The purpose of this clinical study is to assess whether calcium hydroxide as an intracanal medication affects post-treatment pain in teeth especially odontogenic pain which comes from inflammation of the pulp and periradicular tissues when compared with no intracanal medication. From 213 patients who has been treated 237 root canals due to significant pain (moderate-to-severe) we recorded their age, sex, treated tooth, degree of pain, pre-operative states of the tooth. We classified patients into 2 test group; Group 1 (not gain intracanal $Ca(OH)_2$), Group 2 (gain intracanal $Ca(OH)_2$). Through the survey from the patients, we let them write down the occurrence and degree of post-treatment pain in 4hours, 2days, 7days after treatment as none, mild, moderate or severe. The followings were evaluated ; the overall incidence of flare-ups, the overall incidence of post-treatment pain in each group at each time period , the incidence of post-treatment pain in each group at each time period as related to pre-operative states of the teeth These were compared statistically with Chi-square analysis (p < 0.05). Under the condition of this investigation, no difference was observed in the incidence of post-treat-ment pain between the two groups. Therefore, $Ca(OH)_2$ as intracanal medication had no effect on preventing or decreasing the post-treatment pain.

Remarkable effect of pain relief and prevention of the postoperative Complications after thoracotomy has been achieved by continuous intravenous analgesia. This study was carried out with thirty patients who underwent posterolateral thoraco tony. The patients were divided into three groups: Group I(n= 10), the patients with intermittent intramuscular analgesia(piroxicam 20 mg), Group II(n=10), the patients with continuous epidural analgesia(0.5% bupivacaine 30m1 + normal saline 30 ml + morphine 10 mg), and Group III(n= 10) the patients with controlled intravenous infusion of analgesics(fentanyl 2500 mfg +normal saline 10 ml). The results w re as follows; 1) There were no significant changes of vital signs, between groups. 2) Tidal volume and FVC were significantly improved in the group II and III compared with the group I during the first postoperative day. 3) A significant reduction of immediate post-thoracotomy pain was achieved in the group II and III compared with the group I. 4) The limitation of motion in the operative side was less in the group II and III compared with the group I. 5) A signi(icant reduction of the postoperative analgegics consumption was noticed in group II and III. 6) Significant complications were not occured during follow-up period in all groups.

전방십자인대 재건술시 이식건의 과간 절흔에 대한 충돌을 예방하기 위하여 어느 절도의 절흔 성형을 시행 할 것인가에 대하여는 아직까지 논란이 있으며 수술시 절흔의 형태, 골극 형성 유무, 이식건의 크기 경골 터널의 위치를 고려하여 시행하여야 한다. 절흔 후방의 골 제거가 과도하게 시행 될 경우에는 대퇴골 부착부가 외측으로 전위되어 슬관절의 생역학적 변화를 가져올 수 있고, 주변 관절 연골의 조기 퇴행성 변화를 초래할 수 있으므로 세심한 주의를 기울여야 하며 절흔 성형은 가능한 한 최소화 하는 것이 출혈, 동통 및 부종 등의 술후 합병증을 줄일 수 있다.

Purpose : To evaluate the results and usefulness of meniscal repair using meniscal arrows with ACL reconstruction. Material and Methods : Among cases of the simultaneous meniscal arrow fixation and ACL recontruction performed between May, 1997 and September, 2000, 17 cases could be evaluated. The average follow-up were 18.5 months. Twelve cases were medial meniscus, 5 cases, lateral meniscus. All cases were longitudinal tear. Meniscal tear were seen at red-red zone in 13 cases, red-white zone in 5 cases. The results were analyzed by pain, joint line tenderness, locking, McMurray test, the Marshall knee scoring scale and complications. Results : Postoperatively two patients had mild joint line tenderness without pain on joint motion or weight bearing. No patient had locking or positive McMurray test. At last follow-up, 15 cases $(88\%)$ were 'excellent' or 'good' according to the Marshall knee score scale. There were two complications which are soft tissue irritation sign on active knee motion and a femoral chondral injury due to protruded T-shaped head of meniscus arrow. Conclusion : Meniscus arrow can be one of the options in repairing the associated meniscus tear, especially the posterior horn of medial meniscus, during ACL reconstruction. However, surgeons using meniscus arrow should be aware of its potential complications such as pain due to soft tissue irritation and chondral damage of the femoral condyle.

Purpose : To describe clinical results and improvement of range of motion and pain after arthroscopic treatment for the athletic elbow lesion. Materials and Methods : We reviewed 13 cases of functional restriction of the elbow motion, who all patients were treated by conservative treatment during than 6 months but failed. We performed arthroscopic osteophytectomy, capsular release, spur excision. The interval from injury to operation was average of 13 months (range, eight to sixteen months). We used the Broberg and Morrey functional rating score system in evaluating result. The follow-up period averaged 6 months. Results : Arthroscopic finding that moderative to severe synovitis in all cases, intraarticular loose body in 9 cases, olecranon bony spur in 2 cases, was observed. All cases were successfully improved in range of motion and pain without in any further operation. Preoperative average score was 65 and postoperative average score was 89.4 in Broberg and Morrey functional rating score. Conclusions : Arthroscopic treatment appear to be satisfactory management modality due to diagnose the casative factor and reduce the injury around the elbow joint in painful elbow lesion. Elbow arthroscopy appears to be a safe and effective treatment for athletes, allowing easy return to participation in sports.

A 34-year-old man with ACL total rupture due to slip down injury, had received ACL reconstruction using autogenous hamstrings tendon with cross-pin femoral fixation. Postoperative course was as usual. But postoperative 3 months later, he complained posterolateral knee pain, recurrent effusion and mild instability. He was managed repeatitive aspiration and nonsteroid antiinflammatory drugs but was failed to relieve symptoms & signs. In CT scans, perforation of posteromedial femoral cortex of lateral femoral condyle was found. In second look arthroscopy, two pieces of broken femoral cross pin were found in between tibiofemoral Joint which was badly injured cartilage. We considered malposition of pins was the main cause of failure. We propose that femoral tunnel must be made more acute angle and femoral cross-pin guide must be positioned more external rotation 10-20 degree than transepicondylar axis made confirm the cross-pin tunnel position in order to avoid posterior cortex perforation and early failure.
