Osteochondroma is the most common benign bone tumor which commonly occurs in the metaphysis of the long bones such as proximal humerus, tibia, and distal femur. It is rarely found in bones of the foot. Although they are benign lesions, when they occur in the foot, they are typically identified earlier than other regions because of the low proliferation of subcutaneous tissue in the region and may cause symptoms. We experienced a rare case of osteochondroma in a 60-year-old male which cause pain and swelling of the fourth toe.

Metatarsal head and neck fractures are injuries that often result from a direct blow of a heavy objects to the metatarsal head. The head is often impacted or displaced to the plantar aspect that if not treated may cause malunion which later induces painful plantar calluses. If the fracture fragment is large enough, closed reduction may be successfully performed, but when the fragment is small or closed reduction is unsuccessful, open reduction is needed. We present our reduction and fixation technique for the metatarsal head and neck fractures using antegrade intramedullary Kirschner wire (K-wire) without opening the fracture site or infringing the metatarsophalangeal (MTP) joint which allows immediate motion of the joint and partial weight bearing in a stiff soled shoe.

Synovial chondromatosis is an uncommon disorder characterized by cartilaginous proliferation in the synovium. The cartilaginous nodules occur in the synovial membrane of a joint, bursa, or tendon sheath. It frequents large joints including knee, hip, and elbow. Synovial chondromatosis originating from the first metatarsal is extremely rare. We report a case of 37-year-old man with synovial chondromatosis of the first metatarsal.

Ossification of the Achilles tendon is a rare condition that is characterized by the presence of an ossific mass contained within the substance of the tendon. The ossified mass is usually asymptomatic but when it grows large and painful, it deteriorates the function of Achilles tendon. We report a case of ossification of the Achilles tendon, which was successfully treated by removal of the ossific mass and proximal flexor hallucis longus (FHL) tendon transfer.

김형년,서일우,박용욱,Kim, Hyong-Nyun,Suh, Il-Woo,Park, Yong-Wook 대한족부족관절학회 2009 대한족부족관절학회지 Vol.13 No.2

Purpose: The purpose of this study was to evaluate the clinical results of the old Achilles tendon rupture treated with modified flexor hallucis longus (FHL) tendon transfer. Materials and Methods: Seventeen patients with old Achilles tendon rupture treated with modified FHL tendon transfer between March 2004 and February 2008 were enrolled in this study. Technically FHL was pass through the distal portion of the ruptured tendon instead of the drilled hole made on the calcaneus. The mean age of the patients was 37 years (range, 22~67 years), mean follow-up period was 28 months (range, 12~30 months). Patients' subjective satisfaction, calf circumferential diameter, range of motion of ankle and AOFAS ankle-hind foot score and Arner-Lidholm score was evaluated. Results: The average gap between the ruptured tendon was 52 mm (range, 47~56 mm). The AOFAS score improved from 47 pre-operatively to 91 points at the last follow-up. Sixteen patients were satisfied with the result free from discomfort, a patient had mild discomfort who had DM. fourteen patients had decreased range of motion less than 5 degrees while 2 patients had more than 7 degrees decrease compared to the intact side but had no discomfort in daily activities. Nine patients had less than 1 cm calf circumferential diameter difference and 7 patients had 1 to 3 cm diameter difference compared to the intact side. One who had more than 3 cm diameter difference had deteriorated muscle strength. Conclusion: Modified FHL tendon transfer can be a useful technique for the treatment of old Achilles tendon rupture when the gap is with large gap placed too proximal.

Purpose: We try to evaluate the clinical results of the acute Achilles tendon rupture treated with Krackow suture technique. Materials and Methods: We reviewed 27 patients with acute Achilles tendon rupture treated between October 2005 and September 2007. There were 26 complete ruptures and 1 incomplete rupture. All were ruptured at tendinous area. There were 21 men and 6 women, and mean age was 38 years. We repaired ruptured Achilles tendon with Krackow suture technique. The results were evaluated with Arner-Lindholm scale for patients' satisfaction, strength of calf muscle power, calf circumference, and ankle motion. The average follow-up was 29 months. Results: The patients' subjective clinical results was excellent in 25 cases and good in 2 cases. There were 15 cases of less than 1 cm, 6 cases of 1${\sim}$3 cm, and 1 case of more than 3 cm in the calf circumference difference between the normal and affected leg. There were 20 cases of less than 5 degrees, and 2 cases of more 5 degrees in the difference of range of motion between the normal and affected ankle. We had an experience of postoperative deep infection in one diabetic patient. Conclusion: We had a good clinical result for acute Achilles tendon rupture treated with Krackow suture method. So we recommand Krackow suture technique for acute Achilles tendon rupture.

Calcific tendinitis usually occurs in the supraspinatus tendon of the shoulder. Calcific tendinitis of the peroneus longus tendon has not been reported on the Korean journals. Differential diagnosis includes bipartitis os peroneum, os peroneum fracture and peroneal tendinitis. We report a rare case of calcific tendinitis of the peroneus longus tendon which responded well with the conservative treatment.

Purpose: This study was performed to compare the anatomic differences of the fibular incisura of the tibia between ankle fractures with and without syndesmotic injuries. Materials and Methods: 42 patients were involved in this study: Group I was composed with 14 cases of ankle fractures with syndesmotic injuries; Group II was composed with 14 cases of ankle fractures without syndesmotic injuries; Group III was composed with 14 cases of volunteers. The height averaged 170.1 cm (range, $159{\sim}181$ cm) in group I, 168.9 cm (range, $156{\sim}184$ cm) in group II, and 170.4 cm (range, $161{\sim}77$ cm) in group III. The mean height did not show a statistically significant difference between groups (p>0.05). All patients were taken axial computed tomography. The length of anterior and posterior facets, angle between anterior and posterior facet, and depth of the fibular incisura of the tibia were measured. Results: The mean length of the anterior facet was 11.5 mm (range, $9.2{\sim}15.7$ mm) in group I, 12.2 mm (range, $7.3{\sim}17.0$ mm) in group II, and 10.3 mm (range, $8.7{\sim}14.0$ mm) in group III (p>0.05). The mean length of the posterior facet was 12.3 mm (range, $9.0{\sim}14.5$ mm) in group I, 11.0 mm (range, $7.3{\sim}16.2$ mm) in group II, and 13.0 mm (range, $9.2{\sim}15.9$ mm) in group III (p>0.05). The mean angle between anterior and posterior facet was 139.1 degrees (range, $125.5{\sim}154.0$ degrees) in group I, 144.2 degrees (range, $134.7{\sim}152.6$ degrees) in group II, and 131.5 degrees (range, $117.6{\sim}144.4$ degrees) in group III (p<0.05). The mean depth of the fibular incisura of the tibia was 4.1 mm (range, $3.2{\sim}15.8$ mm) in group I, 4.6 mm (range, $3.1{\sim}7.1$ mm) in group II, and 3.1 mm (range, $1.5{\sim}4.0$ mm) in group III (p<0.05). Conclusion: There are some statistical differences of angle between anterior and posterior facet and depth of the fibular incisura of the tibia between ankle fractures with and without syndesmotic injuries.

Freiberg disease is a osteochondrosis of the lesser metatarsal heads. Various surgical treatment have been recommanded including joint debridement and metatarsal head reshaping, metatarsal dorsal wedge osteotomy, metatarsal head excision and joint arthroplasty. Autogenous osteochondral graft for the treatment of Freiberg disease is an effective restorative procedure that provides early range of motion exercise, weight bearing, and reduces other morbidity. We report a case of late stage Freiberg disease treated with arthrotomy, removal of loose body and autogenous osteochondral graft.

사이버공간에서의 공공디자인 개념 확립을 위한 연구

김형년(Kim Hyungnyun) 한국디지털디자인학회 2009 디지털디자인학연구 Vol.9 No.1

인터넷은 기존의 개념과는 다른 사이버라는 새로운 삶의 공간을 만들었다. 일반적으로 사이버공간은 컴퓨터 네트워크가 창출하는 공간적 은유를 의미하며 구체적으로는 다른 사람들과 공유하고 집단적으로 구성되는 네트워크상의 공공적인 가상사회를 의미한다. 보통의 경우 사이버공간을 가상이라는 의미로 표현하고 있지만 막연히 추상적인 사회는 아니다. 사이버공간에는 나름대로 행위의 주체와 양식 제도와 규범이 존재하고 있다. 따라서 가상 사 회로서 사이버공간은 실제 사회와 전적으로 격리되어 있는 것이 아니다. 또한 사이버공간은 누구든 자유롭게 드나들 수 있는 공평한 가상공간으로서 자신을 드러내지 않고 익명성을 바탕으로 현실의 공간보다 더 자유롭게 대화하고 참여하고 비판 할 수 있다. 이러한 개방성은 역으로 법적 도덕적 규범으로 판단하기 어려운 새로운 형태의 사회 병리학적 문제점들을 야기하고 있다. 이러한 문제점을 해결하기 위해 현재 다양한 노력이 정치 경제 사회 문화의 다방면에 걸쳐 이루어지고 있다. 본 논문에서는 사이버공간의 이러한 문제점을 공공 공간에서의 공공 디자인의 역할과 의미를 통하여 극복할 수 있을 것이라는 가정 하에 실제 공공 공간과 사이버공간과의 특징과 상호 연관성을 분석하고 이를 바탕으로 공공디자인의 기능적 목표인 공적 사회성을 적용하여 사이버공간에의 공공디자인 개념 도입의 필요성을 제시하고자 한다. Internet have made a new life space cyber space which is completely different from the pre-existing notions of life space. In general cyber space means a spatial metaphor created by the computer network which is considered in concrete as a public community shared with other people and composed by groups within the network. Normally it is said that cyber space is equivalent to the idea of virtual space however it is not a hazily abstract community. Cyber space has their own style of subject of acts forms regulations and rules. In fact cyber space as a virtual community is not actually separated from the real society. Furthermore since it is unbiased space where every body can feel free to join in along with the total anonymity given by the system users are not obligated to reveal themselves it makes users to be more comfortable participating in the cyber space making a conversation with other users and criticizing about the problems they share. However this open characteristic of cyber space is provoking new sorts of social pathological problems which hardly can be judged by the existing law and ethical standard. Therefor a great amount of effort is undertaken in various sectors: from the political to the financial to the public to the cultural sector. In this thesis I would like to discuss about the necessity of applying the public design in cyber space by analyzing the features of actual public space and cyber space and also the interrelation between those two spaces under the assumption that the problems now occurring in cyber space can be solved along with the aid of establishment of clear roles and meanings of the public design.
