A, pear-shaped muscle exercise method:

Extension of the pear-shaped muscle: sitting position, the left leg on the right leg, Erlang leg posture, while the body leaning forward, the arms hold down the knee joint down to the maximum, can reduce the lumbar tension, maintained for 10 seconds, relaxation, retraction, each time 2~3 groups, both sides of the action can be symmetrical.

Second, pear-shaped muscle overview:

1, pear-shaped muscle is distributed in the small pelvis medial, starting from the 2nd to 4th sacral vertebrae in front, through the sciatic foramen magnum, stopping at the top of the femur greater trochanter.

2. It is innervated by the 1st and 2nd sacral nerves and functions to innervate external rotation of the thigh. The shape of the muscle is like a pear, the tendon is long and thin, and above it are the superior gluteal nerve and superior gluteal artery; below it are the pubic nerve, posterior femoral cutaneous nerve, sciatic nerve, inferior gluteal nerve and inferior gluteal artery.

3, pear-shaped muscle itself of various lesions compression of the sciatic nerve, etc. called the pear-shaped muscle syndrome.

Expanded information:

1, the pear-shaped muscle syndrome causes:

(1) hip trauma bleeding, adhesions, scar formation; injections of drugs to make the pear-shaped muscle denaturation, contracture of the fibers; the acetabulum after the upper part of the displacement of the fracture, the bone scab is too large can be made. sciatic nerve compression at the pyriform muscle.

(2) In addition, a small number of patients due to the sciatic nerve out of the pelvis when the path of variation, through the pear-shaped muscle, but the hip external rotation muscle strong contraction, the sciatic nerve can be subjected to excessive pressure, and in the long run to produce the sciatic nerve chronic injury.

2. Clinical manifestations

(1) Pain is the main manifestation of the disease, mainly in the buttocks, and can be radiated to the lower limbs, and in severe cases, they can't walk, or the pain is so severe after walking for a certain distance that they need to rest for a while before they can continue to walk.

(2) Patients may feel the pain is deeper, radiating mainly to the back of the lower limbs on the same side or the back of the lateral side, and some may also be accompanied by numbness of the lateral calf, perineal discomfort, etc. In severe cases, the buttocks appear to be a "hip".
