Background: The literature on variations of rib is limited. Very little has been written in the radiological journal of this country on the subject. It seemed of interest to investigate the nature and incidence of congenital variations in a series of routine chest roentgenograms. The topic of rib variations has not been covered extensively in the radiological journals in Korea. This has presented an opportunity to investigate the nature, type, shape and incidences of congenital rib variations in normal Korean adults from a series of routine roentgenograms. Methods: Chest radiographs of 5,000 adults, who visited our hospital for a routine check-up or for employment physical examinations from January 1996 to September 1998, were consecutively reviewed. The sex distribution consisted of 2,827 male males and 2,173 female females(ratio of 1.3:1) with the age range aged between 19 and 65 years(mean age: 34.6 years) were included. The chest PAs were analyzed for the presence, type, location, and shape of the rib variations. From this data the incidence of each type of variations was calculated. Results: Seventy-six of the 5,000 adults(1.52%), 63 male(2.23%) and 13 female(0.6%), showed 88 cases of rib variation(Table 1). The most common variation was the bifid rib(n=35), followed by hypoplasia of the rib(n=22), flaring of the rib(n=18), bridging of the ribs(n=7), cervical ribs(n=3), and fusion of between ribs(n=3)(Table 2). The bifid rib(Table 1) was found most frequent in the right fourth rib(12/35, 34.3%), followed by the left fifth rib(6/35, 17.1%) and right third rib(6/35, 17.1%). Hypoplasia of the rib was common in first rib(20/22, 90.9%). Flaring of the rib was common at fourth rib(8/18, 44.4%, right and left combined), and bridging between ribs was common between first and second rib(3/7, 42.9%). Conclusion : The percentage of incidence of rib variations in adults was 1.52%. Bifid rib was the most common variation, followed by hypoplasia, flaring, bridging, cervical rib, and fusion of ribs, in decreasing order.

Isolated stress fracture of the first rib is rare, and repeated muscular pulling and fatigue of bone is thought to be responsible for this fracture. The diagnosis can be made by taking a thorough history and performing chest roentgenography, computed tomography or magnetic resonance imaging. Conservative treatment generally cures this condition. We report here on a case of exercise-induced isolated stress fracture of the first rib in a non-athlete college student and we review the related articles.

Background: Thoracoscopic R3 (above the third rib)sympathicotomy has been performed as an effective method in treating palmar hyperhidrosis because it is effective in eliminating the symptoms of hyperhidrosis and has lower degree of compensatory hyperhidrosis than that of sympathectomy. Most of the results published were based on the short-term follow up. So we evaluated the intermediate term follow up results of the R3 sympathicotomy. Material and Method: From April 1999 to August 2001, ninety-four patients with palmar hyperhidrosis had been treated by R3 sympathicotomy at the Inha University Hospital. Follow-up study was completed for 76 patients (male 38, female 38) and average follow-up period were 25$\pm$9.1 (15∼50) months. The sympathetic trunk passing above the upper border of third rib was divided by electric cautery. The patient's satisfaction after surgery was estimated using the analogue scale from score 0 to 100 (100 means perfect satisfaction). Result. The scale of patient's satisfaction immediately after operation was 92.36$\pm$9.93. After 15 months, the scale of satisfaction was decreased to average 71.80$\pm$20.24 and it is statiscally significant. The cause of dissatisfaction were compensatory hyper-hidrosis and recurrence of symptom. The degree of sweating immediately after operation was mean 0 and after 15 months it increased to mean 1.5. The degree of the compensatory hyperhidrosis immediately after operation was mean 1 and it increased to mean 5 after 15 months. Conclusion: R3 sympathicotomy has excellent therapeutic results immediately after operation but therapeutic effectiveness is becoming to decrease 15 months after operation. The common causes of dissatisfaction are compensatory hyperhidrosis and recurrence of hyperhidrosis.

A 17-year-old-boy with a bilateral incomplete cervical rib, upon abduction of his left arm at 45 degrees, had immediately begun to show symptoms of severe tingling, claudication, pallor, and weakness of his left upper extremity. These symptoms were aggravated at 90 degrees, leaving him debilitated from his work in the printing office. Transfemoral positional subclavian arteriography revealed total occlusion of the subclavian artery immediately distal to a cervical rib during 90 degrees abduction. Resection of the anterior scalene and medial aspect of the middle scalene muscles, cervical and first ribs, and arteriolysis were performed via a combined supraclavicular and infraclavi cular approach. He has returned to work as a printer with marked relief of symptoms and has remained asymptomatic over follow-up periods of 10 months.

Aneurysmal bone cyst of the rib is a rare benign tumor which resembles the giant cell tumor or fibrous dysplasia of the bone. It rarely develops in the rib although it affects the metaphysis of the long bone and facial bone. We have treated a 14 year old male patient who had the aneurysmal bone cyst in the legt 4th. rib. Wide surgical resection of the affected rib was carried out with good clinical result. He is well 16 months after the resection.

Synovial sarcoma is an uncommon malignant mesenchymal tumor that occurs in the vicinity of the joints, bursae, and tendon sheaths. Typically the lesions are located in the extremities, especially in the lower extremities. They also occur in the abdominal and thoracic walls, but rarely in the head and neck. We experienced a case of synovial sarcoma of the rib in 17-year -old woman. We performed on bloc chest wall resection including the right second rib tumor, fi st and third ribs. The postoperative course was uneventful. She received chemotherapy because of a relapse of the tumor in sternum and both lung during follow-up.

Osteochondromadevelop most commonly at distal femur, proximal humerus and proximal tibia, but the rib osteochondroma was reported less commonly. In this report, scapular snapping syndrome complicated by adventitious bursa and soft tissue pseudotumor surrounding the osteochondroma of the $6^{th}$ rib body was treated successfully by surgical excision of them. We report this rare case with reviewing the relevant literature.

Patients with fractured ribs necessarily suffer from severe chest ain, which prevents coughing, deep breathing and bronchial toilette, cause atelectasis and pulmonary shunting. Relief of chest pain is benecial to patients, providing consort and facilitating physiotherapy and effective expectoration. We compared the efficacy of pain relief be!ween continuous epidural analgesia and conventional intramlrscular analgesia in 20 patients with fractured ribs. Among 20 patients, epidural analgesia was done or 10 patients(experimental group) and the remainder ten received intramuscular analgesia(control group). The pain and ROM(range of motion) scores, vital sign, PaO2, forced vital capacity(FVC) and forced expiratory volume for 1 second(FEVI) were checked on immediate admission and 12, 24 hours, third, fifth, and seventh day after starting of continuous epidural block. The pain and ROM scores were decreased and the PaO2, FRC and FEVI were significantly increased in experimental group. The side effects of epidural analgesia were mild and reversible. With th se result, we can suggest that epidural analgesia is more effective for pain relief and restoration of pulmonary mechanics in patients with fractured ribs.

The method of insertion of T-type cannula into the proximal duodenum of cattle was established for the feed digestibility test. Five cattle were anesthetized with rumpun and 2% lidocaine. The incision(15 ~ 20 cm) through the abdominal wall exposing the peritoneal cavity was made. The identified duodenum was extracted through the abdominal incision. The cannula was inserted into the incised duodenal wall. Cannula barrel was extracted between the 10th and 11th rib. All of operated cattle were healthy and cannula remained completely functional until 20 months after a proximal duodenal cannulation.
