Compartment Pressure Thresholds for Acute Compartment Syndrome in Tibia-Fibula Fractures: A Clinical Consensus and Evidence Synthesis

Acute compartment syndrome (ACS) represents a limb-threatening surgical emergency, frequently associated with closed long bone fractures such as those of the tibia and fibula. The diagnosis of ACS hinges on a combination of clinical findings and objective intracompartmental pressure (ICP) measurements; however, the precise interpretation of ICP thresholds, particularly the debate between absolute pressure values and the delta-P criterion, remains a subject of ongoing clinical contention. This paper synthesizes a clinical discussion originating from a community peer-reviewed platform, involving two expert physicians (Orthopedics & Trauma Surgery, Emergency Medicine) and validated by 46 peer votes, addressing the diagnostic utility of various ICP thresholds, the role of continuous monitoring, and the critical importance of clinical judgment in ACS management. A consensus emerged, strongly advocating for the primacy of clinical findings, such as disproportionate pain and pain on passive stretch, over strict adherence to numerical ICP thresholds. The index case, a 22-year-old male with a closed tibia-fibula fracture, underwent fasciotomy despite a delta-P (diastolic BP - ICP) of 40 mmHg, which typically would not meet traditional surgical criteria. Intraoperative findings confirmed muscle ischemia, and the patient subsequently achieved full functional recovery. Both contributing experts emphasized ICP measurements as an adjunct to clinical assessment and highlighted the significant risks associated with delayed consultation and reliance on an unreliable clinical examination in sedated or obtunded patients. This synthesis underscores that clinical judgment, guided by the classic '5 P's,' should primarily direct the decision for fasciotomy in suspected ACS, even when ICP measurements do not strictly align with established numerical criteria. Timely orthopedic consultation and a heightened awareness of situations compromising clinical assessment are paramount to prevent irreversible ischemic damage and optimize patient outcomes.
