Supination

Definition and stakes

Auguste Broca,  Artificial Limbs

“ Appliances with Mobile Joints.—In the course of work the direction of the wrist is changing at every instant, flexion, extension, pronation, and supination occurring, sometimes in order to move around the object, sometimes in order to maintain a suitable position when the movements of the shoulder and elbow vary the direction of the forearm.
The consequence of this is that the worker learns to turn the piece of work around with his sound hand.

Alexander Miles,  Manual of Surgery Volume Second…

“ In some cases the callus fuses the two bones across the interosseous space, and pronation and supination are rendered impossible.
Persistent angular deformity of the forearm is also liable to ensue, either from failure to correct the displacement primarily, or from subsequent bending due to ill-applied splints or slings. Want of union, or the formation of a false joint in one or both bones, is sometimes met with, particularly in children, and, like the corresponding fracture of the leg, is liable to prove intractable.

Berkeley Hill,  The essentials of bandaging (1869)

“ The splints and rollers should be removed on the fourth or fifth day, that the positions of the fragments may be examined and the roller again applied to draw them closer together. After ten or twelve days, passive motion of the wrist and fingers, with pronation and supination of the radius, should be adopted, but great care is to be taken that the patient does not inadvertently bend the elbow joint while free of the splint. The splint must be worn, with the frequent removals directed above, for five weeks, by which time gentle flexion of the elbow may be practised. ”
