“…However, unlike these two kinds of fractures, an isolated intertrochanteric fracture rarely causes avascular necrosis. This kind of extracapsular fracture has only a limited effect on the blood supply of the femoral head [19]. However, in this study, avascular necrosis was identi ed in 4/17 patients.…”

“…This indicates that after causing fractures at two sites around the hip, the impact from the trauma still may not be fully absorbed and may cause the hip joint to be dislocated [7,[16][17][18]. According to the Evans classi cation, most intertrochanteric fractures are type 3 or type 4, which are considered unstable [19,20]. The most common type of acetabular fracture is a posterior wall fracture, which has a weaker in uence on stress distribution but a stronger in uence on the stability of the hip joint [13,21,22].…”

Background Fractures involving both the acetabulum and the ipsilateral femoral trochanter are rarely reported. The aims of our study were to identify the etiological characteristics, summarize the treatment methods, and analyze the mid- to long-term prognosis for this kind of rare injury. Methods A total of 18 patients who were treated in our hospital for a combination of ipsilateral acetabular fracture and intertrochanteric fracture from 2003 to 2013 was retrospectively analyzed. The etiology, fracture classifications, treatment and prognosis of patients were identified. Results We followed up with patients for 6.2 years to 16 years. In this study, injuries occurred most commonly via traffic accidents, followed by falls from a tall height and crushing injury. Six patients had posterior dislocation of the hip joint. Evans type 3 fracture and Letournel type 1 fracture were the most common fractures among these patients. All patients received internal fixation for their intertrochanteric fracture. Some patients also received internal fixation for their acetabular fracture. However, for the other patients, acetabular fractures were treated conservatively or with fracture fragment resection. One elderly (87 years) female patient had pulmonary disease and died at 24 days postoperatively. In other patients, fractures all achieved bony healing. Twelve patients achieved excellent and good results (Harris score ≥ 80 points), and 5 patients achieved fair and poor results (Harris score < 80 points). The proportion of patients who achieved an excellent-good Harris score was 70.6%. Dislocation of the hip was found to be an independent risk factor (HR = 9.194, 95% CI = 1.024–82.515) for poor patient outcomes. Conclusion The detailed characteristics of patients with acetabular fracture and ipsilateral intertrochanteric fracture were identified in this study. For patients who undergo surgical treatment, fracture healing is usually achieved. However, the occurrence of complications, especially avascular necrosis, is the major cause of poor prognosis. Dislocation of the hip joint at the time of injury is considered to be an important risk factor for poor prognosis.

“…Osteoporosis is associated with various comorbidities of the elderly and the medications used to treat these can affect one another and worsen the patient's condition; in some cases, it may result in osteoporotic fractures. [123] Compared to other fractures, hip fracture tends to have more severe consequences in the elderly hip fracture; it has high mortality and morbidity. [4] Although the risk varies depending on the characteristics of each study subject and the surgical method, one meta-analysis reports a 1-year cumulative mortality rate of hip fracture from 5.9% to 59%.…”

The elderly population growth rate is extremely high in Korean society, and life expectancy is close to 85 years old for women and 80 for men as of people born in 2015. The future hip fracture prediction model of Korea shows that the elderly hip fracture rate will increase by 1.4 times by 2025, which will impose a serious socioeconomic burden on Korean society and become a key issue of public health management. The fracture liaison service (FLS) is defined adequate treatment and services for patients over 50 years old with fragility fractures, enabling systematic identification and decreasing the risk of subsequent osteoporotic fractures. In Korean society, the introduction of FLS, which is verified not only in the socioeconomic aspects but also in the treatment of patients, is thought to be essential. However, the challenges that need to be addressed in order to implement FLS include the lack of awareness regarding the necessity of this system, the lack of healthcare systems, and inadequate policies. In the future, further studies on the FLS and its clinical and socioeconomic effects for the Korean medical system will be necessary.

“…It is estimated that in 2050, there will be 6.3 million hip fractures worldwide, with approximately 90% occurring in people above 65 years of age and approximately 50% being intertrochanteric fractures [1][2][3][4] . Intertrochanteric fractures account for approximately 3.40% of all fractures in adults and are associated with the risk of many complications and even death [5][6][7][8][9] . The intertrochanteric fracture-related mortality rate is as high as 30% in the first 12 months after injury, especially in the elderly with limited mobility 10 .…”

Objective: To using finite element analysis to investigate the effects of the traditional titanium alloy Gamma nail and a biodegradable magnesium alloy bionic Gamma nail for treating intertrochanteric fractures.Methods: Computed tomography images of an adult male volunteer of appropriate age and in good physical condition were used to establish a three-dimensional model of the proximal femur. Then, a model of a type 31A1 intertrochanteric fracture of the proximal femur was established, and the traditional titanium alloy Gamma nails and biodegradable magnesium alloy bionic Gamma nails were used for fixation, respectively. The von Mises stress, the maximum principal stress, and the minimum principal stress were calculated to evaluate the effect of bone ingrowth on stress distribution of the proximal femur after fixation.Results: In the intact model, the maximum stress was 5.8 MPa, the minimum stress was −11.7 MPa, and the von Mises stress was 11.4 MPa. The maximum principal stress distribution of the cancellous bone in the intact model appears in a position consistent with the growth direction of the principal and secondary tensile zones. After traditional Gamma nail healing, the maximum stress was 32 MPa, the minimum stress was −23.5 MPa, and the von Mises stress was 31.3 MPa. The stress concentration was quite obvious compared with the intact model. It was assumed that the nail would biodegrade completely within 12 months postoperatively. The maximum stress was 18.7 MPa, the minimum stress was −12.6 MPa, and the von Mises stress was 14.0 MPa. For the minimum principal stress, the region of minimum stress value less than −10 MPa was significantly improved compared with the traditional titanium alloy Gamma nail models. Meanwhile, the stress distribution of the bionic Gamma nail model in the proximal femur was closer to that of the intact bone, which significantly reduced the stress concentration of the implant. Conclusion:The biodegradable magnesium alloy bionic Gamma nail implant can improve the stress distribution of fractured bone close to that of intact bone while reducing the risk of postoperative complications associated with traditional internal fixation techniques, and it has promising clinical value in the future.
