A 12-year-old child presents with tingling sensation and numbness in the little finger and gives a history of fracture in the elbow region 4 years back. The probable fracture is -
Lateral condyle fracture humerus
Injury to ulnar nerve
Supracondylar fracture humerus
Dislocation of elbow
Similar to previous question, the child is presenting with tardy ulnar nerve palsy.
Here the age of child at the time of injury to elbow is 8 years (child is 12 years old and he/she sustained injury 4 years back).
So, age group matches with lateral condyle fracture (5-10 years).
About option 'b'
Ulnar nerve injury due to trauma will present immediately not after 4 years.
