Summary

Hip fractures are among the most common orthopedic traumas, particularly in elderly patients, and are usually associated with significant pain during positioning for spinal anesthesia. Adequate pain control during positioning can improve patient comfort and facilitate successful administration of anesthesia. The pericapsular nerve group (PENG) block has recently been introduced as a regional anesthesia technique that targets articular branches of the femoral, obturator, and accessory obturator nerves, and has been proposed as a method to reduce pain related to hip fracture positioning.

This study is designed to compare the efficacy of preoperative PENG block versus no block in patients undergoing proximal femoral nailing surgery under spinal anesthesia. The primary objective is to assess its effect on positioning pain using visual analog scale (VAS) scores. Secondary objectives include evaluating its impact on postoperative analgesic consumption, time to first rescue analgesic, and potential side effects.

Conditions

  • Hip Fractures (ICD-10 72.01-72.2)
  • Postoperative Pain Management After Total Hip Arthroplasty
  • Elderly Patients
  • Regional Anesthesia

Interventions

PROCEDURE

Pericapsular nerve group (PENG) block

A single-shot PENG block was administered preoperatively using ultrasound guidance. The block was performed with the patient in the supine position, and 20 mL of local anesthetic (0.25% bupivacaine) was injected between the psoas tendon and the superior pubic ramus to achieve analgesia of the anterior hip capsule.

PROCEDURE

Standard Spinal Anesthesia (Control)

Patients in this arm were managed according to standard care protocols for spinal anesthesia in hip fracture surgery. No preoperative regional block was performed. Pain scores and postoperative tramadol use were measured for comparison with the experimental arm.
