What diseases should be distinguished from pear-shaped muscle syndrome? 1, lumbar disc herniation: this disease often has low back pain with sciatica and compensatory scoliosis deformity of the lumbar spine. Abdominal pressure may aggravate or induce sciatica. The extent of sciatic nerve damage is related to the site of the herniated disc. Straight leg raise test and strengthening test are positive, while 4-character test can be negative; 2. Nerve sheath tumor: High sciatic nerve sheath tumor is less common. Its symptoms are progressive and aggravated, independent of activity or rest. There is a strong Tinel sign in the buttock, but it is difficult to find a localized cord-like tumor, and sometimes it can be found on B
Sometimes a homogeneous thickened echogenic band along the surface of the sciatic nerve can be detected on B-mode ultrasound images, and surgery and pathological examination are the ultimate means to confirm the diagnosis.

If the cause of the syndrome cannot be resolved, heavy scar adhesions are formed or there is bone crust compression or nerve path variation, surgery is required. The outcome of surgery is highly dependent on the duration of the disease.
