Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
Linburg–Comstock variation is an occasional tendinous connection between the flexor pollicis longus and the flexor digitorum profundus of the index, the middle finger or both. It is found in around 21% of the population. [ 1 ]
Cheiralgia paraesthetica (Wartenberg's syndrome) is a neuropathy of the hand generally caused by compression or trauma to the superficial branch of the radial nerve. [1] [2] The area affected is typically on the back or side of the hand at the base of the thumb, near the anatomical snuffbox, but may extend up the back of the thumb and index finger and across the back of the hand.
The main symptoms are pain in the hand, numbness, and tingling in the thumb, index finger, middle finger and the thumb side of the ring finger. [1] Symptoms are typically most troublesome at night. [2] Many people sleep with their wrists bent, and the ensuing symptoms may lead to awakening. [7]
More specifically, the patient's index and middle finger cannot flex at the MCP joint, while the thumb usually is unable to oppose. This is known as hand of benediction or Pope's blessing hand. Another test is the bottle sign—the patient is unable to close all their fingers around a cylindrical object. [10]
Compression of the median nerve in the region of the elbow or proximal part of the forearm can cause pain and/or numbness in the distribution of the distal median nerve, and weakness of the muscles innervated by the anterior interosseous nerve: the flexor pollicis longus ("FPL"), the flexor digitorum profundus of the index finger ("FDP IF"), and the pronator quadratus ("PQ").
As might be expected, the symptoms involve weakness in the muscle innervated by the AIN including the flexor digitorum profundus muscle to the index (and sometimes the middle) finger, the flexor pollicis longus muscle to the thumb and the pronator quadratus of the distal forearm.
Froment sign is the flexion of the interphalangeal joint of the thumb rather than adduction of the entire thumb. Note that the flexor pollicis longus is nearly always innervated by the anterior interosseous branch of the median nerve. Simultaneous hyperextension of the thumb MCP joint is indicative of ulnar nerve compromise. This is also known ...
