[Effects of the COVID-19 pandemic on the course of geriatric trauma patients with proximal femoral fractures]. / Auswirkungen der COVID-19-Pandemie auf den Verlauf von alterstraumatologischen Patienten mit proximaler Femurfraktur.

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. In this study we analyzed the influence of the COVID-19 pandemic on the inpatient treatment of hip fractures as well as the mid-term follow-up during the first 120 days. For the main analysis, we compared patients documented during the COVID-19 pandemic in 2020 (April-December) with a control group in 2019 (April-December). Additionally, we performed a subgroup analysis of the periods with high COVID-19 incidence rates. RESULTS: Between 2019 and 2020 a total of 11,669 patients (2020: n = 6002 patients vs. 2019: n = 5667 patients) were included in this study. Only minor differences were found between the patients treated during the pandemic; however, when the COVID-19 incidence in Germany was greater than 50/100,000 residents, significantly fewer patients (p < 0.001) were discharged to a geriatric rehabilitation ward (27.2% vs. 36.3%) and an increased mortality rate during inpatient treatment was determined (8.4% vs. 4.6%) (p < 0.001). DISCUSSION: The healthcare system was able to respond to the pandemic and patients' clinical courses were not impaired as long as the incidences were low. Nevertheless, the healthcare system reached its limits in times of higher incidence, which was also directly reflected in the patient outcome, mortality and place of discharge.

Increased Geriatric Treatment Frequency Improves Mobility and Secondary Fracture Prevention in Older Adult Hip Fracture Patients-An Observational Cohort Study of 23,828 Patients from the Registry for Geriatric Trauma (ATR-DGU).

Interdisciplinary orthogeriatric care of older adult hip fracture patients is of growing importance due to an ageing population, yet there is ongoing disagreement about the most effective model of care. This study aimed to compare different forms of orthogeriatric treatment, with focus on their impact on postoperative mobilization, mobility and secondary fracture prevention. In this observational cohort study, patients aged 70 years and older with a proximal femur fracture requiring surgery, were included from 1 January 2016 to 31 December 2019. Data were recorded from hospital stay to 120-day follow-up in the Registry for Geriatric Trauma (ATR-DGU), a specific designed registry for older adult hip fracture patients. Of 23,828 included patients from 95 different hospitals, 72% were female, median age was 85 (IQR 80-89) years. Increased involvement of geriatricians had a significant impact on mobilization on the first day (OR 1.1, CI 1.1-1.2) and mobility seven days after surgery (OR 1.1, CI 1.1-1.2), initiation of an osteoporosis treatment during in-hospital stay (OR 2.5, CI 2.4-2.7) and of an early complex geriatric rehabilitation treatment (OR 1.3, CI 1.2-1.4). These findings were persistent after 120 days of follow-up. Interdisciplinary treatment of orthogeriatric patients is beneficial and especially during in-patient stay increased involvement of geriatricians is decisive for early mobilization, mobility and initiation of osteoporosis treatment. Standardized treatment pathways in certified geriatric trauma departments with structured data collection in specific registries improve outcome monitoring and interpretation.

Which factors influence treatment decision in fragility fractures of the pelvis? - results of a prospective study.

BACKGROUND: The aim of the present study was to describe specific characteristics of patients suffering from pelvic fragility fractures and evaluate factors that might influence treatment decisions which may optimize treatment pathways and patient mobility in the future. METHODS: A prospective study with patients suffering from fractures of the pelvis and aged 60 years or above was performed between 2012 and 2016. Data acquisition took place at admission, every day during hospitalization and at discharge. RESULTS: One hundred thirty-four patients (mean age of 79.93 (± 7.67) years), predominantly female (84%), were included. Eighty-six patients were treated non-operatively. Forty-eight patients underwent a surgical procedure. The main fracture types were B2 fractures (52.24%) and FFP IIb fractures (39.55%). At the time of discharge, pain level (NRS) could be significantly reduced (p <  0.001). Patients who underwent a surgical procedure had a significantly higher pain level on day three and four compared to the non-operative group (p = 0.032 and p = 0.023, respectively). Significant differences were found in the mobility level: patients treated operatively on day four or later were not able to stand or walk on day three as compared to non-operatively treated patients. Regarding B2 fractures, a significantly higher mobility level difference between time of admission and discharge was found in patients treated with a surgical procedure compared to patients treated non-operatively (p = 0.035). CONCLUSIONS: Fracture type, mobility level and pain level influence the decision to proceed with surgical treatment. Especially patients suffering from B2 fractures benefitted in terms of mobility level at discharge when treated operatively. LEVEL OF EVIDENCE: II.

Cement augmentation of an angular stable plate osteosynthesis for supracondylar femoral fractures - biomechanical investigation of a new fixation device.

BACKGROUND: Implant anchorage in highly osteoporotic bone is challenging, since it often leads to osteosynthesis failure in geriatric patients with supracondylar femoral fractures. Cementation of screws is presumed to prevent such osteosynthesis failure. This study aimed to investigate the effect of a newly designed, cementable fenestrated condylar screw for plate fixation in a biomechanical setting. METHODS: Eight pairs of osteoporotic cadaver femora with an average age of 77 years, ranging between 62 and 88 years, were randomly assigned to either an augmented or a non-augmented group. In both groups an instable 33-A3 fracture according to the AO / OTA classification was fixed with an angular stable locking plate. All right samples received a cement augmentation of their fenestrated condylar screws with calcium phosphate bone cement (CPC). Mechanical testing was performed at a load to failure mode by cyclic axial loading, using a servohydraulic testing machine. RESULTS: With a mean of 2475 N (95% CI: 1727-3223 N), the pressure forces resulting in osteosynthesis failure were significantly higher in specimen with cemented condylar screws as compared to non-cemented samples (1875 N (95% CI: 1320-2430 N)) (p = 0.024). In both groups the deformation of the constructs, with the distal screws cutting through the condylar bone, were the most frequent cause for failure. Analysis of axial stiffness (p = 0.889) and irreversible deformity of the specimens revealed no differences between the both groups (p = 0.161). No cement leakage through the joint line or the medial cortex was observed. CONCLUSION: Based on the present study results, the newly introduced, cementable condylar screw could be an encouraging feature for the fixation of supracondylar femoral fractures in patients with reduced bone quality in terms of load to failure accuracy of the cement application.

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

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. Significant risk factors were male gender, higher age, lower Barthel Index, lower Charlson Comorbidity Score, lower Mini-Mental State Examination, and delirium during hospitalization. PURPOSE: The incidence of hip fractures is increasing due to demographic transition. Until now, they are associated with poor results and high mortality rates. Data on long-term survival and influencing factors are sparse. Therefore, a prospective observational study was conducted. METHODS: Patients ≥ 60 years with hip fracture were included in this prospective study between 2009 and 2011. Demographic parameters, as well as ASA Score, pre-fracture Barthel Index and EQ-5D, Mini-Mental State Examination, Charlson Comorbidity Score, fracture type, type of surgical treatment, place of discharge, and arising complications were registered. Outcome parameter was survival during a 5-year follow-up period. RESULTS: A total of 539 patients attended to our emergency room during the period of recruitment. The recruitment rate was 75%. A total of 402 patients were included; 7 were lost to follow-up, and 152 (38%) survived the study period. The mortality was more than 25% in the first year after fracture. Subsequently, it was between 7 and 9% per year. In the multivariate analysis, significant risk factors for dying were male gender (p = 0.002), higher age (p < 0.001), lower Charlson Comorbidity Score (p = 0.033), lower Barthel Index (p = 0.024), lower Mini-Mental State Examination (p = 0.002), and occurrence of delirium during hospitalization (p = 0.008). CONCLUSION: Our results confirm poor results of geriatric patients after hip fracture. While early results might be influenced by optimal fracture care, long-term results seem to be determined by not changeable patient factors. Nevertheless, more than one third of surviving patients after 5 years justify the elaborate treatment algorithms for these fragile patients.

Epidemiology of hip fractures : Systematic literature review of German data and an overview of the international literature.

BACKGROUND: Hip fractures are regarded as a worldwide epidemic and a major public health concern. Changing risk factors, local differences and temporal trends contribute to the particular epidemiology of hip fractures. This overview gives a comprehensive insight into the epidemiology of hip fractures and reviews where German data have contributed to the literature. METHODS: The review of the epidemiology of hip fractures in Germany is based on a systematic literature search in PubMed. Information about the global epidemiology of hip fractures was provided by a selective literature review focusing on specific aspects of the epidemiology of hip fractures. RESULTS: Hip fracture rates vary more than 100-fold between different countries. In most high-income countries, a rise in age-standardized hip fracture rates was observed until the 1980s and 1990s and a decrease thereafter. Such a decrease has not been observed for Germany so far. Many factors, diseases and drugs have been found to be associated with hip fractures and there is some evidence that fracture risk in later life is already programmed during fetal life and early childhood. Of the hip fracture burden 50% occur in people with disability and in need of care. In nursing homes approximately 4 fractures can be expected in 100 women per year. In people with intellectual or developmental disabilities comparable risks of hip fracture occur 10-40 years earlier than in the general population. Incidence of disability, institutionalization and death are frequent consequences of hip fractures. CONCLUSION: The epidemiology of hip fractures is characterized by a high burden of disease, local differences, temporal trends, well-defined high-risk populations and many established risk factors.

[Refresher Orthogeriatrics]. / Orthogeriatrie.

Fragility fractures are associated with a substantial mortality and morbidity. Because of the high prevalence of comorbidities and a high risk of complications the application of geriatric principles in the complex treatment of these patients is vital. The last years have seen a paradigm shift in the treatment of fragility fractures from an orthopedic disorder towards an orthogeriatric syndrome. This article reviews the orthogeriatric principles of treating fragility fractures.

Osteoporotic Pelvic Fractures.

BACKGROUND: The estimated incidence of osteoporotic pelvic fractures among persons over age 60 in Germany is 224 per 100 000 persons per year, and rising. A number of surgical treatment options are available, but clinical long-term data are lacking. METHODS: This review is based on pertinent publications and guidelines retrieved by a selective literature search, and on the authors' clinical experience. RESULTS: Patients often report one or more relatively trivial traumatic incidents leading up to the fracture. They complain of pain in the hip, groin, or lower lumbar region, or of low back pain and sciatica. A new classification scheme entitled Fragility Fractures of the Pelvis (FFP) takes the morphology of the fracture into account and can be used as an aid to therapeutic decision-making (evidence level IV). The goal of treatment is early mobilization with adequate pain relief. Isolated anterior pelvic ring fractures (FFP I) and nondisplaced posterior pelvic ring fractures (FFP II) are usually stable and can be treated conservatively. Type III and IV injuries are unstable and should generally be treated surgically. CONCLUSION: Retrospective analyses have shown that osteoporotic pelvic fractures are associated with decreased mobility and independence and with a one-year mortality ranging from 9.5% to 27%. Prospective therapeutic trials are urgently needed.

Mortality and cardiorespiratory complications in trochanteric femoral fractures: a ten year retrospective analysis.

PURPOSE: Despite intense research and innovations in peri-operative management, a high mortality rate and frequent systemic complications in trochanteric femoral fractures persist. The aim of the present study was to identify predictive factors for mortality and cardio-respiratory complications after different treatment methods in a ten year period at a level I trauma centre. METHODS: Retrospectively, all patients above 60 years of age with trochanteric femoral fracture between January 2000 and May 2011 were analyzed at a level I trauma centre. Demographic variables, comorbidities, and data regarding the surgical procedures, including required transfusions and post-operative complications, were evaluated, and the in-hospital mortality was recorded. The grade of osteoporosis was classified radiographically using the Singh index. RESULTS: The in-hospital mortality rate was 8.2% among 437 patients (male/female ratio = 110/327, mean age = 81 years) with extramedullary open (n = 144), intramedullary (n = 166), and extramedullary minimally invasive (n = 125) procedures. Significant influential factors on in-hospital mortality were identified with binary logistic regression analysis: an age of ≥90 years (P = 0.011), male sex (P = 0.003), a high American Society of Anesthesiologists (ASA) grade (3-5, P = 0.042), and a high osteoporosis grade (Singh index 3-1, P = 0.011). A total of 21.5% of the study population suffered cardio-respiratory complications post-operatively. The specific mortality was 28.7% (P < 0.001), which was influenced by a high ASA grade (3-5, P = 0.002) and a high transfusion rate (P = 0.004). Minimally invasive locked plating was associated with increased cardio-respiratory complications (P = 0.031). CONCLUSIONS: This study identified high patient age, distinctive comorbidities, male sex, and high osteoporosis grade as significant risk factors for increased in-hospital mortality in the treatment of trochanteric femoral fractures. Furthermore, high ASA grade and a liberal transfusion regime led to an increased incidence of cardio-respiratory complications. Patient-specific characteristics, especially osteoporosis grade and pre-existing medical conditions, may assist in the identification of high-risk patients and allow a patient-specific geriatric co-management plan.

[Results of the pilot phase of the Age Trauma Registry DGU®]. / Ergebnisse der Pilotphase des AltersTraumaRegister DGU®.

BACKGROUND: Since 2014, hospitals with ortho-geriatric fracture centres could be certified as AltersTraumaZentrum DGU® in Germany. To measure the quality of treatment in these centres, a geriatric trauma registry (AltersTraumaRegister DGU®) was established. OBJECTIVES: The aim of this work was to report the results of the pilot phase of the AltersTraumaRegister DGU® from the year 2015. MATERIALS AND METHODS: Included were 118 patients >70 years with hip fracture or implant-related femoral fractures. Apart from other parameters, the point of surgery, initiation of anti-osteoporotic treatment and the EQ-5D one week post-surgery was measured. RESULTS: Surgery was performed in 87% of patients within 24 h. Specific osteoporotic therapy could be increased from 4 to 63 patients. The EQ-5D was strongly restricted to one week post-surgery. CONCLUSION: Based on the timing of surgery and anti-osteoporotic therapy, the treatment seems to be successful in the ortho-geriatric fracture centres. For a better evaluation of treatment quality in the AltersTraumaZentren DGU®, implementation of follow-up examinations in the AltersTraumaRegister DGU® is essential.

[Treatment of hip fractures in elderly patients]. / Anästhesie in der Orthopädie†/Unfallchirurgie - Die Versorgung proximaler Femurfrakturen des alten Patienten.

Hip fractures are among the most common fractures in elderly people. The annual number of femoral fractures is even expected to increase because of an aging society. Due to the high number of comorbidities, there are special challenges in treating geriatric hip fracture patients, which require a multidisciplinary management. This includes surgical treatment allowing full weight bearing in the immediate postoperative period, osteoporosis treatment and falls prevention as well as an early ortho-geriatric rehabilitation program.

Numbers of Severely Injured Patients in Germany. A Retrospective Analysis From the DGU (German Society for Trauma Surgery) Trauma Registry.

BACKGROUND: Persons who sustain severe traumatic injury, i.e., those with an Injury Severity Score (ISS) of 16 or above, go on to suffer major physical, emotional, and socio-economic consequences. It is important to know the incidence of severe trauma so that these patients can be cared for optimally. METHODS: Data from the year 2012 on severely injured persons with an ISS of 16 or above were obtained from the trauma registry of the German Society for Trauma Surgery (DGU) and analyzed. Further information was obtained from the database of the DGU trauma network. The annual incidence of severe trauma was estimated from these data in three different ways. RESULTS: An extrapolation of hospital-based data to the German population yielded a figure of 16 742 severely injured persons per year. A population-based estimate from the German federal state of Bavaria yielded a figure of 16 514/year, while an area-based extrapolation using data from 17 established networks yielded a figure of 16 554/year. We added 10% to each of these figures as a correction for assumed underreporting. We conclude that the number of persons who sustained a severe traumatic injury in Germany in 2012 lay between 18 209 (95% confidence interval [CI]: 17 751-18 646) and 18 416 (95% CI: 18 156-18 695). This corresponds to an incidence of 0.02% per year. CONCLUSION: Data from a prospectively maintained nationwide trauma registry were used for the first time to calculate the annual incidence of severe traumatic injury in Germany: the expected number of severely injured persons per year is 18 200-18 400. Previous extrapolations yielded values in the range of 32 500-35 300. A high variability of documentation practices among supraregional trauma centers may have distorted the estimate, along with other factors. The figures were not normalized for age or sex.

Two-Incision Minimally Invasive Approach for the Treatment of Anterior Column Acetabular Fractures.

INTRODUCTION: We describe an alternative to the Letournel ilioinguinal approach for anterior column acetabular fractures that is performed with a unique retraction device that decreases the rate of soft-tissue complications. STEP 1 POSITION THE PATIENT AND IDENTIFY THE SITES FOR THE INCISIONS: Identify the sites for both incisions with the help of an image intensifier. STEP 2 MAKE THE FIRST INCISION TO EXPOSE THE ANTERIOR COLUMN AND THE LINEA TERMINALIS PELVIC BRIM: Make the first incision to expose the central area of the fracture. STEP 3 MAKE THE SECOND INCISION TO EXPOSE THE SYMPHYSIS AND THE IPSILATERAL PUBIC BONE: Make the second incision to expose the area for the distal plate fixation. STEP 4 MAINTAIN EXPOSURE OF THE LINEA TERMINALIS USING A SOFT-TISSUE RETRACTION SYSTEM: For better visualization, use a soft-tissue retraction system. STEP 5 REDUCE THE FRACTURE: Clean and reduce the fracture through the first incision. STEP 6 FIX THE FRACTURE: Perform temporary and definitive fixation according to the standards for anterior acetabular fracture fixation. STEP 7 CLOSE THE WOUND: After radiographic documentation in three views, close the wound. RESULTS: We reported the results of a case-control study of the first twenty-six patients operated on with the two-incision minimally invasive technique.IndicationsContraindicationsPitfalls & Challenges.

The influence of hip rotation on femoral offset in plain radiographs.

BACKGROUND AND PURPOSE: Adequate restoration of femoral offset (FO) is critical for successful outcome after hip arthroplasty or fixation of hip fracture. Previous studies have identified that hip rotation influences the projected femoral offset (FOP) on plain anteroposterior (AP) radiographs, but the precise effect of rotation is unknown. PATIENTS AND METHODS: We developed a novel method of assessing rotation-corrected femoral offset (FORC), tested its clinical application in 222 AP hip radiographs following proximal femoral nailing, and validated it in 25 cases with corresponding computed tomography (CT) scans. RESULTS: The mean FORC was 57 (29-93) mm, which differed significantly (p < 0.001) from the mean FOP 49 (22-65) mm and from the mean femoral offset determined by the standard method: 49 (23-66) mm. FORC correlated closely with femoral offset assessed by CT (FOCT); the Spearman correlation coefficient was 0.94 (95% CI: 0.88-0.97). The intraclass correlation coefficient for the assessment of FORC by AP hip radiographs correlating the repeated measurements of 1 observer and of 2 independent blinded observers was 1.0 and 1.0, respectively. INTERPRETATION: Hip rotation affects the FOP on plain AP radiographs of the hip in a predictable way and should be adequately accounted for.

Less invasive polyaxial locking plate fixation in periprosthetic and peri-implant fractures of the femur--a prospective study of 41 patients.

BACKGROUND: A great variety of methods for the stabilisation of periprosthetic fractures around total hip (THA) or total knee arthroplasty (TKA) have been described. We present the data of our experience in combining a polyaxial, anatomical locking plate with a standardised less invasive technique in the treatment of periprosthetic and peri-implant (femoral nail) femur fractures in this prospective study. PATIENTS AND METHODS: A consecutive series of 41 patients (33 women; age 79.8±11 years) with 41 fractures (n=17 periprosthetic THA, n=10 periprosthetic TKA, n=3 interprosthetic, n=11 perinail) was treated in a 'mini-open' (MO; direct reduction of the fracture and percutaneous plate fixation in two-part fractures; n=22) or a 'minimally invasive' (MI; indirect reduction and percutaneous fixation; n=19) technique. All patients were followed up for 12 months postoperatively. RESULTS: The polyaxial locking mechanism allowed for the setting of a mean of 5.3 screws around an intramedullary implant. Supported by the less invasive strategy, mainly long plates (n=36; 88% were longer than 24cm) were applied without relevant soft-tissue complication. Five surgical revisions (12.1%) had to be performed. During the first postoperative stay, one seroma was evacuated and in two cases the plate broke due to failed biological healing 6 months after the MO technique. In one case, a revision prosthesis had to be implanted due to ligamentous instability, and in another case, soft-tissue balancing of the patella was performed. In the MO group, four of the five complications requiring surgical revision were seen. There was no infection. No statistical difference was seen between the MO and the MI groups for operating room (OR) time and perioperative need for transfusion. In patients with a poor state of health (n=8; immobile and Glasgow Coma Outcome Scale=3), no local complications were seen. All fractures in the peri-implant fracture group (n=11) healed uneventfully. CONCLUSION: Periprosthetic fracture fixation can be performed as part of a standardised less invasive strategy, but the MI technique should be the preferred treatment. The NCB(®) system allows for a stable plate fixation around an intramedullary implant. With the less invasive technique, long plates can be applied with low rates of soft-tissue complication and implant failure.
