“…We have noted that the supinator muscle is relaxed in passive supination, but we do not know if active contraction of this muscle can compress the nerve. Some instances of passive rupture of the nerve by stretching during sporting activities have been reported [7], and compression at several levels, notably during rotation [4], seems to confirm our observations.…”

“…Others consider that the syndrome results from intermittent and dynamic compression of the nerve in the proximal part of the forearm associated with repeated pronation and supination [1,4,9,14,15]. This may explain the very slow development of symptoms, and macroscopic compression of the nerve in 46 to 88% of cases.…”

“…2e5 Kotani et al reported PIN paralysis after arm squat exercise and needlework. 2 The nerve constrictions of the PIN were observed between the arcade of the Frohse and a point of bifurcation of the supinator motor branch and external neurolysis with epineurotomy was performed. It was suggested that the constrictions and the adhesions of the nerve were caused by twisting of the nerve in pronation and supination of the forearm.…”

a b s t r a c tWe report a rare case of posterior interosseous nerve (PIN) paralysis in a tennis player. The PIN, a 2 cm section from a bifurcation point of the radial nerve, presented increased stiffness in the surgical findings and treated with free sural nerve grafting after excision of the degenerative portion of the PIN. We speculate that PIN paralysis associated with hourglass-like constriction can be caused and exacerbated by repetitive forearm pronation and supination in playing tennis.

“…Whatever the trigger mechanism, it was presumed that a local inflammation around the nerve might result in local edema and irritation and stiffness of nerve fascicles, making them less adaptable to bending forces. 15,20,21 This was thought to lead to subsequent adhesion to adjacent structures, as happens during elbow flexion/extension, repetitive forearm rotation, repetitive movements of abduction, and/or internal rotation of the shoulder. 3-5,10,12 Moreover, transversely running vascular structures, as well as the muscles under which the nerves glide, creating friction or adhesions, may constitute mechanical obstacles that function as constriction bands or points of fixation, predisposing the patient to nerve torsions and constrictions.…”
