What is the etiology of cubitus varus following a supracondylar humerus fracture in a child?
Overgrowth of the lateral physis
Malreduction of the fracture
Growth arrest of medial physis
Injury to the ulnar nerve
Radial head dislocation
A 7-year-old boy falls off the playground and sustains the injury shown in figure A. What motor deficit is associated with the nerve most commonly injured in this fracture pattern?
Weakness of the flexor digitorum profundus to the index finger
Weakness of the extensor pollicis longus
Weakness of the flexor pollicis longus
Hand intrinsic weakness
The most common nerve injured in the fracture shown in Figure A innervates all of the following muscles EXCEPT?
flexor digitorum profundus index finger
flexor digitorum profundus middle finger
flexor pollicis longus
extensor pollicis longus
Which of the following elbow apophyses is the last to fuse during growth?
External (lateral) epicondyle
Internal (medial) epicondyle
A child falls off of the monkey bars at school and sustains the left elbow injury shown in Figure A. What is a disadvantage of the fixation construct shown in Figure B compared to Figure C for this injury pattern?
Less biomechanical stability
Higher incidence of compartment syndrome
Higher chance of osteomyelitis
Higher risk of iatrogenic injury to the ulnar nerve
Higher risk of iatrogenic injury to the anterior interosseous nerve
Following successful operative treatment, routine removal of hardware is recommended at 3-4 weeks for which of the following procedures?
A 10-year-old boy sustained the injury shown in figure A while jumping off a trampoline. His hand is pulseless and cold. What is the next step in management?
Loose-fitting splint application and reassess in 1 hour
Emergent closed reduction and pin fixation
Open vascular exploration
Forearm skeletal traction pin
A 7-year-old patient presents with a fracture of her left supracondylar humerus and distal radius as evidenced in Figure A. She is neurovascularly intact and the skin shows no evidence of open wounds. Radiographs of the elbow show a displaced supracondylar fracture. Radiographs of the wrist show an extra-articular distal radius fracture with 25 degrees of dorsal angulation. This injury is most appropriately treated with which of the following?
Closed reduction and casting of the supracondylar humerus fracture and distal radius fracture
Closed reduction and pinning of both the supracondylar humerus fracture and distal radius fracture
Closed reduction and casting of the supracondylar humerus fracture and pinning of distal radius fracture
Open reduction and pinning of both the supracondylar humerus and the distal radius fracture
Closed reduction and pinning of the supracondylar humerus fracture and closed reduction and casting of distal radius fracture
A 5-year-old boy sustains a type II (Gartland classification) supracondylar fracture which is treated with cast immobilization. Healing results in a mild gunstock deformity. Surgical treatment of this will most likely result in:
improved functional outcome
improved pain relief
improved range of motion
reduce non-union rates
What is the advantage of medial and lateral crossed pins compared to two lateral pins in the treatment of supracondylar humerus fractures?
Greater ultimate clinical arc of elbow motion
Lower revision rate
Lower incidence of ulnar nerve injury
Greater experimental biomechanical stability
More anatomic fracture reduction
A 8-year-old boy has a cubitus varus deformity of his left elbow after a supracondylar humerus fracture was treated in a splint. What is the most common cause of this deformity?
Malreduction causing malunion
Medial epicondyle growth arrest
Lateral condyle overgrowth
Medial epicondyle avascular necrosis
Unrecognized compartment syndrome

Lateral entry percutaneous pinning of a SCH fx
HPI - 7 year old male patient. Presented with history of supracondylar fracture of Left elbow 5 months ago. ORIF was performed and removal of K-wires done after 2 months. Physiotherapy done after surgery, but with little benefit and minimal improvement of ROM.
How can we obtain better elbow motion for this patient?
HPI - Witnessed fall from ladder while at school.
What is your preferred management of this case?
HPI - Child age 8 sustained supracondylar fracture on 20 July 2015, admitted in Hospital and urgently operated. Due to lack of C arm in operation theatre doctor didn't check fracture position and somehow decided not to reoperate later when he confirmed position of fracture by x rays.
