Acute compartment syndrome of the leg

摘要

Acute limb compartment syndrome is a surgical emergency characterised by raised pressure in an unyielding osteofascial compartment. Sustained elevation of tissue pressure reduces capillary perfusion below a level necessary for tissue viability, and irreversible muscle and nerve damage may occur within hours. Causes include trauma, revascularisation procedures, burns, and exercise. Regardless of the cause, the increased intracompartmental pressure must be promptly decompressed by surgical fasci-otomy. Missed diagnosis and late decompression are associated with significant morbidity due to irreversible ischaemic necrosis of the muscles and nerves in the compartment Increased awareness of the syndrome and the advent of measurements of intracompartmental pressure have raised the possibility of early diagnosis and treatment Recent publications have, however, highlighted some of the problems associated with measurements of intracompartmental pressure. Furthermore, late or poorly performed fasciotomies may contribute to morbidity.
