Volkmann’s Ischaemic Contracture results from an elevation of interstitial pressure in a closed osseo-fascial compartment that leads in micro vascular compromise and irreversible damage to the contents of the space.
Aetiology of Volkmann’s Ischaemic Contracture:
1.Decreased compartment size.
Closing of fascial defects
Localised external pressure
2.Increased compartmental content
3.Increased capillary permeability
Burns, trauma, post exercises, seizures, intra arterial drugs, exercise, venous obstruction.
4.Increased Capillary Pressure
Exercise, Venous Obstruction
External or Internal Constrictions, trigger an arterial spasm or occlusion which in turn leads to muscle ischaemia and increased capillary permeability.
Increased capillary permeability results in intramuscular oedema, increase in intra muscular pressure – this worsens already existing arterial compromise.
Muscle finally undergoes necrosis and necrosed muscle tissue is replaced by collagen, manifesting as contractures.
Impending signs of Volkmann’s Ischaemic Contracture:
6.Positive Passive Stretch Test.
Management of Volkmann’s Ischaemic Contracture:
Excision of Affected Muscle
Max Page’s muscle sliding operation
Excision of cicatrix
Excision of Sac
Arthrodesis in functional position
Amputation if excessive gangrene is present.
