Myelopathy or dysfunction of the spinal cord, can be caused by degenerative processes of the cervical vertebrae. Cervical spondylotic myelopathy can be divided into five distinct syndromes on the basis of clinical presentation by Ferguson. Absolute indication for surgery is the progression of neurologic deficit. Decompression may be achieved using an anterior, posterior, or a combined approach, but each patient has unique clinical conditions that require individualized treatment. The purpose of the study was to evaluate the operative results by the clinical manifestation. In evaluating the results, the evaluation system established by the Japanese Orthopedic Association was employed. The average preoperative score in the 14 patient was 8.7 points and the average postoperative score was 12.7 points. The better results have been obtained for those who were managed with decompression within 1 year after onset of symptoms and those who had lateral type. In conclusion, the prognosis for the recovery of the spinal cord function is related with the onset of clinical symptoms and degree of neurological deterioration, so early detection and operative decompression for cervical spondylotic myelopathy may be the best method for the prevention of those unwanted and potentially devastating neurological deteriorations.

Isometric positioning of the ACL graft is an important consideration in successful reconstruction of the ACL-deficient knee. The purpose of this study is to get a certain guideline in the endoscopic one-tunnel technique of anterior cruciate ligament reconstruction by measuring the skin angle and determine the degree of minimum flexion of the knee joint during femoral tunneling and interference screw fixations. To get the guide lines, first we get the tibial tunnel angle parallel to the Blumensaat's line from fully extended lateral knee joint radiography. Secondly measure the differences between angles of the femur-tibia shaft and anterior thigh-leg skin. Then measure the minimum femur-tibia flexion angle does not perforated the posterior cortex of the distal femur during femoral tunneling. Intraoperative measuring the angle between interference screw guide pin and tibial tunnel to get the parallelism of the femoral tunnel and interference screw. The results were as follows; The average femur-tibia shaft angle with 30degrees anterior thigh-leg skin angle was 30.2+/-1.75degrees, with 45degrees was 45.2+/-1.23degrees, with 60degrees was 61.9+/-4.23degrees, with 75degrees was 78.6+/-2.62degrees, with 90degrees was 97.8+/-3.96degrees. Predetermined sagittal tibial tunnel vector on the 0degrees extension knee joint lateral radiographs were applied to the several knee joint dynamograms. The mean minimum flexion angle of the femur-tibia shaft that doesn't perforate the posterior cortex of the femur was 45+/-1.58degrees (male), 44.5+/-4.97degrees (female). The average angle between interference screw guide pin and tibial tunnel was 23.0+/-2.23degrees. The findings of the present study suggest that anterior thigh-leg skin angle can be used instead of the true femur-tibia shaft angle. Less knee flexion angle makes good arthroscopic view during the tibio-femoral tunneling and interference screw fixation.

SUMMARY: Benign fibrous histiocytoma of the knee is a very rare entity. We report on one case of benign fibrous histiocytoma that involved the patellar fat pad, an areas of involvement not previously reported. Diagnostic arthroscopy was performed to show retrobulging of infrapatellar fat pad without specific synovial changes. The lesion was completely resected. At short-term follow-up, all symptoms were resolved. Arthroscopy can be used as an diagnostic tool for identification of intraarticular lesions of the knee, but appears not to be a good tool for clean removal of mass within patellar fat pad.

The endoscopic single-incision technique using interference fit screws to secure patellar tendon-bone plugs in the femoral and tibial tunnels has been very popular method for ACL reconstruction. However, several potential complications has been reported such as violation of the posterior wall of the femoal tunnel, laceration of graft during femoral screw insertion, protrusion of the tibial bone block distally due to a lengthy graft and more frequently divergence of the femoral interference screw. We performed 56 consecutive endoscopic ACL reconstruction. In Groi.p I, femoral tunnel drilling were performed at 70-80 degrees of knee flexion. In Group 11, they were done at $5 degrees of knee flexion. Postoperative radiographic analysis of bone-interference screw divergence angle shows 5.9 degrees in AP view, 6.21 degrees in Lateral view in Group I and 3.14 degrees, 3.35 degre.s in Group II respectevely. In conclusion, Bone-interference screw divergence can be decreased with less knee flexion about 45 degree during preparing femoral tunnel.

A major cause of less than ideal results following intraarticular anterior cruciate ligament (ACL) reconstruction has been imprecise nonanatomic tunnel position for graft placement either in the femur, the tibia, or both. Lack of defined constant reference landmarks for reproducible tunnel placement has contributed to this problem on both sides of the joint. The purpose of this study was to define constant anatomic intraarticular and extraarticular landmarks that can be used as definitive reference points to reproducibly create a tibial tunnel for ACL reconstruction that (1) results in an impingement-free graft in full extension; (2) positions the tibial tunnel such that the sagittal tunnel-plateau angle is parallel with the sagittal intercondylar roof-plateau angle in full extension to minimize shear seen by the graft at the tibial tunnel inlet. Preoperative full extension and 90degrees flexion lateral radiographs were obtained. Preoperative measurements of the tibial tunnel-tibial shaft angle and distance from inferior pole of patella to entry point of tibial tunnel were useful tool for impingement free, Blumensaats line paralleling ACL reconstruction with autogenous bone patella tendon bone graft. The average tibial tunnel-tibial shaft angle was 34+/-4.59degrees (male), 33.5+/-3.37degrees (female). The mean distance between patella inferior pole and tibial tunnel entry point was 6.62+/-0.61cm (male), 6.21+/-0.89cm (female). This study sought to define constant anatomic landmarks extraarticularly as well as intraarticularly that can be used to reliably create an ideal tibial tunnel for ACL reconstruction.

We describe a case of 43-year-old man who had a pseudoaneurysm of the medial superior genicular artery after arthroscopic partial meniscectomy with standard anterolateral and anteromedial portals. Pseudoaneurysm of the medial superior genicular artery has been reported at the previous superomedial portal site after arthroscopy. Described herein is a unique case that involved the medial superior genicular artery at the previous anteromedial portal site after arthroscopy. The pseudoaneurysm was successfully treated with transcatheter embolization.

We report a case of tension pneumothorax after an endoscopic sphincterotomy. A 78-yr-old woman presented with progressing dyspnea. She had undergone an endoscopic retrograde cholangiopancreatogram three days before due to acute cholecystitis. She underwent endoscopic sphincterotomy for stone extraction, but the procedure failed. On arrival to our hospital, she complained about severe dyspnea and she had subcutaneous emphysema. A computed tomogram scan revealed severe subcutaneous emphysema, right-side tension pneumothorax, and pneumoretroperitoneum. Contrast media injected through a transnasal biliary drainage catheter spilled from the second portion of the duodenum. A second abdominal computed tomogram showed multiple air densities in the retroperitoneum and peritoneal cavity, which were consistent with panperitonitis. We recommended an emergent laparotomic exploration, but the patient's guardians refused. She died eventually due to septic shock. Endoscopic retrograde cholangiopancreatogram is a popular procedure for biliary and pancreatic diseases, but it can cause severe complications such as intestinal perforation. Besides perforations, air can spread through the abdominal cavity, retroperitoneum, mediastinum, and the neck soft tissue, eventually causing pneumothorax. Early recognition and appropriate management is crucial to an optimal output of gastrointestinal perforation and pneumothorax.

Bleeding from anastomotic site in operation for aorta has been troublesome, because it has influence on postoperative morbidity and mortality. Therefore, hemostasis is very important. We describe a simple and effective method for achieving hemostasis of the anastomotic site in aortic surgery. By wrapping around anastomotic site with remnant artificial vascular graft, we have acquired good results.

BACKGROUND: Initial symptoms for esophageal perforation have not been clarified, but when there is no early diagnosis and proper treatment to follow immediately after the diagnosis, it is fatal for the patients. Therefore, this study attempted to discover the factors that influence the prognosis of esophageal perforation to contribute to the improvement of the treatment result. MATERIAL AND METHOD: The subjects of this study are 32 patients who came to the hospital with esophageal perforation from October, 1984 to June, 2000. This study examined the items for clinical observation such as patients' sex, age, cause of the perforation, perforation site, the time spent until the beginning of the treatment, symptoms caused by the perforation and its complication, and treatment methods. This study tried to find out the relationship between the survival of patients and each item. RESULT: There were 24 male and 8 female patients and their mean age was 49.7 +/- 16.4. For the causes of perforation, there were 14 cases(43%) of iatrogenic perforation, which ranked first, caused by the medical instrument operation and surgical damage. As for the perforation sites, thoracic esophagus was the most common site(26 cases of 81.2%) and chest pain was the most frequent symptom. The complication caused by esophageal perforation showed the highest cases in the order of mediastinitis, empyema, sepsis and peritonitis. After the treatment, there were 23 cases of survival and 9 cases of mortality. The total mortality rate was 28.1% and the main causes of mortality were sepsis and acute respiratory distress syndrome(ARDS). As for the treatment, 8 cases(25.0%) treated the perforation successfully using conservative treatment only. As for the surgical treatment, there were 5 cases(15.6%) of cervical drainage, 7 cases (21.8%) of primary repair and 12 cases(37.5%) of esophageal reconstruction after performing an exclusion-diversion. There were 18 cases(56.2%) of complete treatment of esophageal perforation at its initial treatment and in 14 cases(43.8%) of treatment failure at its initial treatment, patients were completely cured in the next treatment stage or died during the treatment. The cases of perforation in thoracic esophagus, complication into severe mediastinitis or sepsis and the cases of failure at initial treatment showed a statistically significant mortality rate (p<0.05). CONCLUSION: Based on the above results, it is thought that a proper choice for initial treatment choice depending on the perforation site and the prevention of serious complication such as mediastinitis or sepsis can shorten the treatment period for the patients with esophageal perforation and improve the convalescence.
