인공 고관절 전치환술 후 발생한 하 둔 동맥의 가성 동맥류 -증례 보고-
정영율 ( Young Yool Chung ),정현균 ( Heun Guyn Jung ),김기수 ( Ki Soo Kim ) 대한고관절학회 2005 Hip and Pelvis Vol.17 No.4
Pseudoaneurysm after total hip arthroplasty (THA) is a rare and unusual complication. Pseudoaneurysm after THA results from direct vascular injury, indirect vascular injury including retraction, stretching and during acetabular screw fixation. We report a case of pseudoaneurysm of inferior gluteal artery after THA, which was successfully treated by percutaneous transcatheter embolization.

Sirus® 골수정을 이용한 대퇴골 골절의 치료: 삽입점에 따른 합병증 비교
정영율 ( Young Yool Chung ),최동혁 ( Dong Hyuk Choi ),윤대현 ( Dae Hyun Yoon ),이정호 ( Jung Ho Lee ),박지훈 ( Ji Hun Park ) 대한골절학회 2015 대한골절학회지 Vol.28 No.2
Purpose: The purpose of this study is to analyze the clinical results of fixation using Sirus® nail in patients with femoral subtrochanteric and shaft fracture and the difference in the frequency of complications according to the entry portal. Materials and Methods: From July 2006 to August 2013, at least 1-year clinical follow-up, we retrospectively analyzed 36 cases with femoral subtrochanteric (15 cases) and shaft fracture (21 cases) who underwent surgery using Sirus® nail. We reviewed the records of operation time, intra-operative amounts of bleeding and complications. At last follow-up, we reviewed clinical results by Ray-Sanders criteria and analyzed the periods of bone union on the radiograph. We also measured changing of the femoral neck-shaft angle in the subtrochanteric fractures and angulation in the shaft fractures, respectively. Considering anatomical variation of the trochanter and fracture position of subtrochanteric and femoral shaft, entry points were divided into subgroups, and the clinical results were compared. Results: The mean Ray-Sanders score was 27.4, 27 cases (75.0%) were good or excellent. The mean periods of bone union was 21.1 weeks in 31 cases. The mean neck-shaft angles were 135.7o preoperatively, 130.2o postoperatively. The mean angulation of the femur was 24.4o preoperatively, 2.4o postoperatively in patients of femoral shaft fractures. Despite no statistical significance, greater trochanter tip entry point and lateral entry point had a higher rate of frequency than medial entry point, with respect to the occurrence of iatrogenic fracture and malalignment. Conclusion: Using Sirus® nail for femoral subtrochanteric and shaft fractures showed good clinical and radiographic results and a high rate of union. Medial entry point yielded slightly better results in the occurrence of iatrogenic fracture and malalignment, compared to greater trochanter tip entry point and lateral entry point.

Purpose: The purpose of our study is to examine early radiographic findings and clinical signs of failure of the microstructure surface HA-coated acetabular cup. Material and methods: This study included 41 revisions of 204 THA with hydroxyapatite-coated acetabular cup from April 1992 to November 1996. Radiolucent line around cups, change in the cup angle and osteolysis were evaluated in serial radiographs. Acetabular cup was defined as loosening if any movement occurred at the bone and socket interface by manual rotation and extension force intraoperatively or migration of more than 2 mm and change of the cup angle by more than 5 degrees in radiographs. Results: The radiolucent line was observed in 12 of the 41 hips at an average of 55.4 months postoperatively and was most commonly located in zone III. All of the 12 hips showing radiolucent lines were classified as loosening by radiographically in 8 cases and intraoperatively in 4 cases. Radiographic loosening occurred at an average of 28.8 months after the appearance of a radiolucent line. Inguinal pain was noted in 18 of the 19 cases revised for acetabular cup loosening. Conclusion: The most important radiographic finding for the early diagnosis of loosening was progressive radiolucent lines, which occurred most frequently in zone 3.

A dislocation after total hip arthroplasty is a serious complication that is related to the component position and poor patient compliance. Therefore, the attendants and surgeons need to be aware of the risk factors for dislocations and take steps to prevent them. In addition, the surgeon should insert the components within the safe zone. The patients should also be informed of possibility of dislocations after total hip arthroplasty. Dislocations can be treated conservatively but a recurrent dislocation requires surgery. The causes of recurrent dislocations must be evaluated before surgery to achieve a high success rate.

무시멘트형 인공 고관절 전치환술 후 발생한 뇌 경색 -증례 보고-
기성찬 ( Sung Chang Ki ),정영율 ( Young Yool Chung ),김관우 ( Gwan Woo Kim ) 대한고관절학회 2009 Hip and Pelvis Vol.21 No.4
A seventy-two year old male patient who had degenerative osteoarthritis due to acetabular dysplasia on the left hip joint was operated upon for cementless total hip arthroplasty. Sudden left hemiparesis developed on the day after the operation, so we immediately carried out brain computed tomography and magnetic resonance imaging. This showed multiple occlusions of the brain vessels at the right cerebral hemisphere. There was no arterial-venous shunt on the preoperative echocardiogram, yet the ultrasonogram of the right carotid artery showed over 70% postoperative stenosis. There was no evidence of pulmonary embolism on the chest computed tomography. We report here on a case of cerebral infarction that was caused by multiple microemboli after cementless total hip arthroplasty and we review the related medical literature.

Introduction: We wanted to evaluate the efficacy of bipolar hemiarthroplasty using Berger`s two-incision surgical technique for patients with muscular weakness around the hip joint and/or a high risk of dislocation. Materials and Methods: We performed bipolar hemiarthroplasty for 15 femoral neck fractures using Berger`s two-incision technique between December 2005 and July 2007. The mean age of the patients was 75.2 years old. Four of them had difficulty in walking due to the sequalae after stroke and five have been treated for psychoneurologic disorders. We investigated the operation time, the length of the anterior and posterior incisions, the amount of bleeding, the time untill walking after the operation, the total hospital stay, the recovery to activities of daily living and the complications such as dislocation. Results: The mean operating time was 93 minutes. The average anterior and posterior skin incision length was 6.4 cm and 7.2 cm, respectively. The mean amount of bleeding was 420 cc at the time of surgery and 230 cc postoperatively through a drain. The patients started walking at a mean of 3.3 (1 to 5) days after the operation and the mean hospitalization was 24.3 days. Fourteen patients went back to their pre-injured activities of daily living, except one case with an intraoperative periprosthetic fracture. As for complications, two cases (13.3%) of femoral fracture were intraoperatively observed and one case of skin necrosis on the anterior incision site occurred. There were not any cases of dislocation or infection. Conclusion: Two-incision bipolar hemiarthroplasty had advantages for rehabilitation in elderly patients who have a high risk of dislocation, as well as in the patients with muscle weakness. But the operation took a long time and it had a high complication rate.
