In femorsl neck fracture, viability of the femoral head depends on the revascularization of the femoral head. The purpose of this study is to observe the effect of early fixation and anatomical reduction by measuring the Tc-99m-MDP uptake ratio of the femoral head in experimental animsls. Femoral neck region of 20 mature rabbits were osteotomized completely and divided into 2 groups ; each group consisted of 10 rsbbits. Group 1 had two Kirschner wire fixation after osteotomy and anatomic reduction. Group 2 had no fixation after osteotomy. The uptake ratio of Tc-99m-MDP of the femoral head in each group were measured st the intervals of 24 hours, 48 hours, 1 week, 2 weeks, 3 weeks, and 4 weeks, respectively. The results obtained were as follows ; 1. In experimental group 1, the mean uptake ratio of the femoral head was 0.72±0.13 at 1 day after operation, increased to a level of 1.44±0.14 at 1 week, increased to a maximal value of 2. 90±0.36 at 3 weeks and decreased to a level of 1.10+0.12 at 4 weeks. 2. In experimental group 2, the mean uptake ratio of the femoral head was 0.70±0.10 at 1 day, 0.64±0.13 at 1 week, decreased to a maximal value of 0.33±0.05 at 3 weeks and 0.47±0.05 at 4 weeks, showing decreased level below 1.0. The results suggest that early anatomicsl reduction and rigid fixation of femoral neck fracture is helpful for revascularization of the femoral head and prevention of non union.

Malignant osteoblastoma is very rare tumor which shows histological findings of an aggressive pattern and benign clinico-radiological features, and also called as aggressive or pseudomalignant osteoblstoma. The authors experienced one csse of malignant osteoblastoma involving diaphysis of left humerus in 22-year old man. The patient is healthy and maintains his normal activity without recurrence over five years after complete excision of cystic mass, curettage and bone graft.

In carpal injury, a good functional end result seems to correlate with final anatomic alignment of carpus after treatment. Some cases are often misdiagnosed and result in inadequate treatment. Forty six cases of carpal injuries were analysed which were treated for 9 years from 1975 to 1984 at the Department of Orthopedic Surgery, Seoul National University Hospital. The observations can be summarized as follows. 1. The male to female ratio was 3.5: 1 and 82% of total cases were in the third and fourth decades. 2. The most frequent cause of injury was fall from height with outstretched hand. 3. Trans-scaphoid perilunar dislocation and its variant were the most common diagnosis in this analysis. 4. All of the scapho-lunate dissociation showed volar flexion intercalated segmental instability with scapho-lunate gap more than 2 mm in our series. 5. In 11 cases of trans-scaphoid perilunar dislocation and its variant, carpal collapse was found in 10 cases. In 5 cases dorsiflexion intercalated segmental instability pattern and in one case volar flexion intercalated segmental instability pattern were found to be present. 6, There was an increase in scapho-lunate angle in all cases of dorsiflexion intercalated segmental instability, but a decrease in scapho-lunate angle is not a consistent finding in volar flexion intercalated segmental instability. 7. In 24 cases more than 6 months follow-up, excellent and good results were obtained in 20 cases. 8. As a result of above findings, authors conclude that scapho-lunate gap more than 2mm has diagnostic value in scapho-lunate dissociation but that dorsiflexion intercalated segmental instability or volar flexion intercalated segmental instability only means the changes in the relationship between carpal bones and does not have definite or specific diagnostic value for a specific carpal injury.

Plexiform neurofibroma is considered a pathognomic of Von Recklinghousen's disease, which involves the deep and large nerve trunk. These are large irregular nerve fascicles which result from an increase in endoneural matrix within individual nerve facicles, without an increased number of nerve fibers. We experenced a case of Von Recklinghausen's disease in a 24 year-old male who had variable cutaneous skeletal, and CNS lesions. He presented multiple neurofibromas, cafe-au-lait spots, and axillary freckles as common cutaneous lesions of NF-I and giant pigmentation, sacral hypertrichosis, and plexiform neurofibroma as unusual cutaneous lesions. Also he had a scoliosis, bowing deformity of the humerous and wedging deformity of the body of the 5th cervical spine as a skeletal manifestation and cortical calcification in the occipital area as a CNS manifestation.

Pneumomediastinum is a relatively uncommon, infrequently reported entity, In the evaluation of these entity, it is important to exclude pathological causes, including Boerhaave's syndrome which carries a high mortality. Spontaneous pneumomediastinum is related to excessive intraalveolar pressure leading to rupture of perivascular alveoli in the setting of a Valsalva maneuver without communication to gut material. So, it has a benign self-limited course and rarely requires medical intervention. On the contrary, secondary pneumomediastinum caused by instrumental, traumatic, and spontaneous perforation of esophagus. Although the prognosis have been improved since the advent of broad-spectrum antibiotics and nutritional support, pneumomediastinum due to esophageal perforation still has a high morbidity and mortality. The most important prognostic factor is the time interval between perforation and initiation of therapy, and an awareness and a high clinical suspicion is critical in the early diagnosis and treatment. Recently, we have experienced 2 cases of pneumomediastinum, one case was spontaneous pneumomediastinum and the other may be caused by instrumental esophageal perforation. We report the clinical course of the patients with a current literature review.

Three cases of giant pituitray adenoma are reported. Two cases were operated by transsphenoidal approach and a case by transcranial approach. Transsphenoidal approach showed satisfactory results despite of marked suprasellar extension of tumors. We report rare giant pituitary adenomas with review of relevant literatures.

To evaluate the results of bilateral recession in large angle exotropia we examined medical records of 73 patients who had exotropia larger than 35PD and underwent bilateral lateral rectus recession. The mean of follow-up period was 16months. Successful alignment, defined as a final alignment of orthophoria, esotropia less than 5PD or exotropia less than 10PD was achieved in 44 patients(60.3%). There were no differences in age, refractive error, preoperative angle of deviation, prevalence of amblyopia, the presence and concurrent correction of vertical or cyclodeviation, the development of diplopia and the duration of follow-up period between the successful alignment group and failure group. The esodeviation on postoperative one-day tended to ensure a more satisfactory result, but it was not statistically significant. There were no statistically significant differences in stereoacuity and postoperative angle of deviation among the different fusional ability groups. The stereoacuity and postoperative angle of deviation did not show a positive correlation. However, on the two separate examinations of the stereoacuity and fusional ability, the latter results showed improvement in both parameters. This result suggests that the correction of exodeviation may play a role in improving binocular visual function in patients with large angle exotropia.
