Wading gait is seen in -a) Bilateral dislocation of hipb) Myopathiesc) Common peroneal nerve injuryd) Unilateral dislocation of the hip

**Core Concept**
Wading gait is a type of abnormal gait pattern characterized by a short, shuffling step length and an emphasis on the heel strike, often seen in patients with neurological or muscular disorders affecting the lower extremities. This gait pattern is typically associated with a loss of normal motor control and coordination.

**Why the Correct Answer is Right**
Wading gait is commonly observed in patients with common peroneal nerve injury, particularly those with peroneal nerve palsy. The common peroneal nerve is responsible for innervating the muscles of the anterior compartment of the leg, including the tibialis anterior, extensor digitorum longus, and peroneus longus and brevis. Damage to this nerve can lead to weakness or paralysis of these muscles, resulting in an abnormal gait pattern characterized by a short, shuffling step length and an emphasis on the heel strike.

**Why Each Wrong Option is Incorrect**
* **Option A:** Bilateral dislocation of the hip would likely result in a more severe gait abnormality, such as a Trendelenburg gait or a more pronounced limp, rather than a wading gait.
* **Option B:** Myopathies can cause a variety of gait abnormalities, including a steppage gait or a spastic gait, depending on the specific muscle groups affected, but are not typically associated with a wading gait.
* **Option D:** Unilateral dislocation of the hip would likely result in a more severe gait abnormality, such as a limp, rather than a wading gait.

**Clinical Pearl / High-Yield Fact**
The common peroneal nerve is particularly susceptible to injury due to its superficial location and proximity to the fibular head, making it a common site for compression or trauma.

**Correct Answer: C. Common peroneal nerve injury**
