A 43-year-old man experienced chest trauma due to a car accident. Compound sternal fractures with severe dislocation were seen on computed tomography of the chest. Using a SternaLock plating system with manual reduction, fixation of the sternal fracture was successfully performed. There were no complications related to the operation.

Intraosseous neurilemmoma is a rare benign neoplasm that accounts for less than 1% of all primary bone tumors. The most frequent site of involvement is the mandible. We report a case of intraosseous neurilemmoma of the sternum which was discovered incidentally.

Identification of an individual is the mainstay of forensic investigation. In the present study, criteria for sex determination were established using 111 adult Korean sternums (63 males and 48 females). They were analyzed using identification points (IPs) and limit points (LPs), as reported previously. Only three of the ten parameters measured-sternal body length, sternal length (i.e., manubrium+body), and sternal area-were useful for sex determination, with sternal length being the most useful. The IP of sternal length was 147 and 130 mm for males and females, respectively. Using this parameter, 53.9% of males and 37.5% of females could be sexed with 100% accuracy. The LP was 141 mm for both males and females; sex could be discriminated accurately using this parameter in 85.7% of males and 85.4% of females

Although the sternalis muscle has been well known to anatomists, it is quite unfamiliar to clinicians. During routine educational dissection, we came across a well-defined bilateral double sternalis muscle innervated by the intercostal nerve, respectively. The right sternalis muscle 1) became tendinous to insert into the sternum and 2) crossed midline and then intermingled with the left pectoralis major muscle, which could be classified into a double with single cross based on Snosek et al.'s criteria. The left sternalis muscle was composed of two bellies, which were combined at the midway, and became tendinous to insert into the contralateral manubrium, which could be classified into a bicipital diverging with double cross based on Snosek et al.'s criteria. The detailed knowledge on the sternalisis is important for clinicians as well as for anatomists, since the clinical importance of the sternalis muscle has been highlighted in recent years.

Background: In recent years, open heart surgery has developed rapidly in Vietnam. Sternal infection is a very serious complication for this surgery, it lead to increasing treatment costs and higher risk of mortality. Treatment of local infections is always a difficult technique in sternal wound infections after open heart operations. Objectives: (1) To improve and apply two techniques called \u201cdemi \ufffd?open + irrigation\ufffd? and \u201cclosed \ufffd?Redon drainage\ufffd? (2) To evaluate the effects of these techniques. Subjects and method: 20 cases of sternal infection (at Viet Duc hospital and some other hospitals in Ha Noi) were researched and described prospectively about diagnosis, techniques and treatment results. The subjects were divided in to 2 group based on the infection processing techniques. Results:Diagnosis had to reply on clinical signals (100%). Bacterial culture only provided 45% positive results, Pseudomonas aeruginosa (44.4%) were obtained more than Staphylococcus au\u2019reus (22.2%). Both techniques have their own reasonable creativeness and the standardized process, improving the limitations of ordinary technique, providing high treatment effectiveness \ufffd?85% have recovered after only one operation. Conclusion: For treatment of local infections, two techniques are both very efficient and suitable with the conditions in Vietnam, especially \u201cclosed \ufffd?Redon drainage\ufffd?technique.

PURPOSE: The purpose of this study was to assess optimal chest compression depth for infants and children compared with adults, when the simulated compression depth was delivered according to the current guidelines. METHODS: A total of 467 consecutive chest computed tomography scans (93 of infants, 110 of children, and 264 of adults) were reviewed. The anteroposterior (AP) diameter and compressible diameter (CD) for infants and children were measured at the inter-nipple level and at the middle of the lower half of the sternum for adults. Compression ratio (CR) to CD was calculated at simulated one-fourth, onethird, and one-half AP compressions in infants and children and simulated 5-cm, 6-cm compressions in adult. RESULTS: In adults, the CRs to CD at simulated 5-cm, 6-cm compression depth were 41.7±0.16%, 50.0±7.3%, respectively. In children and infants, the CRs to CD at onethird chest compression were, respectively, 55.1±2.4%, 51.8±2.4% and 82.7±3.7%, 77.7±3.6% at one-half chest compression. The CRs to CD of 4-cm compression depth in infants and 5-cm compression depth in children were 74.4±10.9%, 62.5±8.7%, respectively. The CRs to CD for children and infants were significantly higher compared with adults (p<0.001). The CR to CD of 4-cm compression depth in children was similar to that of 6-cm compression depth in adults (50.0±6.9% vs 50.0±7.3%, p=0.985). CONCLUSION: The current pediatric guideline for compression depth was too deep compared with adults. We suggest that one third of the AP chest diameter or approximately 4-cm in children and less than 4-cm in infants is more appropriate.

PURPOSE: We wanted to analyze the three dimensional images with using multidetector CT scanning of the sternum in children, and we wanted to compare the CT findings with the children's age. MATERIALS AND METHODS: We studied the three dimensional images of the sternum of 67 children (62 were boys and 5 were girls). The age of the children was 3-15 years old (mean age: 7.5). We evaluated the number of sternal bodies, the presence of the xiphoid process and the bifid shape of each sternal body. RESULTS: The number of sternal bodies was from three to five; 30 patients had 3 bodies, 25 patients had 4 bodies and 5 patients had 2. The number of sternal bodies was 3.4 in Group I, 3.5 in Group II and 3.9 in Group III. As the children's age increased, the number of sternal body was statistically increased. When the number of sternal bodies was three, the mean age of children was 5.4 year; when it was four or five, the mean age of children was 8.1 year. The children's age was increased as the number of sternal bodies increased. The mean age of the children with a xiphoid process was 7.0 years, and the mean age of children without a xiphoid process was 8.1. There was no statistical difference between the two groups with or without xiphoid process. Among the 67 children, 9 had the bifid shape in the 3rd portion of the sternal body, 5 had the bifid shape in 4th portion, 2 had the bifid shape in 2nd portion and 1 had the bifid shape in 5th portion. CONCLUSION: The number of sternal bodies was mostly three or four. The number of sternal bodies was related to the children's age. There is no relationship between children's age and the presence of the xiphoid process. The bifid shapes are mostly shown in the 3rd and 4th portion of the sternal body.

External compression of the right ventricle (RV) due to a depressed sternum in patients with pectus excavatum is uncommon. Moreover, mid-RV obstruction-induced cachexia rarely occurs in patients with pectus excavatum. We report a case of cardiac cachexia caused by significant RV compression in a patient with pectus excavatum.
