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.

Total release of the hamstrings of the knee from their origin was performed In nine cerebral plasied children. Eighteen procedures were performed in nine patients whose age ranged from three to sixteen years with an average of ten years. The average follow-up period was twenty one months from ten to thirty-six months. The spastic knee flexion was correction adequately; in mest instances the crouch posture was corrected, gait was improved, and a long stride was possible. The power of the hamstrings was assessed in the fourteen limbs of the children who could walk or cooperate in musicle testing. The power was graded as good in six knees and as normal in one. Seven showed improvement in gait; six patients who had never walked were able to do so after hamstring release; and one patient was able to stand up for the first time in his life after the operation. Eight out of nine cases are now able to stand up with or without support of a brace, and to walk with a brace in five cases and without support in two. However, increased lumbar lordosis and genu recurvatum has occurred in two cases each.

Computed tomography is helpful in delineating the extent and configuration of pelvic fracture. These injuries are frequently complex, and the precise pathologic anatomy is not easily demonstrated by conventional radiographs. In some case CT will reveal a fracture which may not be seen on the radiograph. In addition, the extent of soft tissue damage and joint involvement is precisely demonstrated with CT. The twenty-three patients admitted to our Inchon Christian Hospital with pelvic fracture with or without hip dislocation from October 1981 to October 1984. We could assess the applicability of C-T scan in pelvic fracture and the following conclusions were obtained. 1. The axial plane of CT was shown to be the most suitable for evaluation of pelvic fracture. 2. C-T could detect the pattern of hip fracture including degree of fracture fragment displacement, and rotation, hip joint stability, intra-articular osseous fragment and interposed soft tissues in hip joint. 2. C-T permitted better evaluation of associated injuries in soft tissue and viscera on the pelvic and retroperitoneal cavity, and also gave information about other associate fractures. 4. C-T was more sensitive than plain radiography in detecting fracture involving the sacrum, quadrilateral surface, acetabular roof, and posterior acetabular hip.

Authors observed two cases in which the formation of glass-like hyaline membranes in the anterior chamber caused by birth trauma. Case 1 revealed a curtain-like glass membrane in the anterior chamber with a central nubecula corneae of right eye (Fig. 1). Case 2 revealed two paralled glass membranes and its stripes extended across the anterior chamber attached at each extremity to the posterior surface of the cornea (Fig. 2).

BACKGROUND: Recently, cardiopulmonary exercise testing (CPX) has become a popular diagnostic method for differentiating the main cause of exertional dyspnea or exercise limitation. We evaluated the difference in the CPX results according to interpretative algorithms and the methods of exercise in Korea. METHOD: Sixty-six patients with chronic lung disease and 48 adults with dyspneic symptoms, but with no abnormalities in a spirometry performed symptom limited CPX, were included in this study. The results were interpreted using both Wasserman's(WA) and Eschenbacher's algorithm (EA), and a comparison between both algorithms was made. Thirty-three healthy medical students performed the CPX with a cycle ergometer and treadmill. The results were interpreted with EA and the concurrenec in interpretations was evaluated according to the methods of exercise. RESULTS: 1. In patients with chronic lung disease, the overall concordance rate between the two algorithms was 63.6%. The concordance rates were 69.8% in patients with obstructive, 25.0% in those with restrictive, and 66.7% in those with mixed pulmonary insufficiency. In patients with dyspneic symptoms but normal findings in resting spirometry, the concordance rate was 60.4%. 2. In healthy medical students, in results interpreted with EA, the concordance rate between the cycle ergometer and treadmill exercise was 25.0%. CONCLUSION: Both interpretative algorithms and methods of exercise may affect the CPX results. In using CPX as a diagnostic test for the causes of dyspnea in the Korean population, the interpretative algorithms and method of exercise need to be standardized, and a predictive VO2max equation needs to be established.

PURPOSE: To evaluate the predictive factors of radiation pneumonitis (RP) and associated changes in pulmonary function after definitive concurrent chemoradiotherapy (CCRT) in patients with non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Medical records of 60 patients with NSCLC who received definitive CCRT were retrospectively reviewed. Dose volumetric (DV) parameters, clinical factors, and pulmonary function test (PFT) data were analyzed. RP was graded according to the CTCAE ver. 4.0. Percentage of lung volume that received a dose of threshold (Vdose) and mean lung dose (MLD) were analyzed for potential DV predictors. PFT changes were calculated as the difference between pre-RT and post-RT values at 3, 6, and 12 months after RT. RESULTS: Twenty-two patients (37%) developed grade > or =2 RP. Among clinical factors, tumor location in lower lobe was associated with RP. Among the DV parameters, only MLD >15 Gy was associated with grade > or =2 RP. There were statistically significant decreases in PFT at all points compared with pre-RT values in grade > or =2 RP group. MLD was associated with forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) changes at 6 and 12 months. V10 was associated with FVC changes at 12 months. V20 and V30 were associated with FEV1 changes at 6 months and FVC changes at 12 months. CONCLUSION: After definitive CCRT in patients with NSCLC, MLD >15 Gy and lower lobe tumor location were predictors of grade > or =2 RP. Pulmonary functions were decreased after CCRT and the magnitude of changes was associated with DV parameters.

Unfused olecranon epiphysis has been reported rarely. We found an unfused olecranon tip within joint and a few small spurs on the apposing olecranon fossa and removed it successfully through the arthroscope. We think that it is a part of secondary ossification center of the olecranon and tbat it was separated through the epiphyseal plate by repetitive impaction of the tip of the olecranon into the olecranon fossa during pitching. In conclusion, fusion of the intra-articular part(articular center) of the olecranon epiphysis can not occur by nature. Repetitive extension overload during pitching may cause symptoms, and could be treated with arthroscopic control.
