The ultrasound is also helpful to make the diagnosis of a variety of soft tissue tumors bacause of its safety, low cost, non-invasiveness and usefulness. We analysed ultrasonographic findings of 43 cases of soft tissue tumors which were histopathologically confirmed by biopsy and obtained the following results. The ultrasonography could effectively image not only the presence, size and location of the lesion, but also the relationship between the lesion and the adjacent structures. And this method could easily identify the consistency of the lesion, solid or cystic nature, be used to guide the percutaneous biopsy and aspiration without exposure to radiation, and afford the differentiation of malignant lesion from benign one. It could also define the eritities of soft tissue tumors by the nature of internal echo, margin of the lesion, internal echo homogeniety, post-acoustic enhancement, and so on.

The function of the meniscus and subsequently the importance of meniscus preservation are well known. Thirty-two patients who underwent arthroscopic meniscus repair between 1993 and 1995 were studied retrospectively. Twenty menisci were repaired using modified Henning inside-out technique and the remaining twelve meaisci, outside-in technique. The average delay in surgery was two hundred days. Follow-up was done from 1 year to 3 years (average 22.4 months). The medial meniscus was repaired in 22 cases and the lateral meniscus including two saucerized discoid meniscus in 10 cases. Fourteen patients had anterior cruciate ligament (ACL) tear and other associated knee injuries were lateral condyle fra'cture of femur in one case and lateral condyle &acture of tibia in one case. Assessment of the result was based on the evaluation form of the International Knee Documentation CommitteegKDC). Twenty-seven patients (84.3%) were normal to nearly normal. Abnormal and severely abnormal results were mainly affected by the result of treatment of ACL tear.

To determine the usefulness of MR axial images for diagnosis ACL tears, we reviewed MRIs of 67 patients with ACL tear confirmed by arthroscopic examination, retrospectively. There were 53 acute and 14 chronic tears. The axial MR images had a 97% sensitivity(acute: 96%, chronic: 100%). Findings of acute ACL tears on sequential axial imaging could be categorized as 1) diffuse swelling with abnormal substance signal in 14 cases(27.5%), 2) focal bulging or irregularity of medial border in 11 cases(21.6%) or 3) combination of the two in 26 cases(50.9%). Findings of chronic ACL tears also could be categorized as abnormally irregular thin fibers in 6 cases(42.9%) or nonvisualization(empty lateral wall) in 8 cases(57.1%). We concluded that MR axial images could provide additional useful information in the diagnosis of ACL tear.

Treatment for the femoral shaft fractures in adolescents is somewhat controversial. These fractures have been treated nonoperatively, but adolescents tolerate prolonged immobilization less well than younger children and conservative treatment in this age group may result in more complicationssuch as malunion, shortening and angular deformities more often than those in the younger age group. Recently there has been a tendency to choose the operative method rather than traditional traction and casting technique for femoral shaft fractures in elderly children and adolescent The purpose of this study is to find better treatment for the femoral shaft fractures in adolescents. Fifty six femoral shaft fractures in 56 patients aged 10 to 14 years old were treated with traction followed by casting, open reduction and internal fixation with plate, closed intramedullary nailing, or external fixation using A-0 external fixator, and evaluated respectively for at least 1 year. External fixation may be benefit to patients with concomittant injuries and result in psychological settle down, early mobilization out of bed, short hospital stay, save of cost,and early return to daily living activities without any disadvantages such as malunion, leg length discrepancy or awareness of growing arrest in spite of negligible pin tract infection. Result of this study suggests that external fixation for the femoral shaft fractures may be an one of the attractive treatment option in adolescents.

Although there are various methods of operative treatment for hony mallet finger, the operative technique is not so easy and complications such as joint stiffness, sott tissue prohlems, infection, change of nail shape and arthrosis are common. The authors performed operations for 26 cases of hony mallet fingers, fixing the hony frapment by Kirschner wire, pull-out wire suture and miniscrew respectively, from Jan. l988 to Jun. l996. The results were as follows. l. According to Niechajev's classification. there were 3 cases of type B, 7 cases of type C, l4 cases of type D, and 2 cases of type E. And 11 cases were accompanied hy crushing injury. 2. Involved fingers were third finger in 11cases, fit'th finger in 7 cases, fourth finger in 5 cases, second finger in 2 cases. and thumb in I case. 3. The hony mallet finger was caused hy occupational injury in l6 cases, direct blow in 7 cases and sports injury in 3 cases. 4. The fractured fragment was fixed hy Kirschner wire in 9 cases, by pull-out suture in 9 cases and by miniscrew in 8 cases. 5. The results were evaluated hy Kanies scale. Sixteen cases had satisfactory results. Seven cases (87.5%) were satisfactory in miniscrew fixations. 5 cascs (55.6%) in pull-out wire suture methocls and 2 cases (22.2%) in Kirschner wire tixations. 6. The complications were joint incongruity in 4 cases, dorsal prominece in 6 cases, painful limitation of motion in 2 cases which were treated by arthrodesis, pin site infection in 2 cases and hreakage of wire suture in 1 case. 7. The miniscrew fixation offered relatively firm fixation, low complication rate, and good results. so it can be considered as one of the good methods of treatment for hony mallet finger.

Horizontal tear of the meniscus occurs most commonly in older patients. The tear begins initially with a simple horizontal cleavage which divides the meniscus into superior and inferior leaves resembling a fish mouth and which may become a flap or more complex tear with time if subjected to repeated injury. Thirty-four patients(36knees/40menisci) with horizontal tear of the meniscus, treated with arthroscopic partial meniscectomy except in 3 extensive tears at Ulsan University Hospital from Jan. 1993 to Jun. 1996, were analyzed to investigate the factors that may be associated with this type of meniscal tear, and the results were as follows; 1. The tears commonly occurred in labor workers(61.7%) and without obvious trauma history(67.6%), and the average age at the time of surgery was 44 years. 2. The most common site of the tear was posterior horn of the medial meniscus (62.5%). 3. The 40 horizontal tears consisted of 12 horizontaVcleavage(30%), 3 horizontaVflap(7.5%), and 25 horizontaUdegenerative complex tears(62.5%). 4. Degenerative changes were frequently noted in both arthroscopy(69.5%) and roentgenography (72.2%).
