What is a classic sign of transient synovitis in children?

• A. Point tenderness
• B. Antalgic gait
• C. Increased temperature in the joint area
• D. Reduction in muscle strength

Answer: (B)

Transient synovitis is a condition commonly seen in children that results from inflammation of the hip joint, often leading to a temporary effusion of synovial fluid. One of the hallmark signs of this condition is the presence of an antalgic gait. This type of gait occurs when a child alters their normal walking pattern to avoid pain in the affected hip.

In children with transient synovitis, the inflammation and associated pain usually lead them to favor their weight on the unaffected leg while the painful hip may not be fully used, resulting in a limp or an awkward gait pattern. This is indicative of their effort to alleviate discomfort while moving.

The other signs mentioned, such as point tenderness, increased temperature in the joint area, and reduction in muscle strength, may indeed occur alongside transient synovitis, but they are not as characteristic as the antalgic gait. The gait change is a direct response to the pain associated with the inflammation, making it a classic clinical observation in assessing transient synovitis in children. Understanding this manifestation can help guide appropriate diagnosis and management.
