Filter by:This study aims to assess the role of US and SWE in diagnosis of CuTS and localization of its underlying etiology and verifying whether it can be diagnosed and graded based on US findings, especially quantitaive ulnar nerve stiffness data obtained using SWE, compared to ENMG and intraoperative findings (as gold standard)
Carpal tunnel syndrome and compression of the ulnar nerve at the elbow are common pathologies, which are treated surgically. Diagnosis is usually based on an electromyogram (EMG), as well as symptomatology, etiology of typical symptoms and an evocative clinical examination. Provocative tests performed in consultation include the Tinel and Phalen sign for the carpal tunnel, and the Tinel and prolonged flexion sign for the ulnar nerve at the elbow. The Scratch Collapse Test (SCT) has recently emerged as a new provocation test to help diagnose nerve compression in the upper limb. This non-invasive, pain-free test looks for a reduction in the force of external rotation of the shoulder by applying resistance (the doctor's arm), before and then after a sensory stimulus by "scratching" the area of compression. Nevertheless, this test remains controversial and not based on objective measurements. Our aim is therefore to assess shoulder external rotation force, and thus TBS, objectively with a dynamometer, before and after stimulation in cases of median nerve compression syndrome at the carpal tunnel and ulnar nerve compression syndrome at the elbow, when these are clinically and electromyographically proven. This test has already been studied in the literature, but the results in terms of sensitivity and specificity are highly disparate. One study has already published negative results on the subject, with the limitation that the trial was monocentric. Through this multicenter study, principal investigator wish to highlight the very probable subjectivity of the SCT when it is performed. As the resistance is applied by the physician's arm, the investigator cannot determine the force applied against the patient, unlike with a measurement object. The principal investigator expects this study to refute the notion that external shoulder rotation force decreases after trigger zone stimulation in cases of proven nerve compression syndrome. The results of this study will thus make it possible to discontinue the use of this technique if it does not help in the diagnosis of compression. The literature shows a lack of prospective, objective studies involving a large number of patients.
- This study will be conducted to answer the following question: Is there a statistically significant effect of chitosan phonophoresis on ulnar nerve conduction velocity, pain level & function in patients with mild to moderate cubital tunnel syndrome? - Fifty-four subjects suffering from mild to moderate cubital tunnel syndrome according to modified McGowan grading system (Palmer & Hughes, 2010) from both sexes diagnosed clinically by electromyography will be recruited for this study. The Age of the participants will range from 20 - 40 years old. Participants with Body mass index between 18.5 and 24.9kg/m2. EMS physio Ltd ultrasound device will be used in combination with chitosan nanoparticles gel. Electrodiagnostic test will be performed for ulnar nerve conduction velocity using Neuropack S1 MEB-9004 NIHON KODEN, JAPAN. Visual analogue scale (VAS) will be used to determine pain level. Quick DASH will be used to determine hand function.Patients will have 3 sessions per week for 5 weeks.
Functional motor recovery distal to a peripheral nerve lesion is predicated upon time to reinnervation of the motor end plate and the number of regenerate axons that reach the target. Supercharged end-to-side (SETS) transfer of the anterior interosseous nerve to the motor fascicle of the ulnar nerve at the level of the distal forearm has been proposed as an adjunct procedure in severe cubital tunnel syndrome to augment motor recovery of the ulnar-innervated intrinsic muscles. Multiple Level IV Therapeutic studies and a systematic review of Level IV Therapeutic studies have reported favorable clinical and electrodiagnostic outcomes following SETS for cubital tunnel syndrome, with low rates of complications. However, in the absence of controls, it remains unclear what proportion of the observed intrinsic motor recovery is attributable to the SETS procedure. The objective of this randomized trial is to compare the results of ulnar nerve decompression with or without SETS for severe cubital tunnel syndrome.
Both simple decompression and anterior transposition of the elbow nerve (ulnar nerve) for acute displaced fractures of the elbow (distal humerus) treated with plate fixation are currently used by surgeons. We want to examine which treatment will overall give better results in regards to arm function and residual pain.
