We have made a statistical survey on 2441 amputated limbs of 2150 patients who were treated at the Depart- ment of Orthopedic Surgery and who were prescribed the prosthetics at the Prosthetic Center of Veterans Hospital from Mar. 1972 to Feb. 1982. 1. The peak incidence was in the age group from 21 to 30 years with 1546 cases (63.3%). Of 2150 patients only 9 patients were female. 2. The main causes of amputation were trauma with 1901 cases (77.9%), vascular insufficiency with 326 cases (13.4%) and chronic osteomyelitis with 157 cases (6.4%). And the most fre#quent cause of traumatic amputation was explosive injury with 1080 cases (56.8%). 3. Of the 2441 amputated limbs, 1756 cases (71.91°) were at the lower extremity and the most frequent site was below the knee with 1000 cases (57%). 4. Minor limb amputation was performed on 326 cases (13.4%). 5. Multiple limb amputation was performed on 255 patients (11.9%) and of these 12 patients were amputated on 4 extremities. 6. Reoperation was performed on 420 cases (17.2%). It was most prevalent in the lower extremity with 365 cases (86.9%) and their main cause was neuroma with 171 cases (40.7%). The most frequent site was below the knee with 240 cases (57.2%).

The size and configuration of the lumbar spinal canal constitute one of the important factors in the production of symptoms referable to cauda equina and nerve roots of the lumbar spine and the narrowness of the spinal canal. Numerous attempts have been made to measure the size of the lumbar spinal canal, but most of those are not sufficient to measure the oblique diameter of the lumbar spinal canal. Also, echographic diagnosis is much simple, safe, less expensive and non-invasive and furthermore demonstrates much more accuracy than other alternative and radiographic procedures. The purpose of this study is to establish the range of normal values of the oblique diameter of the lumbar spinal canal in Korean Army-aged group by echographic method in the interest of facilitating clinical evaluation of the lumbar spinal canal stenosis. The author measured oblique diamenter of the lumbar spinal canal in thirty healthy persons of both sexes of ages between nineteen and twenty-five years by ultrasound using sonolayergraphy model SSL-21A. Distance from the ligamentum flavum to the posterior longitudinal ligament was measured in millimeters with dial vernier caliper. Actual distance of oblique diameter of the lumbar spinal canal is obtained by multiplication of the distance of echogram by calibration factor 2.22. The results were as follows; 1. The mean values of the oblique diameter of the lumbar spinal canal in male and female between nineteen and twenty-five years of age were 14.77±0.85mm and 14.87±0.82mm in Ll, 13.99±0.87mm and 14.13±0.96mm in L2, 13.40±0.69mm and 13.71±0.75mm in L3, 12.88±0.69mm and 12.93±0.68mm in L4, 14.58±0.79mm and 14.42±0.84mm in L5 respectively. 2. The oblique diameter of the lumbar spinal canal was the widest at the first lumbar vertebra, the next at the fifth lumbar vertebra and the narrowest at the fourth lumbar vertebra. 3. There was no difference of diameter of the lumbar spinal canal between both sexes.

A 63 Year-old-lady has had substernal chest pain on exertion for 8 years. The chest pain has been increased over the last 3 years. A continuous murmur was heard at the left second to third inercostal spaces along the left sternal border. The electrocardiogram showed the inverted T-waves in the precordial leads. The right heart catheterization revealed 5% oxygen step up between RV and PA. The right sided pressures were normal. The coronary arteriography revealed markedly tortuous vessels starting shortly after the left main stem coronary artery was normally originated. One of the large vessel was shown to be drained into the pulmonary artery. In the operation room, without using heart-lung machine this abnormally drained vessel was simply ligated at it's draining site into pulmonary artery. After the operation the patient is feeling well with little symptoms and the continuous murmur is no longer heard.

From May, 1978 through Oct., 1979 the effect of Coenzyme Q10 was evaluated on 10 patients with chronic heart failure. The subjects selected for this study consisted of 7 patients with cardiomyopathy and 3 patients with valvular heart disease admitted to Severance Hospital, Yonsei University College of Medicine, All these patients had symptoms and signs of congestive heart failure which was stable for at least one month before starting Coenzyme Q10. Coenzyme Q10 was administered 30mg daily for eight weeks, one hour before meal and in combination with digitalis and/or diuretics. The drug effects were determined by measuring the cardio-thoracic ratio by chest X-ray, the sum of 'S' wave in V1 and 'R' wave in V5 in electrocardiogram, and PEP/LVET (pre-ejection period/left ventricular ejection time) by simultaneous tracings of carotid pulse and phonocardiogram every two weeks during medication. The cardio-thoracic ratio was improved in 4 of 10 cases, the sum of RV+SV5 was decreased in all 5 cases who showed voltages above 40mm before medication, and PEP/LVET ratio was decresed in 4 of 10 cases. The difference of average values before and after medication were not statistically significant(p<0.05) in all 3 parameters when examined by t-test. During treatment, there was improvement, if any, from two weeks after medication and no significant side effects were noted throughout the study period.

Twenty nine cases of segmental tibial fracture were treated at Ewha Womans University Hopital, Department of Orthopedic Surgery, during the period from January, 1970 to December, 1984. The following results were obtained. 1. Most common fracture level was type I, high middle segment, occurred about 12 cases (41.4%). 2. In view of the higher incidence of open fracture (16 cases, 55.1%) and comminuted fracture (22 cases, 75.9%), fracture was caused by high velocity. 3. Various external and internal fixation methods were applied, but higher union rate was seen in the cases of Küntscher nailing and plating with bone graft. 4. Excluding the cases of type V, average union rate was 28.5 weeks and open fracture (ave. 29.6 weeks) required more longer union rate than closed fracture (ave. 26 weeks). 5. Higher rate of complication (21 cases, 72.4%) was noted than other types of tibial fracture. 6. Good result was obtained for treatment of 5 cases of delayed union or non-union by plating and bone graft than any other methods.

Background: Endoscopic forehead lift effectively corrects brow ptosis, and is less invasive and has fewer complications than classic forehead lift. Therefore, endoscopic procedures are often used instead of making a coronal incision. However, very few studies have investigated changes in the height of the hairline and documented exact values regarding the extent of forehead elongation after these procedures. Therefore, we conducted this study to determine the degree to which the height of the forehead changes after endoscopic forehead lift. Methods: Patients’ medical records were retrospectively analyzed and measurements of clinical photography were made to investigate changes in the height of the forehead after the procedure. Subjects were divided into an experimental group (n=33) and an age-matched control group (n=33) for analysis; the experimental group comprised those who underwent endoscopic forehead lift from January 2015 to March 2018, and the control group comprised those who underwent upper blepharoplasty without forehead rejuvenation from July 2009 to September 2017. Results: The changes between the preoperative and postoperative height of the forehead in the experimental group were not statistically significant (right, P=0.163; left, P=0.256; midline, P=0.545). However, the changes in the height of the forehead in the control group were statistically significant on the right side (P=0.026) and left side (P=0.028), but not at the midline (P=0.244). Conclusions We investigated the extent of forehead elongation that occurred in cases of endoscopic forehead lift and verified that significant forehead height changes did not occur after endoscopic forehead lift.

Background: Dimples on the cheeks can make the smile look more cheerful and attractive. Therefore, some people who do not have dimples may choose to undergo dimple creation surgery. Although dimple surgery is quite common, those desiring this procedure often lack information about it. Therefore, we conducted the present study to share our surgical tips and clinical experiences regarding safe dimple creation surgery. Methods: This study included 2,048 patients who underwent dimple creation surgery at our plastic surgery clinic between April 2010 and June 2014. These patients were selected from those who displayed no scarring from injury or tumor removal in the central face during the presurgical evaluation. Medical records were used to identify the age and sex of each patient, the location of dimple creation, any postoperative complications, reoperation, and the reason for reoperation. Results: Of the 2,048 patients, 159 (7.7%) underwent reoperation. The reason for reoperation was undercorrection in 78 cases (49.0%), disappearance of the dimple in 62 cases (38.9%), and overcorrection in nine cases (5.6%). Five patients (3.1%) had their stitches removed to eliminate the created dimple because they changed their minds, and five patients (3.1%) had their stitches removed because of infection. No patients reported complications after reoperation, and no other complications, such as hyperpigmentation or foreign body reaction, were observed. Conclusions Safe surgery with minimal complications and satisfying cosmetic results can be achieved via accurate knowledge of the relevant anatomy and its relationship with dimples, as well as appropriate surgical methodology.
