Background: With the development of scientific technology, applications of high-resolution ultrasound have rapidly developed in biomedical fields. High-resolution sonography clearly depicts peripheral nerve size spaces occupying lesions and anatomic variants along the entire length of the normative nerve Aim; Assessment of efficacy of ultrasound in evaluation of degree of traumatic nerve injury methods This prospective study was carried out during the period from June 2019 to April 2020 and included a hundred participants. All patients were referred to the radiology department of Benha university from the emergency department and outpatient clinic of surgery department of Benha university hospital. Results: diagnosis and characterization of turmeric peripheral nerve injury using ultrasound Conclusion; US can be used to facilitate the preoperative diagnosis and planning of the optimal treatment strategy as it can permit tracing the injured nerve at the lesion site and the neuroma's extension. Finally, US has high accuracy for detection, diagnosis, assessment and treatment planning of traumatic peripheral nerve lesions.
