  • Surgical treatment of compressive ulnar neuropathy at the elbow has been performed with a wide variety of techniques. Among these techniques, anterior submuscular transposition of the ulnar nerve has been regarded as the method of choice by many authors. It has many advantages including a low recurrence rate, scar-free vascular bed, and protection from repeated trauma to the nerve. However, anterior submuscular transposition is technically demanding and requires more extensive soft tissue dissection. On the other hand, anterior subfascial transposition is less invasive, requires a relatively shorter operation time than the submuscular technique, and also can be done safely even in patiensts with elbow arthritis. We evaluated the clinical results of anterior submuscular transposition compared with anterior subfascial transposition. Fifteen patients underwent anterior submuscular transposition and ten patients underwent anterior subfascial transposition of the ulnar nerve. The mean follow-up time was 15 months (range 10 to 38 months) in the anterior submuscular transposition group and 7 months (range 6 to 15 months) in the anterior subfascial transposition group. According to the outcome status determination algorithm devised by Mowlavi, 3 patients (20%) showed total relief, 10 patiensts (66.7%) improvement and 2 patients (13.3%) no changes in the anterior submuscular transposition group. In the anterior subfascial transposition group, 2 patients (20%) showed total relief, 7 patients (70%) improvement and 1 patient (10%) displayed no changes. Statistically there was no significant difference of the clinical results between the two surgical techniques. Therefore we would suggest anterior subfascial transposition of the ulnar nerve as a preferred method for treatment of cubital tunnel syndrome.

  • Surgical treatment of cubital tunnel syndrome has been reported according to a wide variety of techniques since the end of the last century. Theses range from simple decompression to various forms of nerve transposition and medial epicondylectomy. However, we could find only few reports which compare the results between different types of operations. The treatment results of medial epicondylectomy and anterior subcutaneous transposition, were analysed retrospectively. From March 1984 to January 1996, a total of 110 patients had operations for cubital tunnel syndrome. Seventy four of them were followed-up for more than one year, and only they were included in this study. Anterior subcutaneous transposition was performed in 26 patients; and medial epicondylectomy in 48 patients. There were 52 males and 22 females, with an average age of 34 years (range, 13 to 75). The average follow-up period was 40 months (range, 12 to 132). Grading system by Gabel and Amadio were used for evaluation of the patients; pain, sensory and motor dysfunction were checked preoperatively and at last follow-up. In 26 patients of anterior subcutaneous transposition, 7 (27%) were graded as excellent, 11 (42%) good, 3 (12%) fair and 5 (19%) poor. In 48 patients of medial epicondylectomy, 16 (34%) were excellent, 27 (56%) good, 3 (6%) fair and 2 (4%) poor. Sixty nine percent were excellent or good in anterior subcutaneous transposition group, while ninty percent in medial epicondylectomy group. This difference was significant statistically (p<0.01 )., From our experiences, we suggest medial epicondylectomy for the treatment of cubital tunnel syndrome, rather than anterior subcutaneous transposition.

  • Purpose: To evaluate the clinical results of anterior subcutaneous ulnar nerve transposition operation and the factors that influence the results for cubital tunnel syndrome. Materials and Methods: Seventeen cases of cubital tunnel syndrome were treated by anterior subcutaneous transposition between March 2001 and December 2003. The mean age was 56 years and mean follow up period was 20.4 months. All patients were reviewed retrospectively. The preoperative evaluation was done by Dellon's classification and the clinical results were evaluated by Messina’s classification. We analyzed the effect of the operation and the relations between the results and the preoperative factors, for example, duration of symptom, age, cause of illness, present of association with diabetes mellitus or preoperative flexion contracture of the elbow were analyzed. Results: The results according to Messina's classification were 4 cases of excellent, 9 cases of good, 3 cases of fair, and 1 case of poor. The preoperative factors like duration of symptom, age, cause of illness and flexion contracture of the elbow didn't show any statistical difference in the result of operation, but the cases which have diabetes mellitus were unsatisfactory with statistical difference (p=0.018). Conclusion: Anterior subcutaneous ulnar nerve transposition is relatively easy and good operative method in cubital tunnel syndrome.

  • In this report, a case of a 70-year-old man with a large ganglion cyst formed after anterior transposition of the left ulnar nerve is presented. Three months after the index surgery, the patient presented with a painless superficial ovoid, soft mass measuring $5{\times}4{\times}2cm$ in size located at the posteromedial aspect of the left elbow, the previously operated site. Magnetic resonance imaging showed a well demarcated cystic mass with a stalk connecting to the elbow joint. Excisional biopsy was performed and pathologic findings showed that the cystic wall had no definite lining cells with myxoid degeneration compatible with findings of ganglion cyst.

  • After dual plating with a locking compression plate for comminuted intraarticular fractures of the distal humerus, the incidence of ulnar nerve injury after surgery has been reported to be up to 38%. This can be reduced by an anterior transposition of the ulnar nerve but some surgeons believe that extensive handling of the nerve with transposition can increase the risk of an ulnar nerve dysfunction. This paper reports ulnar nerve injuries caused by the incomplete insertion of a screw head in dual plating without an anterior ulnar nerve transposition for AO/OTA type C2 distal humerus fractures. When an anatomical locking plate is applied to a distal humeral fracture, locking screws around the ulnar nerve should be inserted fully without protrusion of the screw because an incompletely inserted screw can cause irritation or injury to the ulnar nerve because the screw head in the locking system usually has a slightly sharp edge because screw head has threads. If the change in insertion angle and resulting protruded head of the screw are unavoidable for firm fixation of fracture, the anterior transposition of the ulnar nerve is recommended over a soft tissue shield.

  • This is one case report of the extremely rare congenital cardiac malformation, Double-outlet of left ventricle in corrected transposition of great arteries. 11-year-old boy complained acrocyanosis and exertional dyspnea, the parents noticed cyanosis since birth. Physical examination revealed acrocyanosis, clubbed fingers and toes, G-III pansystolic murmur on 2nd and 3rd ICS, LSB. Right heart catheterization revealed significant $O_2$ jump in ventricular level. Right and left ventriculography showed the both catheters arriving in the same ventricle i.e. anterior chamber, morphological left ventricle was in right and anterior position, simultaneous visualization of aorta and pulmonary artery and aorta locating anterior and right side of pulmonary artery. Echo cardiogram surely disclosed interventricular septum. Conclusively it was clarified that the patient has Double-outlet of left ventricle and corrected transposition of great arteries [S.L.D.]. Operation was performed to correct the anomalies under extracorporeal circulation with intermittent moderate hypothermia. Right-sided ventriculotomy disclosed the following findings. 1. Right-sided ventricle was morphological left ventricle. 2. Left-sided ventricle was morphological right ventricle. 3. Right side atrioventricular valve was bicuspid. 4. Left side atrioventricular valve was tricuspid. 5. Aortic valve was superior, anterior and right side of pulmonary valve. 6. Subpulmonary membranous stenosis. 7. Non-committed ventricular septal defect. We made a tunnel between VSD and aorta with Teflon patch so that arterial blood comes through VSD and the tunnel into aorta. After correction the patient needed assisted circulation for 135 min. to have adequate blood pressure. Postoperatively by any means, adequate blood pressure could not be maintained and expired in the evening of operation day.

  • From August 1990 through December 1991, 14 patients[all males] underwent int-rathoracic muscle transposition of extrathoracic skeletal muscles to treat empyemas, 6 patients had tuberculous empyemas, 4 had chronic empyemas of unknown etiology, 3 had pos-tpneumonectomy empyemas, and 1 had postlobectomy empyema. 9 patients had associated bronchopleural fistulas, Their ages ranged from 22 to 67 years, with mean age of 45.1$\pm$17. 6[$\pm$S.D] years. The serratus anterior was transposed in 13 patients, the latissimus dorsi in 12. In 11 patients, both the serratus anterior and the latissimus dorsi were transposed. The omental flap also transposed in 3 patients. To reduce the dead space in the thoracic cavity, thr-oacoplasty was also carried out in 10 patients. The number of the partially resected ribs was 3.0$\pm$0.8[$\pm$S.D.]. All operations were single stage procedures, and all wounds were closed primarily, with no permanent tubes or chest wall openings. There was no hospital mortality, and so no subsequent operation has been required. Follow-up of the patients ranged from 5 to 16 months with a mean of 9.2$\pm$3.1[$\pm$S.D] months, All the patints had no further signs or symptoms of the original infection after discharge. We conclude that intrathoracic transposition of extrathoracic skeletal muscle is an excellent method of treatment for persistent, life-threatening intrathoracic infections.

  • Esophagopleural fistula is a rare complication that should be suspected in all patients with recurrent empyema following pneumonectomy and in whom a bronchopleural fistula can be excluded. In late postpneumonectomy esophagopleural fistula, diagnosis is difficult due to its rarity and no specific symptom and sign, but we have experienced a man who had suffered dysphagia and odynophagia. In surgical treatment of late postpneumonectomy esophageal fistula, closure of empyema space is of prime importance. We have adopted a type of latissimus dorsi muscle and serratus anterior muscle flap transposition We present here this technique and result obtained in patient with late postpneumonectomy esophagopleural fistula.

  • Cubital tunnel syndrome refers to compression neuropathy caused by pressure on the ulnar nerve pathway around the elbow. A 63-year-old male patient visited the clinic complaining of decreased sensation and weakness in his left ring finger and little finger, stating that the symptoms first began 6 months prior. He had undergone surgery to remove a ganglion cyst from his left elbow joint about 5 years prior in Mongolia. Magnetic resonance imaging revealed a cystic mass located at the previous surgical site, which was compressing the ulnar nerve within the cubital tunnel. Ulnar nerve decompression and anterior transposition were performed, and the cystic mass was excised. Upon pathological examination, the mass was diagnosed as a ganglion cyst. The patient's symptoms including sensory dysfunction and weakness improved over the 1-year follow-up period. This report describes a rare case of ganglion cyst recurrence compressing the ulnar nerve in the cubital tunnel after previous ganglion cyst excision.
