Q

What do you see: examine

A
  • Inspection
    • General
      • Note asymmetry
      • Descr scar
      • Arm lymphoedema
      • Evidence of radiotherapy
      • Evidence of axillary clearance / radiotherapy
      • Ask patient to press hips: pec major present?
      • nipple tattoo
    • Flap Reconstruction
      • Scars extend over back or abdominal wall
      • Recess:
        • On back where lat dorsi has been removed
        • In the rectus muscle; ask pt. to lift head of bead (when lying supine) to see recess
    • Implant Reconstruction
      • Rounder shape than normal breast
      • Breast usually lies higher
      • Becker implant may have palpable SC filling port in the axilla

Q
A

Transverse Rectus Abdominis Myocutaneous (TRAM) Flap

  • Pedicled: inf. epigastric A.
    • Or free: attached to internal thoracic A
  • No implant necessary and combined tummy tuck
  • CI if poor circulation: smokers, obese, PVD, DM
  • Risk of abdominal hernia

Q
A

Deep Inferior Epigastric Perforator (DIEP) Flap

  • Evolution of the TRAM flap
  • Free: skin and fat only, no muscle
  • Spares the rectus: ↓ pain and ↓ risk of hernia
  • May not be possible if small perforators

Q
A

Latissimus Dorsi myocutaneous flap

  • Pedicled: skin, fat, muscle and blood supply
  • LD mobilised and tunnelled medially to form neo-breast
  • Supplied by thoracodorsal A. via subscapular A.
  • Often augmented c¯ an implant

Q

Advantages and disadvantages of implants

A
  • advantages:
    • simpler technique
    • primary or delayed
  • disadvantage:
    • cosmetic result not as good
    • requires plenty of available skin
    • lies higher than other breast
    • late comp:
      • capsilar contracture
      • implant leakage
      • infection req removal

Q

myocutaneous flaps advantages and disadvantages

A
  • advantages:
    • useful when little remaining skin or muscle
    • good cosmetic result
    • primary or delayed
  • Disadvantages:
    • increased blood loss
    • increased time of op and complication rate

Q

What is the pathophysiology of dupuytren’s contracture

A

Palmar fascia becomes abnormally thick due to change from type 1 to type 3 collagen, which is significantly thicker

(microvascular ischaemia -> increased xanthine oxidase activity-free radicals-myofibroblast proliferation)

Q

How would you manage Dupuytren’t

C/M/S

A
  • Conservative: splint
  • Medical: radiation, collagenase
  • Surgical: fasciotomy
17
Q

What are your differentials

(2)

A

Ulnar claw; ulnar nerve palsy/volkmann’s ischaemic contracture

18
Q

What is the ulnar paradox

A

The ulnar nerve also innervates the ulnar (medial) half of the flexor digitorum profundus muscle (FDP). If the ulnar nerve lesion occurs more proximally (closer to the elbow), the flexor digitorum profundus muscle may also be denervated. As a result, flexion of the IP joints is weakened, which reduces the claw-like appearance of the hand.[3] This is called the “ulnar paradox” because one would normally expect a more proximal and thus debilitating injury to result in a more deformed appearance.

‘the closer to the Paw, the worse the Claw’.

Decreased sensation

A
20
Q

What do you see?

A

Wasting of the thenar eminence on the left hand

seen in carpal tunnel syndrome due to median nerve palsy

21
Q

Pathophysiology of CTS

A

Flexor retinaculum strong fibrous band covering carpal bones on palmar side of hand Attaches to pisiform and hamate on ulnar side and scaphoid and trapezoid on radial side Ulnar artery, nerve and cutaneous branches of median and ulnar nerves pass on top Median nerve and tendons of muscles that flex the hand run through the carpal tunnel

22
Q

Causes of CTS

(IWRIST)

A

I WRIST

  • Idiopathic
  • Water: pregnancy, hypothyroid
  • Radial fracture
  • Inflammation: RA, gout
  • Soft tissue swelling: lipomas, acromegaly, amyloidosis
  • Toxic: DM, EtOH
23
Q

Management of CTS

(CMS)

A
  • Conservative
    • Splinting
    • Manage underlying cause
  • Medical
    • Steroid injections
  • Surgical
    • Division of flexor retinaculum
24
Q

What is this

A

Split thickness skin graft
