IMPORTANCE Excessive use of smartphones has been associated with injuries. OBSERVATIONS A 29-year-old, right hand-dominant man presented with chronic left thumb pain and loss of active motion from playing a Match-3 puzzle video game on his smartphone all day for 6 to 8 weeks. On physical examination, the left extensor pollicis longus tendon was not palpable, and no tendon motion was noted wit...

BACKGROUND In the compromised nutritional status, there is excessive skeletal muscle loss and decreased inflammatory response, contributing to increased morbidity and mortality and length of stay. AIM To estimate the prevalence of malnutrition by measuring adductor pollicis muscle using cutoffs for surgical patients suggested in the literature. METHODS Cross-sectional study with 151 patient...

DESCRIPTION A 35-year-old man suffered a self-inflicted work injury from a circular saw on the dorsum of the thumb on his nondominant hand, sustaining a total transection of his extensor pollicus longus (EPL) and a concomitant dorsal capsule injury.

One cm longitudinal incision was made on the radius styloid process. Dissection of soft tissue was performed with taking care of extensor pollicis brevis, abductor pollicis longus and superficial branch of radial nerve. Guide wire was inserted from tip of the radius styloid process. After surgeon recognized no displacement in fluoroscopy, break-away screw (Acutwist®, Nihon Medical Next, Osaka, ...

We characterize a mechanism of injury, injury pattern, and treatment algorithm for adductor pollicis myotendinous injuries in 2 professional baseball players. Similar to myotendinous eccentric injuries in other anatomical areas, the adductor pollicis sustains a sudden forceful eccentric load during a jammed swing, resulting in intramuscular strain or tendon rupture. Based on the reported injury...

The clinical and electrophysiological picture of seven patients with the pronator syndrome is contrasted with other causes of median nerve neuropathy. In general, these patients have tenderness over the pronator teres and weakness of flexor pollicis longus as well as abductor pollicis brevis. Conduction velocity of the median nerve in the proximal forearm is usually slow but the distal latency ...

Thenar pain can represent a significant morbidity for a baseball player who relies on manual dexterity for gripping a bat and precise and accurate throws. While osseous, ligamentous, and neurovascular pathologies are commonly considered, musculotendinous injuries are often neglected in the differential diagnosis of thenar pain. We present a case of adductor pollicis longus strain as a cause of ...
