“…In each of our 13 patients, HRUS allowed clear visualization of edema in the affected PIN with the typical impairment of tubular nerve structure. According to the literature, this loss of fascicular structure and increased hypoechogenicity are due to edema and vasocongestion . In addition, an obvious caliber change immediately proximal to the entrance into the supinator muscle at arcade of Frohse was seen.…”

“…The arcade of Fröhse can be classified as tendinous, musculotendinous, muscular, or membranous. The tendinous type is considered a significant risk factor for PIN syndrome, with the incidence ranging from 64% to 87% in different studies [ 10 ]. In this study, of the six patients without masses (a ganglion cyst or a neurogenic tumor), four patients showed swelling immediately proximal to the level of the arcade of Fröhse.…”

“…In supination, the PIN moves laterally, lengthens, and rotates in the anticlockwise direction as the superficial layer of the supinator muscle is relaxed. In pronation, the opposite situation occurs, in which the superficial layer of the supinator muscle is tightened and compresses the PIN passively [ 10 ].…”

“…Other structures, including the borders of adjacent muscles and vessels, can also compress the PIN [ 1 ]. Ganglion cysts, lipoma, or synovial pathologies, as well as radial head fracture and Monteggia fracture-dislocation, may also cause compression of the PIN [ 9 , 10 ]. The clinical findings of PIN syndrome include weakness in the extension of the fingers, atrophy of the forearm muscles, and localized pain in the lateral aspect of the elbow and proximal forearm [ 1 ].…”

PurposeThe purpose of this study was to evaluate the ultrasonographic findings associated with posterior interosseous nerve (PIN) syndrome.MethodsApproval from the Institutional Review Board was obtained. A retrospective review of 908 patients' sonographic images of the upper extremity from January 2001 to October 2010 revealed 10 patients suspicious for a PIN abnormality (7 male and 3 female patients; mean age of 51.8±13.1 years; age range, 32 to 79 years). The ultrasonographic findings of PIN syndrome, including changes in the PIN and adjacent secondary changes, were evaluated. The anteroposterior diameter of the pathologic PIN was measured in eight patients and the anteroposterior diameter of the contralateral asymptomatic PIN was measured in six patients, all at the level immediately proximal to the proximal supinator border. The size of the pathologic nerves and contralateral asymptomatic nerves was compared using the Mann-Whitney U test.ResultsSwelling of the PIN proximal to the supinator canal by compression at the arcade of Fröhse was observed in four cases. Swelling of the PIN distal to the supinator canal was observed in one case. Loss of the perineural fat plane in the supinator canal was observed in one case. Four soft tissue masses were noted. Secondary denervation atrophy of the supinator and extensor muscles was observed in two cases. The mean anteroposterior diameter of the pathologic nerves (n=8, 1.79±0.43 mm) was significantly larger than that of the contralateral asymptomatic nerves (n=6, 1.02±0.22 mm) (P=0.003).ConclusionUltrasonography provides high-resolution images of the PIN and helps to diagnose PIN syndrome through visualization of its various causes and adjacent secondary changes.

“…4). 12,90,143 These are rare but include adhesions between the brachialis and brachioradialis muscles, the edge of the extensor carpi radialis brevis (disputed by Werner 178 ), fibrous bands associated with the supinator muscle, and a set of vascular branches The nerve has spontaneously subluxed out of the ulnar groove, which is marked by the forceps tips. Note the expansion of the nerve at the site of subluxation over the medial humeral epicondyle.…”
