Overview
Radial head fractures and subluxations are common injuries affecting the proximal radioulnar joint, often seen in pediatric populations, with fractures typically diagnosed radiographically and subluxations managed clinically.Diagnosis
Clinical Presentation: Immobile arm, pain, and visible deformity in fractures; palpable click and inability to supinate in subluxations 13.
Radiographic Imaging: Essential for confirming radial head fractures, noting visible fractures or abnormal fat pads 2.
Delayed Diagnosis: High clinical suspicion is crucial; delayed diagnosis can occur despite initial suspicion 2.Management
Reduction Techniques: Both supination-flexion and forced pronation methods are used for subluxation reduction with no significant difference noted in initial success rates 13.
Pain Management: Visual analog scale used for pain assessment during reduction procedures; specific pharmacological interventions not detailed in abstracts 1.
Post-Reduction Care: Most children regain arm use within minutes; prolonged recovery may correlate with younger age 3.Special Populations
Pediatrics: Common injury, with higher incidence in girls and left arm involvement; recurrence rate of 26.7% 3.
Age Considerations: Children under 2 years may experience slower recovery post-reduction 3.Key Recommendations
Utilize either supination-flexion or forced pronation for reduction of radial head subluxation, as both methods show comparable efficacy (Evidence: Moderate 13).
Employ radiographic imaging to confirm radial head fractures, considering abnormal fat pads indicative of injury 2 (Evidence: Moderate).
Monitor pediatric patients closely, particularly those under 2 years old, for prolonged recovery times post-reduction 3 (Evidence: Moderate).References
