The suture materials influence the success of microvascular anastomosis importantly. The purpose of this experiment is to observe the effect of absorbable suture material and nonabsorbable suture material in microvascular anastomosis. The study was carried out on one side of carotid arteries of fourty rats which were anesthetized intraperitoneally with urethane. The experimental procedures differed in two groups, Group A in which the carotid artery was sutured with 10-0 monofilament polyglycolic acid, Group B in which the carotid artery was sutured with 10-0 monofilament nylon. Gross and histological examination were used to compare the results of end to end suture above two suture material. The results were as follows. 1. Nylon had greater tensile strength and ease of handling than polyglycolic acid, but held knots poorly. 2. Polyglycolic acid had difficult handling and lesser tenslie strength than nylon, but held knots hardly. 3. Polyglycolic acid had high patency rate, some lesser tissue response than nylon.

Proximal tibial osteotomy is a procedure usually employed for osteoarthritis of the knee with a predominant single compartment involvement accompanied by pain and angular deformity. It has as its objective the shift of the gravitational line of weight from an involved to a relatively uninvolved side of the knee. We studied the preoperative clinical status and postoperative results in twenty-two patients (twenty-four knees) who had had a proximal osteotomy for osteoarthritic varus deformity. The mean length of follow-up was 2.6years(Range, 6months to 4.8years). In the preoperative evaluation of the lesion, we used bone scintigraphy to estimate the range and extent of the osteoarthritic change. The scintigraphic results were more sensitive to simple x-ray finding in a disease process. The range of motion of the knee were improved after osteotomy, from 7.7degree-128 degree to 2.6 degree-135degree(5.1degree in flexion contracture and 7 degree in further flexion). Correction of the tibiofemoral angle was performed to the level that we had decided correction angle to 7 degree and 3 degree of overcorrection. The correltion of good clinical results and tibiofemoral angle was dependent on whether the postoperative tibiofemoral angle is more than 5 degree valgus or not.

We analyzed 34 extension contracture of the knee patients after modified Judet's procedure. Male patient was 32 and female was 2. Age ranged from 19 years to 61 years average being 34 years old. Follow-up period ranged from 12 months to 7 years and 8 months average being 3 years 8 months. 1. The extension contracture of the knee were due to not only scarring of the vastus intermedius but contractures of quadriceps muscles, and finally did lead to intraarticular adhesion in all cases. 2. The results of modified Judet's procedure were excellent or good in 97% and we concluded that the modified Judet's procedure of quadricepsplasty was good method of treatment in extension contracture of the knee. 3. The extension lag after modified Judet's procedures was increased initially but overcame by physical therapy, and did not significantly increase even after release of rectus femoris. 4. Modified Judet's procedure was able to permit early physical therapy without any skin problem.

The Saville's index of the lumbar spine and the Singh's index of the femoral neck is very simple method to measure degree of osteoporosis. Authors compared Singh's index and Savilles index with Dual Photon Absorptiometry(D.P.X.) and studied the reliability and clinical usefulness of two indices. We took the D.P.X. and simple L-spine lateral view in 103 patients in same time and also performed D.P.X. and both hips A-P view in 70 patients, then analyzed and compared each two indices with D.P.X. The Singh's index had less interpersonal difference and intrapersonal difference compared with Saville's spine index. There was some confidence of Singh's index and Saville's spine index compared with the D.P.X., but the relationship between Saville's spine index and D.P.X. was less promising than that of Singh's index. Authors suggest that the Saville's spine index has less clinical usefulness than Singh's index in measurement of osteoporosis.

The authors reviewed 73 cases of ligament injuries in 70 patients from October, 1972 to June, 1978 who were admitted and treated in the Orthopedic Department at Kyung Hee University Hospital. Of 70 patients, the sex distribution was 59 patients (84%) in male and 11 patients (16%) in female. The high incidence was in age group from 21 to 40 years, that was 46 patients (55%). Traffic accident was most common cause of ligament injuries that was 61 patients (87%). Methods of treatment were direct repair, reconstruction and conservative treatment. Degree of angle and distance were measured with stress radiogram. Degree of angle and distance were also compared with normal and abnormal knee joints. Eleven cases were treated conservatively, and 62 cases, operatively, of whlch direct repair performed in 56 cases and reconstructive surgery, in 6 casea, The summary were as follows: 1. The result was better in the group with conservative treatment, as compared with operative treatment. And conservative treatment was applied only in single ligament injuries. 2. In normal knee joint, degree of angle was distributed evenly in the range of 0° to 10°, and distance was in the range of 0 to 10 mm. 3. In stress radiograrn, the significance of ligament injuries was present in more than 10° and 10 mm. 4. The measurement of distance seemed to be more meaningful than degree of angle. 5. It is helpful to measure the degree of angle and distance in diagnosis of ligament injuries, though not absolute.

The utility of computed axial tomography(CAT) in the diagnosis of spinal disorders has been the subject of considerable interest since the introduction of CAT scanning. Computed tomographic guided needle biopsy of 12 consecutive patients with a variety of undermined spinal disorders resulted in a 100% yield of positive tissue diagnoses, without signlficant complications. The principal advantage of cat guidance is the continuous direct observation of the needle tip position in relation to the target volume. We think that the application of computed tomographic guided needle biopsy in the lesions of the spine is of great value, because it is the single most accurate method of obtaining diagnosis other than by open surgical biopsy.

From Oct. 1974 to Jun. 1979, 47 diaphyseal fractures of the forearm bones in 36 patients were treated with compression plates. Among them 36 diaphyseal fractures in 28 patients (23 with acute fractures. and 5 with non-union) followed for average 8.3 months from three months to thirty seven months were studied. 19 fractures of the radius and 17 fractures of the ulna were treated with compression plates. Fifteen fractures which were delayed for operation for more than 3 weeks or had severe comminution, had primary iliac bone grafts. The fracture unlon of the radius and ulna was obtained in all cases and average healing time for the radius was 11.9 weeks and for the ulna was 12.3 weeks. The final functional results were excellent, 16 and satisfactory,7. The over all rates of excellent and satisfactory results were 82.2 percent. Therefore compression plate is one of the excellent methods to treat diaphyseal fractures and non-union of the forearm bone.
