Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants will be randomised into two groups. Patients assigned to the PENG group will receive spinal anaesthesia with local anaesthetic (isobaric bupivacaine) alone and a PENG block. Patients assigned to the intrathecal morphine (ITM) group will receive spinal anaesthesia with a mixture of local anaesthetic (isobaric bupivacaine) and morphine (100 mcg) and a sham PENG block to ensure patient blinding.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators believe that PENG block provides postoperative analgesia equivalent to intrathecal morphine. The research team plans to enrol 80 patients and randomise them to two groups - pericapsular nerve block (PENG) or intrathecal morphine (ITM). After written informed consent, patients will be allocated to one of the two groups according to a computer-generated randomisation list. The PENG group will receive central spinal anaesthesia with 12.5 mg isobaric bupivacaine followed by a PENG block with 20 cc of 0.75% ropivacaine. ITM groups will receive central spinal anaesthesia with 12.5 mg isobaric bupivacaine and 100 mcg morphine followed by a sham PENG block.
During the surgery, 0.15 mg/kg of dexamethasone iv, 1g acetaminophen iv, 30mg ketorolac iv and 40mg/kg magnesium iv will be administered for post operative analgesia.
In the post-operative care unit, pain management will be provided with as needed with 2mg of IV morphine at ten minute intervals for pain scores \>3. Once spinal motor block has ceded, the patients will be transferred to the surgical ward with a morphine patient controlled analgesia (PCA) pump. The pump parameters will allow 2 mg boluses of morphine with a 10-minute lockout and a maximum dose of 40 mg in 4 hours. Basal analgesia will be provided with paracetamol (1g/6h) and ibuprofen (400mg/8h). Ondansetron (4mg IV) will be provided in case of nausea or vomiting. A research assistant will conduct post operative visits at 2h, 1 day and 2 days post-operatively to record research data. Functional testing will be performed at day 1 and 2 by physiotherapy personnel.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
PENG group
Pericapsular nerve group block
Pericapsular nerve group block (PENG)
Spinal anesthesia with intrathecal injection of 12.5 mg of isobaric bupivacaine will be performed, followed by a PENG block.
After skin disinfection, a low frequency curvilinear ultrasound probe (2-5 MHz 8870, BK ultrasound, Peabody Massachussets, US) with a sterile covering will be used to identify the anterior inferior iliac spine, the pubic eminence and the psoas tendon with its fascial plane. A 22 gauge 10cm block needle (Sonoplex® Pajunk, Geisingen, DE), will be used to enter the fascial plane and 20ml of 0.75% Ropivacain (Fresenius Kabi, Krienz CH) will be injected.
ITM group
intrathecal morphine injection
Intrathecal morphine
Spinal anesthesia will be performed as follows: patient will be placed in the lateral decubitus position on the non-operative side. Using sterile gloves red chlorhexidine 2% alcohol solution will be used for skin disinfection. The site will be secured with a sterile drape, and the L4-L5 lumbar space identified. After subcutaneous local infiltration with 1% lidocaine, a 25G Whitacre pencil point spinal needle will be used to access the intrathecal space with free flow of cerebrospinal fluid as confirmation. A mixture of 12.5 mg of isobaric bupivacaine and 100 mcg of morphine will be administered intrathecally.
After the spinal anesthesia, the intrathecal morphine (ITM) group will receive a sham PENG block with the block needle inserted subcutaneously, the anesthesiologist using the same verbal block confirmation commands "aspirate, inject" but the needle withdrawn without injection. This will create the appearance of an identical cutaneous injection site to ensure patient blinding.
