Background And Objectives: The unifying articular theory suggests that intraneural ganglion cysts in the cubital tunnel arise from the elbow joint and are connected to the ulnar nerve through an articular branch. This study aimed to report our clinical experience with these cysts and our surgical findings and outcomes.

Methods: We retrospectively analyzed 13 patients who underwent surgery for cubital tunnel syndrome caused by an intraneural ganglion cyst of the ulnar nerve.

Patients with end-stage kidney disease may require creation of an arteriovenous fistula in order to receive hemodialysis treatment. The creation may result in several complications, including carpal tunnel syndrome. Early diagnosis and treatment are essential to relieve symptoms, prevent permanent nerve damage, and improve quality of life.

Objective: To evaluate the stiffness of the sciatic nerve by shear wave elastography (SWE) and to determine whether SWE can be used to predict diabetic foot ulcer (DFU) in a patient with diabetic peripheral neuropathy (DPN).

Methods: Sixteen patients (thirty-two lower limbs) with unilateral DFU were studied retrospectively. The ultrasonographic parameters including cross-sectional area (CSA) of sciatic nerve, intraneural blood flow, peak systolic velocity (Vmax) and resistive index (RI) in the intraneural artery of the sciatic nerve, and the SWE stiffness value of the sciatic nerve were measured.

Introduction: Ulnar mononeuropathy at the elbow is the second most frequent neuropathy in humans. Diagnosis is based on clinical and electrophysiological criteria and, more recently, also on ultrasound. Cross-sectional ultrasound is currently the most valued, although longitudinal ultrasound allows assessment of the entire affected trajectory of the nerve in a single view, but always in a straight line with no changes in direction, as in the extended elbow.

Article Synopsis
  • The study investigates the effectiveness of ultrasound as a diagnostic tool for cubital tunnel syndrome (CuTS) compared to traditional electrodiagnostic studies, focusing on ulnar nerve cross-sectional area (CSA) and intraneural vascularity as indicators of disease extent.
  • Results show a strong correlation between increased CSA and decreased motor nerve conduction velocity (MNCV), but CSA alone does not effectively measure the severity of the condition; however, power Doppler ultrasound proves to be highly predictive for severe CuTS cases.
  • The combination of measuring nerve CSA, using the Boston Carpal Tunnel Questionnaire for symptom evaluation, and power Doppler ultrasound offers a promising approach for assessing CuTS, potentially improving diagnosis and treatment planning.
