Abstract
Objective
To compare dual-target injection with standard US-guided subacromial injection in patients with SIS and possible disorders of the biceps long-head tendons.
Design
Double-blind, randomized controlled trial.
Setting
Rehabilitation outpatient clinic.
Participants
Patients with SIS (N=60).
Intervention
(1) US-guided standard subacromial bursa and (2) dual-target (subacromial bursa plus proximal biceps long-head tendon) injection, with 40-mg triamcinolone acetonide administered to patients in each group.
Main Outcome Measures
Clinical assessments were performed at baseline. The outcomes, including results from a self-administered questionnaire, the Shoulder Pain and Disability Index (SPADI), and a self-pain report, the visual analogue scale (VAS) scores for pain at rest, at night, and during overhead activities, were evaluated at baseline and at the first and third months post-intervention.
Results
No significant difference was observed in baseline evaluations between groups (n = 30 in each treatment arm) prior to injections. Both groups exhibited significant SPADI and VAS-score improvements after the first month. The dual-target injection group had less rebounding pain at the 3-month follow-up. The standard injection group had more patients reporting worsening pain within 1 day post-injection.
Conclusion
US-guided dual-target corticosteroid injection showed similar short-term efficacy to standard subacromial injections, but with an extended duration of symptom relief. Therefore, dual-target corticosteroid injections may be useful for shoulder-pain treatment in patients with SIS.
