Background:More than 90% of forearm fractures in children are treated conservatively with good results. Therefore, it is very important to recognize those fractures that cannot be successfully treatedconservatively.Operative management includeeither intramedullary fixation or plates and screws fixation.The aim of the present study was to evaluate short term results of intramedullary fixation for management of diaphyseal forearm fractures in children.Patients and methods:prospective study included 30 skeletally immature patients with forearm fractures who were treated by intramedullary k wires. In all patients, a detailed motor and sensory examination of the ulnar, radial, and median nerves was done to exclude associated nerve injury. Patients were followed up for 6 months.Results: The mean age of was 9.53 ± 2.2years, with the youngest being 6 years and the oldest 14 years. The distribution of the gender in the current study was 25 males (83.3%) and 5 females (16.7%). Regarding the mechanism of trauma; majority of our studied cases (93.3%) bones forearm fractures resulting from falling on outstretched hand (FOOSH), one patient (3.3%) was resulting from road traffic accidents (RTA) and one patient (3.3%) was resulting from directtrauma. Twenty eight patients were right-handed and 2 patients were left handed. The Right side was affected in 22 patients (73.3%) and the left side was affected in 8 patients (26.7%). Majority of fractured bones were middle 1/3 fracture, while five cases were lower 1/3 fracture and only 2 cases were proximal 1/3 fracture.Two cases only had open fracture (6.7%) while the majority of cases had closed fracture (93.3%).Days from injury to operation was ranged from (0) to (5) days with an average of (1.97 ±1.79) days. Majority of our studied cases underwent open reduction (86.79%) while only 4 cases (13.3%) underwent closed reduction of the fractured bones. The patients were assessed three months post operatively using the Outcome Grading System. Twenty two cases (73.3%) showed excellent outcome. Eight cases (26.7%) showed good outcome. No cases with fair or poor outcomes. Conclusion:Intramedullary nailsseems to be safe, more easily not expensive and effective in the management of both bone forearm fractures in children between 4 and 14 years of age.
