This paper describes the case of a 50-year-old female with a Class II malocclusion who presented with severe bimaxillary protrusion and generalized alveolar bone loss due to adult periodontitis. The treatment plan consisted of extracting both upper and lower first premolars and periodontal treatment. Anterior segmental osteotomy(ASO) of the mandible and upper anterior segment retraction using compression osteogenesis after peri-segmental corticotomy(Speedy orthodontics) was performed. Correct overbite and overjet, facial balance, and improvement of lip protrusion were obtained. However, a slight root resorption tendency was observed on the lower anterior dentition. The active treatment period was 9 months and the results were stable for 27 months after debonding. This new type of treatment mechanics can be an effective alternative to orthognathic surgery.

8개월령의 체중이 40.4kg인 로트와일러 수컷 어린개와 9개월령의 체중 34.6kg인 골 든 레트리버 수컷 어린개가 각각 2주령과 1개월령부터 파행 및 통증을 주중으로 머독대학 동물 병원에 내원 하였다. 내원 했을 때 호흡과 심박수 및 체온은 정상이었다. 일반 보행 및 신경검사 와 방사선 사진을 촬영하여 확인한 결과 양측 고관절 이형성(Hip displasia)과 퇴행성 관절질환 (Degenerative joint disease)을 확인 할 수 있었으며, 그 증상의 정도는 우측에 비하여 좌측이 더 심하게 나타냈다. 외과적 치료는 Slocum과 Devine에 의한 3중 고관절 절단술(Triple pelvic osteotomy)를 실시하였으며 특별한 외부 고정은 하지 않았다. 수술 후 5개월 동안 지켜본 결과 증 상은 매우 좋아졌으며 골반골의 완벽한 고정 유지에 따른 교정된 고관절을 확인 할 수 있었다.

1980년 일리자로프가 하지에서의 골 신장술을 발표한 이래 수많은 외과 의사들이 임상연구와 발표를 거듭해 현재의 골 신장술을 이루었다. 악골에서 골 신장술의 적용은 1992년 8명의 악골 기형 환아에게 하악지 신장술을 적용한 맥카시의 발표를 기점으로 시작되었다. 골 신장술의 장점은 부족한 골조직과 함께 주변 연조직을 신장시키는 것으로 복합적 조직 결손을 보이는 선천성 악골 기형 환자들에게 특히 유리하게 적용시킬 수 있다. 반안모 왜소증은 안면 반측의 상/하악골 및 악관절, 연조직의 저성장 및 결손을 보이는 비교적 흔한 악골 기형이다. 하악지 신장술의 활발한 연구로 이를 이용한 악관절 증상과 안면 비대칭의 해소가 일차적 치료기법으로 선택되고 있다. 연구자들은 악관절 증상과 안면 비대칭을 주소로 내원한 성인 반안모 왜소증 환자에게 상악 및 하악의 동시 골 신장술을 적용하여 만족할 만한 결과를 얻었기에 이를 발표한다. 상악골의 Le Fort 제1형 골 절단술과 이환측의 하악지 시상분할 골절단술 후에 Molina distractor를 하악지에 적용하고 악간 고정을 통해 동시 신장을 꾀하였다. 수술 기법 및 평가 기법에 대하여 논의하였다.

Purpose: The clinical outcomes were investigated to determine if arthroscopic management is a useful method for 19 hips with iliopsoas tendon impingement (IPI) after total hip arthroplasty (THA). Materials and Methods: Eighteen patients (19 hips), who complained of groin pain and flexion pain that persisted after THA from September 2013 to December 2019, were the subjects of this investigation. The mean time to manifestation after THA was four months (range, 1-9 months) in patients of an average age of 60 years (range, 50-69 years). Thirteen out of 18 patients underwent THA using the direct anterior approach and five by the lateral approach. IPI was diagnosed by the medical history, physical examination, blood test, radiographic examination using X-ray and computed tomography, and topical injection therapy. All patients underwent arthroscopic treatment and a dynamic arthroscopic physical examination after exposure to the iliopsoas tendon revealed impingement. Tenotomy was then performed on the muscle portion through the total tendon portion. Symptoms and pain levels of preoperative, postoperative and follow-up period were investigated and compared. Results: The Western Ontario and McMaster Universities Osteoarthritis Index score decreased from an average of 58.4 (range, 40-88) before surgery to an average of 35.0 (range, 15-76) after surgery. Similarly, the visual analogue scale decreased from an average of 4.0 (range, 2-6) before surgery to an average of 1.4 (range, 0-4) after surgery. Sixteen patients (88.9%) showed pain relief and improvement in the straight leg raise test, and two patients showed postoperative muscle weakness and sustained pain. In the follow-up period, muscle weakness improved. One patient underwent arthroscopic iliopsoas tenotomy at the lesser trochanteric level but the symptoms persisted. The clinical symptoms were improved after one more tenotomy at the joint level. Conclusion: Arthroscopic iliopsoas tenotomy performed in patients with IPI after THA showed good clinical results.

A 75-year-old male patient without any significant medical and habitual risk factors for acute atherosclerosis obliterans except for hypertension was diagnosed with coronavirus disease 2019 with dyspnea, coughing, and mild fever. After a week of hospitalization, he complained of right foot pain and numbness. The symptoms were aggravated during the next week, resulting in a complete toe color change and loss of dorsalis artery pulse. Enhanced 3-dimensional computed tomography angiography revealed thrombus formation in the right common iliac artery and a loss of blood flow below the popliteal artery on both sides. The patient underwent percutaneous balloon angioplasty with stent insertion followed by medical therapy for anticoagulation. The clinical symptoms immediately were improved after the intervention, but the great toe necrosis was not recovered. Finally, amputation of the great toe was performed.

Background: This study was performed to investigate the outcomes of vascular operations that were done in patients with atheroscerosis obliterans (ASO) of lower limb. Material and Method: Forty patients underwent vascular operations from December 1996 to June 2004. The patient's records were analyzed retrospectively. Mean age was $66{\pm}8$ years (range, $47{\sim}81$ years). Gender ratio was 37:3 (male:female). Result: The operations were done on 50 lower limbs of 40 patients. The names of operations were femoropopliteal bypass in 12 patients (30%), femorofemoral bypass in 12 (30%), femorofemoral bypass and femoropopliteal bypass in five (12.5%), aorta-lower limb artery bypass in five (12.5%), axillofemoral bypass in two (5%), iliopopliteal bypass in two (5%), and endarterectomy in two (5%). All bypass surgeries were done with prosthetic conduits. Mean follow up period was $33.2{\pm}23.2$ months (range, $3.8{\sim}90.2$ months). The cumulative patency rates of 1 and 5 years were 75.5 and 58.7% respectively. In six patients, amputation of the lower limb was done. In eight patients, 12 complications occurred. After the first operation, 10 patients underwent reoperations. Conclusion: Our lower limb arterial bypass surgery revealed acceptable patency rate, but not a few patients required reoperations. An epochal treatment modality that can inhibit the progress of ASO and improve long term patency should be established.

Purpose : In patients having malignant and aggressive bone tumors around knee joint requiring amputation, segmental resection and rotationplasty were performed and the clinical results were analyzed. Materials and Methods : Twenty-six patients underwent segmental resection and rotationplasty between February 1988 and June 1994, because limb salvage with tumor prosthesis after removal of tumor was impossible. The mean follow-up of malignant tumors was 57(6~120) months and the average age of patients was 21.4(5~37) years old. Out of 26 patients, there were 18 osteosarcoma(${\geq}$stage IIB), 2 synovial sarcoma, and 6 giant cell tumor. Results : Clinical results were evaluated by the Shriner's rating system. Four patients were excluded due to death or amputation and remaining 22 patients were included for assessment. Eighteen patients had excellent result, 3 good, and 1 fair. Range of motion of ankle joint was -11(dorsiflexion)~80(plantarflexion) degrees and daily walking activity with prosthesis was possible. Local recurrence developed in 2 patients and distant metastasis in 10. Early complications had 3 thrombosis and 1 sepsis, and late complications had 6 nonunion, 2 malrotation and 1 stiffness of ankle joint. Conclusion : Rotationplasty which is functionally excellent may serve as an effective partial limb salvage procedure, especially in patients less than 10 years old that lower extremity discrepancy or loosening tumor prosthesis due to enlargement of medullary cavity are anticipated or amputation is inevitable for wide resection margin.
