Purpose : This paper studies characteristics, occurrence types, radiographs, MRI(magnetic resonance imaging), and histopathologic findings of femur neck fracture following avascular necrosis of the femoral head. Materials and Methods : The subjects of this study are femur neck fracture following avascular necrosis of the femoral head occurring in 7 cases of 7 Patients with osteonecrosis of femoral head among 130 cases of 68 patients who were treated at our hospital from March 2001 to March 2005, and analyzed though plain radiography finding, MRI, and histopathologic test. Results : All 7 cases were found of osteonecrosis of the bilateral femoral head, and most of avascular necrosis in parts of femoral neck fracture had invaded entire femoral head. Simple radiographic findings were 1 case of stage Ⅱ, 4 case of stage Ⅲ, and 2 cases of stage Ⅳ according to the Ficat and Alert classifications, MRI finding included 5 cases of class C, 2 cases of class D according to the Mitchell classification, and all cases found lesions of low signal intensity in T1W1, high signal intensity in T2W2, and other parts. The 1 case of histopathologic test developed femur neck fracture between the necrotic zone and the reparative zone. The form of femoral head fracture includes 5 case of type A, and 2 case of type B according to the Usui classification Conclusion : A spontaneous femur neck fracture can occur without any special exterior force between the necrotic zone and reparative zone in case invaded with wide range of osteonecrosis of the femoral head.

Purpose : The management of patella in total knee arthroplasty is still problematic. The purpose of this study was to evaluate the changes of clinical and radiological results after total knee arthroplasty without patellar resurfacing. Materials and Methods : We retrospective evaluated the nonresurfaced patella in 50 knees(65 patients) at an average of 77.5 months after total knee arthroplasty(Duracon^(®), Howmedica, Rutherford, NJ). Patients were diagnosed as osteoarthritis in 45 and rheumatoid arthritis in 3 and the others were osteonecrosis , and evaluated using the knee society knee score and functional knee score, modified patellar score. Results : The mean preoperative knee society knee score in osteoarthritis and rheumatoid arthritis were 58.2 and 36.7 points, and functional score were 35.8 and 34 points. The mean postoperative knee society knee score in osteoarthritis and rheumatoid arthritis were 95.5 and 93.2 points, and functional score were 75.2 and 83 points and the mean modified patellar score was 28.5 points, and 26 cases(52%) were excellent(30 35 points, 18 cases(36%) were good(25 29 points) and 6 cases(12%) were fair(20 24 points). There were no patella associated complications and in 8 cases(16%) of anterior knee pain which resolved with conservative treatment at latest follow up. Conclusion : Total knee arthroplasty with patelloplasty, without patellar resurfacing , provided satisfactory results without significant problems, and can avoid the complications (patellar dislocation and subluxation, fracture and component loosening, rupture of patellar and quadriceps tendon). But long term radiological and clinical follow up is recommended.

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.

This paper aims at providing a concrete plan to improve technical and vocational teacher education in the College of Industrial Education of Chungnam National University. It is intended to propose a practical four-year regular and short-term course. Also, the estimated required facilities is included in this study as well as their management. The main conclusions and recommendations are summarized as follows; 1) The numbers of students enrollment should be reduced to 220 students which is the approximate number of future demand. 2) In order to offer to the students a broader education and to cope with the increase/decrease in demand of technical and vocational teacher within a specific field, the 8 department existing at the present (Department of Architecture Engineering Education, Civil Eng. Educ., Metallurgical Eng. Educ., Mechanical Eng. .Educ., Electrical Eng. Educ., Electronic Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.) would be combined into 5 (Department of Construction Engineering Education, Mechanical Eng. Educ., Electrical Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.). 3) The short-term course program is recommened to provide additional training and education to those candidates who already have experience in technical fields to meet an occasional demand. 4) It is necessary to add the Teaching Profession Section in the administrative organization of the College.

Purpose: The purpose of this study was to evaluate the clinical effect of electrocautery on the reduction of pain in patellar non-resurfacing bilateral total knee arthroplasty. Materials and Methods: A total of 50 patients were enrolled into this study; all patients had undergone bilateral patellar non-resurfacing total knee arthoplasty at our hospital, between January 2007 to December 2008, The minimum follow-up period was 1 year, The electrocautery of the patellar rim was performed randomly on one side only. The clinical results were evaluated between the electrocautery group and the non-electrocautery group based on measures of anterior knee pain, range of motion, American Knee Society clinical rating score, Feller knee score, Western Ontario and McMaster Universities score, and radiographic analysis. Results: There were statistically significant differences between preoperative and postoperative status for all parameters. There were no statistically significant differences noted between the electrocautery group and the non electrocautery group for all parameters. Conclusions: Electrocautery of patellar rim is thought to be less effective in reducing anterior knee pain.

( Soo Jae Yim ),( Yong Bok Park ),( Junyoung Kim ),( Sin Hyung Park ) 대한고관절학회 2018 Hip and Pelvis Vol.30 No.3

Purpose: This study was performed to evaluate long-term clinical and radiologic outcomes of cemented total hip arthroplasty in patients with ankylosing spondylitis. Materials and Methods: A retrospective study of 12 patients (16 cases) diagnosed with ankylosing spondylitis undergoing total hip arthroplasty with cemented femoral stem from November 2002 to January 2006 with a minimum follow up of 10 years. Clinical outcomes were assessed using Harris Hip Scores and measures of pain and range of motion. Radiologic outcomes were assessed with serial plain X-ray. Fixation and stability of implant, enthesopathy of ischium and development of heterotopic ossification were also evaluated. Results: Mean Harris Hip Scores significantly improved from pre-operative levels (58 points; range, 39-81 points) to post-operative (92 points; range, 68-100 points). Mean flexion contracture levels decreased from preoperative (13°) to post-operative (5°), and mean post-operative range of motion improved 106°compared to preoperative levels. No newly developed osteolysis lesions or implant loosening were observed in last follow up Xrays. One heterotopic ossification and one greater trochanter fracture were observed. Greater trochanter fracture was treated conservatively, and was resulted in bony union. No patients underwent revisions. Conclusion: This study revealed positive long-term clinical and radiologic outcomes following total hip arthroplasty with cemented femoral stems in patients with ankylosing spondylitis patients.
