Trauma — Flashcards

Flashcard 111: Fracture lateral condyle of humerus is classified according to _____ classification

Answer: Milch's

Flashcard 112: Is Bumper fracture an intra or extraarticular #?_____

Answer: Intraarticular

Flashcard 113: The more _____ the fracture is located, the worse is the prognosis for # neck of femur

Answer: proximally (distally/proximally)

Flashcard 114: Stabilization in an infected non-union can be achieved with an _____.

Answer: Ilizarov fixator

Flashcard 115: _____ displacement is more common in supracondylar fracture of the humerus.

Answer: Posterior

Flashcard 116: In forearm #s involving the middle 1/3rd, the position of the cast should be in _____

Answer: mid-pronation

Flashcard 117: Pain in the case of a pathological/stress fracture usually occurs _____ the fracture.

Answer: before (before/after)

Flashcard 118: Among hip injuries, rank the following in descending order of the degree of limb **shortening**: Posterior dislocation, Neck of femur fracture, and Trochanteric fracture.

Answer: 1. Trochanteric fracture (~2 inches / 5 cm) 2. Posterior dislocation (~1 inch / 2.5 cm) 3. Neck of femur fracture (< 0.5 inch / 1.25 cm)

Extra: The degree of shortening depends on whether the injury is intracapsular or extracapsular. In extracapsular (trochanteric) fractures, the muscle pull is not restricted by the joint capsule, leading to significant shortening. Intracapsular (neck) fractures are contained within the capsule, which limits the displacement. Note: Malunited fractures of the femoral shaft can show even greater shortening (up to 3 inches) due to significant overlap of the fragments.

Flashcard 119: In an **anterior hip dislocation**, if the femoral head lies **inferiorly** (over the obturator foramen), it is called the _____ type.

Answer: Inferior (Obturator) type

Flashcard 120: The trough sign is seen in _____ shoulder dislocation

Answer: posterior
