Q

With what tool can we do an internal fixation?

A

Tension band fixation
– Less bulky than plates
– Induces compression at the fx site

Intramedullary nail or rod
– For fixation of long bones

Q

What are the general guideline in PT management? (what to “know”)

A

• Know the surgical procedure
• Know the structures involved
• Know your anatomy
– Which muscles/tendons will impact on the Fx site?
• Know & respect the stages of tissue healing
– How long before the Fx is stable enough such that
stressing the fracture site will not impede healing?
• Know the case-related contraindications
• Apply principles of rehabilitation

Q

What are the five clinical presentation signs of an acute fracture

A
  1. Pain – often severe
  2. Paralysis - partial to full loss of ability to move the affected limb / adjacent joints.
  3. Paresthesia – subjective loss of sensation associated with tingling (pins and
    needles, or ‘fourmillement/picotements’ in French). An objective loss of
    sensation may indicate associated nerve damage.
  4. Pallor – the affected limb may appear drained of colour (pale, cyanotic)
  5. Pulselessness - absence of distal pulse, which may indicate associated arterial
    damage

20
Q

Femoral diaphysis fx: what complication can happen (3)?

A

Knee Stiffness, Knee Pain, and Hip Pain

– Limited knee flexion
• ant. scarring of quadriceps (esp. Vast. Intermedius)
• Treatment - aggressive rehab. incl. active knee flexion
– Knee pain → retrograde nails
– Hip pain → antegrade nails

21
Q

Knee radiograph following acute knee-injury if one
or more of:

Age 55 years or older

Tenderness at head of fibula

to avoid equinus contracture

radius + dislocation of distal radio-ulnar joint

37
Q

What is a clavicular middle 1/3 fx can be due to

the pull of the muscles and the arm: primarily the upward pull of the sternocleidomastoid muscle on the medial 1/3 of the bone, combined with the downward pull of the weight of the arm.

38
Q

colle’s fx is whaat?

FOOSH with extended wrist

fracture of the radius, usually within 3cm of the radiocarpal joint, with dorsal angulation and displacement of the distal radius

39

A

garden spade deformity

42
Q

What is a Barton’s fx?

A

intra-articular fracture of the distal radius, with dislocation (or subluxation) of the radiocarpal joint.

Palmar (volar) displacement of the carpals (and fracture fragment) is most common , but dorsal displacement may also occur.

43
Q

What often happen with scaphoid fx?

A

high incidence of non-union and avascular necrosis, due to the poor blood supply to this bone

44
Q

What gives an clinical imprssion of a scpahoid fx?

A

1) Pain in the region of the anatomical snuff box (delineated by the tendons of extensor pollicis longus and brevis, and the radial styloid process).
2) Tenderness to palpation in the anatomical snuff box (slight ulnar deviation of the wrist will make the scaphoid prominent)
3) Pain with axial compression of the 1st metacarpal, while immobilizing the radius
4) While holding the patient’s hand (handshake position), pain in the region of the anatomical snuff box with resisted forearm supination>pronation.

45
Q

What is a bennet fx?

A

base of the 1st MC, in which the fracture line separates the major part of the MC from volar lip fragment, producing a disruption of the 1st CMC (1st MC is pulled proximally by the abductor pollicis longus).

46
