to get full recovery to reach pre-injury state. Type A fracture of the distal femur are extraarticular, these fractures do not involve the articular surface but may be within the capsule of the joint. the distal femur is centered on the screen. 4A. The goals of treatment follow AO principles of anatomic reduction of the articular surface, restoration of limb alignment, length, and rotation. Open reduction and internal fixation was carried out in 60 . Involves patellofemoral articular surface, but not the femorotibial articular surface. Metaphyseal FractureS Tibia. The average patients' age was 41.2 years (18-64 years). The number of fractures showed a bimodal pattern with a marked variation in the number of fractures in relation to gender and age.

According to the AO classification, 15 patients with type 33A, 4 patients with type 33C, 13 patients with type 32A and 2 patients with type 32B and 3 patients with type 32C . Galeazzi fracture-dislocations consist of a fracture of the distal part of the radius with dislocation of the distal radioulnar joint and an intact ulna. Alphanumeric structure of the Müller AO Classification of Fractures—Long Bones for adults 11-13-12-21-23-22-31-33-32-41-43-42-44-Example 32-B2 3 femur 2 diaphyseal B wedge fracture 2 . The AO- coding of fractures is an alpha- numeric system, which describes the location of the fracture with first two numbers, followed by a letter and two numbers, which describe the morphological characteristic of the fracture: Location: The first number describes the bone (see the next image), for example: 1- Humerus 2- Radius/ Ulna 3- Femur . The AO classification was born when Müller et al. 4 In this classification the first number refers to the femur (3), the second number refers to the location within the femur (3) and the letters A, B and C refer to . During the past decades the term "supracondylar" has included fractures of the distal 15 cm, the distal 9 cm and the distal 7.5 cm [3-6]. Diagnosis is made radiographically with radiographs of the femur as well as the hip to rule out ipsilateral femoral neck fractures. Open subtypes (3) Proximal 1/3. CT-scans: Highly recommended with high energy trauma and if an intra-articular fracture is suspected. 41. Open subtypes (2) C2.1/.2 Simple articular, wedge metaphyseal. Classification. Middle 1/3. In 1963, AO introduced the fixed angled plate for the treatment of distal femur fractures and reported 73.5% of good or excellent results in 112 pa-tients. Inclusion criteria 1.

Moreover the AO clas-sification unanimously has gained acceptance for distal femoral fractures. Consistency of AO fracture classification for the distal radius. Learn more Choose fracture. The study included 20 patients with 20 fractures (13 males, 7 females). Management of AO type C3 distal femur fractures with multifragmentary articular involvement is challenging, with most series reporting average to poor results and frequent complications such as malunion, knee stiffness, and secondary osteoarthritis. 4B. Distal femur fractures are fractures extending from the distal metaphyseal-diaphyseal junction of the femur to the articular surface of the femoral condyles.. Fracture of the distal femur may be broadly classified as extra-articular, intra-articular unicondylar, or intra-articular bicondylar, with subclassifi-cations for specific patterns and de-grees of comminution. On this page: Management of AO type C3 distal femur fractures with multifragmentary articular involvement is challenging, with most series reporting average to poor results and frequent complications such as malunion, knee stiffness, and secondary osteoarthritis. MULLER AO CLASSIFICATION. The commonest cause of injury was simple mechanical fall. 4A. The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. Clinical features. for distal femur fractures: 1) Neer et al. (1967), 2) Seinsheimer classification (1980), and 3) the Müller AO Classification (1990) . 1. humerus 2. radius/ulna 3. femur 4. tibia/fibula - which segment? Intertrochanteric Neck and head hip fractures fractures Examples of treatment 31-A with DHS 31-B and C with hemiarthroplasty We will further discuss the 31-A fractures. The more commonly used types are Seinsheimer type and AO type. distal segments of long bones are defined by a square the sides of which have the same length as the widest part of the epiphysis (exceptions 31- and 44-). The AO classification divides the distal femoral fractures into three groups, A, B and C with complexity and severity increasing 1. type A: extraarticular. Medial condyle, extending to the femorotibial articular surface. 4C. C2 Simple articular, wedge or multifragmentary metaphyseal. Intact segmental. Lower Extremity Functional Scale [7,8] defined supracondylar-intercondylar lesions as fractures whose center lies within a square of which the side length is determined by the width of .

Patients were classified into AO classification of distal femur fractures. The AO classification of distal femoral fractures is one of the commonly used fracture classification systems in orthopedics. 42. In one study on supracondylar intercondylar fractures of distal femur, 38% had a coronal fracture. 1,2,3,4,5,6,7,8,9,10,11 Only a few studies 1,2,3,4,5,6 have exclusively reported the outcome of complex C3 type fractures of the . * To code the diagnosis of fracture, one must know its location and its morphology Location * This is designated by two numbers - which bone? The most common classification system used for distal femur fractures is the AO/OTA system. It has been adopted by OTA, also known as AO/OTA classification. Femoral shaft fractures and distal femoral fractures may occur in young due to high energy trauma or elderly due to low energy trauma. CMF, proximal femur, distal femur, patella, tibial shaft (members only) Femoral shaft (free module) Access all dog modules here. Despite improvements in implant design, management of distal femur fractures remains a challenge; fractures are often comminuted . Classification and coding process. The AO classification of distal femoral fractures. Η αντιμετώπιση . A total of three classification systems have been mainly proposed for distal femur fractures: 1) Neer et al. * To code the diagnosis of fracture, one must know its location and its morphology Location * This is designated by two numbers - which bone? Distal femur fractures are designated as "33". Femoral shaft fractures are usually clinically obvious due to local . 69 reported a Clinical Results in 103 fractures. Femoral shaft fractures are high energy injuries to the femur that are associated with life-threatening injuries (pulmonary, cerebral) and ipsilateral femoral neck fractures. There are many types of distal femoral fracture. The 2nd half pin was applied proximal to the The AO classification of distal femoral fractures. Towards 1950-1960 the conservative . The AO/OTA fracture classification system is the most universally used4 (Figure 1). Introduction: Fractures of the distal femur account for 0.4% of all fractures. Clinical assessment was conducted at least 6 months post-operatively using the . Neer et al. Fractures were classified by AO classification; most of them were intrarticular CI type. General principles of ortho trauma for PA students 1 - The AO/OTA classification of distal humeral fractures is one of the most frequently used systems for classifying distal humeral fractures. Learn more Choose fracture. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the predecessor of the AO Foundation. Temporal bone fracture is described relative to the long axis of the petrous temporal bone, which runs obliquely from the petrous apex posterolaterally through the mastoid air cells. These fractures are classified according to the AO/ASIF classification or Winquist-Hansen classification.
