Clinical Results of Complex Subtrochanteric Femoral Fractures with Long Cephalomedullary Hip Nail
( Kwang-kyoun Kim ),( Yougun Won ),( Danica H. Smith ),( Gi-soo Lee ),( Hee Young Lee ) 대한고관절학회 2017 Hip and Pelvis Vol.29 No.2
Purpose: Good results of the cephalomedullary nails have been reported in proximal femoral fractures recently. Based on length of nails and shape of screws fixed in a femoral head for proximal fragment fixation, the proper nail length was in dispute. The purpose of this study was to evaluate the clinical and radiological results of a long cephalomedullary hip nail for the treatment of comminuted subtrochanteric femoral fractures. Materials and Methods: Twenty-one consecutive patients with severe subtrochanteric femoral fractures who had undergone intramedullary fixation using long-PFNA II between March 2010 and March 2013 were followed-up for over 12 months. Their mean age was 64.8 years old (range, 43-85 years). Sixteen of 22 cases were high energy trauma. According to Seinsheimer`s classification, 5 cases were type IV and 16 cases were type V. For radiological assessment, time to union, change of neck-shaft angle, sliding length, tip-apex distance (TAD) and leg length discrepancy (LLD) were measured. For clinical evaluation, a modified Koval index was investigated. Results: Mean operation time was 96 minutes. An average decrease of neck-shaft angle was 4.5˚. The average sliding length of the helical blade was 4.2 mm. Average LLD was 3.0 mm, and TAD was 23.0 mm. Mean modified Koval index score at final follow-up was 4.6 points. All the 21 subtrochanteric fractures healed uneventfully on an average of 24.2 weeks (range, 18-30 weeks). Conclusion: Long cephalomedullary hip nail provides excellent clinical and radiological outcomes in the comminuted subtrochanteric fracture.

Kwang-Kyoun Kim,Tae-Kyun Kim,Yougun Won,Won-Sub Sung 대한골다공증학회 2015 Osteoporosis and Sarcopenia Vol.1 No.1
Purpose: The aim of this study is to evaluate clinical characteristics of osteoporosis management in patients with Parkinson's disease. Materials and methods: Data on patients with Parkinson's disease was collected from March, 2000 to March, 2013 at single institution. We investigated portion of BMD test, portion of diagnosed osteoporosis, portion of pharmacological treatment, prevalence and location of primary fractures and presence of second-fractures after primary fracture on in patients with idiopathic Parkinson's disease. Results: Total of 865 patients were included. Among the 865 subjects, the number of patients who underwent diagnostic studies was 189 (21.8%) and the number of patients who was diagnosed with osteoporosis with BMD test was 72 (38.1%), which was 8.3% of the whole patients. Among the patients diagnosed with osteoporosis, the number of patients who were administered with osteoporosis medication for more than 1 year was 49 (68.0%), which was 5.6% of the whole patients. One hundred thirty (15.0%) patients suffered from low energy fractures. Of the 130 fracture sites, 57(43.3%) occurred in proximal femur, 47 (36.1%) of in vertebra, 8 (6.1%) in wrist, 4 (3.0%) in proximal humerus and 14 (10.7%) elsewhere. Twenty two (16.9%) patients suffered from second fracture after the primary fracture. Conclusion: In Parkinson's disease patients, the diagnosis and pharmacologic treatment of osteoporosis were not done adequately, and thus both medical staffs and patients should take this matter into consideration.

경골 원위부 골절에서 석회화된 전경골 동맥의 포착 -증례 보고-
양규현 ( Kyu Hyun Yang ),원유건 ( Yougun Won ),김상범 ( Sang Bum Kim ),박원근 ( Won Kuen Park ),정유선 ( You Sun Jung ) 대한골절학회 2016 대한골절학회지 Vol.29 No.1
경골 원위부에서 전경골 동맥은 전경골 표면에서 가까이 전외측 방향으로 주행한다. 임상적 상황에서 혈관 자체에 대한 평가없이는 전경골 동맥의 손상이나 포착은 쉽게 판단하기 어려운 경우가 많으며 이는 후경골 동맥으로 측부 분지되어 혈류를 공급받는 족배동맥의 촉지가 잘 유지되기 때문이다. 포착된 전경골 동맥은 응급실에서 비관혈적 정복술을 시행하거나 수술실에서 관혈적 정복술 및 내고정술을 시행하는 과정에서 의인성 손상으로 이어질 수 있다. 이를 방지하기 위해서는 포착 가능성에 대한 주의를 필요로 한다. 본 증례에서 우리는 조영제 없이도 석회화로 인해 단순 방사선 영상 및 컴퓨터 단층촬영에서 포착된 전경골의 드문 예를 경험하여 보고하고자 한다. In the distal third of the tibia, the anterior tibial artery runs close to the anterolateral surface of the tibial cortex. In a clinical situation, without vascular evaluation, injury or entrapment of the anterior tibial artery is difficult to detect. Because, an intact dorsalis pedis pulse is supplied with the collateral vessels of the posterior tibial artery. An entrapped anterior tibial artery can be injured during closed reduction in an emergency room or open reduction and internal fixation in the operating room. Care must be taken to prevent iatrogenic anterior tibial artery. In this case, an entrapped anterior tibial artery was observed in a simple radiograph and computed tomograph without contrast media for the vessel. We report on a rare case of calcified anterior tibial artery entrapment in a distal tibial fracture.
