A 4-year-old girl sustains a buckle fracture of the ulna and associated radial head dislocation. Closed reduction and immobilization of the arm in 110 degrees of flexion (as swelling allows) and full supination enhances the stability of the injury by which of the following:
Tightening the interosseous membrane
Tightening the biceps
Eliminates plastic deformation
Relaxes the pronator quadratus
Protects the posterior interosseous nerve

A 7-year-old girl falls off of her bike and sustains the injury depicted in Figures A & B. All of the following are indications for surgical management of Monteggia fractures EXCEPT:
Combined radius and long oblique ulnar fracture and reduced radial head dislocation
Incomplete ulnar fracture with lateral radial head dislocation that is successfully reduced
Ulnar communition with ulnar shortening
One week post-reduction/casting radiograph showing loss of radial head reduction
Long oblique ulnar fracture with irreducible radial head dislocation
A 6-year-old boy fell off the monkey bars 3 months ago and has had pain and decreased elbow motion since his fall. His radiographs are shown in figures A and B. Closed reduction was unsuccessful. What is the most appropriate treatment?
Bracing and early range of motion
Closed reduction and casting in supination and flexion
Open reduction internal fixation of medial epicondyle fracture
Open reduction internal fixation of lateral condyle fracture
Open reduction of radial head dislocation with casting in supination and flexion
