- •The study analyzed the strain of the brachialis muscle by using strain gauges.
- •A strain of the brachialis muscle was observed under varus forces with a pronated forearm.
- •The strain increased significantly in case of a ruptured ulnar and lateral collateral ligament.
- •A concomitant tear of the brachialis muscle may result in pronounced instability.
