Piriformis syndrome is a syndrome of low back and leg radiating pain thought to be due to a chronic contracture of the piriformis muscle that causes irritation of the sciatic nerve. The piriformis muscle is a flat pyramidal muscle, an external rotator and abductor of the hip, originating from the front of the sacrum and inner aspect of the sacroiliac joint, then passes laterally out of the sciatic notch to attach posteriorly to the greater trochanter of the femur, the sciatic nerve passes between the two bellies of the muscle. Mechanical irritation of the sciatic nerve by an inflammatory reaction of the piriformis muscle and its fascia at this pelvic level causes pain to radiate in the dermatomal regions of the nerve roots similar to that disk entrapment. diagnosis of piriformis syndrome is made primary on the basis of history and clinical examination. The incidence is considerably higher in women, with the reported ratio of women to men of 6:1. These patients frequently present with associated symptoms of pelvic pain and/or dyspareunia. Symptoms are usually unilateral but occasionally be bilateral. We had a 42 year-old woman patient with low back and left leg radiating pain and dyspareunia treated by caudal steroid and local anesthetic.

The upper trunk of the brachial plexus is the most common area affected by neuralgic amyotrophy (NA), and paresis of the shoulder girdle muscle is the most prevalent manifestation. Posterior interosseous nerve palsy is a rare presentation in patients with NA. It results in dropped finger on the affected side and may be misdiagnosed as entrapment syndrome or compressive neuropathy. We report an unusual case of NA manifested as PIN palsy and suggest that knowledge of clinical NA phenotypes is crucial for early diagnosis of peripheral nerve palsies.

There are various origins for chronic abdominal pain. About 10-30% of patients with chronic abdominal pain have abdominal wall pain. Unfortunately, abdominal wall pain is not thought to be the first origin of chronic abdominal pain; therefore, patients usually undergo extensive examinations, including diagnostic laparoscopic surgery. Entrapment of abdominal cutaneous nerves at the muscular foramen of the rectus abdominis is a rare cause of abdominal wall pain. If abdominal wall pain is considered in earlier stage of chronic abdominal pain, unnecessary invasive procedures are not required and patients will reach symptom free condition as soon as the diagnosis is made. Here, we report a case of successful treatment of a patient with abdominal cutaneous nerve entrapment syndrome by ultrasound guided injection therapy.

Tarsal tunnel syndrome is a complex of symptoms resulting from the compression of the posterior tibial nerve or its branches, Many disease have been previously reported in the literatures as etiological agents in tarsal tunnel syndrome. We reported a case of tarsal tunnel syndrome secondary to neurilemoma of the first branch of lateral plantar nerve. The symptoms were similar with the entrapment syndrome of the first branch of the lateral plantar nerve. Symptoms were completely relieved after operation.

This study was performed to investigate the cause, symptom, treatment of carpal tunnel syndrome through Western medicine and Dong-Eui-Bo-Kham(東醫寶鑑). Results & conclusions 1. Carpal tunnel syndrome is a common peripheral nerve entrapment syndrome that is characterixed by pain, numbness, sensory disturbance along the dsitribution of the meridian nerve in hand 2. Treatment of carpal tunnel syndrome have included wrist immobilization, anti-inflammatory drug, local injection of steroid, nerve block and surgical decompression. 3. Carpal tunnel syndrome seems to be similar with numbness(痺證). The causes were usually pathogenic Wind, Cold, Dampness. 4．Acupuncture, herbal medicine, herbal acupuncture were used for treatment of carpal tunnel syndrome. We considered that more study to find various and effective methods oriental medicine for carpal tunnel syndrome should be made.

Recurrent motor branch entrapment syndrome is a compressive mononeuropathy of recurrent motor branch of median nerve. It is a rare condition as a cause of thenar muscle wasting and may have different pathogenesis. If such an anatomical variation is the cause, there is a possibility that thenar muscle atrophy remains if only the transcarpal ligament release is performed. We report a 25-year-old male patient with carpal tunnel syndrome with thenar muscle wasting 1 month ago.

Purpose: Soft tissue chondroma is a rare benign tumor, found mainly on the palm and sole and grows slowly. Typically, mature hyaline cartilage is the dominant pathological feature. There are reports that assert soft tissue chondromas to be a cause of median nerve entrapment syndrome. However, this is the first case report showing soft tissue chondroma to be a cause of simultaneous median and ulnar neuropathy. Methods: A 62 year-old woman presented with chief complaints of numbness and hypoesthesia of her right palm for 4 to 5 years, and a palpable mass on her right palm that had been increasing in size slowly for 3 years. Physical examination revealed a firm, mobile, non-tender and about $3{\times}3\;cm^2$ sized mass in the center of the right palm. Electromyography showed entrapment neuropathy of the median and ulnar nerve. Ultrasonography showed an approximately $5.7\;cm^2$ mass below the flexor tendon of ring finger. Upon surgical excision, a $3{\times}3\;cm^2$ mass attached to the flexor digitorum profundus of ring finger and redness and hypertrophy of both the median and ulnar nerve were discovered. Mass excision was performed gently and the specimen was referred for histopathologic study. Mass excision resulted in median and ulnar nerve release. Results: The pathology report confirmed the mass to be a soft tissue chondroma with mature hyaline cartilage. The patient exhibited post-operative improvement of her symptoms and did not show any complications. Conclusion: This is the first case report showing soft tissue chondroma to be a cause of simultaneous median and ulnar neuropathy.

Posterior interosseous nerve(PIN) syndrome is an entrapment of the deep branch of the radial nerve just distal to the elbow joint. It is caused by acute trauma or masses compressing the nerve. We report an unusual case of PIN syndrome with wrist drop caused by compression of the nerve by anomalous vascular leash. The patient has recovered with the surgical decompression of the offending vessels and arcade of Frohse.
