Q

Discuss the portals for a shoulder arthroscopy?

A
  • Posterior portal
    • 2cm inferior and medial of edge of posterior acomium
    • inject with needle into bursa first- easy
    • then new need into joint and aim to coracoid- should inflate and move the needle
    • stab 1cm incsion, trochear towards coracoid avoid humeral head- push the trochar medially
  • Anterior portal- medial of coroacoid- view under direct vision when using knife to widened entry point then remove needle and knife. trochar again aiming slightl lateral .
  • Lateral portal 1 cm lateral form tip of acromium thru deltoid- again using spinal needle and check position directly with arthroscopy camera

Q

What are the contraindications for elbow arthrosocpy?

A
  • Prior trauma
  • sugical scarring
  • previous ulna transposition
    • Ulna nerve subluxation is not contraindication

Q

Decribe the postion of portals in the elbow?

A
  • establish anterior portals with elbow flexed 90o
  • establish posterior portals with som extension
  • straight posterior
    • gd for removing olecarnon osteophytes, loose bodies form posteriomedial compartment
    • 3cm proximal to olecranon, triceps midline
    • injury to posterior antebrachial cutaneous branch andn ulna n
  • direct lateral
    • soft spot portal in traingle formed form olecrnaon, radial head and epicondyle
    • initial site for joint distension before scope inserted
    • see posterior comparmtment
    • realtively safe - lateral antebrachial cutaneous branch
  • Anteromedial- 2cm anterior and 2cm distal to medial epicondyle
  • place under direct vision
  • risk to medial antebrachial cutaneous n and median n
  • never use the posteromedial port due to risk to ulnar nerve

Q

What are the complications of ebow arthroscopy?

A
  • Nerve palsy 1%
    • greatest risk RA, elbow contraction
    • transient ulnar n palsy -common
    • radial n plasy - 2nd common
  • joint ankylosis/Heterophic ossifcation
    • less than open surgery
    • minimise bleeding
  • Infection
    • sinus tract formation- posterolateral port
