M84: Disorders of continuity of bone

M84.4: Pathological fracture, not elsewhere classified

Pathological fracture, not elsewhere classified (M84.4), refers to a broken bone caused by a disease or disorder that has weakened the bone, rather than by a traumatic injury. Astoundingly diverse conditions, such as osteoporosis, bone cancer, or infections, can render bones more fragile and susceptible to fractures under minimal force or stress. The fracture can occur in various parts of the body, however, common sites include the spine, hip, and wrist. Symptoms often include sudden and severe pain at fracture site, limited mobility, and occasionally visible deformity. The development of a pathological fracture could be a sign that the underlying condition has progressed, significantly impacting the health and quality of life of the affected individual. It's important to understand this fracture not merely as an isolated event, but as a potential indication of more systemic issues with an individual's bone health.
