In order to diagnose the cause of chronic low backache in a 55-year-old woman, it's important to consider the common conditions that could contribute to this symptom:
Osteoporosis: A condition characterized by weakened bones, increasing the risk of fractures. It is common in postmenopausal women due to decreased estrogen levels, which affect bone density. Chronic back pain in this context is often due to vertebral fractures.
Hurler's Syndrome: A rare genetic disorder that presents early in life with a variety of symptoms including skeletal abnormalities. It's unlikely to be newly diagnosed at this age.
Paget’s Disease: A disorder involving abnormal bone remodeling, which can cause bone pain, deformities, and fractures, but is less common and symptoms often present in specific areas.
Renal Osteodystrophy: Bone disease related to chronic kidney failure with mineral imbalances; back pain could occur but is linked with kidney disease history.
Given that this is a 55-year-old woman, the most likely diagnosis, considering the prevalence and characteristic symptom of low back pain, is Osteoporosis.
