Recently, the Supracondyle fracture of the femur is so severe and comminuted that it is difficult to treat open reduction and rigid fixation sufficiently due to violent traffic accident and external forces. The associated injuries are accompanied variously. So compliactions of the supracondyle fractures 'including joint.. stiffness, delayed union, infection are serious. However development of internal implant and operation skill result in relatively satisfactory function than conservative management. The authors reviewed. 20 cases of the supracondyle fracture of the femur treated at Yeungnam University Hospital from 1989. Dec. To 1992. Jan. The results were as follows 1. The male was common(70%). The 2nd-4th decade was most(87%). 2. The most common cause of injuries was traffic accident. The rate of open fracture was 35%, most of it was traffic accident. 3. According to the ASIF group classification, 4 cases were type A, 4 in type B, 12 in type C (10 in type C2&C3). 4. Accompanied injuries included multiple fractures in 9 cases and femoral artery injury in 1 case. 5. Among the 20 cases, conservative treatment was done in 5 cases and operative treatment was done in 15 cases. 6. Functional results (by Schatzker criteria) were as follows. The satisfactory results were achieved in 40% of cases in consevative treatment and 67 in operative treatment. 7. The average time of partial weight bearing was 15 weeks. 8. Complications were knee stiffness in 6 cases and 4 in delayed union.

Treatment of the olecranon fractures by prolonged immobilization often results in limited elbow motion. With the use of tension band wiring, anatomical reduction was obtainable, and only a short period of immobilization was needed. We reviewed the cases of 17 patients who underwent surgical treatment of the olecranon fracture. All patients were treated by tension band wiring. In the overall series, we were able to obtain 53 percent excellent, 30 percent good, and 18 percent fair results.

Fractures of the tibial shaft are the most common among the long bone fractures, and have much difficulty in treatment due to their numerous complications. Thirty patients with fractures of the tibial shaft were treated with Ender nails under the image intensifier at the Department of Orthopedic Surgery, Yeungnam University Hospital from December 1986 to November 1991. The following results were observed. 1. The average age was 37.3 years and the number of male was three times of the female. The most common cause was traffic accident. 2. Twenty cases out of thirty one were closed fracture and the remaining 11 were open. The comminuted and segmental fractures were 18 (57.7%) in number and the most common fracture site was the middle one third (53%). 3. Average interval from injury to operation was 7.6 days and 19 cases showed associated injuries. 4. The mean duration of the bone union was 18.9 weeks and 2 cases showed the delayed union. 5. Twelve complications were noted such as shortening, varus deformity, delayed union, ankle motion limitation, nail irritation, and soft tissue infection.

The biocompatibility of the titanium has been estabilished through various experimental studies such as cell culture toxicity test, pyrogen test, mutagen test and others. In order to confirm biocompatibility after fabrication of titanium and to clarify the difference between the bone reaction after insertion of the lathed titanium rods and the bone reaction after insertion of the finished and polished rods, both rods were implanted into the proximal femur of a rabbit. Histologic reactions in the bone were observed according to the ASTM standards at the intervals of 6 weeks, 12 weeks and 26 weeks after implantation. The result were as follows In 6 weeks after implantation of lathed titanium rods, inflammatory reactions, such as minimal degree infiltration of polymorphonuclear leukocytes and lymphocytes were observed in all cases. This was thought to be caused by surgical trauma. However, inflammatory cell infiltration was not seen after implantation of polished and finished rods in all cases. The cellular infiltration and the histologic reaction of the bone after implantation of lathed group were significantly more pronounced than those after implantation of the finished group. In 12 weekt after implantation of lathed rods, two of four cases revealed a minimal degree of cellular infiliration and histologic reaction seemed to be more pronounced in the lathed group, but they were not significant statistically.

We perfomed this study to evaluate the incidence of the oculocardiac reflex(OCR) and its difference relative to each extraocular muscles. In addition, preventive methods for oculocardiac reflex were also evaluated. From Febrary 1997 to January 1998, we examined the occurrence of the OCR of 65 patients who underwent strabismus surgery in 123 extraocular muscles under the general anesthesia. Those who showed severe OCR were prepared with retrobulbar injection of 1% lidocaine 2cc or 1% intravenous atropine and observed wheather OCR was prevented. The overall incidence of the OCR was 66.2% and there was no significant difference between the incidence in both eyes(p>0.999). The incidence in each of the extraocular muscles did not show statistically significance when the patients were prepared with preoperative intramuscular atropine(p=0.018). The incidence after intraoperative retrobulbar injection or intravenous atropine was decreased to 27.3% but was not statistically significant(p=0.34).

Four patients with advanced tuberculosis of the wrist joint were treated with curettage & radial sliding graft to obtain radiometacarpal fusion. After each follow-up, their results were complete relief of pain with eradication of focus and solid union. This graft affords the stability of cortical bone combined with the osteogenesis of cancellous or trabecular bone. It furthermore affords a shape that conforms to the desirable dorsiflexion of the wrist after fusion.

A bloodless field is essential for orthopedic surgery. Although a touriquet is necessary, it is dangerous because of soft tissue damage. We studied the soft tissue pressure beneath a tourniquet in the thigh to identify the accurate pressure for the bloodless field, and recovery time of normal blood flow after tourniquet release as related to the time of tourniquet use. From June, 1986, to Marth 1987, the soft tissue pressure of 21 lower extremities beneath the tourniquets was measured by the slit catheter method, and the noraml blood flow recovery time of 21 lower extremities after the tourniquet release was measured by a photoplethysmograph. The results were follows : Tourniquet pressure of 400 mmHg was enough for a bloodless field. So we can prevent the tissue damage due to excessive tourniquet pressure. The soft tissue pressure beneath a tourniquet was not affected by the age, weight, height or thigh circumference of the subjects. The recovery time to normal blood flow after tourniquet relase was prolonged with the time of tourniquet use. The recovery time to normal blood flow after tourniquet relase was not affected by age, weight, height, or thigh circumference of the subjects.
