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

[PMID: 39085304 PMCID: PMC11291645 DOI: 10.1038/s41598-024-68201-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 07/22/2024] [Indexed: 08/02/2024] Open
Abstract
To determine the presence of a consistent osseous corridor from the lateral-posterior aspect of the anterior inferior iliac spine to the sacral wing that could be used for safe trans percutaneous screw fixation for pelvic fragility fractures of the iliac wing and fracture dislocations of the sacroiliac joint (FFP types IIIa and IIIb). Computed tomography (CT) scans were obtained from 100 patients and imported to Mimics software for 3D reconstruction. Then, a cylinder was drawn to imitate the modified LC-II screw and adjusted to a maximum radius and length to obtain the feasible region. Thirteen parameters of the osseous corridor of the modified LC-II screw were measured. Differences between sex groups were compared, and significant statistical correlations were carefully studied to determine potentially important clinical relationships. The records of patients with FFP type IIIa and IIIb fragility fractures of the pelvis were extracted from our hospital. Patients who underwent modified LC-II screw fixation, LC-II screw fixation or reconstruction plate fixation were included. Patients' operative characteristics and complications were recorded at follow-up. Fracture reduction quality was assessed using the Matta standard. Functional outcomes were evaluated using the Majeed grading system. The mean maximum diameters of the osseous corridors of the modified LC-II screw in males and females were 12.73 and 10.83 mm, respectively. The mean maximum lengths of the osseous corridors of the modified LC-II screw in males and females were 96.37 and 93.37 mm, respectively. In the treatment of patients with FFP IIIa and FFP IIIb fractures, the group of treatment by the modified LC-II screws fixation was shown significantly shorter operative time and fewer intraoperative blood loss in comparison to that by the reconstruction plates. In the present study, all the males and females had a complete osseous corridor of the modified LC-II screw. The clinical results of the patients who were treated with modified LC-II screw fixation suggest that the novel method has a good preliminary outcome.

Abstract
Pubic rami fractures in the geriatric population are usually osteoporotic fractures resulting from low energy trauma and are characterized as stable injuries. Established treatment of these injuries is conservative, including rest, analgesic medication, and progressive active mobilization. These injuries are life-threatened when pubic rami fractures are accompanied by acute bleeding, either from an injury to a vessel (corona mortis) or from medication (anticoagulant or antiplatelet) for comorbidities, then. In this case study, we present the unusual case of an 82-year-old woman admitted to the emergency department 24 hours after a simple fall, causing nondisplacement osteoporotic pubic rami fracture, who, after 48 hours, developed a hematoma on the contralateral side of the pelvis, with progressive anemia and acute abdominal pain. This study has 2 objectives: to increase awareness of this life-threatening injury in the emergency department and to describe diagnosis and treatment modalities.

Comparison of the two surgery methods combined with accelerated rehabilitation in the treatment of lateral compression type 1 pelvic fractures in the elderly. J Orthop Surg Res 2023; 18:734. [PMID: 37759296 PMCID: PMC10537174 DOI: 10.1186/s13018-023-04219-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 09/19/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND Treating lateral compression type 1 (LC1) pelvic ring injuries in older patients is controversial. This study evaluated surgical treatments combined with ERAS for treating LC1 pelvic fractures in the elderly. METHODS In this retrospective study, patients who underwent surgery with INFIX (supra-acetabular spinal pedicle screws, and a subcutaneous connecting rod; the experimental group) or superior pubic ramus cannulated screw (the control group) fixation of LC1 pelvic fracture from January 2019 to January 2022 were reviewed. Injury radiography and computed tomography were performed to determine the Young-Burgess classification. All patients performed standardized early rehabilitation exercises after surgery and were followed up for > 12 months. After surgery, the Matta score and the visual analog scale (VAS) were evaluated, and the postoperative weight-bearing time and the length of stay (LOS) were recorded. The Barthel index and the Majeed score were evaluated at 4 months after surgery and at the last follow-up. RESULTS Fifty-three patients were included. Thirty-two patients included in the experimental group had a mean age of 75.0 ± 6.2 (range, 66-86) years, and the other 21 patients in the control group had a mean age of 74.6 ± 4.6 (range, 68-83) years. The mean follow-up time was 13.1 ± 1.6 (range, 12-18) months in the experimental group and 13.4 ± 1.3 (range, 12-16) months in the control group. There were no significant differences in follow-up time between the groups (P > 0.05). The mean VAS score, time to weight-bearing, and LOS were 2.0 ± 0.7 (range, 1-3), 1.1 ± 0.3 (range, 1-2) d, and 5.8 ± 0.9 (range, 4-7) d in the experimental group and 2.3 ± 1.2 (range, 1-5), 2.5 ± 1.6 (range, 1-7) d, and 6.1 ± 1.6 (range, 5-11) d in the control group, respectively. Between the two groups, there was a significant difference in the postoperative time to weight-bearing (P < 0.05), while there was no significant difference in the LOS (P > 0.05). No bedrest-related complications occurred in either group. The Matta score was 90.6% in the experimental group and 90.4% in the control group (P > 0.05). At the 4-months follow-up, the experimental group had a better Barthel index and Majeed score compared with the control group, which were 86.1 ± 6.2 (range, 70-95) vs. 81.2 ± 4.1 (range, 75-90) and 86.3 ± 3.3 (range, 78-91) vs. 80.3 ± 3.9 (range, 76-86), respectively. The experimental group had better early rehabilitation effect than the control group. There was no significant difference in Barthel index and Majeed score between the two groups at the last follow-up (P > 0.05). CONCLUSION Both INFIX and intramedullary superior pubic ramus cannulated screws can successfully treat LC1 pelvic fractures and reduce bed rest complications among older patients.

Abstract
A clear recommendation regarding treatment strategy of fragility fractures of the pelvic ring is missing. The most typical fracture pattern is a lateral compression type injury with non-displaced fractures of the anterior pubic rami and a unilateral os sacrum fracture (FFP II). We hypothesized that operative treatment would be superior to conservative treatment. From October 2017 to April 2020, a randomized prospective non-blinded trial with n = 39 patients was carried out. Two arms with 17 operative versus 22 conservative cases were created. Inclusion criteria were a posterior pelvic ring fracture FFP type II, age over 60 years and acute fracture (< 3 weeks). Barthel index, pain level (VAS), quality of life (EQ-5D-3L), and Tinetti-Gait Test were determined on admission, at discharge, and after 3, 6, 12 and 24 months. Median follow-up was 12.9 months. The Barthel index (= 0.325), VAS (p = 0.711), quality of life (p = 0.824), and Tinetti-Gait Test (p = 0.913) showed no significant differences between the two groups after 12 months. Two patients switched from the conservative to the operative arm due to persistent immobilization and pain. The one-year mortality rate showed no significant difference (p = 0.175). Our hypothesis that surgical treatment is superior was refuted. No significant benefit was shown in terms of quality of life, mortality and pain levels. The results suggest a more differentiated treatment approach in the future, with initial conservative treatment preferred. A larger multi-center trial is required to confirm these findings.Trial registration: The study was retrospectively registered with the German Clinical Trials Registry (DRKS00013703) on 10/12/2018.

Abstract
BACKGROUND Fragility fractures of the pelvis (FFPs) are osteoporotic pelvic fractures or insufficiency pelvic fractures caused by the low energy injury or stress fracture in daily livings in the elderly more than 60 years, which the incidence is increasing with the aging population in our country. FFPs result in considerable morbidity and mortality and as well as massive financial burden on the already strained health systems throughout the world. METHODS This clinical guideline was initiated by the Trauma Orthopedic Branch of Chinese Orthopedic Association; the External Fixation and Limb Reconstruction Branch of Chinese Orthopedic Association; the National Clinical Research Center for Orthopedics, Sports Medicine & Rehabilitation; Senior Department of Orthopedics of Chinese PLA general hospital; the Third Hospital of Hebei Medical University. The grading of recommendations assessment, development and evaluation (GRADE) approach and the reporting items for practice guidelines in healthcare (RIGHT) checklist were adopted. RESULTS 22 evidence based recommendations were formulated based on 22 most concerned clinical problems among orthopedic surgeons in China. CONCLUSION Understanding these trends through this guideline will facilitate better clinical care of FFP patients by medical providers and better allocation of resources by policy makers.

Abstract
OBJECTIVES Historically, pelvic ring fractures (PRF) are considered to occur predominantly in the anterior ring and therfore to be mechanically stable. Combined anterior and posterior (A + P) PRF are expected to be less mechanically stable and therefore to be associated with higher levels of pain and reduced mobility compared to isolated anterior fractures. The current study investigates the clinical relevance of combined A + P PRF in elderly patients. METHODS A prospective multicentre cohort study was conducted in patients >70 years of age with anterior PRF after low-energy trauma diagnosed on conventional radiographs. All patients underwent an additional CT-scan. Patients were divided into two groups; isolated anterior or combined A + P fractures. Patients were treated conservatively with adequate analgesia for at least one week. If patients could not be mobilised after conservative treatment, surgical fixation was performed. Numerical Rating Scale (NRS) pain scores, dependence on walking aids and Activities of Daily Living scores (ADL) were measured at 2-4 weeks, and 3, 6 and 12 months after fracture. RESULTS 102 patients (age 81.1 ± 7.6 years) were included. Isolated anterior fractures were diagnosed in 25 (24.5%) and A + P fractures in 77 (75.5%) patients. Baseline characteristics did not differ between the two groups. Most patients were successfully treated conservatively and 5 (4.9%) underwent percutaneous trans-iliac, trans-sacral screw fixation after failure of conservative treatment. At 2-4 weeks post trauma, patients with A + P fractures had similar median pain scores (3 (range 0-8) vs. 5 (0-10), p = 0.19) and ADL scores (85 (25-100) vs. 78.6 (5-100), p = 0.67), but were more dependent on walking aids (92.8% vs. 72.2%; p = 0.02) compared to patients with isolated anterior fractures. There were no significant differences at 3 months. At one year follow-up the median NRS pain and ADL scores for both fracture groups were 0 and 100, respectively. Mortality was 10.8%, and additional loss to follow-up was 17.6%. CONCLUSIONS The vast majority of elderly patients with PRF have combined A + P fractures. The clinical implications of additional posterior pelvic ring fractures in elderly patients appears to be limited.

Putzeys G, Dekeyser T, Garré P, Chesser T, Pottel H. 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.

[PMID: 36577845 DOI: 10.1007/s00198-022-06636-z] [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: 01/23/2022] [Accepted: 12/05/2022] [Indexed: 12/29/2022]
Abstract
UNLABELLED Incidence of pelvic and acetabular fracture is increasing in Europe. From 2007 to 2014 in the USA, this study found an age-adjusted incidence of 198 and 40 fractures/100,000/year, respectively, much higher than what has been described before. Incidence remained steady over that period and only a small increase in incidence of pelvic fracture in men was identified. PURPOSE To determine the incidence of pelvic ring and acetabular fractures in the USA over the period 2007-2014 and to examine trends over time. METHODS Retrospective population-based observational study using data from the Nationwide Emergency Department Sample (NEDS), a 20% stratified all-payer sample of US hospital-based emergency departments (EDs). All patients seen in the ED and diagnosed with pelvic/acetabular fracture from 2007 to 2014 were included. The primary outcome was age-adjusted incidence of pelvic and acetabular fractures per 100,000 persons/years. Secondary outcomes included incidence stratified by age and sex, patient- and hospital-related characteristics, and ED procedures. Tests for linear trends were used to determine if there were statistically significant differences by sex and age groups over time. RESULTS The age-adjusted incidence of pelvic fracture was 198 fractures/100,000/year, 323 in women and 114 in men. The age-adjusted incidence of acetabular fracture was 40 fractures/100,000/year, 36 in women and 51 in men. A small increase in the age-adjusted incidence of pelvic fracture in men was the only significant trend observed during the study time (p = 0.03). Over that period, the mean age of patients at presentation increased, as well as their number of comorbidities and associated fragility fractures, and they were more often sent home or to nursing facilities. CONCLUSIONS When considering all patients coming to the ED, not only those admitted to the hospital, adjusted incidence of pelvic and acetabular fracture is much higher than what has been described before. Contrarily to the global increase seen in other countries, incidence of pelvic and acetabular fractures dropped in the USA from 2007 to 2014 and only a small increase in age-adjusted incidence of pelvic fracture in men was identified.

[PMID: 36528424 DOI: 10.1016/j.injury.2022.12.007] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 12/04/2022] [Accepted: 12/07/2022] [Indexed: 12/14/2022]
Abstract
INTRODUCTION Pelvic fracture is a severe injury resulting in high mortality and disability rate, and brought heavy health burden. However, existing research conclusions only restricted to the national level while global estimation of pelvic fracture was lack. We aimed to estimate the global incidence, prevalence, and years lived with disability (YLDs) of pelvic fracture by region, age, gender, cause and sociodemographic index (SDI). MATERIALS AND METHODS Publicly available data was gained based on the Global Burden of Disease Study (GBD) 2019. We calculated the estimated annual percent change (EAPC) to analyze the temporal trends of pelvic fractures from 1990 to 2019. Incidence, prevalence and YLDs were analyzed by region, age, gender, cause and SDI. Spearman's rank order correlation was used to determine the correlation between SDI and incidence, prevalence and YLDs. RESULTS Globally, there were about 6 million incident cases, 18.8 million prevalent cases and 3.2 million YLDs cases of pelvic fractures for both sexes in 2019. The incidence number increased over 40% compared to 1990. However, the age standardized rate of incidence (ASIR) (EAPC = -0.22; 95% CI, -0.38 to -0.05), prevalence (ASPR) (EAPC = -0.42; 95% CI, -0.51 to -0.32) and YLDs (ASYR) (EAPC = -0.41; 95% CI, -0.50 to -0.32) all presented downward trends. Males had higher ASIR, ASPR and ASYR than females in each year from 1990 to 2019. The incidence, prevalence and YLDs rates were higher in males in early adulthood but exceeded in females at older age. A positive correlation was observed between ASIR and SDI (rho = 0.3732, p < 0.01). Regions with higher SDI tended to have higher ASIR, ASPR and ASYR than lower SDI regions. Falls and road injuries were the major causes of pelvic fracture at all ages and during the whole period. CONCLUSION The global health burden of pelvic fracture still remained high during the past thirty years. More policies and strategies are needed to face the challenge brought by population growth and aging.

Arch Orthop Trauma Surg 2023; 143:365-371. [PMID: 35041081 PMCID: PMC9886590 DOI: 10.1007/s00402-022-04346-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Accepted: 01/04/2022] [Indexed: 02/03/2023]
Abstract
In this investigation, it was assumed that it must be possible to visualize the intrapelvic aspect as accustomed by pelvic surgeons using the anterior intrapelvic (modified Stoppa) approach. Moreover, it was hypothesized, that plate mountings will not only be possible for the symphysis but also at the supra- and infrapectineal aspect as well as to the posterior column. Ten anonymized cadaveric specimens were included in this study. A standard laparoscopic totally extraperitoneal (TEP) approach was used. A total of 10 landmarks were defined that are usually within reach in the open anterior intrapelvic (AIP) approach. Moreover, five different plate mountings were tested. The locations were chosen in accordance with the indication spectrum suitable for open surgery through the traditional AIP approach. It was possible to gain intrapelvic visibility in seven of ten cases. In all of those seven cases, it was technically possible to place plates to the symphysis, superior pubic ramus, as well as longer anterior column plates up to the aspect posterior of the acetabulum. In the last four of the seven cases, it was possible to mount plates to the infrapectineal aspect as well as the posterior column, too. The team, previously trained in arthroscopic surgical techniques as well as pelvic trauma surgery, observed a steep learning curve. This investigation demonstrated, that endoscopic anterior intrapelvic plate osteosynthesis was feasible in the majority of the cases in a series of ten cadaveric models. New instruments will be needed such as extra-long rasp elevators, ball-spikes as well as devices to hold and position plates and extra-long self-holding screwdrivers. With these, endoscopic pelvic surgery will likely be a realistic option for selected pelvic trauma cases in the future.

Abstract
The study retrospectively determined the efficacy and safety of fixation of the pelvis (FFP) fragility fractures type IV using two tension band ilioiliac locking compression plates. Forty-one patients with FFP were treated in 2017-2020. 16 patients with FFP type IV, unable to walk weight-bearing, were treated by fixation using two tension band ilioiliac locking compression plates without fixing the anterior ring. Preoperatively and one year postoperatively, the functional outcome and performance were assessed using Pelvic Discomfort Index (PDI) and Timed Up and Go (TUG) test. Pre- and postoperative hemoglobin level was evaluated. Operation time and intra-and postoperative complications were documented. One year postoperatively, an X-ray was taken. The arithmetic mean (x) and standard deviations (±) of quantitative variables were calculated. T-test for dependent samples was used for pre-and postoperative results comparison. The PDI improved (p < 0.001) from x = 81.42 ± 4.04 to x = 36.19 ± 15.58. Preoperatively none of the patients was able to perform the TUG test. Postoperatively, the result exceeded x = 13.13 ± 3.99 s. The operation lasted x = 42.80 ± 8.90 min. Hemoglobin decreased (p < 0.001) from 11.63 ± 1.11 to 9.07 ± 1.21 g/dL. No complications nor fixation loosening were noted. The study support fixation using two tension band ilioiliac locking compression plates as an efficient and safe treatment of the FFP type IV.

Abstract
"Insufficiency fractures of the pelvis and acetabulum are occurring at increasing rates. Osteoporosis is the most prevalent risk fracture. Diagnosis begins with plain radiographs followed by advanced imaging with computed tomography and/or MRI. Pelvic ring fragility injuries are classified by the Fragility fractures of the pelvis system. Elderly acetabular fractures may be classified by the Letournel system. Management of these injuries is primarily nonoperative with early immobilization when allowed by fracture characteristics. When warranted, percutaneous fixation and open reduction internal fixation are options for both. Both acute and delayed total hip arthroplasty are options for acetabular fractures."

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

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

Abstract
» Primary osteoporosis is the most common cause of sacral insufficiency fractures (SIFs). Therefore, a multidisciplinary team approach is necessary for treatment of the fracture and the underlying biologic pathology, as well as prevention of future fragility fractures. » The presentation of SIFs typically includes lower back or buttock pain after a ground-level fall or without an identified trauma. Symptoms often have an insidious onset and are nonspecific; consequently, a delay in diagnosis and treatment is common. Clinicians need to have a high index of suspicion, particularly in high-risk patients. » Postmenopausal women who are >55 years of age are the most common demographic affected by SIFs. Other risk factors include osteoporosis, history of a prior fragility fracture, local irradiation, long-term corticosteroid use, rheumatoid arthritis, metabolic bone disorders, vitamin D deficiency, pregnancy, history of prior multilevel spinal fusion, and malignancy. » Typical imaging on computed tomography (CT) shows sclerosis of cancellous bone in the sacral ala, with or without a discrete fracture line or displacement. Magnetic resonance imaging is more sensitive than CT and shows hypointense signal on T1-weighted sequences and hyperintensity on T2-weighted or short tau inversion recovery sequences. » The treatment of SIFs is dependent on the severity of symptoms, fracture displacement, and instability of the pelvis. Accepted treatments include nonoperative rehabilitation, sacroplasty, iliosacral screw fixation, transsacral bar or screw fixation, transiliac internal fixation, and lumbopelvic fixation.

Abstract
Cement augmentation of sacroiliac (SI) screws in the posterior pelvic ring has been shown to provide greater biomechanical stability in cadaveric studies. Pelvic ring fractures are relatively rare compared to the total number of fractures. Nevertheless, the 1‑year mortality rate of up to 27% is very high, especially for geriatric pelvic ring fractures and is also largely associated with reduced mobility due to the fracture. The primary goal of treatment is therefore the restoration of patient mobility. This requires the achievement of sufficient stability of the pelvic ring. As osteoporosis is often a causative factor for the pelvic ring fracture, a more stable anchoring of the implants in the osteoporotic bone can be achieved by cement augmentation. This article presents the possibilities of cement augmentation of the pelvic ring and describes the technique of cement-augmented SI screws.

Abstract
INTRODUCTION Bone-specific alkaline phosphatase (BALP) has been a sensitive and reliable marker of bone metabolic activity. The study aimed to study the epidemiology of orthopaedic trauma patients and estimate the level of BALP in these patients. MATERIAL AND METHODS This hospital-based observational cross-sectional study was conducted on over 300 patients admitted to the orthopaedic trauma unit in the level I trauma centre of North India during the study period from January 2020 to January 2021. The level of BALP was assessed in serum samples of 258 patients. RESULT A total of 300 patients were included in this study, with an average age of 33.52±17.16 years. Road traffic accidents were the most common mode of injury among admitted patients. We found a significant linear correlation between age and mean BALP levels (P-value < 0.005). The mean age of patients having abnormal BALP is 63.0±16.61 years. Females (22.61±16.23) had greater mean BALP levels than males (13.15±5.86). Among different fractures, fractures around the hip had a higher mean BALP level (23.17±15.07). Patients with diabetes mellitus have higher mean BALP levels. CONCLUSION BALP is a cost-effective, readily available bone marker to assess the metabolic activity of orthopaedic trauma patients. Old age patients should undergo routine BALP estimation at admission to rule out metabolic disorders, and timely intervention will prevent complications associated with metabolic disorders.

Abstract
Objectives Fragility fractures of the pelvis (FFP) commonly occur in the frail elderly. Displacement in the posterior pelvic ring is recognized as the key sign of instability. This study aims to elucidate the relationship between computer tomography (CT)-based frailty markers and displacement of the posterior pelvic ring within 7 days after injury. Methods This retrospective study included 49 patients (42 females, 7 males) with FFP (type I 10, type II 24, type III 12, type IV 3). On a CT slice at the level of the third lumbar vertebra, skeletal muscle area, skeletal muscle radiation attenuation, and skeletal muscle index (SMI) were calculated as sarcopenia markers. Osteopenia was measured with trabecular region of interest attenuation technique on the same CT slice. Results There was no difference in the demographics between non-displaced and displaced FFP. CT-based data showed that patients with FFP had osteopenia. However, no difference was found between non-displaced and displaced FFP. SMI was higher in FFP types III/IV than non-displaced FFP when CT-based data on sarcopenia were compared among all patients. Female patients with FFP demonstrated similar results. Logistic regression analysis using the demographics and CT-based markers on sarcopenia and osteopenia revealed that SMI was a potential determinant of displacement of the posterior pelvic ring fractures. Conclusions There was inverse association between sarcopenia and displacement of the posterior pelvic ring in the early phase of FFP. Relatively preserved muscle may develop displacement in the elderly with osteopenia.

Abstract
BACKGROUND Recently, Rommens and Hoffman introduced a CT-based classification system for fragility fractures of the pelvis (FFP). Although fracture characteristics have been described, the relationship with clinical outcome is lacking. The purpose of this study was to get insight into the type of treatment and subsequent clinical outcome after all types of FFP. METHODS A cross-sectional cohort study was performed including all elderly patients (≥ 65 years) with a CT-diagnosed FFP, between 2007-2019 in two level 1 trauma centers. Data regarding treatment, mortality and clinical outcome was gathered from the electronic patient files. Patients were asked to complete patient-reported outcome measures (PROMs) regarding physical functioning (SMFA) and quality of life (EQ-5D). Additionally, a standardized multidisciplinary treatment algorithm was constructed. RESULTS A total of 187 patients were diagnosed with an FFP of whom 117 patients were available for follow-up analysis and 58 patients responded. FFP type I was most common (60%), followed by type II (27%), type III (8%) and type IV (5%). Almost all injuries were treated non-operatively (98%). Mobility at six weeks ranged from 50% (type III) to 80% type II). Mortality at 1 year was respectively 16% (type I and II), 47% (type III) and 13% (type IV). Physical functioning (SMFA function index) ranged from 62 (type III and IV) to 69 (type II) and was significantly decreased (P=<0.001) compared to the age-matched general population. Quality of life was also significantly decreased, ranging from 0.26 (type III) to 0.69 (type IV). CONCLUSIONS FFP type I and II are most common. Treatment is mainly non-operative, resulting in good mobility after six weeks, especially for patients with FFP type I and II. Mortality rates at one year were substantial in all patients. Physical functioning and quality of life was about 20-30% decreased compared to the general population.

[PMID: 34629169 DOI: 10.1016/j.injury.2021.09.044] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 09/20/2021] [Accepted: 09/26/2021] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The treatment of fragility fractures of the pelvis (FFP) is a challenge. The variations of non-operative- and of operative treatment are manifold and a structured treatment algorithm is lacking. The purpose of this study was to evaluate the outcome of elderly patients with a FFP who were treated with a therapeutic algorithm based on the FFP-classification. PATIENTS AND METHODS In a prospective cohort study 154 patients (mean age: 81.8 ±.61 (65-96); female: (86.8%; 131/154). BMI: 23.7 ±.34 (15-43)) with a FFP after inadequate mono trauma were treated according to a strict therapeutic algorithm between 04/2016 and 12/2018. According to a classification based on CT-scans either a standardized operative treatment or conservative therapy was induced and the outcome regarding objective measurements of mobility, pain, need for analgesics and mortality during hospital stay and after one year was analyzed. RESULTS 82/154 participants (53.2%) were assigned to the conservative treatment group and 72 participants (46.8%) to the operative treatment group. The overall one-year survival rate was 78.1% (118/151). The survival of the operative treatment group was 90.7% (49/54) and significantly higher than the survival of the conservative treatment group (74.7%; 56/75; p=.023). The one-year follow up showed a high dispersion of the pain level in the operatively treated patients and a significantly higher mean in comparison to conservatively treated patients. Both treatment groups showed increasing numbers of patients with unlimited mobilization but also immobile patients. Overall in 31.0% (18/58) of the operative participants and in 14.9% (14/93) of the non-operatively treated participants complications occurred (p=.04). CONCLUSION The strict compliance to the presented treatment algorithm of FFP with an operative strategy starting from FFP IIc leads to a significantly lower mortality within one year in comparison to the conservatively treated patients. The worst outcome and the highest mortality was seen in patients who refused the recommendation of operative stabilization. The results of this study justify to proceed with the strict classification dependent treatment algorithm and also support the early switch-over to operative treatment of patients with failed conservative therapy in FFP I to FFP IIb.

Effects of Loading Conditions on the Pelvic Fracture Biomechanism and Discrimination of Forensic Injury Manners of Impact and Run-Over Using the Finite Element Pelvic Model. APPLIED SCIENCES-BASEL 2022.

Abstract
This study aimed to systematically simulate the responses of pelvic fracture under impact and run-over to clarify the effects of boundary and loading conditions on the pelvic fracture mechanism and provide complementary quantitative evidence for forensic practice. Based on the THUMS finite element model, we have validated the simulation performance of the model by a real postmortem human pelvis side impact experiment. A total of 54 simulations with two injury manners (impact and run-over), seven loading directions (0°, 30°, 60°, 90°, 270°, 300°, 330°), and six loading velocities (10, 20, 30, 40, 50, and 60 km/h) were conducted. Criteria of effective strain, Von-Mises stress, contact force, and self-designed normalized eccentricity were used to evaluate the biomechanism of pelvic fracture. Based on our simulation results, it’s challenging to distinguish impact from run-over only rely on certain characteristic fractures. Loads on the front and back were less likely to cause pelvic fractures. In the 30°, 60°, 300° load directions, the overall deformation caused a “diagonal” pelvic fracture. The higher is the velocity (kinetic energy), the more severe is the pelvic fracture. The contact force will predict the risk of fracture. In addition, our self-designed eccentricity will distinguish the injury manner of impact and run-over under the 90° loads. The “biomechanical fingerprints” based on logistic regression of all biomechanical variables have an AUC of 0.941 in discriminating the injury manners. Our study may provide simulation evidence and new methods for the forensic community to improve the forensic identification ability of injury manners.

Abstract
UNLABELLED Pelvic fracture patients were randomized to blinded daily subcutaneous teriparatide (TPTD) or placebo to assess healing and functional outcomes over 3 months. With TPTD, there was no evidence of improved healing by CT or pain reduction; however, physical performance improved with TPTD but not placebo (group difference p < 0.03). INTRODUCTION To determine if teriparatide (20 μg/day; TPTD) results in improved radiologic healing, reduced pain, and improved functional outcome vs placebo over 3 months in pelvic fracture patients. METHODS This randomized, placebo-controlled study enrolled 35 patients (women and men >50 years old) within 4 weeks of pelvic fracture and evaluated the effect of blinded TPTD vs placebo over 3 months on fracture healing. Fracture healing from CT images at 0 and 3 months was assessed as cortical bridging using a 5-point scale. The numeric rating scale (NRS) for pain was administered monthly. Physical performance was assessed monthly by Continuous Summary Physical Performance Score (based on 4 m walk speed, timed repeated chair stands, and balance) and the Timed Up and Go (TUG) test. RESULTS The mean age was 82, and >80% were female. The intention to treat analysis showed no group difference in cortical bridging score, and 50% of fractures in TPTD-treated and 53% of fractures in placebo-treated patients were healed at 3 months, unchanged after adjustment for age, sacral fracture, and fracture displacement. Median pain score dropped significantly in both groups with no group differences. Both CSPPS and TUG improved in the teriparatide group, whereas there was no improvement in the placebo group (group difference p < 0.03 for CSPPS at 2 and 3 months). CONCLUSION In this small randomized, blinded study, there was no improvement in radiographic healing (CT at 3 months) or pain with TPTD vs placebo; however, there was improved physical performance in TPTD-treated subjects that was not evident in the placebo group.

Abstract
Fragility fractures of the pelvis (FFP) and fragility fractures of the sacrum (FFS), which are emerging in the geriatric population, exhibit characteristics that differ from those of pelvic ring disruptions occurring in the younger population. Treatment of FFP/FFS by a multidisciplinary team can be helpful in reducing morbidity and mortality with the goal of reducing pain, regaining early mobility, and restoring independence for activities of daily living. Conservative treatment, including bed rest, pain therapy, and mobilization as tolerated, is indicated for treatment of FFP type I and type II as loss of stability is limited with these fractures. Operative treatment is indicated for FFP type II when conservative treatment has failed and for FFP type III and type IV, which are displaced fractures associated with intense pain and increased instability. Minimally invasive stabilization techniques, such as percutaneous fixation, are favored over open reduction internal fixation. There is little evidence regarding outcomes of patients with FFP/FFS and more literature is needed for determination of optimal management. The aim of this article is to provide a concise review of the current literature and a discussion of the latest recommendations for orthopedic treatment and management of FFP/FFS.

Minimally Invasive "Crab-Shaped Fixation" for Treating Patients with Fragility Fractures of the Pelvis. Spine Surg Relat Res 2021; 5:425-430.

Abstract
Introduction In the aging society, fragility fracture of the pelvis (FFP) has become a problem. Although strong and minimally invasive fixation is required in FFP surgery, reports on relevant surgical results are scarce. Crab-shaped fixation (CSF) is a spinopelvic fixation that involves reconstruction of the posterior pelvic ring using spinal instrumentation. This study aimed to evaluate the walking ability and perioperative complications of patients who underwent CSF for FFP. Methods We included patients diagnosed with unstable FFPs, including sacral fracture, who required hospitalization. Demographic data, such as age, sex, bone mineral density, and Rommens classification, were evaluated. Surgical findings included estimated blood loss, operation time, and perioperative complications. The improvement in postoperative walking ability was evaluated based on the length of the postoperative period before the initiation of walker training and whether walking aids were required at 6 months post-surgery, compared with those who received conservative treatment for FFP. Results Our study included 6 cases that received CSF and 16 cases that received conservative treatment, in which all were females and presented with sacral fractures. The average age of the surgical patients, the operation time, and the estimated blood loss were 79.5±14.7 years, 180.7±28.7 min, and 124.2±29.4 mL, respectively. The average length of the postoperative period prior to the initiation of walker training was 10.8±12.3 days, which was significantly shorter than that of conservative treatment. With regard to perioperative complications, poor reduction of fracture dislocation was observed in one case as well as surgical site infection in another case, but the walking ability improved in all cases. Conclusions We evaluated the results of the posterior pelvic ring reconstruction with CSF for patients with vertically unstable FFPs, including sacral fractures. CSF is minimally invasive and would be useful as it allowed walker training during the early postoperative period, which improved patients' walking ability even during the in situ pelvic ring reconstruction.

Geriatr Orthop Surg Rehabil 2021; 12:21514593211058969.

Abstract
Background Hip fractures are well researched in orthogeriatric literature. Equivalent investigations for fragility-associated periprosthetic and periosteosynthetic femoral, ankle joint, pelvic ring, and rib fractures are still rare. The purpose of this study was to evaluate mortality, functional outcome, and socioeconomic parameters associated to the upper-mentioned fragility fractures prospectively in a 2-year follow-up. Methods Over the course of a year, all periprosthetic and periosteosynthetic femoral fractures (PPFF), ankle joint fractures (AJ), pelvic ring fractures (PR), and rib fractures (RF), that were treated on a co-managed orthogeriatric ward, were assessed. Parker Mobility Score (PMS), Barthel Index (BI), place of residence, and care level were recorded. After 2 years, patients and/or relatives were contacted by mailed questionnaires or phone calls in order to calculate mortality and reevaluate the mentioned parameters. Results Follow-up rate was 77.7%, assessing 87 patients overall. The relative mortality risk was significantly increased for PR (2.9 (95% CI: 1.5–5.4)) and PPFF (3.5 (95% CI: 1.2–5.8)) but not for RF (1.5 (95% CI: 0.4–2.6)) and AJ (2.0 (95% CI: 0.0–4.0)). Every fracture group except AJ showed significantly higher BI on average at follow-up. PMS was, respectively, reduced on average for PR and RF insignificantly, but significantly for PPFF and AJ in comparison to pre-hospital values. 10.0–27.3% (each group) of patients had to leave their homes permanently; care levels were raised in 30.0–61.5% of cases. Discussion This investigation provides a perspective for further larger examinations. PR and PPFF correlate with significant increased mortality risk. Patients suffering from PPFF, PR, and RF were able to significantly recover in their activities of daily living. AJ and PPFF conclude in significant reduction of PMS after 2 years. Conclusion Any fragility fracture has its impact on mortality, function, and socioeconomic aspects and shall not be underestimated. Despite some fractures not being the most common, they are still present in daily practice.

Abstract
BACKGROUND Increasing numbers of posterior pelvic ring fractures, especially in elderly patients, demonstrate the need for soft tissue protecting surgical techniques. Standard of care is iliosacral screw osteosynthesis. This type of osteosynthesis has its limitations especially in patients with reduced bone properties. Therefore, the development of new and straightforward surgical techniques and implant designs is favorable. METHODS Introducing this modular system for the posterior pelvic ring, known complications of iliosacral screw osteosynthesis, such as implant loosening and malpositioning may be reduced, due to innovative mechanical characteristics. RESULTS The shown cases demonstrate the potential benefits of the system with a wide range of treatment options due to its modularity. CONCLUSION The modular implant system presented here can significantly facilitate and improve the stabilization of posterior pelvic ring instabilities.

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.

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 Although pubic ramus fractures are common in the elderly, resultant hemodynamic instability is a rare complication. The corona mortis, a vascular anastomosis between the obturator vessels and the external iliac vessels in the retropubic space, is occasionally damaged by fractures of the pubic ramus, causing significant hemorrhage. The purpose of this study was to evaluate the incidence and anatomical position of the corona mortis on the anteroposterior and inlet views. METHODS Sixty-one cadavers (122 hemipelvizes) were dissected and the incidence of the corona mortis was evaluated. Photographs were then taken simulating anteroposterior and inlet radiographs, and labeled as the anteroposterior and inlet views. The distance from the pubic symphysis to the corona mortis was measured on each of the two views. RESULTS The corona mortis was present in 76.1% of hemipelvizes. The corona mortis traverses along the periosteum of the dorsal surface of the pubis. The incidence of arterial corona mortis was 28.3% and that of venous corona mortis was 76.1%. The distance from the superior margin of the symphysis pubis to the corona mortis measured 47.7 ± 9.9 (45.9-49.6) mm on the anteroposterior view, and 59.4 ± 9.2 (57.3-61.5) mm on the inlet view. CONCLUSIONS In order to predict possible hemodynamic instability of the corona mortis following pubic ramus fractures, it is of clinical significance to precisely establish the anatomical position of the corona mortis on the anteroposterior and inlet views.

Abstract
Surgical treatment of fragility sacrum fractures with percutaneous sacroiliac (SI) screw fixation is associated with high failure rates. Turn-out is detected in up to 20% of the patients. The aim of this study was to evaluate a new screw-in-screw implant prototype for fragility sacrum fracture fixation. Twenty-seven artificial hemipelvises were assigned to three groups (n = 9) for instrumentation of an SI screw, the new screw-in-screw implant prototype, ora transsacral screw. Before implantation, a vertical osteotomy was set in zone 1 after Denis. All specimens were biomechanically tested to failure in upright position. Validated setup and test protocol were used for complex axial and torsional loading applied through the S1 vertebral body to promote turn-out of the implants. Interfragmentary movements were captured via optical motion tracking. Screw motions were evaluated by means of triggered anteroposterior X-rays. Interfragmentary movements and implant motions were significantly higher for SI screw fixation compared to both transsacral and screw-in-screw fixations. In addition, transsacral screw and screw-in-screw fixations revealed similar construct stability. Moreover, screw-in-screw fixation successfully prevented turn-out of the implant that remained during testing at 0° rotation for all specimens. From biomechanical perspective, fragility sacrum fracture fixation with the new screw-in-screw implant prototype provides higher stability than an SI screw, being able to successfully prevent turn-out. Moreover, it combines the higher stability of transsacral screw fixation with the less risky operational procedure of SI screw fixation and can be considered as their alternative treatment option.

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
PURPOSE In Bangladesh the incidence of pelvic fracture is increasing day by day due to suboptimal roads and heavy traffic. However, there is no epidemiological study of these injuries in Bangladesh. Our aim was to study the epidemiology of patients admitted with pelvic fractures at two tertiary care hospital in Dhaka, Bangladesh. METHODS This was a prospective study carried out on trauma patients with pelvic fracture at two level 1 trauma care center of two tertiary care hospital in Dhaka, Bangladesh. The study period was from July 2015 to June 2019 (48 months). Patient's data including demography of patients, mechanism of injuries, fracture types, associated injuries, method of treatment, post-operative complications, length of hospital stay were recorded according to a unified protocol. RESULTS The study population was comprised of 696 patients, where 556 (79.88%) were male and 140 (20.12%) were female. Mean age was 37.75 years and road traffic accidents were the most common mode of injuries. Lateral compression fractures were the most common injuries and Urethral injuries were the most common associated injuries. Death was the outcome in 3.5% of the cases due to high energy trauma. CONCLUSION This study revealed that pelvic fractures were significantly more frequent in men. Most frequent cause was road traffic accident. The majority of these cases did not required surgery. Mortality was associated with high velocity trauma with severe injuries.

Abstract
INTRODUCTION Osteoporosis-related fragility fractures of the pelvic ring (FFP) differ fundamentally from pelvic fractures in younger patients. However, very little is known about biomechanical stability of different osteosynthesis procedures addressing the anterior pelvic ring in these fractures. The aim of this study was to compare standard external fixation with internal fixation using a novel screw-and-rod system in osteoporotic fractures of the pelvic ring in terms of stiffness, plastic deformation and maximum load under cyclic loading in a human cadaveric model. MATERIALS AND METHODS A total of 18 embalmed osteoporotic cadaver pelvis specimens were randomized based on the T-score into a group for external fixation and a group for internal fixation. FFP type-IIB fractures were created. In addition to the external or internal fixator, a cement-augmented sacroiliac screw was implanted. Afterwards, axial cyclic loading was performed in a testing setup simulating one-leg stand. RESULTS Mean plastic deformation and stiffness both were significantly better in the internal fixation group than in the external fixation group (plastic deformation: 0.37 mm (SD: 0.23) versus 0.71 mm (SD: 0.26), p = 0.011; stiffness: 43.69 N/mm (SD: 18.39) versus 26.52 N/mm (SD: 9.76), p = 0.029). Maximum load did not differ significantly between internal fixator (506.3 N; SD: 129.4) and external fixator (461.1 N; SD: 147.4) (p = 0.515). CONCLUSIONS Submuscular internal fixation might be an interesting alternative to external fixation in clinical practice because of better biomechanical properties as well as several advantages in clinical use.

Abstract
OBJECTIVE The purpose of this study was to evaluate the types and the frequency of fractures, both in the pediatric and adult population during the COVID-19 pandemic and to find out the differences in comparison to the non-pandemic period. METHODS Patients who were admitted to the hospital with a new fracture during pandemic period (March 16 to May 22, 2020) were evaluated. Control group consisted of patients with new fractures admitted to the hospital in the same date range in 2018 and 2019. The patients were divided into two groups as ≤16 years old (group 1) and >16 years old (group 2). The evaluation was based on the age and gender of the patients and localization of the fractures. Hospitalized and surgically treated patients were evaluated as well. RESULTS A total of 1794, 1747, and 670 fractures were observed in 2018, 2019, and 2020, respectively. Mean age of the patients in group 1 was found to have decreased in the pandemic period (p<0.001). The most common fracture sites in the pediatric population were the distal forearm and distal arm, whereas hand, distal forearm, and foot were most common fracture sites in adults, in both pandemic and non-pandemic periods. The proportional increase in femoral and tibial shaft fractures in group 1, and toe, tibial shaft, and metacarpal fractures in group 2 was found to be statistically significantly (p<0.05). In group 1; 6.8%, 7.7%, and 14.6% of the fractures were treated surgically in 2018, 2019, and 2020, respectively (p<0.001). For group 2, these rates were 20.1%, 18.6%, and 18.1%, respectively (p=0.67). There were 48, 29, and 26 open fractures in 2018, 2019 and 2020, respectively (p=0.066). In pandemic period, duration of the hospital stay was significantly shorter for distal humerus and proximal femur fractures (p values= 0.001 and 0.017, respectively). CONCLUSION We observed that the frequency of fractures decreased by approximately one-third during the pandemic period compared with that in the non-pandemic period. The mean age of the patients with a fracture in the pediatric group was found to have decreased also. Finger fractures in pediatric patients and metatarsal fractures in adult patients were found to have significantly decreased during the pandemic. LEVEL OF EVIDENCE Level III, Diagnostic study.

Abstract
INTRODUCTION There are no universally accepted treatment strategies for fragility fractures of the pelvis (FFPs). The incidence of delayed union or non-union of Type IIIa FFP is still unknown. PRESENTATION OF CASE We describe a case of delayed union of a Type IIIa FFP. A 96-year-old female patient who lives independently accidentally fell when exiting a car. The diagnosis of Type IIIa FFP with displaced left ilium and left pubic rami fracture. Surgical repair was performed using an anterior intrapelvic approach with constructs made using two reconstruction contoured plates to bridge the medial edge and middle part of the fracture. This case was revealed delayed union. The periodic CT examinations were performed to determine the progress of bone union. The patient returned to most social activities including living independently and the Modified Majeed score was 94 at 12 months post-operation. DISCUSSION For the case of TypeⅢa FFP, soft tissue is spread over a wide area. When the fracture site of ilium was exposed, the cortical bone was found to be thin with poor blood flow. There is a possibility that the blood flow was hindered by subperiosteal elevation of the iliacus muscle from the internal iliac fossa in this case. CONCLUSION Non-union of the iliac wings is relatively rare following high-energy pelvic ring fractures. The incidence of delayed union or non-union of Type IIIa FFP remains unknown; therefore, careful follow-up of patients who undergo treatment is necessary to reduce the risk of delayed union.

Abstract
Introduction: Life-threatening hemorrhage associated with low-energy pelvic fracture has been described in single cases in the literature. However, there is limited evidence available on the bleeding risk associated with hemodynamically stable osteoporotic pelvic fractures. The objective of this study was to estimate the bleeding risk associated with low-energy osteoporotic pelvic fractures in the elderly population. Materials and Methods: A retrospective review of patients aged > 65 years old with pelvic fractures admitted between 2015 and 2018 was performed. Eighty-two patients were identified: 12 males and 70 females with a median age of 86 years. The median Charlson comorbidity index was 6 (interquartile range = 5-7). Eighty-one fractures were classified as lateral compression I or Tile A2, and 1 fracture was classified as lateral compression II or Tile B2. Forty patients were on concurrent anticoagulation treatment. In 4 patients on warfarin, this treatment was reversed on admission. Results: The mean hemoglobin (Hb) level on arrival was 12.36 g/dL (±1.67 g/dL). There were significant drops in Hb levels on day 1 (Hb = 11.22 ± 1.86 g/dL, P < .001) and day 4 (Hb = 10.97 ± 1.6 g/dL, P < .001). Nine percent of patients required a blood transfusion. The mean baseline Hb level pre-transfusion was 8.33 g/dL (±1.15). Preexisting anticoagulation treatment did not predispose patients to greater decreases in Hb levels on day 1 (mean difference = 0.16 g/dL, P = .62) or day 4 (mean difference = 0.29 g/dL, P = .48) post-admission. Discussion: An observed mean decrease in Hb level of up to 1.4 g/dL can occur in hemodynamically stable elderly patients with osteoporotic pelvic fractures, reflecting an approximate loss of 1.4 units of packed red blood cells. Conclusion: This degree of decrease in Hb may be clinically significant in geriatric patients with chronic anemia and a history of cardiovascular disease.

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
The 3D image enhancer-adjusted percutaneous triangular stabilization of geriatric pelvic ring fractures avoids implant-associated perioperative complications. Displaced fractures of the posterior pelvic ring require stable instrumentation to enable solid bony fusion in a balanced alignment and to control the risk of neurological and vascular damage. This is mandatory in high-energy injuries in young patients and especially in low-energy injuries of geriatric patients. Various surgical techniques have been established. The triangular stabilization technique shows the best biomechanical results. The percutaneous instrumentation reduces access-related morbidity and provides all the benefits of minimally invasive surgery. In order to avoid implant-associated complications, such as vascular and nerve injuries, anatomical and radiological principles are indispensable. The use of 3D image enhancement ensures a safe instrumentation. Nevertheless, pitfalls have to be considered. This article presents the technique of percutaneous triangular stabilization using the 3D scan. After percutaneous insertion of the guide wires into the L4 vertebral body, the iliac bone and transiliosacrally under 2D X‑ray control, the correct wire position is verified by the 3D scan. Then, screws are inserted and the instrumentation is completed in a standard fashion. Using this technique implant-associated perioperative complications, such as nerve and vascular damage due to screw misplacement can be reduced.

Abstract
Introduction: Lateral compression type 1 (LC1) pelvic ring fractures make up 63% of all pelvic ring
injuries. This fracture pattern is typically seen in older patients. The purpose of this
study is to assess the ambulatory status of individuals sustaining LC1 fractures at
long-term follow-up and what specific characteristics, if any, effect this status or
functional outcomes. Methods: Over a 2-year period, all pelvic ring injury at 2 hospitals within one academic
institution was queried. One hundred sixty-one low-energy LC1 pelvic fractures were
identified. Results: Fifty patients were available for long-term outcomes (mean: 36 months). Long-term
functional outcomes (mean follow-up: 36 months) as measured by SMFA subgroup scores were
demonstrated to be 3 times higher in patients currently using assistive devices for
walking (P = .012). Increased age (P = .050) was
associated with the continued use of assistive walking devices. Of the patients who did
not use an ambulatory device prior to LC1 injury, 5 (11.6%) sustained a fall or medical
complication within 30 days of the index pelvic fracture; this was associated with the
current use of an assistive ambulatory device (P = .010). Forty-three
(86%) patients didn’t use an assistive ambulatory device prior to sustaining the LC1
fracture. Seven (14%) patients utilized assistive devices both before and after the LC1
injury. Thirteen (26%) patients, who did not utilize assistive ambulatory devices prior
to their injury, necessitated them at long-term follow-up. Discussion: Surgeons should be aware of these associations, as they can implement early
interventions aimed at patients at risk, for assistive device use, following LC1 pelvic
fractures. Conclusion: More than a quarter of the patients sustaining an LC1 pelvic fracture continue to use
an aid for ambulation at long-term follow-up. Older age, complications, and falls within
30 days of this injury are associated with the utilization of an assistive ambulatory
device.

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

Biomechanical analysis of anterior pelvic ring fractures with intact peripelvic soft tissues: a cadaveric study. Eur J Trauma Emerg Surg 2019; 47:187-193. [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
Pelvic ring fractures are rare injuries in the elderly though the incidence is increasing due to the increasing age of the population. Main goal of treatment is the quickest possible re-mobilization to prevent side-effects of immobilization such as osteopenia, pulmonary infections or thromboembolic events. Isolated anterior pelvic ring fractures are stable injuries and therefore they usually can be treated conservatively, while pelvic ring injuries with involvement of the posterior ring are considered unstable and should undergo surgical stabilization if the patient’s condition allows for it. Conservative treatment includes adequate analgesia, guided mobilization with partial weight bearing if possible and osteoanabolic medication. The appropriate surgical procedure should be discussed in an interdisciplinary round considering patient’s pre-injury condition, anaesthetic and surgical risks.

Abstract
INTRODUCTION Several different systems of classification have been developed to understand the complexity of pelvic ring fractures, to facilitate communication between physicians and to support the selection of appropriate therapeutic measures. The purpose of this study was to measure the inter- and intraobserver reliability of Tile AO, Young and Burgess, and FFP classification in pelvic ring fractures. The Rommens classification system (FFP) is analyzed for the first time. MATERIALS AND METHODS Four reviewers (2 × senior pelvic trauma surgeon, 1 × resident, 1 × medical student) separately analyzed and classified 154 CT scans of patients with pelvic fracture. The Tile AO, the Young and Burgess, and the FFP classifications (subgroup with patients ≥ 60 years) were compared. Another blinded re-evaluation was carried out after 2 months to determine intraobserver reliability. RESULTS The overall interobserver agreement was fair for all classification systems (ICC: OTA 0.55, Young and Burgess 0.42, FFP 0.54). For specific categories, (e.g. type B or C fractures), there was a substantial agreement between the experienced surgeons (kappa: OTA 0.64, Young and Burgess 0.62, FFP 0.68). For inexperienced observers, there was a fair agreement in all systems (kappa: OTA 0.23, Young and Burgess 0.23, FFP 0.36). CONCLUSIONS All three classifications reach their maximum reliability with advanced expertise in the surgery of pelvic fractures. The novel FFP classification has proved to be at least equivalent when directly compared to the established systems. The FFP classification system showed substantial reliability in patients older than 60 years.

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
Fragility fractures of the pelvis are occurring with increasing frequency. These fractures, occurring in the geriatric patient population, are low-energy injuries and are dissimilar in many ways from those caused by high-energy trauma. For example, the mechanism of injury is different and emergency treatment is usually not necessary. Having diminished bone strength, fragility fracture lines follow areas of low bone mineral density and loss of pelvic stability may increase over time. Based on our clinical experience, we propose a comprehensive classification of pelvic fragility fractures separate from the existing pelvic ring injury classification to provide a framework for distinguishing the different fragility fracture types and their recommended treatment. This classification is derived first from the degree of fracture instability, followed by the location of the fracture. Anterior pelvic fractures are differentiated from posterior pelvic ring fractures, nondisplaced fractures from displaced, and unilateral from bilateral. It is our belief that this new in-depth analysis of these lesions will assist the clinician in identifying the specific patterns of fragility fracture instability and selecting the appropriate choice of treatment. Further investigation is required to determine the ultimate value of this proposed pelvic fragility fracture classification system. LEVEL OF EVIDENCE:: Diagnostic Level V.

Abstract
BACKGROUND The objective of the study is to investigate the load transmission within the pelvic ring under physiological loading during gait and to correlate these results with clinical findings. In a second approach, we analysed how load distribution is altered by fractures of the anterior pelvic ring. METHODS Muscle forces and joint reaction forces are calculated by inverse dynamics and implemented in a finite element pelvis model including the joints. RESULTS With the intact configuration and according to the moment of the gait, left and right superior and inferior rami show the highest stresses of the model, corresponding to the typical location of an anterior pelvic ring fracture. A superior ramus fracture induces larger stresses to the lower ramus and a slight increase of stresses on the posterior structures. A total disruption of anterior rami redirects the loads to the back of the pelvis and introduces significantly higher stresses on the posterior structures. CONCLUSIONS This investigation enhances the understanding of the biomechanics of the pelvis and highlights the important role of the rami in load carrying and in maintaining integrity of the pelvic ring.

Abstract
OBJECTIVES To document in-hospital and 1-year mortality rates after high-energy pelvic fracture in patients 65 years of age or older as compared to a younger cohort. DESIGN Retrospective review. SETTING Urban Level 1 academic trauma center. PATIENTS Seventy consecutive patients 65 years of age and older treated for pelvic fracture resulting from high-energy mechanism from 2008 to 2011. A total of 140 patients 18-64 years of age were matched to the study population based on mechanism of injury and OTA Code 61 subtype for comparison. INTERVENTION Review of demographics, injury characteristics, hospital management, and mortality. MAIN OUTCOME MEASUREMENTS Mortality. RESULTS The overall inpatient mortality rate was 10%. The older cohort exhibited an inpatient mortality rate 3 times higher than the younger cohort (18.6% vs. 5.7%, P = 0.003). There was no difference in mortality 1 year post discharge (5.3% vs. 3.8%, P = 0.699). No significant differences in initial Glasgow Coma Scale or Injury Severity Score were identified (GCS 12.9 vs. 12.4, P = 0.363; ISS 24.7 vs. 23.4, P = 0.479). Multivariate analysis identified the Charlson Comorbidity Index (CCI) (P = 0.012) and Abbreviated Injury Scale (AIS)-chest (P = 0.005) as independent predictors of in-hospital mortality, and CCI (0.005) and AIS-abdomen (0.012) for 1-year mortality. CONCLUSIONS After controlling for mechanism of injury and pelvic fracture classification, we found that adults ≥65 and those with multiple comorbidities were more likely to die in the hospital than younger adults. However, mortality within 1-year postdischarge was low and did not differ between groups. This is in sharp contrast to the high rates of postdischarge mortality observed in elderly patients with a hip fracture. LEVEL OF EVIDENCE Prognostic Level III.

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