About this trial
Hip fractures are common in older adults and are often associated with severe pain, making it difficult for patients to sit for spinal anesthesia before surgery. Peripheral nerve blocks may improve pain control and facilitate patient positioning, but it remains uncertain whether the Pericapsular Nerve Group (PENG) block provides advantages over the traditional femoral nerve block during the spinal anesthesia procedure.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adults aged 50 years or older.
Diagnosis of proximal femoral fracture.

Disqualifiers
Refusal to participate or inability to provide informed consent.
Coagulopathy or contraindication to spinal anesthesia or peripheral nerve block.
Local infection at the planned injection site.
Known allergy or hypersensitivity to local anesthetics.

Treatments tested in this trial
Ultrasound-Guided Pericapsular Nerve Group (PENG) Block
Procedure/SurgeryUltrasound-guided PENG block performed before spinal anesthesia using 20 mL of 0.25% bupivacaine to provide analgesia for patients undergoing surgery for proximal femur fracture.
Ultrasound-Guided Femoral Nerve Block
Procedure/SurgeryUltrasound-guided femoral nerve block performed before spinal anesthesia using 20 mL of 0.25% bupivacaine to provide analgesia for patients undergoing surgery for proximal femur fracture.
Spinal Anesthesia (bupivacaine)
Procedure/SurgeryStandard spinal anesthesia performed after the assigned peripheral nerve block using intrathecal hyperbaric bupivacaine according to the study protocol.

Trial outcomes
Primary outcomes
1
Spinal Anesthesia Convenience Score (SACS)
Spinal anesthesia convenience will be assessed using the Spinal Anesthesia Convenience Score (SACS), a composite clinical score evaluating the ease of spinal anesthesia based on anatomical landmark palpation, patient cooperation, sitting position quality, pain during passive hip flexion, and pain while maintaining the sitting position. Total scores range from 0 to 11, with higher scores indicating easier spinal anesthesia conditions.
Time frame
During spinal anesthesia procedure (immediately after patient positioning and before initiation of surgery)Secondary outcomes
1
First-Attempt Success of Spinal Anesthesia
The proportion of participants in whom successful intrathecal access is achieved on the first needle insertion attempt.
Time frame
During the spinal anesthesia procedure.2
Number of Spinal Needle Insertion Attempts
The total number of spinal needle insertion attempts required to achieve successful spinal anesthesia.
Time frame
During the spinal anesthesia procedure.3
Duration of Spinal Anesthesia Procedure
Time from the beginning of patient positioning until completion of spinal anesthesia and return to the supine position, measured in minutes.
Time frame
During the spinal anesthesia procedure.4
Anxiety Score
Patient anxiety will be assessed using an 11-point Numeric Rating Scale (NRS) ranging from 0 (no anxiety) to 10 (maximum anxiety). Lower scores indicate less anxiety.
Time frame
Before peripheral nerve block, 30 minutes after block placement, and immediately before surgical incision (after spinal anesthesia).Sponsors and contacts
