Reduction, however, can be made more difficult by different blocks to reduction, such as impaction of the ulnar head [1, 3, 6-8], spasm of the
pronator quadratus [5, 22], and interposition of the torn TFCC [4].
We used a four-channel EMG device (ME3000P8 muscle tester, Mega Electronics Ltd, Finland) for recording simultaneously four muscle groups; extensor carpi radialis, palmaris longus,
pronator quadratus, flexor digitorum superficialis.
Soft-tissue differentials included a mild sprain of the ulnar collateral and annular ligaments, and strains of the
pronator teres, biceps, brachialis, and elbow extensor group.
What's more, power assessment of the
pronator teres, flexor carpi radialis, and flexor digitorum superficialis may exacerbate symptoms.
El pronador cuadrado (
Pronator quadratus) se origina en el margen caudal del tercio distal de la ulna y se inserta en el margen caudal del tercio distal del radio en C.
El musculo pronador teres (
pronator teres) se inicio por dos ramas, una en el epicondilo medial y ligamento colateral y otra en proximal de la fosa coronoidea del humero, insertandose por un tendon aplanado en la cara dorsal del radio (Figura 8).
Variations in its number of branches to
pronator teres are frequently seen.
He was diagnosed with an ulnar collateral ligament tear and a flexor
pronator tear.
Superficial fascia belonging to the flexor
pronator muscle group was elevated as a broad fascia flap with a width exceeding approximately 3 cm and a position of 1-2 cm apart from the medical epicondyle origin.
The
pronator quadratus muscle is raised from lateral border of the radius and lie in a horizontal position carefully.
If the history and physical exam suggest a scaphoid fracture, the initial imaging studies should include plain radiographs in the conventional manner (anteroposterior, lateral, and oblique views), along with three specialized views (posteroanterior in ulnar deviation,
pronator oblique, and supinated oblique) which increase the sensitivity of finding an acute scaphoid fracture.
Las masas pueden afectar un solo miembro, o bien, ser bilaterales (17, 18) y pueden encontrarse adheridas a la capsula articular del codo (15) o en los tendones de los musculos flexores del codo, como el musculo flexor digitalis profundus (13), musculo flexor digitalis superficialis (6, 13, 15), musculo flexor carpi ulnaris (18), musculo flexor carpi radialis (17, 18) o musculo
pronator teres (13, 17)
