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.

Ques 5- Discuss the pathophysiology of the condition causing the crepitus Mary-Lou is experiencing in her joints. In your answer, list at least two more signs and symptoms associated with the disease.

Ques 6- 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

Ques 5- Discuss the pathophysiology of the condition causing the crepitus Mary-Lou is experiencing in her joints. In your answer, list at least two more signs and symptoms associated with the disease.

Ans: PATHOPHYSIOLOGY OF CREPITUS:

Crepitus is a commom sign of a bone fracture. Crepitus can easily be created and obseved by erecting a small amount of force on a joint, thus cracking it . This is caused by bubbles of Nitrogen forming in the synovial fluid bursting.

* The term crepitus is sometimes also used to describe other conditions, such as lungs crackling from respiratory illnesses and bones grating after fractures.

SIGNS AND SYMPTOMS OF CREPITUS :

A) Joint popping or crackling.

B) Crackling or grinding sounds or a crunching sensation when you move your shoulders.

C) Occasional or continual swelling around the joints.

Q6)  Discuss how the aetiology of Mary Lou’s joint disease differs from the other joint disease we covered in BIOL122. (5 marks) other disease we covered were fracture, osteoarthritis, osteoporosis. is it possible to DM me the answer.

Ans : As joint pain to Mary Lou's was due to degeneration of her cartilage and this could be due to the crepitus which causes problem in the joints such as hip, shoulder, neck and spine.

While arthritis could br due to the ageing process and sometimes joint problems could be due to the Auto Immune Disorder.

But Crepitus could be related to other problems also because degeneraion of cartlage could occu in all joint problems.
