How is a fracture Dx on X-Ray?
2 views, 2 joints, pre- and post-reduction
Radio-lucent line
Cortical disruption
General principles of fracture management?
Analgesia
Wound care
Assessment of VTE risk
Fracture care - Reduction, fixation (open/closed), rehab
Immediate complications fractures?
Pain
Nerve/skin damage
Fat embolus
Soft tissue injury
Early complications of a fracture?
Compartment syndrome
Infection
DVT
Late complications of a fracture?
Stiffness Complex regional pain syndrome Malunion - abnormal position Delayed union - longer than expected Non-union - not healing after expected time

Mx Compartment Syndrome
Fasciotomy, cool and position limb
Analgesia

What is the Gustilo-Anderson Classification of Open Fractures
Type 1: Clean, low energy wound < 1cm
Type 2: 1-10cm, moderate damage
Type 3: >10cm, high energy
What is compartment syndrome?
Pressure in fascial compartment leads to impaired tissue perfusion
Causes of Compartment syndrome?
Burns, fracture haematoma, constrictive bandages, reperfusion syndrome
Pathology - Compartment pressure > capillary pressure
–> Ischaemia –> Oedema and increased pressure –> cycle continues
What are the clinical features of compartment syndrome?
Pain out of proportion
Pain on passive stretching
Palpable tense compartment
Pulselessness - late –> 6Ps ischaemic limb
DDx Compartment Syndrome?
Rhabdomyolysis - High CK, LDH, myoglobin
DVT
Acute limb ischaemia
Septic Arthritis Aetiologies
Haematogenous/Direct spread
S Aureus
Clinical Features Septic Arthritis
Acute onset
Mono-arthropathy
Triad - fever, pain, decreased RoM
Ix Septic Arthritis
US-guided arthrocentesis - WCC >50 - yellow/green - send for biorefringence (gout)
Sepsis 6
Bloods - U&Es (urate)
Urethral, cervical and anorectal swabs - gonorrhoea
