Purpose: To report the surgical skills needed, and the clinical results of, minimally invasive hip surgery with dynamic hip screws and the comparison with the classical technique in stable pertrochanteric fractures of the femur. Materials and Methods: Thirty-two patients with pertrochanteric fractures of the femur who were treated with dynamic compression hip screws between April 1999 and March 2004, and were evaluated retrospectively, and were followed up for more than 12 months. 16 cases were treated with a classical dynamic hip screw technique and 16 cases with a minimally invasive technique in random order. The mean age was 73.2 years, and there were 11 males and 21 females. The operative times, total hemovac bleeding loss, functional scores, and average hemoglobin decrease ratios were evaluated. The clinical assessments were performed with the Harris Hip Score (HSS) and bony union was evaluated with serial follow-up plain radiographs. Results: The average operative time was 63.9 minutes with the classical technique and 42.5 minutes with the minimally invasive technique. The total average hemovac blood loss was 640 cc with the classical technique and 143 cc with the minimally invasive technique. Clinically, the HHS was an average of 85.9 and 89.2 in groups 1 and 2, respectively, by the last follow-up and there were no statistically significant differences between the two groups (P <0.05) The hemoglobin decrease ratio was the same in both groups and there was no nonunion. Conclusion: Minimally invasive dynamic hip screw insertion was useful in stable pertrochanteric fractures, because it decreased blood loss and operative times; and there were no changes in fracture healing and functional outcomes.

The significance of the posterior cruciate ligament (PCL) in the stability of the knee and the necessity for surgical repair of its tears are still controversial. The purpose of this study is to present the short term results of surgical repair and Kennedy LAD augmentation for 15 cases with PCL injury. In 14 patients (15 knees), the torn PCL was repaired with pullout suture technique and Kennedy LAD augmentation was done from june 1993 to june 1994. The follow-up period ranged from 12 months to 25 months (average, 18months). The main causes of injuries were traffic accidents in 12. Thirteen of the patients were men and one was a woman, ranging in age from 17 to 52 years(average, 35 years). 10 knees were acute injury and repaired at average 9 days after injury. There were 11 cases that had combined injuries(4 ACL injuries, 4 meniscus injuries, 3 MCL injuries etc). In eight knees, the tear was in mid substance area and in five it was near femoral attach site and in two it was near tibial attach site. Postoperative results were evaluated by roentgenographic evaluation of posterior sagging and Lysholm knee score. 11 knee were stable but 4 knees were unstable posteriorly during postoperative follow-up period. 3 chronic injuried knees were included in 4 posteriorly unstable knees. There are 7 combined knee injuries in 11 stable knees and no combined injuries in unstable knees and average Lysholm knee score was 89.7 in stable knees and 90 in unstable knees and there was no significant difference between two groups. On the based of this study, surgical repair with pollout suture technique and augmentation with Kennedy LAD in acute PCL injury is a one of the good method for preventing posterior sagging but more longer follow-up period and more cases must be needed to accept this method.

Peripartum cardiomyopathy is defined as a syndrome of cardiac failure occurring in tbe latter part of pregnancy or in the puerperium, without obvious cause and without prior evidence of heart disease. Despite its infrequency, this clinical problem may have devastating consequences upon maternal and fetal outcome. It is important to recognize the association of cardiac failure and pregnancy as a separate syndrome so that, once identified, peripartum cardiomyopathy can be treated promptly and aggressively. We experienced two cases of peripartum cardiomyopathy, and report these cases with a brief review of the literatures.

Pigmented villonodular synovitis and synovial chondromatosis are known as a poup of interrelated tumorous disorders that involve the lining of the joints, hursa and tendon sheath. Pigmented villonodular synovitis consists of proliferatin synovia1 tissue containing histiocytes, librohlasts, multinucleated giant cells, and capillaries that can destroy dense fihrous tissue, form soft tissue masses, and invade bone. Synovial chondromatosis consists of hyaline cartilage nodules within the synovium and synovial joint cavities, develop multiple loose fragments of cartilage within the joint. They may represent a reactive inflammatory process or henign neoplasm and usually occur in latge synovial joints, including the knee, hip and ankle. There are some reports stating that pigmented villonodular synovitis has coexisted with synovial chondromatosis. but none have reported that they occurred simultaneously in a large single joint. This is a report on a diagnosed and arthroscopicully treated pigmented villonodular synovitis and synovial chondromatosis that occurred simultaneously in the same ankle joint.

Teratomas of the fallopian tube are extremely rare, and only about 50 cases have reported in the world literature. Most cases of mature cystic tubal teratoma are asymptomatic and are discovered as an incidental finding on physical or radiologic examination, or at the time of laparatomy. We report a case of mature cystic teratoma of the right fallopian tube which was discovered during pelvic ultrasonogram for antenatal care in a 28 year old woman. Right salpingectomy was performed during cesarean section for cephalo-pelvic distortion at IUP 39 weeks. Gross examination of the right fallopian tube reveals a distended fallopian tube, measuring 8cm in length and 2cm in diameter. On section, it is filled with several small pedunculated nodules and cysts containing sebaceous materials. Microscopically the tumor was seen in continuity with the lining epithelium of mucosal folds. The majority of the tumor was composed of well differentiated mature elements of three germ layers with skin and skin appendages, mature brain tissue, bone, breast tissue, intestinal mucosa and bronchial epithelium.

Root conditioning has been introduced to dissolve the smear layer, and to aid in detoxification following root planing. It produces surface demineralization, resulting to exposure of dentin collagen fibrils and opening of dentinal tubules. The purpose of the present study was to examine the possibility of obtaining root conditioning effect by using ethylenediamine tetraacetic acid(EDTA) solution instead of low pH etchants such as citric acid and tetracycline hydrochloride(Tc-HCl). Total 48 root specimens(4x5x2mm) were prepared from the mesial and distal root of 24 periodontitisaffected human mandibular molars after scaling and root planing. The specimens were treated with EDTA(17%, neutral pH, Pulpdent?, Pulpdent Co., USA) for 1 min., 2 min., and 3 min., and tetracycline hydrochloride(100mg/ml) for 5 min. using the rubbing technique and the placement technique without rubbing. The dentinal tubules of the specimens were examined under a scanning electron microscopy(JEOL, JSM- 840A, Japan). On the microphotographs taken at x3,000 magnification, the number of identifiable dentinal tubules, opened dentinal tubules, and fully opened dentinal tubules(over 0.9micrometer in diameter) per the unit area(1,067?m2) were counted. And the rate of opened dentinal tubule and the rate of fully opened dentinal tubule were calculated. The difference of those rates among all groups was statistically analyzed by ANOVA and Dunkan test. The results were as follows; 1. In the specimens applied with EDTA, the rate of opened dentinal tubule was not significantly different between each group regardless of application technique and application time(p>0.1). 2. In the specimens applied with EDTA, the rate of fully opened dentinal tubule had tendency to be increased in proportion to application time regardless of application technique. 3. In the specimens applied with EDTA within 2 min., the rate of fully opened dentinal tubule failed to show significant difference between the two techniques(p>0.1). But, in the specimens applied for 3 min., the rate of fully opened dentinal tubule was significantly higher in the specimens applied by the rubbing technique than those by the placement technique(p<0.001). 4. In the specimens applied with Tc-HCl for 5 min., both the rate of opened dentinal tubule(p<0.01) and the rate of fully opened dentinal tubule (p<0.001) were induced significantly higher by the rubbing technique than the placement technique. 5. The rate of fully opened dentinal tubule was significantly higher in both the specimens rubbed for 3 min. with EDTA and the specimens rubbed for 5 min. with Tc-HCl than other groups(p<0.001). But there was no significant difference between the two(p>0.1). The results demonstrate that 17% EDTA solution can replace low pH etchants for root conditioning, and the rubbing technique for at least 3 min. is recommendable.
