An eight years old child is suffering from transient synovitis of the hip joint. Which of the following statement is false
**Core Concept**
Transient synovitis of the hip joint is a benign condition characterized by inflammation of the synovial membrane, often occurring in children. It is a self-limiting condition that typically resolves with rest and conservative management.
**Why the Correct Answer is Right**
The hip joint in transient synovitis is typically held in flexion, abduction, and external rotation due to pain and discomfort. This position helps to minimize tension on the inflamed synovium. The flexion and abduction position allows the child to assume a position of comfort, while the external rotation helps to reduce the pain and discomfort associated with the condition. The characteristic position of the hip joint is a key clinical feature that helps in diagnosing transient synovitis.
**Why Each Wrong Option is Incorrect**
**Option A:** Transient synovitis of the hip joint often follows a viral upper respiratory tract infection, which can trigger the inflammatory response in the synovial membrane.
**Option B:** WBC count and ESR are usually normal in transient synovitis, as the condition is primarily a self-limiting inflammatory response without significant systemic involvement.
**Option D:** Widening of the joint space will be seen on ultrasound due to the accumulation of fluid in the joint, which is a characteristic feature of transient synovitis.
**Clinical Pearl / High-Yield Fact**
Transient synovitis is a clinical diagnosis based on a combination of clinical features, including the child's age, the presence of hip pain and stiffness, and the characteristic position of the hip joint. It is essential to differentiate transient synovitis from other conditions, such as septic arthritis, which requires prompt medical attention.
**✓ Correct Answer: C. The hip is typically held in adduction and internal rotation**
