Background:
Calcaneal fractures with open wounds are prone to soft tissue complications. We describe a particular subclass of open injury that occurs on the plantar surface of the foot, medial to the anterior process of the calcaneus, the plantar medial wound (PMW). The purpose of this study was to evaluate soft tissue healing and potential complications in open calcaneal fractures that have a PMW.
Methods:
We established the time to soft tissue healing and the status of the injured limb of 11 adults with 12 calcaneal fractures with a PMW. This was a retrospective review of prospectively gathered data at a Level I trauma center.
Results:
Five fractures developed an infection requiring intravenous antibiotics. Two patients required split thickness skin grafts and 1 patient required a free gracilis flap 10 months after injury to treat a chronic open PMW with resolving osteomyelitis and required a below-knee amputation secondary to flap failure. The most commonly associated bony injury with a PMW was a transcalcaneal-talonavicular fracture dislocation (8/13 injuries). Nonunion of the calcaneal fracture occurred in 3 patients.
Conclusion:
Patients with this type of injury-even those with Gustilo Type I open fractures-need to be apprised that their injury is associated with long-term sequelae, including complications with wound healing, high infection rates, and a higher potential for subsequent amputation than other open hind foot wounds. The Tscherne classification of open wounds should be used in the future.
Level Of Evidence:
Level IV, retrospective case series.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
01:22Burn Injuries
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
