The aim of this study was to compare the efficacy and the safety of
ultrasound (US)-guided vs. blind steroid injections in patients with carpal
tunnel syndrome (CTS). DESIGN: This prospective randomized single-blind clinical
trial included 46 patients with CTS (46 affected median nerves). The subjects
were randomized-to either the US-guided or the blind injection group-before they
received 40 mg of methylprednisolone. They were evaluated using the Boston Carpal
Tunnel Questionnaire symptom/function at baseline and at 6 wks and 12 wks after
injection, and the side effects were noted. RESULTS: The symptom severity and
functional status scores improved significantly in both groups at 6 wks after
treatment, and these improvements persisted at 12 wks after treatment (all P <
0.05). The improvement in symptom severity scores in the US-guided group at 12
wks was higher than in the palpation-guided group (P < 0.05). Average time to
symptom relief was shorter in the US-guided group (P < 0.05). There was no
significant difference between the two groups in terms of side effects (P >
0.05). CONCLUSIONS: Although both US-guided and blind steroid injections were
effective in reducing the symptoms of CTS and improving the function, an earlier
onset/better improvement of symptom relief suggests that US-guided steroid
injection may be more effective than are blind injections in CTS.
