Jp. Vaccaro et al., ILIOPSOAS BURSA IMAGING - EFFICACY IN DEPICTING ABNORMAL ILIOPSOAS TENDON MOTION IN PATIENTS WITH INTERNAL SNAPPING HIP SYNDROME, Radiology, 197(3), 1995, pp. 853-856
PURPOSE: To evaluate the efficacy of both iliopsoas bursa imaging and
therapeutic injections for determination of the cause of pain in patie
nts with internal snapping hip syndrome. MATERIALS AND METHODS: Twelve
patients underwent iliopsoas bursa imaging. One patient underwent the
procedure bilaterally and five underwent repeated studies for a total
of 21 studies. Eight patients also received therapeutic injections af
ter bursa imaging. RESULTS: Abnormal motion of the iliopsoas musculote
ndinous unit that occurred synchronously with the snap was revealed in
15 of the 21 studies. Four studies revealed additional information th
at contributed to symptoms. Eight patients received therapeutic inject
ions with relief of symptoms that ranged from 2 weeks to 2 years. CONC
LUSION: Iliopsoas bursa imaging is a simple, rapid, and reproducible m
ethod with which abnormal iliopsoas tendon motion tan be documented in
patients with internal snapping hip syndrome and is also useful for d
iagnosis of other causes of atypical hip pain. Therapeutic injection i
nto the iliopsoas bursa may delay or obviate surgery.
