Which describes the pathology of immune thrombocytopenia?

Choice A reason:

Releasing traction every hour to perform skin care: Releasing traction every hour is not recommended as it can disrupt the alignment and healing process of the fractured femur. Skin care is important, but it should be performed without compromising the traction setup.

Choice B Reason:

Releasing traction once every 8 hours to check circulation: While checking circulation is crucial, releasing traction every 8 hours is not necessary and can interfere with the therapeutic benefits of traction. Circulation can be monitored without releasing the traction.

Choice C Reason:

Maintaining continuous traction until 1 hour before the scheduled surgery: Continuous traction is essential to maintain the alignment of the fractured femur. However, there is no need to release traction 1 hour before surgery unless specifically instructed by the surgical team.

Choice D Reason:

Maintaining continuous traction and checking the position of traction: This is the most appropriate action. Continuous traction ensures proper alignment and healing of the fractured femur. Regularly checking the position of traction helps prevent complications and ensures the effectiveness of the treatment.

The correct answer is a) Positive Ortolani click, b) Unequal gluteal folds, c) Trendelenburg sign, and e) Telescoping of the affected limb.

Choice A reason:

A positive Ortolani click is a clinical manifestation of developmental dysplasia of the hip (DDH). The Ortolani maneuver is used to detect hip dislocation or subluxation in infants. When the hip is abducted and gentle pressure is applied to the proximal thigh from behind, a palpable “clunk” is noticed as the femoral head relocates into the acetabulum. This indicates hip instability, which is a characteristic of DDH.

Choice B reason:

Unequal gluteal folds are another clinical manifestation of DDH. Asymmetrical gluteal creases can suggest hip dysplasia in infants. This is because the dislocation or subluxation of the hip can cause one leg to appear shorter than the other, leading to uneven gluteal folds.

Choice C reason:

The Trendelenburg sign is a clinical test used to assess the integrity and strength of the hip abductor muscles, particularly the gluteus medius and gluteus minimus. A positive Trendelenburg sign usually indicates weakness in these muscles, which can be associated with hip abnormalities such as congenital hip dislocation3. In DDH, the hip instability can lead to a positive Trendelenburg sign.

Choice D reason:

A negative Babinski sign is not a clinical manifestation of DDH. The Babinski reflex is a normal reflex in infants up to 2 years old, where the big toe moves upward and the other toes fan out when the sole of the foot is stroked. A negative Babinski sign would indicate the absence of this reflex, which is not related to DDH.

Choice E reason:

Telescoping of the affected limb is a clinical manifestation of DDH. In a child with DDH, the hip socket is shallow, and the head of the femur may slip in and out, leading to a telescoping effect. This means the femoral head can move further out of the socket, causing the limb to appear shorter or longer depending on the position.
