Definition
Acute Compartment Syndrome occurs when
there is elevated pressure in a closed fascial
(osteofascial) space, resulting in a critical
reduction of blood flow to the tissues
contained within.

Historical Review
Late complications of ischaemic
contracture
Volkman, 1881
Paralysis and ischaemia, too-tight
bandaging of the forearm and
hand,arterial blockage and
irreversible contracture.
Leser 1884 - animal studies
Brooks 1922 - venous obstruction
Griffiths 1940 - Pain with.. , Painful onset,
Pallor, Puffiness
Bardenheuer 1911 - fasciotomy forearm
Whitesides, Hargens and Mubarak, and
Matsen 1970’s - tissue pressure
measurement techniques.
Current - sustained microcirculatory
impairment,
Still occurs. Not uncommon

Pathophysiology
Normal tissue pressure
0-4 mm Hg
8 - 10 mm Hg with exertion
Absolute compartment pressure theory
30mmHg - Mubarak and Hargens
45 mmHg - Matsen
AV gradient theory
LBF = Pa - Pv / R
<30mmHg diastolic pressure
‘do not elevate arm’
Microvascular occlusion theory

Syndrome
Tissue Survival
Muscle
3 - 4 hrs = reversible damage
6 hrs = variable damage
8 hrs = irreversible damage
Nerve
2 hrs = loose nerve conduction
4 hrs = Neuropraxia
8 hrs = irreversible damage

Surgical treatment
Principles
Early diagnosis
Long extensile incision
Release all fascial
compartments
Preserve neurovascular
structures
Rigid fracture stabilisation
Debride necrotic tissues
Cover 7-10 days
