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.

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.

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.

Basal cell carcinoma is the most common skin cancer, especially on the eyelid and nose. As it rarely invades to a underlying bone or metastasizes an distant site, and is usually found at an early stage, it is regarded as a curative disease. However, basal cell carcinoma on the eyelid and nose may be resected incompletely due to efforts to preserve important structures or as a result of esthetic considerations. We experienced two cases of basal cell carcinoma with local invasion to underlying bone. One was a recurred case on the nasal area extending to the nasal bone arts medial wall of the ethmoid sinus. The lesion was widely resected and covered with a radial forearm free flap. The other was on the eyelid extending to the orbit. It was treated with orbital exenteration and resection of the involved eyelid. The defect was reconstructed with the temporalis muscle flap with split-thickness skin graft. These patients were followed up for 7 months with no evidence of recurrence. Since basal cell carcinoma can invade to the bone and metastasize to a distance site, it should be resected radically in the regions of the eyelid and nose.

The use of pure titanium and titanium alloys have been increased recently in fixed, removable prosthodontics and implant fields as a framework. But when they were used for superstructures of implant of metal framework of removable prosthesis, welding is necessary to reconnect the fracture site to control the casting distortions. To overcome the difficulties in soldering the titanium due to high oxidation property, much effort have been devoted. In this study, some of mechanical properties were compared between pure titanium and Ti-6Al-4V alloy by usingl aser welding, electron beam welding technique and tungsten arc welding. Mechanical properties such as tensile strength, yield strength, elongation and microhardness were measured. And, in order to compare the effect of welding site and surrounding metal tissue according to the welding condition, SEM photographs were taken an element distribution was observed by Wave Dispersion Spectroscopy. Through analyses of the data, following results were obtained; 1. In items such as tensile strength, yield strength and elongation according to the welding techniques of pure titanium, only tungsten arc welded group showed significant lower value than other groups(P<0.05). 2. In items such as tensile strength and yield strength according to the welding techniques of Ti-6Al-4V alloy, control group and tungsten arc welded group showed significant difference among all the groups(P<0.05). 3. Ti-6Al-4V alloy exhibited significantly greater elongation than control group when the laser welding method and electron beam welding method were used, and elongation showed increasing tendency. 4. Pure titanium specimens exhibited increasing tendency of microhardness regardless of the welding technique applied, and especially tungsten arc welded group demonstrated a great increase of microhardness than parent metal. 5. There was no hardness change in laser welded group and electron bean welded group of Ti-6Al-4V ally, but in tungsten arc welded group, hardness changed greatly from parent metal to weld seam. 6. Through the metallographic examination and scanning electron microscopy, laser welding caused central fusion and recristallizations were formed and tungsten arc welding caused localized fusion to 0.3-0.7mm from the surface.
