Definition
| The piriformus runs horizontally, and the sciatic nerve runs vertically directly beneath the muscle. The piriformis muscle becomes tight and places pressure on the sciatic nerve resulting in leg pain. Often patients confuse pain with pinched nerve pain in lower back. Imaging studies will not show any nerve pinching, but physical exam motion of the hip will generate significant pain. Treatment consists of physical therapy or epidural injections. |

|
Term
|
Definition
| A gait adopted by someone with an absent of weakened hip abductor mechanism. During the step, instead of the pelvis being raised on the side of the lifted foot, it drops. Thus it is seen as the patient's pelvis tilting towards the lifted foot, with much flexion needed at the knee on the affected side in order for the foot to clear the ground. |
|
|
Term
| In Trendelenburg's sign, if your left leg is lifted, which pelvis will drop and which side (left or right) muscle is affected? |
|
Definition
| left leg lifted causes left pelvis to drop, meaning that the right gluteus medius is affected. (left leg up,left pelvis drop, opposite side affected) |
|
|
Term
| A positive Trendelenburg sign is found in: |
|
Definition
subluxation or dislocation of the hip
abductor weakness
shortening of the femoral neck
any painful hip disorder |
|
