What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This trial compares two types of nerve blocks—the newer PENG block and the traditional femoral nerve block—given before spinal anesthesia for hip fracture surgery. The goal is to see which one better reduces pain and helps patients sit comfortably for the spinal injection. Adults aged 50 and older with hip fractures are being studied to find the most effective approach.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a nerve block procedure using bupivacaine
What this could lead to
If one nerve block proves better, it could make spinal anesthesia easier and less painful for people with hip fractures.
What could go wrong
This is a small, single-center trial, so results may not apply broadly. Both blocks carry risks like infection or nerve damage.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 50 years or older. * Diagnosis of proximal femoral fracture. * Scheduled to undergo surgical repair under spinal anesthesia. * American Society of Anesthesiologists (ASA) physical status I-III. * Able to provide written informed consent. Exclusion Criteria: * 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. * Pre-existing neurological disease affecting lower extremity function or sensory assessment. * Cognitive impairment preventing reliable study participation or outcome assessment. * Previous lumbar spine surgery. * Polytrauma. * Body mass index (BMI) \<18 kg/m² or \>40 kg/m². * Current anticoagulant therapy that precludes neuraxial anesthesia or peripheral nerve block according to institutional practice.
