We have compared the computed tomographic(C. T.) findings with those of conventional roentgenogram(simple AP and lateral radiograms) in 18 cases of osteochondritis dissecans of the capitellum humeri available for review. Among the 18 cases, 2 cases of them had a lesion of osteochondritis dissecans on C. T. which, however, had not been found on conventional rentgenograms. Fro the 5 cases, which had not clearly found on conventional rentgenograms, 2 loose body on conventional view, 3 cases had different numbers and locations of loose body on C. T. films. On the bases of our findings, we recommend that C. T. is necessary in early detection and the determination of anatomical location and status of osteochondritis dissecans of capitellum.

While the microbiology of cellulitis in the pediatric population and systemic diseases(DM, Cirrhosis, etc) is well known,the causative bacteria and clinical aspect of cellulitis in young adults are less descrihed. this study was undertaken to identify the causative organisms and clinical aspect of adult cellulits. We analysed 121 medical records of 115 young adult patients with cellulitis who had been admitted at the department of orthopaedic surgery, National Police hospital from Jan. 1994. to Dec. 1996. The results were as follows. 1. The age of patient was between 21 yrs and 25 yrs, and the sex of all patients was male. 2. The lower leg and foot were the most frequently involved site of cellulitis as 92 cases(74.2%). 3. The potals were suspected in 65 cases(56.5%),of them, traumas were detected in 43 cases(66.1%), non-traumatic skin lesions in 23 cases(33.9%). 4. In most cases, initial systemic symptoms (fever, chill, headache, etc.) and local symptoms (local heating, tenderness, etc.) were found. 5. The laboratory findings revealed leukocytosis in 19%, elevated ESR in 94%, positive CRP in 80%. 6. Microorganism were detected in 16 of 38 pus cultures. Gram positive microorganisms were detected in 15 of 16 cases culture positive. 7. 6.7% of patients with cellulitis experienced recurrence in same lesions. In conclusion, the retrospective analysis of 115 young adult patients with cellulitis showed that primary cause of young adult cellulit was circulatory disturbance and lymphatic obstruction of the lower extremities most often involved by trauma. therefore, supportive treatments such as rest,elevation,ice packs are considered prior to antibiotic treatment.antibiotic treatment aimed at gram-positive cocci appears to be sufficient.

Tumor and tumor-like lesion of the patella are extremely rare. The following have been reported: giant cell tumor; osteoblastoma; osteoid osteoma; chondroblastoma; solitary osteochon droma; chondroma; ganglion; simple bone cyst; aneurysmal bone cyst; hyperparathyrodism (brown tumor); malignant lymphoma; haemangioendothelioma; haemangima; primary osteosarcoma; plasmocytoma and metastases. Chodroblastoma in patella were very rare and first repoted by Jerone Cohren in 1963. On review of our literatures, we could not find reported case in Korea. The purpose of this paper is to present an unusual case of chondroblastoma of the patella.

PURPOSE: To compare the results of posterior cruciate ligament reconstruction by open and arthroscopic method. MATERIALS AND METHODS: From 1995 to 1997, 18 reconstructions of posterior cruciate ligament were performed. Group 1 (open method) was composed of 9 cases and group 2 (arthroscopic method) was consisted of 9 cases. After 21-month follow-up, The two groups were compared by clinical and radiologic methods. RESULTS: Clinically, Lysholm knee score was 80 points in group 1 and 83 points in group 2 after operation. Post operative results by Hughston's criteria were good in 5, fair in 2 and poor in 2 cases (group 1) and good in 6, fair in 2 and poor in 1 cases (group 2). Radiologically, post operative average of posterior drawer stress view was 5.2 mm (group 1) and 5.0 mm (group 2). Almost double the operation time was taken to reconstruct posterior cruciate ligament by arthroscopic method than open method. There were technical errors in 2 cases performed by arthroscopic method. CONCLUSIONS: The results of both methods had no significant difference. We think that the reconstruction of PCL using patellar tendon by open method is a recommendable treatment method together with arthroscopic method, if the merits or demerits of both methods are considered carefully. But more long-term follow-up is necessary to compare the results of PCL reconstruction by open and arthroscopic methods.

MR arthrography is a useful modality for evaluating the labrocapsular ligamentous complex (LCLC) of the shoulder. This study was performed to describe normal anatomic variations and pitfalls in image interpretation related to evaluation of the LCLC. MR arthrogram of 56 shoulders in 41 asymptomatic young, active, male volunteers were prospectively reviewed to evaluate the labral shapes, capsular insertions and images which may mimic the lesions of glenohumeral instability. The anterior and posterior parts of the labra, respectively, varied in shape: triangular (72%,36%), round (13%,35%), cleaved (8%,1%), notched (2%,0%), flat (5%,24%), and absent (0%,4%). The anterior and posterior capsular insertions, respectively, varied in site: Mosely and Oevergaard type I (82%,62%), type II (13%,36%), and type III (5%2%). A number of pitfalls in image interpretation were discovered. Articular cartilage undercutting the labrum (29%) and middle glenohumoral ligament in proximity to anterior labrum (5%) simulated a labral tear. Joint fluid interposed in the central, superior portion of the sublabral sulci (25%) simulated a SLAP lesion. Synovial fold (38%) in the axillary pouch resembled a loose body. Knowledge of normal variations and pitfalls in MR arthrogram image interpretation of labral-capsular-ligamentous complex will help the orthopedist to accurately detect debilitating derangements associated with the glenohumeral instability.
