Snapping tendon syndrome: hip tenography with fluoroscopic monitoring.

Abstract

The snapping tendon syndrome may be caused by abnormalities of the fascia lata, gluteus maximus muscle, or less commonly, the iliopsoas tendon. One case is reported in which fluoroscopic monitoring after computed tomography-guided injection of contrast material confirmed the diagnosis of snapping iliopsoas tendon syndrome.

Surgical Correction of the Snapping Iliopsoas Tendon in Adolescents

“…In 1988, Staple et al 13 used tenography to demonstrate snapping of the iliopsoas tendon over the iliopectineal eminence. This technique involves injecting the tendon itself with contrast material and then observing its movement under fluoroscopic examination.…”

Sonographic anatomy and dynamic study of the normal iliopsoas musculotendinous junction

“…The snapping iliopsoas syndrome, defined by the association of a snap in the hip and pain or discomfort, has been a subject of interest in both the surgical and radiological literature [14][15][16][17][18][19]. Some articles have emphasised the role of dynamic US in the evaluation of snapping hips [4,10,[19][20][21].…”

Diagnóstico por imagem nas síndromes do estalido ou do ressalto

“…In the past, iliopsoas tenography and bursography were utilized for allowing a dynamic study and characterization of sudden snapping of the iliopsoas tendon on fluoroscopic images (16) . However, ultrasonography is currently a preferable method for being non-invasive and allowing a dynamic evaluation during maneuvers that trigger the snapping (17) .…”
