Abstract

BackgroundPrevious work has shown an association between restricted wrist range of motion ROM and upper extremity musculoskeletal disorders in computer users. We compared the prevalence of MRI-identified wrist abnormalities and wrist ROM between asymptomatic and symptomatic computer users.

MethodsMR images at 1.5 T of both wrists were obtained from 10 asymptomatic controls 8 F, 2 M and 14 computer users 10 F, 4 M with chronic wrist pain 10 bilateral; 4 right-side. Maximum wrist range of motion in flexion and radioulnar deviation was measured with an electrogoniometer.

ResultsExtraosseous ganglia were identified in 66.6% of asymptomatic wrists and in 75% of symptomatic wrists. Intraosseous ganglia were identified in 45.8% of asymptomatic wrists and in 75% of symptomatic wrists, and were significantly p < .05 larger in the symptomatic wrists. Distal ECU tendon instability was identified in 58.4% of both asymptomatic and symptomatic wrists. Dominant wrist flexion was significantly greater in the asymptomatic group 68.8 ± 6.7 deg. compared to the symptomatic group 60.7 ± 7.3 deg., p < .01. There was no significant correlation between wrist flexion and intraosseous ganglion burden p = .09

ConclusionsThis appears to be the first MRI study of wrist abnormalities in computer users.

This study demonstrates that a variety of wrist abnormalities are common in computer users and that only intraosseous ganglia prevalence and size differed between asymptomatic and symptomatic wrists. Flexion was restricted in the dominant wrist of the symptomatic group, but the correlation between wrist flexion and intraosseous ganglion burden did not reach significance. Flexion restriction may be an indicator of increased joint loading, and identifying the cause may help to guide preventive and therapeutic interventions.
