“…5,7,16,26,27,59,60 Other causes include partial damage to the median nerve in the antecubital fossa during catheterization of the brachial artery or clumsy venipuncture, 12,33,80 and partial median nerve entrapment by an accessory bicipital aponeurosis. 61 The likely explanation for these pseudoanterior interosseous neuropathies is that the damage is restricted to certain fascicles: at this level, the motor fibers destined for the anterior interosseous nerve lie posteriorly in the nerve and bear the brunt of the injury from the fractured bone (Fig.…”

Peripheral nerve fascicles: Anatomy and clinical relevance

Within a peripheral nerve, the individual nerve fibers are grouped together in fascicles. Whether there is somatotopic organization within these fascicles has long been of interest, the subject of many investigations, and somewhat controversial. Evidence from diverse sources now points to important somatotopic clustering of nerve fibers within most of the length of the nerve. Information is lacking regarding proximal segments, particularly the plexus and spinal nerve root levels. As a result of this somatotopic arrangement, partial focal nerve lesions can produce restricted clinical deficits that defy the classic rules of localization. Examples of such restricted nerve lesions are provided in this review. Recognition of fascicle somatotopy is also important in the surgical approach to disorders of peripheral nerves.

“…3 Some sensory fibers to the wrist joint are also carried. The AIN syndrome may follow any injury to the nerve, including penetrating injury or fracture 4 or nerve entrapment due to enlarged bicipital bursae or compression by fibrous bands between the heads of the pronator teres muscle. 5 Many cases resolve spontaneously without a clear underlying cause.…”

This report details previously undescribed sonographic findings in the anterior interosseous nerve syndrome. Loss of muscle bulk, increased reflectivity, reduced perfusion on Doppler sonography, and lack of active contraction of the affected muscles were observed. These findings can aid in the localization of the pathologic process and in the exclusion of tendon rupture. Dynamic observation of muscle function and Doppler changes after exercise can also help identify the muscles involved. Both sonography and MRI may be useful in the evaluation of patients with the anterior interosseous nerve syndrome and other peripheral neuropathies. © 1999 John Wiley & Sons, Inc.

“…Spinner and Schreiber ( 1969) were convinced that the syndrome is due to traction of the interosseous nerve 2-3 cm below the elbow joint where it passes through a connective tissue arch arising from the deep head of the pronator teres (Fig 1).…”

“…The fact that the interosseous nerve has many anatomical variations (Spinner andSchreiber 1969, Gille et al 1978) may also explain why the syndrome is sometimes present with little dislocation of the distal fragment Gille et al ( 1979) also mentioned that besides the long flexors of the thumb and the index finger the pronator quadratus is also affected, a fact which is of minor functional significance.…”
