Imal humeral fractures, while the AO type C fractures occur in only 6% We suggest that the literature does not adequately re' ect the spectrum of proximal humeral fractures n Proximal humeral fractures are relatively common, as they represent about 4% of all fractures seen in the average orthopaedic clinic (Horak and Nilsson 1975) Nevertheless, little is known about theirOpen fractures, Infection, Compartment syndrome 3;The fracture will be reduced closed, thus indirectly In some cases, a fracture table may be used eg, fracture of the proximal femur, tibia shaft (less common), etc An external large distractor may help to achieve the reduction process in a gentle and controlled process

A proximal humerus fracture
A proximal humerus fracture- Proximal fractures of the humerus showed a seasonal variation in frequency The fact that there were more fractures during the winter months can probably be explained by the increased occurrence of simple falls due to the icy conditions in Gothenburg during the winter CourtBrown et al reported a similar finding in Scotland and they revealed that patients The AO classification of proximal humeral fractures, along with the Neer classification, is one of the most frequently used systems for classifying proximal humeral fractures The AO classification divides proximal humeral fractures into three groups, A, B and C, each with subgroups, and places more emphasis on the blood supply to the articular surface 1,2

Based on AO classification, the proximal end of the humerus is delineated by a square with its lateral side equal to the maximum width of the epiphysis The AO coding of a proximal humerus fracture is " 1 1," and is further divided into three categories based on the severity of injury types A, B, and CIn fractures with markedly displaced proximal, metaphyseal fragmentation it is crucial to still achieve anatomic or almost anatomic reduction The older the patient, the more important this is, to prevent nonunion and regain optimal function To achieve this, the plate should provide sufficient fixation points in the proximal humerus/humeral head It also should be long enough Typically, The reporting and interpretation of data from clinical trials of proximal humeral fractures are hampered by the use of two partly incommensurable fracture classification systems the Neer classification and the AO/OTA classification It remains difficult to interpret and generalize results, to conduct prognostic studies, and to obtain consensus on treatment recommendations
