“…Likewise, scleroderma is highly unlikely because only one side is affected, there is no Raynaud’s phenomenon, and there are no nail fold vascular changes. FIS must be distinguished from other conditions, including de Quervain’s tenosynovitis [ 24 ], superficial sensory radial nerve neuropathy due to nerve damage or external pressure (Wartenberg syndrome) [ 25 , 26 , 27 ], osteoarthritis of the first carpometacarpal joint, and intersection syndrome at the wrist [ 3 , 13 , 14 , 25 , 27 , 28 , 29 ]. Table 2 summarizes the overlapping features and differences between these conditions.…”

“…The literature on FIS in rheumatology and related journals is surprisingly meager. Suffice it to say that the authors reviewed thirty-two rheumatology journals listed in PubMed, finding only two Letters to the Editor [ 14 , 15 ]. In addition, among the twenty-seven physical medicine and rehabilitation journals, only four reports were found: one case report [ 9 ] and three case series [ 7 , 11 , 16 ].…”

Background: Forearm intersection syndrome causes pain, swelling, and a rub at the dorsal distal forearm where the first extensor compartment muscles intersect with the second compartment tendons. Although primary care settings tend to treat mild cases, high-performance athletes may suffer from severe symptoms that require surgery. This proof-of-concept study aims to help detect the anatomical substrate of forearm intersection syndrome using palpation and ultrasonography when available. Methods: Five individuals were studied using independent palpation and ultrasonography to identify the first dorsal compartment muscles and the second dorsal compartment tendons. The distances between the dorsal (Lister’s) tubercle of the radius and the ulnar and radial edges of the first dorsal compartment muscles were measured to determine the location and extent of the muscle–tendon intersection. The palpatory and ultrasonographic measurements were compared using descriptive statistics and the paired t-test. Results: The mean distances from the dorsal tubercle of the radius to the ulnar and radial borders of the first dorsal compartment muscles were 4.0 cm (SE 0.42) and 7.7 cm (SE 0.56), respectively, based on palpation. By ultrasonography, the corresponding distances were 3.5 cm (SD 1.05, SE 0.47) and 7.0 cm (SD 1.41, SE 0.63). Both methods showed a similar overlap length. However, ultrasonography revealed a shorter distance between the dorsal tubercle of the radius and the ulnar border of the first compartment than palpation (p = 0.0249). Conclusions: Our findings indicate that a basic knowledge of anatomy should help health professionals diagnose forearm intersection syndrome through palpation and, if available, ultrasonography.

“…Intersection syndromes elsewhere in the body have been reported, most notably where the 1st dorsal extensor compartment crosses over the 2nd in the forearm. 1,2 Diagnosis can be confirmed through MRI or ultrasound. Ultrasound findings in intersection syndromes include anechoic fluid with loss of the hyperechoic plane separating the tendons and possible increased power Doppler signal.…”

“…Theoretically, an intersection syndrome can develop at any point where two tendons cross and have no tendon sheath or paratenon separating them, as this predisposes them to increased friction forces and inflammation in the setting of overuse. Intersection syndromes elsewhere in the body have been reported, most notably where the 1st dorsal extensor compartment crosses over the 2nd in the forearm 1,2 . Diagnosis can be confirmed through MRI or ultrasound.…”
