Clinical observations of 11 cases of acute pyogenic osteomyelitls and 14 cases of acute pyogenic arthritis in infancy during past 11 years were carried out and following results obtained. 1. The highest age incidence was less than 3 months after birth (70.6%). 2. Average duration of symptoms was 7.8 days. 3. The most important underlying cause was multiple femorai vessel puncture (23.5%). 4. The chief symptom or sign on admission was pseudoparalysis or limitation of motion (82.4%), and local swelling (82.4%). But high fever on admission was present in only 29.4% of cases. 5. The femur was the most common site in acute pyogenic osteomyelitis (36.4%), and the hip joint in acute pyogenic arthritis (42.9%). 6. Leucocyte count was Increased more than 20,000/mm in 60.0% of the cases. Erythrocyte sedimentation rate was increased more than 21 mm/hr in 72.0% of cases. The positive result on bacteriologic culture was 76.0%. Coagulase-positive Staphylococcus aureus was cultured in 4 cases of acute pyogenic osteomyelitis and 5 cases of acute pyogenic arthritls. a-hemolytic Streptococcus was cultured in 2 cases of acute pyogenic osteomyelitls and 1 case of acute pyogenic arthritis. Hemophilus influenzae was cultured in 1 case of acute pyogenic osteomyelitls and 2 cases of acute pyogenic arthritis. 7. 45.5% of acute pyogenic osteomyelitis was combined with acute pyogenic arthritis. 8. The longer the duration of symptoms was, the longer the abnormal hematologic picture lasted. Erythrocyte sedimentation rate was the most accurate index of activity in acute infection of bone and joint. 9. Shortening or deformity due to epiphyseal plate damage occured in 1 case of acute pyogenlc osteo-myelitis, and 3 cases of acute pyogenic arthritis. Those complications could be minimized wlth early diagnosis and treatment.

Supracondylar osteotomy was performed on 78 knees in 65 patients with poliomyelitis for correction of deformities of the knee at the Department of Orthopedic Surgery, Seoui National Unlversity Hospital, during the 16 years from January 1963 to December 1978. Following observations were made from the review of statistics, technical problems, and complications of the operation. 1. The ages of the patients ranged from 4 years to 28 years, the average being 15 years. Two thirds of the patients were in the second decade. 2. 37 knees (47.4%) had flexion deformity, 19 knees (24.4%) flexion-valgus deformity, and 13 knees (16.7%) flexion-valgus-external rotation deformity. The amount of flexion deformity ranged from 7 degrees to 90 degrees, the average being 22 degrees. Valgus deformity ranged from 3 degrees to 25 degrees, the average being 12 degrees. External rotation deformity ranged from 5 degrees to 30 degrees, the average being 18 degrees. 3. The operative techniques employed were categorized into 5 types. The most common type was a closed wedge hinged osteotomy (Technique I), which was employed on 50 knees (64.1%). Satisfactory results were obtained by combining other procedures, when necessary, i.e. pre-operative skeletal traction, Yount fasciotomy, high tibial rotation osteotomy hamstring transfer and epiphysiodesis. 4. The time required for union was the shortests in the Technique 1 group, and longest in the Technique III group, a complete osteotomy with bone shortening. 5. The most common complication was stiff knee, which was encountered in 10 knees. Residual or recurrent deformity was observed in 4 knees, in 3 of which hamstring transfer was recommended but was not consumated. Delayed union was observed in 3 knees in the Technique II group (closed wedge complete osteotomy) and in 1 knee in the Technique III group. Nonunion occured in 1 knee in the Technique II group. The incidence of complications were higher in the Technique II and III groups, and lowest in the Technique I group.

Bone is a heterogenous and anisotrophic material exhibiting elastic, viscoelastis and plasticproperties. A considerable amount of information is now available regarding biomechanical properties and mechanisms of fractures of mature long bones, but less is known about the properties of the growing bones. In order to assess the biomechanical properties under tension, rabbits growing bones were loaded with Instron Modal 1,000 until fracture occurred. Two hundred tibiae of 100 New Zealand white immature rabbits were divided into 6 experimental groups according to maturity and size. Group I-R(40 right tibiae of 1-month old rabbits), Group I-L (40 left tibiae of 1-month old rabbits), Group II-R(20 right tibiae of 3-month old rabbits), Group II-L (20 left tibiae of 3-month old rabbits), Group III-R(40 rigth tibiae of 5-month old rabbits), and Group III-L(40 left tibiae of 5-month old rabbits). The following results were obtained. 1. Fracture type was transverse.or nearly transverse in 170 out of the total 200 tibiae(85%).

When a glaucoma filtering operation fails, the causes may be categorized as intraocular, scleral, or extraocular. Some authors have implicated that extraocular causes of failure are due to closure of the external opening by connective tissue. This histologic investigation was undertaken to examine the surgical wounds of 8 experimental subjects including 4 albino and 4 pigmented rabbits. Under general anesthesia by pentothal sodium, a single punch sclerectomy was performed on each right eye. A trabeculectomy was performed on the left eye. Seven and ten days following surgery, globes were removed and immediately fixed in Karnovsky's fixation solution. Following fixation, globes were bisected through surgical wounds, and one-half was studied using standard light microscopy. The other one-half specimens were blocked and processed for transmission electron microscopy. The results of the evaluations were as follows: 1. Full thickness sclerectomy wounds healed by ingrowth of fibroblasts from subconjunctival and episcleral tissue, but trabeculectomy wounds showed no communication with extrascleral tissue. 2. Quantitatively, proliferation of fibroblasts were more exuberant in the sclerectomied eyes compared to trabeculectomies. 3. There was no evidence of significant difference between albino and pigmented rabbits. 4. The granulation tissue composed mainly of fibroblasts resembles smooth muscle cell(myofibroblasts) and extracellular collagen constituents. Ultrastructurally, these cells showed massive bundles of intracytoplasmic microfilaments with scattered dense bodies, wrinkled and folded nuclei indicative cellular contraction, and abundant cisternae of rough endoplasmic reticulum informative activity of cellular proliferation. From those results, author conclude that smooth muscle antagonists may inhibit the proliferation of myofibroblasts after glaucoma filtering operations.
