Summary

A Comparative study Between Ultrasound guided Interscalene Block and Combined Ultrasound guided suprascapular and axillary nerve blocks for proximal humerus fracture Surgeries. The aim of this study is to investigate whether (Suprascapular nerve block) and (Axillary nerve block) are effective in providing analgesia for shoulder surgery as an (Interscalene block), while minimizing the occurrence of hemi-diaphragmatic paralysis. We hypothesized that analgesia with a (Suprascapular nerve block and Axillary nerve block) would be noninferior compared with patients receiving an interscalene block and the incidence of hemi-diaphragmatic paralysis would be significantly lower with (Suprascapular nerve block and Axillary nerve block) in proximal humerus fracture surgeries.

• Proximal Humerus Fractures

Interventions

Type	Name	Description
PROCEDURE	Patients will receive Supra scapular nerve block and Axillary nerve block.	Suprascapular nerve block will be done by posterior approach with the patient sitting up and leaning forward. The linear ultrasound probe will identify the suprascapular nerve, after that we will inject aliquots of Sunnypivacaine 0.5% 15 ml after negative aspiration of blood. For the axillary nerve block, the ultrasound transducer will be placed in a sagittal plane over the humeral head on the posterior aspect of the arm to identify the deltoid muscle, neck of the humerus, the teres minor muscle, the circumflex humeral artery, and the triceps muscle. After the neurovascular quadrangular space identification and observing the deltoid muscle response to stimulation, a local anesthetic (10 ml 0.25% Sunnypivacaine) will be injected with the in-plain technique.
PROCEDURE	Patients will receive Interscalene block.	Interscalene nerve block will be done ultrasound-guided using a linear array ultrasound transducer. While the patient is in the supine position, the head will be rotated to the contralateral side of the block. Ultrasound scanning will be performed in the transverse plane with long axis of the probe parallel to clavicle to visualize the brachial plexus between the anterior and middle scalene muscles. A 5-cm 22-gauge insulated needle will then be inserted in line with the probe in a lateral-to-medial needle orientation. Local anesthetic solution will then be injected in 15-ml aliquots Sunnypivacaine 0.5% after negative aspiration for blood to achieve spread posterior to or between the C5 and C6 nerve roots.
