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.

Omentum has the characteristic that it readily develops vascular anastomosis with adjacent tissues. It is suitable for eliminating a dead space regardless of the size, shape or site in the treatment of chronic osteomyelitis by use of technique of microvascular anastomoses. We report a case of chronic osteomyelitis treated by transplantation of autogenous omentum with microvascular anastomsis.

Great efforts have been expended to compensate for nerve gap in the repair of a peripheral nerve injury. And yet, this nerve gap presents a great problem in surgical management. End-to-end anastomosis is most frequently used for repair of peripheral nerves, but the main problem is tension at the suture site. The purpose of this experiment is to observe the relationship between the tension and the nerve healing, when stretching is applied to the suture site of the peripheral nerve trunk. We used 25 rabbits of both sexes divided into 5 groups according to the nerve gap and the period of immobilization for this study. Gross and histological examination were used to compare the results of end-to-end suture under a tension and suture without tension. We concluded that: 1. The best results were obtained when end-to-end suture was done without tension. 2. Direct suture under a tension produced the results quite inferior to that of the suture without tension. 3. Better results were obtained from the group of immobilization, at least, for 4 weeks among the tension group. 4. Immobilization period may be prolonged according to the degree of the tension affecting the suture site. 5. Tension at the suture site causes proliferation of connective tissue.
