Free flap transplantation demands meticulous microsurgical technique to cover the exposed vital structures which is important to restore and maintain functions of the extremities. From July 1992 through December 2000, 99 patients were received reconstructive microsurgery in the upper and lower extremity at Department of Orthopedic Surgery, Chonbuk National University Hospital. The most common cause in the upper extremity was industrial accident, 8 cases of total 15 cases and in the lower extremity was traffic accident, 66 cases of total 84 cases. The most commonly involved site was thumb and finger, 8 cases of total 15 cases and in the lower extremity was leg, 65 cases of total 84 cases. In upper extremity, the wrap around free flap was carried out in 4 cases(4.0%), first dorsal metatarsal artery flap and lateral arm flap were 3 cases(3.0%) each in 15 cases and in lower extremity, latissimus dorsi myocutaneous flap were 23 cases(23.2%), gracilis 20cases(20.2%), and rectus abdominis muscle flap 18(18.2%) in 84 cases. Overall 89 cases(89.9%) of 99 cases were survived and maintained and revealed good cosmetic results.

New chords formation of mitral valve using expended-polytetrafluoroethylene sutures was performed in six patients with mitral regurgitation (MR) from April, 1994 to March, 1995. There were 3 men and 3 women whose mean age was 65 years, ranged from 55 to 75. A double-armed pledget suture was passed through the lateral portion of papillary muscle head and tied. Each arm of the suture was brought up to the free margin of the leaflet and passed through the area where the native chorda was attached. At leaflet surface, one more weaving was made. fter the lengths of the two arms were adjusted, the ends were tied. There were no operative deaths. Patients have been followed up from 2 to 13 months, mean 8. Echocardiographic sutudies were performed at 10 days after operation and revealed normal mitral valve function in all patients.

Synovial sarcoma us a rare malignant neoplasm of the soft tissue arising in the lower extremity, inguinal area, and upper arm. The majority occurs in patients between the age of 15 and 40 years. The histologic diagnosis is based on the classical biphasic type with the distinct epithelial and spindle cell components. We have recently encountered a case of metastatic synovial sarcoma of the lung diagnosed by fine needle aspiration cytology. A 34-year-old man was admitted because of a palpable mass on the antero-lateral side of the right tibia for 3 years. On admission, a well demarcated metastatic pulmonary nodule, measuring 5 cm in diameter, was also identified in the simple chest X-ray. Resection of the lower leg mass revealed typical histologic features of biphasic synovial sarcoma. Aspiration cytology of the pulmonary nodule revealed numerous clusters of spindle cells admixed with groups of epithelial cells. The epithelial cells had moderate-sized, round to oval shaped, and hyperchromatic nuclei. The cytoplasm was clear, but not distinctive. Interspersed tell elements were fibroblast-like spindle cells having elongated hyperchromatic nuclei.

Foreign body (FB) impaction in the maxillofacial area could be caused by knives, glass fragments, and vegetative materials. We present the rare case of a 62-year-old man with a large glass FB in the left cheek retained for over 40 years. He had traffic accident over 40 years ago and glass fragments impacted on his left cheek. Glass fragments were retained around the zygomatic arch with dimpled scar and unclear serous discharge, but other facial motor or sensory dysfunction was not observed. We confirmed three glass fragments with radiologic examination including plain radiograph and computed tomographic image. Under general anesthesia, impacted glass fragments were removed through the direct incision on the dimpled scar and the additional incision on the left lateral canthal area. Remnant FBs were not seen on an intraoperative C-arm radiograph. After 2 days of irrigation for inflammation control, the dimpled wound was sutured. The wound was healed without major complication and the original dimpled scar was much improved.

A cantilever beam with a mass and a spring at the end can be use to model a miniature flexible arm. It is necessary to know the natural frequencies and mode shapes to discuss its free vibration, especially when modal analysis is employed. A beam is clamped-free. In this paper we look at the lateral vibration of beams that have step changes in the properties of their cross sections. The frequency equation is derived by Bernoulli-Euler formulation and is sloved by the separation of variable. The parameters of the beam, 'mass and spring stiffness' are defined as nondimensionalized parameters for wide application of the results. According to the change of eigenvalues and mode shape are presented for this beam. The results presented are the eigenvalues and the natural frequencies for the first three modes of vibration. Results show that the parameters have a significant effect on the natural frequency.

Thoracic sympathetic ganglion block(TSGB) with alcohol is a traditional method for treating a variety of disease at pain clinics. But it is a difficult block to perform requiring both skill and experience. Therefore, we performed a thoracic endoscopic cauterization to evaluate the efficacy of this method. A patient suffering sever forearm and hand pain due to radius fracture of the right arm, one and half years earlier, was referred to several different orthopaedic department of various hospitals with continued aggravated symptoms. He was then admitted to our hospital's orthopaedic department. Our diagnosis, confirmed by thermography, revealed reflex sympathetic dystrophy. Patients was therefore referred to the pain clinic where treatment consisted of endoscopic thoracic sympathetic cauterization under general anesthesia. Patient was intubated with Robertashow 37 Fr. double lumen tube left sided. Left lateral and slight head up position was applied to make lesion side up. Incisions were made to penetrate trocas 5 mm diamether on 4 th intercostal space along mid axillary line and midclavicular line. Negative pressure suction on ipsilateral lung and CO2 insufflation under 10 mmHg was applied to reduce lung size. Cauterization on thoracic sympathetic chain at T3 level was done under endoscoic guide. 24 Fr. chest tube was inserted. Patient's symptoms cleared and he was satisfied with the results of this treatment.

Background: A transforaminal epidural steroid injection has been used for the treatment of radicular arm or leg pain, which has the advantage of ventral epidural spreading compared to either an interlaminar or caudal approach. However, several factors are known to affect the epidural spread pattern of contrast dye; therefore, the injected medication can not be delivered to the target site. The objective of our study was to observe any differences in the contrast flow patterns according to several factors. Methods: A total of 34 epidurographies in 29 patients, who underwent fluoroscopically guided transforaminal epidural steroid injections, were evaluated. After confirming the location of the needle tip within the anterior superior aspect of the neural foramen in the lateral view, and at the 6 o'clock position to the pedicle in the anteroposterior view, 2 ml of contrast dye was injected. The contrast flow patterns of ventral, ventral and dorsal, and dorsal epidural filling were analyzed, according to age, gender, magnetic resonance imaging finding and history of previous back surgery. Results: Ventral contrast flow occurred in 30 out of the 34 epidurographies (88%). Both ventral and dorsal contrast flow patterns were observed 13 out of 16 (81%) patients in the older age group. Also, both ventral and dorsal contrast flow patterns were observed in 16 out of 18 (88%) patients with spinal stenosis. Conclusions: Transforaminal epidural steroid injections, performed uner fluoroscopy, provide excellent nerve root filling and ventral epidural spreading. Patients with spinal stenosis or an old age have both ventral and dorsal epidural spreading patterns.

Background: Weakness of the abdominal and mid thoracic muscles the lead to thoracic kyphosis of stroke patients. The trunk muscles activity of stroke patients is significantly related to upper extremity. Objectives: To investigate the effect of seated exercise of thoracic and abdominal muscles on upper extremity function and trunk muscles activity in stroke patients. Design: One-group pretest-posttest design. Methods: A total of 27 stroke patients were recruited. All stroke patient were given seated abdominal exercise (posterior pelvic tilt exercises) and thoracic exercise (postural-correction exercise). All exercises were conducted for 30 minutes, three times a week for four weeks. The manual function test (MFT) and electromyography (EMG) were measured, and EMG electrodes were attached to thoracic paraspinal muscles and lower rectus abdominal muscles. EMG signal is expressed as %RVC (reference voluntary contraction). Results: Experimental group showed significant increases in abdominal muscles, paraspinal muscles activity and MFT total score, items of arm motion (forward elevation of the upper extremity, lateral elevation of the upper extremity, touch the occiput with the palm) in MFT after four weeks. Conclusion: These results suggest that, in stroke patients, seated exercise of thoracic and abdominal muscles contribute to improve trunk muscles activity and upper extremity function in stroke patients.

In order to study the shape and dimensions of heart, a procedure to reconstruct a three dimensional left ventricular geometry from two dimensional echocardiographic images was studied including the coordinate transformation, curve fitting and interpolation utilizing three dimensional position registration arm. Nonlinear material property of the left ventricular myocardium was obtained by finite element method performed on the reconstructed geometry and by optimization techniques which compared the computer predicted 3D deformation with the experimentally determined deformation. Elastic modulus ranged from 3.5g/$cm^2$ at early diastole to l53g/$cm^2$ at around end diastole showing slightly nonlinear relationship between the modulus and the pressure. Afterwards using the obtained nonlinear material propertry the stress distribution related with oxyzen consumption rate was analyzed. The maximum and minimum of ${\sigma}_1$ (max. principal stress) occurred at nodes on the second level intersection points of x-axis with endocardium and with epicardium, respectively. And the tendency of the interventricular septum to be flattened was observed from the compressive ${\sigma}_1$ on the anterior, posterior nodes of left ventricle and from the most significant change of dimension in $D_{RL}$ (septal-lateral dimension of right ventricle).
