Bony lesions were created experimentally in 48 fresh cadaver wrists. They consisted of radial and scaphoid resections along the extent of the proximal carpal row, representative of clinically-induced (usually traumatic) lesions. The displacements obtained experimentally to mirror each clinical situation modify the physiologic equilibrium established between the trans-osseous forces and the ligaments. The comparison between the experimentally-induced lesions and clinical displacements shows the etiology of the clinical conditions which indicates the proper treatment.
