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 why Mary-Lou’s fracture may take longer to heal than it would for someone who was half her age. In your answer, you are expected to name and discuss three physiological factors that are needed for healing to take place and explain how each of the factors you identified is affected by ageing. Finally, name two complications of hip fracture that are prevalent in the elderly. could you please give me a complete answer to this question with 3 physiological factors explained and also the complication prevalent in elderly Thankyou so much

Answer 1

Dexa scan -3 score show that bone is weak and fragile and osteoporosis conditions

Physiological factor affecting bone healing

1 Age Aftermenopause it's very common in women having calcium deficiency which lead to osteoporosis and

Decrease no of MSC,consequent replace of red marrow by adipose tissue, impaired msc to react with humaoral immunity so reduce osteoblastic response

2 vitamin D lack of hormone and vitamin D dietary intake reduce osteoblastic activity

3.PTH hormones hyperactivity of pth decrease bone density and increase Chance of fracture and delay healing

Complication prevalence

1.hip fracture lead you immobile for long time and cause bed sores

2.blood clot formation occur whenIf a clot breaks off, it can travel to a blood vessel in the lung. This blockage, called a pulmonary embolism, can be fatal.
