OBJECTIVE To compare the detailed architectural properties of the pronator teres (PT), extensor carpi radialis brevis (ECRB), and extensor pollicis longus (EPL) muscles to evaluate the suitability of PT-to-ECRB and PT-to-EPL surgical procedures. METHODS Muscle physiologic cross-sectional areas and region-specific muscle fiber lengths were measured in cadaveric PT, ECRB, and EPL muscles (n = 1...

OBJECTIVE To assess the anatomical variations of the pronator teres muscle (PTM) and its implication in the compression of the median nerve, which passes through the humeral and ulnar heads of the PTM. METHODS For the present study, 100 upper limbs from human cadavers from the anatomy laboratory were dissected. Forty-six specimens were male and four, female, whose aged ranged from 28 to 77 ye...

OBJECTIVE To investigate muscle activities during locking-unlocking movements. METHODS Thirty right-handed healthy volunteers, aged between 18-23 years, without any orthopedic or neurological disorders participated in the study. We choose the clavicular part of the deltoid muscle, biceps brachii, pronator teres, extensor digitorum, pronator quadratus, first dorsal interosseous muscles and mus...

Details of a 23 year old patient who suffered the spontaneous onset of an anterior interosseous nerve palsy are recorded together with the results of a full neurophysiological investigation. Isolated lesions of the anterior interosseous nerve are rare and there are no recorded cases with comprehensive neurophysiological investigation. The anterior interosseous nerve is a purely motor nerve and ...

To position the volar plate on the distal radius fracture site, the pronator quadratus muscle needs to be detached from its distal and radial side and lifted for optimal exposure to the fracture site. Although the conventional approach involves repair of the pronator quadratus, controversy surrounds the merits of this repair. The purpose of this study was to compare the functional outcomes of p...

BACKGROUND The angle-dependent torque capacity of the subtalar pronators and supinators is important to maintain dynamic ankle stabilisation. Based on the peak torques during maximum voluntary isometric pronation and supination across the subtalar range of motion, the strength curves of younger and elderly males and females were investigated. METHODS Maximum voluntary isometric subtalar prona...

BACKGROUND Due to the specific anatomy of the subtalar joint with its oblique axis, isometric pronator and supinator strength is not well documented. The purpose of this study was to determine intra- and between-session reliability of pronator and supinator strength and lower leg muscle activity measurements during maximum voluntary isometric contractions (MVIC). METHODS Pronator and supinato...
