Abstract
Background: Peripheral nerve disorders happen when one or more peripheral nerves are damaged. Damaged nerves may not carry messages correctly, or they may not work at all. As a result, you may have pain, trouble walking, or a variety of other problems, depending on which nerves are involved. Peripheral nerve disorders are very common. There are more than 100 different types. Aim: To detect the value of high resolution ultrasound in assessment and characterization of some median and ulnar nerve lesions, Including, mainly, compressive, traumatic and inflammatory nerve injuries. Patients and Methods: 26 participants were included in our study either from outpatient clinics (neurology, rheumatology and diabetic clinics) or inpatient wards (vascular surgery department). The study was designed as a case series study; we studied 26 cases with diabetic peripheral neuropathy, carpal tunnel syndrome and traumatic/neoplastic nerve lesions. All selected cases were subjected to proper history taking and ultrasound detection of cross-sectional area (CSA) measurements of median/ulnar nerves in cases of diabetic peripheral neuropathy/carpal tunnel syndrome, compression/flattening of median nerve in cases of carpal tunnel syndrome, loss of integrity in traumatic nerve lesions and neuroma incontinuty in traumatic/neoplastic nerve lesions. Results: Regarding the ultrasound findings of the peripheral nerves (median/ulnar nerves), there were 38.5% cases were carpal tunnel syndrome, 23.1% were ulnar nerve diabetic neuropathy and 3.8% were complete tear of digital branch of median N, median N complete transection with neuroma, median N entrapment by scar tissue, median N injury neuroma old crush injury, median N injury with neuroma in continuity, median N injury with small hematoma& bifid median N, median ulnar nerve traumatic injury, ulnar nerve crush injury neuroma, ulnar nerve penetrating wound neuroma and ulnar nerve shwanoma. We found that there are significant increase in ulnar/median nerves CSA among diabetic patients with diabetic peripheral neuropathy (DPN)/patients with carpal tunnel syndrome (CTS), compression/flattening of median nerve in patient with CTS, loss of integrity in cases of traumatic nerve lesions and neuroma incontinuty of traumatic/neoplastic nerve lesions. Conclusion: High resolution ultrasound of median and ulnar nerves proved very helpful in the early diagnosis and distinction of various median and ulnar nerves lesions seen in patients with carpal tunnel syndrome, ulnar nerve diabetic neuropathy clinically suspected, patients with median/ulnar nerves traumatic lesions and patients with ulnar nerve neoplastic nerve lesions. Upper limb peripheral nerve ultrasonography can serve as a useful diagnostic tool in the diagnosis of peripheral nerve lesions
