Outcome Measures

Primary Outcomes (2)

Study Arms (2)

Cast immobilization

EXPERIMENTAL

In the casting group, padded synthetic dorsal above elbow and volar below elbow splints are applied in ED without local or general anesthesia. Dorsal displacement and shortening of the radius are not corrected, but the forearm is attempted to be manipulated straight during application of the splints. The casted forearm is then supported by a collar and cuff sling. Splints are removed in an outpatient clinic at 4 weeks. Cast immobilization is discontinued after 4 weeks and when the fracture site is nontender. If palpated tenderness is still present, the patient is given a dorsal forearm splint which can be removed (maximum of 2 weeks usage).

Procedure: Cast immobilization

Percutaneus pinning

ACTIVE COMPARATOR

In the surgery group, a padded dorsal above elbow splint is applied in ED. Reduction and percutaneous pinning are performed under anesthesia in operating room by an experienced attending pediatric orthopedic surgeon within 7 days from the injury. Pin fixation is performed with two 1.6 mm pins. Padded dorsal above elbow and volar below elbow splints are applied. Splints and pins are removed at the outpatient clinic at 4 weeks after surgery.

Procedure: Percutaneus pinning

Interventions

Cast immobilisation is done using finger trap traction. The fractured forearm is splinted above elbow with dorsal cast without attempted reduction.

Cast immobilization

Reduction under fluoroscopic guidance and fixation using two crossing 1.6mm K-wires.

Percutaneus pinning
