More Than Just Another Elbow Tendinopathy: A Case Series of Misdiagnosed Ulnar Nerve Compression and Review of Common Upper Extremity Misdiagnoses in Climbing.

Abstract: Climbing is an increasingly popular sport. Yet, we have encountered numerous misdiagnosed climbing injuries, highlighting a gap in climbing-related literature and a need for heightened awareness within the sports medicine community. We present a case series that highlights the clinical manifestation of ulnar nerve entrapment and compression in three patients with initially misdiagnosed and mismanaged elbow tendinopathy. After a correct diagnosis of ulnar nerve pathology was made, each patient underwent a prescribed rehabilitation protocol that focused on nerve motility exercises (tensioning and flossing), resulting in a significant reduction in pain and a successful return to their pre-injury climbing performance. We thus aim to raise awareness of this often-mistreated presentation. Furthermore, we highlight other common upper extremity climbing misdiagnoses and provide relevant clinical recommendations to accurately identify and manage such injuries in climbers.
