The injured tendon is thought to be healed by, extrinsic healing from tendon sheath and adjacent connective tissue, and intrinsic healing from epitenon and endotenon. About the factors influencing the healing of injured tendon, many authors reported the effects of mobilization, electricity, ultrasound and various druge. Especially, active or passive mobilization had been known to promote the healing process and to reduce adhesion. To investigate the influences of active limited mobilization, intrinsic and extrinsic healing process, right Achilles tendons of 30 New Zealand white rabbits were grouped according to the types of treatments (Group I; tenotomy of Achilles tendon only, Group II; Tenotomy and long leg cast, Group III; surgical repair after tenotomy and long leg cast). The tendon sheath was repaired in all the groups, and the left Achilles tendons were used as control. At six weeks after operation, the tendons were removed and analysed biomechanically using Instron 1000, and histologically. The following results were obtained: 1. There were significant decreased of break strength, in order of Group III, Group I and Group II(p < 0.05). But, no difference was found between control group and Group III. 2. Extension length to the rupture, was decreased significantly in the experimental groups than control group. But there was no difference among the experimental groups. 3. Histologically, dense proliferation of fibroblasts and hypertrophy of tendon was observed in Group I; and matured fibricytic tendon tissues in Group II and III. In Group II, the amount of matured tendon tissues and degree of maturity were less than in Group III. In summary, suture and active limited motion were considered as promoting factors on the tendon healing.

The frontal sinus has importance from the aesthetic and functional points of view, so management of the frontal sinus should be conducted. The management may differ with the severity of displacement, the extent of displacement, as well as the involvement of the brain and nasofrontal duct. Fifteen patients with frontal sinus fracture were managed differently depending on the severity of their injuries for between 14 and 31 months, and then evaluated. During the follow-up period, encountered no complications and the overall result of the foreh ead contour was satisfactory.

For treatment of the pressure sore, varieties of methods have been developed such as skin graftings, local flap, myocutaneous or fasciocutaneous flap, etc.. Except mild cases, myocutaneous flaps have been used commonly for the best coverage and padding of the wound. But the gluteus maximus muscle is not an expendable muscle, so the myocutaneous flaps using gluteus maximus muscle result in significant functional loss in ambulatory patients. Various methods as fasciocutaneous flap to reserve a function of the gluteus maximus muscle have been developed. We especially designed a bilateral fasciocutaneous flap in the fashion of interdigitating extended V-Y advancement in sacral sore when the defect is fusiform transversely in shape. With this design, we obtained reduced tension in the midline suture with less dissection in medial portion of the fasciocutaneous flap and made the flap more rleliable by including more parasacral perforators within the flap. We have experienced the eight cases of gluteal fasciocutaneous V-Y advancement flap and obtained the excellent results without flap necrosis. We conclude that a bilateral fasciocutaneous flap in the fashion of interdigitating extended V-Y advancement is useful in sacral sore when the defect is fusiform transversely in shape.

This retrospective study comprise 595 patients with facial bone fractures in various accidents and treated in the department of Plastic and Reconstructive Surgery, the Chung Buk National University Hospital between September 1991 and December 1997. The medical records of these 595 patients were reviewed and analyzed in order to obtain the clinical pattern and understand the therapeutic modalities. The following results were obtained. 1. The most prevalent age group was the third decade(35.1%). 2. The monthly incidence was the highest in September and the most common accident time was between 6:00 p.m. and midnight. 3. The most common etiology was motor vehicle accidents(59.5%) followed by assault(26.2%), fall(11.4%), sports(2.7%). 4. The male predominated over female in 4.27:1 ratio. 5. The most common fracture site was nose(30.0%) followed by mandible(26.7%), zygoma(23.3%), orbit(8.6%), maxilla(8.1%), frontal sinus(3.2%). 6. The most common fracture site of mandible was parasymphsis(34.9%) followed by angle(27.1%), condyle(23.4%), symphysis(14.5%). 7. The soft tissue injury was the most common associated injury(51.1%). Fcial soft tissue injuries were sustained by 53.3% in the highest rate associated with the associated injuries. 8. Open reduction was used for 63.7% of total cases while 33.8% of total cases required closed reduction, and 2.5% of total cases treated conservatively. 9. The complication rate was 14.1% and the ophthalmologic complication rate comprise 44.9% of all complications.

Aconitine is a main component of Aconitum carmichaeli, a Chinese herb known to be effective for arthritis and neuralgia. Many senior citizens consume the herb as a folk remedy. Aconitine-associated cardiogenic toxicity has been observed but aconitine-induced cerebrovascular event has not been reported so far. We report two elderly patients who became unconscious and showed neurological dysfunction soon after ingesting aconitine for pain control. We speculate that the aconitine induced cardiac arrhythmia. This resulted in cardiogenic emboli formation with subsequent large territory cerebral infarction.

Luque introduced new posterior spinal instrumentation by segmental sublaminar wiring for spinal deformity in 1976. This system initially developed for the treatment of paralytic scoliosis, but now its application was extended to treatment of other types of scolisis, spinal fractures and spondylolysthesis. Advantages of this system in scoliosis are better correction force and secure internal fixation enabling early ambulation without external support. Disadvantages include longer operation time, possibilities of epidural bleeding and dural laceration. Luque instrumentation in thoracic and lumbar spine fracture is an effective means of obtaining following goals: provide reduction, maintenance of alignment, restoration of stability, prevention of deformity, low pseudarthrosis rate and early mobilization without external support. Luque instrumentation were carried out in 5 cases at Dept. of O.S. at SNUH from Oct. 1983 to Feb. 1984 with excellent results. The average follow-up period was 7.4 months and there was no complication. Two cases of unstable thoracic and lumbar spine fractures were treated with Luque instrumentation with fusion. The use of double sublaminar wiring with Luque rods, two levels above and two levels below on area of fracture provided early stabilization to allow rehabilitation without external immobilization. Three cases of paralytic scoliosis underwent Luque instrumentation by a modification of the Galveston technique with fusion. Average preoperative curve was 110°(ranged from 101° to 126°). Immediate postoperative correction was 58.7°(46.6%) and average 7 months-following result was 56.3°(48.3%). Operation time averaged 6hr 7min and blood loss was averaged 12 pints. Those patients required instrumentation from the pelvis to middorsal segment, in an effort to control the curve and associated pelvic tilting. In early follow-up the author obtained remarkable correction in paralytic curves, and the pelvic obliquity were well corrected with a pelvis and provid ing with better sitting balance.

In 5 cases of congenital coxa vara, 7 cases of acquired coxa vara and 4 hips in 3 cases of acquired coxa valga, we performed subtrochanteric osteotomies at Department of Orthopedic Surgery, SeoulNational University Hospital, from December 1980 to February 1984. At a relatively short interim follow-up, following observations were made on the correction of the femoral neck-shaft angle deformities. l. In the congenital coxa vara group, at an average follow-up of 1 year and 3 months, 97.9% of the correction obtained by osteotomy was maintained, based on the roentgenographic measurements of femoral neck-shaft angle. In the acquired coxa vara group, at an average follow-up of 1 year and 2 months, 93.3 % of the correction obtained by osteotomy was maintained. In the acquired coxa valga group, at an average follow-up of 1 year and 5 months, 92.9% of the correction obtained by osteotomy was maintained. 2. At final follow-up, leg length gain averaged 1.26cm in the congenital coxa vara group and 2.23cm in the acquired coxa vara group. An average 0.70cm decrease in leg length was noted in the acquired coxa valga group. 3. Trendelenburg sign, which was positive in all the cases of the congenital and acquired coxa vara group, reverted to negative in all. 4. Slight overcorrection in cases of the acquired coxa vara and undercorrection in cases of the acquired coxa valga, is recommended for later loss of surgically corrected femoral neck-shaft angle. In the congenital coxa vara, it appeared that loss of correction was relatively minor.
