  • A 13-month-old, 3.3 kg castrated male Shih-tzu presented with right hindlimb lameness. The physical examination revealed atrophy of the right thigh muscles, hyperextension of the stifle joint and external torsion of the tibia. On the radiographic examination, patella alta and genu recurvatum were observed. A biapical deformity of the tibia and external torsion of the distal tibia were detected by computed tomography (CT). A three-dimensional (3D) printed bone model was designed and constructed for the preoperative plan prior to surgery. Rectus femoris muscle transposition, femoral shortening ostectomy and open wedge osteotomy of the distal tibia were performed using hybrid external skele/t0al fixation (hybrid-ESF). A dynamic stifle flexion apparatus was used to prevent recurrence of a quadriceps contracture (QC). Intense physiotherapy was administered postoperatively. The dog began to use the affected limb one week after surgery. Functional improvement in the affected limb was observed, and full weight-bearing was possible at 3 months after surgery. Union of the osteotomy lines was observed at 3 months, and the stifle joint was fully movable at 7 months after surgery. Regarding the treatments for QC, these methods may be excellent candidates, as they do not lead to severe damage to the limb or amputation.

  • PURPOSE. The purpose of this research was to evaluate the amount of reosseointegration after counter torquing (reverse torque) and transposing the installed implants at different times. MATERIALS AND METHODS. This study was done on ten tibiae of five cross-bred dogs. At the first day one implant was installed in each tibia. After one week half of the implants were randomly counter torqued (1WCT) and the other half were explanted and reimplanted in a new juxtaposition site (transposed)(1WT). At the same time three new implants were installed in each dog, one of them was considered as one week control (1WC) and remaining two as 8 week groups (8WCT&8WT). After eight weeks the 1WCT and 1WT implants were loosened by counter torque and the quantity of needed force for liberation was measured with the digital device (BGI). At the same time one implant was installed in each dog as eight week control (8WC) and the same protocol was repeated for 8 week groups after another 8 weeks. RESULTS. All implants were osseointegrated. Mean quantities of osseointegration in case groups indicated better amounts rather than control groups. CONCLUSION. Counter torque or transposition of the installed implants one week or eight weeks after the implantation did lead to osseointegration.

  • This study was performed to investigate nutritional effect of various dietary fibers on lead absorption and metabolism of protein and lipid in growing rats. Forty eight male rats of Sprague-Dawley strain weighing 75.7$\pm$0.7g were blocked into six groups according to body weight and fed six kinds of diet different with fiber source(non-fiber, cellulose, pectin) and lead level(0%, 1% ) for 4 weeks. Results are summerized as follows: 1) Food intake, weight gain, FER and PER were remarkably decreased in lead(Pb) added groups, and FER and PER in Pb-added pectin group were significantly lower than those in Pb-added non-fiber group. 2) Weight of liver, kidney and epididymal fat pad, bone weight and length, hematocrit, and hemoglobin content were decreased in Pb-added groups. 3) Total protein content in serum was tended to be decreased in Pb-added groups, but total lipid and cholesterol contents in serum were not different with dietary Pb level and fiber source. 4) Nitrogen, lipid and cholesterol content in liver were tended to be deceased in Pb-added groups, and especially those of the Pb-added pectin group were the lowest among groups. 5) Daily urinary and fecal excretions of nitrogen, lipid and cholesterol were decreased in Pb-added groups. Especially fecal excretions of nitrogen, lipid and cholesterol in Pb-free groups were significantly increased by dietary cellulose and pectin. 6) Pb content in blood was significantly increased in Pb-added pectin group. There was no significant decrease in Pb contents of liver, kidney and tibia, and increase in excretion of Pb by feeding dietary fibers. In conculsion, dietary fibers had no effect on the absorption of Pb, and dietary pectin seemed to increase Pb poisoning by decreasing bioavailibility of protein, lipid and other nutrients in the diet.

  • 돼지고기 섭취 시 우리 체내에 축적되는 납의 중독을 완화시킬 수 있는가를 살피고자 흰쥐에 7주동안 납의 임상적인 중독현상을 유발시키고 이어서 7주 동안 납을 중단하고 해독과정을 유발시키면서 돼지고기 투여에 의한 납 해독 효과를 비교하는 시험을 실시하였다. 납 중독에 의해 체중저하, 헤모글로빈과 헤마토크릿 저하, 상대적 간과 신장의 무게 증가, 대퇴골, 신장, 간에서의 납 축적 등을 확인하였다. 해독 시에 돼지고기를 섭취시킨 경우 유의적으로 식이 효율이 높아졌다. 또한 돼지고기 섭취가 상대적 간과 신장의 상대적 무게에 영향을 주는 인자인 것으로 나타났다(p<0.05). 간에서의 납 축적에 영향을 미치는 요인으로는 납 중독 여부(p<0.0005), 돼지고기 섭취(p<0.0005), 납과 돼지고기 섭취의 상호작용(p<0.0005)이 모두 작용하는 것으로 나타났다. 간에 있는 DALAD함량은 대조구에 비해서 돼지고기 첨가구에서 납 첨가 수준에 관계없이 유의적으로 높아졌음을 볼 수 있었다. 이 결과로서 돼지고기가 납에 중독된 흰쥐에서 해독과정을 향상시킬 수 있는 것으로 사료되었다.

  • The fibrous dysplasia is a progressive and disabling condition that lead to deformity, especially weight bearing bones. The morbidity that is associated with the polyostotic fibrous dysplasia is the recurrent fracture and deformity. Various methods of treatment had been failed to control this problem. We used osteotomy and reconstruction nailing for polyostotic fibrous dysplasia occured in the proximal part of right femur with varus deformity and reconstruction nailing in left femur without osteotomy, and interlocking intramedullary nailing in right tibia to prevent pathologic fracture. These methods brought a good result of bone union and full weight bearing ambulation after 1 year and 6 month follow up. We think these methods are useful methods to control refracture and deformity, so we reported this case with bibliographic reviews.

  • High ankle sprain (distal tibiofibular syndesmosis injury) occurs from rotational injuries, specifically external rotation, and may be associated with ankle fractures. The prevalence of these injuries may be higher than previously reported because they may be missed in an initial examination. Syndesmosis injury can lead to significant complications in injured ankle joints, so a precise physical examination and radiological evaluation is necessary. The most important treatment goal is to have the tibia and fibula located in the correct position with respect to each other and to heal in that position. The methods to fix these injuries is controversial.

  • To study the effects of the age and the dietary protein content on Ca metabolism male rats of 1 month 6 month 12 month of age were fed experimental diets containing 5%, 15% or 50% casein for 4 weeks. Food and ca intake were higher in old rats and in high protein groups. The weight ash and Ca contents of femur and tibia were higher in old rats. The higher dietary protein level resulted in higher skeletal weigh ash and Ca contents. But high protein diet(50% casein) lead to reduced bone mineral density(ash/dry bone weight) and Ca density(Ca/dry bone weight) in 1 month old rats. Low protein diet(5% casein) on the other hand reduced the bone growth even though the bone density was higher in this group. The ill effect of low protein diet was not evident in 12 month old rats. Glomerular filteration rate(GFR) and urinary Ca excretionincreased with age and with dietary protein level especially in 12 month old rats. Serum immunoreactive parathyroid hormone(iPTH) level tended to be higher in aged rats but was not affected by dietary protein level except 1 month old rats where 50% protein group showed significantly higher value. This study showed that the dietary protein level seemed to have different effect on Ca metabo-lism in rats of different age., The low bone density in the high protein group of growing rats may be due to the higher iPTH level and increased urinary Ca. The dietary protein level however had no effects on the bone composition in aged rats even though the higher urinary Ca excretion. In conclusion this study suggests that high protein intake from young may lead to less peak bone mass and to increase the bone loss in later years, which would increase the risk for osteporosis.

  • 금속성 임플란트 삽입과 관련된 만성 염증 상태는 미만성 거대 B세포 림프종 발생의 위험 요소이다. 금속 이온은 림프종의 발병에 중요한 역할을 하는 것으로 알려져 있다. 저자들은 15개월 동안 근위 경골에 금속성 임플란트가 삽입된 환자에서 발생한 드문 미만성 거대 B세포 림프종 증례를 보고하고자 한다. 초음파 및 자기공명영상을 촬영하였으며 현저한 골 파괴 없이 불균형적으로 큰 골외 연조직 종괴와 골수 침범이 관찰되었다. 금속성 임플란트 삽입과 관련된 여러 합병증들이 있으며 오진하면 잘못된 치료로 이어질 수 있다. 따라서 금속성 임플란트로 인한 만성 염증 상태와 연관된 림프종과 임플란트 주위에 발생할 수 있는 다른 양성 병변 및 악성 연조직 종괴를 감별하는 것은 어렵지만 매우 중요하다.

  • 역사적으로알파인스키부상은스키장비의발달과밀접한관련을가지고변화하여왔다. 근래에일어난스키장비의혁명으로인하여스키부상은또다른양상으로바뀌어가고있는추세이다. 현대적인스키, 스키화, 바인딩의개발로과거에빈발하던경골간부골절이나족관절손상은1970년대말에이르러90$\%$ 가까이감소하였다. 하지만1980년대에들어서전방십자인대손상을포함한심한슬관절손상은 약3배가까이증가하였으며,장비의개발에도불구하고전방십자인대손상을줄이지못하고있다. 최근에는슬관절이하의하지손상및전방삽자인대손상발생율모두변화가중단된상태이다. 최근스키디자인을완전히바꾸어놓은카빙스키는전통스키에비하여상급자에게전방십자인대단독손상의위험성을증가시키는것으로보인다. 대신초급자에게는족관절손상의위험성이높다. 스키로인한하지손상율을더욱낮추기위해서는스키전문점의스키기술자가ASTM (American Society for TestingMaterial)의표준에따라장비를관리하도록유도하여야한다. 현재까지개발된스키장비중전방십자인대손상을줄일수있는것으로검증된것은없다. 효과가입증된유일한방법은,위험한상황을인식하여그것을피하는방법을익히는트레이닝프로그램뿐이다.
