This clinical trial is focused on patients who have a proximal femur fracture, which is a type of hip fracture. The study is investigating the use of morphine, a medication commonly used to relieve pain. In this trial, morphine will be administered intrathecally, meaning it is injected into the space around the spinal cord, to see if it provides better pain relief compared to other methods of giving pain medication.

The purpose of the study is to determine if this method of administering morphine results in better pain management for patients undergoing surgery for a proximal femur fracture. Participants will be randomly assigned to receive either the intrathecal morphine or the standard pain treatment. The study will monitor various aspects of pain relief, such as how much pain the patients feel at rest and during movement, and how long it takes before they need additional pain medication.

Throughout the study, researchers will also keep track of any side effects, such as breathing difficulties, low blood pressure, slow heart rate, nausea, vomiting, and itching. The effectiveness of treatments for these side effects will also be evaluated. The study aims to provide valuable information on whether intrathecal morphine is a more effective pain management option for patients with hip fractures undergoing surgery.
