Background: Lunate dislocation is typically caused by direct or indirect traumatic injury to the carpal ligaments. However, other factors can also lead to this condition.
Case Report: A case of a 72-year-old man presenting with lunate dislocation and ulnar nerve compression at the wrist secondary to chronic tophaceous gout. Following proximal row carpectomy combined with ulnar nerve decompression, the patient demonstrated improved wrist pain and mobility, along with reduced numbness.
Conclusion: This is the first reported case of non-traumatic lunate dislocation resulting in ulnar neuropathy secondary to chronic tophaceous gout.
