Abstract:
Introduction: Current literature reports varied significance
of ulnar styloid fractures (USF) associated with distal radius
fractures. Our study assesses the role of ulnar styloid
fractures and fragment size in surgically managed distal
radius fractures.
Materials and methods: We reviewed patients who
underwent surgical fixation of distal radius fractures between
January 2004 to June 2006. Patients were divided into those
with (Group 1) and without (Group 0) USFs. Post-operative
radiographic parameters, clinical outcomes and overall wrist
function were analysed. Outcomes included ulnar-sided
wrist pain, extensor carpi ulnaris (ECU) tendinitis, triangular
fibrocartilage complex (TFCC) grind test, distal radioulnar
joint (DRUJ) instability and pain. Overall wrist function was
assessed with range of motion and Disabilities of the Arm,
Shoulder and Hand (DASH) score.
Results: Our study cohort included 31 males and 23 females,
and 38.9% of these patients had concomitant USFs. There
was no difference in terms of demographic data and fracture
configuration between groups. Radiographic parameters
were similar, except for palmar tilt, which was significantly
higher in Group 1 (4.6º vs 9.4º, p=0.047). At 24 months,
there were no differences in clinical outcomes and overall
wrist function. A sub-group analysis showed that mean USF
fragment size was larger in patients with a positive TFCC
grind test (3.9mm vs 7.3mm, p=0.033).
Conclusion: The presence of USFs in surgically managed
distal radius fractures does not compromise clinical and
functional outcome. Similarly, the size of USFs does not
impact clinical and functional outcome but is associated with
the presence of a positive TFCC grind test.
