PENG versus interscalene nerve block for shoulder arthroscopy and hand movement effects
Is Pericapsular Nerve Group (PENG) Block Superior to Interscalene Nerve Block Regarding Motor Power Affection in Shoulder Scope Surgeries? A Randomised Comparative Study.
This test will see if a PENG nerve block gives adults having shoulder arthroscopy good pain relief while causing less arm weakness than the standard interscalene block.

What this trial studies
Adults scheduled for shoulder arthroscopy will receive either a pericapsular nerve group (PENG) block or a standard interscalene nerve block performed under ultrasound guidance. Motor power of the affected limb will be measured after the block and again after surgery, and postoperative pain scores will be recorded. The trial compares analgesic effectiveness and the degree of motor blockade between the two techniques. Procedures are conducted at Cairo University using standard ultrasound equipment.
Who should consider this trial
Good fit: Adults (ASA physical status 1–2) with BMI under 35 who are scheduled for shoulder arthroscopy expected to last about 90–120 minutes are ideal candidates.
Not a fit: Patients with higher surgical risk (ASA 3–4), allergy to local anesthetics, significant bleeding/clotting issues, recent anticoagulant use, or active local infection at the injection site are unlikely to benefit or may be excluded.
Why it matters
Potential benefit: If successful, patients could get effective postoperative pain relief with less arm weakness, enabling earlier mobilization and potentially easier recovery.
How similar studies have performed: Interscalene block is an established method for shoulder analgesia, while use of the PENG block in shoulder procedures is relatively novel with limited prior evidence.
