Syndactyly is one of most common congenital anomalies of the limb. We reviewed 89 webs of 40 patient with syndactyly which had been treated at Seoul National University Hospital from 1979 to November 1984. It is the purpose of this article to compare the operative methods used in the treatment of syndactyly. In our hands, using the volar interdigital flap in the treatment of syndactyly gives the most excellent postoperative result in both function and cosmesis.

CT and myelography, separately or combined together, have been used for the study of spine lesion. Metrizamide enhanced CT is a new diagnostic modality for the study of spine lesion. The purpose of this study was to compare the efficacy of metrizamide enhanced CT with those of CT and metrizamide myelography. Among 163 surgically proven cases, metrizamide CT was carried out on 49 cases, CT on 50 cases and myelography on 64 cases, at Department of Orthopedic Surgery, Seoul University Hospital for 3 years period from August 1981 to July 1984. 1. Overall diagnostic accuracy of CT was 90%, that of metrizamide myelography was 82.8%and that of metrizamide CT was 93. 9%. 2. Diagnostic accuracy of metrizamide CT in HIVD was 95%, in spinal stenosis 94.4% and in spondylolisthesis 80%. 3. Most of complications were observed in myelography, even they were minor. 4. It was concluded that plain CT was advisable on a clinically typical HIVD, considering complications and expenses of myelography and metrizamide CT. 5. Metrizamide CT was indicated on previously operated cases or atypical HIVD, spinal stenosis and spondylolisthesis.

Although the incidence of tuberculous arthritis of the hip is being decreased with improvement of hygiene and preventive measures and chemotheraphy, it remains as important disease in orthopedic surgery. In order to evaluate which treatment is best in the view of eradication of the tuberculosis and preservation of the function, seventy two patients of tuberculous arthritis of the hip who were treated at the Department of Orthopedic Surgery, Seoul University Hospital for periods of 14 years between January 1970 and August 1983 were analysed clinically. The results are as follows: 1. Age distribution showed that patients below 15 years were thirty (41.7%) and those above 16 years were forty two (58.3%). 2. Onset of the symptoms above 1 year occupied forty two patients (58.3%). 3. Duration of follow up is between 1 year and 14 years with average duration of 3.5 years. 4. Recurrence rate according to the modality of treatment was 12.9% as 4 cases among 31 cases of hip fusion group, 15,2% as 5 cases among 33 cases of synovectomy group, and 28.6% as 2 cases among 7 cases of conservative group. 5. Follow up of the functional evaluation of the hip was 92.9% of “above Fair” as 26 cases among 28 cases of synovectomy group, 60% of “above Fair” as 3 cases among 5 cases of conservetive treatment group, and 25.7% of “above Fair” as 9 cases among 35 cases of hip fusion group. 6. Although the recurrence rate of synovectomy group is a little higher than that of hip fusion group, synovectomy is a better treatment in the view of the preservation of the function of the hip considering Korean life style.

Photoplethysmography(PPG) employs an infrared light-emitting diode to transmit light into the skin noninvasively. Light reflected from blood cells is received by a photocell or phototrotransistor which permits recording of the pulsatile cutaneous microcirculation. The use of PPG for vascular measurements in extremities is not new. Since Hertzmann, in 1938, first described the technique to measure skin blood flow, a few investigators have used PPG for clinical application. However, experimental reports on the photoplethysmographic assessment of blood flow after arterial reanastomosis are rare. We assessed the changes of blood flow after reanastomosis of the femoral artery in rabbits using photoplethysmography. We divided 20 rabbits into 3 experimental groups. In Group I, the femoral artery was surgically exposed and clamped for 60 minutes. In Group II, the femoral artery was surgically exposed and clamped, as in Group I, and then severed and anastomosed crudely in order to creat thrombus formation. In Group IU, the femoral artery was prepared as Group II and then anastomosed carefully to ensure patency. Blood flow was measured by photoplethysmography on the anteromedial aspect of the right hind leg, every 15 minutes for the fisrt 2 hours, at the 3rd day, I week, and II weeks post-operatively. The following results were obtained l. After the removal of vascular clamp, the mean time for the pulse wave to return to normal form was 63±24.0 minutes in Group I and 63±18.7 minutes in Group III. There was no statistically significant difference beween the two groups. When the wave form was normalized, it remained so continuously. 2. After the removal of vascular clamp, the mean time for the wave amplitude to return to normal was 108±11.2 minutes in Group I and 102±16.4 minutes in Group III. There was no statistically significant difference between the two groups. 3. The thrombosis which obstructed blood flow was formed within the first 60 minutes(mean time: 49±12.4 minutes) in all the animals in Group II. When the thrombosis was formed, it was readily detected by the change of wave form and by decrease in amplitude. 4. It is concluded from this experiments the changes of blood flow after reanastomosis of the femoral artery in rabbits were accurately assessed by PPG. It is suggested that PPG can be used clinically in monitoring blood flow after arterial reanastomosis.

Recurrent dislocation of the patella is a relatively uncommon disease, which is most commonly seen in females in late adolescence. The condition is usually spontaneous and only rarely fallows traumatic dislocation. Dislocation is nearly always lateral and about one thirdis bilateral. The theoretical rationale of the treatment of the recurrent dislocation and subluxation of the patella is the realignment of the extensor mechanisms. We experienced with recurrent dislocation and subluxation of the patella on 22 knees in 18 patients at Seoul National University Hospital from July 1981 to Oct. 1987 and obtained the following results. 1. The age at operation ranged from 4 to 33 years and its mean was 15.8 years. Among 18 patients thirteen were female and five, male. 2. The most common presenting symiptom was pain (11 knees) and the most common presenting sign was quadriceps muscle atrophy (11 knees). 3. The prominent radiologic finding was patella alta in 6 knees (27.3%), genu valgum in 10 knees (45.3%), and hypoplasia of the lateral condyle of the femur in 2 cases (9%). 4. In two knees supracondylar osteotomy were performed and followed by proximal extensor mechanism realignment. In twelve knees only proximal reconstruction was performed. Four knees were treated by Hauser's technique and three knees with Roux-Gold-thwait technique. And these distal reconstruction procedures were performed with other procedures. 5. Mean follow up period was 1 year and 5 months. And the results are excellent in 8 knees, good in 12 knees and fair in 2 knees.

During the period from January 1987 to May 1988, arthroscopic partial meniscectomy had been performed in 95 knees of 94 patients. Of the 94 patients, there were 66 males and 28 females ranging in age from 10 to 49 years(mean, 27.4 years). The mean follow up period was 22.1 months (range, 15 to 32 months). Both medial and lateral menisci were affected in 6 knees, so 101 menisci were removed. In the group studied, there were 35 tears of medial, 29 tears of lateral and 37 tears of discoid meniscus. In the 101 tears of meniscus, 22 cases of longitudinal tear, 37 cases of bucket handle tear, 19 cases of flap tear, 13 cases of transverse tear, 5 cases of horizontal tear and 5 cases of complex tear were observed. Most frequently associated lesion was ACL injury (9 cases), and 4 cases of loose body and 4 cases of synovial plica syndrome were also found. The sensitivity of diagnosis with physical examination only was 63.6% and improved with arthrography to 70.4%, and with arthrography and CT to 80.0%. Satisfactory result including excellent and good was 76.6% and no major complication was accompanied.

From March 1988 to August 1989, 51 knees with clinically suspected meniscus injuries were examined by both MRI and arthroscopy and compared their findings prospectively on the basis of arthroscopic findings to determine the accuracy of MRI in detecting meniscus injury of the knee. We used 2.0 tesla superconducting magnet imager(Spectro-20000, GoldStar, Korea) to obtain MR imaging. Our protocol for imaging was producing Tl sagittal images by spinecho technique and T2 coronal images by gradient echo technique, interleaved at 4mm continuously while the patient's knee was in 8–10 degrees of external rotation and surface coil was placed posteriorly to the knee in supine position. We grouped and correlated the findings of MRI with the arthroscopic findings. With this noninvasive MRI, we could obtain multiplanar, high quality images without compliations. Compared with the arthroscopic findings, MRI resulted in a high diagnostic accuracy of 96 and 86 percent for the medial and lateral meniscus, respectively. And it aided in optimal surgical planning for the clinically suspected meniscus injuries.
