However, the presence of gas inside the medullary canal in the diaphysis of long bones is an uncommon condition, and it is often associated with fractures or previous surgeries. We present the case of a 29-year-old man who suffered an open supraintercondylar femur fracture, treated with debridement, surgical scrub with saline solution, and stabilization by external fixator, and in a second stage with a definitive osteosynthesis, which after being washed with pressure gun presented abundant intramedullary gas non-related to infectious pathology but possibly related to a pulsatile jet lavage during surgery.2017http://zaguan.unizar.es/record/16598710.23937/2572-3243.1510040http://zaguan.unizar.es/record/165987oai:zaguan.unizar.es:165987Journal of Musculoskeletal Disorders and Treatment 3, 3 (2017), 1 - 4byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
