case_images: Isolation of the deep motor branch of the ulnar nerve prior to decompression. The separate compartment of the deep motor branch within the substance of the transverse carpal ligament can be seen. (A) The deep motor branch can be seen entering the compartment within the transverse carpal ligament. (B) the tenotomy scissors can be seen in the separate canal, alongside the deep motor branch, prior to complete release. (C) The compartment is demonstrated after mobilization of the deep motor branch.
