[Radial head and neck fractures in children].

OBJECTIVE To analyse cases of radial head and neck fractures in children and compare them with the literature. METHOD Retrospective and descriptive study of 21 children with radial head and neck fractures. The following parameters were collected: demographics, comorbidity, classification, treatment, need for rehabilitation, lack of range of motion (ROM), time for recovery and complications. RESULTS The series included 11 males, and the mean age was 8.3 years. The right side was affected in 14 patients. Twelve cases had an associated ipsilateral elbow injury. According to the Chambers classification, 15 cases belonged to group A, while in the Steele-Graham classification, 12 cases were in group I. Eleven patients were treated with immobilization only, 4 percutaneously, and 6 by open reduction and internal fixation (ORIF). Eleven of them needed rehabilitation and despite this, 8 did not achieve full mobility. The mean time to obtain the greatest ROM was 4.71 months. Eight patients had complications, with the most common being neuroapraxia and valgus deformity of the elbow. DISCUSSION AND CONCLUSIONS Treatment of paediatric radius head and neck fractures must be step-wise, from immobilization only, manual and/or percutaneous reduction, to ORIF, whichever is less indicated. In this respect, both the transcapital needle and/or removal the radius head should be avoided. The most common complication is lack of supination, especially in cases treated by ORIF. The posterior interosseous neuroapraxia was the most common of the rest of complications.
