Proximal Femur Fractures: Evaluating the Necessity of On-Call Surgery.

The decision of the Joint Federal Committee on the treatment of hip fractures stipulates that proximal femur fractures must be treated within the first 24 h. This leads to organizational and personnel difficulties in day-to-day care. Therefore, we investigated the question at what times of day we operate to maintain this timeline and whether there is a difference in the outcome for the patients according to treatment hours.

Surgical management and outcomes following atypical subtrochanteric femoral fractures - results from a matched-pair analysis of the registry for geriatric trauma of the German Trauma Society.

Background And Objectives: The outcomes of patients with atypical subtrochanteric fractures (ASFs) remain unclear. Data from a large international geriatric trauma registry were analysed to examine the outcome of patients with ASFs compared to patients with typical osteoporotic subtrochanteric fractures (TSFs).

Materials And Methods: Data from the Registry for Geriatric Trauma of the German Trauma Society (Deutsche Gesellschaft für Unfallchirurgie [DGU]) (ATR-DGU) were analysed.

Osteogenic Effect of a Bioactive Calcium Alkali Phosphate Bone Substitute in Humans.

(1) Background: The desire to avoid autograft harvesting in implant dentistry has prompted an ever-increasing quest for bioceramic bone substitutes, which stimulate osteogenesis while resorbing in a timely fashion. Consequently, a highly bioactive silicon containing calcium alkali orthophosphate (Si-CAP) material was created, which previously was shown to induce greater bone cell maturation and bone neo-formation than β-tricalcium phosphate (β-TCP) in vivo as well as in vitro. Our study tested the hypothesis that the enhanced effect on bone cell function in vitro and in sheep in vivo would lead to more copious bone neoformation in patients following sinus floor augmentation (SFA) employing Si-CAP when compared to β-TCP.

Value of Proximal Femur Geometry in Predicting Occult Hip Fracture.

: Patients with occult hip fractures are a difficult subgroup to treat. MRI is the gold standard for diagnosing occult proximal femur fractures but is costly and may not be readily available in an emergency setting. The purpose of this study was to determine whether changes in the proximal femur geometry can predict the likelihood of an occult hip fracture in patients presenting with hip pain following a ground-level fall.

[Effects of the COVID-19 pandemic on the course of geriatric trauma patients with proximal femoral fractures].

Background/objective: In 2020 the COVID-19 pandemic posed a major challenge to the healthcare system. The hypothesis is that the COVID-19 pandemic in 2020 had an impact on the care of older adults with proximal femoral fractures due to resource scarcity, regardless of whether or not the patient was infected.

Material And Methods: This study analyzed the data of 87 hospitals which entered 15,289 patients in the Geriatric Trauma Register ("AltersTraumaRegister DGU®", ATR-DGU) in Germany in 2019 and 2020.

Cemented Sacroiliac Screw Fixation versus Conservative Therapy in Fragility Fractures of the Posterior Pelvic Ring: A Matched-Pair Analysis of a Prospective Observational Study.

The aim of this study was to compare the outcome of cemented sacroiliac screw fixation to that of conservative treatment in nondisplaced fragility fractures of the sacrum during a 12-month follow-up. Therefore, matched-pair analysis including 40 patients from a previously performed prospective observational study was conducted. Pain was assessed using the visual analogue scale (VAS), functional capabilities and mobility were assessed using the Barthel index, and health-related quality of life (HRQL) was assessed using the EQ-5D questionnaire at 6 weeks, 6 months, and 12 months after the fracture, respectively.

Spinal anesthesia with better outcome in geriatric hip fracture surgery - An analysis of the Registry for Geriatric Trauma (ATR-DGU).

Background: Literature shows conflicting results regarding spinal (SA) or general anesthesia (GA) and their influence on the outcome of elderly patients with hip fractures. We, therefore, conducted an analysis from the Registry for Geriatric Trauma (ATR-DGU).

Methods: A retrospective, multicenter registry study including patients aged 70 years or above with hip fractures requiring surgery from 131 Centers for Geriatric Trauma (AltersTraumaZentrum DGU®) from 2016 to 2021.

The Influence of Malnutrition Measured by Hypalbuminemia and Body Mass Index on the Outcome of Geriatric Patients with a Fracture of the Proximal Femur.

Fractures of the proximal femur are a life-changing and life-threatening event for older people. Concomitant malnutrition has been described as an independent risk factor for complications and mortality. Therefore, we examined the influence of albumin and body mass index (BMI) as parameters for the nutritional state on the outcome after geriatric hip fracture surgery.

The Influence of a Modified 3rd Generation Cementation Technique and Vaccum Mixing of Bone Cement on the Bone Cement Implantation Syndrome (BCIS) in Geriatric Patients with Cemented Hemiarthroplasty for Femoral Neck Fractures.

Cemented hemi arthroplasty is a common and effective procedure performed to treat femoral neck fractures in elderly patients. The bone cement implantation syndrome (BCIS) is a severe and potentially fatal complication which can be associated with the implantation of a hip prosthesis. The aim of this study was to investigate the influence of a modified cementing technique on the incidence of BCIS.

The Predictive Value of the "Identification of Seniors at Risk" Score on Mortality, Length of Stay, Mobility and the Destination of Discharge of Geriatric Hip Fracture Patients.

Purpose: The German Society for Geriatrics recommends the "ISAR" questionnaire as a screening tool for patients ≥70 for geriatric screening in emergency rooms. Although the ISAR-score is collected routinely in the "AltersTraumaRegister DGU" (ATR-DGU), to date less is known about the predictive value of the "ISAR"-score in geriatric trauma patients.

Patients And Methods: Currently, 84 clinics participate in the ATR-DGU.

Impact of 2 different posterior screw fixation techniques on primary stability in a cervical translational injury model: A biomechanical evaluation.

Background: In case of injuries to the subaxial cervical spine, especially in osteoporotic bone, the question of the most stable operative technique arises. There are several techniques of screw fixation available regarding dorsal stabilization. This study investigates 2 techniques (lateral mass screws (LMS) vs cervical pedicle screws (CPS)) in the subaxial cervical spine regarding primary stability in a biomechanical testing using a translational injury model.

Effect of Direct Oral Anticoagulants on Treatment of Geriatric Hip Fracture Patients: An Analysis of 15,099 Patients of the AltersTraumaRegister DGU.

The increased use of direct oral anticoagulants (DOACs) results in an increased prevalence of DOAC treatment in hip fractures patients. However, the impact of DOAC treatment on perioperative management of hip fracture patients is limited. In this study, we describe the prevalence of DOAC treatment in a population of hip fracture patients and compare these patients with patients taking vitamin K antagonists (VKA) and patients not taking anticoagulants.

COVID-19 and Proximal Femur Fracture in Older Adults-A Lethal Combination? An Analysis of the Registry for Geriatric Trauma (ATR-DGU).

Objectives: COVID-19 can be a life-threatening illness, especially for older patients. The COVID-19 outbreak created a dramatic organizational challenge in treating infected patients requiring surgical treatment, like those suffering a proximal femur fracture, in a pandemic setting. We investigate the impact of a COVID-19 infection in patients with a proximal femur fracture not only on mortality but also on quality of life (QoL), length of stay, and discharge target.

Self-rated health status and activities of daily living in the first 12 months after fragility fractures of the pelvis-a prospective study on 134 patients.

Unlabelled: The aim of this study was to evaluate changes in activities of daily living and self-reported health status in the first year after fragility fractures of the pelvis. We found out that these fractures lead to a significant, long-lasting deterioration of both parameters, comparable with hip fractures.

Purpose: The aim of this prospective study was to evaluate the development and to identify influencing factors in activities of daily living (ADL) and self-reported health status (HS) in the first year after fragility fractures of the pelvis (FFP).

Open Reduction in Subtrochanteric Femur Fractures Is Not Accompanied by a Higher Rate of Complications.

: Hip fractures are among the most typical geriatric fractures. Subtrochanteric fractures are considered difficult to treat, and, to date, there is no consensus on the optimal surgical treatment. : We analyzed data from the Registry for Geriatric Trauma, which includes patients ≥ 70 years old with hip fractures or periprosthetic fractures requiring surgery (21,734 patients in 2017-2019).

Early Surgery Does Not Improve Outcomes for Patients with Periprosthetic Femoral Fractures-Results from the Registry for Geriatric Trauma of the German Trauma Society.

Appropriate timing of surgery for periprosthetic femoral fractures (PFFs) in geriatric patients remains unclear. Data from a large international geriatric trauma register were analyzed to examine the outcome of patients with PFF with respect to the timing of surgical stabilization. The Registry for Geriatric Trauma of the German Trauma Society (Deutsche Gesellschaft für Unfallchirurgie (DGU)) (ATR-DGU) was analyzed.

Screw-blade fixation systems for implant anchorage in the femoral head: Horizontal blade orientation provides superior stability.

Objectives: Despite continual improvement in the methods and devices used for treatment of proximal femoral fractures, unacceptably high failure rates remain. Novel screw-blade implant systems, combining a lag screw with a blade - the latter adding rotational stability to the femoral head - offer improvement of osseous purchase, especially in osteoporotic bone. The aim of this study was to compare biomechanically the head element (HE) anchorage of two screw-blade implant systems differing in blade orientation in the femoral head - vertical versus horizontal.

Height and volume restoration in osteoporotic vertebral compression fractures: a biomechanical comparison of standard balloon kyphoplasty versus Tektona® in a cadaveric fracture model.

Background: Standard balloon kyphoplasty represents a well-established treatment option for osteoporotic vertebral compression fractures. Aim of the present study was to evaluate two different methods of percutaneous augmentation (standard balloon kyphoplasty (BKP) versus Tektona® (TEK)) with respect to height restoration.

Methods: Four-teen vertebral bodies of two female cadavers were examined.

Differences of hemiarthroplasty and total hip replacement in orthogeriatric treated elderly patients: a retrospective analysis of the Registry for Geriatric Trauma DGU.

Purpose: Medial femoral neck fractures are typically managed with hemiarthroplasty (HA) or total hip arthroplasty (THA) in elderly patients. There is a debate as to which treatment predominates. The literatures have reported better outcomes for those patients with proximal femur fracture who were treated in an orthogeriatric centres compared to standard orthopaedic hospitals.

Medical and economic consequences of perioperative complications in older hip fracture patients.

Unlabelled: Patients suffering from complications during inpatient treatment after hip fracture surgery are associated with a worse mid-term outcome. While surgically treatable complications only delay the healing process, internal complications seem to worsen the outcome in the long run. All complications come with significant increased costs during the hospital stay.

Type of underlying fracture after the surgical treatment of geriatric trauma patients has no effect on mortality during intensive care treatment.

Aim: Due to demographic change, the number of geriatric patients is still rising. Although hip fractures are the subject of current research, little is known about the remaining geriatric trauma entities. The aim of this study was to collect data of the age-related traumatological intensive care unit (ICU) population, its underlying diagnosis, and the influence on mortality and length of stay in the ICU.

Development of the Barthel Index 5 years after hip fracture: Results of a prospective study.

Aim: The importance of proximal femoral fractures is increasing due to demographic change. Despite appropriate care, these are associated with poor results. We are still lagging behind, and require information on the long-term functional outcome of these patients and the predictive factors involved.

Predictors of long-term survival after hip fractures?-5-year results of a prospective study in Germany.

Unlabelled: The incidence of hip fractures is increasing due to demographic transition. Data on long-term survival and influencing factors are sparse. Our prospective observational study with 395 patients shows a survival of 38% after 5 years.
