J Clin Med 2024; 13:4744. [PMID: 39200885 PMCID: PMC11355065 DOI: 10.3390/jcm13164744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Revised: 08/05/2024] [Accepted: 08/08/2024] [Indexed: 09/02/2024] Open
Abstract
(1) Background: Pelvic fractures, and particularly instabilities of the dorsal pelvic ring, are becoming increasingly prevalent, particularly in orthogeriatric patients. Spino-pelvic triangular osteosynthesis is an effective approach to achieve sufficient stabilization in vertically unstable fractures. This study compares two types of osteosynthesis: the conventional one and a novel instrumentation where the iliosacral screw is placed through a fenestrated iliac screw. (2) Methods: Sixteen artificial osteoporotic L5+pelvis models with an unstable sacral fracture have been instrumented with either an iliac screw connected with a rod to a L5 pedicle screw and an iliosacral screw (TF) or a fenestrated ilium screw connected with a rod to a L5 pedicle screw and an iliosacral screw passing through the fenestra of the iliac screw (TFS). Biomechanical testing was performed using cyclic loading until failure. (3) Results: Both configurations yielded comparable results with regard to initial stiffness, implant loosening, and cycles to failure. The TFS exhibited markedly higher values for cycles to failure and markedly lower values for loosening. However, due to the characteristics of the artificial bone model, these findings were not significant. (4) Conclusions: The novel triangular fixation systems demonstrated comparable results to the standard triangular osteosynthesis configuration.

Abstract
BACKGROUND The growing population of elderly people is leading to a rising number of pelvic ring fractures. These often involve combinations of pubic branch and sacrum fractures, as seen in lateral compression type 1 (LC1) and 2 (LC2) fractures or more precisely classified as fragility fractures of the pelvis (FFP). The combined impact on the anterior and posterior ring brings the risk of prolonged pain, resulting in decreased mobility and increased complications. Given the higher multimorbidity of this population, surgical treatment poses a greater risk of intra- and post-operative complications. Hence, the management and treatment of this particular type of fracture remain challenging. METHODS A retrospective data analysis of 41 patients (F/M; 27/14) treated conservatively for low-energy LC1 or LC2 fractures was performed between 2017 and 2020. The fractures were classified using Rommens' FFP classification. The primary outcome was mobility at 2 and 6 weeks, assessed through chart analysis and phone interviews. To determine factors influencing patient outcomes fracture consolidation was assessed via X-ray analysis. As a secondary outcome logistic regression and decision tree analyzes were conducted. RESULTS The mean age at the time of fracture was 79.8 ± 12.5 (SD) years. Thirty-two patients regained mobility (F/M; 25/7) after 2 weeks. Another 7 patients were mobile after 6 weeks (F/M; 2/5). Two male patients did not regain mobility. Male sex emerged as the sole independent predictor of non-mobility at 2 weeks (p = 0.0037). Age, BMI, pubic branch fracture dislocation >5 mm, analgesic use of opiates, corticosteroid therapy, alcohol and smoking showed no association with mobility recovery. Fracture consolidation was observed in 73.2 % of patients (F/M; 21/9), while one female had no consolidation. Ten patients (F/M; 5/5) were lost to follow-up. CONCLUSIONS Our study shows that LC1 (FFP IIb, IIc) and LC2 (FFP IIIc, IVb) fractures can be effectively treated conservatively, with successful remobilization within 6 weeks. The only independent negative predictor of early mobilization was male sex. Pubic branch displacement >5 mm did not affect the outcome. Therefore, conservative management proves to be a viable option for low-energy LC1 or LC2 fractures. LEVEL OF EVIDENCE IV (retrospective study).

Abstract
(1) Background: Demographic changes over the past decade have had a significant impact on pelvic ring fractures. They have increased dramatically in the orthogeriatric population. Surgeons are faced with implant fixation issues in the treatment of these fragility fractures. This study compares two innovative implants for stabilizing the iliosacral joint in a biomechanical setting. (2) Methods: An iliosacral screw with a preassembled plate allowing the placement of an additional short, angular stable screw in the ilium and a triangular fixation system consisting of a fenestrated ilium screw and an iliosacral screw quasi-statically inserted through the "fenestra" were instrumented in osteoporotic artificial bone models with a simulated Denis zone 1 fracture. Biomechanical testing was performed on a servo-hydraulic testing machine using increasing, synchronous axial and torsional sinusoidal cyclic loading to failure. (3) Results: The SI-Plate and TriFix showed comparable stiffness values. The values for fracture gap angle and screw tip cutout were significantly lower for the TriFix compared to the SI-Plate. In addition, the number of cycles to failure was significantly higher for the TriFix. (4) Conclusions: Implant anchorage and primary stability can be improved in iliosacral instability using the triangular stabilization system.

Abstract
Injuries of the posterior pelvic ring are predominantly associated with osteoporosis. Percutaneously placed screws transfixing the sacroiliac joint have become the gold standard for their treatment. However, screw cut-out, backing-out, and loosening are common complications. One promising option could be cerclage reinforcement of cannulated screw fixations. Therefore, the aim of this study was to evaluate the biomechanical feasibility of posterior pelvic ring injuries fixed with S1 and S2 transsacral screws augmented with cerclage. Twenty-four composite osteoporotic pelvises with posterior sacroiliac joint dislocation were stratified into four groups for S1-S2 transsacral fixation using either (1) fully threaded screws, (2) fully threaded screws with cable cerclage, (3) fully threaded screws with wire cerclage, or (4) partially threaded screws with wire cerclage. All specimens were biomechanically tested under progressively increasing cyclic loading until failure. Intersegmental movements were monitored by motion tracking. The transsacral partially threaded screw fixation with wire cerclage augmentation resulted in significantly less combined angular intersegmental movement in the transverse and coronal plane versus its fully threaded counterpart (p = 0.032), as well as in significantly less flexion versus all other fixations (p ≤ 0.029). Additional cerclage augmentation could be performed intraoperatively to improve the stability of posterior pelvic ring injuries treated with S1-S2 transsacral screw fixation. Further investigations should follow to consolidate the current results on real bones and possibly consider execution of a clinical study.

[PMID: 37833233 DOI: 10.1016/j.injury.2023.111096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 09/27/2023] [Accepted: 10/02/2023] [Indexed: 10/15/2023]
Abstract
There is a growing understanding of the specific characteristics of insufficiency fractures of the pelvis and of general requirements for the treatment of affected patients with focus on early mobilization and effective pain reduction as the main goals of therapy. While there is consensus on the significance of achieving stability of the dorsal pelvic ring structures there is still an open discussion about the potential benefits of additional stabilization of an anterior fracture component. Within a biomechanical test setup, two established methods of dorsal fracture fixation were tested under axial loading (25-1200 N; 1000 test cycles) on an explicit osteoporotic bone model (n = 32) with a standardized FFP type IIIc fracture with and without additional fixation of the anterior fracture component. Dorsal fixation was performed with and long and a short 7.3 mm cannulated screw in S1 in one group (n = 16), and a trans sacral bar with an additional short 7.3 mm cannulated screw in S1 in the other group (n = 16). Half of the samples received a 7.3 mm cannulated retrograde transpubic screw for anterior fixation. The fixation with the trans sacral bar and the additional anterior screw fixation showed the highest rate of stability (p = 0.0014), followed by the double SI-screw fixation with stabilization of the anterior fracture (p = 0.0002). During testing, we observed the occurrence of new sacral fractures contralateral to the initial fracture in 22/32 samples. The results let us assume that stabilization of an additional anterior fracture component relevantly improves the stability of the entire ring construct and might prevent failure of the dorsal stabilization or further fracture progression.

Abstract
Pelvic ring injuries are uncommon but serious injuries. Percutaneous sacro-iliac screw fixation (SSF) is the standard treatment for posterior stabilization of pelvic fractures. Compression forces of the SSF might cause deformity of the sacrum and the pelvic ring. The aim of this radio-volumetric study is to evaluate the morphometry of the sacrum and pelvic ring in SSF for posterior pelvic fractures. (1) Methods: We conducted a radio-volumetric study measuring the bony sacral volume before and after SSF for a pelvic fracture based on a three-dimensional reconstruction of the pre- and postoperative computed tomography scan of 19 patients with a C-type pelvic fracture. In addition to the bony sacral volume, we assessed the pelvic deformity and the load bearing axis. We compared the results of patients without anterior stabilization (Group A) to patients who had additional ORIF of the anterior pelvic ring. (2) Results: Median age of the patients was 41.2 years (±17.8). All patients received percutaneous SSF with partially threaded 7.3 mm screws. The sacral volume decreased from 202.9 to 194.3 cm3 in group A (non-operative treatment anterior, n = 10) and an increase of sacral volume from 229.8 to 250.4 cm3 in group B (anterior ORIF; n = 9). Evaluation of the pelvic deformity also reflected this trend by a decrease of the ipsilateral load-bearing angle in group A (37.0° to 36.4°) and an increase of this angle in group B (36.3 to 39.9°). (3) Conclusions: Bony sacral volume and pelvic deformity after sacro-iliac screw fixation in pelvic fractures depend on treatment of the anterior pelvic ring. Reduction and fixation of the anterior fracture shows an increase of the bony sacral volume and the load bearing angle leading to a closer to normal reconstruction of the pelvic anatomy.

Abstract
BACKGROUND Fracture detection by artificial intelligence and especially Deep Convolutional Neural Networks (DCNN) is a topic of growing interest in current orthopaedic and radiological research. As learning a DCNN usually needs a large amount of training data, mostly frequent fractures as well as conventional X-ray are used. Therefore, less common fractures like acetabular fractures (AF) are underrepresented in the literature. The aim of this pilot study was to establish a DCNN for detection of AF using computer tomography (CT) scans. METHODS Patients with an acetabular fracture were identified from the monocentric consecutive pelvic injury registry at the BG Trauma Center XXX from 01/2003 - 12/2019. All patients with unilateral AF and CT scans available in DICOM-format were included for further processing. All datasets were automatically anonymised and digitally post-processed. Extraction of the relevant region of interests was performed and the technique of data augmentation (DA) was implemented to artificially increase the number of training samples. A DCNN based on Med3D was used for autonomous fracture detection, using global average pooling (GAP) to reduce overfitting. RESULTS From a total of 2,340 patients with a pelvic fracture, 654 patients suffered from an AF. After screening and post-processing of the datasets, a total of 159 datasets were enrolled for training of the algorithm. A random assignment into training datasets (80%) and test datasets (20%) was performed. The technique of bone area extraction, DA and GAP increased the accuracy of fracture detection from 58.8% (native DCNN) up to an accuracy of 82.8% despite the low number of datasets. CONCLUSION The accuracy of fracture detection of our trained DCNN is comparable to published values despite the low number of training datasets. The techniques of bone extraction, DA and GAP are useful for increasing the detection rates of rare fractures by a DCNN. Based on the used DCNN in combination with the described techniques from this pilot study, the possibility of an automatic fracture classification of AF is under investigation in a multicentre study.

Influence of the inclination angle of the S1 pedicle on screw malposition and operative revision in percutaneous iliosacral screw fixation of posterior pelvic ring fractures. Injury 2022; 53:3384-3389.

Abstract
INTRODUCTION Due to aging society, osteoporotic posterior ring fractures of the pelvis are gaining importance. Percutaneous iliosacral screw fixation can reduce pain if conservative therapy is not sufficient. One of the surgical complications is the malposition of the screws in neuroforamen. The aim of this study is to correlate the measured pedicle angle with the screw position in postoperative CT scans. MATERIALS AND METHODS In this retrospective study (level of evidence: III), 97 patients with posterior ring fractures were treated with 137 percutaneous iliosacral screws. The inclination angles of the S1 pedicle were measured in the preoperative pelvic CT scan of each patient. Patients were divided up into pedicle angles from 10 - 19.9° (Group 1), 20 - 29.9° (Group 2), 30 - 39.9° (Group 3) and 40 - 49.9° (Group 4). We correlated the pedicle inclination angle to radiologically described screw position in the L5/S1 neuroforamen and the need for revision because of screw malposition. RESULTS A total of 10 pedicle inclination angles were from 10 - 19.9° (7.3%), 96 from 20 - 29.9° (70.1%), 28 from 30 - 39.9° (20.4%) and three from 40 - 49.9° (2.2%). Of the 137 screws used, 19 were intraforaminal (13.9%). There were no intraforaminal screws in the Group 1, eight in Group 2, 10 in Group 3 and one in Group 4. Five of the screws needed revision (3,6%). There were no revisions in Groups 1 and 4, two in Group 2 and three in Group 3. Groups 3 and 4 had a higher percentage of intraforaminal screw positions. Patients with steeper angles S1 pedicles showed a significantly higher probability of intraforaminal screw location and revision (p<0.01). DISCUSSION Complications such as intraforaminal screw position and revision surgery are more frequent in patients with steeper S1 pedicles, making this a detrimental prognostic marker.

Abstract
BACKGROUND Fragility fractures of the pelvis (FFP) encompass two fracture entities: fracture after low-energy trauma and insufficiency fracture without trauma. It is unclear whether the two subgroups differ in terms of diagnosis and therapy. The aim of this retrospective study was to evaluate insufficiency fractures with regard to defined parameters and to compare specific parameters with the fractures after low-energy trauma. PATIENTS AND METHODS In the period from 2008 to 2017, 203 patients with FFP were recorded at our clinic (Level 1 Trauma Centre DGU, SAV approval). Of these, 25 had an insufficiency fracture and 178 had a pelvic ring fracture after low-energy trauma. Epidemiological, diagnostic and therapeutic parameters were examined. RESULTS There was a relative increase in the insufficiency fracture within the FFP (2008 - 2009: 5.0% vs. 2015 - 2017: 17.8%). In these patients, osteoporosis tended to be more pronounced than in patients after low-energy trauma (t-value: - 3.66 vs. - 3.13). The diagnosis of insufficiency fractures showed increased use of MRI and DECT (60.9% vs. 26.0%) and a high proportion of type IV fractures after FFP (40.0% vs. 7.9%). In terms of therapy, surgical treatment of the insufficiency fracture was sought more often (68,2% vs. 52,1%), with a tendency towards increased use of combined osteosynthesis procedures (14.3% vs. 7.6%). CONCLUSION We were able to show that as the number of cases increases, the insufficiency fracture becomes more important within FFP. If these patients tend to have more pronounced osteoporosis, particular attention should be paid to the diagnosis and adequate therapy of the osteoporosis, especially in the case of an insufficiency fracture. In addition to the increased diagnostic testing using MRI and DECT to detect oedema and the increased surgical therapy for this type of fracture, it is also noteworthy that the insufficiency fracture can cause higher-grade fractures after FFP.

[PMID: 34554141 PMCID: PMC9038250 DOI: 10.1097/ta.0000000000003398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 08/23/2021] [Accepted: 08/31/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Increasing life expectancy has led to higher incidence of fragility fractures of the pelvis. These demographic changes may have a direct impact on fracture patterns. The goal of this study was (1) to evaluate demographical trends in patients with pelvic ring injuries at a tertiary Swiss trauma center and (2) to analyze the influence on fracture patterns. METHODS We performed a retrospective cross-sectional study including 958 patients (mean ± SD age, 57 ± 21 years; 48% women) with a pelvic ring injury between 2007 and 2017. Fractures were classified according to Tile, Young and Burgess or Rommens and Hofmann (fragility fractures) using conventional and computer tomography imaging. Low-energy fractures were defined as fractures resulting from fall from standing height or less. Fracture classifications, age, sex, Injury Severity Score, and trauma mechanism were compared using analysis of variance or χ2 test. Cluster analysis was performed to identify groups with similarities in fracture patterns and demographic parameters. RESULTS From 2007 to 2017, the frequency of pelvic ring injuries increased by 115% (increase per decade), and mean age increased by 15% (p = 0.031). A trimodal age distribution was found; highest increase for fractures occurred in the older (265%) patient group. Low-energy fracture was the most common trauma mechanism (43% of all fractures, an increase of 249%). Changes in fracture pattern showed a disproportioned increase of lateral compression (LC) fractures (LC type 1 in 64%) or partially stable fracture (B2, with 39%). In patient older than 65 years, the strongest increase was found for nondisplaced posterior fractures with an overall prevalence of 62%. Five clusters were found with the most frequent cluster representing older female patients with low-energy fracture (LC, Tile type B) in 30%. CONCLUSION The current results corroborate the trend of increasing frequency of fragility fractures in an aging society. The demographic shift has a direct impact on fracture pattern with a disproportionate increase in partially stable compression fracture of the pelvis. LEVEL OF EVIDENCE Prognostic/Epidemiologic, Level III.

Abstract
Introduction Previous studies illustrate significant increases in pelvic fracture incidence; however, there is a paucity of information on the incidence of osteoporotic pelvic ring injuries based on large-scale examinations of geographically and ethnically diverse populations. This study addresses the epidemiology of osteoporotic pubic ramus fractures in the United States and details differences in incidence rates with respect to age, gender, and race. Materials and Methods National Electronic Injury Surveillance System (NEISS) data between 2002 and 2019 was gathered for individuals aged 60 and above presenting to U.S. emergency departments with ramus fractures. Incidence rates for ramus injuries were calculated using adjusted U.S. Census Bureau estimates of population. Fracture incidences were calculated for age, gender, and race strata. Results The overall incidence rate of pubic ramus fractures in the United States between 2002 and 2019 was 13.47 per 1,000,000 people 60 years and older (95% confidence limit: 9.92-17.01). The incidence of pubic ramus fractures for females in the US was 21.71 (16.08-27.34). Rates of ramus fracture increased overall (P < .001) and for both genders between the ages of 60 and 100, though the rate increase was significantly greater in females than in males (P < .001). In terms of race, incidence was highest Asian females and lowest in Native American and Pacific Islander men. Discussion/Conclusion : As the first national study addressing the epidemiology of ramus injuries in the United States, this work reveals these injuries comprise a significant fracture risk in the elderly. In addition, it highlights gender and ethnic strata that are more susceptible to these injuries.

The grade of instability in fragility fractures of the pelvis correlates with impaired early mobilization. Eur J Trauma Emerg Surg 2022; 48:4053-4060. [PMID: 35279755 PMCID: PMC9532290 DOI: 10.1007/s00068-022-01933-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 02/20/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE This study aimed to investigate whether gait patterns of patients with fragility fractures of the pelvis (FFP) comply with the grade of fracture instability, defined by radiological patterns. PATIENTS AND METHODS This prospective, single-center, observational study included 39 patients with an FFP. Gait analysis was performed with a wearable insole force sensor (Loadsol® by Novel, Munich, Germany) 4-7 days after admission. Patients were divided in two groups: Group A included FFP type 1 fractures, which affect the anterior pelvic ring only, Group B contained FFP type 2-4 fractures with an involvement of the posterior pelvic ring. Primary outcome parameter was the FTI ratio (force-time integral (N*s)). RESULTS The mean age was 85.08 years (SD ± 6.45), 94.9% (37/39) of the patients were female. The most common fracture type was an FFP 2b (64.1%, 25/39). Group A showed a significantly higher FTI ratio (45.12%, SD ± 4.19%) than Group B (38.45%, SD ± 5.97%, p = 0.002). Further, a significant correlation of the FTI ratio and the average (r = 0.570, p < 0.001) and maximum (r = 0.394, p = 0.013) peak force was observed. CONCLUSION The gait pattern of patients with an FFP type 2-4 was more imbalanced than of patients with an FFP type 1 fracture. These findings match with the radiological classification of FFP, which indicates higher instability, when the posterior pelvis is affected. Gait analysis might offer earlier functional diagnostics and may accelerate the treatment decision with shorter periods of immobility in future. Especially in cross-border cases, early gait analysis could be beneficial to clarify the indication for or against surgery.

Abstract
The routine care of osteoporotic fractures of the pelvic ring requires a well-structured treatment algorithm in order to start a stage-appropriate treatment without delay. Nowadays, minimally invasive treatment methods are the gold standard. The minimally invasive dorsal techniques primarily include percutaneous sacroiliac screw osteosynthesis and internal spinopelvic fixation. For minimally invasive treatment from an anterior approach the subcutaneous internal fixator is the method of choice. The primary goal of all forms of treatment, whether conservative or surgical, is the quickest possible painless mobilization and transfer to the familiar environment.

Abstract
Background The incidence of osteoporotic pelvic fractures in elderly patient is rising. This brings an increasing burden on health and social care systems as these injuries often lead to prolonged hospital admissions, loss of independence, morbidity and mortality. Some centres now advocate stabilisation of these injuries to reduce pain, facilitate early mobilisation, decrease hospital stay and restore independence. A systematic review of the literature was planned to establish the evidence for this intervention. Methods A systematic review was performed according to PRISMA guidelines. A clinical librarian performed a search of the following databases: NHS Evidence, TRIP, the Cochrane Database of Systematic Reviews, MEDLINE and EMBASE. Seventeen eligible studies were identified with 766 patients. Results The quality of evidence was poor with no good quality randomised trials. The majority of injuries were minimally displaced. Posterior ring injuries were most often stabilised with percutaneous screws which were sometimes augmented with void filler. A number of techniques were described for stabilisation of the anterior ring although fixation of the anterior ring was frequently not performed. There was consistent evidence from the included studies that operative intervention significantly improved pain. Complications were minimal but there were increased failure rates when a single unaugmented sacroiliac joint screw was used. The limited availability of non-operative comparators made it difficult to draw firm conclusions about the efficacy of surgical over non-surgical management in these patients. Conclusions Operative management of fragility fractures of the pelvis should be considered for patients failing a brief period of non-operative management, however prospective randomised trials need to be performed to provide improved evidence for this intervention. Surgeons should consider which fixation techniques for fragility fractures of the pelvis are robust enough to allow immediate weightbearing, whilst minimising operative morbidity and post-operative complications.

Abstract
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.

Abstract
Background: More than 750,000 fragility fractures occur in Germany every year, with an expected increase in the following years. Interdisciplinary care pathways for geriatric patients are increasingly established to improve the treatment process and outcome, but there has been only limited evaluation of their use. Objectives: This study aimed to compare patient care before and after the implementation of a geriatric trauma center (GTC) in conformity with the German Society for Trauma Surgery (DGU®). Patients and Methods: We performed a retrospective single-center cohort study, including 361 patients >70 years old with lumbar spine, pelvic, and acetabular fractures, admitted between January 2012 and September 2019. Patients were divided into a usual care cohort (UC, n = 137) before implementation and an ortho-geriatric care cohort (OGC, n = 224) after implementation of the GTC DGU®. We recorded and compared demographic data, fracture type, geriatric assessment and management, therapy, complications, and various clinical parameters, e.g., length of stay, time to surgery, hours admitted to ICU, and change in walking ability. Results: The geriatric assessment revealed significant geriatric co-morbidities and a need for geriatric intervention in 75% of the patients. With orthogeriatric co-management, a significant increase in the detection of urological complications (UC: 25.5% vs. OGC: 37.5%; p = 0.021), earlier postoperative mobilization (UC: 57.1% vs. OGC: 86.3%; p < 0.001), an increased prescription of anti-osteoporotic treatment at discharge (UC: 13.1% vs. OGC: 46.8%; p < 0.001), and lower rates of revision surgery (UC: 5.8% vs. OGC: 3.1%; p = 0.012) could be seen. Conclusions: Our results emphasize the improvement in patient care and clinical outcome by implementing a GTC DGU® and provide opportunities for future improvement in ortho-geriatric patient care.

Abstract
The aim of this review is to summarise the current concepts in the management of acetabular fractures in the elderly population. A literature review of the evidence regarding the management of elderly acetabular fractures was performed utilising PubMed and Ovid. The predominant causes and fracture patterns of acetabular fractures are changing as populations age. Consequently, the operative management has had to change also. Judet and LeTournel did not offer operative treatment to any patients older than sixty. However, in the present time, according to the German Pelvic Registry, over half the patients aged sixty or over, sustaining acetabular fractures underwent operative fixation. We find that the increasing age of the population raises particular challenges for the operating surgeon. Postoperative rehabilitation should be focused on early mobilisation. More research needs to be focussed on standardised treatment protocols and long-term outcomes for this cohort of patients.

Abstract
BACKGROUND Pelvic fractures are typical for frail geriatric patients. They are characterized by increasing pain and loss of mobility. As geriatric pelvic fractures differ from the typical high velocity injuries, Rommens and Hofmann recommended a new classification for fragility fractures of the pelvis (FFP) in 2013. In addition to the location of the fracture they also assessed the degree of dislocation. OBJECTIVE Compared to known fracture classifications of the pelvis, the FFP classification appears complex. Therefore, this study was designed to investigate the interobserver reliability of the FFP classification. MATERIAL AND METHODS The members of the Section of Geriatric Traumatology (DGOU) were presented with 10 DICOM data sets with fractures of the pelvis for classification. As a reference the classification of P.M. Rommens, the author of the FFP, was established. RESULTS In this study 24 consultants (47%) and 27 (53%) residents took part. Also, six radiologists were invited to participate. A total of 493 assessments were made. In 184 (37%) cases there was agreement with the reference, in 183 (37%) computed tomography images the fractures were classified lower, in 26 (26%) higher than the reference. This initially resulted in a Cohens κ coefficient of 0.36. This corresponds to a sufficient agreement (fair) according to Garbuz. With the reduction of the classification to four main groups, the Cohens κ coefficient increased to a satisfactory value. CONCLUSION The reasons for the partly low agreement could be the participants' lack of experience and an inaccurate description of the classification levels. In the end, however, the FFP classification is the only one that meaningfully represents pelvic fractures of geriatric and frail patients. By simplifying to the four main groups, a better interobserver reliability is achieved. For a successful treatment, however, attention to the individual patient and the "fracture personality" is essential.

Abstract
BACKGROUND Identifying patients with maladaptive fear of falling (FOF) is important in the rehabilitation phase after serious fall. The 6-item Fear of Falling Questionnaire-revised (FFQ-R) was seen as promising measurement instrument as it evaluates FOF in a broader way than the one-item-question and independent of physical activities. AIM The purpose of the analysis was to evaluate the psychometric properties of the translated German FFQ-R. METHODS Back-translation method was applied. Confirmatory factor analysis (CFA) with diagonally weighted least square estimation was used to verify the two-factor structure. Data were collected during inpatient rehabilitation from hip and pelvic fracture patients [age 84.3 ± 6.2, Mini-Mental State Examination (MMSE) scores > 23] participating in an RCT (N = 112) and a cross-sectional survey (N = 40). RESULTS Internal consistency was 0.78 (Cronbach´s alpha). No floor or ceiling effects were found. Discriminatory power on item level was moderate to good (r = 0.43-0.65). CFA revealed a good model fit and confirmed the two-factor structure. The German FFQ-R was moderately correlated (r = 0.51) with the Short Falls Efficacy Scale-International (Short FES-I) used as a proxy measure for FOF. Missing rates up to 9% for specific items were because some individuals, independent of cognitive level or age, had problems to rate items with conditional statements on possible negative consequences of a fall. CONCLUSIONS Results demonstrated moderate to good psychometric properties similar to the original English version in a comparable sample of fracture patients.

Abstract
BACKGROUND Pelvic ring fractures type C present a special challenge due to their high instability, the possible accompanying injuries and the high mortality rate of up to 18.9%. The aim of this retrospective analysis was to use the data from the DGU pelvic register to identify changes in the epidemiology and therapy for type C pelvic ring fractures between 2004 and 2014. MATERIALS AND METHODS 2,042 patients with type C pelvic ring injury were retrospectively included. Three time periods with roughly equal patient groups were specified and differences in epidemiology and the type of therapy were evaluated. For the surgical cases, the time of the operation, the duration of the operation, blood loss, the location of the fracture and the type of osteosynthesis were evaluated and the reduction result was recorded. RESULTS For the period under review, there is an age shift in the incidence of a type C pelvic ring fracture towards older age. The isolated pelvic injury has increased, while the proportion of pelvic injuries in the context of polytrauma has steadily decreased. Complications and mortality decreased as a percentage. The tendency towards minimally invasive procedures could be shown in the surgical care. Navigated procedures in the area of the pelvic ring have so far not proven successful. CONCLUSIONS We were able to show that the majority of the patients are increasingly old, that there is no relevant trauma in the history and that there is an increase in the isolated pelvic fracture type C and a decrease in the number of polytraumatised or multiply injured patients. In conjunction with mortality from pelvic ring injuries, the successes of standardised, pelvic-specific emergency management, an adapted time of operation outside the vulnerable phase and stable osteosynthesis care, which enable early functional follow-up treatment, are also evident.

Abstract
INTRODUCTION Spinopelvic instability is common in type IV fragility fractures of the pelvic ring (FFP) and type C traumatic pelvic fractures. This results in the indications for operative stabilization using a spinopelvic support. Due to the variety of surgical techniques for spinopelvic support it is unclear what importance a minimally invasive spinopelvic screw-rod osteosynthesis can have. MATERIAL AND METHODS In the retrospective clinical study over a period of 2 years, 23 patients (median age 67 years, 5 male and 18 female) with unstable pelvic fractures (FFP type IV: n = 12, AO/OTA type C: n = 11) treated by triangular minimally invasive spinopelvic stabilization (TMSS) were included in the study. The patient data were examined with respect to the parameters gender, age, fracture morphology, intraoperative blood loss, operating time, postoperative infection, postoperative reduction result in the computed tomography (CT) imaging and screw loosening. RESULTS The average age of the 11 type C fractures was 43 years and that of the 12 FFP type IV fractures was 80 years. The follow-up period was on average 12.2 months. The average operation time was 67 min, the blood loss was 70 ml, there were 2 postoperative infections and 4 cases of screw loosening. The reduction according to Matta was < 4 mm for all FFP and between 4-20 mm for traumatic pelvic fractures. Symptomatic pseudarthroses occurred in 3 cases. CONCLUSION The triangular minimally invasive spinopelvic stabilization (TMSS) showed a stable and sufficient treatment of the type IV fragility fractures and in the slightly displaced type C traumatic pelvic fractures. Coarse fracture dislocations limit the procedure.

Abstract
This is a monocentric, retrospective study to analyze radiological findings as well as perioperative and postoperative complications in patients who underwent percutaneous triangular stabilization of type 3 and type 4 fragility fractures of the pelvis. From August 2017 to December 2018, 20 patients were treated surgically. Thirteen patients (65%) were followed-up and received a CT scan of the pelvis after an average time of 14.8 months. A total of 5 patients (38%) had to undergo revision surgery, 2 patients (15%) immediately, 3 patients (23%) in the interval. In 84.6% no fracture line was visible in the sacrum. Fracture healing of the anterior pelvic ring was observed in all cases. Our results show that percutaneous triangular stabilization of type 3 and type 4 fragility fractures of the pelvis usually leads to fracture healing. Radiological signs of loosening were observed in 62%, an implant removal due to symptomatic loosening was necessary in 23%.

Abstract
BACKGROUND Increasing numbers of unstable pelvic ring fractures, due to the ongoing demographic change and improvements in the rescue of high-energy traumatic events, are challenging trauma and orthopedic surgeons. While initial installation of an external fixation device is often necessary, placement of iliac crest pins can be difficult due to the complex osteology of the ilium. HYPOTHESIS We aim to analyze (1) the length, localization and angulation of the iliac pillar and (2) to define the dimensions of the surgical corridor for a better understanding of pin entry point and trajectory, thus preventing shortcomings in anterior external fixation of pelvic ring injuries. METHODS Twenty hemipelvises from 10 fresh-frozen cadaveric torsos (3 female, 7 males; mean age 80.2 years) were harvested. The following measurements were taken with digital calipers: Location of the iliac pillar in relation to the anterior superior iliac spine and to the acetabulum roof, mean length and diameter of the iliac pillar, maximum diameter of the iliac pillar. In addition we measured the width of the different bone layers. RESULTS The mean length of the hourglass shaped iliac pillar was 107.04mm with a mean width of 17.0mm (min. 15.1; max. 19.2). The mean distance to the anterior superior iliac spine was 69.00mm (min. 64.8; max. 73.4). The mean maximum width of the iliac pillar was 12.16mm (min. 9.4; max. 13.8). Caudally the line describing the iliac pillar intercepts the cranial acetabular rim at 12 o'clock. The smallest mean diameter of the cancellous bone was 7.5mm±2.0. CONCLUSION The iliac pillar is part of the complex osteology of the human pelvis. A cohesive description of its location and dimensions has been lacking. Successful treatment of pelvic fracture depends on an optimal preoperative planning, accurate overall reduction, and stable fixation. We described the origin and angulation to provide a good bone stock for external fixation pin and the width of the different bone layers. This study therefore contributes by facilitating a thorough understanding of pelvic osteology and describing the location and dimensions of an optimal osseous pathway. LEVEL OF EVIDENCE Anatomical descriptive study.

Abstract
PURPOSE OF REVIEW Fractures of osteoporotic bone in elderly individuals need special attention. This manuscript reviews the current strategies to provide sufficient fracture fixation stability with a particular focus on fractures that frequently occur in elderly individuals with osteoporosis and require full load-bearing capacity, i.e., pelvis, hip, ankle, and peri-implant fractures. RECENT FINDINGS Elderly individuals benefit immensely from immediate mobilization after fracture and thus require stable fracture fixation that allows immediate post-operative weight-bearing. However, osteoporotic bone has decreased holding capacity for metallic implants and is thus associated with a considerable fracture fixation failure rate both short term and long term. Modern implant technologies with dedicated modifications provide sufficient mechanical stability to allow immediate weight-bearing for elderly individuals. Depending on fracture location and fracture severity, various options are available to reinforce or augment standard fracture fixation systems. Correct application of the basic principles of fracture fixation and the use of modern implant technologies enables mechanically stable fracture fixation that allows early weight-bearing and results in timely fracture healing even in patients with osteoporosis.

Abstract
The number of low energy traumas in older people with subsequent pelvic ring fractures is increasing in contrast to high energy traumas with pelvic injury in younger people. Geriatric pelvic fractures can be treated conservatively with analgesics and physiotherapy-assisted mobilization, depending on the symptoms. If physical complaints do not allow adequate mobilization, surgical stabilization is indicated. It is often possible to stabilize the dorsal pelvic ring with transiliosacral screws. If additional instability associated with anterior pelvic ring complaints is prevalent, stabilization of the anterior ring can be achieved by invasive osteosynthesis using a plate or percutaneously by implanting an intramedullary plastic polymer.

Abstract
Abstract
Introduction Isolated pelvic fractures are relatively rare with an incidence of 3 – 6% of all fractures, but their incidence in polytraumatized individuals increases to 25%. The S3 guideline Polytrauma gives a clear recommendation for diagnostics by means of pelvic radiography (X-ray) and computed tomography (CT). A recommendation for the diagnosis by means of magnetic resonance tomography (MRI) especially in patients with low energetic/missing trauma does not currently exist. It is unclear on the basis of which criteria the MRI can be indicated in pelvic fractures. The aim of our study was therefore to retrospectively record indications for the indication of MRI in pelvic fractures – with adequate as well as inadequate trauma.
Material and Methods In a retrospective clinical study, a total of 140 patients (median 68 years, range 15 – 97, 75 female, and 66 male) with a pelvic fracture were included in the study over a period of three years. Overall, the trauma mechanism revealed 73 adequate and 67 inadequate fractures. 31/140 patients had undergone MRI of the pelvis in addition to a CT/X-ray scan. The two subgroups “with MRI” and “without MRI” were analyzed with regard to the parameters “sex”, “age”, “adequacy of the trauma”, “fracture localization”, “duration of admission to imaging”, “type of therapy” and “duration to surgery” compared.
Results It was shown that the MRI diagnosis was performed especially in female, elderly patients (81 years, range 19 – 94 years). Patients with inappropriate trauma have received MRI more frequently (74%) than patients with adequate trauma (26%). With regard to fracture localization no differences could be shown. The MRI was performed on a median 4 days after the CT examination. Regarding the decision “conservative” vs. “operationally” our two groups without and with MRT tended to differ not. Patients with MRI were operated on median 2 days later than patients who did not receive MRI.
Conclusions Pelvic fracture MRI should be performed primarily in elderly female patients without adequate trauma. In patients with adequate trauma, MRI is of low value, especially as MRI diagnostics are performed with delay, resulting in later surgery.

Abstract
Fractures of the extremities in the elderly constitute more than two-thirds of all fragility fractures befalling frail, osteoporotic and sarcopenic patients. Although treatment controversies abound, consensus exists. Upper extremity fractures hinder activities of daily living and are debilitating. Open fractures or displaced fractures will need surgical intervention. Wrist fractures treated operatively allow early use of the hand. Most pelvic fractures are treated conservatively. In the lower extremities, fractures of the long bones, tibia and femur need surgical intervention. Non-displaced fractures around the foot may be treated with immobilisation and avoidance of full weight-bearing. As a rule, fractures take four months for consolidation. Individually tailored solutions are needed for frail patients with comorbidities. Maintaining joint mobility and muscle strength preserves mobility and autonomy. Caring for extremities trauma is team work, involving family and health care providers. Prevention efforts are mandatory.

Abstract
AIM With the predicted demographic change, the treatment of geriatric patients will become a major issue for health systems worldwide. The majority of pelvic ring fractures occur in older adults, and their treatment might be associated with a distinct mortality. Herein, we analyzed the data of 5665 patients with pelvic ring fractures aged ≥60 years included in the German Pelvic Trauma Registry from 1991 to 2013. METHODS The data were collected prospectively, multicentrically in hospitals participating in the German Pelvic Trauma Registry. Demographic data were retrospectively analyzed, stratified for age, sex, type of injury, mode of therapy, injury severity score (ISS) and mortality. RESULTS The overall mortality decreased over the 22-year study period from 9.3% to 3.8% (P < 0.05), whereas the median ISS significantly increased. During the observation period, mortality was higher in patients with type B and, particularly, type C fractures when compared with patients with type A fractures. Mortality rates of patients aged >80 years did not significantly differ from those aged >60 or >70 years. Male patients showed a significantly higher mortality compared with female patients, as well as a significantly higher median ISS. The mortality rate of patients with surgically-treated type C fractures decreased over the study period from 35.7% to 6.9% (P < 0.05). CONCLUSIONS Over the past two decades, the mortality of older patients after pelvic ring fractures has significantly decreased. The higher overall mortality rate of male patients might mainly be accounted for by the relatively higher fraction of type C fractures and a higher ISS. Geriatr Gerontol Int 2019; 19: 24-29.

Abstract
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.
