본 순천향대학교 의과대학 정형외과학 교실에서는 2명의 환자에서 발견된 대퇴골두 골괴사와 함께 발생한 양측 슬관절 골괴사를 경험하였기에 보고하는 바이다. 대퇴골두 골괴사가 있는 환자에서 슬관절 동통을 호소하는 경우 연관통 등으로 여겨 간과하기 쉬우며, 대개 고관절의 통증으로 체중부하 보행이 어려운 경우가 많아 통증이 약하게 나타나기도 하기 때문에 관심을 가지고 슬관절 골괴사를 동반하는지 여부를 판단하여야 할 것이다. Osteonecrosis of the knee associated with osteonecrosis of the femoral head was very rare and reported cases were quite rare. We have experienced two cases of osteonecrosis of both knees associated with osteonecrosis of the femoral head. One is a 44-year-old man who had avascular necrosis of the righ femoral head and osteonecrosis of both knees, femoral condyle and metaphysis of proximal tibia. Another case is a 39-year-old man who had osteonecrosis of both femoral head and osteonecrosis of the both knees, medial condyles of both tibias. They were treated with total hip replacement arthroplasty for avascular necrosis of the femoral head and conservatively for osteonecrosis of the knee. If a person complains of pain in hip and knee simultaneously, we should pay attention and rule out osteonecrosis of the knee.

Dislocation is one of the serious complications in total hip replacement arthroplasties. The purpose of this study is to evaluate the risk factors of dislocation, including age, sex, preoperative diagnosis and bilaterality, history of previous hip surgery, positioning of component, soft tissue tension, treatment after dislocation or redislocation. Authors reviewed 190 patients of total hip replacement arthroplasty, which were performed from Jan. 1990 to Dec. 1996. 15 cases developed dislocation after surgery. Incidence of dislocation was 7.89%(15 of 190 cases). Dislocation after revision was not happened(0 of 18 cases). Inclination of acetabular cup was average 37.5° (range: 31° - 43° ). Average anteversion of the acetabular component was 18.1" by Woo and Morrey method, 11.4° by Hassan method. They were normal range except 3 cases. Dislocation was not prevented even though inclination and anteversion of acetabular cup were within normal range. Soft tissue tension is determined by change of limb and femoral neck length. Average limb length difference was -0.2mm(range; -l0mm - +10mm) and average offset difference was +1.7mm(range;-4mm - +18mm). Revision must be accomplished as soon as possible when limb shortening happen by upward migration of the acetabular component. In conclusion, anteversion of acetabular cup may be most important factor in our cases, so cup position must be fixed in proper position during operation.

Fracture of the talus are relatively uncommon injury. when they occur, however. they we of major importance. because of the relatively heigh frequency of complications and long term disability. Complications such as non-union, avascular necrosis, traumatic arthritis are frequently developed as a late sequele in fracture or fracture-dislocation of the talus because of talar surface is covered mainly with articular catilage and poor blood supply. Authors have reviewed 19 cases of the talus fracture & fracture-dislocation surgically treated at Soonchunhyang University Kumi Hospital from Januarty l987 to October l995 with minimal 1 year follow up period. The result were as follows l. Of 19 cases, I 6 male and 3 female with their average age of 29.8 years. 2. The cause of injury were traffic accident(motor veiheicle accident)-l0/19 cases (53%), direct trauma-2/19 cases(11%), sport injury-I/l9 5%) and fall from height- 019 cases (32%) 3. The most common concomittant injury was the ipsilateral fracture of the tibiofibular (including medial malleolar fracture)-9/19 cases(47%) 4. According to the hawkins' classification. 5 cases in typeI. 8 cases in typeII, 5 cases in type III and I cases in type IV. 5. According to the Hawkins' therapeutic criteria. excellent results in 8 cases, good in 7 cases, fair in 3 cases but poor in I case. 6. Avascular necrosis was occured in 7 cues (37%) and ankle stiffness in 4 cases (21%) but nonunion was not observed.

After distal radius fracture, delayed rupture of extensor pollicis longus is rare. It is known that delayed rupture of extensor pollicis longus tendon result from undisplaced distal radius fracture. We have experienced a case of rupture of the extensor pollicis longus tendon after undisplaced distal radius fracture, and treated with palmaris longus tendon graft. the result were satisfactory without complications.

<P>OBJECTIVE: The purpose of this study is to propose an objective and simple method for assessing surgical outcomes of cleft nasal deformity using two-dimensional digital images. DESIGN: Five plastic surgeons evaluated slides of 20 normal and 65 repaired cleft nasal deformities using the full range of values from 0 to 100 with 10-point intervals. Five laypersons rated 12 parameters per image from the same data set using the developed assessment tool. Correlation coefficients between the parameter values and the surgeons' grades were obtained to find the best matches, and a regression equation was formulated using those. The reproducibility of the proposed method used by the laypersons was compared with that of the subjective grades made by the surgeons. RESULTS: The mean correlation coefficient among the evaluated grades by the five laypersons using the proposed method was higher (.90) than that for the subjectively determined grades from the five plastic surgeons (.80). The grade reproducibility of the patients by the laypersons (9.6%) was also better than that by the surgeons (14.6%). CONCLUSIONS: The proposed assessment tool, including the regression equation, allows laypersons as well as surgeons to perform simple, reproducible, quantitative, and objective assessments of the surgical outcomes for cleft nasal deformity using two-dimensional photographs.</P>

Silk fibroin scaffolds were examined as a biomaterial option for tissue-engineered cartilage-like tissue. In tissue engineering for cartilage repair using a scaffold, initial chondrocyte-material interactions are important for the following cell behaviors. In this study, the surface of nanofibrous silk fibroin (NSF) meshes was modified by a microwave-induced argon plasma treatment in order to improve the cytocompatibility of the meshes used as cartilaginous grafts. In addition, the effects of a plasma treatment on the cellular behavior of chondrocytes on NSF were examined. The plasma treatment resulted in an increase in the hydrophilicity of NSF meshes suggesting that the cytocompatibility of the mesh might be improved. Furthermore, the human articular chondrocytes showed higher viability on the surface-modified NSF meshes. These results suggest that the surface modification of NSF meshes by plasma can enhance the cellular behavior of chondrocytes and may be used in tissue engineering.
