This document discusses several hand disorders and conditions, including ulnar nerve injuries, Dupuytren's contracture, and Volkmann's ischemic contracture. It notes the anatomical structures involved in ulnar nerve injuries, such as the ulnar nerve, medial epicondyle, and flexor carpi ulnaris arcade. Dupuytren's contracture involves thickening of the palmar aponeurosis. Volkmann's ischemic contracture can result from a supracondylar humeral fracture causing reduced blood flow to the forearm muscles.
