Ten patients with a thoracolumbar spine fractures were treated with Kaneda internal fixation device through anterolateral approach during last 1 year. In all cases, spinal decompression, internal instrument fixation and hone fusion with rib were performed. No patient showed neurological deterioration after surgery and 6(60%) patients improved postoperatively with entering the next Frankel subgroup. Follwo-up patient evaluation showed the correction of the fracture deformity with good bony fusion, but 3 patient arc remained back pain. According to above results we concluded that anterolateral internal fixation combined with hone fusion using rib was good mechanical stability and decompression of protruding ventral bone fragments above conus medullaris level.

Diabetes is marked by high glucose levels and is associated with decreased bone mass and increased fracture rates. To determine if [6]-gingerol could influence osteoblast dysfunction induced by 2-deoxy-D-ribose (dRib), osteoblastic MC3T3-E1 cells was treated with dRib and [6]-gingerol and markers of osteoblast function and oxidized protein were examined. [6]-Gingerol ($10^{-7}\;M$) significantly increased the growth of MC3T3-E1 cells in the presence of 30 mM dRib (p<0.05). [6]-Gingerol ($10^{-7}\;M$) caused a significant elevation of alkaline phosphatase (ALP) activity, collagen content, and osteocalcin secretion in the cells. We then examined the effect of [6]-gingerol on the production of osteoprotegerin and protein carbonyl in osteoblasts. Treatment with [6]-gingerol ($10^{-9}$ and $10^{-7}\;M$) increased osteoprotegerin secretion in osteoblastic cells. Moreover, [6]-gingerol ($10^{-9}$ and $10^{-7}\;M$) decreased protein carbonyl contents of osteoblastic MC3T3-E1 cells in the presence of 30 mM dRib. Taken together, these results demonstrate that [6]-gingerol inhibits dRib-induced damage and may be useful in the treatment of diabetes related bone diseases.

Traumatic aortic injury is well recognized as a primary cause of instantaneous death in victims of thoracic blunt trauma presenting with an aortic rupture or dissection, particularly after a deceleration injury. However, a direct aortic injury caused by a fractured rib segment after blunt thoracic trauma is extremely rare. We report the case of a 43-year-old male patient who experienced an aortic injury caused by the sharp edge of a fractured rib after multiple rib fractures due to blunt thoracic trauma.

Purpose: This study was conducted to analyze chest-trauma patients and the old-aged patients with a traumatic hemopneumothorax. Methods: We reviewed the medical records of 101 chest-trauma patients admitted to the department of cardiovascular and thoracic surgery from June 1999 to November 2008. We evaluated the general characteristics of the chest-trauma patient, especially those of old-aged patients with a traumatic hemopneumothorax. Results: Rib fracture was observed in 99 of the cases, the location distribution was right: left =261: 255, with right being dominant. Rib fractures commonly involved the 4th and the 7th rib. The average number of rib fractures was 5.1, and the average number of rib fractures in the old-aged patients was significantly higher than that in the non-old-aged patients (p=0.04). There were 17 cases of a hemopnuemothorax in old-aged patients, 52 cases in non-old-aged patients. The blood loss through the chest tube for old-aged patients was significantly more than that for the non-old-aged patients, and the initial hemoglobin level was lower in the old-aged patients. Conclusion: Elderly trauma patients are more likely to die after trauma than other age groups. Even with relatively stable vital signs, invasive hemodynamic monitoring and intensive treatment are recommended.

A clinical analysis was performed on 383 cases of chest injurjes experienced at Department of Thoracic Surgery, Seoul National University Hospital during 21 year period from 1957 to 1977. Of 383 patients of chest injuries, 209 cases were result from nonpenetrating injuries whereas 175 were from penetrating injuries, and there were 258 cases of hemothorax or/and pneumothorax, 162 of rib fracture, 33 of foreign body, 26 of clavicle fracture, 26 of lung contusion, 17 of diaphragmatic laceration, 14 of hemopericardium, 14 of flail chest and others. Stab wound was the most common in penetrating injuries and followed by gunshot and shell fragments. The majority of nonpenetrating chest injury patients were traffic accident victims. and fails accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 16 and 50 years, and 321 patients were male comparing to 62 of female. In blunt chest injuries the patients with five or more rib fractures had a 85 per cent incidence-of intrathoracic injury and 19 per cent had an intraabdominal organ damage, whereas those with four or less rib fractures had a 69 per cent and a 6 per cent incidence respectively. The principal associated injuries were cerebral contusion on 19 cases, renal contusion on 10, liver laceration on 7, peripheral vessel laceration on 5, spleen laceration on 3 and extremity fracture on 18 patients. The principles of therapy for early complications of chest trauma were rapid reexpansion of the lungs by thoracentesis [46 cases] and closed thoracotomy [125 cases] but open thoracotomy .had to be done on 90 cases [23-5%] because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic laceration and bronchial rupture. The over all mortality was 2.87 per cent [11 among 383 cases], 8 cases were from penetrating injuries and 3 from nonpenetrating injuries.

The moment resisting frame has been well-known as it had very excellent seismic performance, and it has been widely used and constructed in the design of a lot of buildings. However, the moment resisting frame system did not exert the seismic performance during the earthquake in Northridge and Kobe sufficiently, and it produced the crack or brittle fracture on the joint. this study was to ]m tests with the full-scale test subject as parameters of existence of H-beam web high tensile bolt shearing joint and reinforcement of H-flange rib. This researcher was to anticipate the decrease of number of high tensile bolts and the improvement of workability through the double shear joint by the experiment, and improve the seismic performance through the reinforcement of rib plate. In addition, this study was to prevent the brittle fracture by the stress concentration through the non scallop.

Clinical observations were performed on 17 cases of the traumatic sternal fracture, those were admitted and treated at the department of thoracic and cardiovascular surgery in Chosun University Hospital during the past 6 years 5months period from January 1983 to May 1989. Obtained results were as follows: 1. The frequency was about 4.8% of the nonpenetrating chest trauma. 2. The ratio of male to female was 16: 1 in male predominance and age distribution was from 24 to 62 years old. 3. The common cause were high decelerating injury [impact of the steering column] and falling down[more than 3 m in high]. 4. The most common fracture site was sternal body and next was sternomanubrial junction. 5. Associated intrathoracic organ injuries were cardiac contusion [6 cases], hemopneumothorax[1 Case], mediastinal bleeding[1 case], and thoracic cage and extrathoracic organ injuries were rib fracture, head injuries, thoracic spinal fracture, and long bone fracture. 6. Abnormal EGG findings were sinus bradycardia[1 case], bundle branch block [2 cases], and sinus tachycardia[3 cases]. 7. The operative reduction and fixation was necessary in only one case and the others were treated with conservative treatment.

Purpose: The use of surgical stabilization of rib fractures (SSRF) has steadily increased over the past decade. Recent literature suggests that a larger population may benefit from SSRF, and that the geriatric population-as the highest-risk population-may receive the greatest improvement from these interventions. We sought to determine the overall utilization of SSRF in the United States. Methods: The National Trauma Database was analyzed between 2016 and 2017. The inclusion criteria were all patients ≥65 years old with rib fractures. We further stratified these patients according to age (65-79 vs. ≥80 years old), the presence of coding for flail chest, three or more rib fractures, and intervention (surgical vs. nonoperative management). The main outcomes were surgical interventions, mortality, pneumonia, length of stay, intensive care unit length of stay, ventilator use, and tracheostomy. Results: Overall, 93,638 patients were identified. SSRF was performed in 992 patients. Patients who underwent SSRF had improved mortality in the 65 to 79 age group, regardless of the number of ribs fractured. We identified 92,637 patients in the age group of 65 to 79 years old who did not undergo SSRF. This represents an additional 20,000 patients annually who may benefit from SSRF. Conclusions: By conservative standards and the well-established Eastern Association for the Surgery of Trauma clinical practice guidelines, SSRF is underutilized. Our data suggest that SSRF may be very beneficial for the geriatric population, specifically those aged 65 to 79 years with any rib fractures. We hypothesize that roughly 20,000 additional cases will meet the inclusion criteria for SSRF each year. It is therefore imperative that we train acute care surgeons in this skill set.

Purpose: Clinical reports on treatment outcomes of sternal fractures are lacking. This study details the clinical features, treatment approaches, and outcomes related to traumatic sternal fractures over a 10-year period at a single institution. Methods: A retrospective cohort study was conducted of patients admitted to a regional trauma center between January 2012 and December 2021. Among 7,918 patients with chest injuries, 266 were diagnosed with traumatic sternal fractures. Patient data were collected, including demographics, injury mechanisms, severity, associated injuries, sternal fracture characteristics, hospital stay duration, mortality, respiratory complications, and surgical details. Surgical indications encompassed emergency cases involving intrathoracic injuries, unstable fractures, severe dislocations, flail chest, malunion, and persistent high-grade pain. Results: Of 266 patients with traumatic sternal fractures, 260 were included; 98 underwent surgical treatment for sternal fractures, while 162 were managed conservatively. Surgical indications ranged from intrathoracic organ or blood vessel injuries necessitating thoracotomy to unstable fractures with severe dislocations. Factors influencing surgical treatment included flail motion and rib fracture. The median length of intensive care unit stay was 5.4 days (interquartile range [IQR], 1.5-18.0 days) for the nonsurgery group and 8.6 days (IQR, 3.3-23.6 days) for the surgery group. The median length of hospital stay was 20.9 days (IQR, 9.3-48.3 days) for the nonsurgery group and 27.5 days (IQR, 17.0 to 58.0 days) for the surgery group. The between-group differences were not statistically significant. Surgical interventions were successful, with stable bone union and minimal complications. Flail motion in the presence of rib fracture was a crucial consideration for surgical intervention. Conclusions: Surgical treatment recommendations for sternal fractures vary based on flail chest presence, displacement degree, and rib fracture. Surgery is recommended for patients with offset-type sternal fractures with rib and segmental sternal fractures. Surgical intervention led to stable bone union and minimal complications.
