Suprascapular Nerve Block With Oral Gabapentin For Pain Management In Frozen Shoulder

Study Overview
=================
Brief Summary
-----------------
The patients will be randomly allocated into two equal groups (each 20 patients) using sealed opaque numbered envelopes: Control Group (C Group) : Patients receive continuous US suprascapular nerve block only. Gabapentin Group (G Group) : Patients receive continuous US suprascapular nerve block with oral gabapentin 300 mg once daily at bed time. Both groups compared as regard: Visual Analogue Scale Range of passive and active movements Patients satisfaction complication related to block The total dose of diclofenac sodium

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: Control Group (C Group)<br>Patients will receive continuous US suprascapular nerve block only. | Procedure: Ultrasound Guided Continuous Suprascapular Nerve Block With methyl prednisolone and marcaine<br>* The high frequency linear ultrasound transducer (Sonosite 6-13 MHz) in a transverse orientation will be placed over the scapular Spine. Moving the transducer cephalad the suprascapular fossa will be identified. 18 gauge touhy needle will be inserted in plane after subcutaneous local anesthesia infiltration with 1 ml lidocaine 2% Real-time imaging will be used to direct injection of 2 ml lidocaine 2% to test perineural spread of injectate after confirmation of the position of tip of needle injection of 40mg methyl prednisolone diluted in 5 ml bupivacaine 0.5% will be done through the needle to anesthetize the nerve and create space for catheter insertion. After catheter insertion another 2 ml lidocaine 2% will be injected through the catheter to confirm position perineural in the scapular notch. Lastly Catheter will be fixed via skin tunnel and secured with skin sutures and adhesive tap.<br>* Other names: Oral gabapentin 300 mg at bed time in GG;|
