In 113 surgically treated children, floating elbow and isolated supracondylar fractures differed in mechanism, fracture type, and nerve injury but showed no detectable difference in elbow function; open floating elbow injuries had more compartment syndrome.
In 52 children with surgically treated supracondylar humeral fractures, the medial collapse sign on postoperative AP radiographs was strongly associated with cubitus varus (sensitivity 90%, specificity 97%) and may flag inadequate medial column reduction.
In 22 children with persistent nerve palsy after supracondylar fracture, ultrasound detected abnormality in 95% but matched operative findings variably, so it should supplement, not replace, clinical judgment in deciding on exploration.
In 298 children with supracondylar humerus fractures, most injuries were simple home falls peaking in summer; prompt closed reduction and pinning gave satisfactory function in 97.9% with minimal complications.
In 60 Gartland III supracondylar fractures, closed reduction and pinning beat open approaches for operative time, union, and cosmesis; among open approaches, anterior did best and posterior worst.
In 450 pediatric supracondylar fractures, only 16% waited beyond 18 hours for surgery; evening ED arrival and high Gartland severity predicted delay, questioning the arbitrary 18-hour quality metric.
A ResNet50 transfer-learning model detected pediatric supracondylar fractures on radiographs with about 90% accuracy, statistically comparable to emergency physicians, but it missed nondisplaced Gartland I fractures and needs prospective validation.
In this prospective EMG study, 26% of neurologically-normal pediatric supracondylar fracture patients had subclinical ulnar or median nerve injury after pinning, with posterior-inferior medial pin placement and longer operative time as key risk factors.
RCT found ultrasound-guided supracondylar radial nerve block gave better pain control than hematoma block during distal radius fracture reduction, with no difference in reduction quality.
Three-screw crossed pinning provides superior torsional resistance and maintains varus stability compared to lateral pinning in supracondylar fractures.
In a synthetic bone model, divergent lateral pins were more stable than parallel lateral pins and comparable to crossed pins in most loading, avoiding ulnar nerve risk; crossed pins resisted rotation best.
Ulnar Nerve Palsies After Percutaneous Cross-Pinning of Supracondylar Fractures in Children's Elbows
In 375 pediatric supracondylar fractures treated with percutaneous pinning, 19 developed postoperative ulnar nerve palsy; all 17 followed recovered fully, sometimes after 4 months, so observation is usually appropriate.
