Abstract

Background: Kirschner wire [K-wire] is commonly used to fix a wrist fracture; however, it may damage the (K-wire) surrounding nerves. Although ulnar‑nerve injury is uncommon, when it occurs, it can lead to symptoms like numbness, tingling, or hand‑muscle atrophy, such as clawing. Sometimes, the complexity of manifestations presents both diagnostic and therapeutic challenges, as encountered in our case, and these symptoms are often overlooked by clinicians. Early detection is vital for effective management and improved outcomes.
Case Presentation: A 59-year-old man presented with intense convulsions in his left forearm and hand, which felt like electric shocks. This distressing sensation was triggered by any movement of his hand, and he reported a strange sensation of having lost his three medial fingers, despite having normal sensations elsewhere. He had been experiencing these symptoms for two years and had been treated with anticonvulsant medications. After surgery, we removed an unusual connection between the nerves, and subsequently the symptoms resolved.
Discussion: It is essential to pay close attention to injuries related to K-wires fixation, especially when they involve the major motor nerves of the hand. Overlooking these injuries can lead to serious consequences.
