Q

What is the typical presentation of ankylosing spondylitis

A

Young adult male in their 20s with:
Pain and stiffness in the lower back

Q

Investigations for olecranon bursitis

A

Clinical diagnosis
If infection suspected:
Aspiration of bursal fluid and examine fluid:
Pus = infection
Straw-coloured = infection less likely
blood stained = trauma, infection or inflammatory cause
Milky = gout or psuedogout

Microscopy and culture of fluid:
Gram staining for bacteria
Examine for crystals = gout/pseudogout

Q

What is the Trendelenburg test

A

Involves asking the patient to stand one-legged on the affected leg. Normally, the other side of the pelvis should remain level or tilt upwards slightly. A positive Trendelenburg test is when the other side of the pelvis drops down, suggesting weakness in the affected hip.

Q

What is chronic compartment syndrome

A

Usually due to exertion
During exertion, the pressure within the compartment rises, blood flow to the compartment is restricted, and symptoms start. During rest, the pressure falls, and symptoms begin to resolve. It is not an emergency.

Q

What is the additional management for patients on long term steroids? (there is a mnemonic)

A

Don’t STOP:
Don’t – steroid dependence occurs after 3 weeks of treatment, and abruptly stopping risks adrenal crisis
S – Sick day rules (steroid doses may need to be increased if the patient becomes unwell)
T – Treatment card – patients should carry a steroid treatment card to alert others that they are steroid-dependent

Q

Treatment for hip fractures

A

Intracapsular:

internal fixation, or hemiarthroplasty if unfit.

- are not cognitively impaired and
- are medically fit for anaesthesia and the procedure.

Extracapsular:
