Syringomyelia was described by Etienne, Morgagni and Santorini in 1594 for the first time and was named by Olliver in 1824. In spite of hundreds of years study, it's cause is still not distinctly known and symptoms are very much variable because of its wide, irregular lesion in the spinal cord. The patient of 34 years old male had been suffered from sensory and temperature dissociation and muscle weakness of lower extremity including lower trunk for two years. In case of classical syringomyelia, sense of pain and temperature were diminished on the same area but this patient had complained disturbance of pain and light touch on the same area, but temperature loss does not coincides with, as figure shows. This report will review syringomyelia of lumbosacral type with a case history and references which is relatively rare in incidences.

Voluntary habitual dislocation of the hip is very rarely reported in children, and only 13 cases have been reported in the literature. We add a new case in a 5 year old boy. The boy did not have previous history of trauma, skeletal and/or soft tissue anomalies, nor known connective disease. He was treated by intertrochanteric varusinward rotation osteotomy of the affected hip on February 25, 1985 and was followed until January 11, 1993. Postoperative convalescence was uneventfully successful, and the hip developed well without any obvious dysplasia at the latest follow-up.

Five adult cases of post-laminectomy swan-neck deformity are reported. The factors causing the deformity, prophylactic measures, and treatment of the deformity are discussed. It is strongly adviced to the neurosurgeons and orthopedic surgeons that they should be aware of this unwanted complication of the multi-level cervical laminectomies, and that they should provide every preventive measures before post-laminectomy swan neck deformity develops. Anterior interbody fusion spanning the entire unstable segments is preferably recommended together with application of pre-fusion traction.

Human untreated costal cartilage was compared with lyophilized human costal cartilage which was treated with defatting solution for 48 hours and freeze drying for 72 hours (-70degree C, 10??bar) on the tendency of distortion. All cartilages, which were taken from six cadavers, were carved 5x5x30mm in size on principle of the balanced cross section. Their distortions were evaluated by two methods at intervals of one week, one month, three months, six months after experiment. At first, the degree of distortion was grossly graded with four steps: grade O; no distortion / grade I; minimal distortion / grade II; moderate distortion / grade III; severe distortion. Second method is measurement and quantification of distortion in the horizontal and vertical plane of cartilage.Untreated cartilage is shown to be an unsatisfactory material, with only three(12%) of the 25 cartilages being cosmetically acceptable(grade 0 and 1) after 6 months. In lyophilized cartilage, 18(94%) of the 19 cartilages were cosmetically acceptable(grade 0 and 1) at 6 months. This figure is highly significant(p<0.01). In another method, distortion in the horizontal(h) and vertical (v) planes of cartilage were measured, and mean values of ???? were calculated. In untreated group, the mean values of ???? were 0.82 at 1 week, 0.91 at 1 month, 1.13 at 3 months, and 1.31 at 6 months. In lyophilized group, the mean values were 0.27 at 1 week, 0.29 at 1 month, 0.40 at 3 months and 0.47 at 6 months. All values were statistically significant(p<0.01).

Despite the progress in the treament of the subretinal neovascular membrane(SRNVM) by the development of laser photocoagulation, it has been reported difficult to manage with laser photocoagu1ation on which developed in high myopic eyes: first, their location in relation to the foveola is usually difficult to discriminate; second, subretinal neovascular m6mbrane developes very close to the foveola; third, the atrophic photocoagulation scar may extend to the foveola. The interferone alpha 2a has been known to suppress angiogenetic activity, and its application to subretinal neovascular membrane in high myopia has been suggested. The effect of interferon alpha 2a on neovascular membrane in high myopia was investigated by the authors. Subjects included 16 eyes with interferon treament and 12 eyes as control who had been followed for 3 months or longer. The median total dose in these patients was 75 X 10(6) units, given over a six- to eight-week period. In the interferon treament group, the activity of neovascular membrane decreased in 9 eyes(56%) and the visual acuity improved in 7 eyes(44%). In contrast, the control group showed a sustained activity of neovascular membrane and the visual acuity was improved in only one eye(6%). Therefore, interferon alpha 2a can be considered as an alternative method in the management of the some subretinal neovascualr membrane in high myopia which is resistant to the other treament.

Bony defect is one of the most common problems in craniomaxillofacial surgery. Although aurogenous bone graft is the best choice for the treatment of bone defect, it provides many problems such as donor site morbidity, irregular absorption, and limited amount of harvest. To overcome the shortcomings of autogenous bone graft many bone substitutes have been introduced. The ideal bone substitution is to have characteristics such as cheap, easy to obtain, rapid fusion to recipient bone, hard structure, long maintenance of shape and volume, low infection rate, and low exposure rate. Among those bone substitutes which have been widely used we chose lyophilized cartilage allograft because of low antigenecity, low resorption rate, easiness of carving and ling term preservation. From August 1993 to August 1997, 66 patients had been performed craniomaxillofacial reconstruction with lyophilized cartilage allograft. Orbital wall reconstruction and correction of enophthalmos were 24, correction of cleft lip and nose deformity were 19, temporal augmentations were 7, and others 16. Complications such as infection, exposure were not common. And partially removed cartilage was proved some calcification. Radiologic follow-up presented well positioned lyophilized cartilage allograft. Two radiologic works revealed haziness of bone density at the site of cartilage allograft. This suggests the ossification of lyophilized cartilage allograft. Together with liw infection rate, low exposure rate, and good framework for osteoconduction, lyophilized cartilage allograft are regarded as one of the good bone substitutes.
