The Comprehensive Classification of Fractures of Long Bones

Implant Material and Design Alter Construct Stiffness in Distal Femur Locking Plate Fixation: A Pilot Study

“…However, none of our BICs reached 100,000 cycles and/or forces of 1870 N, which is considered as a loading regimen simulating physiologic forces over a 2-month period [5]. Our fracture model represents an extraarticular fracture, which is classified as a type of distal femur fracture [15] associated with substantial complication rates [16]. This model is used in multiple biomechanical studies [5,11,14,21,25].…”

“…An extraarticular distal femur fracture type, AO/OTA 33-A3 [15], was simulated using artificial bone substitutes and a 25-mm defect zone (Fig. 1).…”

Classifications in Brief: Lauge-Hansen Classification of Ankle Fractures

“…Like the Danis-Weber classification, it is based only on radiographic criteria, in contrast to the Lauge-Hansen system, which unlike all other appendicular fracture classification systems, incorporates the mechanism of injury. In the AO/OTA classification, ankle fractures are classified as infrasyndesmotic (correlating to Danis-Weber Type A injuries), transsyndesmotic (correlating to Danis-Weber Type B injuries) or suprasyndesmotic (correlating to Danis-Weber Type C injuries) with further subsets based on presence or absence of medial or posterior malleolar injuries [18]. This is in contrast to the Danis-Weber classification that completely ignores the medial and posterior structures.…”

Non-union coronal fracture femoral condyle, sandwich technique : A case report

“…A subsequent report from lewis et al 4 failed to validate this classification. The AO comprehensive classification of long bone fracture and OTA fracture compendium identify the unicondylar coronal fracture but provide little information about prognosis or treatment 12,13 .…”
