In this study we will discuss entrapment of the median, ulnair, radial and lateral antebrachial nerves of the elbow and the forearm. Compression of the nerves may occur when they traverse a tunnel and an incompatibility exists between the diameter of the tunnel and its contents (e.g. nerves, tendons,...). ⋯ This is due to anatomical relationships changing between the nerve and its surrounding muscles, tendons and aponevroses during the motion of flexion-extension of the elbow and the prono-supination of the forearm. The possibility of this dynamic factor should be thoroughly explored during the examination through appropriate dynamic tests as described in this study.
