The process of reestablishing perfusion can result in further complications due to release of myoglobin, potassium and lactate into the circulation which may result in renal failure, hemodynamic instability, and organ dysfunction. If the pressure is not reduced by incising and opening the fascial compartment to reestablish perfusion, necrosis will occur. This syndrome can occur even if the fracture is open, so the index of suspicion must remain high in this clinical group as well.Ĭompartment syndrome is a constellation of signs and symptoms resulting from an increase in tissue volume within a fascial compartment whose compliance is exceeded once compartment pressure exceeds capillary pressure, ischemia of muscle and nerve within that compartment occurs. Since many patients with tibial fracture are in the first group of young previously healthy individuals, a missed compartment syndrome may have devastating quality-of-life and medico-legal consequences.

Compartment syndrome of the leg can result in permanent disability, ischemic contracture or amputation. It has been reported as high as 14.5% following high energy, complex, bi-condylar tibial plateau fractures. Compartment syndrome is most likely to occur following tibial shaft (up to 8%), followed by tibial plateau fractures (1-2%), although it may also follow forearm, calcaneal, hand, and femur fractures. Tibial plateau fractures with a significant open component and contamination will commonly be treated with external fixation for stabilization with debridement and wound coverage, delaying definitive internal hardware fixation until the infection risk is lower (Figure 2).ģD reconstruction of contaminated (open) lateral tibial condylar and fibular fracture treated with external fixation.Ĭompartment syndrome is an important associated complication following tibial plateau fracture for the anesthesiologist to consider. One recent study showed no difference in infection rate with surgery before or after 6 hours, although no patient developed infection if operated within 2 hours of injury. Conventional management recommends early antibiotic administration and tetanus prophylaxis, and wound coverage within 6 hours, although the data to support a specific time window is lacking. The rate of infection is positively correlated with the extent of soft tissue injury and bone exposure, using the Gustilo classification. The tibia has a relatively poor blood supply and little soft tissue coverage anteriorly, and is more susceptible to infection than other long bones. Open tibial plateau fractures require urgent debridement to reduce infection risk, with soft tissue infection reported in over 20%, and osteomyelitis in over 5% with open tibial fractures. Of course, elderly patients may also have been involved in high velocity motor vehicle or other trauma, and all the aforementioned considerations for trauma patients additionally apply.

A full accounting of medications including anticoagulants is necessary to plan an appropriate regional or general anesthetic, as well as invasive monitoring as indicated. If it was secondary to a syncopal event, then evaluation for cardiac structural or rhythm abnormalities, and cerebrovascular abnormalities may be necessary to address a perioperative risk of stroke. If the tibial fracture occurred from a fall, the history of the fall is important. Rapid evaluation and optimization of medical condition may be needed before operative intervention. Usual preoperative assessment for cardiovascular, pulmonary, hepatorenal, endocrine, neurologic, and musculoskeletal disease in elderly patients applies. The second tibial fracture group of elderly, osteoporotic individuals, present a different set of considerations due to age-related decline in organ function and the presence of medical disease. When a trauma patient presents to the operating room (OR) for ORIF of tibial fracture, the anesthesiologist must be vigilant for signs of traumatic injuries not detected on the primary or secondary trauma surveys. Once the patient is stabilized, attention to the tibial fracture is appropriate. Although fracture management, especially open fracture (see below) is urgent, its management is secondary to the management of truly life-threatening injuries in these patients. The primary “comorbidities” to consider in the otherwise healthy trauma patient are associated traumatic injuries such as head, spine, chest, abdomen and pelvic injuries with potential for occult blood loss, central nervous system (CNS) injury, pneumothorax, great vessel injury, or other organ damage.
