Crush injuries to the lower limbs at a major UK trauma centre: a retrospective observational study.

Purpose: Crush injuries result from the physical compression of muscles and may lead to crush syndrome. Early fluid resuscitation and surgical intervention is key. Few studies have reported the outcomes of crush injuries in the non-disaster setting. This retrospective study aims to characterise such cases.

Methods: Patients with lower limb crush injuries were identified from an internal database. Non-crush injuries and patients under the age of 18 were excluded. Types of injuries, management, and complications were extracted.

Results: 27 patients were included. The right leg (n = 10) was the most frequently injured site. Mechanisms included being run over by vehicles (n = 10) and being crushed by, between, or inside vehicles (n = 8). Fractures were the most common acute injuries (n = 16), while other injuries included rhabdomyolysis, compartment syndrome and degloving. Fluid resuscitation was required in 17 patients. 58 surgeries were performed on 18 patients, with wound debridement and amputations being common. Complications such as acute kidney injury, hyperkalaemia, and sepsis were noted during hospitalisation. Individuals with injuries to the leg or thigh experienced a greater burden of injury and incidence of in-hospital complications compared to those with isolated injuries to the foot.

Conclusion: Crush injuries in the non-disaster setting show distinct mechanisms and injury patterns. Those with crush injuries to the leg or thigh more closely resemble a patient cohort seen in the disaster setting compared to those with isolated foot injuries.
