AbstractThe calcaneus is the most frequently fractured tarsal bone. Compartment syndrome (CS) complicates fractures and other injuries and is most commonly described in association with the lower leg. The long-term sequelae of CS of the foot can include toe clawing, permanent loss of function, persistent pain, muscle atrophy, contracture, painful warts, weakness, and sensory disturbances. The incidence and clinical significance of untreated CS after calcaneal fractures were questioned. All compliant patients treated by us for a calcaneus fracture underwent a physical examination and medical interview: 47 (49 fractures) were included in the final cohort (36 males, 11 females, mean age 49 ± 14.5 years, mean follow-up 23 ± 16 months). Missed CS sequelae were diagnosed by the presence of claw toes and plantar sensory deficits. The functional outcome and pain at rest and during activity were scored. Five patients (10%) had missed CS, and their functional score was significantly lower than for those without CS (52 ± 21.5 versus 77.4 ± 22 for no CS, p < .05). All missed CS cases were diagnosed in patients with a Sanders type 3 or 4 fracture. Intra-articular fracture was a significant factor associated with developing CS sequelae (p = .045). Untreated CS can cause muscle and nerve injury and contribute to a poor functional outcome. Because CS is more likely to develop after highly comminuted intra-articular fractures, these patients warrant close monitoring for CS development. Early detection and treatment might result in fewer late disabling sequelae of this injury.Copyright © 2013 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.
