Abstract
OBJECT A novel technique, percutaneous elastic stable intramedullary nail fixation (ESIN), proposed by our team for the treatment of anterior pelvic ring injury. Finite element analysis and retrospective case-control study were used to compare biomechanical properties and clinical outcomes between ESIN and other techniques. METHODS Four groups of finite element models of pelvic anterior ring injury were simulated, including ESIN (model A), retrograde transpubic screw fixation (RTSF, model B), subcutaneous internal fixator (model C), and external fixator (model D), and a vertical downward load of 500 N was applied to the S1 vertebral endplate. Stress and displacement distributions of intact pelvis, displacement distributions of pubic fracture fragments, and stress distributions of fixation devices were analysed. Then 31 patients with anterior pelvic ring injury (15 in the ESIN group and 16 in the RTSF group) were reviewed. Clinical outcomes were evaluated at the final follow-up. Postoperative complications were also recorded. RESULTS Under 500N loading, the intact stability of the pelvis was compared as follows: model B (20.58 mm, 121.82 MPa), model A (20.80 mm, 129.97 MPa), model C (22.02 mm, 141.70 MPa), and model D (22.57 mm, 147.06 MPa). The regional stability of superior pubic ramus was compared as follows: model B (9.48 mm), model A (10.16 mm), model C (10.52 mm), and model D (10.76 mm). All 31 patients received follow-up at least 12 months postsurgery (range 12-20 months). Age, sex, injury mechanism, fracture type, time between the injury and operation, American Society of Anesthesiologists score, intraoperative blood loss, hospital stay, follow-up period, time to union, and Majeed scores did not differ significantly between the two groups ( P >0.05). However, the differences in the duration of unilateral surgery, unilateral intraoperative fluoroscopy and one-time success rate were significant ( P <0.05). CONCLUSIONS With sufficient biomechanical stability and minimally invasive advantage, the percutaneous technique using ESIN can be used to successfully treat anterior pelvic ring injuries. In addition, advantages over RTSF include a shorter duration of surgery, reduced requirement for intraoperative fluoroscopy, and a higher one-time success rate. ESIN therefore constitutes a good alternative to RTSF.

SAGE Open Med 2024; 12:20503121241236132. [PMID: 38465240 PMCID: PMC10924554 DOI: 10.1177/20503121241236132] [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: 08/02/2023] [Accepted: 02/09/2024] [Indexed: 03/12/2024] Open
Abstract
Introduction Fragility fractures are a large source of morbidity and mortality in the elderly. Orthopaedic surgeons are regularly the main point of contact in patients with lateral compression type 1 pelvis fractures, despite many of these being treated non-operatively. This study aims to identify risk factors for mortality and elucidate which follow-up visits have the potential to improve care for these patients. Methods and materials In all, 211 patients have been identified with fragility lateral compression type 1 fractures at a level 1 trauma centre over a 5-year period. For all patients, we recorded patient demographics, imaging data, hospital readmissions, medical complications and death dates if applicable. Results Of the 211 patients identified, 56.4% had at least one orthopaedic follow-up, of which no patient had a clinically meaningful medical intervention initiated. 30-day readmission rate was 19%, and 1-year mortality was 24%. Male sex, need for an assist device, higher Charlson Comorbidity Index and increased age were found to be statistically associated with increased risk of mortality. Patients who followed up with their primary care physician were found to have a statistically lower risk of mortality. Computed tomography scans were obtained in 70% of patients and never limited patient weight-bearing status or found any additional injury not already identified on the radiograph. Discussion/Conclusions For patients with lateral compression type 1 type fragility fractures, orthopaedic surgeons did not offer additional clinically meaningful intervention after the time of initial diagnosis in this patient cohort. The rate of clinical follow-up with a primary care physician is relatively low despite high rates of medical comorbidity. Computed tomography scans were utilised frequently but did not change recommendations. The high rate of medical complications and lack of orthopaedic intervention suggest that we should re-evaluate the role of the orthopaedic surgeon versus the primary care physician as the primary point of medical contact for patients with these injuries.

Abstract
Background Lateral compression type-1 pelvic fractures are a common fragility fracture in older adults. Patients who do not mobilise due to ongoing pain are at greater risk of immobility-related complications. Standard treatment in the United Kingdom is provision of pain relief and early mobilisation, unlike fragility hip fractures, which are usually treated surgically based on evidence that early surgery is associated with better outcomes. Currently there is no evidence on whether patients with lateral compression type-1 fragility fractures would have a better recovery with surgery than non-surgical management. Objectives To assess the clinical and cost effectiveness of surgical fixation with internal fixation device compared to non-surgical management of lateral compression type-1 fragility fractures in older adults. Design Pragmatic, randomised controlled superiority trial, with 12-month internal pilot; target sample size was 600 participants. Participants were randomised between surgical and non-surgical management (1 : 1 allocation ratio). An economic evaluation was planned. Setting UK Major Trauma Centres. Participants Patients aged 60 years or older with a lateral compression type-1 pelvic fracture, arising from a low-energy fall and unable to mobilise independently to a distance of 3 m and back due to pelvic pain 72 hours after injury. Interventions Internal fixation device surgical fixation and non-surgical management. Participants, surgeons and outcome assessors were not blinded to treatment allocation. Main outcome measures Primary outcome - average patient health-related quality of life, over 6 months, assessed by the EuroQol-5 Dimensions, five-level version utility score. Secondary outcomes (over the 6 months following injury) - self-rated health, physical function, mental health, pain, delirium, displacement of pelvis, mortality, complications and adverse events, and resource use data for the economic evaluation. Results The trial closed early, at the end of the internal pilot, due to low recruitment. The internal pilot was undertaken in two separate phases because of a pause in recruitment due to the coronavirus disease 2019 pandemic. The planned statistical and health economic analyses were not conducted. Outcome data were summarised descriptively. Eleven sites opened for recruitment for a combined total of 92 months. Three-hundred and sixteen patients were assessed for eligibility, of whom 43 were eligible (13.6%). The main reason for ineligibility was that the patient was able to mobilise independently to 3 m and back (n = 161). Of the 43 eligible participants, 36 (83.7%) were approached for consent, of whom 11 (30.6%) provided consent. The most common reason for eligible patients not consenting to take part was that they were unwilling to be randomised to a treatment (n = 10). There were 11 participants, 5 randomised to surgical management with internal fixation device and 6 to non-surgical management. The average age of participants was 83.0 years (interquartile range 76.0, 89.0) and the EuroQol-5 Dimensions, five-level version utility score at 6 months post randomisation (n = 8) was 0.32 (standard deviation 0.37). A limitation of the trial was that study objectives were not addressed due to poor recruitment. Conclusions It was not feasible to recruit to this trial in the current context. Further research to understand the treatment and recovery pathways of this group of patients, along with their outcomes, would be needed prior to undertaking a future trial. Future work Exploration of equipoise across different healthcare professional groups. Investigate longer-term patient outcomes. Trial registration This trial is registered as ISRCTN16478561.

EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:1073-1078. [PMID: 37932481 DOI: 10.1007/s00590-023-03775-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 10/24/2023] [Indexed: 11/08/2023]
Abstract
PURPOSE To determine the incidence of nonunion, clinical and radiological outcomes, and risk factors for nonunion in conservatively treated pubic ramus fractures among patients diagnosed with pelvic ring injury. METHODS A total of 546 patients (192 men, 354 women) diagnosed with pubic ramus fracture, treated conservatively, and who had completed > 1 year follow-up at three level 1 trauma centers between January 2014 and December 2020, were enrolled. Clinical and radiological evaluations were compared between union and nonunion groups. Logistic regression and Kaplan-Meier analyses were used. RESULT At the final follow-up, 527 (96.5%) and 19 (3.5%) patients had union and nonunion of fractures, respectively. The union and nonunion groups exhibited statistically significant differences in posterior injury (p = 0.040), bilateral ramus fracture (p < 0.001), initial displacement (p < 0.001), and clinical result (p < 0.001). In the multivariate logistic regression analysis, initial displacement (odds ratio, 4.727; p = 0.005) was analyzed as a risk factor for nonunion. According to the Kaplan-Meier analysis, the median initial displacement of nonunion occurrence was 17.9 mm (standard error, 1.211; 95% confidence interval 15.526-20.274), and nonunion patients were included if the displacement was > 15.9 mm (standard error, 1.305) on the 75th percentile. CONCLUSION Conservative treatment is ineffective in some ramus fracture cases with pelvic ring injury. As ramus nonunion causes functional deterioration, active treatment is required if the displacement is ≥ 16 mm.

Posterior pelvic ring involvement detected with CT taken within a week of admission in acute fragility fractures of the pelvis (FFP) does not predict failure of conservative treatment: a retrospective cohort study. BMC Musculoskelet Disord 2023; 24:320. [PMID: 37087474 PMCID: PMC10122380 DOI: 10.1186/s12891-023-06439-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 04/18/2023] [Indexed: 04/24/2023] Open
Abstract
BACKGROUND Acute low energy pubic rami fractures in the elderly receive primarily conservative treatment. There is debate to what extent posterior ring involvement, which is detected superiorly by CT compared to X-ray, has an impact on outcome and may require modified treatment. We want to demonstrate if posterior ring involvement has an influence on different types of outcome in primarily conservatively treated acute FFP, questioning the usefulness of early CT. Additionally we analysed the early fracture pattern in cases where conservative treatment failed with need for secondary surgery. METHODS A retrospective cohort study of 155 consecutive patients, recruited between 2009 and 2016, aged over 65 years diagnosed with an acute LE-PFr on X-ray at the emergency department of a single, level-one trauma centre and receiving an early CT. A set of outcome parameters was compared between patients with an isolated pubic rami fracture (CTia) and patients who had a combined posterior pelvic ring fracture (CTcp). RESULTS There were 155 patients of whom 85.2% were female with a mean age of 83 years. 76.8% of patients living at home returned home and 15.5% moved to a nursing home. Mortality rate during hospitalisation was 6.4% and 14.8% at one year post-trauma. Secondary fracture displacement occurred in 22.6%. Secondary surgery was performed in 6 cases (3.9%). Median hospitalisation length of stay was 21 days (range 0 to 112 days). There was no significant association between the subgroups and change in residential status (p = 0.65), complications during hospitalisation (p = 0.75), mortality rate during admission (p = 0.75) and at 1 year (p = 0.88), readmission within 30 days (p = 0.46) and need for secondary surgery (p = 0.2). There was a significant increased median length of stay (p = 0.011) and rate of secondary displacement (p = 0.015) in subgroup CTcp. Secondary displacement had no impact on in-hospital complications (p = 0.7) nor mortality rate during admission (p = 0.79) or at 1 year (0.77). Early CT in patients who underwent secondary surgery showed stable B2.1 lesions in 4 of 6 cases. CONCLUSIONS Our data suggest that early CT in patients with conservatively treated acute LE-PFr in order to detect posterior lesions, has limited value in predicting failure of conservative treatment.

Abstract
BACKGROUND Lateral compression type1 (LC-1) fragility fractures are a common, painful injury in older adults resulting in reduced mobility. The incidence of these fractures is increasing with the growing older adult population. The current standard of care is non-surgical management; however, patients with this injury are at risk of long-term immobility and related complications. INFIX is a pelvic fixation device used in younger patients with high-energy fractures. The device is fitted via a percutaneous technique with no external pin sites and has good purchase even in osteoporotic bone. It therefore has the potential to be well tolerated in patients with LC-1 fragility fractures. INFIX could improve patients' ability to mobilise and reduce the risk of immobility-related complications. However, there is a risk of complications related to surgery, and robust evidence is required on patient outcomes. This study will investigate the clinical and cost-effectiveness of surgical fixation with INFIX compared to non-surgical management of LC-1 fragility fractures in older adults. METHODS A multi-centre randomised controlled trial of 600 patients allocated 1:1 to non-surgical management or INFIX surgery. The study will have a 12-month internal pilot to assess recruitment and trial feasibility. The primary outcome will be the patient quality of life over 6 months, measured by the patient-reported EQ-5D-5L. The secondary outcomes will include physical function, mental health, pain, delirium, imaging assessment, resource use, and complications. DISCUSSION The L1FE study aims to compare the clinical and cost-effectiveness of surgical and non-surgical management of people aged 60 years and older with LC-1 fragility fractures. The trial is sufficiently powered and rigorously designed to inform future clinical and patient decision-making and allocation of NHS resources.

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.

Abstract
Background Pelvic fractures in older patients are associated with relevant morbidity and mortality. Both might be determined by fracture morphology and/or patient characteristics. The aim of this project is to investigate the prognostic value of specific fracture characteristics with respect to overall survival and to compare it with an established classification system. Methods Retrospective analysis of patients ≥ 60 years, treated conservatively for a CT-scan verified, low-energy pelvic ring fracture between August 2006 and December 2018. Survival data was available from patients’ charts and cantonal or national registries. The prognostic value of fracture characteristic describing the anterior and posterior involvement of the pelvic ring was investigated. This analysis was repeated after patients were stratified into a high-risk vs a low-risk group according to patient characteristic (age, gender, comorbidities, mobility, living situation). This allowed to assess the impact of the different fracture morphologies on mortality in fit vs. frail senior patients separately. Results Overall, 428 patients (83.4% female) with a mean age of 83.7 years were included. Two thirds of patients were still living in their home and mobile without walking aid at baseline. In-hospital mortality was 0.7%, overall, one-year mortality 16.9%. An independent and significant association of age, gender and comorbidities to overall survival was found. Further, the occurrence of a horizontal sacral fracture as well as a ventral comminution or dislocation was associated with an increased mortality. The effect of a horizontal sacral fracture was more accentuated in low-risk patients while the ventral fracture components showed a larger effect on survival in high-risk patients. Conclusion Specific fracture characteristics may indicate a higher risk of mortality in conservatively treated patients with a low-energy pelvic ring fracture. Hence, they should be taken into account in future treatment algorithms and decisions on patient management.

Focusing on individual morphological fracture characteristics of pelvic ring fractures in elderly patients can support clinical decision making. BMC Geriatr 2022; 22:543.

Abstract
Introduction Pelvic ring fractures in the elderly are often caused by minor trauma. Treatment of these patients is currently based on fracture classification, clinical course, and ability to mobilize. Our aim was to identify morphological fracture characteristics with potential prognostic relevance and evaluate their association with clinical decision making and outcome, as well as their interobserver reliability. Methods Five fracture characteristics were investigated as potential variables: 1. Extent of the dorsal pelvic ring fracture (absent, unilateral, bilateral); 2. Extent of the ventral pelvic ring fracture (absent, unilateral, bilateral); 3. Presence of a horizontal sacral fracture; 4. Ventral dislocation; 5. Ventral comminution. These characteristics were assessed retrospectively in a series of 548 patients. The association of their presence with the decision to perform surgery, failure of conservative treatment and the length of hospital stay (LOS) was determined. Further, the inter-observer reliability for the specific characteristics was calculated and the relation with survival assessed. Results Four of the five evaluated characteristics showed an association with clinical decision making and patient management. In particular the extent of the dorsal fractures (absent vs. unilateral vs. bilateral) (OR = 7.0; p < 00.1) and the presence of ventral comminution/dislocation (OR = 2.4; p = 0.004) were independent factors for the decision to perform surgery. Both the extent of the dorsal fracture (OR = 1.8; p < 0.001) and the presence of ventral dislocation (OR = 1.7; p = 0.003) were independently associated with a prolonged overall LOS. The inter-observer agreement for the fracture characteristics ranged from moderate to substantial. A relevant association with increased mortality was shown for horizontal sacral and comminuted ventral fractures with hazard ratios (HR) of 1.7 (95% CI: 1.1, 2.5; p = 0.008) and HR = 1.5 (95% CI: 1.0, 2.2; p = 0.048). Conclusion In the elderly, the extent of the dorsal fractures and the presence of ventral comminution/dislocation were associated to the decision to undergo surgery, failure of conservative treatment and length of stay. Survival was related to horizontal sacral fractures and ventrally comminuted fractures. These characteristics thus represent a simplified but highly informative approach for the evaluation of pelvic ring fractures in the elderly. This approach can support clinical decision making, promote patient-centred treatment algorithms and thus improve the outcome of individualized care.

Abstract
INTRODUCTION Non-operative management of pelvic ring injuries in the elderly is associated with a high risk of one-year mortality. The majority of these injuries are the result of a low-energy mechanism, however, due to the multiple medical comorbidities in this patient population the injuries are associated with a high degree of morbidity. The purpose of this study was to determine the one-year mortality risk after operative treatment of pelvic ring injuries in a geriatric patient population and the effect of patient and injury characteristics on the risk of mortality. PATIENTS AND METHODS We performed a retrospective review of patients over the age of 70 who underwent operative fixation of a pelvic ring injury at two Level 1 trauma centers between January 2016 and June 2019. Medical records were reviewed for patient and injury characteristics including: Charlson Comorbidity Index (CCI), American Society of Anesthesiologists (ASA) physical status score or Injury Severity Score (ISS), hospital and intensive care unit (ICU) length of stay (LOS). The primary outcome of interest was the one-year mortality risk following operative treatment. Secondary outcomes included the effect of patient and injury characteristics on the one-year mortality risk and the hospital LOS. RESULTS Ninety patients were included with an average age of 79.8 ± 6.5 years. The overall mortality was 8.9% (n = 8) and was significantly associated with the CCI. There was no significant effect related to the ASA physical status score or ISS. The average hospital LOS was 9.2 ± 7.3 days and was associated with the CCI, ASA physical status score, and ISS. DISCUSSION Non-operative management of pelvic ring injuries in geriatric patients is associated with a high risk of one-year mortality. Our findings suggest operative treatment of these fractures is associated with an acceptable risk of one-year mortality that falls below the commonly reported range for non-operatively managed injuries. Furthermore, the risk of mortality was significantly associated with the patient's pre-injury state as determined by the CCI.

Abstract
Fragility fractures of the pelvis (FFP) are a clinical entity with a rapidly growing incidence among elderly women. The characteristics of these fractures are different from those appearing after high-energy trauma. In 2013, the comprehensive FFP-classification provided a new framework for analysis of these fractures. It is based on the estimation of loss of stability in the pelvic ring. It is connected with recommendations for surgical treatment, justified by the fact that higher instabilities will need surgical stabilization. Since ist appearance, we can observe an increasing clinical-scientific interest in FFP. Multiple publications use the FFP-classification studying the characteristics of fractures, choice of treatment and outcome. Other studies focus on minimal-invasive techniques for stabilization. The actual knowledge describes higher mortality rates as the reference population, lower mortality rates after operative treatment but for the price of surgery-related complications. Mobility, independency and quality of life are worse than before the fracture, independent of the FFP-classification and the type of treatment. The classification triggered a rapid increase of expertise. This publication gives a detailed overview on the evolution from eminence to evidence.

Does surgical treatment for unstable fragility fracture of the pelvis promote early mobilization and improve survival rate and postoperative clinical function? Eur J Trauma Emerg Surg 2021; 48:3747-3756. [PMID: 34156485 DOI: 10.1007/s00068-021-01729-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Accepted: 06/11/2021] [Indexed: 01/31/2023]
Abstract
PURPOSE This retrospective multicenter study aimed to compare rates of early mobilization and survival and functional outcome of surgical treatment (S) with that of conservative treatment (C) according to each unstable fragility fracture of the pelvis (FFP) classification type with displacement of the posterior component ≥ 5 mm. METHODS We analyzed 64 patients with unstable type III and IV FFP who could move and transfer themselves before injury and had ≥ 5 mm displacement of the posterior component. We compared survival rate, early mobilization, walking ability at final follow-up, and complications at admission for each type of surgical and conservative treatment. RESULTS Most of the unstable FFP were type IIIa and IVb in the study population. Type III comprised 40 cases (group S:13/group C:27) and type IV comprised 24 cases (group S:7/group C:17). There were no significant differences in 3 month and 1 year survival rates, although group C (III) had the tendency of higher mortality rate (p = 0.08). Mobilization (transferring to a wheelchair) was enabled significantly earlier in group S (III) than in group C (III) (p = 0.02), but in type IV, most patients enabled early mobilization even without surgical intervention. There were no significant differences in hospital complications and walking ability at final follow-up. CONCLUSION In this study, the superiority of surgical treatment for unstable FFP was not proven. However, the results suggest that type IVb may be a relatively stable type compared to type III and that type IVb should be considered separately from bilaterally complete unstable sacral fractures due to high-energy trauma.

Abstract
INTRODUCTION Classification and management of osteoporotic pelvic ring injuries (OPRI) continue to pose a considerable challenge to orthopaedic traumatologists. The currently used fragility fractures of the pelvis (FFP) classification of OPRI has recently been shown to have significant weaknesses. The aim of this study therefore was to propose a new, simple, yet comprehensive alphanumeric classification (ANC) of OPRI and to assess its intra- and interobserver reliability. Furthermore, its potential advantages over the FFP classification are discussed. MATERIALS AND METHODS One hundred consecutive CT scans from patients with OPRI were evaluated by three orthopaedic traumatologists with varying levels of experience and one musculoskeletal radiologist. Intra- and interobserver reliability of the proposed classification system was assessed using weighted kappa (κ) statistics and percentage agreement. In addition, the Fleiss' kappa statistic was computed to assess interobserver agreement among all four raters. RESULTS Overall intraobserver reliability of the proposed ANC was substantial [κ ranging from 0.71 to 0.80; percentage agreement: 70% (range, 67-76%)]. Overall interobserver reliability between pairs of raters was substantial as well [κ ranging from 0.61 to 0.68; percentage agreement: 58% (range, 53-61%)]. For ANC types, groups and subgroups, intra- and interobserver reliability were substantial to almost perfect. Interobserver agreement among all four raters was moderate to substantial, with Fleiss' kappa values of 0.48, 0.69, 0.71 and 0.52 for ANC overall, types, groups and subgroups, respectively. CONCLUSION The proposed ANC of OPRI demonstrated overall reliability comparable to that of the FFP classification. The ANC, however, is simple, more comprehensive, and consistently relates to injury severity.

Abstract
BACKGROUND Posterior pelvic ring injury (PPRI) can be challenging to diagnose and visualize using plain radiographs; sometimes, PPRI is even overlooked. This study aimed to investigate differences between isolated pubic ramus fractures and fractures concomitant with PPRI in elderly patients. HYPOTHESIS Elderly patients with pubic ramus fractures and concomitant PPRI present different characteristics than patients with isolated ramus fractures. PATIENTS AND METHODS We retrospectively reviewed data of 65 patients aged≥65 who visited the emergency department with a pubic ramus fracture on plain radiograph between January 2013 and December 2018. Patients were divided into two groups based on whether PPRI was found by computed tomography (CT). We then compared patient data and fracture characteristics between the two groups, including displacement and location of the pubic ramus fracture and presence of complete anterior pelvic ring disruption (i.e., concurrent superior and inferior rami fracture). RESULTS PPRI was identified in 49 of 65 patients (75%) on CT. There was greater displacement of the pubic ramus fracture in patients with concomitant PPRI than in those with isolated pubic ramus fractures (4.6mm and 2.2mm, respectively, p<0.001). PPRI more commonly accompanied ramus fractures located medially to the obturator foramen than ramus fractures located in the obturator foramen or laterally to the obturator foramen (96%, 52%, and 77%, respectively, p=0.001). Complete anterior pelvic ring disruption was associated with significantly more concomitant PPRI relative to incomplete anterior pelvic ring disruption (84% and 22%, respectively, p<0.001). DISCUSSION When a pubic ramus fracture is markedly displaced, located medially to the obturator foramen and complete anterior pelvic ring disruption, care should be taken to assess PPRI. LEVEL OF EVIDENCE IV, retrospective study.

J Clin Med 2020; 9:jcm9082498. [PMID: 32756494 PMCID: PMC7463797 DOI: 10.3390/jcm9082498] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 07/28/2020] [Accepted: 07/29/2020] [Indexed: 11/23/2022] Open
Abstract
Background: Fractures of the pubic ramus without involvement of the posterior pelvic ring represent a minority of fragility fractures of the pelvis (FFP). The natural history of patients suffering this FFP Type I has not been described so far. Material and methods: All patients, who were admitted with isolated pubic ramus fractures between 2007 and mid-2018, have been reviewed. Epidemiologic data, comorbidities, in-hospital complications, and one-year mortality were recorded. Of all surviving patients, living condition before the fracture and at follow-up was noted. Mobility was scored with the Parker Mobility Score, quality of life with the European Quality of Life 5 Dimensions 3 Level (EQ-5D-3L), subjective sensation of pain with the Numeric Rating Scale (NRS). Results: A consecutive series of 138 patients was included in the study. There were 117 women (84.8%) and 21 men (15.2%). Mean age was 80.6 years (SD 8.6 years). 89.1% of patients presented with comorbidities, 81.2% of them had cardiovascular diseases. Five patients (4%) died during hospital-stay. Median in-hospital stay was eight days (2–45 days). There were in-hospital complications in 16.5%, urinary tract infections, and pneumonia being the most frequent. One-year mortality was 16.7%. Reference values for the normal population of the same age are 5.9% for men and 4.0% for women. One-year mortality rate was 22.2% in the patient group of 80 years or above and 8.8% in the patient group below the age of 80. The rate of surviving patients living at home with or without assistance dropped from 80.5% to 65.3%. The median EQ-5D-Index Value was 0.62 (0.04–1; IQR 0.5–0.78). Reference value for the normal population is 0.78. Average PMS was 4 and NRS 3. Within a two-year period, additional fragility fractures occurred in 21.2% and antiresorptive medication was taken by only 45.2% of patients. Conclusion. Pubic ramus fractures without involvement of the posterior pelvis (FFP Type I) are serious adverse events for elderly persons. During follow-up, there is an excess mortality, a loss of independence, a restricted mobility, and a decreased quality of life. Pubic ramus fractures are indicators for the need to optimize the patient’s general condition.

Abstract
Background Research on mortality and comorbidity associated with pelvic fractures in older patients is scarce. We aimed to determine the short- and long-term mortality rates of older patients with a pelvic ring fracture compared with both an age-matched cohort of patients with a femoral neck fracture and a general population, and to investigate 30- and 60-day readmission rates after pelvic fracture. Methods This was a retrospective cohort study done in an emergency department of a level II/III trauma center. All patients aged over 70 years diagnosed with a pelvic or acetabular fracture between January 2010 and December 2016 in our ED were identified. Two reference populations were used: patients operated due to femoral neck fracture in our institution between 2007 and 2008 and a general population aged 70 years or more. Results Two hundred nineteen patients were identified. 30- and 90-day mortality was 7.3 and 11.4%, respectively. Compared to the general population, a pelvic fracture was associated with an 8.5-fold (95% CI: 5.2–13.9) and 11.0-fold (95% CI: 5.4–22.3) 90-day mortality risk in females and males, respectively. We could not observe a difference in the risk of 90-day mortality between femoral neck fracture patients and patients with a pelvic fracture. Within 30 days, 28 (12.8%) pelvic fracture patients were readmitted for in-patient care in our hospital. Conclusions The mortality of older patients with pelvic ring fractures resembles that after hip fracture. Although older patients with a pelvic ring fracture rarely require operative treatment, the severity of the injury should not be considered as a class apart from hip fracture.

[PMID: 31463604 DOI: 10.1007/s00068-019-01213-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Accepted: 08/16/2019] [Indexed: 10/26/2022]
Abstract
PURPOSE Biomechanical studies of the pelvis are usually performed using dissected pelvic specimens or synthetic bones. Thereby the stabilising effect of the surrounding soft tissues is analysed insufficiently. Biomechanical data for isolated anterior pelvic ring fractures are currently missing. Therefore, the purpose of this study was to develop a novel testing device for biomechanical analyses of the pelvis and to investigate two different anterior pelvic ring fractures in a cadaveric model with intact peripelvic soft tissues. METHODS A new biomechanical table construction which enables the fixation and testing of complete cadaveric specimens was developed. It was used to investigate the relative motion and stiffness changes due to unilateral osteotomy of the superior and inferior pubic ramus. Five cadavers with a mean age of 55.6 years (± 15.53 years) were included and loaded with a sinusoidal, cyclic (1 Hz), compressive force of up to 365 N over ten cycles for each condition. RESULTS Biomechanical testing of the pelvis with complete appended soft tissues was feasible. Native stiffness without a pelvic fracture was 64.31 N/mm (± 8.33 N/mm). A standardised unilateral osteotomy of the superior pubic ramus reduced the stiffness under isolated axial load by 2% (63.05 N/mm ± 7.45 N/mm, p = 0.690). Additional osteotomy of the inferior pubic ramus caused a further, statistically not significant, decrease by 5% (59.57 N/mm ± 6.84 N/mm, p = 0.310). CONCLUSIONS The developed test device was successfully used for biomechanical analyses of the pelvis with intact peripelvic soft tissues. In a first study, isolated unilateral fractures of the anterior pelvic ring showed no relevant biomechanical variation compared to the intact situation under isolated axial load. Only 7% of the measured stiffness was created by both unilateral pubic rami. Therefore, the clinical practice to treat unilateral anterior pelvic ring fractures conservatively is supported by the results of this study.

Abstract
INTRODUCTION Pelvic fragility fractures (PFF) are common in older people and associated with a significant burden of mortality and morbidity. This is related to the challenges of appropriate pain control and early mobilisation. The current standard for treatment of PFF is non-surgical management. Minimally invasive surgical techniques for sacral fracture stabilisation have been shown to improve outcomes in terms of pain control and mobility, and they are safe. Randomised controlled trials are required before recommendations can be made for surgical management of PFF to become the new standard of care. This feasibility study will explore several uncertainties around conducting such a trial. METHODS AND ANALYSIS ASSERT (Acute Sacral inSufficiEncy fractuRe augmenTation) is a single-site randomised controlled, parallel-arm, feasibility trial of surgical stabilisation versus non-surgical management of acute sacral fragility fractures in people aged 70 years and over. Patients will be randomised to either surgical or non-surgical group on a 1:1 ratio. Follow-up of participants will occur at 2, 4 and 12 weeks with safety data collected at 52 weeks. Primary objectives are to determine feasibility and design of a future trial, including outcomes on recruitment, adherence to randomisation and safety. This will be supplemented with a qualitative interview study of participants and clinicians. Secondary objectives will inform study design procedures to determine clinical and economic outcomes between groups, including scored questionnaires, analgesia requirements, resource use and quality of life data. Data analysis will be largely descriptive to inform outcomes and future sample size. ETHICS AND DISSEMINATION Ethical approval was granted by the North East Newcastle and North Tyneside 2 Research Ethics Committee (reference 18/NE/0212). ASSERT was approved and sponsored by Nottingham University Hospitals NHS Trust (reference 18HC001) and the Health Research Authority (reference IRAS 232791). Recruitment is ongoing. Results will be presented at relevant conferences and submitted to appropriate journals on study completion. TRIAL REGISTRATION NUMBER ISRCTN16719542; Pre-results.

Abstract
OBJECTIVES To undertake a systematic review of the evidence base for the effectiveness of surgical fixation of lateral compression (LC-1) fragility fractures of the pelvis compared with non-surgical approaches. SEARCHES MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and two international trials registers were searched up to January 2017 (MEDLINE to February 2019) for studies of internal or external fixation of fragility fractures of the pelvis. PARTICIPANTS Patients with lateral compression pelvic fractures, sustained as the result of a low-energy mechanism, defined as a fall from standing height or less. INTERVENTIONS Surgery using either external or internal fixation devices. Conservative non-surgical treatment was the defined comparator. OUTCOME MEASURES Outcomes of interest were patient mobility and function, pain, quality of life, fracture union, mortality, hospital length of stay and complications (additional operative procedures, number and type of adverse events and serious adverse events). QUALITY ASSESSMENT AND SYNTHESIS The Joanna Briggs Institute Checklist for Case Series was used to assess the included studies. Results were presented in a narrative synthesis. RESULTS Of 3421 records identified, four retrospective case series met the inclusion criteria. Fixation types were not consistent between studies or within studies and most patients had more than one type of pelvic fixation. Where reported, mobility and function improved post-surgery, and a reduction in pain was recorded. Length of hospital stay ranged from 4 days to 54 days for surgical fixation of any type. Reported complications and adverse outcomes included: infections, implant loosening, pneumonia and thrombosis. Use of analgesia was not reported. CONCLUSIONS There is insufficient evidence to support guidance on the most effective treatment for patients who fail to mobilise after sustaining an LC-1 fragility fracture. TRIAL REGISTRATION NUMBER CRD42017055872.

It was not a hip fracture - you were lucky this time - or perhaps not! A prospective study of clinical outcomes in patients with low-energy pelvic fractures and hip contusions. Injury 2019; 50:913-918. [PMID: 30910240 DOI: 10.1016/j.injury.2019.03.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Accepted: 03/16/2019] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Prehospital and hospital emergency care guidelines have been developed for patients with suspected hip fracture. Initial radiography can identify a number of patients with other injuries, generally pelvic fractures and hip contusions. Little is known about the prognosis for these patients. The aim of this study is twofold: i) to investigate the injury pattern of patients assessed in prehospital emergency care as suffering from a suspected hip fracture and ii) to compare clinical outcomes between patients with verified hip fracture (HF) and those with other hip injuries (OHI). METHOD The study design was prospective. Older patients with suspected HF after low-energy trauma were identified in prehospital emergency care. Injury type was determined by radiological imaging. Comparisons of length of stay, adverse events, repeated prehospital emergency care and mortality were made between verified HF and OHI cases. RESULTS 449 patients were included, 400 in the HF and 149 in the OHI group (86 hip contusions, 46 pelvic fractures and 17 other injuries/diseases). The HF group had a significantly longer hospital stay (9.5 days vs. 6.3 for the OHI group; p < 0.001) and more adverse events while in hospital (34% vs. 19%; p < 0.001). We found no evidence that the groups differed with regard to other outcomes: mortality during hospital stay (4% vs. 2%, p = 0.42), at 4 (16% vs. 13%; p = 0.35) and 12 months (21 vs. 23%; p = 0.64), the proportion that experienced an adverse event (24% vs. 22%; p = 0.65) and the proportion that required another ambulance transport within 6 months after discharge (40% vs. 34%; p = 0.16). The results were not strongly affected by adjustments for possible confounders. CONCLUSION Older patients who suffer a low-energy pelvic fracture or a hip contusion are common in prehospital and hospital emergency care. These patients need attention as they have poor outcomes in terms of adverse events, mortality and recurrent need for ambulance transport after discharge from hospital. While individualized multidisciplinary care is recommended for hip fracture patients, it might also be suitable for other geriatric hip injuries.

Abstract
INTRODUCTION The classification and management of osteoporotic pelvic ring injuries (OPRI) remain challenging. The fragility fractures of the pelvis (FFP) classification system proposed by Rommens and Hofmann constitutes the first comprehensive classification system of OPRI and may contribute to a more thorough assessment and grading of these injuries. The reliability of the FFP classification system, however, has not been evaluated yet. The purpose of this study therefore was to determine the inter- and intraobserver reliability of the FFP classification system and to critically analyse its strengths and weaknesses. MATERIALS AND METHODS One-hundred pelvic CT scans obtained from a consecutive series of patients aged 70 years and older who sustained a low-energy pelvic ring injury were included in this study. Three orthopaedic traumatologists of varying levels of experience (one experienced pelvic surgeon, one consultant, one resident) and one musculoskeletal radiologist independently classified each OPRI according to the FFP classification in two different sessions. Intra- and interobserver reliability were determined using percentage agreement and Cohen's Kappa coefficients. RESULTS The observed relative distribution of FFP fracture types was comparable to that reported in the original study by Rommens and Hofmann. Overall interobserver reliability for all 100 cases was moderate with Kappa values from 0.42 to 0.59 (mean percentage agreement: 61% (54%-68%)), while intraobserver reliability was substantial with Kappa values from 0.68 to 0.72 (mean percentage agreement: 77% (76%-78%)). Subgroup analysis revealed lowest reliability for the classification of Type IIc, IIIc and IVb injuries (32 cases). Within this subgroup of combined anterior and posterior OPRI involving a complete nondisplaced or displaced (uni- or bilateral) sacral fracture, Kappa values for interobserver reliability ranged from 0.10 to 0.52, while those for intraobserver reliability ranged from 0.29 to 0.66. CONCLUSION Overall interobserver reliability of the FFP classification system was moderate, while intraobserver reliability was substantial. Despite the acceptable overall reliability, classification of FFP subtypes involving a complete nondisplaced or displaced sacral fracture showed relatively poor reliability. The latter limits the usefulness of the FFP classification for both clinical and research purposes and needs to be addressed in future studies.

Abstract
INTRODUCTION Pubic rami fractures are common fractures in a growing osteoporotic geriatric population. Concomitant posterior ring fractures (cPRF) are often found when properly looked for. The pain and consequent immobilization leaves this vulnerable patient group at risk for complications. Conservative therapy is usually sufficient, but with cPRF's surgery can be indicated. Although previous studies have pointed out that mortality rates are high, longer term morbidity outcomes are lacking. This study aims to further establish the longer term consequences of these fractures. Risk factors will be identified for complications, also addressing the possible differences between patients with or without a cPRF. METHOD Retrospective analysis of patients aged over 65 years sustaining a pubic rami fracture in the North-West Hospital Group Alkmaar combined with a survey to establish risk factors for morbidity and mortality after 6 months' post trauma. Multiple logistic regression analysis was used to identify risk factors. RESULTS 117 patients matched inclusion criteria with a median age of 83 and of which 86% was female. 23 cPRF's were identified. Significant deterioration in ambulation and independency was found. 34% was institutionalized at discharge. 49% lost their independent mobility status and 40% of the patients did not experience a full recovery. One-year mortality rate was 23%. Patients with a cPRF had a significant higher complication rate (44 vs 18% p = 0.02), but mortality and other morbidity outcomes did not statistically differ. The strongest predictor for 1-year mortality was complications during admission and a dependent ambulatory status (OR 5.2 and 4.1 respectively). CONCLUSION Pubic fractures with or without involvement of the posterior pelvic ring in patients aged over 65 have a significant impact on mobility and independency. Mortality rates are similar to hip fracture patients. Careful evaluation of every patient's mobility status is necessary to identify patients at risk for complications and determine their future health care needs. Future studies are needed to achieve consensus on diagnostic and treatment protocols and identify ways to decrease the significant impact of this injury.

Abstract
OBJECTIVES To analyze the changes in demographic data stratified for age, sex and type of injury of elderly patients suffering from pelvic ring fractures over a 22-year observation period. DESIGN/SETTING Data has been collected prospectively, multi-centrically in hospitals participating in the German Pelvic Trauma Registry. PATIENTS We analyzed the data of 5665 patients with an age ≥60years included in the German Pelvic Trauma Registry from 1991 to 2013. KEY RESULTS Over the 22-year study period the frequency of type A fractures decreased significantly from 84.8% to 43.9%, while type C and, in particular, type B fractures significantly increased from 7.0% and 8.2% to 14.3% and 41.8%. In patients between 60 and 70 years of age the frequency of type B and C fractures was higher compared to patients >70years. The proportion of female patients, who represent the majority of the cohort (75%), was stable over the entire observation period. Interestingly, type A fractures were found more frequently in females, while type B and C fractures were found more frequently in males. CONCLUSIONS With the predicted demographic change and a shift toward more severe injury patterns (type B and C pelvic fractures) in the elderly population, trauma departments will need to develop specific surgical concepts for geriatric patients with pelvic ring fractures.

Abstract
INTRODUCTION Analyzing the different age groups in a population who suffered a pelvic ring fracture it becomes obvious that there are important differences between the pelvic ring lesions of an elderly patient compared to a young adult concerning trauma mechanism, fracture pattern and therapeutic options. In the elderly patient it is very important to achieve maximum of stability if surgery is necessary in order to avoid early failure of the ostheosynthesis under mobilization with full weight bearing. PATIENTS AND METHODS 15 patients (14 female) with fragility fractures of the pelvis that required surgical stabilization were eligible to participate in this study from December 2012 to December 2014. Such details were documented and analysed as patient demographics, mechanism of injury, fracture classification, operative treatment and postoperative radiological parameters of achieved bone-implant interface. RESULTS The average age of the patients was 79.9 years (SD 9.0 years). According to Rommens five patients had a fragility fracture of the pelvis Type II-c, one a Type III-c, six a Type IV-b and three a Type IV-c. Four patients were treated by a cement augmented transiliac internal fixation (caTIFI). Seven patients received a cement augmented iliolumbar fixation. In all these patients the Schanz screws applied to the ilium were placed in an oblique dorsoventral direction into the supraacetabular bone canal (mean length of screws 100 ± 20mm, max. 135 mm, min. 70 mm). Even though in four patients the iliosacral joint was hit tangential and one cortex perforation without any cement leakage appeared no revision surgery was necessary. Overall the clinical findings including mobilisation with full weight bearing showed a sufficient mechanically stability in all patients. CONCLUSION The focus of this study was to describe the modified surgical technique of the caTIFI with placing the Schanz screws from the posterior superior iliac spine to the anterior inferior iliac spine into the supraacetabular bone canal. Usage of cannulated and perforated Schanz screws gives the opportunity to control the correct position of the screws before implanting them. Another advantage is that additional stability can be obtained by cement augmentation. We believe that the new technique of the caTIFI provides a greater intraoperative versatility and a greater mechanical stability for fragility fractures of the pelvis.

Abstract
BACKGROUND With increasing life expectancy, fragility fractures of the pelvic ring (FFP) are becoming frequent. In elderly, osteoporosis leads to a decrease of bone strength and resistance to the ligament's traction; this represents the most important difference between FFP and fractures in young patients. Usually, these fractures are underestimated and treatment is often conservative. AIMS To evaluate clinical and surgical outcomes of surgically treated patients with FFP. METHODS We retrospectively enrolled 14 patients, in our Trauma Center, underwent surgery procedures for FFP between 2012 and 2014. All patients attended clinical and radiological investigation at 1, 3, and 6 months postoperatively and every year after surgery with a mean follow-up of 22 months. RESULTS At 6-month follow-up, 11 patients resulted asymptomatic: able to maintain standing position and walk without crunches. Two patients were able to walk with one crunch. The patient with history of previous acetabular fracture walks with two crunches and is still waiting for total hip arthroplasty. DISCUSSION The compromised health status and the diminished bone-healing capacity, in elderly, decrease chances for a good clinical outcome. In literature, many authors suggest that mortality rate in patients with FFP is similar to those with hip fracture. Diagnosis of FFP is very important: these fractures are highly disabling in elderly and can lead to displacement and instability. For these reasons, correct diagnosis and well-conduct preoperative plan are necessary to improve stability of fractures and support bone healing. After diagnosis, an anti-osteoporotic treatment is indicated to improve bone quality and bone healing. CONCLUSIONS Our study shows encouraging results and demonstrates that minimally or less invasive osteosynthesis technique could lead to good outcome in these patients.

Abstract
Trauma is one of the leading causes of death before the age of 40 years and approximately 5% of patients with trauma who require hospital admission have pelvic fractures. This article updates the emergency department classification of pelvic fractures first described in 2000. This information is of practical value to emergency physicians in identifying the potential vascular, genitourinary, gastrointestinal, orthopedic, and neurologic complications and further assists them in the initial evaluation and treatment of patients with pelvic fractures.

Abstract
OBJECTIVE To study the implications of osteoporotic pelvic fractures in older patients in terms of mortality, length of hospital stay and independent living. METHODS The study included 110 consecutive patients, aged over 60 years, with osteoporotic pelvic fractures admitted to the Queen Elizabeth Hospital, Gateshead, between July 2009 and March 2011. Demographic and routine clinical data were collected prospectively until date of discharge, and vital status data were collected up to 3 months post-fracture. These data were analysed to assess associations with outcomes such as length of hospital stay, mortality and loss of independence (according to changes in residential housing status). RESULTS Fourteen patients died either in hospital, or within 3 months of fracture. Length of hospital stay was associated with age (b=0.77 days per year, 95% CI 0.001, 1.54, P=0.05) and was significantly longer in those with acute medical problems on admission (b=21.2 days, 95% CI 8.72, 33.73, P=0.001). The odds of changing from independent to institutionalised accommodation were significantly associated with age (OR 1.08 per year, 95% CI 1.01, 1.04, P=0.007) and length of hospital stay (OR 1.12 per day, 95% CI 1.01, 1.04, P=0.007). CONCLUSION In-hospital mortality rates in this patient group are similar to those seen for hip fractures, yet pelvic fractures in older people receive relatively little in the way of attention or funding. Guidelines to improve the management of such fractures in older people are important to improve care while in hospital, reduce time spent in hospital and reduce the impact on independent living.

Abstract
Due to the increasing life expectancy, orthopaedic surgeons are more and more often confronted with fragility fractures of the pelvis (FFPs). These kinds of fractures are the result of a low-energy impact or they may even occur spontaneously in patients with severe osteoporosis. Due to some distinct differences, the established classifications for pelvic ring lesions in younger adults do not fully reflect the clinical and morphological criteria of FFPs. Most FFPs are minimally displaced and do not require surgical therapy. However, in some patients, an insidious progress of bone damage leads to increasing displacement, nonunion and persisting instability. Therefore, new concepts for surgical treatment have to be developed to address the functional needs of the elderly patients. Based on an analysis of 245 consecutive patients with FFPs, we propose a novel classification system for this condition. This classification is based on morphological criteria and it corresponds with the degree of instability. Also in the elderly, these criteria are the most important for the decision on the type of treatment as well as type and extent of surgery. The estimation of the degree of instability is based on radiological and clinical findings. The classification gives also hints for treatment strategies, which may vary between minimally invasive techniques and complex surgical reconstructions.

Abstract
UNLABELLED The objective of this study was to describe the incidence and consequences of pelvic fractures in a community cohort. The incidence of pelvic fractures increases with age with a protective effect of higher body mass index. Almost 60% of those with a pelvic fracture required an inpatient stay, with a median of 9 days. There was a higher 3-year mortality in those admitted (17%) vs. those not admitted (6.3%). Given the substantial health burden, further work is required to identify the optimal post-fracture therapeutic strategy to improve outcomes. INTRODUCTION The burden of pelvis fractures is projected to increase, but there is a paucity of community-based studies describing rates, mortality and future fracture risk. We therefore estimated the age, gender and BMI-specific incidence of pelvis fracture in Catalonia (North-East Spain), and assessed hospital stay and mortality following fracture. METHODS The SIDIAP(Q) database contains validated clinical information from computerised medical records of a representative sample of 30% of the population of Catalonia. We conducted a retrospective cohort study including all subjects aged ≥ 40 in SIDIAP(Q) and linked to the regional Hospital Admissions Database from 2007 to 2009. Pelvis fractures were ascertained using ICD-10 codes. Incidence and mortality rates were calculated. RESULTS A total of 1,118,173 patients (582,820 women) were observed for 3 years and 1,356 had a pelvic fracture. The rate for pelvic fracture was 4.35/10,000 person-years (pyar) [95% CI 4.13-4.59] (men-2.73 [2.48-3.01]; women-5.82 [5.46-6.20]). This increased with age, peaking in those over 90 years: 29.41 [25.74-33.59]. Higher BMI was protective (HR 0.75 per SD BMI; [0.69-0.82]). Moreover, 59.1% of fractured patients were hospitalised with a median (IQR) stay of 9 (5-16) days, and after the 3-year follow-up 13.9% died (mortality rate 10.7/100 pyar [9.3-12.3]) with higher rates in those hospitalised (17.0%). CONCLUSIONS Pelvic fractures are associated with high rates of hospitalisation and mortality. Given this, further work is required to identify the optimal post-fracture therapeutic strategy to improve outcomes in this elderly patient group.

Abstract
A 78-year-old woman presented 28 days after a low-impact fall, where she sustained a right pubic ramus fracture, with increasing left hip pain and fever. Her blood results showed a high white cell count and deranged urea and electrolytes. An MRI revealed multiple osteoporotic fractures and bilateral gluteal abscesses with left iliopsoas abscess, which had likely formed in a haematoma of a sacral fracture. She received a long course of intravenous antibiotics and CT-guided drainage of the abscesses. She developed symptoms of cauda equina, but no evidence of epidural extension of the abscess was found at operation. She required neurorehabilitation. This case highlights the complications of pelvic osteoporotic fractures, and high associated morbidity and mortality in the elderly population.

Abstract
BACKGROUND Fractures of the pubic rami are associated with prolonged pain, bed rest and increased morbidity and mortality. Often no further diagnostic work-up is undertaken and the pubic rami fractures are classified as stable injuries. However, fractured pubic rami seem to be only part of the picture and are often associated with posterior pelvic ring injury. This retrospective study was designed to evaluate the posterior ring for undetected injury in patients diagnosed with pubic rami fractures. METHODS All patients (n=233) with diagnosed fractures of the pubic rami were retrospectively retrieved. All patients with a CT scan available at time of admission (n=177) were included in the study. RESULTS In 28.8% of the cases a fracture of the acetabulum was found additionally to the pubic rami. In cases without obvious other injury of the ap radiograph, an injury of the posterior pelvic ring was found on CT scans in 96.8% of the patients. Most lesions represented transforaminal sacral fractures, avulsion fractures of ligaments or compression fractures of the lateral mass. All patients with dorsal injuries could initially be treated conservatively, nevertheless 30% of them needed operative treatment in the course. CONCLUSION Nearly all cases with fractures of the pubic rami do have a lesion elsewhere within the pelvic ring. In patients with prolonged pain and immobility following 'pubic rami fractures' one should be aware that they probably represent an undiagnosed pelvic ring injury and further diagnostic work-up - sometimes even surgery - is warranted.

Abstract
Background Pelvic osteoporotic fractures (POFs) are often associated with considerable morbidity and mortality mainly as a result of infections and cardiovascular events. Patients usually need prolonged institutionalization, rehabilitation, and follow-up, with a high rate of dependency and cost. The most common sites of POFs include the pubic rami, sacrum, ilium, and acetabulum. Combined pubic rami (PROFs) and sacral osteoporotic fractures (SOFs) have been reported, mostly in retrospective studies, describing the mechanism of injury and incidence. The aim of this study was to evaluate the association between PROFs and SOFs and to assess the effect of combined PROFs and SOFs on patients’ mobility, discharge destination, and length of stay. Materials and methods We prospectively studied 67 patients with low-impact PROFs and/or SOFs. There were 54 (80.4%) female and 13 (19.6%) male patients, and the average age was 87.5 (range 65–96) years. All patients were assessed by the fracture liaison service. Patients had magnetic resonance imaging or bone scan when there was history of low back pain following the injury or lumbosacral tenderness on clinical examination. Results The mean length of stay for all patients was 45 (±35) days. Mortality rate was 10.4%. A significant relationship was found between low back pain and a positive finding of sacral fracture. Patients with combined PROFs and SOFs showed significantly longer length of stay than those with isolated PROFs. Conclusions The presence of low back pain and tenderness in patients who had low-impact pelvic injuries was highly suggestive of the presence of an associated SOF. There was a high association between sacral and PROFs. The length of stay of patients with PROFs associated with sacral osteoporotic fractures was significantly longer than that of patients with PROFs only. Therefore, we recommend considering the high association between SOFs and PROFs in planning the management and rehabilitation of patients with POFs.
