The anterior horn of the medial meniscus is the site of most variations, but anomalies of the medial meniscus are extremely rare. From July 1990 through December 1994, the authors performed arthroscopy on 1068 symptomatic knee joints and incidentally found anomalous insertion of the anterior horn of the medial meniscus into the anterior cruciate ligament in eleven knees. They had another lesion(7 discoid lateral meniscus with or without tear, medial collateral ligament tear, Posterior cruciate ligament avulsion fracture). All but one discoid lateral menisci were reshaped, one had to be treated by total lateral meniscectomy, discoid medial meniscus also by reshaping, torn medial meniscus by partial meniscectomy, torn medial collateral ligament by repair and avulsion fracture of posterior cruciate ligament by arthroscopic pinmonths(average, 21.7 months) after surgery. The results were satisfactory except for 2 patients. One damaged his knee in a traffic accident and the other was treated by total meniscectomy of discoid lateral meniscus. It was concluded that this anomaly was not related to the patient's symptoms and mainly associated with discoid lateral meniscus.

Stress fractures have been well documented in the lower extremity. Stress fractures of the upper extremities are uncommon. We report a case of an ulna stress fracture in a 32 year old female non-professional golfer.

To evaluate the intra-articular pathology of popliteal cysts of knee, we performed arthroscopy on patients with popliteal cysts between February 1992 and February 1995. Thirty-one patients (32 cases) have been treated by excision of cyst after arthroscopy. Mean duration of follow-up was 15 months (13-19 months). Location of cysts was in the right knee in 17 cases, in the left knee in 13 cases, and bilateral in one case. Pain or swelling was present in 12 (38%), giving-way was reported by 4 cases. Three cases revealed quadryceps atrophy. The McMurray test was postive in 6 cases. After arthroscopy, the cysts were excised. Ninteen cases (59%) had associated intra-articular lesions: seven medial meniscal tears, two lateral meniscal tears, seven had chondral damages, one had medial plica syndrome, and one had rheumatoid arthritis, Communication between the cyst and the knee was present in 7 cases (22%), all of whom were over 40 years of age. Thirteen cases was younger than 30 years of age, and 11 cases of these cases had no intra-articular pathology. Two other cases had lateral meniscal tears and medial plica syndrome, respectively. We recommend arthroscopy in middle and older aged patients with popliteal cysts for evaluating and treating intra-articular lesions.

After reconstruction of anterior cruciate ligament, increased idameter of femoral or tibia1 bone tunnel has been obsened on plain radiogram. The etiology of radiographic tunnel enlargement is not well understood and the significance of this tunnel enlargement is unknown. This retrospective study reviewed tibial tunnel diameter in 34 cases of anterior cruciate ligament reconstructions. And we evaluated the correlation between the tibial tunnel enlargement and the position of screw fixation, instability, choice of graft, and clinical results at 1 year postoperatively. AII operation was per formed using a single incision technique. After 3 or 4 months and one year after operation, the diameter of tibial tunnel was measured with digital caliper on the plain radiogram. Tibial tunnel sclerotic margins were measured in the level Of medial tibial plateau on the lateral view of knee. Average tunnel enlargement of 3 allografts was 1.62mm and that of 15 autografts was 2.03mm. No significant difference was seen in KT-10000 arthrometer measurements between enlarged group (amount of enlage-ent >+1 S.D) and not-enlarged group (less than +1 S.D). No coelation was present between the increased tunnel diameter and Lysholm score. Cases with 10mm or more vertical distance between the most proximal point of tihial interference screw and the level of m4eial tibial plateau had average 1.15mm tibial tunnel enlargement and cases with less than 10mm vertical distance ha & I average 2.52mm tibial tunne] enlargement;the difference was not significant (P>0.05). The tibial tunnel enlargement was not correlated with position of screw, clinical results, stability of knee. The tibial tunnel enlargement was not caused hy only mechanical factor such as motion of intra-tunnel portion of graft-tendon.

The original technique for endoscopic anterior cruciate ligament reconstruction has several potential complications because of constraints imposed by working through the tibial tunnel: improper femoral tunnel placement, violation of the femoral tunnel posterior wall, femoral interferenc screw divergence, graft laceration during screw insertion, and distal tibial bone block prr>trusion. We performed 25 endoscopic anterior cruciate ligament reconstructions with bone-tendon-bone graft using a mo3ified technique that minimizes each of these problems, through the use of a anteromedial portal more centrally and distally placed than the original that portal. Postoperative radiographic review showed femoral screw divergence in 20% of cases (2 in the anteroposterior plane, 2 in the lateral plane and 1 in both planes), but the average angles (AP: 0.52+- 1.85, Lateral: 1.48+-3.30) were insignificant. There was no graft damage during screw insertion or grafttunnel mismatch. We concluded that this modified technique allows simplified, reproducible tunnel and interference screw placement.

This study was undertaken to observe the mutagenic occurrence in urine excreted after the ingestion of roast beef. Two healthy nonsmoker persons of both sex were selected for this test, employing two strains (TA98, TA100) of Salmonella typhimurium according to Ames' method. The mutagenic activity began to appear in urine of both sex three hours after ingestion of 300 g of roast beef, gradually increasing until 6 hours and declining thereafter.

True hermaphroditism is a condition in which both an ovary and a testis or a gonad with histological features of both (ovotestis) is present in same individual. We present a case of 16-year-old true hermaphroditism who had an ovotestis on both gonad and female internal organs, such as fimbria. fallopian tube, uterus in the left scrotum after bilateral scrotal exploration. The patient's sex was reassigned to the male according to sex of rearing and gender role and managed with removal of ovotestis and female internal organs, bilateral subcutaneous mastectomy.

BACKGROUND: To find out characteristics and classification of toxic agents by clinical analysis of pediatric poisoning and to determine the clinical availability of grading by using MSPC score. METHOD: Subjects were patients under 15 years exposed to toxic agents, who visited Ajou university hospital emergency center from June, 1994 to October, 1997. The study was performed retrospectively. RESULTS: The subjects were 126 cases and male to female sex ratio was 1.2:1. Mean age was 29+/-30 months old. The most common route of exposure was ingestion, following contact, inhalation and bite. The most common reason was mistake by the patient, following mistake by caregiver, suicide attempt and accident. The MSPC score distribution of symptomatic patient was as follows; 1 point: 26 cases(63.4%), 2 point: 12 cases(29.2%), 3 point: 1 case(2.4%), 4 point: 2 cases(4.8%). The classification of exposed poison was as follows; therapeutic drugs: 29 cases(23.0%), non-therapeutic drugs: 97 cases(73.0%). The most common exposed poison was household products: 23 patients(18.3%) were admitted to hospital. CONCLUSION: There was statistically significant difference in the classification of poison, MSPC score, treatment modality at hospital, first follow up period after discharge between admitted group and non-admitted group. There was statistically significant difference in the reason of exposure, route of exposure, MSPC score, admission period according to patient's age. severity grading according to MSPC score is regarded as an available method to determine the modality of management.
