Abstract
Background: Melorheostosis is a rare chronic bone disease with a low incidence and unclear pathogenesis, often characterized by pain. It predominantly affects the long bones of the lower limbs and is often treated symptomatically and conservatively.
Case presentation: A 35-year-old female presented with a three-month history of a tumor found in her left wrist joint，leading to limited mobility. There were no obvious abnormalities in laboratory tests. Physical examination indicated a palpable mass measuring approximately 1.0 × 2.0 cm in the left wrist, with limited mobility and no tenderness. Combined with Digital Radiography (DR), the patient was diagnosed with melorheostosis. Surgical intervention involving osteophyte resection was performed on the left wrist joint, resulting in a satisfactory postoperative recovery.
Conclusion: The etiology of melorheostosis remains unclear, presenting with diverse symptoms that can be effectively addressed through surgical intervention.
