Management of Displaced Pediatric Radial Neck Fractures Using the Métaizeau Technique

Abstract

Introduction: Radial neck fractures in children are relatively uncommon but can lead to significant functional impairment if not managed appropriately. These fractures often occur between the ages of 8 and 12 and are typically classified as Salter-Harris Type I or II injuries. While minimally displaced fractures can be treated conservatively, displaced fractures pose challenges such as malunion, limited range of motion, and avascular necrosis. The Métaizeau centromedullary technique, a minimally invasive surgical method, has gained popularity for its ability to stabilize fractures while minimizing complications. This case report highlights its effectiveness in treating displaced pediatric radial neck fractures.

Case: A cohort of five children (ages 8–14) with displaced radial neck fractures was treated using the Métaizeau technique. Most injuries were due to falls, with associated fractures present in 31% of cases. Closed reduction was successful in 62.5%, while a lever arm technique and open reduction were used in the remaining cases. Under general anesthesia, elastic intramedullary nails were inserted to stabilize the fracture, ensuring proper alignment while minimizing soft tissue disruption. Postoperative immobilization was maintained for two weeks, with intramedullary nail removal after 2–3 months. Clinical assessment showed that 94% of patients regained full range of motion, with radiological evaluation confirming anatomical healing in 88% of cases.

Conclusion: The Métaizeau technique proves to be a highly effective and minimally invasive method for treating displaced pediatric radial neck fractures. With excellent clinical and radiological outcomes, it minimizes complications while promoting early mobilization. While open reduction remains necessary in select cases, this study reinforces the superiority of closed reduction techniques where feasible. Future research with larger sample sizes and randomized controlled trials will further validate its advantages in pediatric fracture management.
