Objectives: This study was done to determine the prevalence of radiographic ankle osteoarthritis (OA) in Korean women with clinical primary ankle OA. Methods: This analysis involved 160 Korean women who visited our out patient clinic due to ankle joint pain. Ankle AP and lateral weight-bearing radiographs were evaluated retrospectively to check whether they have radiographic OA or not. Radiographs were read for features of ankle OA using School classification. Demographic factors and radiographic findings in both radiographic ankle OA group and non-radiographic ankle OA group were analyzed by the student t-test, the chi square test and the Pearson's analysis. A p value <0.05 was considered significant. Results: The prevalence of radiographic ankle OA in Korean women is 18.2 % in patient between 18 and 39 years and is 55.6 % in patient over 40. There was significant difference between two groups with age (P<0.001) and relatively strong correlation between radiographic OA and age (r=0.474, P<0.001). Conclusion: These results show that the prevalence of Korean women with radiographic changes of ankle OA was 45 % and there was relatively strong correlation between age and radiographic ankle OA.

Purpose: To investigate the relationship between classification based on simple radiographic findings and arthroscopic findings of the cartilage lesions in medial degenerative arthritis of the ankle joint. Materials and Methods: We studied 41 ankles of 36 patients with asymmetrical narrowing of the medial joint space. Degenerative arthritis following fracture and those with generalized arthritic disease were excluded, but those with a history of ankle sprain were included. Standing radiographs of all patients were graded according to the Takakura classification and the Kellgren-Lawrence (K/L) classification. Arthroscopic findings were classified according to the depth, width, and anteroposterior dimension of articular cartilage damage. Results: According to the Takakura classification, 29 ankles were classified as stage II, 7 cases as stage IIIA and 2 cases as stage IIIB. According to our classification of arthroscopic findings of 29 ankles in stage II, 1 ankle was graded as Grade I, 3 ankles as grade II, 10 ankles as grade III, and 15 ankles as grade IV. Spearman correlation coefficient between Takakura classification and arthroscopic classification was 0.342 (P=0.028), and coefficient between K/L classification and arthroscopic classification was 0.480 (P=0.001). Conclusion: Degenerative changes of the articular cartilage are more advanced than radiographic findings in many patients with ankle degenerative arthritis with asymmetrical narrowing of medial joint space. Therefore, we conclude that more aggressive effort should be made for correct diagnosis and treatment of degenerative arthritis.

The purpose of this report Is to discribe the radiological findings of traumatic elbow luxation and subluxation of carpal joint which were caused by being hit by a wild animal and forced hyperextension of carpus in two hunting dogs. In case 1, carniocaudal and mediolateral radiographic examination of the elbow joint revealed that the radius that the radius and ulna were completely luxated laterally. The lateral projection showed the humeral condyles overlying the radial head with an absent joint space, but displacement is apparent on the craniocaudal projection. Incidence of collateral ligament rupture in conjunction with elbow luxation was not recognized on physical examination of the limb after closed reduction. Radiographic examination of the elbow made 5 months after closed reduction revealed only mild degenerative joint disease. Radiographic examination of the carpus in case 2 demonstrated palmar subluxation of most carpal joints including antebrachiocarpal, mediocarpal carpometacarpal joints, and some intercarpal joints, and avulsion fracture of the palmar surface of the accessory carpal bone. However, the mediocarpal and carpometacarpal joints were most severely affected by tensile forces of hyperextension, and it was concluded that the ligaments of the middle ca,pal joints and carpometacarpal joints as well as the palmar fibrocartilage were ruptured based on clinical and radiographic findings. In elbow luxation and subluxation of carpal Joints of the dog, differentiation of the joint or joints involved, and ligamentous structures damaged is important in determining whether surgery Is necessary and which procedure is most appropriate. And the radiographic findings of these conditions would be of help to practitioners.

5 years Poodle was referred to the Veterinary Teaching Hospital, Chonnam National University in January 1997, with progressive swelling on the rear xiphoid process after cesarean section last year in local-vet clinic. Physical, radiographic, ultrasonographic and intraoperative findings that were obtained from this case were as follow; Physical findings were known as no pain, no fever in the hernia] sal at palpation. Radiographic findings revealed the decreased density of swelling contents more than peritoneum and did not identify the abdominal wall defect line. Ultrasonographic findings showed abdominal wall defect line of 3mm and intra-abdominal originated fat contents with mixed echo(hypoechoic). During the operation, falciform ligament into the hernial sac was observed and not excised, manipulated back into the cavity. The dog was given an herniorraphy with no recurrence and infection.

The purpose of this study was to evaluate the initial and postoperative radiographic features of the endodontic treated teeth. The author examined the radiographs which comprise 114 teeth with 155 canals of 64 persons. The following factors were considered; Age, sex, tooth location, number of root canals, postoperative periods, initial diagnosis, and radiographic findings, postoperative radiographic findings. The apical levels of the root fillings were 76.8% to apex, 19.0% underfilling, 3.9% overfilling. The following results were obtained. 1. Of the 93 teeth which revealed initial periapical rarefaction, 66 teeth (71.0%) had showed complete bone healing, 19 teeth (20.4%) decreased rarefaction, 6 teeth (6.5%) no change, 2 teeth (2.2%) increased rarefaction after 20.0 months mean healing time. 2. 21 teeth which had no initial periapical rarefaction showed no occurrence of new periapical rarefaction. 3. Of the 66 teeth completely healed, 53 teeth (80.3%) had showed reappearance of lamina dura, 64 teeth (97.0%) reappearance of periodontal ligament space after 23.4 months mean healing time.

Purpose: To evaluate a usefulness of the simple radiograph in the patients with chronic shoulder pain 50 years and older. Material and method: 1152 patients with chronic shoulder pain and 100 asymptomatic individuals were involved in this study. All patients were 50 years and older. We excluded patients who had a history of fracture or dislocation. Radiographic interpretation was performed on a shoulder AP view, an axillary view and a supraspinatus outlet view. For statistical analysis, a chi-square test was performed. A p value of <0.05 was considered statistically significant. Results: Abnormal radiologic findings were identified in 369(32%) out of 1152 patients with a shoulder pain: greater tuberosity sclerosis, acromial sclerosis, subacromial osteophytes are common abnormal radiologic findings. A rotator cuff tear or impingement syndrome was identified on a final diagnosis in 61(85.2%) out of the 76 patients with radiologic abnormalities in both greater tuberosity and acromion (p<0.05). Abnormal radiologic findings were identified in 18% of the asymptomatic individuals. Conclusion: Simple radiographic analysis is an important primary diagnostic tool in patients (50 years and old) with chronic shoulder pain.

A 2.5 kg, three-month-old. intact male Shih-tzu was referred to the Veterinary Teaching Hospital of Kyungpook National University to examine the postoperative inflammation and suspected diaphragmatic defect which had been found during the surgical correction of umbilical hernia by the referral veterinarian. An umbilical hernia had been surgically repaired one month earlier at the time. Radiographic findings were enlarged cardiac silhouette containing soft tissue and gas densities and overlapping of cardiac and diaphragmatic borders. Ultrasonographic findings revealed the discontinuity of the diaphragm and the partial herniation of the liver into the pericardial sac. According to these findings, it was diagnosed as congenital peritoneopericardial diaphragmatic hernia(PPDH). Because the dog showed no serious clinical signs of PPDH and the owner didn't want a surgery to correct it, the dog was discharged the day of the examination after treatment of the inflammatory surgical site. On the follow-up after three months, the dog showed no distinct clinical signs of PPDH and was in good physical condition.

Early CT findings of transient radiographic progression (TRP) during treatment of active pulmonary tuberculosis including subpleural, interlobular or intralobular septal thickening and micronodules are shown in the present case. Late CT findings of TRP are subpleural, enhancing nodular infiltration with internal low attenuation. These CT features accompanied by a lack of clinical worsening in young patients taking antituberculous medication due to pulmonary tuberculosis can help to differentiate TRP from other disease entities.

A 11 month-old Shihtzu was referred to the Veterinary Medical Teaching Hospital, Seoul National University. Clinical signs of this patient were lameness, shortening limb, angular deformity, rotation of foot, subluxaion of elbow joint and restricted range of movement of left forelimb. For the evaluation of the abnormalities of left forelimb, radiographic examination was carried out. Radiographic findings were characteristics of premature closure of distal ulna such as closure of distal ulna growth plate and cranial bowing of radius. With radiographic signs and physical examination, it was diagnosed as premature closure of growth plate of the left forelimb. After osteotomy of the radius and ostectomy of the ulna, radiographic evaluation of limb about angulation of elbow joint was performed every 2-3 weeks for 3 months. In case of premature closure of distal growth plate of ulna, radiography was very useful for diagnositic method of premature closure of distal ulna and monitoring of healing process.
