Q

Compartment syndrome

A

When the pressure within a compartment increases, restricting the blood flow to the area and potentially damaging the muscles and nearby nerves. It usually occurs in the legs, feet, arms or hands, but can occur wherever there’s an enclosed compartment inside the body.

Q

Clinical features of Compartment syndrome

Q

Compartment syndrome investigations

A

Measure compartment pressure
> <30mmHg is normal
> >40mmHg is high

Compare diastolic arterial and compartmental pressures – the difference needs to be >30mmHg for adequate perfusion

Q

Avascular necrosis

A

A disease that results from the temporary or permanent loss of blood supply to the bone. When blood supply is cut off, the bone tissue dies and the bone collapses. Early complication (within 48 hours of surgery)

Q

What is mal-union?

A

Complication of fractures - the separate areas of bone heal, but with incorrect alignment

Proper placement and reduction of the fracture at the time of injury can prevent it - Significant mal-union can be corrected by osteotomy

Q

Dupuytren’s contracture

A

An abnormal thickening of the skin in the palm of your hand at the base of your fingers. This thickened area may develop into a hard lump or thick band. Over time, it can cause one or more fingers to curl (contract), or pull sideways or in toward your palm.

83
Q

What fingers are usually affected in Dupuytren’s contracture

A

Ring or little finger

84
Q

Pathophysiology of Dupuytren’s contracture

A

Palmar fascia undergoes hyperplasia. Result of contracture and fibrosis of the palmar aponeurosis. Production of abnormal collagen (type 3 instead of type 1)

85
Q

Epidemiology of Dupuytren’s contracture

A
  • Tends to be men
  • Scandanavian/northern European people
  • Associated with diabetes, liver disease, epilepsy
  • Associated with a history of alcohol excess

Q

Clinical features of Dupuytren’s contracture

A

o Tender palpable nodule on palm
o Progressive deformity
o Pain subsides as it progresses
o Contracture of the MCP and PIP joints

88
Q

Management of Dupuytren’s contracture

A
  1. Steroid injections

2. Surgery (Removal of diseased tissue – faciectomy or division of cord – fascioctomy)

89
Q

Posterior hip dislocation

A
  1. Shortening and internal rotation

2. Happens in RTA (where knees hit the dashboard)

90
Q

Anterior hip dislocation

A

Less common

  1. Causes pain in the hip and inability to walk or adduct the leg
  2. Externally rotated – abducted and extended at the hip
91
Q

Shoulder impingement

A

Shoulder impingement is when a tendon in your shoulder rubs or catches on a nearby bone - is a syndrome not a diagnosis

Chronic thickening of the rotator cuff from repeated wear and tear

92
Q

Another name for Shoulder impingement

A

Supraspinatus tendonitis

93
Q

Clinical features of shoulder impingement

A
  • Reaching upwards with the arm exacerbates the pain
  • Painful arc between 50 and 120 degrees - On either side of the arc, it is painless
  • Still full range of movement unlike frozen shoulder
94
Q

Treatment for shoulder impingement

A
  1. NSAIDs
  2. Analgesics
  3. Steroid injections
  4. Physiotherapy
  5. Surgery can be used to make more space
95
Q

Frozen shoulder

A

Shoulder is painful and stiff

96
Q

Frozen shoulder clinical features

A

97
Q

Frozen shoulder management

A
  1. Analgesics

2. Mobilising exercises

98
Q

Difference in shoulder impingement and frozen shoulder

A

99
Q

Rotator cuff tear features

A

  2. Infraspinatus
  3. Teres minor
  4. Subscapularis
101
Q

Difference between full thickness and partial thickness rotator cuff tear

A

Full thickness (active shoulder movement is impossible) or partial thickness (movement is possible but there is pain)

102
Q

Acute calcific tendonitis

A

o Acute onset of severe shoulder pain
o Calcium deposition in supraspinatus
o Self-limiting
o Pain can be eased by needling the lesion

103
Q
