Treatment of Elbow Ulnar Collateral Ligament Injury in a 9-Year-Old Acrobatic Dancer Using Platelet-Rich Plasma

Case: We present the case of a 9-year-old female acrobatic dancer who sustained left elbow dislocation during a routine. Advanced imaging revealed proximal ulnar collateral ligament (UCL) tear. A significant limitation in elbow range of motion (ROM) after initial treatment with an elbow brace and physical therapy prompted a dynamic bedside ultrasound (US) test, which demonstrated persistent instability of the UCL. US-guided injection of platelet-rich plasma (PRP) to the UCL was performed. After PRP treatment, the patient regained complete elbow ROM and a full return to her activity. Conclusion: Platelet-rich plasma can be used as a nonoperative treatment of pediatric elbow UCL injuries.
