The cruciate ligaments are important in providing the anterior and posterior stability and usually associated with other ligament injury of the knee joint, and there are many controversies in its treatment. In general, the primary repair for the acute cruciate ligament injury was good, but some had opposite opinions in the treatment of the isolated anterior cruciate ligament injury. In acute injury, early repair of ligament and in delayed case, the reconstrution surgery of ligament was recommended. For good results, it is very important to give prompt management. Authors studies 23 cases in 16 patients with acute cruciate ligament proper injury who were treated by multiple pull out technique at the department of orthopaedic surgery, Chungnam National University Hospital from April, 1984 to July, 1988. The results were as followings: 1. The incidence was high in active male patients. 2. The most common injury was the traffic and automobile accident. 3. the tibial and femoral attachment were the most common detachment site in anterior and posterior cruciate ligament injury, respectively. 4. Isolated cruciate ligament injury was rare. 5. The results were good in 11 cases(47.8%), especially treated within one week.

Partial trisomy 10q syndrome is a rare chromosome anomaly characterized by severe mental and growth retardation, craniofacial dysmorphia with prominent forehead, fine arched eyebrows, deep set small eyes and micrognathia, In addition, other physical manifestations have been reported as skeletal anomaly, congenital heart disease, inguinal hernia, and so on. We report a case of partial trisomy 10q syndrorne with certain stigmata which confirmed by chromosome analysis.

The morphologic abnormalities of the endocrine pancreas that underlie persistent neonatal hyperinsulinemic hypoglycemia and are included under the heading "nesidioblastosis" appears to be heterogeneous. This characteristic morphologic finding is ductuloinsular complexes showing endocrine cells budding off the ductoepithelium and merging with adjacent endocrine cell clusters. A case of nesidioblastosis associated with hyperinsulinemic hypoglycemia occurred in a 6/365 year-old male neonate. Microscopic finding of near totally resected pancreas revealed irregular sized islets and ductuloinsular complexes, both of which contained hypertrophied B cells with a few mitosis. Because of persistent hypoglycemia after first operation, he received second operation 8 days after. This histologic finding was more severe comparative to that of first operation. According to these findings, the pathogenesis of nesidioblastosis may be congenital or developmental defect of a kind of compensatory mechanism by unknown stimuli to acquire persistent hypoglycemia.

This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

This study was performed to establish a radiological indication and contraindication of indirect decompression in the thoracolumbar burst fracture as well as to clarify an acceptable degree of the canal constriction to enhance neurologic recovery and to prevent the spinal stenosis. The canal diameter ratio (CDR) of the constricted level was determined using pre-and post-operative CAT images of 31 thoracolumbar burst fractures, decompressed indirectly. The acceptable CDR was decided by the lower limit of the 95% confidence interval of the post-operative CDR in cases without neurologic deficit associated with the canal constriction. A radiological indication and contraindication of indirect decompression was establish based on the calculation of the discriminant equation and linear regression equation respectively. The results were as followings. 1. The acceptable CDR was 46% at the cauda equina level and 37% at the conus medullaris level. 2. According to the result of calculation of the regression equation, the radiological contraindication of indirect decompression was the pre-operative CDR of 13% or less at the cauda equina level and 27% or less at the conus medullaris level. In conclusion, the radiological indication of indirect decompression was the pre-operative CDR of 34% at the cauda eqbina level and 42% at the conus medullaris.
