(1) +/- one year, varies between boys and girl. C-R-I-T-O-E to remember age of ossification. CTE-R-O-I to remember age of fusion (capitellum, trochlea and external (lateral) epicondyle fuse together at puberty. Together they fuse to the distal humerus between the ages of 14-16 years old)
Fracture line is lateral to trochlear groove (less common, elbow is stable as fracture does NOT enter trochlear groove)

An 8-year-old boy falls on his right upper extremity and presents to the emergency room with the radiographs shown in Figures A and B. He has exquisite tenderness to palpation along the lateral aspect of his elbow. What additional radiographic view will likely demonstrate the maximum degree of fracture displacement?
External oblique radiograph
Internal oblique radiograph
Anteroposterior in maximum flexion
Anteroposterior in maximum extension
Lateral in maximum extension
A 36-year-old male presents for evaluation of left hand weakness. A current clnical photograph of his hand is shown in Figure A. His medical history is significant for the elbow injury shown in Figure B, which was treated non-operatively twenty-eight years previously. Current radiographic evaluation of the patients elbow will most likely reveal what deformity?
Avascular necrosis of the lateral fragment
Fishtail deformity of the distal humerus
Fracture nonunion and a normal carrying angle
Nonunion following a pediatric lateral condyle fracture has been associated with which of the following?
Ulnar nerve palsy
Radial nerve palsy
Parsonage Turner syndrome
Restoration of the periosteum alignment in the injury seen in Figures A and B may prevent what complication?
Tardy ulnar nerve palsy
A 7-year-old girl undergoes open reduction internal fixation of a displaced humeral lateral condyle fracture. Dissection around which portion of the fracture fragment should be avoided to protect its blood supply?
