목적: 배측 분쇄가 있는 원위부 요골 골절에서 세가지 수술법에 따른 결과를 알아보고자 하였다. 대상 및 방법: 2006년 4월부터 2009년 5월 사이의 60세 이상의 배측 분쇄가 있는 원위부 요골 골절이 있으면서 불안정성을 보인 환자 49명을 대상으로 하였다. 수술 1년 후까지의 방사선학적 추시관찰을 통하여 골절 정복의 유지 여부 및 Mayo Wrist Score를 통한 임상적 결과를 비교하였으며, 일원배치 분산분석(One-Way ANOVA)을 통하여 연관성을 검정하였다. 결과: 세군 모두에서 수술 직후에는 만족스러운 정복을 얻을 수 있었으나, 추시 소견상 외고정장치 단독으로 고정시에는 외고 정장치에 동종골 이식을 추가한 군 및 수장측 잠김 압박 금속판을 사용한 군에 비해서 유의하게 정복 소실이 있음을 확인하였다.(p<0.05) Mayo Wrist Score는 세군 모두에서 의미있는 차이는 없었다. 결론: 배측 분쇄가 심한 원위부 요골의 관절내 골절에서 외고정 장치만 사용한 치료시에는 해면골 결손으로 인한 정복유지의 어려움이 있어 불충분한 치료로 판단된다.

In this paper, the problems of the external fixator that have developed for a distal radius fracture so far are analyzed, and accordingly, the characterizations, which must have a prototype, are arranged. C-Arm is used. This instrument makes it possible for the real play of the internal body by x-ray permeability. From this data, it is possible to induce important design factors. Finally, a basic mechanism, which has to be applied, is decided, and the Solid Edge program, which used a 3-D design tool, completes then total instrument design.

A 5-week old Thoroughbred foal was presented with severe left carpal valgus. Radiographs of the dorsopalmar projections confirmed the deviation was 14 degrees. Surgery using a single-position screw traversing the physis of the distal radius was performed. The limb was almost straight (2 degrees) 3 weeks after surgery. Visual/radiograph follow-up 7 months after screw removal revealed no over-correction after removal of the screw. Transphyseal bridging using a single-position screw without lateral periosteal transection of distal radius was successful for the correction of foals with this condition.

유치근의 치근이개와 만곡에 관련된 형태학적 특성은 치열교환기의 치근 흡수 및 근단 병소의 양상을 결정지을 뿐 아니라, 성공적인 치수치료에 심대한 영향을 미친다. 본 연구는 하악 제 2유구치 근관 만곡의 각도, 반경 및 만곡 시작점을 측정해 봄으로써, 유치근과 근관의 해부학적 형태를 정밀 분석할 목적으로 시행되었다. 연구재료로는 $3{\sim}6$세의 어린이의 제 2 유구치 구내 치근단 방사선 사진 50매를 사용하였다. 근단공이 미완성이거나 흡수된 것을 제외하고, 방사선상의 왜곡이 적으며 근관 형태의 판독이 가능한 것을 선택하고, 자료를 digital image화하여 이미지 분석용 software Scion Image Beta 4.02 (Scion Co. USA)를 이용하여 만곡을 분석하였다. 그리고 Schneider법에 의해 만곡도를 측정하고, Schaefer 등의 방법에 의해 만곡반경을 측정하였으며, 아울러 만곡개시거리를 측정하고 근원심근 간의 비교를 통하여 다음과 같은 결과를 얻었다. 1. 제 2유구치의 만곡도는 근심근에서 $17.3^{\circ}{\pm}5.0$, 원심근에서 $27.9^{\circ}{\pm}6.0$로 원심근에서 크게 나타났다(p<0.05). 2. 만곡반경은 근심근에서 $8.7\;mm{\pm}2.5$, 원심근에서 $5.8\;mm{\pm}1.5$로 근심근에서 크게 나타났다(p<0.05). 3. 만곡개시거리는 근심근에서 $4.1\;mm{\pm}0.6$, 원심근에서 $4.2\;mm{\pm}0.6$로 양 근간에 차이가 없었다(p<0.05).

손목 관절은 신체의 관절 중 가장 많은 골들과 다양한 인대 및 근육 의해 형성되는 복합 관절로 그 해부학적 구조가 복잡하여 이해하기 힘든 관절이다. 손목 관절은 하나의 관절 공간이 아닌 요척골과 근위 수근골 사이에 형성되는 요수근 관절(radiocarpal joint)과 근위 수근골과 원위 수근골 사이에 형성되는 중수근 관절(midcarpal joint) 그리고 원위 요골과 척골두에 의해 구성되는 원위 요척 관절(distal radioulnar joint)로 구성되며 각각의 관절은 정상적으로 각기 분리되어 있다. 손목 관절에 발생하는 질환과 외상에 대해 치료하기 위해서는 손목관절의 정상 해부학에 대한 정확한 이해가 필수적이다. 본 종설에서는 손목관절의 해부학에 대해 자세히 알아 보고자 하였다.

This study was carried out to evaluate the effects of vitamin D nutritional status on bone mineral density of adults (21-49 years). To attain the aim, we measured bone mineral density (BMD) of the subjects at distal radius by single-photon absorptiometry (SPA). Serum level of 25-hydroxyvitamin D(25-(OH)D) , known to be the best indicator of indicator of vitamin D status in humans was analyzed . The factors affecting this vitamin D level were also investigated in autumn in 122 young adults. Serum level of 25-(OH)D was measured by high pressure liquid chromatography(HPLC) and biochemical variables, general health status, time spent outdoors, and dietary intakes of the subjects. BMD of the male subjects was significantly greater than that of female subjects. Weight, activity and total energy expediture (TEE) showed a positive correlation with distal BMD. The mean level of serum 25-(OH)D was 24.4$\pm$11.0 ng./ml and by sex, 26.0$\pm$6.8ng/ml for males and 23.3$\pm$12.3ng/ml for females , the level was significantly higher in male (p<0.01). there was significant correlation between BMD at distal-radius and s-25(OH)D levels (p<0.001). The serum level fo parathyroid hormone (PTH) showed a negative correlation with BMD(p<0.05), with the more obvious correlation in females. Vitamin D intake was estimated to be 3.75$\pm$2.19ug/day in average. Among the nutrients studied, protein ,fat, calcium , and vitamin D intake were positively correlated with distal BMD. When food frequencies were concerned , milk and dairy products showed a significant positive correlation with the BMD level, and driedfoods, eggs , fats and oils, and cereals also showed a positive correlation. Time spent outdoors was estimated to be about 70 minutes in average and positively correlated with the distal BMD level(p<0.01). During the day, the specific time between 12 :00pm and 2:00pm showed the most significant correlation with BMD (p<0.001). Multiple regression analysis with the variables showed that distal BMD could be fit 31.9% by the time spent outdoors a day, intake of Ca and vitamin D, and TEE. The standardized estimates were 0.344 for vitamin D intake, 0.284 for Ca intake 0.179 for the time spent outdoors a day and 0.273 for TEE. For males, s-25*OH)D level, TEE and time spent outdoors during a day showed a significant correlation. For females, intake of Ca and vitamin D could fit about 27.1% of the distal BMD.

Introduction: Ulna is nearly equal to radius in function and bony architecture and strength in forearm. But in lower extremity, fibula is 1/5 of tibia in anatomic and functional point so we can find fibula transposition is commonly used in defect of tibia. We cannot find other article about segmental forearm bone transposition in man. The purpose of this study was to report our clinical and functional result of undergoing segmented transposition of ipsilateral ulna with its own vascular supply in defect of radius in 6 cases. Material and method: From June 1994 to October 2007, 7 segmented bone transpositional grafts in forearm were performed in Kyung Hee Medical Center. The distribution of age was from 20 years old to 73 years old. There was male in 6 cases and female in 1 case. The causes of operation were giant cell tumor in 1 case and traumatic origin in 6 cases; it was nonunion in 2 cases and fracture with severe comminution in 4 cases. Ipsilaterally segmented ulna keeping its own vascular supply was transported to defect of radius in severe traumatic patients and one patient whose tumor in radius had been excised. Transported ulna was fixed to proximal and distal radius remnants by plate and screw. In one case with giant cell tumor, transported ulna was connected to radius across wrist joint as wrist joint fusion. Joint preserving procedures were performed in 6 cases with crushing injury of radius. Results: We could obtain solid bony union in all cases and good functional results. The disadvantage was relative shortening of forearm, but we could overcome this problem. Conclusion: We think that ipsilateral segmented ulna transposition keeping its own vascular supply to radius can be perfomed with one of procedures in cases with wide defect in radius.

A male, 11-month-old, Shih-tzu dog weighing 5.2kg showing knuckling secondary to severe cranial bowing of left antebrachium with valgus deformity of the carpus was presented to the Veterinary Medicine Teaching Hospital of Seoul National University. Radiographic findings were a premature closure of the distal ulnar physis, a cranial bowing of the radius, subluxation of the elbow joint, and degenerative changes in the carpal joint. The patient was treated by performing an oblique osteotomy of the radius and ulna, followed by application of External Skeletal Fixations. At 18 weeks postoperatively, the radius was healed. An incongruency of the elbow joint and radial angular deformity was corrected.

Osteochondroma (OC) is a cartilage-capped exostosis. In horses, OC commonly develops on the caudal distal metaphysis of the radius (CDMR). The purpose of study was to describe the outcomes of arthroscopy for the treatment of OC on CDMR. Diagnosis was based on clinical signs (lameness and distention of carpal sheath), radiography (location and size of OC), and ultrasonography (location of OC, torn deep digital flexor tendon, fibrin, and effusion of carpal sheath). Arthroscopy was performed on 68 Thoroughbred horses with OC on CDMR. Sixty of the 68 cases showed deep digital flexor tendinitis as a result of sharp protuberances of the OC. All horses survived, and 62 of the 68 cases returned to athletic function (racing) after arthroscopy. The present study demonstrated that arthroscopy is useful for treating OC of CDMR in horses.
