Cohera Symptom

The Kocher-Schmorl symptom is a paradoxical fracture (symptom), which is described as two-stage and non-articular; occurs with a sharp dorsal extension of the forearm outward in the area of ​​the anatomical snuffbox (proximal and supinator), and when pressing on the anterior part of the forearm, a click occurs. Simultaneously with this movement, pain may occur or intensify at the top of the greater tuberosity of the wrist (Beauregard). A similar fracture sometimes occurs when the head of the 5th metacarpal bone is flexed at the intermetacarpal joint. With diaphyseal fractures of the metacarpal bones, mismatch of fragments is sometimes noted. The fracture is often accompanied by median nerve neuropathy.
