![]() ![]() Patients at the MA center were more often diabetic (P < 0.05). ![]() Patients at the MA center were more often diabetic (p 0.05). Older children were more likely to have fractures from high-energy mechanisms (45.1% vs. Of those, 160 (18.3%) patients were older than age 8 at time of injury. A consecutive series of 1297 pediatric patients with surgically treated supracondylar humerus fractures was retrospectively reviewed including 873 (67.3%) type III fractures. Baseline demographics, fracture characteristics, mechanism of injury, operative technique, and complications were analyzed. Patients with type III fractures were divided into groups based on age at presentation greater or less than 8. ![]() A retrospective chart review of supracondylar humerus fractures managed at a single level I pediatric trauma institution from 2004 to 2007 was performed. We hypothesized that there would be more complications in older children, reflecting a higher-energy injury mechanism. The purpose of this study was to compare Gartland type III supracondylar humerus fractures in children older than 8 years of age with those in younger children than age 8. Supracondylar humerus fractures are the most common operative fractures in children however, no studies describe the older child with this injury. Increased severity of type III supracondylar humerus fractures in the preteen population.įletcher, Nicholas D Schiller, Jonathan R Garg, Sumeet Weller, Amanda Larson, A Noelle Kwon, Michael Browne, Richard Copley, Lawson Ho, Christine AVN of the trochlea should be considered in patients with late presentation of pain or loss of motion after treatment of supracondylar humerus fractures. Both type A and type B deformities can be clinically significant. In nondisplaced fractures, the lateral vessels are interrupted by tamponade because of encased fracture hematoma this presents as a type A deformity. In displaced fractures, the medial and/or lateral vessels are injured, leading to type A or type B deformity. The cause of this complication is interruption of the trochlea blood supply. AVN of the trochlea has a late clinical presentation. All patients were treated symptomatically. All patients had an asymptomatic clinical period after treatment and re-presented 6 months to 7 years later with elbow pain or loss of motion. ![]() Age at time of injury ranged from 5 years to 10 years. Four patients sustained a Gartland type III fracture, and 1 patient sustained a nondisplaced Gartland type I fracture. Five cases of AVN after supracondylar humerus fracture were reviewed from the Children's of Alabama database. In this article, we present 5 cases of AVN after supracondylar humerus fracture, discuss the importance of late clinical findings, and postulate a mechanism of AVN in nondisplaced fractures. AVN deformity has been classified as type A (AVN of the lateral ossification center) and type B (AVN of the entire medial crista and a metaphyseal portion). Posttraumatic humerus deformity was first reported in 1948 and sporadically thereafter. Avascular Necrosis of Trochlea After Supracondylar Humerus Fractures in Children.Įtier, Brian E Doyle, J Scott Gilbert, Shawn RĪvascular necrosis (AVN) is a rare but important complication after supracondylar humerus fractures. ![]()
