Based on data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted by Korea Centers for Disease Control & Prevention (KCDC), this study analyzed the relationship between existence of the spouse, number of family members, and disease afflictions of the Korean elderly, and factors affecting their quality of life. The collected data were analyzed by Chi-square test, t-test and One-way Anova, using the SPSS / WIN 25. Our comparative analysis on the health status and quality of life revealed that individuals in the singles group had significantly more diseases than the married group. The singles group considered their health was subjectively poor, whereas the quality of life of the married group was higher. Analyzing the characteristics of chronic disease and activity restriction showed significantly higher prevalence of several diseases in the singles group. Besides, the singles group revealed significantly higher limitations of activity. Taken together, our results reveal a difference in the health status, quality of life, and the presence of chronic diseases in accordance to existence of the spouse, indicating that having a spouse increases the level of health and quality of life of the elderly.

An anterior cruciate ligament (ACL) reconstruction is one of the most frequent surgical procedures in the knee joint, but despite the better understanding of anatomy and biomechanics, surgical reconstruction procedures still fail to restore rotational stability in 7%-16% of patients. Hence, many studies have attempted to identify the factors for rotational laxity, including the anterolateral ligament (ALL), but still showed controversies. Descriptions of the ALL anatomy are also confused by overlapping nomenclature, but it is usually known as a distinctive fiber running in an anteroinferior and oblique direction from the lateral epicondyle of the femur to the proximal anterolateral tibia, between the fibular head and Gerdy's tubercle. The importance of the ALL as a secondary restraint in the knee has been emphasized for successful ACL reconstructions that can restore rotational stability, but there is still some controversy. Some studies reported that the ALL could be a restraint to the tibial rotation, but not to anterior tibial translation. On the other hand, some studies reported that the role of ALL in rotational stability would be limited as a secondary structure because it bears loads only beyond normal biomechanical motion. The diagnosis of an ALL injury can be performed by a physical examination, radiology examination, and magnetic resonance imaging, but it should be assessed using a multimodal approach. Recently, ALL was considered one of the anterolateral complex structures, as well as the Kaplan fiber in the iliotibial band. Many studies have introduced many indications and treatment options, but there is still some debate. The treatment methods are introduced mainly as ALL reconstructions or lateral extra-articular tenodesis, which can achieve additional benefit to the knee stability. Further studies will be needed on the indications and proper surgical methods of ALL treatment.

Object : The aim of the current study is to assess the results of segmental resection and replantation for primary malignant or aggressive tumors of the upper limb. Materials and Methods : From 1986 to 1994, ten patients who had primary malignant or aggressive tumors of the upper limb were managed with segmental resection and replantation method. The average duration of follow-up was 7 years and 7 months. Primary indication of this method is stage II B tumors which, because of their extend, could otherwise be adequately treated only by amputation. Three patients had chondrosarcoma, two had osteosarcoma, two had giant cell tumors with pathologic fracture, one had extensive chondroblastoma, one had Ewings sarcoma, and one had leiomyosarcoma. The location of the tumor was humerus in 6 patients, scapula in 3 patients, and soft tissue of forearm in 1 patient. Wide resection margins were achieved in 7 patients and marginal margin in three. Results : One patient died on 40 months after surgery due to systemic metastasis. Nine patients have remained disease free without local recurrence or metastasis. The average overall functional rating was 65% (43~90%) for ten patients on the last follow-up by the functional rating system of Enneking. The mean grasping power and pinching power of operative hand was 75%(28~95%) and 65%(43~90%) of the opposite hand, respectively. Complications associated with this surgical method included three wound dehiscences and one nerve injury that resolved with proper wound care and time. Conclusion : It was concluded that segmental resection and replantation might be used for partial limb salvage in selected cases for the treatment of primary malignant or aggressive tumors of the upper limb.

Slipped capital femoral epiphysis(SCFE) is a disorder in which there is a gradual or acute disruption through the capital physeal plate. The physiolysis is through a widened zone of hypertrophy, which is weakened due to altered chondrocytic maturation and endochondral ossification. The cause or causes of SCFE remain uncertain. The association of obesity and adolescent age with growth rate are predisposing factors. The possibility that most patients with subclinical hormonal abnormality were proved. The goal of treatment of slipped capital femoral epiphysis is to restore the function of the hip and delay the development of degenerative osteoarthrosis by prevention of additional displacement of the epiphysis. We report 10 patients(12hips) with SCFE who were treated by surgical means and followed along for more than one year, at Yeungnam University Hospital, from 1989 to 1996. There were six boys and four girls. The average age at operation was 11.8 years. Seven cases occurred in the left hip, one case in the right and 2 cases had bilateral involvement, five cases had a history of minor trauma on affected hip. Among hormonally studied six patients, panhypopituitarism patient was one case; decreased testosterone, two; decreased growth hormone, two; and decreased thyroid hormone, one. According to clinical stage, two cases were the acute type; five cases, acute on chronic type; and three cases, chronic type. On the radiological grades of slipping, mild slippage were nine hips; moderate, one; and severe, two. The eleven hips were treated by pin fixation in situ, and one, by cuneiform osteotomy. On the average follow-up of 2.6 years, ten hips were excellent or good functional results, two hips were failure.

Purpose : To evaluate if at the time of diagnosis of Legg-Calve-Perthes disease, MR imaging is superior to radiographs for identifying patients with a favorable long term prognosis as determined by maintenance of a spherical configuration of the femoral head epiphysis on follow-up radiographs. Materials and Methods : We retrospectively analyzed plain radiographs and MR images of 48 femoral heads in 41 patients with Legg-Calve-Perthes disease at time of diagnosis. Femoral head involvement was estimated on initial plain radiographs and MR images using the Catterall classification. Prognosis as determined by maximum femoral head deformity was determined on follow-up radiographs evaluated according to Stulberg classification. Results: Catterall classification of greater than 1 at MR imaging had 100% sensitivity (14/14) for detecting patients with a poor prognosis as indicated by deformity of the femoral head on follow-up radiographs (Stulberg class > 2). Initial radiographs had a lower sensitivity of 57% (8/14) for detecting patients with poor prognosis. Specificity for MR imaging was 21% (7/34) which was not significantly different from 32% (11/34) specificity for initial radiographs. Conclusion: Catterall group 1 at initial MR imaging indicates favorable prognosis for Legg-Calve-Perthes disease. Patients with more extensive involvement of the femoral head can have a good outcome, however they are at risk for loss of spherical configuration of the femoral head and subsequent osteoarthritis in adulthood. MR imaging may be superior to radiographs for identifying a subgroup of patients with favorable prognosis.

Purpose: To evaluate the end results between the surgical treatment with neo-adjuvant chemotherapy in Korea and non-invasive high intensity focused ultrasound (HIFU) technique in China for osteogenic sarcomas. Materials and Methods: The surgical treatment with neoadjuvant chemotherapy for total 67 cases (4 IIA, 58 IIB, and 5 III) in Korea since 1993 and the HIFU therapy for total 71 cases (57 II and 14 III) in China since 1997 was performed. In Korea, neo-adjuvant chemotherapy in 66 cases out of total 67 patients, but the adjuvant chemotherapy in only one case was done. On the contrary, in China, full chemotherapy for more than 9 times for 37 patients with stage II out of total 71 cases, but for less than 8 times of partial chemotherapy for 23 patients (stage II) and 14 patients (stage III) was done. The surgical treatment in total 67 Korean patients was done with wide resection and reconstruction for 56 patients, but wide resection without reconstruction for 5 patients and amputation for 6 patients. In china, total 71 patients was treated with average 1.5 times (1~4 times) of HIFU, and if there are some evidences of residual tumor after HIFU with following MRI, the second HIFU therapy was given 2~4 weeks later. After then, the bony defect was in no touch, keep bracing for long time expecting regeneration. All of them were followed for average 46 Mo (12~150 Mo) in Korea, but followed for average 22 Mo (9 years~8 months) in China. Results: The 5 year survival rate (stage II), was average 92.7% (IIA 100%, IIB 85.5%) in Korea series, and average 78.7% (full chemotherapy 91.8%, part chemotherapy 56.6%) in China series. The 3 year survival rate (stage III) was 20% in Korea and 7.1% in China. So, the final overall survival rate was 65.2% in Korea and 51.8% in China. The overall functional outcome score by ISOLS was 24.3 (81%) in Korea and 19.8 (73%) in China. There are 25.4% (17/67 cases) of complications in Korea and 31% (27 complications in 22 patients out of total 71 cases) in China after each treatment. Conclusions: The end results of Korea series which was treated with neoadjuvant chemo- and surgical methods are better than that of non-invasive thermal ablation in china. But we also believe the HIFU, as one of, was also effective to decrease the local recurrence and symptomatic releaf for stage II or even in III of osteogenic sarcomas.

We experienced the case of familiar hypercholesterolemia with multiple xanthomas which was treated by combined surgical and medical therapy. He was 26-year-old male patient of familiar hypercholesterolemia with multiple xanthomas in 22 sites on whole body, and was treated by 17 surgical excisions of the xanthomas and by medical therapy of the hypercholesterolemia. There was a normal healing process of the surgical wounds. Continual postoperative medical therapy of the hypercholesterolemia was done. There was no recurrence of the symptoms during more than 13 months of follow-up. But the serum level of the cholesterol was not lowered significantly, so we are treating him with drug therapy. Familial hypercholesterolemia is caused by a specific disorder of lipid metabolism, and is characterized by increased LDL cholesterol, tendon xanthomas, coronary disease associated with autosomal dominant transmission. Xanthomas usually appear in the second decade of life with familiar hypercholesterolemia which may have high risk for premature coronary atherosclerosis, which might be prevented with early diagnosis and medical treatment. So, orthopedic surgeons do not only excise the xanthomatosis surgically but also can diagnose the underlying hypercholesterolemia.

Purpose: We reviewed the outcome of treatment of ossifying fibroma involving long bones. Materials and methods: Eight patients who enrolled at our hospital for ossifying fibroma from 1994 to 1999 were selected for this study. Mean age was 7.9 years old. Five were male and three female. Seven involved tibia and one fibula. All cases were diagnosed by biopsy. The initial treatment was conservative and the followings were operative indications; (1) repeated fracture, (2) suddenly growing mass, (3) severe bowing deformity, (4) pseudoarthrosis. We assessed the recurrence by x-ray follow-up. Results: As initial treatment, curettage was performed in 2 patients, observation in 2 subperiosteal resection in one and extraperiosteal resection in 3 patients. Two patients who were observed and 3 patients who received extraperiosteal resection did not suffer recurrence. Two patients who received curettage and one patient who received subperiosteal resection had recurrence. The second treatment was performed in 3 patients. The one case of curettage received extraperiosteal resection. The other was in observation. The case of subperiosteal resection was in observation, too. There were no recurrence and aggravation at follow-up. Conclusion: Ossiying fibroma should to be treated by conservative method. If operation is indicated, extraperiosteal resection could reduce the recurrence.

Purpose: Distraction osteogenesis is considered to take favorable effect on the TMJ and be beneficial to prevent the relapse after the mandibular advancement of Class II malocclusion patient. This is the report with literature review on the mandibular advancement in the patients showing preoperative condylar resorption and who need larger amount of advancement. Patients and method: Distraction osteogenesis using intraoral device was performed for three mandibular hypoplasia patients (one male and two females). All patients were adult over 18 years old. The patients showed condylar bony resorption preoperatively. The distraction was performed intraorally with modified SSRO. After 7 days of latency period, activation was performed at the rate of 1.0 mm/day with twice turn. The devices were removed after 4-8 month consolidation period. Results: Total advancement of mandible was average 13 mm. One patient showed openbite immediately after removal of distraction device. It took long time to guide the openbite with elastics. The comparison between cephalometries immediately after device removal and postoperative six month revealed average 3.4 mm relapse. This means that mandibular advancement with distraction osteogenesis needs overcorrection and elastic rehabilitation even after enough consolidation periods. Conclusion: Larger amount of mandibular advancement could be achieved with distraction osteogenesis in severe mandibular hypoplasia with condylar resorption. However, some relapse was found during the follow-up period and the over correction is considered to be needed. The effect of distraction osteogenesis seems to be investigated with long-term follow-up.
