DeQuervain's tenosynovitis is a common cause of radial-sided wrist pain. Symptoms result from a narrow first dorsal compartment and associated tendinosis of the enclosed extensor pollicis brevis and/or abductor pollicis longus (APL). Surgical intervention, offered when conservative measures fail to adequately relieve symptoms, requires a detailed understanding of potentially aberrant anatomy in order to avoid persistence or recurrence of symptoms.

Parsonage-Turner syndrome (PTS) is a rare neuropathy that commonly presents as unexpected severe shoulder and arm pain that eventually subsides while weakness or paralysis ensues. During exceptions to this classic presentation, confirming PTS can be challenging. Alternative causes of upper extremity pain may confound the diagnostic algorithm. Moreover, objective findings from necessary diagnostic tests depend on when those tests are performed.
