Psoas sign - pain with hip extension
It can also present in adute appendicitis
Psoas muscle is located in the lower lumbar region of the spine and extends through the pelvis to the femur. This muscle works by flexing the hip joint and lifting the upper leg towards the body. The patient pain is when he flexes his leg and difficulty/pain when trying to stand in a fully upright posture...also, the question says the infection spread from the lumbar spine ... only flexor in the answer choices is the psoas muscle.
