Chronic Osteomyelitis Caused by Haemophilus parainfluenzae: A Case Report.

Case: A 14-year-old boy presented with a pathologic fracture of the distal aspect of the tibia and a remote history of a dog bite near the injury site. Imaging studies, biopsy, and presentation corroborated the diagnosis of chronic osteomyelitis. Multiple diagnostic methods were negative until an open biopsy identified Haemophilus parainfluenzae, a fastidious oropharyngeal bacterium, with polymerase chain reaction analysis.

Who Gets Compartment Syndrome?: A Retrospective Analysis of the National and Local Incidence of Compartment Syndrome in Patients With Supracondylar Humerus Fractures.

Purpose: Although acute compartment syndrome (ACS) is associated with pediatric supracondylar humerus (SCH) fractures, there are limited data describing its incidence and risk factors. The purpose of our study was to report the local and national incidence of ACS with SCH and floating elbow (concomitant SCH and forearm) fracture patterns and the associated risk factors.

Methods: We retrospectively queried data for SCH fracture patients over a 4-year period from our institution (a level I pediatric trauma center) and the National Trauma Data Bank (NTDB).
