Recent advances in imaging techniques, surgery and combination anti-cancer chemotherapy have brought high survival rates in osteosarcoma. To investigate the survival rate, local recurrence and complications in treatment, we analysed 25 osteosarcoma cases who had been treated with preoperative neo-adjuvant chemotherapy, surgery and post operative chemotherapy at Department of Orthopedic Surgery, Catholic University. From May 1988 to April 1995, 42 cases of stage IIB osteosarcoma were admitted in Department of Orthopedic Surgery. Among them, 17 cases who didn't follow our treatment guidance were excluded in this study. The average age were 19 years. There were 21 males and 4 females. The involved sites were 4 humerus, 10 femur, 10 tibia and 1 talus. Eleven cases had received intraarterial cisplatin and intravenous adriamycin chemotherapy, and 7 T-10 protocol and 7 intravenous ifosfamide, ADR, methotrexate, cisplatin. Twenty-three cases were treated with limb salvage surgery, and 2 amputation. The average follow-up was 35 months(3~82). There were 14 cases of continuous disease free, 9 cases of died of disease, 1 case of alive with disease, and 1 case of no evidence of disease at final follow-up. There were three cases of local recurrence at 6,8 and 12 months after operation. The estimated Kaplan-Meier's 5 year survival rates for all, ADR-cisplatin group, T-10 protocol group, and ifosfamide regimen group were 6%, 73%, 44% and 72%, respectively.

Physiotherapyists frequently use manipulative therapy technique to treat dysfunctionand pain resulting from ankle sprain. Despite the high prevalence of lateral ankle ligament injuries, few studies are available indicating any physical associations with the development of lateral ankle ligament injuries, or information of treatment for lateral ankle ligament injuries. To investigate the effect of passive joint mobilization, the anteroposterior glide on the talus, on increasing weight-bearing dorsiflexion, single support time and VAS. Sixty lateral ankle ligament injuries (grade I and grade II) aged between 17 and 27 years (mean age 21) were recruited. Subjects were randomly assigned to 1 of 2 treatment groups. The control group received a protocol of rest, ice, compression, and elevation (RICE) and massage. The experimental group received the anteroposterior mobilization, using a force that avoided incurring any increase in pain, in addition to the RICE protocol. Subjects in both groups were treated every second day for a maximum of 2 weeks or until the discharge criteria were met, and all subjects were given a home program of continued RICE application. Outcomes were measured after each treatment. The results showed that the experimental group than the control group. Weight-bearing dorsiflexion (F=7.640, P<0.05), single support time (F=85.532, P<0.05) and VAS (F=10.610, P<0.050). Between-groups differences were observed as; experimental group is increased weight-bearing dorsiflexion, single support time and reduced VAS.

Purpose: To evaluate clinical features of ankle lesions, associated with anterior soft tissue impingement. Materials and Methods: We retrospectively reviewed 21 patients who had chronic anterior ankle pain as initial symptom and associated ankle lesions with anterior soft tissue impingement. Based on preoperative radiologic findings, physical examination intra-operative findings, appropriate procedures were done for lesions by either arthroscopic or minimal open procedure or combined. Clinical evaluation was done using American Orthopedic Foot and Ankle Society, ankle-hind foot score (AOFAS score) and visual analog scale (VAS) on last follow up. Results: Associated lesion(s) to anterior soft tissue impingement of the ankle were 16 cases of osteochondral lesion of talus, 14 cases of bony impingement, 6 cases of ankle lateral instability, 5 cases of loose body, 4 cases of os subfibulare. AOFAS score was $58.9\;{\pm}\;5.1$ preoperatively and $74\;{\pm}\;9.1$ on last follow up. Clinical satisfaction score using VAS showed excellent in 3 cases, good in 11, fair in 3, poor in 4. Conclusion: The patients who had anterior soft tissue impingement would have various associated lesions on their ankle. In such cases, preoperative counseling for variety of postoperative results would be needed.

Osteomas are most often located in the femur, tibia, humerus, spine, and talus. They are rare in the skull. Osteomas in the head and neck regions are benign bone neoplasms usually found in the frontoethmoid area. The developmental theory postulates that osteomas develop at the sites of fusion of tissues different embryological origin such as occur at the junction of the embryonic cartilaginous frontal and ethmoid bones. Trauma and infection have also been implicated as causative factors, but many patients with osteoma deny any preceding history of these. Osteomas are usually produce symptoms primary to cosmetic problems and secondary to pressure on adjacent structures. The objects of this study are from a 5-year period of April of 2002 to April of 2007, consisting of 48 male patients and 52 female. There were 33 cases of frontal bone osteomas, 5 cases of madibular bone osteomas, 5 cases of occipital bone osteomas, 6 cases of symptomatic paranasal sinus osteomas, 48 cases of asymptomatic paranasal sinus osteomas, and 3 cases of mastoid osteomas. We reviewed medical records of patients to find out their presentations, diagnostic considerations, therapeutic options, and outcomes. Patients were followed up six months postoperatively on the average. The authors experienced 48 cases of osteoma in the head and neck lesion, which were removed via direct approach or endoscopic approach. The 100 cases who came to the hospital with or without symptoms after diagnosis healed completely without sequelae. During the follow-up periods, excellent functional and cosmetic results were observed with an inconspicuous scar. There was no specific complications related to this procedure. Results of surgery in most cases were satisfied. We discussed the surgical procedure and the characteristics of the osteomas, and we report several cases with the review of literatures.

In most mountainous parts of the temperate zone of Japan along the Pacific Ocean, some climatic climax forests, whose main dominant species is Fagus crenate, F. japonica or Quercus mongolica var. grosseserrata, are distributed. In the riparian regions of the zone, however, there appear summer green forests composed of the different species from the climatic climax forests. Climate plays an important role in determining the overall distribution of vegetation, but some environmental factors, i.e., topography, soil type, soil moisture content, etc. have a great influence on vegetation formation. Riparian forests seem to be controlled by various geomorphologic disturbances, such as landslide, soil erosion and accumulation. The study aims to present the relationships among vegetation, soils and landforms in the process of determining riparian forests dominated by Fraxinus platypoda and Pterocarya rhoifolia establishment in the mountainous region of central Japan. The study area extends an area of 302 ha with a range of elevation between 925 m and 1,681 m at the Chichibu mountains. The landforms were corditied at sampling grids (25 $\times$ 25 m, n = 4,843) using a hierarchical system, and a brief description of the forest soil classification was also given. The mutual relationship analysis indicated that forest soils and landforms play a significant role in determining the geomorphological process of riparian forest, and shaping the ultimate pattern of vegetation. At the study area, riparian forests were mainly found on the $B_E$ forest soil type and steep slopes ( > 30$^{\circ}$) at convex slopes along the streams. On the other hand, the direction of slopes did not have a significant impact on the establishment of the riparian forests. A mosaic of patchy distribution of those riparian forests on the slightly wetter $B_E$ forest soil type was one of the characteristic features of the study area. This particular soil which contained large talus gravels was found on the land formed by erosion and deposition of landslide.
