Since the independent reports of Charcot and Marie and of Tooth, in 1886, interest in this familial disease has centered largely in the genetic and diagnostic aspects, and yet references in the literature to Surgical management are rare and inexact. Our experience with Charcot-Marie-Tooth disease in 4 patients operated at Seoul National University Hospital during the last 3 years is reported. Of 6 cases of Charcot-Marie-Tooth disease which have been studied, 4 patients have undergone surgery for the correction or amelioration of the crippling foot deformity. The authors' operation has consisted of triple arthrodesis, medial release, lengthening of the Achilles tendon, tendon transfer which was available and present evidence that properly designed surgical treatment can correct, prevent, or materially reduce disability of the deformed feet. Of the 4 cases reported here, all have either been reviewed or the patients have been interviewed in the last year. On the basis of adequate follow-up observations, thesurgical procedure outlined have been shown to improve the crippled condition. In spite of progressive musele wasting, the operative treatment could prevent or ameliorate the deformity. Three cases of Charcot-Marie-Tooth disease were evaluated in a long-term follow-up after having undergone surgery to correct their foot deformity. Excellent results were achieved from three of them which were maintained at final follow-up, and one is being gollowed up.

In the treatment of dislocations and subluxations of the hip in the older children, whether congenital or paralytic, orthopedic surgeons are blessed with a wide variety of commonly used surgical procedures; namely, Salters innominate osteotomy, acetabtloplasties, Pembertons pericapsular osteotomy, shelf operations, Chiaris pelvic displacement osteotomy. and Colonnas capsular arthroplasty. However, with increasing age and soft tissue contractures,these procedures become ineffective, leaving a wide range of age between older children and young adults subject to uncertain or unfavarable prognosis. Steels triple osteotomy (1973) is aimed at coverig this age group, when displacement or in nominate osteotomy is either technically infeasible or likely to fail. It consists of an open reduction with or without soft tissue release and skeletal traction, redirection of the acetabulum to cover the femoral head by osteotonmies of the pelvis that has lost its young cartilagenous resiliency, and preservation and physiological remodelling of the articular cartilage of the acetabulum. We performed Steels osteotomy on a 21-years-old female with a severe paralytic subluxation of the hip associated with pelvic obliquity and paralytized both lower extremities. One and a half year follow-up result was satisfactory with a stable and congruous joint despite paralysis and with the patient walking for the first time in her life.

Fracture of the coracoid process are rare and those associating with a complete acromioclavlcular separation is even more rare. The mechanism of injury may be attributed to either direct or indirect trauma. Most coracoid fractures are minimally displaced because It is by maintained by the coracoclavicular ligament and coracoacromial ligaments. Usually good result is obtained In the coracoid fracture by non-operative treatment. On the other hand open reduction Is rarely Indicated. The case we are reporting was treated by open reduction and Internal fixation of the acromloclavicular joint using two Kirschner wires, and screw fixation was done for the fracture of the base of the coracoid process. Review of the literature ls also done.

The present study is an observation of 678 cases of children's fractures; which was treated in the Dept. of Orthopedic Surgery, inchon Christian Hospital, for the past ten years, from 1968 to 1978. The peak age was in from 5 years to 6 years. The sex ratio was 2.9 male to 1 female. The ratio between the right and left extremity was nearly equal. The frequency of fracture of the upper extermity was silghtly dominant then lower extremity. The cause of fracture was fall down Injury in nealy 70% of all cases. The epiphyseal Injury was noted as 16.8% of total orthapedic cases. The most common type of Salter & Harris Classiflcation was type II or 56.1%. Mostly all of children's fractures were treated by closed method, and others were treated by open reduction. Complication Included 29 cases of changed carring angle 18 cases of traumatic arthritis and 8 cases of malunlted supracondylar fracture and 3 cases of postoperative Infections and 2 cases of radial nerve palsy and 3 cases of delayed ulnar nerve palsy of the elbow. In fractures of the femur, 3 cases of the peroneal nerve palsy and 2 cases of leg longth discrepancy was noted. Brief discussion and review of Iiterature is presented.

Experiences of 26 cases of electrical bone stimulation on normal adult rabbits was documented in this paper. The cathodic electrode was introduced longitudinally into the medullary cavity of the proximal tibia and the anodic electrode was introduced transversely in the distal femur of the same side. The contralateral tibia was used as the control, of which the Teflon coated Kirschner wire was introduced longitudinally into the medullary cavity. 10uA of direct current was passed continuously through the fixed wires between the proximal tibia and distal femur. At the second, fourth and sixth week, random bone scan with 99m-Tc was performed and the animals were sacrificed. The specimen X-rays of the tibia and femur were taken and the specimens were prepared for the microscopic study. The followings are obtained from this experimental study. 1. The rate of new bone formation is 69.2% in the stimulated group and 7.7% in the control group. There were also fibrosis and cartilage formation as well as the new bone formation. The fibrosis and cartrilage formation are observed only in the electrically stimulated side and their occurances are 69.2% and 11.1% respectively. So The new bone formation and fibrosis are definitely increased in the bones of the cathodic electrical stimulation than those of the control side. 2. The intramembraneous ossification is the predominent feature of this electrically stimulated new bone formation. 3. Bone and soft tissue necrosis was the main microscopic feature in the anode side. 4. Since new bone, fibrous tissue and sometimes new cartilage were observed in this study, it seems that the cathodic electrical stimulation is not specific for the new bone formation, but induce crude tissues such as bone, cartilage, fibrous tissue or vessels. Furthermore, it can be postulated that the 10uA electrical stimulation is only one of the best electrical environment for the formation of the crude tissues, especially for bone and fibrous tissue.

To evaluate the relationship between spontancous diuresis and improvement of pulmonary function in respiratory distress syndrome, 15 premature neonates requiring mechanical ventilation for RDS, who admitted in NICU of Wonkwang University Hospital from January 1990 to June 1992, were studied. The results were as follows (results are mean+/-SEM) 1) Mean birth weight of study infants was 1.82+/-0.08Kg, and mean gestational age was 32.80+/-0.54 weeks. 2) The onset of diuresis occured at a mean age of 29.1+/-2.48 hours with maximum diuresis at a mean age of 41.9+/-1.8 hours 3) Mean urine output increased from 2.25+/-0.43ml/Kg/hr at the stage of pre 12 hours-onset of diuresis (p<0.001), then decreased 3.5+/-0.2ml/Kg/hr at the stage of after maximum diuresis (p<0.05). 4) After maximum diuresis, inspired oxygen gradient, peak inflating pressure, peak end expiratory pressure, mean airway pressure, and respiratory rate were decreased significantly (p<0.05), and alveolar-arterial oxygen gradient was decreased more significantly (p<0,01). So, We conclude that the pulmonary function was rapidly improving after maximum diuresis and these changes reflect the general principle used in ventilatory management of infants with RDS.

The optic canal fracture has been recognized as a clinical entity for quite sometime, and is, by no means, a rare condition. We were aware of it for last several years, and have collected five radiographically proved cases from the records. Interestingly enough, two of these patients were involved in motor-cycle accidents and revealed abrasion over the lateral end of the homolateral eye brow. Only one of these five patients had partial recovery of his vision.

During last 20 years from 1959 to 1978, 75 cases of the congenital pyloric stenosis were admitted to department of pediatrics of Yonsei University College of Medicine, and evaluated clinically. The results obtained are asfollows: 1.Vomiting is usually developed during 2 to 4 weeks of life(38 cases, 50%) and the ratio of male to female was 6.5:1. 2. The incidence among siblings were 37 cases in 1st born, 20 cases in 2nds and 9 cases in 3rds. 3. The duration from onset to admission showed a eak incidence between one to two weeks(41 cases among 75 cases) 4. In the symptoms and physical findings; Non-bile stained vomiting was developed in all of the cases, abdominal masses palpated in 67 cases(90%), and visible peristaltic waves were observed in 25 cases(33%). 5. Metabolic alkalosis was developed in 25 cases (33%), serum Na concentration was ranged between 130~150mEq/l in 59 cases and serum K concentration between 3~5mEq/l in 65 cases. 6. 70 cases received surgical treatment. 69 cases were improved, and one case was expired due to aspiration pneumonia. 4 cases were improved with medical treatment including anticholinergics.

PURPOSE: The purpose was to evaluate the procedure-related complications of the TIPS and its clinical significance. MATERIALS AND METHODS: The materials consisted of 52 patients who had 57 TIPS procedures for the management of variceal bleeding due to portal hypertension. To detect the occurrence of complications during transhepatic needle puncture(from hepatic vein to the portal vein), contrast material was injected with the withdrawl of the puncture needle. RESULTS: Procedure-related complications occurred in 28 patients (54%) among 52 patients. The corn lications were biliary tree puncture(15 cases), transperitoneal puncture(14 cases), stent malposition(3 cases) stent migration(1 case), hepatic arteries puncture(1 case), splenic vein perforation(1 case), and paroxysmal tricular tachycardia(1 case). Three patients had acute stent thrombosis with rebleeding immediately after procedure. The procedure was repeated in two patients. One patient was expired due to rebleeding. CONCLUSION: The procedure related complications were clinically insignificant in most instances, when stent thrombosis or proxysmal ventricular tachycardia was developed.
