Purpose: Isolated acetabular fractures can occur as a result of a high energy impact on the hip joint. Surgery is required for most patients with an isolated acetabular fracture in order to alleviate pain, restore joint stability, and regain hip function. This study was conducted in order to examine the course of hip function in patients after surgical treatment of an isolated traumatic acetabular fracture. Materials and Methods: This prospective series of consecutive cases included patients who underwent surgery for treatment of an isolated acetabular fracture in a European level one trauma center between 2016 and 2020. Patients with relevant concomitant injuries were excluded. Scoring of hip function was performed by a trauma surgeon using the Modified Merle d'Aubigné and Postel score at six-week, 12-week, six-month, and one-year follow-up. Scores between 3-11 indicate poor, 12-14 fair, 15-17 good, and 18 excellent hip function. Results: Data on 46 patients were included. The mean score for hip function was 10 (95% confidence interval [CI] 7.09-12.91) at six-week follow-up (23 patients), 13.75 (95% CI 10.74-16.76) at 12-week follow-up (28 patients), 16 (95% CI 13.40-18.60) at six-month follow-up (25 patients), and 15.50 (95% CI 10.55-20.45) at one-year follow-up (17 patients). After one-year follow-up, the scores reflected an excellent outcome in 11 patients, good in five patients, and poor in one patient. Conclusion: This study reports on the course of hip function in patients who have undergone surgical treatment for isolated acetabular fractures. Restoration of excellent hip function takes six months.

The purpose of this study is to report the effect of korean medicine treatment for developmental dysplasia of the hip (DDH) in adults. A patient diagnosed with DDH had been treated with acupuncture, electroacupuncture, cupping therapy and chuna manual therapy for 8 weeks. The patient was evaluated by using range of motion (ROM) of hip joint, muscle strength of lower extremity, leg length, numeric rating scale (NRS) and Korean version of hip disability and osteoarthritis outcome score (K-HOOS). After the treatment, the patient had an improvement in the symptoms, pain, and activities of daily living of K-HOOS, especially the quality of life. In addition, NRS decreased from 7 to 4 points, and ROM and muscle strength also improved. The results of this study show that korean medicine treatment is effective and meaningful as one of the conservative treatment for DDH in adults.

소아 고관절 이형성증은 비구 또는 근위 대퇴골, 혹은 양쪽 모두를 포함하는 고관절의 부적절한 발달을 지칭하는 광범위한 개념이다. 초음파적 검사로 영아기의 고관절 탈구 진단이 간과되거나 수술적인 치료가 필요한 경우는 감소하고 있으나 모든 고관절 이형성증을 찾아내지는 못하고 있다. 아탈구가 없는 고관절 이형성증은 우연히 진단되며, 40대 이후 여자에서 퇴행성 관절염과 강한 연관성을 가진다. 아탈구를 동반한 고관절 이형성증은 아탈구의 정도에 따라 증상이 다양한 시기에 걸쳐 나타나며, 특히 여성에서 임신 중 발현되는 경우가 많다. 신생아에 대한 정확한 이학적 검사와 조기 치료는 이 질환의 양호한 결과를 위해 매우 중요하다. 진단의 간과를 막고 조기 치료의 기회를 제공하기 위해 저자는 고관절 이형성증이 의심스러운 2세 이하 영아 모두에게 고관절 검사를 추천한다. 본 연구에서는 고관절 이형성증의 진단 및 초기 치료에 대해 고찰해 보고자 한다.

The increase in the number of primary total hip arthroplasties that will be performed over the next several decades will lead to an increase in the incidence of periprosthetic fractures around the femoral stem. A search of targeted articles was conducted using on-line databases of PubMed (National Library of Medicine) and articles were obtained from January 2008 to November 2021. Reliable prediction of treatment can be achieved using the Vancouver classification; internal fixation is indicated in fractures involving a stable implant and revision arthroplasty is indicated in those with unstable prostheses. To the best of our knowledge, relatively fewer studies regarding periprosthetic proximal femur fractures of cemented stems have been reported. The focus of this review is on the risk factors and strategies for treatment of these fractures for periprosthetic femoral fractures around a cemented hip arthroplasty.

Study of east & west medical science documentary records of Hip joint pain lead to following conclusions. 1. Easten medicine classify hip joint pain with terms "Bi-chu-tong", "Bi chu in tong" "Bi-chu-choong-tong". 2. Easten medicine asorts cause of hip joint pain with external factor, such as exogenous energy, six yin evil energy and intrinsic factor, which are weakness caused by prolonged deasease, warm-heat evil. 3. In western medicine, causes that trigger hip joint pain are trauma, fracture, dislocation,and bacterial infection. 4. Treatment of hip joint disorder in western medicine, physiotherapy concerning conservative treatment, and pain control with drug treatment, kinesitherapy are used, and concernig fracture, operation is used. 5. In Eastern medicine, principle of treating hip joint pain, sung-juk-sa-ji(盛則寫之), hu-juk-bo-ji(虛則補之), yul-juk-jil-ji(熱則疾之), han-juk-yu-ji(寒則留之), ham-ha-juk-chim-ji(陷下則沈之), bul-sung-bul-hu(不盛不虛), yi-kyong-chui-ji(以經取之) is presented. This priciple of treatment was descended through ages and is now applied to treatments such as Acupuncture, Herbal, physical treatment based on so-san-eo-hyul(消散瘀血), seo-kun-tong-rak(舒筋通絡), so-ri-kwan-jul(疏利關節) principle. 6. In Eastern medicine, meridians used to treat hip joint pain are The Chok yangmyung wi Kyong(足陽明胃經), Chok taeum bi Kyong(足太陰脾經), Chock soyang dam Kyong(足少陽膽經), Chock guelum gan Kyong(足厥陰肝經). In conclusion, hip joint pain should be considered in relationship with internal organs and whole body system. Western & Eastern point of view should be carefully inspected and connected and intensive study of nervous system and meridian is required, in order to adopt best treatment for the patients.

가스터빈 고온부품 소재로 사용되는 Ni기 초합금 CM247LC 소재에 대한 최적 후처리 조건을 도출하기 위해 일방향 응고 주조법을 통한 봉상시험편을 제작하였다. 제작된 시험편은 HIP (Hot Isostatic Pressing) 처리 및 후열처리를 통해 기계적 특성과 미세 구조를 분석하여 최적의 HIP처리 조건을 도출하고자 하였다. CM247LC 소재의 경우 가스터빈 블레이드의 대체 소재로써 시제품 제작을 위한 다양한 연구가 진행되고 있다. 특히 블레이드의 경우 고속의 회전체로 고온 및 고압의 운전 환경에 노출되어 손상 시 후단의 블레이드와 베인에 대해 추가적인 설비 파손을 야기하여 막대한 경제적 손실을 초래할 수 있다. 따라서, CM247LC 소재가 블레이드 시제품 제작에 사용되기 위해서는 미세구조와 기계적 특성에 대한 신뢰성이 확보되어야 한다. 따라서 본 연구에서는 CM247LC 소재에 대한 기계적 특성 향상을 위해 전력연구원에서 설계한 기준에 따라 HIP처리 및 열처리를 수행하고 미세조직 특성 및 기계적 특성 분석을 통해 기존 1,300℃급 가스터빈 블레이드에 소재로 활용되고 있는 GTD111DS 소재와 기계적 특성을 비교 평가하였다.

Purpose: This study was undertaken in order to identify the characteristics of patients diagnosed with occult an hip fracture after hip trauma. Methods: We retrospectively reviewed the medical records and radiology reports of all patients who underwent hip skeletal computed tomography (CT) for suspected hip fractures but had normal initial X-rays after hip trauma between August 2006 and January 2012. The variables evaluated included age, gender, body mass index (BMI), accident mechanism, previous fracture, independence, late presentation, ability to bear weight, pain on passive rotation, tenderness of the groin area, diagnosis and treatment. Patients were divided into two groups, with hip fracture (occult hip fracture group) and without hip fracture (no fracture group) to evaluate the characteristics associated with an occult hip fracture. Results: The patients, a total of 139, had a mean age of 58.3 years and included 72 male patients(51.8%). The occult hip fracture group included 43 patients(30.9%). Of those 43, 21 patients(48.8%) had intertrochanteric or trochanteric fractures, 8 patients(18.6%) had femur neck fractures and 14 patients(32.6%) had acetabular fractures. Of the 43, 15 patients(34.9%) needed operative treatment. Age was higher in the occult hip fracture group than it was in the no fracture group($64.4{\pm}19.1$ years vs. $55.5{\pm}23.6$ years, p=0.021). A previous fracture was associated with the presence of a new fracture (p=0.014; OR=3.971, 95% CI=1.314-11.997). Conclusion: Further evaluation of patients who are older or have history of fractures is prudent, even though the initial X-rays are normal.

이 연구에서 저자들은 다음과 같은 결론을 얻었다. 1. 고관절 조영술은 수술전에 미리 유용한 정보를 줌으로써 수술전 계획을 세우고 수술을 체계적으로할 수 있을것으로 사료된다. 따라서 고관절 조영술은 도수정복 혹은 수술적 정복전에 필수적으로 시행하여야 할 것으로 사료된다. 2. 고관절 조영술은 비구 관절순, 원형인대의 평가에 매우 유용하였으며, 횡비구인대에 대한 정보는 제한적이었다. 3. 고관절 조영술은 단순 방사선 촬영에 비하여 중앙연각의 평가에 훨씬 유용하고 실제 병리적 소견에 합당한 정보를 주었다.

가스터빈 블레이드 재료로 사용되는 IN738LC 니켈기 초합금 주조재에 대하여 고온등압압축(HIP) 공정에 의한 미세조직 변화와 고온 피로수명에 미치는 영향을 조사하였다. 세부적으로 HIP 처리에 따른 주조결함 제거와 피로변형 열화재의 물성재생효과 확인에 중점을 두었으며, 이를 위하여 회전굽힘 피로시험을 실시하고 변형전후의 미세조직을 광학 및 주사전자현미경으로 관찰하였다. HIP 처리 전후의 미세조직과 피로수명을 비교, 평가한 결과, 주조재와 열처리재의 피로수명 차는 크지 않았으나 HIP 처리재의 피로수명은 이들과 비교하여 평균 60배 이상 증가한 것으로 나타났다. 또한 인위적으로 고온 피로변형을 가한 열화재를 대상으로 반복 HIP 처리한 결과, 열화 변형조직이 신재 상태로 거의 완전히 재생될 뿐만 아니라, 재료내에 미세하게 잔존하던 주조결함까지 부가적으로 제거됨에 따라 반복 HIP 처리에 의한 피로수명 연장 효과가 크게 나타났다.
