Most of Danis-Weber type B fracture has an oblique fracture plane proximal posteriorly to distal anteriorly. In these cases, the lateral plate has become widely accepted. However some limitation to the use of the lateral plate exist. The plate must be bent accurately and the screws in the distal fragment must be unicortical to avoid penetration into the joint, predisposing it to poor fixation in the osteoporotic bone. In 1982, Brunner and Weber introduced the antiglide plate for fixation of the shaft oblique fracture of the distal fibula, but it has not widely used. The author reviewed 21 cases treated by antiglide plate fixation from March, 1995 to March, 1999 which could be follow-up more than 1 year. We analysed the result radiographically and clinically using Ankle-Hindfoot scale(100 % total) of the American Orthopedic Foot and Ankle Society. The results obrained were as follows: 1. All fracture were united at average 8 weeks clinically and radiographically. 2. According to the Ankle- Hindfoot scale, 8 cases were above 90 points, 11 cases were beet ween 80 and 89 points and two cases were below 80 points. 3. One case had an injury to intermediate dorsal cutaneous nerve.

Purpose: The purpose of this study is to report the result of endoscopic assisted curettage and bone graft for the treatment of simple bone cyst in the calcaneus. Materials and Methods: Three cases in three patients who had curettage and bone graft of simple bone cyst in the calcaneus under endoscopic view were prospectively reviewed. A minimum follow-up of 1 year was required for entrance into the study. The results of treatment were clinically and radiologically assessed. Results: One case with preoperative heel pain gained complete relief of the pain at postoperative four weeks. All three cases had radiological union of grafted bone at an average of thirteen weeks after the operation. Shortened hospitalization and decreased postoperative pain were remarkable. Complications such as infection, skin necrosis, nerve injury, and, fracture were not seen. There was no evidence of the recurrence of the cyst in all three cases. Conclusion: Endoscopic assisted curettage and bone graft of simple bone cyst in the calcaneus is thought as an effective alternative procedure avoiding the possible complications of the classic method.

Purpose: To report the clinical outcomes and complications of flexor hallucis longus (FHL) tendoscopy using 3 portals. Materials and Methods: Between January 2012 and April 2013, 10 patients (10 ankles) received tendoscopic surgery for the treatment of FHL tenosynovitis. Patients complaining of pain and tenderness along the course of FHL despite over 6 months of conservative treatments were indicated for surgery. The mean age was 41.7 years (range: 18-57) and the follow up period was 12.7 months (range: 6-20). Tendoscopy was performed using posteromedial, posterolateral, and plantar portals. Clinical evaluations included preoperative and postoperative visual analogue scale (VAS), American orthopaedic foot and ankle society (AOFAS) score, and patients' satisfaction. Results: Tendoscopic findings included tenosynovitis in 10 cases, degenerated vinculae in 6 cases, stenosis of the tendon at its entrance into the fibro-osseous tunnel in 5 cases, and degenerative partial tendon tear in 3 cases. Two cases had associated symptomatic os trigonum and 3 cases had posterior ankle impingement syndrome. Preoperative pain decreased from median VAS 6 (range: 4-10) to 2.1 (range: 1-5) at the last follow up and AOFAS score improved from 50.1 (range: 36-63) to 82.1 (range: 61-89) (p<0.05). Nine patients were satisfied or very satisfied with the outcome. Injury of the lateral plantar nerve occurred in one case. Conclusion: FHL tendoscopy using 3 portals is a feasible and useful minimal invasive surgical technique for the management of FHL tenosynovitis.

Purpose: Number of arthroscopic surgery is gradually increasing with development of its equipment and technique. Arthroscopic ankle surgery performed with the traction device has various complications and need more time for preparation. We investigated whether the complication rate increased when surgery was performed without the traction device, and compared the complication rate of arthroscopic surgery with the traction device. Materials and Methods: From January 2009 to June 2012, arthroscopic ankle surgery was performed without the traction device in four hundred eleven cases. There were two hundred sixty-one males and one hundred fifty females. The average age at operation was 35 years (range, 17-56), and the average follow up period was 28 months (range, 12-41). Postoperative symptoms and complications were checked. Results: There were difficulties performing arthroscopic surgery without the traction device in five cases with severe traumatic osteoarthritis. However, after burring and shaving, we had enough space to work on. Superficial peroneal nerve symptom was found in two cases, grooving of talus was found in 11, and saphenous vein injury was found in five. Since preparing for the traction device was unnecessary, we were able to save time with the mean duration of surgery of 50 minutes (range, 30-120). Conclusion: With only manual traction, we could explore the entire ankle joint without damage on cartilage. Yet, skilled arthroscopic technique will be necessary for arthroscopic surgery without the traction device.

To have effective treatment for shoulder arm pain, we searched the cause, symptom, etiology, classification of the pain areas, acupuncture points, and muscles along the meridians, and acquired the following results. Shoulder-pain is mainly divided into the malfunction of viscera and entrails, damage due to the weakness of essence and qi, abnormal status of muscle function, change of joints, disease in the nerve and vessel, and the internal injury due to seven modes of emotions. Pain of shoulder joints are pain in the local area of shoulder joints, referred pain of shoulder, neck, and shoulder-arm, numbnes and swelling of muscle, and muslce weakness. Shoulder-arm pain is classified as four types of pain: shoulder-joint pain, shoulder-back pain, shoulder-chest pain, and shoulder-arm-elbow pain. And shoulder-arm-elbow pain is again divided into the shoulder-blade pain, shoulder-arm pain, shoulder-elbow pain. The related meridians on shoulder pain are the three yin meridians of hand, Kidney Meridian, Conception Meridian, three yang meridians of hand, Bladder Meridian, Governor Meridian Acupuncture points for shoulder pain are in the acupuncture points of the 10 meridians and a-shi points. Thre related meridian muscles on shoulder-pain are the three yin and yang meridians of hand, and their related muscles are the ones that are connected with the front, back, and chest side muscles of shoulder joints, and the ones that are connected with the front and back side muscles of arm.

Background: An intravenous infusion of lidocaine has been used on numerous occasions to produce analgesia in neuropathic pain. In the cases of failed back surgery syndrom, the pain generated as result of abnormal impulse from the dorsal root ganglion and spinal cord, for instance as a result of nerve injury may be particularly sensitive to lidocaine. The aim of the present study was to identify the effects of IV lidocaine on neuropathic pain items of FBSS. Methods: The study was a randomized, prospective, double-blinded, crossover study involving eighteen patients with failed back surgery syndrome. The treatments were: 0.9% normal saline, lidocaine 1 mg/kg in 500 ml normal saline, and lidocaine 5 mg/kg in 500 ml normal saline over 60 minutes. The patients underwent infusions on three different appointments, at least two weeks apart. Thus all patients received all 3 treatments. Pain measurement was taken by visual analogue scale (VAS), and neuropathic pain questionnaire. Results: Both lidocaine (1 mg/kg, 5 mg/kg) and placebo significantly reduced the intense, sharp, hot, dull, cold, sensitivity, itchy, unpleasant, deep and superficial of pain. The amount of change was not significantly different among either of the lidocaine and placebo, or among the lidocaine treatments themselves, for any of the pain responses, except sharp, dull, cold, unpleasant, and deep pain. And VAS was decreased during infusion in all 3 group and there were no difference among groups. Conclusions: This study shows that 1 mg/kg, or 5 mg/kg of IV lidocaine, and palcebo was effective in patients with neuropathic pain attributable to FBSS, but effect of licoaine did not differ from placebo saline.

Purpose: We wanted to evalulate the clinical results of pectoris major tendon transfer for a neglected winged scapula that was caused by paralysis of the serratus anterior due to injury to the long thoracic nerve. Materials and Methods: A patient had neglected winged scapula that followed an arthroscopic operation for multi-directional instability of the shoulder joint, which was caused by traumatic dislocation. The patient was treated with pectoralis major tendon transfer using the modified Eden-Lange procedure. The range of a motion was improved from forward flexion $90^{\circ}$ and external rotation $70^{\circ}$ to $170^{\circ}$ and $150^{\circ}$ respectively. Results and Conclusion: There were no complications or recurrence and the patient's psychological satisfaction was also high. If the shoulder girdle muscles are intact, except for the serratus anterior, then pectoralis tendon transfer is a satisfactory method that can provide normal scapulo-thoracic motion.

Background: Carotid endarterectomy (CEA) with selective shunting is the surgical method currently used to treat patients with carotid artery disease. We evaluated the incidence of major postoperative complications in patients who underwent CEA with selective shunting under transcranial Doppler (TCD) at our institution. Methods: The records of 45 patients who underwent CEA with TCD-based selective shunting under general anesthesia from November 2009 to June 2015 were reviewed. The risk factors for postoperative complications were analyzed using univariate and multivariate analysis. Results: Preoperative atrial fibrillation was observed in three patients. Plaque ulceration was detected in 10 patients (22.2%) by preoperative computed tomography imaging. High-level stenosis was observed in 16 patients (35.5%), and 18 patients had contralateral stenosis. Twenty patients (44.4%) required shunt placement due to reduced TCD flow or a poor temporal window. The 30-day mortality rate was 2.2%. No cases of major stroke were observed in the 30 days after surgery, but four cases of minor stroke were noted. Univariate analysis showed that preoperative atrial fibrillation (odds ratio [OR], 40; p=0.018) and ex-smoker status (OR, 17.5; p=0.021) were statistically significant risk factors for a minor stroke in the 30-day postoperative period. Analogously, multivariate analysis also found that atrial fibrillation (p<0.001) and ex-smoker status (p=0.002) were significant risk factors for a minor stroke in the 30-day postoperative period. No variables were identified as risk factors for 30-day major stroke or death. No wound complications were found, although one (2.2%) of the patients suffered from a hypoglossal nerve injury. Conclusion: TCD-based CEA is a safe and reliable method to treat patients with carotid artery disease. Preoperative atrial fibrillation and ex-smoker status were found to increase the postoperative risk of a small embolism leading to a minor neurologic deficit.

Objective : The purpose of this report is to assess the morbidity and mortality associated with clipping of intracranial unruptured aneurysms. Methods : At the authors' institution between May 1989 and December 1998, a total of 128 unruptured aneurysms in 110 patients were treated with surgical clippings. The medical records and neuroimaging studies of the patients were reviewed retrospectively. Results : The main locations of the aneurysms were : middle cerebral artery 31%, internal carotid-posterior communicating artery 28%, anterior communicating artery 16%, paraclinoid 6.5%, internal carotid-anterior choroidal artery 7%, posterior circulation 7%. Forty three percent of the aneurysms were symptomatic and 57% asymptomatic. The overall outcome of the surgery was : Glasgow outcome scale(GOS) I 86%, GOS II 6%, GOS III 4.3%, GOS IV 0% and GOS V(death) 3.5%. The operative risk is higher for large to giant aneurysms, and for aneurysms in posterior circulations. Patients with non-giant aneurysm in anterior circulation showed no mortality, but morbidity of 8.2%, and in posterior circulation : 25% of mortality and 75% of morbidity. Patients with giant anterior circulation aneurysm have 22% of mortality and 22% of morbidity. For patients with giant posterior circulation aneurysm, mortality and morbidity were 25% and 25%, respectively. The postoperative deaths were related to occlusion of the major parent artery in 3 cases(75%). The postoperative morbidity was related to occlusion of artery(9/13), intraoperative rupture(3/13), and cranial nerve injury(1/13). Conclusion : This report documents 3.5% mortality and 13% of morbidity in the clipping surgery for unruptured intracranial aneurysms, and the relatively low risk of surgical clipping in non-giant and those located in anterior circulation. The natural history, especially risk of bleeding, of the unruptured intracranial aneurysms is still controversial. However, with respect to surgical results, unruptured non-giant aneurysm located in anterior circulation should be operated in patients with low risk.

Although nerve injury is the most common complication of pneumatic tourniquets, it is said to be rare, with few case reports. We describe two cases of paralysis after upper extremity surgery to highlight this risk. Ulnar, median and radial neuropathies were diagnosed after surgery was performed on a man for left hand reconstruction, presumably due to a prolonged total inflation time of 14 hours despite conventional break times. A woman who received surgery for a crushed hand presented with radial neuropathy, the most probable cause being malfunction and automatic inflation of the tourniquet. These cases illustrate the diversity of tourniquet paralysis, with symptomatic progress not necessarily following electromyography results. The considerable discomfort to patients warrants careful use of tourniquets for neuropathy prevention.
