Calcaneus is the largest tarsal bone and serves weight bearing of the body. The calcaneus has a pattern of cancellous bone enclosed with a very thin cortical shell. It is difficult to reduce the bony fragments accurately when there are comminution and displacement on the calcaneal fractures. Retrospective study was carried out of 18 patients(21 feet) of calcaneus fractures after axial fixation in Soonchunhyang University Hospital from July, 1982 to July, 1988. Minimum follow up period was 8 months(average 2 years 6 months). The clinical analysis of them are reported with a review of the literature and the results are follows:l. According to the Rowe's unit system, the results of treatment were excellent or good in 9 cases of 13 tongue types and 5 cases of 8 joint depression types. 2. The results were satisfactory in the calcaneal fractures of well reestablished Bohler angle to 21-30 degrees. 3. The results were excellent or good in 5 cases operated within post-trauma 1 week and in 9 cases operated from 1 week to 2 weeks. 4. The results were poor in the 2 joint depression type with severe comminution. And subtalar joint fusion was performed on the previous 2 cases. Then pain on the lateral malleolar area was subsided.

Malignant neuroepithelioma is a rare neoplasm arising within the peripheral nervous system and usually occurs in the lower extremities. It may involve patients in any age group and have no gender predisposition. In adolescents and adults the tumor must be distinguished from other malignant round-cell tumors. The poor prognosis and the need for aggressive, combined surgical and chemotherapeutic modalities in treating this tumor necessitate a prompt and accurate diagnosis. Authors have experienced a case of malignant neuroepithelioma developed in left sciatic nerve. The diagnosis was confirmed by CT scan, M.R.I., light and electron microscopic findings.

Authors treated 86 cases of patella fracture during 3 year period from June 1989 to March 1992 at the Dept. of Orthopaedic surgery, Soonchunhyang University. Forty cases of patella fracture showed hypertrophy of longitudinal and transverse diameter of patella during follow-up which were checked by simple radiographs. Completely documented cases were only forty-six, which were followed more than a year and preop. and postop. and final follow-up radiographs were reviewed. Authors measured longitudinal and transverse diameter of patella using preop. and postop and final simple radiographs to observe the morphological changes of patella after treatemnt. The purpose of this paper is to observe. 1. How much the patella was hypertrophied. 2. What kind of factors influence the hypertrophy of the patella, 3. What is the clinical correlation between the hypertrophy of patella and the clinical outcome. The results were as follows 1. Average hypertrophy of longitudinal and transverse diameter were 1.0±2.3mm and 2.5±1.2mm respectively. 2. Only fracture type(simple. vs comminuted.) was significantly related with the changes of longitudinal and transverse diameter of patella(p < 0.1), Other factors(cast immobilization period, operation method and age) show no significant relationship statistically(p>0. 5). And there is no relationship between longitudinal and transverse diameter statistically(p>0.4). 3. Those who showed change of longitudinal diameter between 0-10mm had good knee joint motion(99°±2). But those who showed shortening or lengthening over 10mm of longitudinal diameter had poor knee joint motion(37°±3, 60°±8 respectively). And change of transverse diameter was not related with the clinical result (p>0. 7).

OBJECTIVE: To determine the reproductive outcomes of women undergoing microsurgical reversal of tubal sterilization at age 36 years or older. MATERIALS AND METHODS: A series of 133 patients who received microsurgical reversal of the previously sterilized fallopian tubes at Seoul National University Hospital from July, 1980 to January, 1992 was reviewed and evaluated for clinical characteristics, pregnancy rates, and factors influencing the outcome of tubal reversal. RESULTS: Of 133 patients, 78 (58.6%) had been sterilized by laparoscopic cautery. Loss of children was a leading cause for tubal reversal. The mean interval from tubal sterilization to tubal reversal was 65.0 months. The overall pregnancy rate was 52.6% (70/133), and the mean interval was 9.4 months from tubal reversal to pregnancy. Excluding 7 patients who were lost to follow-up, 76 pregnancies were confirmed in 63 patients with the delivery rate per patient of 66.7% (42/63). There were no significant differences in age, duration of tubal sterilization, postoperative tubal length between pregnant and non-pregnant groups. CONCLUSIONS: Microsurgical reversal of tubal sterilization could be a justifiable method in women 36 years age or older.
