Crush Injury in the Foot - Compartment Syndrome …

In this injury, the foot is compressed between two hard surfaces, resulting in a "crushing" of bones, soft tissue, and nerves. This often occurs in transportation or occupational accidents, such as if a heavy object falls on the foot, if the foot is run over by heavy machinery, or if the individual is in a car accident.

LisFranc Injury | Orthopaedic Trauma Association (OTA)

Basic Anatomy A "LisFranc" injury is an injury to the joint between the long bones in the foot (metatarsals) and the bones they connect to (tarsal bones). This injury can affect the ligaments (soft tissue that connects bone to bone) of these bones and/or include fractures of the bones themselves. The injury can hurt the whole foot or be limited to part of the foot.

Internal Fixation for Fractures - OrthoInfo - AAOS

Screws at each end of the rod are used to keep the fracture from shortening or rotating, and also hold the rod in place until the fracture has healed. Rods and screws may be left in the bone after healing is complete. This is the method used to treat the majority of fractures in the femur (thighbone) and tibia (shinbone).
