In a post polio case, ilio-tibial tract contracture is likely to result in :
**Core Concept**
The question tests understanding of the consequences of muscle imbalance and contracture in post-polio cases, specifically focusing on the ilio-tibial (IT) tract. The **ilio-tibial tract**, also known as the iliotibial band, is a ligament that runs down the outside of the thigh from the ilium to the tibia. In post-polio syndrome, muscle weakness and imbalance can lead to contractures.
**Why the Correct Answer is Right**
Since the correct answer options are not provided, let's discuss the general principle. Contracture of the ilio-tibial tract would lead to a deformity characterized by the shortening of this tract, resulting in an abnormal gait and potentially causing the leg to be adducted and flexed, leading to a specific type of gait disturbance.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option details, we cannot directly address why each option is incorrect. However, typically, incorrect options might include unrelated deformities or consequences not directly associated with ilio-tibial tract contracture.
**Clinical Pearl / High-Yield Fact**
In post-polio cases, contractures and deformities are common due to the asymmetric weakness of muscles. The **ilio-tibial tract contracture** can significantly affect the patient's mobility and gait. Understanding the management of such contractures, including physical therapy and potential surgical interventions, is crucial for rehabilitation.
**Correct Answer:** Correct Answer: D. Flexion and adduction deformity of the hip.
