The authors have studied 37 Korean embryos of Carnegie stage 11~23 and 18 fetuses to demonstrate the development of the shoulder joint. The external feature of the upperlimb bud is observed by stereoscope and camera, and the internal structures are studied by microscopic observation. The results obtained were as follows: In stage 12 upperlimb buds were appeared. In stage 17 mesenchymal condensations for humerus and scapula, and glenoid labrum were observed. In stage 19 one-layered interzone between the humerus and scapula was visible. In stage 22 three-layered interzone between the humerus and glenoid labrum was formed. In stage 23 three-layered interzone between the humerus and glenoid fossa of scapula was visible. In the 9th and 10th weeks distinct joint cavity was formed between humerus and glenoid labrum, and tendon of long head of Biceps brachii was attached to supraglenoid tuberosity and glenoid labrum. In the 11th week the joint cavity was formed between the midportion of humerus and glenoid fossa, and tendon of long head of Biceps brachii was more dense. In the 16th week the glenoid labrum was visible as fibrous cartilage, and joint cavity was more widened. In the 20th to 32nd week the shoulder joint was matured with the distinct joint cavity and glenoid labrum time after time.

Deveolopmental coax vara represents coax vara not present at birth but rather developing in early childhood, showing a progressive deterioration in the proximal femoral neck-shaft angle during growth. In order to determine the factors that could affect the results of corrective osteotomy, we evaluated the results of 15 developmental coax vara in 12 patients who had been treated with the femoral osteotomy at the Department of Pediatric Orthopedic Surgery, Seoul National University Children's Hospital, from February 1983 to March 1993. Of the 12 patients, there were 6 boys and 6 girls. Three patients had bilateral operations, 5 patients on the right, and the remaining 4 patients on the left. Average at the onset of symptoms was 4 years plus 5 months(range; from 1 year to 7 years plus 2 months), and average age at the tome of operation was 6 years plus 3 months(range; from 2 years plus 4 months to 10 years). We could obtain the following results: 1. Average post-operative loss of neck-shaft angle was 5% in the cases in which post-operative neck-shaft angle was converted more than 130 degrees, and was 8% in the cases in which post-operative neck-shaft angle was converted less than 130 degrees. 2. Loss of neck-shaft angle was higher during the first post-operative period, and was higher in cases in which the triangular osseous defect was persistent post-operatively. There was no correlation between the post-operative neck-shaft angle and disappearance of triangular osseous defect. 3. The femoral anteversion was converted 8.7 degrees to 27.2 postoperatively. 4. The premature arrest of the capital femoral physis was higher in cases in which the neck-shaft angle was less than 130 degrees postoperatively. 5. Leg length discrepancy, which was 2.1 cm preoperatively, did not change in cases in which the neck-shaft angle was more than 130 degrees postoperatively. However, it was converted to 3.3 cm in cases in which the neck-shaft angle was less than 130 postoperatively. 6. we could observe the femoral head deformity in 6 out of 7 cases in which the operation was performed after 7 years of age. We could draw the following conclusion based on our results: 1. We must correct the neck-shaft angle more than 130 degrees. 2. We could not equalize the leg length discrepancy by corrective osteotomy alone. 3. It may be reasonable to perform the corrective osteotomy before 7 years of age.

Esophageal hematoma is a rare form of esophageal injury. It may occur spontaneously, or in association with direct esophageal damage or a bleeding diathesis. Endoscopy and computed tomography are generally necessary for the establishment of a diagnosis. In this report, we present a case of esophageal hematoma that was discovered via a bedside transthoracic echocardiography. The echocardiography was conducted to evaluate an unexplained shock in a critically ill-patient. After conservative treatment, complete resolution of the esophageal hematoma was documented by a 7-day short-term follow-up of bedside transthoracic echocardiography. To the best of our knowledge, this is the first case report regarding transthoracic echocardiographic detection, differential diagnosis, and follow-up for esophageal hematoma.

PURPOSE: This study was designed to compare the clinical and radiologic outcome of the patients who underwent percutaneous vertebroplasty among the groups based on follow-up period and BMD. MATERIALS AND METHODS: A total of 99 patients (171 vertebral bodies) underwent percutaneous vertebroplasty from January 2001 to September 2003. The patients were divided into 3 groups by follow-up periods, and also divided into 2 groups by BMD. We investigated the difference of radiologic and clinical effects among the groups. Radiologic findings was assessed as vertebral height restoration rate and rate of reduction loss by measurement of the height of vertebral body. The clinical outcomes were graded into 5. The statistical analysis was done using Chi-squire test and Independent-samples T test. RESULTS: Among the groups divided by follow-up period, there was no statistically significant difference of clinical and radiologic results except the rate of reduction loss between group I and group III (p>0.05). Between the groups divided by BMD, there was no statistically significant difference of clinical and radiologic results. CONCLUSION: Percutaneous vertebroplasty with bone cement for the osteoporotic compression fracture is an efficient procedure and considered as technique producing pleasurable clinical and radiologic results regardless of follow up-period and BMD.

Hemolytic anemia is recognized as a rare complication of mitral valve replacement or repair. We report on a 44-year-old man with shortness of breath and hemolytic anemia, 23 years after mitral valve replacement (Hall-Kaster), and a 63-year-old woman diagnosed of hemolytic anemia, 4 years after mitral and tricuspid annuloplasty (Tailor ring, An-core ring). Routine 2-dimensional transthoracic echocardiography revealed paravalvular leakage around the prosthesis. Subsequent real-time 3-dimensional (3D)transesophageal echocardiography helped the perceptional appreciation of the leakage and the measuring of the regurgitant orifice area using the anatomically correct plane. Surgical findings of each case fit those of 3D volumetric images.

BACKGROUND: Despite aggressive treatment, the mortality rate of cardiogenic shock with acute myocardial infarction (AMI) is high. We performed extracorporeal membrane oxygenation (ECMO) prior to coronary reperfusion, and evaluated the early clinical results and risk factors. MATERIALS AND METHODS: From May 2006 to November 2009, we reviewed the medical records of 20 patients in cardiogenic shock with AMI (mean age 67.7+/-11.7 yrs, M : F 14 : 6). After initially performing ECMO using the CAPIOX emergency bypass system (EBS(R)Terumo, Tokyo, Japan), patients underwent coronary reperfusion (coronary artery bypass grafting, 13; percutaneous coronary intervention, 7). RESULTS: All patients were in a cardiogenic shock state, cardiopulmonary resuscitations (CPR) were performed for fourteen patients (mean CPR time 20.8+/-26.0 min). The mean time from vascular access to the initiation of ECMO was 17.2+/-9.4 min and mean support time was 3.8+/-4.0 days. Fourteen patients were able to be weaned from ECMO and ten patients were discharged (mean admission duration 50.1+/-31.6 days). Patients survived on average 476.6+/-374.6 days of follow-up. Longer CPR and support time, increased cardiac enzyme, lower ejection fraction, lower albumin, and major complications were the risk factors of mortality (p<0.05). CONCLUSION: The early application of ECMO prior to coronary reperfusion and control of risk factors allowed for good clinical results in cardiogenic shock with AMI.
