SOMSO skeleton model of hand with part of the forearm bones mounted on elastics

Anatomically, the model shows all the bones of the hand, as well as the lower part of the coil bone (radius) and the elbow bone (ulna).



The model only illustrates bone parts and the many joints of the hand and forearm, ligaments are not included. As the bones are rendered realistically, many osseous landmarks are clearly visible.

In terms of movement, the individual bone parts are held together by elastic bands. The carpal bones can therefore be pulled apart easily, just as there is free movement in all joints.

Clinically, this model is ideal for understanding fractures such as Colle's fracture (but also Smith's and Barton's fractures). It can also be used to understand scaphoid fractures and other fractures in the hand.



Furthermore, the model can be used to understand joint slippage (luxation), arthrosis (wear-and-tear arthritis) and possibly rheumatoid arthritis, although neither joint capsules nor clear markings of cartilage are seen on joint surfaces.
