Q

A heliotrope rash is present in what condition?

A

Heliotrope rash is caused by dermatomyositis (DM), a rare connective tissue disease. People with this disease have a violet or bluish-purple rash that develops on areas of the skin. They can also experience muscle weakness, fever, and joint aches. The rash may be itchy or cause a burning sensation.

Q

Repeated jumping and landing on hard surfaces causes what injury?

A

Repeated jumping and landing on hard surfaces causes patella tendinopathy or ‘jumper’s knee’. It results in anterior knee pain over 2-4 weeks which comes on with exercise and worsens with jumping.

Q

What is a salter harris fracture?

A

A Salter–Harris fracture is a fracture that involves the epiphyseal plate or growth plate of a bone, specifically the zone of provisional calcification. It is thus a form of child bone fracture. It is a common injury found in children, occurring in 15% of childhood long bone fractures.

Q

SALTR

A
  1. Slipped - fracture plane passes all the way through the growth plate, not involving bone.
  2. Above - fracture passes across most of the growth plate and up through the metaphysis.
  3. Lower - fracture plane passes some distance along with the growth plate and down through the ephphysis.
  4. Transverse - fracture plane passes directly through the metaphysis, growth plate and down through the epiphysis.
  5. Ruined -

crushing type injury does not displace the growth plate but damages it by direct compression.

Q

Green strick fracture

A

A greenstick fracture occurs when a bone bends and cracks, instead of breaking completely into separate pieces. The fracture looks similar to what happens when you try to break a small, “green” branch on a tree. Most greenstick fractures occur in children younger than 10 years of age.

Q

Buckle fracture

A

A buckle fracture, also called a torus fracture, is an extremely common injury seen in children. Because children have softer, more flexible bones, one side of the bone may buckle upon itself without disrupting the other side of the bone—also known as an incomplete fracture—and cause symptoms.

Q

What causes dermatomyositis?

A

Dermatomyositis is usually an autoimmune condition, being most common in women aged 50-70. However, it can also be a paraneoplastic disease, with ovarian, breast and lung tumours being the most common underlying cancers. The possibility of underlying malignancy should be considered, especially in older patients.

Q

Read this summary on lumbar spinal stenosis:

A

Lumbar spinal stenosis is a condition in which the central canal is narrowed by tumour, disk prolapse or other similar degenerative changes.

Patients may present with a combination of back pain, neuropathic pain and symptoms mimicking claudication. One of the main features that may help to differentiate it from true claudication in the history is the positional element to the pain. Sitting is better than standing and patients may find it easier to walk uphill rather than downhill. The neurogenic claudication type history makes lumbar spinal stenosis a likely underlying diagnosis, the absence of such symptoms makes it far less likely.

59
Q

Polymyalgia rheumatica (PMR) is a relatively common condition seen in older people characterised by muscle stiffness and raised inflammatory markers.

A 
Anterior = Dorsiflexion & Inversion
Posterior = Plantarflexion & Eversion

Q

Treatment of an extracapsular NOF?

A
