  • Objectives: The purpose of this study is to report the improvement of multiple rib fracture after korean medical treatment; adhesive treatment and herb-medicine treatment. Methods: A patient with multiple rib fracture was treated with Daewhangchija-paste(大黃梔子膏) adhesive and herb-medicine treatment. Verbal numeric rating scale, medical examination by interview and rib series x-ray were used to assess progress of treatment. And we took pictures of left flank after attaching Daewhangchija-paste to observe the changes of the skin colors. Results: Rib series x-ray taken after 2 months of treatment revealed hard callus which added stability against external force on rib cage. After taking off Daewhangchija-paste, left plank skin turned into blue, green and yellow. And the pain level(VNRS) of left plank decreased from 10 to 0.5 for 4 months. Conclusions: Pain reduction on trauma site and improvement of general health condition were observed during combination treatment of Daewhangchija-paste adhesive and herb-medicine.

  • This paper describes a finite element analysis (FEA) of the body frame of a subsea robot, Crabster200 (CR200). CR200 has six legs for mobility instead of screw type propellers, which distinguishes it from previous underwater robots such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs). Another distinguishing characteristic is the body frame, which is made of carbon fiber reinforced plastic (CFRP). This body frame is designed as a rib cage structure in order to disperse the applied external loads and reduce the weight. The frame should be strong enough to support many devices for exploration and operation underwater. For a reasonable FEA, we carried out specimen tests. Using the obtained material properties, we performed a modal analysis and FEA for CR200 with a ready posture. Finally, this paper presents the FEA results for the CFRP body frame and the compares the characteristics of CFRP with conventional material, aluminum.

  • Acute Complications of Remodelling Plasty of Costochondral Rib Cage For Pectus excavatum Recently, Remodelling Plasty of Costochondral Rib Cage has been introduced as an minimally invasive procedure and expanded its application for pectus excavatum. Outcomes and acute complications were reviewed Material and Method: A retrospective survey of 55 patients who underwent Remodelling Plasty of Costochondral Rib Cage from September, 1999 to February, 2002 was conducted to review complications, postoperative treatments, and outcomes. Result: Age ranged from 1 to 27 years(mean 11.4 $\pm$ 7.1). 35(64%) were less than 15-year old and 20(36%) were more than 15-year old. There were 44(80%) Male patients and 11(20%) female patients. Length of hospital stay was 7.8 $\pm$ 2.1 days for less than 15-Y-old group, 10.6 $\pm$ 6.2 days for more than 15-Y-old group(p = 0.042) One substernal bar was inserted in 52 patients and two substernal bars were inserted in 3 patients. As for stabilizer, one lateral side was fastened in 15 patients and both lateral sides were fastened in 6 patients. In the less than 15-Y-old group, 4 patients needed stabilizer, whereas in the more than 15-Y-old group, 18 patients needed stebilizer(s)(p = 0.000). Including all kinds of complications, 28(51 %)patients had postoperative complications. Of them, only 7 patients were treated for complications(C-tube insertion was done in 7 patients and reoperation for bar refixation or removal was done in 3 patients of them). Conclusion: Most complications after Remodelling Plasty of Costochondral Rib Cage For Pectus Excavatum were trivial without treatment although C-tube drainage was needed in some patients. However bar displacement such as rotation and lateral sliding should be corrected as soon as detected in order not to remove the bar(the worst situation).

  • Background: Chronic obstructive pulmonary disease (COPD) may cause changes in the shape of the thoracic cage by increasing lung volume and hyperinflation. This study investigated changes in thoracic cage dimensions and related factors in patients with COPD. Methods: We enrolled 85 patients with COPD (76 males, 9 females; mean age, $70.6{\pm}7.1years$) and 30 normal controls. Thoracic cage dimensions were measured using chest computed tomography at levels 3, 6, and 9 of the thoracic spine. We measured the maximal transverse diameter, mid-sagittal anteroposterior (AP) diameter, and maximal AP diameter of the right and left hemithorax. Results: The average AP diameter was significantly greater in patients with COPD compared with normal controls ($13.1{\pm}2.8cm$ vs. $12.2{\pm}1.13cm$, respectively; p=0.001). The ratio of AP/transverse diameter of the thoracic cage was also significantly greater in patients with COPD compared with normal controls ($0.66{\pm}0.061$ vs. $0.61{\pm}0.86$; p=0.002). In COPD patients, the AP diameter of the thoracic cage was positively correlated with body mass index (BMI) and 6-minute walk test distance (r=0.395, p<0.001 and r=0.238, p=0.028) and negatively correlated with increasing age (r=-0.231, p=0.034). Multiple regression analysis revealed independent correlation only between BMI and increased ratio of AP/transverse diameter of the thoracic cage (p<0.001). Conclusion: Patients with COPD exhibited an increased AP diameter of the thoracic cage compared with normal controls. BMI was associated with increased AP diameter in these patients.

  • Authors have reviewed the records of seven patients of multiple rib fractures with severe flail chest who were admitted to Hanyang University Hospital during the 3 years period from 1972 through 1975. Of the seven patients studied, automobile accidents led to the injuries in 4 cases, two patients were injured in fall from a tree and on the ox-heading. All who had a blunt trauma without any open wound on the chest. The numbers of the fractured ribs accounted for 6 to 9 of the ribs including double fractures from 3 to 5 ribs. The left side fractures occurred in the 6 patients and in the right only one patient. Thus the flail segment was more often located in the left antero-lateral position than in the right lateral position [the ratio was 6:1].. All cases had associated injuries. The injuries and multiple fractures were the most common associated injuries occurring in four and five of the patients respectively. The patients were classified as having associated head injuries when they were admitted in comatose or semicomatose state. When a major degree of instability of the thoracic cage exists, adequate respiratory change is not possible. For this reason the tracheostomy was performed in five patients in an acutely injured patient with flail chest only after an endotracheal tube has been inserted or after an endotracheal suction. All patients had secondary complications in the pleural cavity, such as hemothorax or hemopneumothorax with or without intrapulmonary hemorrhage and subcutaneous emphysema. Therefore, closed thoracostomy was performed in five patients in the emergency room. The thoracotomy was required in four patients: immediate operation without closed thoracostomy was performed in two patients and the thoracotomy was indicated in two patients after closed thoracostomy, because of increasing intrathoracic hemorrhage. As to the fixation of the flail segments, authors employed two techniques; one was towel clip traction of the flail segments and the other was intramedullary insertion of Kirschner`s wire in to the double fractured rib fragments for the fixation of the flail segments [Kirschner`s wire fixation]. Because` of an different results in the course of treatment between two techniques, data from patients with towel clip traction was compared with those from patients with thoracotomy and Kirschner`s wire fixation of the flail segments. Of the three patients with towel clip traction, two patients required bronchoscopic toilet due to lung atelectasis which developed because of inadequate motion of thoracic cage and poor expectoration. This was in contrast to the four patients with thoracotomy and Kirschner`s wire fixation, who didn`t these complication because of adequate motion of the thoracic cage and subsequent good expectoration.

  • 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.

  • Cleidocranial dysplasia is a rare, autosomal dominant congenital disorder. A 12-year old female visited with chief complaint of unerupted permanent teeth. Also her father showed severe class III malocclusion. The extraoral radiography and computed tomography showed delayed closure of the cranial sutures and underdevelopment of maxilla, maxillary sinuses, and frontal sinus. Both clavicles were underdeveloped and thoracic rib cage was bell­shaped. Both zygomatic process appeared as hypoplastic feature. There were many unerupted permanent and supernumerary teeth in the maxilla and mandible. We examined location and number of the unerupted teeth using 3D CT. Finally we could conclude this case was cleidocranial dysplasia based on the clinico-radiologic findings.

  • We present a case of chondroblastoma in the thoracic vertebra. A 40-year-old patient with upper back pain and lower extremity weakness was admitted to our clinic. On neurological examination, the patient exhibited lower extremity spastic paraparesis. Magnetic resonance imaging revealed a mass infiltrating the 7th thoracic vertebra and its adjacent structures with concomitant compression of the epidural space. After right upper lung tuberculoma was resected through the transthoracic approach, T7 total corpectomy was done with anterior stabilization using a MESH cage and T7 rib bone graft. Two weeks after the first operation, remained part of vertebra was removed and posterior stabilization was performed using a pedicle screw fixation and cross linkage bar with the assistance of the navigation system. The final pathologic diagnosis of the vertebral lesion was benign chondroblastoma.

  • Desmoid tumor is found most often in the anterior abdominal wall of parous women. Although it may originate in virtually any musculotendinous structure, those of the chest wall are rare. We experienced a case of large dumb bell shaped desmoid tumor originated in intercostal muscle and invaded anterior chest wall, pericardium, pleura and the lung. The patient was healthy in appearance except a painful swelling on the anterior chest wall. Roentgenographic studies demonstrated a huge homogenous mass in the right anterior chest cavity. He was treated with resection of the tumor including .anterior chest wall, a portion of the pericardium, middle lobe, and part of upper & lower lobes of the right lung because of tumor invasion. The tumor composed with two parts, one [$5{\times}4{\times}3$cm in size] is over the rib cage and another [$10{\times}15{\times}10$cm in size] is in the right chest cavity. Postoperative course was uneventful and there was no evidence of recurrence until last visit, 5 months after surgery.

  • A FE model is to develop a personalized biomechanical model of the scoliotic spine that will allow the design of clinical test providing optimal estimation of the post-operation results. A flexible multi-body model of the spine including rib cage, clavicle, and scapular was developed to simulate several mobility simulations. Vertebrae, clavicle and scapular were represented using rigid bodies and ribs and sternum were modeled as flexible bodies. Kinematical Joints and spring elements were used to represent the intervertebral disc and ligaments respectively. Postero-anterior and lateral radiographics of a scoliotic spine were used to represent a 3D reconstruction. CT data for same patient were also used to verify vertebrae rotation driven from postero-anterior and lateral radiographic images. Simulated results showed good reducibility almost uniformly distributed along the spinal segments. It was also found that boundary and loading conditions, required to mimic the operation procedures, were proven to be very sensitive parameters to its results rather than its mechanical properties
