Purpose With a prevalence of approximately 3.8% in the general population, carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, posing a global health burden. Compression of the median nerve at the level of the wrist (carpal tunnel) results in dysesthesias, pain, and, in more severe cases, atrophy of median nerve innervated muscles. Essential for the diagnosis of CTS are a precise medical history and clinical examination, including Phalen’s test (maximal flexion of the wrists for one minute) and Hoffmann-Tinel...
Read more Methods and materials Fifteen ultrasound-guided carpal tunnel thread releases were performed on the wrists of soft-embalmed anatomical specimens, which were dissected immediately after the intervention. All study-related procedures were conducted at the Department of Anatomy and Developmental Biology of Karl Landsteiner University for Health Sciences in St. Pölten, Austria, between June and November 2021. The procedures were performed by two musculoskeletal radiologists with 25 and 8 years of experience respectively in interventional radiology. Ultrasound visibility, completeness of transection and damage to surrounding structures...
Read more Results We achieved a complete transection of the transverse carpal ligament in 11 out of 15 interventions (73%) and an incomplete transection in the remaining four (27%). No neural or vascular structures were harmed. In two cases (13%) there was irrelevant damage to flexor tendons. The ultrasound visibility was rough in 5 specimens (33.3%), moderate in 5 (33.3%) and optimal in 5 (33.3%). Essential structures were delineated in all cases.
Read more Conclusion Thread carpal tunnel release only leads to minimal damage to skin, structures within the carpal tunnel and the palmar aponeurosis, promising a low amount of postinterventional complications in the anatomical model. The results may provide a basis for further research and refinement of this technique.
