All-cause mortality risk in aged femoral intertrochanteric fracture patients

Introduction The 1-year mortality rate after femoral intertrochanteric fracture is higher than that of femoral neck fracture, which also belongs to hip fracture (Cui et al. in Arch Osteoporos 14(1):55, 2019). With the application of the concept of co-management model of orthopedics and geriatrics, the short-term and long-term mortality of all types of hip fractures has decreased (Van Heghe et al. in Calcif Tissue Int, 2021, https://doi.org/10.1007/s00223-021-00913-5). However, the mortality of Chinese femoral intertrochanteric fracture patients under this model has not been reported in the literatures. Aim This paper aims to study the risk factors of postoperative all-cause mortality in aged patients with femoral intertrochanteric fracture under the co-management model of orthopedics and geriatrics. Materials and methods This is a single-center prospective cohort study based on the real world, under the co-management of orthopedics and geriatrics, 363 patients aged ≥ 65 years with femoral intertrochanteric fracture were enrolled and followed up for 2–3 years; 52 patients were lost to follow up. Age, gender, body mass index (BMI), history of comorbidities, hip Bone Mineral Density (BMD), fracture history, 25(OH)D level, hemoglobin level, anti-osteoporosis treatment were risk factors to be tested. Kaplan–Meier survival curves and multivariate Cox proportional hazards models were constructed to analyze the impact of factors on all-cause mortality. Results (1) Most of the dead patients were older (the mean age was 83.4 years, compared with 79.8 years for surviving patients), with more complications and without anti-osteoporosis medication; gender, pre-fracture history, BMI, total hip BMD, hemoglobin, 25(OH)D had no difference between the dead and the living patients. (2) Elderly patients with Intertrochanteric fracture can benefit from the early treatment of Zoledronic Acid (within 3 days after the operation). Conclusion Under the co-management of orthopedics and geriatrics, to Chinese patients with Femoral Intertrochanteric fracture, Doctors should pay more attention to their age and chronic disease, and give anti-osteoporosis treatment if allowed.

Femoral Intertrochanteric Fracture and All-Cause Mortality Risk in Aged Osteoporosis Patients

Introduction：Clinicians pay attention to the risk factors of all-cause mortality after hip fracture, and expect to make intervention and choice. With the progress of diagnosis and treatment mode and technology, the composition and influence degree of risk factors changed in some extent. Materials and methods：This is a single-center prospective cohort study based on the real world, under the co management of orthopedics and geriatrics, 363 patients aged ≥65 years with femoral intertrochanteric fracture were enrolled and were followed up for 2-3 years; 52 patients were lost to follow up. Age, genders, body mass index (BMI), history of comorbidities, hip Bone Mineral Density (BMD), fracture history, 25(OH)D level, hemoglobin level, anti osteoporosis treatment were risk factors to be tested. Kaplan-Meier survival curves and multivariate Cox proportional hazards models were constructed to the analyzed impact of factors on all-cause mortality.Results (1) Most of the dead patients were older, with more complications and without anti osteoporosis medication; gender, pre-fracture history, BMI, total hip BMD, hemoglobin, 25(OH)D had no difference between the dead and the living patients. (2) Elderly patients with Intertrochanteric fracture can benefit from the early treatment of Zoledronic Acid (≤3days). Conclusions: Under the co management of orthopedics and geriatrics, to Chinese patients with Femoral Intertrochanteric fracture, Doctors should pay more attention to their age and chronic diseases, and give anti osteoporosis treatment if allowed.

Application of Wire-Assisted Reduction Guided by Minimally Invasive Wire Introducer in the Treatment of Irreducible Femoral Intertrochanteric Fractures

Background: Open reduction was often required in the treatment of irreducible femoral intertrochanteric fractures. A minimally invasive wire introducer was designed to assist the reduction of such fractures. The aim of our study was to investigate the clinical outcomes of this technique.Methods: Between 2013 and 2018, 92 femoral intertrochanteric fracture patients who were treated with intramedullary nail fixation and difficult reduction using the traction beds were retrospectively reviewed. Decision for surgery was based on the displacement of the fracture. The patients was divided into two groups, 31 in the control group and 61 in the observation group. The control group were received open reduction operation. And the observation group still received the closed reduction operation, using minimally invasive wire introducer to guide the wire and assist the fracture reduction. The operation time, blood loss, VAS scores, angulation, reduction, neck-shaft angle, redisplacement, limb length discrepancy, and union time were recorded.Results: All patients of two groups were successfully operated and were followed up for an average of 23.8 months. There was no statistical difference in baseline data between the two groups. The observation group had shorter operation time, lower VAS score and less intraoperative bleeding. And the datas are statistically different.Conclusion: Minimally invasive wire introducer is a good technology to guide the wire for irreduciblr femoral intertrochanteric fracture reduction. Using this technique, irreduciblr femoral intertrochanteric fractures could be restored and good clinical outcome was achieved.Level of evidence: Level IV; Case Series; Treatment Study

Similarities between Inferior-Center and Center-Center Lag Screw Positions in Femoral Intertrochanteric Fracture Surgeries

Background: The center-center lag screw position has been widely accepted as the optimal lag screw/helical blade position in femoral intertrochanteric fracture surgery to achieve a tip-apex distance (TAD) less than 25 mm. Despite the inferior-center lag screw/helical blade position having some biomechanical advantages, and the emergence of calcar-referenced tip-apex distance (CalTAD), the clinical differences between the two commonly placed lag screw/helical blade positions remain unclear. This study aimed to (1) report radiological outcomes in managing geriatric femoral intertrochanteric fractures, (2) identify the influences of positions of lag screw/helical blade, and (3) identify the relationship between implants and the values of TAD and CalTAD.Methods: We retrospectively assessed the clinical and radiographic findings of geriatric patients (age ≥ 55 years) who underwent surgery for acute closed femoral intertrochanteric fractures during 1-year period and were followed up a minimum of 6 months. The radiographic parameters and incidences of fixation failure were compared between the different lag screw and helical blade positions (center-center vs. inferior-center). Subgroup analyses of different implant types (extramedullary and intramedullary) were also performed for comparisons for different lag screw positions, and TAD and CalTAD beyond the normal standard value of 25 mm.Results: A total of 206 patients were included during the study period, with a 7.8% fixation failure. There were no differences in incidences of fixation failure between the commonly inserted lag screw/helical blade positions (center-center vs. inferior-center), regardless of the implant types. Those with a TAD > 25 mm had significantly higher incidence of fixation failure than those with a TAD ≤ 25 mm in the extramedullary plate (17.0% vs. 1.2%, p = 0.001), but not in the intramedullary nails (16.1% vs. 4.4%, p = 0.08). There were no significant differences in incidences of fixation failure between CalTAD ≤ 25 mm and CalTAD > 25 mm in either extramedullary or intramedullary implants. Conclusion: Although TAD > 25 mm might increase the fixation failure rate in extramedullary plates, an inferior-center lag screw/helical blade position could achieve comparable radiographic results as a center-center position after osteosynthesis for geriatric femoral intertrochanteric fractures.

A RETROSPECTIVE STUDY COMPARING PROXIMAL FEMORAL NAIL ANTI-ROTATION WITH CEMENTLESS BIPOLAR HEMIARTHROPLASTY FOR UNSTABLE FEMORAL INTERTROCHANTERIC FRACTURE

Background: Intertrochanteric femoral fractures are one of the most common types of bone fractures that are usually caused by severe direct or indirect force. It has also been estimated that nearly 50% of all the fractures are intertrochanteric fractures and the remaining are unstable fractures. Also, it has been found that the mortality related to hip fractures is as high as 15-20%. With an increase in the life expectancy of people, there has been a substantial increase in the number of patients with postmenopausal or senile osteoporosis. Aim: To compare Proximal femoral nail anti-rotation with cementless bipolar hemiarthroplasty for unstable femoral intertrochanteric fracture Methods: It was a retrospective study carried out at the Government Medical College, Baramati for a period of 1 year. One hundred patients were included for the scope of the study. Out of which 50 patients belonged to the PFNA group, and 50 patients belonged to the CPH group. Results: The number of patients in the PFNA group was 50 and that in the CPH group was 50. Both groups show male preponderance. The mean age among both the groups was almost the same, and there was no statistically significant difference among the two groups regarding the mean age. The mean operation time for PFNA was 54.15±16.1 mins, and that of the CPH group was 76.69±15.89 mins. The mean bleeding time for PFNA was 133.12±33.16 ml, and that of the CPH group was 289.25±44.01 ml. There was no statistically significant difference among the ASAA grade scores of the two groups. There was no statistically significant difference among the Evans-Jensen classification of the two groups. The mean length of hospital stay for PFNA group was 7.89±2.0 days, and the mean hospital stay for CPH group was 6.54±1.9 days. Conclusion: The current study depicted that CPH and PFNA are both safe and effective methods of treating elderly patients suffering from intertrochanteric fractures. However, it was found in the current study that CPH was found to have more mean operative time and increased blood loss. Still, the recovery and hospitalization time was almost similar in both the groups. Both the groups had almost similar ASA and Evans Jensen scores that made both the techniques equally safe
