EXP:

  • There is no doubt about option ‘a, c & e’.
  1. Lateral condyle fracture is Salter Harris type IV injury.
  2. Tardy ulnar nerve palsy is a known complication, especially after malunion (cubitus valgus).
  3. In displaced fracture, open reduction and internal fixation is indicated.
  • Option ‘b & d’ require explanation here.
    Option ‘d’
  1. Lateral condylar spur formation is the most common deformity after a fracture involving the lateral condylar physis. It is caused by coronal rotation of distal fragments which tends to displace a flap of periosteum laterally. This periosteum then produces new bone formation in the form of a spur.
  2. Due to this overgrowth on lateral side, elbow looks into varus. It is called pseudovarus as it is not true cubitus varus but gives its appearance.
  3. So, option `0:1’ is partially correct.
  4. However, you should keep in mind that cubitus valgus is much more common than true cubitus varus in fracture lateral condyle humerus.

Option ‘b’

  • The most common complication after surgery is lateral spur (pseudovarus).
  • Lateral spur occurs after both nonoperative and operative treatment.
  • It results from extensive dissection at the time of operation, which causes hypertrophic bone formation.
