M84.66
Pathological fracture in other disease, tibia and fibula
Clinical Classification Guidelines
Medical Intelligence & Overview
A pathological fracture occurs when a bone breaks in an area that has been weakened by disease or other medical conditions. Specifically, the ICD-10 code M84.66 refers to fractures in the tibia and fibula—two key bones in the lower leg—that occur due to underlying disease rather than typical trauma. This type of fracture often indicates an underlying health issue affecting bone strength, such as osteoporosis, tumors, or infections. Recognizing and understanding these fractures is essential for proper diagnosis and management.
Causes & Symptoms
Clinical Causes: Bone tumors, either benign or malignant, weakening the bone structure Osteoporosis, leading to fragile bones prone to fracture Bone infections such as osteomyelitis, which compromise bone integrity Metabolic bone diseases like Paget's disease Chronic conditions such as rheumatoid arthritis that impact bone strength Prolonged use of corticosteroids or other medications affecting bone density Cancer metastasis spreading to the bones, weakening them
Key Symptoms: Pain localized around the injury site, which worsens with movement or pressure Swelling and tenderness in the lower leg Deformity or unusual angulation of the leg in severe cases Difficulty bearing weight or walking Possible bruising or discoloration around the area Reduced mobility or inability to move the affected leg normally
Diagnostic & Treatment
Diagnosis Path: Diagnosing a pathological fracture involves a combination of clinical assessment and imaging studies. A healthcare provider will review the patient's history of any underlying diseases and perform a physical examination. Imaging tests include:
Treatment Protocols: Managing a pathological fracture typically requires addressing both the fracture itself and the underlying disease causing it. Treatment strategies include:
