Overview
This study investigates how well ultrasound imaging can identify damage to the radial nerve in patients with a broken upper arm bone (humeral shaft fracture). Some of these patients also have weakness or paralysis in their hand and wrist due to injury to the radial nerve. The study compares patients with and without radial nerve problems to see if early ultrasound scans can accurately detect nerve damage before surgery.
All patients will receive standard care, including surgery to fix the fracture. Those with nerve problems will also have the nerve explored during surgery. The results of the ultrasound will be compared to what is found during the operation. Patients will be followed closely over 12 months to monitor nerve recovery, healing of the bone, and any complications.
The goal is to improve the early diagnosis and management of nerve injuries in arm fractures, using a safe, non-invasive ultrasound scan that could help guide treatment decisions.

- Admitted and followed according to the local clinical protocol with a confirmed diagnosis.
- Underwent required investigations, including high-resolution ultrasonography and/or electromyography (EMG).
- Provided written informed consent to participate in the study.
Exclusion Criteria:
- Pathological fractures due to malignancy or metabolic disorder.
- History of previous humeral fracture or pre-traumatic radial nerve deficit.
- Clinically detected vascular injury or major soft tissue loss accompanying the fracture.
