Intraoperative Measurement of Pressure Adjacent to the Ulnar Nerve in Patients With Cubital Tunnel Syndrome

摘要: Purpose Little is known about whether the pressure adjacent to ulnar nerve actually increased in patients with cubital tunnel syndrome or if it a causative factor. We measured during surgery and verified not there was an association patient age, duration of disease, motor conduction velocity, severity neuropathy. Methods Eight elbows 8 average age 62 years were treated surgically extraneural pressures within by using fiberoptic microtransducer. Pressure 3 times elbow fully extended then flexed 130°. The transducers placed at 1, 2, cm distal proximal edge Osborne ligament. neuropathy evaluated according Akahori's classification. palsy graded as stage III 5 IV patients. Results retinaculum 105, 29, 18 mm Hg, respectively. 1 2 significantly higher flexion than extension. There also positive correlation between but this significant correlated neuropathy, disease Conclusions compression might be factor syndrome.
