Peterson's hernia is an internal hernia that can occur after Roux-en-Y anastomosis. It often accompanies small bowel volvulus and is prone to strangulation. Reconstruction of intestinal continuity after massive small bowel resection in a patient who undergoes near total gastrectomy and Roux-en-Y anastomosis can be difficult. A 74-year-old man who had undergone a near total gastrectomy and Roux-en-Y gastrojejunostomy for stomach cancer presented with abdominal pain. The preoperative computed tomography showed strangulated small bowel volvulus. During the emergent laparotomy, we found a strangulated Peterson's hernia with small bowel volvulus. After resection of the necrotized intestine, we made a new Roux-en-Y anastomosis connecting the remnant stomach and the jejunum with a transverse colon segment. We were safely able to connect the remnant stomach and the jejunum by making a new Roux-en-Y anastomosis utilizing a transverse colon segment as a new Roux-limb by two stage operation.

Augmentation rhinoplasty is one of the most popular aesthetic procedures in Asians. Numerous alloplastic implants have been used, however alloplastic implants may cause many problems in nasal and perinasal areas because of thin soft tissue cover. For these reasons, an ideal implant should be nonpalpable, readily exchangeable and biocompatible. Among these alloplastic implants, Gore-Tex(R) is a polymer of carbon bound to fluorine composed of solid nodes connected by very fine fibers. It has been reported that this material become permeated and surrounded by mature connective tissue, forming a strong supporting envelop for the material, yet the implant is easily removed because of limited tissue ingrowth. Since it's development, Gore-Tex(R) has found many applications in the field of facial plastic and reconstructive surgery. From November, 2001 to December, 2002, Gore-Tex(R) implants were removed from 17 patients due to several problems such as; decreased dorsal height, tip deformity, chronic inflammation. The implants were very hard to remove and coinciding injury of the surrounding tissue were inevitable. An analysis of the length and thickness changes in these removed implants was made. The results showed, decrease in length and thickness with a volume loss averaging, 46.3% in 45x4.0mm implants, 49.3% in 50x5.0mm implants. In view of the experiences of 17 cases of Gore-Tex(R) implants in rhinoplasty, we have concluded that Gore-Tex(R) implants were structurally unstable, fibrovascular tissue ingrowth into pores were minimal, the implants were very hard to remove and the implants caused a postoperative volume reduction. Therefore, Gore-Tex(R) use in augmentation rhinoplasty should be approached with caution.

To measure the mutagenic activity of micro-organic pollutants in drinking water, mutagenic test was conducted using Salmnella typhimurium TA 98 strain on the water sample taken from three water supply station and six tap water in Seoul in July and November 1987. The results were as follows : 1. The average amounts of organic matters in raw, treated, and tap water sampled in July were 0.38mg/l, 0.28mg/l, and 0.45mg/l, respectively, and sampled in November were 0.34mg/l, 0.24mg/l, and 0.22mg/l, respectively. The amount of organic matters of tap water sampled in November did not increase while that of tap water sampled in July increased compare to those of raw or treated water. 2. The amount of organic matters is the highest in neutral fraction compare to acidic and basic fractions. 3. In the five out of six tap water and raw water of Paldang and Kuui station sampled in July, the mutagenic ratios were greater than two (both direct and indirect mutagenicity). 4. In the three out six tap water and raw and treated water of Kuui station sampled in November, the mutagenic ratios were greater than two. 5. While mutagenic were low in acidic and basic fraction, they were high in neutral fraction. The samples which had high mutagenic activity in the total amount also showed high mutagenic activity in neutral fraction. 6. While mutagenic activity was decreased after the treatment of water, it was increased in tap water as the distance from the water supply station increases.

Various methods of taking of optic foramen view and avalubilities have been studied by many foreigninvistigators, but those in Korea have not been reported yet. The authors have measured and examined the size andshapes of optic foramina of optic foramen views in 111 Korean checked at Inje Medical College Hospital duringabout 3 years form June 1979 to March 1982. The cases were divided into gwo groups, A and B, for the convenienceof study. Group A consisted of 50 normal Korean 5 to 55 years of age with no visual symptoms and signs. Group Bincluded 69 patients 3 to 75 yrs of age with visual symptoms and signs. The results were as follows; 1. Mean valueof actual diameter of optic foramen meassured by Goalwin's method in Group A; Right; A diameter; 4.21mm, Bdiameter; 4.32mm, Left; A diameter; 4.29mm, B diameter; 4.30mm. 2. Absolute symmetry of the greatest diameters ofboth optic foramina in Group A; 36%, difference of 0.5 or lessl 28%, from 0.5 to 1.0mm; 18%, from 1.0 to 1.5mm;8%, uncomparable cases; 10%. The greatest difference was 1.4mm. 3. The shapes of optic foramen in Group A; ovalshape; 65%, circular ; 29%, keyhole or double foramen; 6%. 4. In Goup B, the peak age group was second decade(31%), the most comon clinical cause of examiniation of optic foramen view was optic nerve atrophy(30%), and thepathologic findings were only 4 cases(7%). 5. The technique of optic foramen view by modified Pfeiffer's methoddelineated the outline of optic foramen more clearly than ordinary Rhese's method in our experience.

The increased knowledge of the cutaneous circulation of the body and refinements in surgical technique have provided the basis for the successful microvascular transfer of various muscle, skin and myocutaneous free flap. We have found the tensor fascia lata(TFL) inyocutaneous flap to be reliable one and its transfer as a free flap. The TFL myocutaneous free flap was first introduced by Hill et al in 1978 and our two cases report were first introduced in Korea. Two cases of microvascular TFL myocutaneous free flap transfer were performed at the department of Orthopaedic Surgery of Hanyang University Hospital and satisfactory result was obtained from the one of those.

Chronic osteomyelitis continue to be a therapeutic challenge. The osteomyelitis also implies chronic ischemia of the diseased bone ; thus systemic antibiotic treatment may not be as effective as we want. In 1972, Klemm developed a new procedure to supplement saucerization in the treatment of chronic osteomyelitis, alternative to irrigation and suction-drainage, i.e., Gentamicin-PMMA Beads. The authors analysed 35cases of the chronic osteomyelitis which were admitted and treated by sauceriztion and Gentamicin-PMMA Beads in Department of Orthopaedic Surgery, Korea Veterans Hospital from Aug. 1984 to Jan. 1988.

PURPOSE: To evaluate the clinical characteristics of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures and assess the surgical outcomes of a novel, closed intramedullary nailing surgical approach designed to minimize fixation failure. MATERIALS AND METHODS: Between May 2013 and April 2017, 31 patients with intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures treated with closed intramedullary nailing or long proximal femoral nail antirotation (PFNA) were enrolled in this study. Preoperative data included age, sex, injury severity score, body mass index, location of shaft fracture, injury mechanism, accompanying traumatic injury, walking ability before injury, and surgical timing. Perioperative outcomes, including follow-up period, types of intramedullary nails, number of blocking screws used, operation time, and blood loss were assessed. Radiologic outcomes, including union rate, time from surgery to union, and femoral shortening, and clinical outcomes, including hip flexion, walking ability, and Harris hip score were also evaluated. RESULTS: A total of 29 unions (93.5%) were achieved. The time to union was 16.8 months (range, 11–25 months) for hip fractures (15.7 weeks for intertrochanteric fractures and 21.7 weeks for subtrochanteric fractures) and 22.8 months for femoral shaft fractures. There were no significant differences in surgical outcomes between the two groups except for type of intramedullary nail. CONCLUSION: Closed intramedullary nailing in the treatment of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures may be a good surgical option. However, fixation of femoral shaft fractures might not be sufficient depending on the implant design.
