Q

Initial Management of NOF#

A
  • Resuscitate: dehydration, hypothermia
  • Analgesia: M+M
  • Assess NV statur of lumb
  • Imaging: AP and lateral film
  • Prep for theatre:
    • inform anaesthetist and book theatre
    • bloods: FBC, U&E, clotting, x-match (2u)
    • CxR
    • DVT prophylaxis: TEDS, LMWH
    • ECG
    • Films: orthogonal x-rays
    • Get consent

Q

What to look for on imaging of a NOF#

A
  • Ask for AP and lat films
  • look at Shenton’s lines
  • Intra or extracapsular
  • displaces or non-displaced
  • osteopenic

Q

Key anatomy for NOF#

A
  • capsule attaches proximally to acetabular margin and distally to intertrochanteric line
  • blood supply to fem head:
    • retinacular vessels in capsule (distal to proximal)
    • Intramedullar vessels
    • artery of ligamentum teres

if retinacular vessels damaged there is a risk of AVN of fem head -> pain, stiffness and OA
