The posterior aspect of the elbow is studied with the elbow flexed at 90° with the palm resting on the table (Fig. 3.14c). Proximal to the olecranon, the triceps muscle and tendon should be evaluated in long and short axes (Fig. 3.15a). Located deep to the triceps, the olecranon fossa and posterior recess should also be examined. To study the cubital tunnel, the probe is placed parallel to the olecranon and the medial epicondyle, and the ulnar nerve is examined from the distal arm through the forearm in transverse sections. Dynamic evaluation should be performed to detect the presence of intra-articular fluid or nerve instability [20].

Extreme flexion of the elbow is associated with cubital tunnel syndrome (Bora and Osterman 1982, Feldman et al. 1983, MacNicol 1982, Spanns 1970, Wadsworth and Williams 1973). This posture (see Figure 1 (c)) is often associated with assembly and inspection of small parts that must be held close to the eyes. Extreme rotation of the forearm is associated with medial and lateral epicondylitis (Goldic 1964. Hoffman 1981, Kurppa et al. 1979, Tichaucr 1976). Examples of these postures (sec Figure 1 (J) and (e)) arc often seen in workers holding parts and materials in front of their bodies.

A cumulative trauma disorder is a breakdown of a body part as a result of repetitive overuse, overexertion, or excessive stress. Examples of conditions that can be referred to as cumulative trauma disorders are: BursitisCarpal tunnel syndromeCubital tunnel syndromeDeQuervain’s diseaseDigital neuritisEpicondylitisExcessive fatigueFrozen shoulderGamekeeper’s thumbGanglion cystGuyon canal syndromeHypothenar hammer syndromePeritendonitis crepitansPronatoi teres syndromeRadial tunnel syndromeRaynaud’s phenomenaStenosing tenosynovitisStenosing tenosynovitis crepitansSynovitisSupinator syndromeTendonitisTenosynovitisThoracic outlet syndrome

According to hospital examinations, both groups reported multiple dominant arm syndromes (pain, sore muscles and numbness), with the expert group members exhibiting cubital tunnel syndrome (58.33%), carpal tunnel syndrome (33.33%) and tendinopathy of the extensor tendon (25%) and the non-expert group members exhibiting tendinopathy of the extensor tendon (100%), osteoarthritis (63.64%), carpal tunnel syndrome (54.55%), radiculopathy (45.45%), cubital tunnel syndrome (36.36%), tendinopathy of the flexor tendon (36.36%), calcifications (36.36%) and ligament injury (36.36%).
