RESUMEN

INTRODUCTION: We aimed to investigate secondary fracture and mortality rates, and risk factors in patients with proximal femoral fractures. MATERIALS AND METHODS: We conducted a multicenter prospective cohort study on female patients with proximal femoral fractures who underwent surgical treatment between April 2020 and March 2021. Postoperative follow-ups were performed at 6-, 12-, 18-, and 24-month intervals to determine the secondary fracture and mortality rates, and the risk factors and its influence were examined. RESULTS: Of the 279 registered patients, 144 patients (51.6%) were diagnosed with very high fracture risk osteoporosis. The postoperative osteoporosis rate exceeded 96%; however, osteoanabolic agents were used sparingly. The risk factor of both secondary fracture and mortality was very high fracture risk osteoporosis, and secondary fractures within 12 months were markedly occurred. Secondary fracture rates increased as the number of matched very high fracture risk osteoporosis criteria increased. Notably, secondary fractures and mortality were recorded in 21.4% and 23.5% of the patients who met all criteria, respectively. CONCLUSION: Over half of the female patients with proximal femoral fractures had very high fracture risk osteoporosis. Although, very high fracture risk osteoporosis demonstrated a notably increased risk of secondary fractures, particularly at 12 months post-surgery, the use of osteoanabolic agents was substantially low. Collectively, our findings highlight the need to consider the risk of very high fracture risk osteoporosis, expand the use of medications to include osteoanabolic agents, and reconsider the current healthcare approach for proximal femoral fractures.

RESUMEN

BACKGROUND: Teriparatide, a recombinant parathyroid hormone, is pivotal in osteoporosis treatment, particularly in post-surgical recovery for hip fractures. This study investigates its efficacy in functional recovery post-hip fracture surgery in elderly patients, a demographic particularly susceptible to osteoporotic fractures. METHODS: In this retrospective cohort study, 150 elderly patients with proximal femoral fractures undergoing open reduction and internal fixation were enrolled. They were categorized into two groups: receiving 20 µg of daily teriparatide injections for 18 months and receiving standard antiresorptive medications during a 24-month follow-up. Detailed records of patient demographics, Fracture Risk Assessment Tool scores, and comorbidities were kept. Key outcomes, including bone mineral density (BMD) and functional scores (Barthel Index and Visual Analog Scale for hip pain), were evaluated at 3 and 24 months post-surgery. RESULTS: Out of the original cohort, 126 patients (20 men and 106 women with an average age of 85.5 ± 9.3 years) completed the study. The teriparatide group exhibited significant enhancements in both functional scores and BMD when compared to the control group. Notably, functional improvements were less pronounced in male patients compared to female patients. Additionally, the incidence of new fractures was markedly lower in the teriparatide group. CONCLUSION: Administering teriparatide daily for 18 months post-surgery for proximal femoral fractures significantly benefits very elderly patients by improving functionality and bone density, with observed differences in recovery between genders. These results reinforce the efficacy of teriparatide as a potent option for treating osteoporosis-related fractures in the elderly and highlight the importance of considering gender-specific treatment and rehabilitation strategies.

RESUMEN

PURPOSE: To evaluate the mortality rate, intensive care unit (ICU) referral, and Charlson comorbidity index (CCI) between different types of vaccinated and non-vaccinated patients operated on due to intertrochanteric femoral fracture (IFF) during the pandemic. METHODS: Ninety-six patients (43 males, 53 females) who had proximal femur nails (PFN) for the IFF during the pandemic were included in the study. The patients were divided into four subgroups; non-vaccinated, and different types of vaccinated. Mortality rates, ICU referrals, and CCI relations were evaluated. RESULTS: No significant difference was observed in terms of demographic data such as age, gender, side, CCI, and ICU referrals between the subgroups (p = 0.164, p = 0.546, p = 0.703, p = 0.771, p = 0.627 respectively). The mortality rate was significantly lower in the Sinovac + BioNTech subgroup (p = 0.044). CONCLUSION: No relationship was found between mortality rate, ICU referral, and CCI in different types of vaccinated and non-vaccinated patient subgroups.

RESUMEN

INTRODUCTION: The primary aim of this study was to evaluate the clinical and radiological outcomes after surgical treatment of proximal femoral fractures utilizing the Proximal Femoral Nail Antirotation (PFNA), with the main focus on complications and reoperations. The secondary aim was to compare the outcomes of patients with and without cement augmentation of the cephalomedullary nails. MATERIALS AND METHODS: All patients with an acute proximal femoral fracture consequently treated with a PFNA between January 2011 and Dezember  2018 were evaluated. Clinical and radiological data were assessed for intra- and postoperative complications, including treatment failure. In addition, intra- and postoperative radiographs were used to determine the position of the implant, and any migration, via Tip-Apex-Distance (TAD) and the caput-collum-diaphyseal angle (CCD). The accuracy of the fracture reduction was rated according to Baumgaertners criteria. RESULTS: Two hundred sixty-four consecutive patients (mean age 78.8 ± 12.0; 73.1% female) were included. The predominant OTA/AO fracture classification was 31A1 (153 cases, 58.0%). The average duration of surgery was 63.1 ± 28.0 min and showed no significant differences between PFNA and PFNA with augmentation. The implant positioning was rated as good in 222 cases (84.1%). Two hundred sixty-three patients (99.6%) showed evidence of healing within the time frame of three months postoperatively, one case of delayed union healed after secondary dynamization. During the observational period, 18 patients (6.8%) required a total of 23 additional surgeries. Overall, a lower reoperation rate was observed following the use of the augmentation option (2/86 patients (2.3%) vs. 16/178 patients (9.0%), p = 0.04). In particular, there were no cases of cut-out or cut-through among patients who underwent augmentation as part of osteosynthesis. CONCLUSIONS: Overall reoperation rate after surgical treatment of proximal femoral fractures utilizing the Proximal Femoral Nail Antirotation (PFNA) was 6.8%, with 23 additional surgeries performed in 18 patients. The usage of the PFNA with augmentation showed equally good implant positioning, excellent healing rates and fewer postoperative complications compared to the PFNA implant alone with a similar overall duration of surgery.

RESUMEN

The aim of this study is to present the results of single-stage total hip arthroplasty (THA) after Dynamic Hip Screw (DHS) failure, or secondary posttraumatic osteoarthrosis. From 2003 to 2020, 15 THAs were performed in group of 15 patients for the treatment of DHS failure, or for late complications following femoral neck and pertrochanteric fractures. The mean follow-up period after arthroplasty was 46.9 months (range 7-139). The patients were evaluated retrospectively-both clinically and radiographically, focussing on the demography, infection rate and other complications (revision surgery), during the year 2023. 9 males and 6 females were included in the study, with a mean age of 56.5 years (range 29-93) at the time of primary osteosynthesis. Each of them had proximal femoral fracture treated primarily with a DHS and then late one-stage revision surgery, with hardware removal and THA implantation. The median time between DHS osteosynthesis and THA was 41.2 months (range 4-114). Four patients (26.6%) had complications after THA, with the need for revision in two cases (13.3%). Dislocation rate was 6.6% (one case), with the need for repeated-revision of THA. The infection rate was 6.6% (one patient) with the need for revision of THA. Peroperative periprosthetic femoral fracture was observed in 13.3% (two patients) without any other problems. Six patients (40%) died during the follow-up period. Single-stage total hip arthroplasty with concomitant hardware removal bears a high- mortality rate, with a higher incidence of postoperative complications compared to elective THA.

RESUMEN

This study evaluated the incidence rates and societal burden of hip fractures in The Netherlands. Although incidence in the elderly population is decreasing and hospital stay is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population. PURPOSE: The aim of this nationwide study was to provide an overview of the incidence rate and economic burden of acute femoral neck and trochanteric fractures in The Netherlands. METHODS: Data of patients who sustained acute proximal femoral fractures in the period January 1, 2000, to December 31, 2019, were extracted from the National Medical Registration of the Dutch Hospital Database. The incidence rate, hospital length of stay (HLOS), health care and lost productivity costs, and years lived with disability (YLD) were calculated for age- and sex-specific groups. RESULTS: A total of 357,073 patients were included. The overall incidence rate increased by 22% over the 20-year study period from 16.4 to 27.1/100,000 person-years (py). The age-specific incidence rate in elderly > 65 years decreased by 16% (from 649.1 to 547.6/100,000 py). The incidence rate in men aged > 90 has surpassed the incidence rate in women. HLOS decreased in all age groups, hip fracture subtypes, and sexes from a mean of 18.5 to 7.2 days. The mean health care costs, over the 2015-2019 period, were lower for men (€17,723) than for women (€23,351) and increased with age to €26,639 in women aged > 80. Annual cumulative costs reached €425M, of which 73% was spent on women. CONCLUSION: The total incidence of hip fractures in The Netherlands has increased by 22%. Although incidence in the elderly population is decreasing and HLOS is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population.

RESUMEN

INTRODUCTION: We aimed to investigate the secondary fracture rates and risk factors in patients with proximal femoral fractures using fracture liaison service (FLS) during the coronavirus disease (COVID)-19 pandemic. MATERIALS AND METHODS: In this multi-center prospective cohort study, patients with proximal femoral fractures who were treated surgically at three hospitals from April 2020 to March 2021 were included. Follow-up examinations at 6 and 12 months postoperatively were conducted to investigate the clinical data and ascertain whether osteoporosis treatment could be continued. RESULTS: A total of 316 patients with proximal femoral fractures were registered. During the follow-up period, 17 patients died and 67 patients could not visit the hospitals owing to the COVID-19 pandemic. In total, 172 patients who could be followed-up 12 months postoperatively were examined using dual-energy X-ray absorptiometry during hospitalization; underwent postoperative osteoporosis treatment, mainly with bisphosphonates (89.5%); and were administered medications continuously. Secondary fractures occurred within 1 year in 14 patients (8.1%). Multivariate analysis showed that patients who used sleeping pills and had a lower functional independence measure had an increased risk for developing secondary fractures. CONCLUSION: During the COVID-19 pandemic, secondary fractures can be prevented if the patients can be followed and osteoporosis treatment can be continued. Conversely, despite adequate osteoporosis drug examination and treatment, a certain number of secondary fractures still occurred. The finding that postoperative osteoporosis therapy using routine medications and rehabilitation is associated with secondary fractures may support the importance of establishing clinical standards consisting of a multidisciplinary collaboration for FLS.

RESUMEN

BACKGROUND: The risk of proximal femoral fractures increases with aging, causing significant morbidity, disability, mortality and socioeconomic pressure. The aims of the present work are (1) to investigate the epidemiology and incidence of these fractures among the elderly in the Region of Lombardy; (2) to identify the factors influencing survival; (3) to identify the factors influencing hospitalization and post-operative costs. METHODS: The Region of Lombardy provided anonymized datasets on hospitalized patients with a femoral neck fracture between 2011 and 2016, and anonymized datasets on extra-hospital treatments to track the patient history between 2008 and 2019. Statistical evaluations included descriptive statistics, survival analysis, Cox regression and multiple linear models. RESULTS: 71,920 older adults suffered a femoral fracture in Lombardy between 2011 and 2016. 76.3% of patients were females and the median age was 84. The raw incidence of fractures was stable from year 2011 to year 2016, while the age-adjusted incidence diminished. Pertrochanteric fractures were more spread than transcervical fractures. In patients treated with surgery, receiving treatment within 48 h reduced the hazard of death within the next 24 months. Combined surgical procedures led to increased hazard in comparison with arthroplasty alone, while no differences were observed between different arthroplasties and reduction or fixation. In patients treated conservatively, age and male gender were associated with higher hazard of death. All patients considered, the type of surgery was the main factor determining primary hospitalization costs. A higher number of surgeries performed by the index hospital in the previous year was associated with financial savings. The early intervention significantly correlated with minor costs. CONCLUSIONS: The number of proximal femoral fractures is increasing even if the age-adjusted incidence is decreasing. This is possibly due to prevention policies focused on the oldest cohort of the population. Two policies proved to be significantly beneficial in clinical and financial terms: the centralization of patients in high-volume hospitals and a time limit of 48 h from fracture to surgery. TRIAL REGISTRATION: Non applicable.

RESUMEN

BACKGROUND: Tranexamic acid (TXA) has long been the antifibrinolytic hemostatic drug of choice for orthopedic surgery. In recent years, the hemostatic effect of epsilon aminocaproic acid (EACA) has gradually been recognized by orthopedic surgeons and has begun to be used in hip and knee arthroplasty with little mention of the comparison of these two drugs; Therefore, this study compared the efficacy and safety of EACA and TXA in the perioperative period of elderly patients with trochanteric fractures to verify whether EAC could be a "qualified alternative" to TXA and to provide theoretical support for the clinical application of TXA. METHODS: Two hundred and forty-three patients who received proximal femoral nail antirotation (PFNA) for trochanteric fractures from January 2021 to March 2022 at our institution were included and divided into the EACA group (n = 146) and the TXA group. (n = 97) determined by the drugs used in the perioperative period The main observations were blood loss and blood transfusion.The second second outcome was blood routine, coagulation, Hospital complications and complications after discharge. RESULTS: The perioperative EACA patients had significantly lower significant blood loss (DBL) than the TXA group (p < 0.0001) and statistically significant lower C-reactive protein in the EACA group than in the TXA group on postoperative day 1 (p = 0.022). Patients on perioperative TXA had better postoperative day one (p = 0.002) and postoperative day five erythrocyte width than the EACA group (p = 0.004). However, there was no statistically significant difference between the two groups in the remaining indicators in both drugs: blood items, coagulation indicators, blood loss, blood transfusion, length of hospital(LOH), total hospital expense, and postoperative complications (p > 0.05). CONCLUSION: The hemostatic effects and safety of EACA and TXA in the perioperative application of trochanteric fractures in the elderly are essentially similar, and EACA can be considered for use as an alternative to TXA, increasing the flexibility of physicians to use it in the clinical setting. However, the limited sample size included necessitated a high-quality, large sample of clinical studies and long-term follow-up.

RESUMEN

Hip fractures are a serious public health issue with major consequences, especially for frail community dwellers. This study found a poor prognosis at 6 months post-trauma with regard to life expectancy and rehabilitation to pre-fracture independency levels. It should be realized that recovery to pre-trauma functioning is not a certainty for frail community-dwelling patients. INTRODUCTION: Proximal femoral fractures are a serious public health issue in the older patient. Although a significant rise in frail community-dwelling elderly is expected because of progressive aging, a clear overview of the outcomes in these patients sustaining a proximal femoral fracture is lacking. This study assessed the prognosis of frail community-dwelling patients who sustained a proximal femoral fracture. METHODS: A multicenter retrospective cohort study was performed on frail community-dwelling patients with a proximal femoral fracture who aged over 70 years. Patients were considered frail if they were classified as American Society of Anesthesiologists score ≥ 4 and/or a BMI < 18.5 kg/m2 and/or Functional Ambulation Category ≤ 2 pre-trauma. The primary outcome was 6-month mortality. Secondary outcomes were adverse events, health care consumption, rate of institutionalization, and functional recovery. RESULTS: A total of 140 out of 2045 patients matched the inclusion criteria with a median age of 85 (P25-P75 80-89) years. The 6-month mortality was 58 out of 140 patients (41%). A total of 102 (73%) patients experienced adverse events. At 6 months post-trauma, 29 out of 120 (24%) were readmitted to the hospital. Out of the 82 surviving patients after 6 months, 41 (50%) were unable the return to their home, and only 32 (39%) were able to achieve outdoor ambulation. CONCLUSION: Frail community-dwelling older patients with a proximal femoral fracture have a high risk of death, adverse events, and institutionalization and often do not reobtain their pre-trauma level of independence. Foremost, the results can be used for realistic expectation management.

RESUMEN

BACKGROUND: Treatment of pertrochanteric femoral fractures is often associated with significant blood loss. It has already been demonstrated that the administration of tranexamic acid (TXA) for endoprosthetic procedures reduces blood losses and leads to a decreased frequency of postoperative complications. The aim of this study is to demonstrate whether the administration of TXA as part of osteosynthesis treatment for pertrochanteric fractures using a proximal femoral nail reduces perioperative blood losses and haemorrhage-related complications. METHODS: In a two-centre retrospective cohort study, 1 g TXA i.v. was administered preoperatively to 294 patients who had suffered from pertrochanteric femoral fractures. The subjects were compared clinically to a historical control group who did not receive TXA (nonTXA). Outcomes were evaluated on the basis of perioperative blood loss, transfusion requirement, and occurrence of complications. RESULTS: The TXA group showed evidence of a reduction in blood loss (TXA = 0.97 ± 0.47 l; nonTXA = 1.06 ± 0.47 l; p = 0.004) and a lower frequency of transfusion (TXA = 20%; nonTXA = 31%; p = 0.032) as compared to the nonTXA group. However, evidence of this therapeutic effect could only be demonstrated at one of the centres on subgroup comparison between the two centres. At the second centre, the data did not show a significant difference. A trend could be seen towards a reduction in postoperative renal failure. No complications occurred resulting from the administration of tranexamic acid. CONCLUSION: Preoperative administration of TXA does not lead to an increased rate of thromboembolic complications when applied for treatment of pertrochanteric femoral fractures. Evidence of a positive effect could be seen in principle in relation to the reduction in perioperative blood loss and the frequency of transfusion. The difference in effect between the two centres remains to be clarified: for this reason, it is possible to assume that further factors influencing the efficacy of TXA administration are at play which were not taken into account in this study.

RESUMEN

BACKGROUND: Intraoperative proximal femoral fractures (IPFF) are relevant complications during total hip arthroplasty. Fixation using cerclage wires (CW) represents a minimally-invasive technique to address these fractures through the same surgical approach. The goal of treatment is to mobilise the patient as early as possible, which requires high primary stability. This study aimed to compare different cerclage wire configurations fixing IPFF with regard to biomechanical primary stability. METHODS: Standardised IPFF (type II, Modified Mallory Classification) were created in human fresh frozen femora and were fixed either by two or three CW (1.6 mm, stainless steel). All cadaveric specimens (n = 42) were randomised to different groups (quasi-static, dynamic) or subgroups (2 CW, 3 CW) stratified by bone mineral density determined by Dual Energy X-ray Absorptiometry. Using a biomechanical testing setup, quasi-static and dynamic cyclic failure tests were carried out. Cyclic loading started from 200 N to 500 N at 1 Hz with increasing peak load by 250 N every 100 cycles until failure occurred or maximum load (5250 N) reached. The change of fracture gap size was optically captured. RESULTS: No significant differences in failure load after quasi-static (p = 0.701) or dynamic cyclic loading (p = 0.132) were found between the experimental groups. In the quasi-static load testing, all constructs resisted 250% of the body weight (BW) of their corresponding body donor. In the dynamic cyclic load testing, all but one construct (treated by 3 CW) resisted 250% BW. CONCLUSIONS: Based on this in vitro data, both two and three CW provided sufficient primary stability according to the predefined minimum failure load (250% BW) to resist. The authors recommend the treatment using two CW because it reduces the risk of vascular injury and shortens procedure time.

RESUMEN

BACKGROUND: Reverse oblique intertrochanteric fractures are classified by the AO/OTA as 31A3 and account for 2-23% of all trochanteric fractures. The Gamma 3-Proximal Femoral Nail (GPFN) and the Expendable Proximal Femoral Nail (EPFN) are among the various devises used to treat this fracture. The aim of this study was to compare outcomes and complication rates in patients with AO/OTA 31A1-3 fractures, treated by either a GPFN or an EPFN. PATIENTS AND METHODS: A total of 67 patients (40 in the GPFN group and 27 in the EPFN group, average age 78.8 years) were treated in our institution between July 2008 and February 2016. Data on postoperative radiological variables, including peg location and tip-apex distance (TAD), as well as orthopedic complications, such as union rate, surgical wound infection and cut-outs rates were also recorded, along with the incidence of non-orthopedic complications and more surgical data. Functional results were evaluated and quantified using the Modified Harris Hip Score (MHHS) and by the Short Form 12 Mental Health Composite questionnaire (SF-12 MHC) in order to assess the quality of life. RESULTS: The total prevalence of postoperative orthopedic complications including postoperative infection showed a significant difference with a p-value of 0.016 in favor of the EPFN group. Nonetheless, the frequency of revision did not differ between the two groups, being 0.134. The main orthopedic complication in both groups was head cut-out of the GPFN lag screw and the EPFN expendable peg, which was 20% and 7.4%, respectively, and required a revision surgery using a long nail or total hip replacement (THR). However, the average TAD did not significantly differ between groups which might be due to a relatively low cohort to reach a significant difference. Nonunion rate of 5% occurred solely in the GPFN group, with similar results of intraoperative open reduction between both groups. The EPFN group achieved better scores in both questionnaires (p = 0.027 and p = 0.046, respectively). Both the MHHS and SF-12 MCS values significantly differed between groups, with the EPFN group achieving better scores than the GPFN group in both questionnaires (p = 0.027 and p < 0.05, respectively). CONCLUSIONS: According to this study, the EPFN yields better results in comparison with the GPFN, with relatively less complications rate, for the treatment of unstable reverse oblique pertrochanteric fracture. In light of this results, we conclude that the EPFN might be as good as GPFN for the treatment of reverse oblique intertrochanteric fractures. LEVEL OF EVIDENCE: Level III retrospective study. The local institutional review board of the Tel Aviv Medical Center approved this study and all the surgeries were done exclusively in this institution.

RESUMEN

PURPOSE: Epidemiological and clinical parameters according to the Parker-Palmer Index (PPI) have not been specifically studied as predictors of re-fracture time in patients over 65 years old with contralateral hip fracture. The main purpose of this study was to assess whether these parameters could represent a prognostic factor in this population. METHODS: This retrospective study included all consecutive patients older than 65 years that suffered from a proximal femoral fracture, 31 according to Association for Osteosynthesis/Orthopaedic Trauma Association classification, treated at our unit between Feb 1st 2019 and Feb 1st 2020. RESULTS: This study enrolled 387 patients. Thirty-seven of them had already incurred a contralateral hip fracture: seven males and 30 females. The median time between the first and second hip fractures was 3.5 years. This study revealed that increasing age (p = 0.003), male sex (p = 0.029) and a PPI value ≥ 5 between the first and second hip fracture (p = 0.015) are risk factors associated with a contralateral hip fracture in the first three years after the first episode. There were no statistically significant differences regarding anti-osteoporotic therapy and the anatomic site of the first hip fracture episode. CONCLUSION: The results of the present study suggest that several risk factors have a crucial role in hip re-fracture time in patients over 65 years old.

RESUMEN

The software of 3D-Modeling(UG NX 10.0) was used to design a new external fixator model for proximal femoral fracture, and fresh femoral cadaver specimens were used to simulate experimental operation. The results showed that the external fixator designed with the proximal femoral locking plate shape can improve the accuracy of Kirschner wire penetration into the femoral neck, reduce fluoroscopic and soft tissue incision injuries, and make a good stability and is easy to operate, which has a certain value for patients with proximal femoral fracture, such as intolerant surgery and poor physical condition.

RESUMEN

PURPOSE: A focused hip MRI (FHMR) for the detection of radiographically occult hip fractures was implemented in our emergency department (ED) in 2013. The goal of this study was to assess the clinical utility of this protocol. METHODS: We retrospectively reviewed radiology reports of 262 unique patients who underwent 263 FHMR (coronal T1, coronal STIR, axial T2 fat saturated) for suspected hip fracture in the ED from October 2013 to March 2020. Electronic medical records were reviewed for the ED course, follow-up imaging, and clinical management within 90 days. RESULTS: Seventy-one patients had one or more fractures identified by FHMR: one-third had proximal femoral fractures; two-third had pelvic fractures. Of these 71 patients, 53 (74%) had radiographically occult fractures, including 14 (20%) with occult proximal femoral fractures; 4 patients had fractures occult on CT. Nineteen patients with a suspected fracture on radiography were found to have no fracture on FHMR. Four fractures not reported on FHMR were later seen on follow-up imaging: these included 1 isolated greater trochanter, 1 additional ischial tuberosity, 1 additional superior pubic ramus, and 1 additional sacrum. All four fractures were treated non-operatively. Muscle/tendon injury was the most common type of injury, seen in 50% (130/262) patients with the most commonly torn tendons being the hamstring (44%; 15/34) followed by gluteus medius tendon (18%; 6/34). A full-hip or pelvis MRI was done after FHMR in only 5 patients, primarily for the purpose of better characterizing findings already identified on FHMR (2 for fracture, 2 for tendon injury, 1 for soft tissue metastasis). Only one of these five studies provided new information: ruling out a previously questioned fracture. Clinical management of the vast majority of patients was based solely on findings from the FHMR. CONCLUSIONS: FHMR offers reliable identification of radiographically occult hip fractures and muscle/tendon injuries. The protocol is well trusted in guiding patient management in our ED.

RESUMEN

INTRODUCTION: Hip replacement for pertrochanteric femoral fractures (PF) is challenging due to its complexity. Studies regarding this procedures are limited, therefore this monocentric study was conducted. The null hypothesis was no effect between replacement and internal fixation according to revision and mortality. MATERIAL AND METHODS: Using an electronic database, patients who had received a hip replacement between 2007 and 2016 for a PF with a concomitant coxarthrosis were included in the study. The comparison group consisted of 1000 osteosyntheses for the treatment of PF. With the exception of coxarthrosis, the same inclusion and exclusion criteria were defined. Surgical revision and mortality with endpoint 2 years after the operation were the primary outcomes. At least 2 years postoperatively, a telephone follow-up was done with living patients who underwent replacement. RESULTS: Records of 90 hip replacements and 15 baseline characteristics were reviewed (e.g., age, sex, body mass index, preoperative blood values, ASA classification, dementia, fracture classification). Replacement was significantly associated with a delay to operation (p < 0.001), a longer duration of operation (p < 0.001), an increased blood loss (p < 0.001), more blood transfusions (p < 0.001), and a longer inpatient stay (p = 0.026). According to the primary outcome, the mortality rate (p = 0.002) and the rate of infection in a subgroup analysis (p = 0.031) were also significantly increased. Using Cox regression, replacement was associated with a significantly higher probability of a shorter survival rate (odds ratio: 1.438, confidence interval: 1.054-1.962). Therefore, the null hypothesis was rejected. At the follow-up 6.1 years postoperatively (3.2-8.6 years), only 17 patients with replacement (20%) were still alive. The mean Parker mobility score was 5.0 points (range 3-9 points). CONCLUSION: In this study, a significantly higher rate of infection and mortality was observed in patients with hip replacement for a PF and with a concomitant coxarthrosis; compared to osteosynthesis of PF without coxarthrosis. Further studies are mandatory to provide the appropriate treatment for patients with this fracture pattern.

RESUMEN

BACKGROUND: Proximal femoral fractures are a major socioeconomic burden and they occur mainly in geriatric patients. High mortality and complication rates are reported. To reduce the mortality and morbidity of these patients, co-management with geriatricians has been recommended. Most previous studies have focused on relatively comprehensive care models. Models with only a few additions to the usual care have not been extensively evaluated. METHODS: This retrospective observational study included all patients aged ≥70 years (mean age: 84.5 ± 7.1 years, 70% women) with an isolated proximal femoral fracture treated surgically in our institution from May 2018 to October 2019. In the first 9 months, patients were treated with the usual care (control group, n = 103). In the second 9 months, patients were treated with our multidisciplinary care model (intervention group, n = 104), which included the usual care, plus: (1) one multidisciplinary ward round per week and (2) one "elective" operation slot per day reserved for proximal femoral fractures. Baseline characteristics and outcome measures of the hospital stay were extracted from electronic health records. A 3-month follow-up was conducted by phone. RESULTS: Baseline characteristics were comparable between groups (p > 0.05). The hospital stay was shorter in the intervention group than in the control group (7.8 ± 4.3 vs. 9.1 ± 4.5; p = 0.022). The intervention reduced the waiting time for surgery by more than 10 h (intervention: 25.4 ± 24.5 vs. control: 35.8 ± 34.1 h; p = 0.013). A structured phone interview was not performed in 30.9% of the cases. The model reduced the overall dissatisfaction rate by more than half (12.9% vs. 32.4%; p = 0.008). On the other hand, the groups had similar perioperative complication rates (25% vs. 24.3%; p > 0.9999) and mortality (4.8% vs. 3.9%; p > 0.9999) and they remained similar at the 3-month follow-up (complications: 20.3% vs. 17.6% p = 0.831, mortality: 18.2% vs. 15.0% p = 0.573). CONCLUSION: We found that two additions to the usual proximal femoral fracture regimen could significantly improve the overall satisfaction rate, reduce the length of hospital stay and shorten the waiting time for surgery. In contrast to previous studies, we observed no significant improvements in complication or mortality rates. Further changes in the standard care might be needed for this purpose.

RESUMEN

Approximately 50% of all hip fractures are extracapsular and typically treated with extramedullary or intramedullary fixation. Modern intramedullary nails used for internal fixation of extracapsular fractures are generally cephalomedullary nails secured by at least one cephalic screw. Different designs have been developed, varying in length, diameter, neck shaft angle, number of cephalic screws or blades, ability to slide and/or compress, ability to control rotation, construction materials and insertion-point. Articles published in all languages up to January 2019, are listed in PubMed and Scopus electronic databases about the association between the number of cephalic screws and the rate of complications and functional outcome. Twenty articles were included following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Sliding hip screws (SHS) were the standard of care for hip fractures from the 1950s to the 1990s, but presently intramedullary nails are more commonly used. There has been a more than 20-fold relative increase in the utilization of intramedullary nails since 1999. With the emergence of value-based healthcare, there is a growing interest of how best to provide high-quality care in a clinical and cost-effective manner, acknowledging limited healthcare budgets. The present systematic review assessed the long-term outcomes of the most commonly used nails using double cephalic screws compared with single screw devices in patients with unstable intertrochanteric fractures. The development of new technologies may allow a lower incidence of complications, a reduction in operative time and a lower intraoperative blood loss.

RESUMEN

BACKGROUND: Proximal femoral fractures are strongly associated with morbidity and mortality in elderly patients. Mortality is highest among frail institutionalized elderly with both physical and cognitive comorbidities who consequently have a limited life expectancy. Evidence based guidelines on whether or not to operate on these patients in the case of a proximal femoral fracture are lacking. Practice variation occurs, and it remains unknown if nonoperative treatment would result in at least the same quality of life as operative treatment. This study aims to determine the effect of nonoperative management versus operative management of proximal femoral fractures in a selected group of frail institutionalized elderly on the quality of life, level of pain, rate of complications, time to death, satisfaction of the patient (or proxy) and the caregiver with the management strategy, and health care consumption. METHODS: This is a multicenter, observational cohort study. Frail institutionalized elderly (70 years or older with a body mass index < 18.5, a Functional Ambulation Category of 2 or lower pre-trauma, or an American Society of Anesthesiologists score of 4 or 5), who sustained a proximal femoral fracture are eligible to participate. Patients with a pathological or periprosthetic fractures and known metastatic oncological disease will be excluded. Treatment decision will be reached following a structured shared decision process. The primary outcome is quality of life (Euro-QoL; EQ-5D-5 L). Secondary outcome measures are quality of life measured with the QUALIDEM, pain level (PACSLAC), pain medication use, treatment satisfaction of patient (or proxy) and caregivers, quality of dying (QODD), time to death, and direct medical costs. A cost-utility and cost-effectiveness analysis will be done, using the EQ-5D utility score and QUALIDEM score, respectively. Non-inferiority of nonoperative treatment is assumed with a limit of 0.15 on the EQ-5D score. Data will be acquired at 7, 14, and 30 days and at 3 and 6 months after trauma. DISCUSSION: The results of this study will provide insight into the true value of nonoperative treatment of proximal femoral fractures in frail elderly with a limited life expectancy. The results may be used for updating (inter)national treatment guidelines. TRIAL REGISTRATION: The study is registered at the Netherlands Trial Register (NTR7245; date 10-06-2018).
