Objectives : The purpose of this study is to report the effect of acupotomy for patient with avascular necrosis(AVN) of femur head. Methods : Three patient who had been diagnosed as AVN participated in this study. The patient treated by acupotomy therapy. After the treatment, the patient was measured by visual analogue scale(VAS), Harris hip score and five likert scale Results : The patient informed the researcher of reduced pain and improved range of movement after the conduct of acupotomy therapy. The efficacy of acupotomy treatment was reaffirmed by the results of the VAS, physical examination (ROM, Patrcik sign), Harris hip score. Conclusions : Acupotomy therapy on AVN of femur head shows the efficacy in reducing pain and improving movement.

Thiemann's disease is a form of idiopathic avascular necrosis of the immature epiphyses of the phalanges of the fingers and toes. Few cases of Thiemann's disease have been reported because the disease is rare and difficult to diagnose. To the best of our knowledge, magnetic resonance imaging (MRI) findings of Thiemann's disease have not been reported. Here, we report a case of Thiemann's disease diagnosed by typical clinical symptoms and characteristic MRI findings before radiologic bony abnormalities were apparent.

The hip is a stable ball-and-socket joint. Bilateral anterior dislocations of the native hip joints account for fewer than 1% of all dislocations. We present a unique case of a bilateral anterior dislocation in a patient who presented to our institution within 6 hours of trauma. The dislocations were promptly reduced under propofol anesthesia in the operating room. The patient did not suffer a concurrent fracture. After the procedure, we performed regular X-ray examinations for 2 years to rule out the development of avascular necrosis of the head of the femur. The course of the patient was unremarkable.

The neck of the talus is its most vulnerable and fragile segment, because of narrow diameter, devoid of hyaline padding and honeycombed internally by vascular channels etc. Talar neck fractures comprise 50% of all major to the talus. The majority occurs as a result of high-energy injuries, such as motor vehicle accidents or fall from a height. Anatomically, talar surface is covered mainly with articular cartilage and blood supply to the talus is very poor. So, complications, such as non-union, avascular necrosis and post traumatic arthritis, are frequent. The authors reviewed fourteen cases of talar neck fractures treated in our clinics from Jan. 1992 to Mar. 1997, and average follow-up period was over 15 months. The results obtained were as follows; 1. Patients' average age was 31.2 years. 2. The most common cause was traffic accident(9/14, 64%), and hyperdorsiflexion injury of the ankle was common mechanism of the fractures. 3. According to the modified Hawkins classification, type I was four cases, type II was nine cases, type III was one case and type IV was no case. 4. Hawkins sign of subcortical radiolucency was found in 64% (9/14) of the fractures. 5. Avascular necrosis was occurred in 21% (3/14) of the fractures(in two cases of type II fractures, and in one of type III). 6. According to the Hawkins criteria, four cases in type I, five in type II were an excellent result. Two cases, one in type II and one in type III were good result, and two in type II were fair. One in type II was poor result.

The author observed the changes of vasculature of pre-and post-irradiation on DMBA induced rat tongue cancer. The study was performed by using vascular corrosion resin casting, and scanning electron microscopy. The results were as follows. 1. The capillaries runned parallely and formed bundles and, sometimes, plexus. The endothelial cells were arranged regularly and small pores were observed. 2. In irradiated normal tongue the capillaries were curved slightly and formed plexus on initial day of post-irradiation. On third day the capillaries and capillary pores were dilated and the endothelial cell arrangement was irregular. The effects of irradiation were gradually increased from initial to the 3rd day, though it was decreased after 7th day. 3. The vasculature of DMBA induced tongue cancer group were very irregular, and large avascular lesions were formed according to the cancer necrosis or tumor cell nest and the vasculature was narrowed and paralleled around the avascular lesion by compression of cancer cell nest. The vascular wall was roughened and dilated, forming club shaped or varix. 4. The vessels were curved and formed reticular network in irradiated DMBA induced tongue carinoma group. The free end of newly formed capillaries had regular width, and also irregular club shaped or aneurysmal dilatation were observed. The vascular structures were destroyed and vessels were fused in tumor necrosis lesion. The radiation effects were marked on the first and third day of irradiation and the effects were decreased after seventh day and showed capillary regeneration.

Kienböck 질환을 완관절의 월상골에 발생한 무혈성 괴사로 정의하고 있지만 원인과 자연경과, 적정한 치료 방법에 대해서는 정확하게 밝혀져 있지 않다. 교과서적으로는 병의 진행 단계를 나누고 단계에 따라 치료 방법을 제시하고 있지만 과연 원칙에 맞는 올바른 치료 방법인지에 대한 충분한 검증 없이 따르고 있는 것은 아닌가 하는 의문이 드는 것도 사실이다. 저자는 그동안 많은 Kienböck 질환을 진단하고 치료를 하면서 교과서에 기술된 내용 중에서 의문이 드는 부분이 많았으며, 자료 분석과 경험을 토대로 나름대로의 적정한 치료 접근을 정립하고자 하였다. 본 종설에서는 기존의 지식이 과연 정확한 근거를 바탕으로 한 것인지 검토해 보면서 합리적인 치료 방법에 대한 저자의 의견을 제시해 보고자 한다.

Background: Risk factors for bone avascular necrosis (AVN), a common late complication after kidney transplantation (KT), are not well known. Methods: Patients that underwent living-donor KT at Asan Medical Center between January 2009 and July 2016 were included in this retrospective study to determine the incidence and risk factors for AVN after KT. Results: Among 1,570 patients that underwent living-donor KT, 33 (2.1%) developed AVN during a mean follow-up of 49.8±25.0 months. Additionally, AVN was diagnosed at a mean of 13.9±6.6 months after KT. The mean cumulative corticosteroid dose during the last follow-up in patients without AVN (9,108±3,400 mg) was higher than that that in patients with AVN (4,483±1,114 mg) until AVN development (P<0.01). More patients among those with AVN (n=4, 12.1%) underwent steroid pulse treatment because of biopsy-proven rejections during the first 6 months after KT than patients without AVN (n=68, 4.4%; P=0.04). Female (hazard ratio [HR], 2.29; P=0.04) and steroid pulse treatment during the first 6 months (HR, 2.31; P=0.02) were significant AVN risk factors as revealed by the Cox proportional multivariate analysis. However, no significant differences in rejection-free graft survival rates were observed between the two groups (P=0.67). Conclusions: Steroid pulse treatment within 6 months of KT and being female were independent risk factors for AVN development.
