Ipsilateral fractures of proximal femur with shaft and condylar region are very rare. Current concept of management is based on fixation of each fracture as independent entity using separate fixation modalities for proximal and distal parts of femur. However, we considered that antegrade femoral nailing with cephalomedullary screw fixation is a good option for ipsilateral multi-level femoral fractures. Here, we present an experience of satisfactory treatment for ipsilateral femoral neck fracture, subtrochanteric fracture, comminuted shaft fracture with supracondylar fracture following road traffic accident.

This report showed the clinical outcome of an elderly patient with a femoral neck fracture who was treated non-operatively with Korean medical treatment. The patient had acupuncture, herbal medication, moxibustion, and participated in physical rehabilitation for 3 months. The effects of Korean medical treatment were measured every 2 weeks using the numeric rating scale (NRS) and the Harris hip score (HHS). After treatments, the NRS score for hip pain decreased from 8 to 2, and the HHS increased from 0 to 43. A 42-month follow-up showed the patient's NRS score was 0 and the HHS was 61. Furthermore, an X-ray showed complete union of the femoral neck fracture with no suspicion of avascular necrosis. These results suggest that Korean medical treatment can effectively reduce pain and aid rehabilitation in patient with femoral neck fractures with no surgery, resulting in complete union of the fracture.

Objectives: Osteoporosis is the most common metabolic disease of the bone, and is one of the most important major public health problems world wide. It is more occurred in female than male, but as the osteoporosis of men is increasing, therefore bone fractures of men are increasing. So we investigated the factors which are related to Bone Mineral Density(BMD) of male for prevention of osteoporosis. Methods: We measured the Bone Mineral Density(BMD) of lumbar spine($L_2$-$L_4$) and femoral neck in 5198 male, using dual energy X-ray absorptionmetry(DEXA; DPX-alpha). And then we analysed the 8 factors - age group, bone mass index(BMI), amount of smoking, drinking, exercise, and fast blood sugar, gastric disease, thyroid disease - which are related to BMD of male. Results: 1. In age group according to ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$, T-score was the highest at 17-24(三八歲) years group and decreased rapidly after 57-64(八八歲) years group in both lumbar spine($L_2$-$L_4$) and femoral neck. Therefore we concluded that T-score of male in lumbar spine($L_2$-$L_4$) and femoral neck change according to age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$. 2. In BMI(body mass index), T-score of lumbar spine($L_2$-$L_4$) and femoral neck were the highest in obese group than non-obese group. In comparison of age group according to BMI, T-score of lumbar spine($L_2$-$L_4$) was significant difference in 17-72 years group and T-score of femoral neck was in 25-72 years group. 3. In exercise, T-score of lumbar spine($L_2$-$L_4$) and femoral neck was increasing as exercising more. In comparison of age group according to exercise, Both T -score of lumbar spine and femoral neck were significant difference in 25-72 years old. 4. T-score of lumbar spine($L_2$-$L_4$) was the highest in men who have taken exercise daily, and T-score of femoral neck was the highest in men who have taken exercise 1-3 times for a week. Conclusions : The age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$ is related to BMD of men. And risk factors - BMI, exercise - are related to BMD of men. Therefore we expect that this study will help for prevention of osteoporosis of men.

목적 대퇴골 경부 골절 환자를 대상으로 골다공증 평가를 위해 다중검출 전산화단층촬영(multidetector computed tomography; 이하 MDCT)에서의 감쇠 계수(Hounsfield unit; 이하 HU)와 이중 에너지 X선 흡수 계측법(dual energy X-ray absorptiometry; 이하 DXA)을 비교하였다. 대상과 방법 2016년 6월부터 12월까지 MDCT와 DXA를 모두 시행한 42명의 대퇴골 경부 골절 환자가 본 연구의 대상으로 포함되었다. MDCT에서는 정상 대퇴골 경부의 해면골에서 HU를 측정하였으며 DXA에서는 동 부위의 골밀도 및 T 값을 얻었다. HU와 골밀도 및 T 값의 상관관계를 Spearman 상관계수를 이용하여 분석하였다. 결과 대퇴골 경부 골절 환자의 골밀도와 T 값의 평균은 각각 0.650 g/cm²과 -2.4이었다. 정상, 골감소증, 골다공증 환자 군의 HU의 평균은 각각 131.9, 98.9, 41.3이었다. HU는 골밀도(r² = 0.670; p < 0.001) 및 T 값(r² = 0.676; p < 0.001) 모두와 양의 상관관계를 보였다. 결론 다중검출 전산화단층촬영에서 감쇠계수의 측정은 골다공증 선별검사를 위한 유용한 진단적 도구가 될 수 있다.

Purpose: This study investigates the relationship between preoperative neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-C-reactive protein ratio (LCR), albumin, and 2-year mortality in elderly patients having hemiarthroplasty for displaced femoral neck fracture (FNF). Materials and Methods: We retrospectively reviewed 284 elderly patients who underwent hemiarthroplasty for Garden type IV FNF from September 2014 to September 2020. Using the receiver operating characteristic curve, optimal cutoff values for LCR, NLR, and albumin were established, and patients were categorized as low or high. Associations with 2-year mortality were evaluated through univariate and multivariate Cox regression analyses. Results: Of the 284 patients, 124 patients (45.9%) died within 2 years post-surgery. The optimal cutoff values were: LCR at 7.758 (specificity 58.5%, sensitivity 25.0%), NLR at 3.854 (specificity 39.2%, sensitivity 40.0%), and albumin at 3.750 (specificity 65.9%, sensitivity 21.9%). Patients with low LCR (<7.758), high NLR (≥3.854), and low albumin (<3.750) had a statistically significant reduced survival time compared to their counterparts. Conclusion: Lower preoperative LCR and albumin levels, along with higher NLR, effectively predict 2-year mortality and 30-day post-surgery complications in elderly patients with Garden type IV FNF undergoing hemiarthroplasty.

Objective: This study aimed to investigate the usefulness of bone single-positron emission tomography/computed tomography (SPECT/CT) of the hip in predicting the later occurrence of avascular necrosis (AVN) after slipped capital femoral epiphysis (SCFE) or femoral neck fracture in pediatric patients. The quantitative parameters of SPECT/CT useful in predicting AVN were identified. Materials and Methods: Twenty-one (male:female, 10:11) consecutive patients aged < 18 years (mean age ± standard deviation [SD], 11.0 ± 2.7 years) who underwent surgery for SCFE or femoral neck fracture and postoperative bone SPECT/CT were included. The maximum standardized uptake value (SUV), mean SUV, and minimum SUV of the femoral head were measured. The ratios of the maximum SUV, mean SUV, and minimum SUV of the affected femoral head to the contralateral side were determined. Patients were followed up for > 1 year after the surgery. The SPECT/CT parameters were compared between patients who developed AVN and those who did not. The accuracy of SPECT/CT parameters for predicting AVN was assessed. Results: Six patients developed AVN. There was a significant difference in the ratio of the mean SUV among patients who developed AVN (mean ± SD, 0.8 ± 0.3) and those who did not (1.1 ± 0.2, p = 0.018). However, there were no significant differences in the ratios of the maximum and minimum SUV between the groups (all p = 0.205). For the maximum, mean, and minimum SUVs, no significant differences were observed between the groups (p = 0.519, 0.733, and 0.470, respectively). The cutoff mean SUV ratio of 0.87 yielded a 66.7% sensitivity and 93.2% specificity for predicting AVN. Conclusion: Quantitative bone SPECT/CT is useful for evaluating femoral head viability in pediatric patients with SCFE or femoral neck fractures. Clinicians should consider the high possibility of later AVN development in patients with a decreased mean SUV ratio.

Purpose: The purpose of this study is to describe a method of inserting cement in the femoral head before fixation with dynamic hip screw to prevent screw cut out due to osteoporosis and to evaluate its clinical outcome in these patients. Materials and Methods: In this prospective study, 30 patients aged 60 years and older with intertrochanteric fracture were included. Bone mineral density was measured. After reaming of the femoral head and neck with a triple reamer and polymethyl methacrylate, bone cement was introduced into the femoral head using a customized nozzle and a barrel fitted on a cement gun. A Richard screw was inserted and the plate was fixed over the femoral shaft. Patients were mobilized and clinical outcomes were rated using the Salvati and Wilson's scoring system. Results: More patients included in this study were between 66 and 70 years old than any other age group. The most common fracture according to the Orthopaedic Trauma Association classification was type 31A2.2 (46.7%). The T-score was found to be $-2.506{\pm}0.22$ (mean${\pm}$standard deviation); all patients were within the range of -2.0 to -2.8. The duration of radiological union was $13.67{\pm}1.77$ weeks. Salvati and Wilson's scoring at 12 months of follow up was $30.96{\pm}4.97$. The majority of patients were able to perform their normal routine activities; none experienced implant failure or screw cut out. Conclusion: Bone cement augmentation may effectively prevent osteoporosis-related hardware complications like screw cut out in elderly patients experiencing intertrochanteric fractures.

Osteoporosis is a disease in which the risk of bone fractures increases due to a decrease in bone density caused by aging. Osteoporosis is diagnosed by measuring bone density in the total hip, femoral neck, and lumbar spine. To accurately measure bone density in the lumbar spine, the vertebral region must be segmented from the lumbar X-ray image. Deep learning-based automatic spinal segmentation methods can provide fast and precise information about the vertebral region. In this study, we used 695 lumbar spine images as training and test datasets for a deep learning segmentation model. We proposed a lumbar automatic segmentation model, CM-Net, which combines the center point of the spine and the modified U-Net network. As a result, the average Dice Similarity Coefficient(DSC) was 0.974, precision was 0.916, recall was 0.906, accuracy was 0.998, and Area under the Precision-Recall Curve (AUPRC) was 0.912. This study demonstrates a high-performance automatic segmentation model for lumbar X-ray images, which overcomes noise such as spinal fractures and implants. Furthermore, we can perform accurate measurement of bone density on lumbar X-ray images using an automatic segmentation methodology for the spine, which can prevent the risk of compression fractures at an early stage and improve the accuracy and efficiency of osteoporosis diagnosis.
