Comparison of the Effectiveness of the Ultrasound- Guided Subacromial, Acromioclavicular with Subacromial Injection and Suprascapular Nerve Block in Patients with Shoulder Subacromial Impingement Syndrome: A Randomized Controlled, Single Blind, Clinical T

Q: What is the clinical evidence from this study?

Study design: RCT. Population: Shoulder subacromial impingement syndrome (SIS) (n=90). Intervention: Ultrasound-guided subacromial plus acromioclavicular joint injection or suprascapular nerve block vs. Ultrasound-guided subacromial injection alone. Primary outcome: Visual analogue scale (VAS) score at 24 weeks (p=<0.001).

Key result

Ultrasound-guided subacromial plus acromioclavicular joint injection and suprascapular nerve block maintained significant pain reduction at 24 weeks compared to subacromial injection alone (p<0.001).

Why the study?

Acromioclavicular joint pathologies may be a common etiological factor with subacromial impingement syndrome and should be considered in treatment alongside standard subacromial injection or suprascapular nerve block.

Does combined subacromial and acromioclavicular joint injection or suprascapular nerve block improve pain and function compared to subacromial injection alone in patients with shoulder subacromial impingement syndrome?

Population

90 patients with chronic shoulder pain associated with SIS

Comparison

US-guided SA injection vs US-guided SA+ACJ injection vs US-guided SSNB

Design

Prospective, randomized, single-blind controlled trial

Follow-up

24th week

Overview

May support combined injections for sustained shoulder pain relief; hypothesis-generating pending randomized confirmation.

Randomization

Multicenter

Structured PICO

Population

90 adults aged 18-65 years with chronic shoulder pain due to subacromial impingement syndrome, followed for 24 weeks.

Intervention

Ultrasound-guided subacromial (SA) injection + acromioclavicular joint (ACJ) injection (5 mL 0.25% bupivacaine + 20 mg methylprednisolone in SA, 2 mL 0.25% bupivacaine + 20 mg methylprednisolone in ACJ) OR ultrasound-guided suprascapular nerve block (SSNB) (10 mL 0.25% bupivacaine + 40 mg methylprednisolone).

Comparator

Ultrasound-guided subacromial (SA) injection alone (5 mL 0.25% bupivacaine + 40 mg methylprednisolone).

Outcome

Visual analogue scale (VAS) scores measured before treatment and at the 2nd week, 4th, 12th and 24th week after treatment.patient reported

Main Result

Absolute Event Rate: 22% vs 30%

p-value: p=<0.001

In patients with subacromial impingement syndrome, suprascapular nerve block and combined subacromial/acromioclavicular joint injections provide better long-term pain and functional improvement at 24 weeks compared to subacromial injection alone.

Limitations

Absence of a true placebo control group
Could not be done double-blindly due to the different injection sites and techniques
Absence of a control group
Could not be done double-blindly due to the fact that SA+ACJ injection was applied from 2 sites in the group

Ökmen et al. (2024) conducted an RCT in Shoulder subacromial impingement syndrome (SIS) (n=90). Ultrasound-guided subacromial plus acromioclavicular joint injection or suprascapular nerve block vs. Ultrasound-guided subacromial injection alone was evaluated on Visual analogue scale (VAS) score at 24 weeks (p=<0.001). Ultrasound-guided subacromial plus acromioclavicular joint injection and suprascapular nerve block maintained significant pain reduction at 24 weeks compared to subacromial injection alone (p<0.001).
