Melorheostosis

ICD-10 Code
Q78.8_1

Rare dysplasia causing thickening of the cortical bone resembling "dripping candle wax" on x-rays.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with chronic, progressive localized bone pain, stiffness, and restricted range of motion in the affected limb. History of soft tissue contractures or limb length discrepancy noted. Symptoms are often exacerbated by activity. No history of acute trauma; pain is described as deep, aching, and persistent.

Clinical Examination Findings

Physical examination reveals palpable, hard, non-tender bony protuberances along the affected bone segments. Joint examination demonstrates significant limitation in range of motion (ROM) due to periarticular ossification or soft tissue contractures. Skin overlying the lesion may appear thickened or show sclerodermatous changes. Neurological exam is intact unless secondary nerve compression is present.

Treatment Protocol

Management is primarily symptomatic and multidisciplinary. Options include physical therapy for ROM maintenance, analgesics (NSAIDs) for pain management, and bisphosphonates in selected cases. Surgical intervention (osteotomy, tendon lengthening, or excision of bony overgrowth) is reserved for severe functional impairment or significant deformity. Regular monitoring for progression and secondary complications is required.
