Abstract
Purpose: To report the magnetic resonance imaging (MRI) findings in athletic
injuries of the extensor carpi ulnaris (ECU) subsheath, assessing the utility of
gadolinium-enhanced (Gd) fat-saturated (FS) T1-weighted sequences with wrist
pronation and supination.
Methods and Materials: Sixteen patients (13 males, 3 females; mean age 30.3
years) with athletic injuries of the ECU subsheath sustained between January 2003
and June 2009 were included in this retrospective study. Initial and follow‑up 1.5-T
wrist MRIs were performed with transverse T1-weighted and STIR sequences in
pronation, and Gd FS T1-weighted sequences with wrist pronation and supination.
Two radiologists assessed the type of injury (A to C), ECU tendon stability,
associated lesions and rated pulse sequences using a three-point scale: 1 = poor,
2 = good and 3 = excellent.
Results: Gd-enhanced FS T1-weighted transverse sequences in supination (2.63)
and pronation (2.56) were most valuable, compared with STIR (2.19) and T1
weighted (1.94). Nine type A, one type B and six type C injuries were found. There
were trends towards diminution in size, signal intensity and enhancement of associated
pouches on follow‑up MRI and tendon stabilisation within the ulnar groove.
Conclusion: Gd-enhanced FS T1-weighted sequences with wrist pronation and
supination are most valuable in assessing and follow‑up athletic injuries of the
ECU subsheath on 1.5-T MRI.
