Question

Mary-Lou’s family was happy with the management plan established by the doctor as Mary-Lou was progressing quite well. She was using notepads to jot down reminders, a pillbox to keep her medication organized and a calendar to record appointments. Her family members were helping her with routine tasks such as cooking and paying bills. She was feeling much happier and did not have to rely on alcohol to go to sleep. On one particular day she was feeling so good she decided to walk to her GP appointment alone. On her way there she stumbled over a branch and fell. She felt excruciating pain in her hip. A passer-by called an ambulance and she was taken to the emergency department at the Royal Melbourne hospital. An X-ray revealed that she had broken the neck of her femur and had to have surgery to repair it. Mary-Lou wondered whether this was linked to the crepitus she had been experiencing in her joints. Her joints did feel quite stiff and painful lately. The specialist explained to Mary-Lou that the crepitus was likely due to degeneration of her cartilage and said that the fracture might have been due to weakened bones. He told her he would like her to have a bone mineral density test to measure her bone density. The DEXA scan gave a T-score of -3.0. Mary-Lou is now given bisphosphonates and told to increase her daily intake of calcium.

Discuss how the aetiology of Mary Lou’s joint disease differs from the other joint disease we covered in BIOL122. other disease we covered were fracture, osteoarthritis, osteoporosis. is it possible to DM me the answer. Thankyou

Answer 1

Answer: The aetiology of Mary Lou’s joint disease differs from the other joint diseases like fracture, osteoarthritis, and osteoporosis in many ways. A general fracture is caused due to mechanical collision or an external physical stress. Osteoarthritis is the most common type of arthritis which occurs when the protective cartilage that cushions the ends of the bones wear down over time. Osteoporosis is the weakening of bones because the creation of new bone does not keep up with the loss of old bone. The development of porous bone due to osteoporosis can lead to fracture. The T-score of Mary Lou’s is -3.0, that indicates severe osteoporosis. The bone density has decreased causing the bones more likely to be fractured. Bisphosphonates is administered to help in jing the fractured bone. Calcium intake make the bone stronger.
