Orthop Traumatol Surg Res 2024; 110:103691. [PMID: 37741442 DOI: 10.1016/j.otsr.2023.103691] [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: 12/08/2022] [Revised: 07/04/2023] [Accepted: 08/24/2023] [Indexed: 09/25/2023]
Abstract
BACKGROUND To evaluate the performance in activities of daily living (ADL), level of pain, mortality and rate of complications in patients with a pelvic ring fracture with sacral involvement who were treated conservatively compared to a surgically treated patient collective using percutaneous iliosacral screw fixation. HYPOTHESIS Conservative treatment does not result in inferior clinical outcome compared to operative treatment. PATIENTS AND METHODS A retrospective study of 112 conservatively (n=46) or operatively (n=66) treated patients with an isolated posterior or a combined posterior and anterior pelvic ring fracture was performed. The analysis included: age, sex, mechanism of injury, fracture type according to AO/OTA classification, energy of trauma sustained (no-, low-, high-energy trauma), type of treatment (operative or conservative), complications as well as duration of in-hospital stay. To assess clinical and activity outcome, the visual analog scale for pain (VAS), Barthel Scale, American Society of Anaesthesiologists (ASA) scores as well as mortality were assessed. The mean follow-up was 29.3±14.6 months. Furthermore, a geriatric subgroup (n=68, age≥60, low-energy trauma only) was analyzed. RESULTS The majority of the patients were female (79%) and suffered from low-energy trauma (n=64, 58%). There were no significant differences in the operative and the conservative groups and subgroups concerning VAS, Barthel scores and ASA scores. The survival analyses showed a significantly lower survival rate in the conservative group (41.8±3.6 months) compared to the operative group (55.9±2 months, p=0.002). Similar findings were encountered in the geriatric subgroup analysis. CONCLUSION This study demonstrates equivalent clinical outcome in conservatively and surgically treated patients using a percutaneous iliosacral screw fixation at a mid-term follow-up. However, operatively treated patients showed decreased mortality. This needs to be carefully considered in clinical decision-making but must be further explored using a prospective randomized study approach. LEVEL OF EVIDENCE III.

BMC Musculoskelet Disord 2022; 23:1106. [PMID: 36536363 PMCID: PMC9762048 DOI: 10.1186/s12891-022-06039-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Accepted: 11/29/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Fragility fractures of the sacrum (FFS) have been detected more and more frequently in recent times, and the incidence will continue to increase due to increasing life expectancy. The aim of this study was to compare the clinical outcome of conservative, interventional and surgical treatment of FFS. METHODS Retrospectively, 292 patients (276 women, 16 men) with confirmed FFS were followed up over a period of 2 years. The age of the women was Ø 81.2 (58 - 99) and that of the men Ø 78.1 (76 - 85) years. The pain was quantified using a VAS. Fractures were classified in accordance with the Rommens and Hofmann and with the Denis classification using conventional X-rays, CT and MRI. A QCT of the lumbar spine was performed to quantify bone mineral density. Concomitant diseases of every patient were recorded. An interdisciplinary case conference determined the individual treatment concept considering the age, type of fracture, pain level and comorbidities with classification into conservative, interventional (any type of sacroplasty) or surgical treatment. Over the course pain and independence were measured, complications and patient satisfaction were documented. A vitamin D determination was done, and existing comorbidities were included. RESULTS Patients with a pain level of ≤5 benefited from the conservative therapy measures, with pain levels > 5 significantly delaying the development of mobility. After sacroplasty, the pain reduced significantly, which caused a rapid improvement in mobility without any significant difference being found between vertebro- (VSP), balloon (BSP), radiofrequency (RFS) and cement sacroplasty (CSP). In terms of pain reduction and mobilization, the surgical treated patients benefited from osteosynthesis, although more complex fracture types with lumbopelvic stabilization took longer. Overall, there were no deaths during the hospital stay. Mortality after 12 months was 21.7% for the conservative, 8.4% for the interventional and 13.6% for the surgical therapy group; the differences are significant. For patients in the conservative therapy group who were difficult to mobilize due to pain, the mortality increased to 24.3%. Over 24 months, patients achieved the best independence after sacroplasty. At 12 and 24 months, subjective satisfaction with the therapies was best after sacroplasty, followed by osteosynthesis and conservative measures. All patients had a pronounced vitamin D deficiency and manifest osteoporosis. Cardiovascular pathologies were the main concomitant diseases. CONCLUSIONS Patients with FFS with a low level of pain benefit from conservative therapy measures, whereby complications and mortality increase significantly in the case of persistent immobilizing pain. Patients with an unacceptable level of pain resulting from non-dislocated fractures benefit significantly from sacroplasty. Patients with unstable and displaced fractures (Rommens and Hofmann type III and IV) should be operated on promptly. Different techniques are available for sacroplasty and osteosynthesis, which lead to an improvement of independence and a reduction in mortality.

Abstract
Abstract
Purpose
To compare construct stability of cement augmented sacroiliac screws using two different cementation sites in a biomechanical fragility fracture model of the pelvis.
Methods
A fracture model with an incomplete fracture of the sacral ala and complete fracture of the anterior pelvic ring mimicking a FFP IIB fragility fracture of the pelvis was established in five fresh frozen human cadaveric pelvises. Sacral fracture stabilization was achieved with bilateral 7.3 mm fully threaded sacroiliac screws. Cement augmentation was performed at the tip of the screw (body of S1; Group A) on one side, and at the midshaft of the screw (sacral ala; Group B) on the contralateral side. Biomechanical testing was conducted separately on both sides comprising cyclic loading of axial forces transferred through the tested hemipelvis from L5 to the ipsilateral acetabulum. Combined angular displacement in flexion and internal rotation (“gap angle”), angular displacement of the ilium in relation to the screw (“screw tilt ilium”), and screw tip cutout were evaluated.
Results
Relative interfragmentary movements were associated with significantly higher values in group A versus group B for “gap angle” (2.4° vs. 1.4°; p < 0.001), and for “screw tilt ilium” (3.3° vs. 1.4°; p < 0.001), respectively. No significant difference was indicated for screw tip cutout between the two groups (0.6 mm [Group A] vs. 0.8 mm [Group B]; p = 0.376).
Conclusion
The present study demonstrated less fragment and screw displacements in a FFP IIB fracture model under physiologic cyclic loading by cement augmentation of sacroiliac screws at the level of the lateral mass compared to the center of vertebral body of S1.

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.

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.

Low-energy lateral compression type 1 (LC1) pelvic ring fractures in the middle-aged and elderly affect hospital quality measures and functional outcomes. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:1379-1384. [PMID: 34545463 DOI: 10.1007/s00590-021-03125-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Accepted: 09/13/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE The purpose of this study was to examine hospital quality measures and the long-term functional outcomes associated with lateral compression type 1 [LC1] pelvic ring injuries. METHODS A query was performed from December 2011 to September 2020 at two institutions within one hospital system for patients with a pelvic fracture diagnosis. Chart review was performed on admitted patients to determine demographic information, medical co-morbidities (to calculate Charlson Co-morbidity Index), in-hospital complications, length of stay [LOS], discharge disposition, and 30-day readmission rates. All patients included were treated nonoperatively. An attempt was made to contact all patients for long-term follow-up to assess current functional status with a Short Musculoskeletal Function Assessment [SMFA]. RESULTS Two-hundred and eighty-six patients were included, with 172 (65.9%) patients admitted and analyzed with respect to hospital quality measures. Patients admitted were older (83 vs 80 years, p = 0.015) with more medical co-morbidities (p = 0.001) than those discharged from the emergency department. The average LOS was 5.7 ± 3.7 days and 31 (18%) experienced in-hospital complications. The inpatient mortality rate was 1.2%, and the 30-day readmission rate was 8.1%. When comparing admitted patients without concomitant injuries, admitted patients with concomitant injuries, and non-admitted patients, admitted patients with concomitant injuries were found to have more medical co-morbidities (p = 0.001). Forty-three patients were available for long-term follow-up (average 36.6 ± 7.3 months), with an average SMFA score of 29.0 ± 25.7. CONCLUSIONS Patients admitted for LC1 pelvic fractures are likely to be older with more medical co-morbidities, and up to 1/5th will experience inpatient complications. Although inpatient mortality remains low, this injury pattern can lead to significant functional disability that persists for several years after injury.

Abstract
Purpose Pelvic trauma has increased risk of mortality in the elderly. Our study aimed to analyze the impact of the additional burden of pelvic fractures in severely injured elderly. Methods This is a retrospective analysis of a prospectively maintained trauma registry from 2012 to 2018 at an American College of Surgeons (ACS) verified Level I Trauma Center. Trauma patients aged ≥ 65 years with ISS ≥ 16 and AIS severity score ≥ 3 in at least two body regions were divided in two groups: group I, consisted of elderly polytrauma patients without pelvic fractures, and group II elderly who had concomitant pelvic fractures. We used a double-adjustment method using propensity score matching (PSM) with subsequent covariate adjustment to minimize the effect of confounding factors, and give unbiased estimation of the impact of pelvic fractures. Balance assessment was conducted by computing absolute standardized mean differences (ASMDs) and ASMD < 0.10 reflects good balance between groups. Results Of 12,774 patients admitted during this time, 411 (3.2%) elderly with a mean age of 77.75 ± 8.32 years met the inclusion criteria. Of this cohort, only 92 patients (22.4%) had pelvic fractures. Females outnumbered males (55 vs. 45%). Comparing characteristics of group I and group II using ASMDs, pelvic trauma patients were more likely to have higher systolic blood pressure (SBP), head injuries, lower extremity injuries, anticoagulant therapy, and cirrhosis. Fewer variables differed significantly after matching. We observed few instances of worse outcomes associated with pelvic trauma using PSM with and without covariate adjustment. Crude PSM without covariate adjustment, showed a significantly higher rate of deep vein thrombosis (DVT) for pelvic trauma (p < 0.001). Crude PSM also showed a significantly higher rate of ventilator-associated pneumonia (VAP) in group II (p = 0.006). PSM with covariate adjustment did not confirm differences on these outcomes. PSM both without and with covariate adjustment found lower ventilator days and ICU length of stay among patients with pelvic trauma. No significant differences were seen on 12 outcomes: death, acute kidney injury (AKI), acute respiratory distress syndrome (ARDS), cardiac arrest with cardiopulmonary resuscitation (CPR), myocardial infarction (MI), pulmonary embolism (PE), unplanned intubation, unplanned admission to intensive care unit (ICU), catheter-associated urinary tract infection (CAUTI), and hospital length of stay. Conclusions At a Level I Trauma Center the additional burden of pelvic fractures in seriously injured elderly did not translate into higher mortality. PSM without covariate adjustment suggests worse rates among pelvic trauma patients for DVT and VAP but covariate adjustment removed statistical significance for both outcomes. Pelvic trauma patients had shorter time on ventilator and in the ICU. Whether similar analytic methods applied to patients from larger data sources would produce similar findings remains to be seen.

Abstract
Severe osteoporotic fractures (hip, proximal humerus, pelvic, vertebral and multiple rib fractures) carry an increased risk of mortality. This retrospective cohort study in the French national healthcare database aimed to estimate refracture and mortality rates after severe osteoporotic fractures at different sites, and to identify mortality‐related variables. A total of 356,895 patients hospitalized for severe osteoporotic fracture between 2009 and 2014 inclusive were analyzed. The cohort was followed for 2 to 8 years up to the study end or until the patient died. Data were extracted on subsequent hospitalizations, refracture events, treatments, comorbidities of interest and survival. Time to refracture and survival were described using Kaplan‐Meier analysis by site of fracture and overall. Mortality risk factors were identified using a Cox model. Hip fractures accounted for 60.4% of the sample (N = 215,672). In the 12 months following fracture, 58,220 patients (16.7%) received a specific osteoporosis treatment, of whom 21,228 were previously treatment‐naïve. The 12‐month refracture rate was 6.3% (95% confidence interval [CI], 6.2%–6.3%), ranging from 4.0% (95% CI, 3.7%–4.3%) for multiple rib fractures to 7.8% (95% CI, 7.5%–8.1%) for pelvic fractures. Twelve‐month all‐cause mortality was 12.8% (95% CI, 12.7%–12.9%), ranging from 5.0% (95% CI, 4.7%–5.2%) for vertebral fractures to 16.6% (95% CI, 16.4%–16.7%) for hip fractures. Osteoporosis‐related mortality risk factors included fracture site, previous osteoporotic fracture (hazard ratio 1.21; 95% CI, 1.18–1.23), hip refracture (1.74; 95% CI, 1.71–1.77), and no prior osteoporosis treatment (1.24; 95% CI, 1.22–1.26). Comorbid cancer (3.15; 95% CI, 3.09–3.21) and liver disease (2.54; 95% CI, 2.40–2.68) were also strongly associated with mortality. In conclusion, severe osteoporotic fractures, including certain non‐hip nonvertebral fractures, carry a high burden in terms of mortality and refracture risk. However, most patients received no anti‐osteoporotic treatment. The findings emphasize the importance of better management of patients with severe fractures, and of developing effective strategies to reduce fracture risk in patients with osteoporosis. © 2021 The Authors.

[PMID: 33643677 PMCID: PMC7890705 DOI: 10.1177/2151459320985406] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 11/05/2020] [Accepted: 12/02/2020] [Indexed: 12/19/2022] Open
Abstract
Introduction: A need exists for improved care pathways for patients experiencing low-energy pelvic ring fractures. A review of the current literature was performed to understand the typical patient care and post-acute rehabilitation pathway within the US healthcare system. We also sought to summarize reported clinical outcomes worldwide. Significance: Low-energy pelvic ring fracture patients usually do not qualify for inpatient admission, yet they often require post-acute rehabilitative care. The Center for Medicare and Medicaid Services’ (CMS) 3-day rule is a barrier to obtaining financial coverage of this rehabilitative care. Results: Direct admission of some patients to post-acute care facilities has shown promise with decreased cost, improved patient outcomes, and increased patient satisfaction. Secondary fracture prevention programs may also improve outcomes for this patient population. Conclusions: Post-acute care innovation and secondary fracture prevention should be prioritized in the low-energy pelvic fragility fracture patient population. To demonstrate the effect and feasibility of these improved care pathways, further studies are necessary.

Abstract
Background Pelvic ramus fractures in older patients are associated with substantial morbidity and mortality. There is a paucity of literature on fractures of the pelvis in this age group. The purpose of this study was to report mortality rates following such injuries. In addition, we aimed to describe and quantify the important resultant morbidity in this vulnerable population. Methods We performed a retrospective chart review of all low-energy pelvic ramus fractures in patients more than age 60 years that occurred between January 2000 and December 2005. Data on survival, hospital length of stay, ambulatory status and place of residence were recorded. For comparison, we calculated the mortality rate for a surrogate age- and sex-matched group using Statistics Canada survival data for use as an uninjured control group. Results We identified 43 patients (32 women [74%]; mean age 79.4 yr) with isolated low-energy pelvic ramus fractures over the study period. The 1- and 5-year mortality rates were 16.3% (95% confidence interval [CI] 7.8%–30.3%) and 58.1% (95% CI 43.3%–71.6%), respectively, both significantly higher than the point estimates for the control group (6.6% and 31.3%, respectively). Following injury, 14/39 patients (36%) permanently required increased ambulatory aids, and 8 (20%) required a permanent increase in everyday level of care. Conclusion The results suggest that there may be increased mortality and morbidity following low-energy pattern pelvic ramus fractures in an older population compared to age- and sex-matched uninjured control subjects.

Abstract
Background Cnidii Rhizoma is the dried root stem of Cnidium officinale Makino. Cnidii Rhizoma (CR) has been used to treat menstrual irregularity, menstrual pain, and menopause in Korea. However, the effects and mechanisms of CR on RANKL-induced osteoclastogenesis pathway remain to be elucidated. In this study, we investigated the effects of CR on the inhibition of bone resorption of osteoclast and its mechanism RANK signaling pathway. Methods The anti-osteoclastogenesis of water extract of CR was measured using RAW 264.7 cell. Tartrate-resistant acid phosphatase (TRAP) assay, pit assay, reverse transcription polymerase chain reaction (RT-PCR) and western blot were performed. Moreover, the effects of CR were determined with an in vivo model using ovariectomized (OVX) rats. Results CR extract suppressed osteoclastogenesis, its activity and bone resorption activity through decreasing gene of osteoclast-related such as nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1), c-Fos, etc. Moreover, CR extract prevented the bone loss in OVX rats. Conclusion These results show that CR has a positive effect on menopausal osteoporosis by suppressing osteoclastogenesis.

Abstract
BACKGROUND Pelvic ring injuries in the elderly often occur after low-energy accidents. They may result in prolonged immobilization, complications and an intense rehabilitation process. The aim of this study was to assess mortality, physical functioning and quality of life (QoL) in elderly patients with pelvic ring injuries. METHODS A cross-sectional study was performed including all elderly patients (≥ 65 years) admitted for a pelvic ring injury between 2007-2016. Mortality and survival were evaluated and patient reported outcome measures (PROMs) were used to assess physical functioning (SMFA) and QoL (EQ-5D). These were compared to age-matched normative data from the general Dutch population. RESULTS A total of 153 patients, with a mean age of 79 years (SD 8) at the time of injury, were included in this study. The mortality rate was 20% at 30 days, 27% at 1 year and 41% at 3 years of follow-up. All six patients with a type C fracture died within 30 days. Analyses of the 153 patients showed that increasing age, fracture type C and Injury Severity Score (ISS) were all independent risk factors for mortality. Eventually, after excluding patients that died (N = 78) or were unable to contact (N = 2), 73 patients were eligible for follow-up, of which 53 patients (73%) responded. Mean Short Musculoskeletal Function Assessment (SMFA) scores were respectively 67.4 (function index), 65.2 (bother index), 66.5 (lower extremity), 60.4 (activities of daily living) and 68.2 (emotion). Mean EuroQuol-5D (EQ-5D) score was 0.72. Overall, physical functioning and quality of life were significantly decreased in comparison with normative data from the general population. CONCLUSION Elderly people who sustain a pelvic ring injury should be considered as a fragile population with substantial mortality rates. The patients who survived demonstrated a substantially lower level of physical functioning and quality of life in comparison with their age-matched peers from the general population. LEVEL OF EVIDENCE IV, therapeutic study.

Abstract
PURPOSE The incidence of low energy pelvic fractures (FPFs) in the elderly is increasing. Comorbidities, decreased bone-quality, problematic fracture fixation and poor compliance represent some of their specific difficulties. In the absence of uniform management, a standard operating procedure (SOP) was introduced to our unit, aiming to improve the quality of services provided to these patients. METHODS A cohort study was contacted to test the impact of (1) using a specific clinical algorithm and (2) using different antiosteoporotic drugs. Multivariate regression analysis was used to determine prognostic factors. Study endpoints were the time-to-healing, length-of-stay, return to pre-injury mobility, union status, mortality and complications. RESULTS A total of 132 elderly patients (≥65 years) admitted during the period 2012-2014 with FPFs were enrolled. High-energy fractures, acetabular fractures, associated trauma affecting mobility, pathological pelvic lesions and operated FPFs were used as exclusion criteria. The majority of included patients were females (108/132; 81.8%), and the mean age was 85.8 years (range 67-108). Use of antiosteoporotics was associated with a shorter time of healing (p = 0.036). Patients treated according to the algorithm showed a significant protection against malunion (p < 0.001). Also, adherence to the algorithm allowed more patients to return to their pre-injury mobility status (p = 0.039). CONCLUSIONS The use of antiosteoporotic medication in elderly patients with fragility pelvic fractures was associated with faster healing, whilst the adherence to a structured clinical pathway led to less malunions and non-unions and return to pre-injury mobility state.

Abstract
PURPOSE OF REVIEW Until recently, osteoporotic pelvic fractures have not been specifically studied. This review presents an update on epidemiological data of pelvic fracture, including morbidity, mortality and healthcare costs, the role of surgery and new data on sacroplasty in acute phase management. RECENT FINDINGS All studies underline the burden of osteoporotic pelvic fractures. Risk factors associated with these fractures are age, sex (women), and previous loss of autonomy. An increased mortality has been reported in all publications, similar to hip fracture for in-patient mortality and at 5 years of follow-up. Pelvic fractures often lead to transient or permanent autonomy loss, reflecting the high costs because of extended hospital stay, combined with nursing home requirement. However, recent studies report a decrease in the length of stay. Sacroplasty displays promising results to control pain and improve functional outcome. Early surgery begins to be discussed to also improve the outcome. SUMMARY Pelvic fractures display all the features of severe osteoporotic fractures: increased incidence, high morbidity, mortality, and healthcare costs that justify awareness of the practitioner on these fractures. Further studies on sacroplasty and surgery are necessary to improve pain control, functional improvement, thereby reducing the length of hospital stay and cost.

Abstract
OBJECTIVES Pelvic fractures are associated with increased risk of death among trauma patients. Studies show independent risks predicting mortality among patients with pelvic fractures vary across different geographic regions. This study analyses national data to determine predictors of mortality in initially stable adult pelvic trauma patients in the US. METHODS This study is a retrospective analysis of the US National Trauma Data Bank from January 2003 to December 2010 among trauma patients ≥18 years of age with pelvic fractures (including acetabulum). Over 150 variables were reviewed and analysed. The primary outcome was all-cause in-hospital mortality. Logistic regression analysis was used to determine independent risk factors predictive of in-hospital mortality in stable pelvic fracture patients. RESULTS 30,800 patients were included in the final analysis. Overall in-hospital mortality rate was 2.7%. Mortality increased twofold in middle aged patients (age 55-70), and increased nearly fourfold in patients with advanced age ≥70. We found patients with advanced age, higher severity of injury, Glasgow Coma Scale (GCS) <8, GCS between 9 and 12, prolonged mechanical ventilation, and/or in-hospital blood product administration experienced higher mortality. Patients transported to level 1 or level 2 trauma centres experienced lower mortality while concomitantly experiencing higher associated internal injuries. CONCLUSIONS Geriatric and middle aged pelvic fracture patients experience higher mortality. Predictors of mortality in initially stable pelvic fracture patients are advanced age, injury severity, mental status, prolonged mechanical ventilation, and/or in-hospital blood product administration. These patients might benefit from transport to local level 1 or level 2 trauma centres.

Abstract
Osteoclasts play a critical role in bone resorbing disorders such as osteoporosis, periodontitis, and rheumatoid arthritis. Therefore, discovery of agents capable of suppressing osteoclast differentiation may aid the development of a therapeutic access for the treatment of pathological bone loss. Ampelopsis brevipedunculata has been used as herbal folk medicine to treat liver diseases and inflammation in Asia. However, its effects on osteoclast differentiation are unknown. We were aimed to investigate the anti-osteoclastogenic activity in vitro and in vivo and to elucidate the underlying mechanism of Ampelopsis brevipedunculata extract (ABE). In this study, ABE inhibited receptor activator of NF-κB ligand (RANKL)-induced osteoclast differentiation, the formation of filamentous actin rings and the bone resorbing activity of mature osteoclasts. ABE inhibited RANKL-induced p38 and IκB phosphorylation and IκB degradation. Also, ABE suppressed the mRNA and protein expression of nuclear factor of activated T cells c1 (NFATc1) and c-Fos, and the mRNA expression of genes required for cell fusion and bone resorption, such as osteoclast-associatedreceptor (OSCAR), tartrate resistant acid phosphatase (TRAP), cathepsinK, dendritic cell-specific transmembrane protein(DC-STAMP), β3-integrin and osteoclast stimulatory transmembrane protein(OC-STAMP). Furthermore, results of micro-CT and histologic analysis indicated that ABE remarkably prevented lipopolysaccharide (LPS)-induced bone erosion. These results demonstrate that ABE prevents LPS-induced bone erosion through inhibition of osteoclast differentiation and function, suggesting the promise of ABE as a potential cure for various osteoclast-associated bone diseases.

Abstract
INTRODUCTION Injuries to the anterior or posterior pelvic ring rarely occur in isolation. Disruption to the anterior pelvic ring, indicated by a fracture of the superior or inferior pubic ramus, or injury to the pubic symphysis, may be indicative of additional pelvic ring disruption. The purpose of this retrospective study was to determine whether displaced inferior pubic ramus fractures warrant a more detailed investigation of the posterior ring in an effort to predict unstable posterior pelvic ring injuries. MATERIALS AND METHODS All patients with a displaced inferior ramus fracture on AP pelvic radiograph were identified at a single level I trauma center over a 5-year period. Complete pelvic radiographs and computed tomography scans were then evaluated for additional pelvic ring injuries. The data were analyzed using the chi-square test to determine the association between inferior ramus fractures and posterior pelvic ring injury. RESULTS Sixty-three of the 93 patients with a fracture of the inferior ramus (68 %) were found to have a posterior ring injury; 60 % of these injuries were unstable. Patients with concurrent superior ramus fractures were more likely to have a posterior ring injury (p < 0.001) and an unstable pelvis (p = 0.018). Of those with a displaced unilateral inferior ramus fracture, parasymphyseal involvement was associated with higher incidence of posterior ring injury (p = 0.047) and pelvic instability (p = 0.028). CONCLUSION The anterior pelvic ring can be used to help identify unstable injuries to the posterior pelvis. Patients with displaced inferior pubic ramus fractures warrant a detailed examination of their posterior ring to identify additional injuries and instability.
