18
Q

19
Q

What is injured in Colles fracture

A

Median nerve

  • Carpal tunnel syndrome
  • Weak wrist flexion
  • Loss of thumb opposition
  • Thenar eminence wasting

(Also extensor pollicis longus rupture can occur)

20
Q

What is injured in supracondylar fracture in kids

A

Median nerve (anterior interosseous branch)

Loss of innervation to radial half of flexor digitorum profundus, flexor pollicis longus, pronator quadratus (anterior forearm muscles except ulnar half of FDP)

  • Loss of elbow pronation
  • Unable to do ‘OK’ sign
  • Weak wrist flexion
  • Most common injury seen is weakness in the 2nd finger
21
Q

What is injured in anterior shoulder dislocation

A

Axillary nerve

  • Loss of sensation to ‘regimental badge patch’ area
  • Deltoid and Teres Minor wasting
  • Therefore, weak/lost abduction and external rotation
22
Q

What is injured in olecranon dislocation

A

Ulnar nerve

  • Cubital tunnel syndrome?
23
Q

What can be injured in hip fractures

A

Sciatic nerve

Also: femoral ane pudendal nerves

24
Q

What can be injured in knee dislocation

A

Common fibular nerve

Popliteal artery

25
Q

What can be injured in humeral shaft fractures

A

Radial nerve

  • Loss of sensation over dorsal hand
  • Loss of innervation to extensor (posterior) compartment of forearm - wrist drop
26
Q

What can be injured in tibial shaft fracture

A

Tibial nerve

  • Loss of plantarflexion of ankle and foot
  • Weak inversion
  • Sensory loss to plantar aspect of foot
27
Q

What can be injured in ‘bumper’ injuries i.e. car hitting a pedestrian

A

Common peroneal nerve

  • Foot drop
  • Loss of sensation over dorsum of foot
28
Q

What is a Bankart lesion

A

Tear of glenoid labrum from anterior dislocation

29
Q

What is a Hill-Sachs lesion

A

Cortical depression of posterior humeral head due to posterior dislocation, as head hits off anteroinferior glenoid rim

30
Q

What degree of angulation is allowed for in humeral shaft fracture before surgical intervention is required

A

30 degrees
