Purpose: One of the most common cause of upper extremity lymphedema is breast cancer surgery. We experienced the nerve entrapment syndrome which was associated with postmastectomy lymphedema. To the best of our knowledge, this is the first case report of lymphedema induced nerve entrapment syndrome on upper extremity in Korea. Methods: A 54-year-old woman presented with a tingling sensation on her right hand, which had been present for 1 year. On her history, she had a postmastectomy lymphedema on her right upper extremity for 20 years. Initial electromyography (EMG) showed that the ampulitude of the median, ulnar, and dorsal ulnar cutaneous nerve were decreased, and conduction block was also seen in median nerve across the wrist. In needle EMG, incomplete interference patterns were observed in the muscles innervated by median and ulnar nerves. In conclusion, electrophysiologic study and clinical findings suggested right median and ulnar neuropathy below the elbow. Therefore, we performed surgical procedures, which were release of carpal tunnel, Guyon's canal, and cubital tunnel. Results: The postoperative course was uneventful until the first two years. The tingling sensation and claw hand deformity were improved, however, the motor function decreased progressively. In 7 years after the operation, patient could not flex her wrist and thumb sufficiently. EMG which was performed recently showed that ulnar motor response was of low ampulitude. Moreover, median, ulnar, dorsal ulnar cutaneous, lateral antecubital cutaneous and median antebrachial cutaneous sensory response were unobtainable. Abnormal spontaneous activities were observed in upper arm muscles. In conclusion, multiple neuropathies were eventually developed at above elbow level. Conclusion: On treating nerve entrapments associated with lymphedema, medical professionals should be fully aware of the possibility of unpredictable results after the surgery, because of the pathophysiologic traits of chronic lymphedema.

We experienced a case of an athlete with a painful mass on the distal peroneal musculature after sports activity, and diagnosed as the entrapment syndrome of superficial peroneal nerve. We treated the case with the mini-open and subcutaneous fasciotomy to release the entrapped peroneal nerve. We report the case with a review of the literature.

Objective : The efficacy of sciatic nerve decompression via transgluteal approach for entrapment of the sciatic nerve at the greater sciatic notch, called piriformis syndrome, and factors affecting the surgical outcome were analyzed. Methods : The outcome of pain reduction was analyzed in 81 patients with sciatic nerve entrapment who underwent decompression through a transgluteal approach. The patients were followed up for at least 6 months. The degree of pain reduction was analyzed using a numerical rating scale-11 (NRS-11) score and percent pain relief before and after last follow-up following surgery. Success was defined by at least 50% reduction in pain measured via NRS-11. To assess the degree of subjective satisfaction, a 10-point Likert scale was used. In addition, demographic characteristics, anatomical variations, and variations in surgical technique involving sacrotuberous ligamentectomy were analyzed as factors that affect the surgical outcome. Results : At a follow-up of 17.5±12.5 months, sciatic nerve decompression was successful in 50 of 81 patients (61.7%), and the pain relief rate was 43.9±34.17. Subjective improvement based on a 10-point Likert scale was 4.90±3.43. Among the factors that affect the surgical outcome, only additional division of the sacrotuberous ligament during piriformis muscle resection played a significant role. The success rate was higher in the scarotuberous ligementectomy group (79.4%) than in the non-resection group (42.6%), resulting in statistically significant difference based on average NRS-11 score, percent pain relief, and subjective improvement (p<0.05, independent t-test). Conclusion : Sciatic nerve decompression is effective in pain relief in chronic sciatica due to sciatic nerve entrapment at the greater sciatic notch. Its effect was further enhanced by circumferential dissection of the sciatic nerve based on the compartment formed by the piriformis muscle and the sacrotuberous ligament in the greater sciatic notch.

Superficial peroneal nerve entrapment is an uncommon compression neuropathy, and is frequently associated with a fascial defect and a muscle hernia. The standard treatment of that was the nerve decompression by complete or limited fasciotomy. But, we experienced a case of superficial peroneal nerve entrapment had satisfactory surgical outcome by fascial repair of peroneus muscle.

This review aims to analyze the efficacy of acupotomy in treating superior cluneal nerve entrapment syndrome (SCNES) by summarizing the findings of randomized controlled trials (RCTs). The RCTs were retrieved from seven databases (i.e., the Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure, Korean Studies Information Service System, Research Information Service System, and Oriental Medicine Advanced Searching Integrated System). Seven RCTs were selected for this review. The results indicate that acupotomy is promising for providing significant pain relief and improving function in patients with SCNES. However, more high-quality RCTs are required to establish the long-term effectiveness and safety of acupotomy. This review provides valuable insights for clinicians and researchers in the management of SCNES.

The pyriformis syndrome is an entrapment neuropathy in which the sciatic nerve is compromised by the pyriformis muscle. Using local anesthetics and steroid injection through a needle guided by an electric nerve stimulator, we satisfactorily treated a case of pyriformis syndrome.

Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the posterior tibial nerve or one of its branches within the tarsal tunnel, and is often caused by ganglia, lipoma, accessory muscles, varicosities, neural tumours, trauma and systemic diseases. We have successfully treated a patient with tarsal tunnel syndrome which was associated with os sustentaculi.

Purpose : To review the operative results and find out better method of a treatment of suprascapular nerve entrapment syndrome caused by ganglion. Materials and Methods : From March of 1996 to May of 2001, thirteen cases of suprascapular nerve entrapment syndrome caused by ganglion were reviewed which were diagnosed using physical examination, EMG and MRI. All of them were treated with open exision of ganglion, nerve decompression and arthroscopic examination. The clinical results were evaluated using subjective recovery of muscle power and ASES (American Shoulder and Elbow Surgeons) score. Results : Nine cases (69$\%$) showed residual symptom such as intermittent pain, insufficient recovery of muscle power, persistent muscle atrophy. Complete recovery in four cases (31$\%$). Mean value of ASES score was 86.4 (70-99.8) points. Postopertively, pain was relieved in 84$\%$ of patients and muscle power was improved in 53$\%$ of the patients but the atrophy persisted. Conclusions : Excision of ganglion is insuffient to relieve the nerve entrapment. Not only excision of ganglion but also treatment of intraarticular lesion, decompression of suprascapular and spinoglenoid notch which attributable to entrapment should be considered for the better clinical results.

The purpose of this study is to suggest a possibility of the Korean medical treatment in patient with anterior interoseous nerve entrapment syndrome. The patient treated with acupunture, herbal medicine and Needle-embedding Therapy from April 19th to May 15th. We measured Visual Analotgue Scale(VAS), and Observed the change in body tempreture using Digital Infrared Thermal Imaging(DITI). After received Korean medical treatment, the patient showed improvement in muscle strength, sensation, VAS, temperature differential. Therefore we can consider Korean medical treatment before operation in interosseous nerve syndrome.
