Supracondylar fracture is the most freqent injury of the elbow and frequently accompany complications in children. This injuries require meticulous care during first week period for the prevention of complications. Sixty cases of supracondylar fracture in children treated and managed at the Orthopedic Surgery, Taegu Presbyterian Hospital during the period from 1962 to 1970 The most cases were treated conservatively and various method of treatment were adapted according to the condition of the fracture. All obtained satisfactory bone union but six cases of them resulted gun-stock deformity (reversed carrying angle) of the elbow, Two of these underwent supracondyIar wedge osteotomy and gained satisfactory corrections.

Acrocephalosyndactyly is one of the more unusual and interesting errors of nature (Congenital anomaly) found in the human race. This syndrome was first described by Apert in 1906. Since that time, over 200 cases have been reported. The purpose of this article is to report an additional case along with review of provious literatures.

A case of amelia, which affected upon both lower extremities, was experienced at the Taegu Presbyterian Hospital. We report this case because of rarity of amelia and an addition of the case with brief review of literatures.

Twenty three leprous wrist drop hands had been operated for reconstructive surgery at the department of orthopedic surgery Presbyterian Hospital during the period from 1965 to 1972. The follow up study was carried out on twelve hands from six months to 82 months and was evaluated by the following assessments. 1. Function 2. Appearance 3. Environmental use and patients satisfaction in result The results were as follows 1. Satisfactory result was 84.1% in function, 66.7% in appearance, 75% in environmental use and patients satisfaction, and 75.3% in overall total assessment. 2. As complication, a case of adhesion of the transfered tendon was noted. 3. Preoperative and postoperative physiotherapy contributed an important roll in the end results.

Fractures of the femoral neck in children are rare and usually occur as a result of severe trauma. They are one of the most challenging injuries to treat. Their complication rate is high and their anatomic and physiologic characteristics make treatment difficult. The commonly encountered complications are avascular necrosis, nonunion, coxa vara and premature fusion of epiphyseal plate. Treatment of these fractures remains an unsolved problem but accurate reduction held with adequate internal fixation would appear to offer the best chance for succesful results. We report our observations in the treatment of eighteen cases of fracture of the femoral neck in children. Included is a review of references. The results obtained are as follows: 1. Among 18 patients, 11 were boys and 7 were girls. the highest incidence was between the ages of 5 and 7 years. 2. The main causes of fractures were traffic accidents in 10 cases (55.5%), falling from a height, and slipping down. 3. The commonest type of fracture was the cervicotrochanteric type (47.4%). Twelve cases were displaced fractures (66.7 %). 4. The range of Pauwels angle varied from 20° to 70°. 5. The commonly associated injuries were pelvic bone fractures, extremity fractures, skull fractures and soft tissue injuries. 6. Nine cases were treated by skin traction and plaster cast. Five cases ere treated by closed reduction and internal fixation with K-wires or knowles pins. 7. In 13 of the 18 cases, follow-up studies were done for an average period of 18 months. 8. The results were analyzed according to the Ratliffs assessment. Among the 13 cases, 10 cases showed good results, two fair and one poor. 9. All cases treated by closed reduction and internal fixation showed good results without complications. 10. Complications developed in five cases (38.5%), three cases of avascular necrosis and two cases of coxa vara. Among these five cases, one case of avascular necrosis developed as a result of neglect of the fracture and the others as a result of too conservative a treatment. 11. Secondary treatment of trochanteric arthroplasty was required in only one neglected case. This was further by avascular necrosis and the results were poor. 12. As a result, we recommond closed reduction and internal fixation as the most favorable method of treatment for the fracture of the femoral neck in children.

Dental restorative materials must have the physical properties to withstand wear and corrosion. Base metal alloys possess better mechanical properties and lower price than the gold alloys. For these reason such alloys have largely replaced the precious metal alloys. One aspect to consider is the release of metal substances to oral environment. The release of elements from dental alloys is a continuing concern because the elements may have the potentially harmful biological effects on local tissue. The purpose of this study was to minimize metal release on the nonprecious metal surfaces by ion bea assisted deposition(IBAD) of titanium nitride (TiN). Ni-Cr-Be alloys with and without TiN coatings were secured in an wear test machine opposing ruby ball to determine their relative resistance to wear with 100m, 200m, 300m and 400m sliding distance. And the corrosion behavior of the Ni-Cr-Be alloys with and without TiN coating and 3 dental noble alloys have been studied. Potentiodynamic curves were used to analyse the corrosion characteristics of the alloys. The measurement of the released Ni and Ci ions was conducted by analysis of the electrolyte solution with atomic absorption spectroscopy. The results were as follows : 1. The critical sliding distance that wore down TiN coating of 2.5micrometer thickness in this study condition was 300m. 2. Ion beam assisted deposition of TiN showed a good surface modification with respect to the properties of wear and corrosion resistance. 3. X-ray diffraction showed that the strongest peak of TiN(111) in the coatings. 4. The release of Ni and Cr ions from alloys measured by means of atomic absorption spectroscopy was reduced by ion beam assisted deposition of TiN.

The effect of pancuronium on induced hypotension by histamine and d-tubocurarine was investigated in the rabbit. The results are summarized as follows; 1) Intravenous diphenhydramine(5ug) pretreatment attenuated the arterial hypotension induced by 3ug of histamine and 30ug of d-tubocurarine. 2) Pancuronium in doses of 1ug, 3ug, 10ug and 30ug produced an attenuation of the vaso depressor action of histamine 3pg but was not does dependent and the depression rate was 20%, 25%, 24% and 49% respectively. 3) Pancuronium in dose of 0.3ug, lug, 3ug and 10ug produced to attenuate the vasode-pressor action of d-tubocurarine 30ug, which it was dose dependent attenuation of vasode-pressor action at dose from 0.3ug to 3ug and depression rate was 19%, 26%, 52% and 20% respectively.
