Interscalene brachial plexus block is the gold standard for perioperative pain management in shoulder surgery. However, this technique would have side effects and potential serious complications. The aim of this study is to compare between the combination of ultrasound guided suprascapular and supraclavicular nerve blocks versus ultrasound guided interscalene brachial plexus block for post operative analgesia after shoulder instability surgery with latarjet procedure.

Inclusion Criteria:

• ASA physical status I-III
• 18-75 years of age, inclusive
• shoulder surgery (LATARJET technique)

Exclusion Criteria:

• contraindications to brachial plexus block (e.g., allergy to local anesthetics, coagulopathy, malignancy or infection in the area)
• existing neurological deficit
• pregnancy
• history of neck surgery or radiotherapy
• severe respiratory disease
• inability to understand the informed consent and demands of the study
