Project description:ObjectivesThe increasing number of hip arthroplasties (HA), due to the growing elderly population, is associated with the risk of femoral periprosthetic fractures (FPFs). The purpose of this study was to identify potential risk factors for the development of FPFs after HA.MethodsA systematic review was conducted in five data bases (Medline, Embase, Cochrane, Cinahl, ICTRP) according to the Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) guidelines up to May 2019, using the key words "risk factor," "periprosthetic fracture," and "hip replacement or arthroplasty." Meta-analysis of the clinical outcomes of HA and subgroup analysis based on the factors that were implicated in FPFs was performed.ResultsSixteen studies were included (sample size: 599,551 HA patients, 4253 FPFs, incidence 0.71%). Risk factors statistically associated with increased incidence of FPFs were female gender (+ 40%), previous revision arthroplasty surgery (× 3 times), and the presence of rheumatoid arthritis (× 2.1 times), while osteoarthritis (- 57%), cement application (- 59%), and insertion of Biomet (- 68%) or Thompson's prosthesis (- 75%) were correlated with low prevalence of FPFs. Obesity, cardiac diseases, advanced age, bad general health (ASA grade ≥ 3), and use of Exeter or Lubinus prosthesis were not linked to the appearance of FPFs.ConclusionThis meta-analysis suggested that female gender, rheumatoid arthritis, and revision arthroplasty are major risk factors for the development of FPFs after a HA. In those patients, frequent follow-ups should be planned. Further prospective studies are necessary to clarify all the risk factors contributing to the appearance of FPFs after HA.

Project description:BackgroundPeriprosthetic joint infection (PJI) is a catastrophic complication after total hip arthroplasty (THA). Our meta-analysis aimed to identify the individual-related risk factors that predispose patients to PJI following primary THA.MethodsComprehensive literature retrieval from Pubmed, Web of Science, and the Cochrane Library was performed from inception to Feb 20th, 2021. Patient-related risk factors were compared as per the modifiable factors (BMI, smoke and alcohol abuse), non-modifiable factors (gender, age), and medical history characteristics, such as diabetes mellitus (DM), avascular necrosis (AVN) of femoral head, femoral neck fracture, rheumatoid arthritis (RA), cardiovascular disease (CVD), and osteoarthritis (OA) etc. The meta-analysis was applied by using risk ratios with 95% corresponding intervals. Sensitivity analysis and publication bias were performed to further assess the credibility of the results.ResultsOverall, 40 studies with 3,561,446 hips were enrolled in our study. By implementing cumulative meta-analysis, higher BMI was found associated with markedly increased PJI risk after primary THA [2.40 (2.01-2.85)]. Meanwhile, medical characteristics including DM [1.64 (1.25-2.21)], AVN [1.65 (1.07-2.56)], femoral neck fracture [1.75 (1.39-2.20)], RA [1.37 (1.23-1.54)], CVD [1.34 (1.03-1.74)], chronic pulmonary disease (CPD) [1.22 (1.08-1.37)], neurological disease [1.19 (1.05-1.35)], opioid use [1.53 (1.35-1.73)] and iron-deficiency anemia (IDA) [1.15 (1.13-1.17)] were also significantly correlated with higher rate of PJI. Conversely, dysplasia or dislocation [0.65 (0.45-0.93)], and OA [0.70 (0.62-0.79)] were protective factors. Of Note, female gender was protective for PJI only after longer follow-up. Besides, age, smoking, alcohol abuse, previous joint surgery, renal disease, hypertension, cancer, steroid use and liver disease were not closely related with PJI risk.ConclusionOur finding suggested that the individual-related risk factors for PJI after primary THA included high BMI, DM, AVN, femoral neck fracture, RA, CVD, CPD, neurological disease, opioid use and IDA, while protective factors were female gender, dysplasia/ dislocation and OA.

Project description:BackgroundPeriprosthetic fractures are a devastating complication of total hip arthroplasty (THA) and are associated with significantly higher mortality rates in the postoperative period. Given the strain that periprosthetic fractures place on the patient as well as the healthcare system, identifying and optimizing medical comorbidities is essential in reducing complications and improving outcomes.MethodsAll THA with primary indications of osteoarthritis from 2007 to 2020 were queried from the National Surgical Quality Improvement Program database. Demographic data, preoperative laboratory values, medical comorbidities, hospital course, and acute complications were collected and compared between patients with and without readmission for a periprosthetic fracture. A multivariate logistic regression analysis was performed to determine associated independent risk factors for periprosthetic fractures after index THA.ResultsThe analysis included 275,107 patients, of which 2539 patients were readmitted for periprosthetic fractures. Patients with postoperative fractures were more likely to be older (>65 years), females, BMI >40, and increased medical comorbidities. Preoperative hypoalbuminemia, hyponatremia, and abnormal estimated glomerular filtration rates were independent risk factors for sustaining a periprosthetic fracture and readmission within 30 days. Modifiable patient-related factors of concurrent smoking and chronic steroid use at the time of index THA were also independent risk factors for periprosthetic fractures. Inpatient metrics of longer length of stay, operative time, and discharge to rehab predicted postarthroplasty fracture risk. Readmitted fracture patients subsequently had increased risks of developing a surgical site infection, urinary tract infection, and requiring blood transfusions.ConclusionsPatients with hypoalbuminemia, hyponatremia, and abnormal estimated glomerular filtration rate are at increased risk for sustaining periprosthetic fractures after THA. Preoperative optimization with close monitoring of metabolic markers and modifiable risk factors may help not only prevent acute periprosthetic fractures but also associated infection and bleeding risk with fracture readmission.

Project description:To examine the mortality and implant survivorship of proximal femoral replacement (PFR), revision total hip arthroplasty (REV) and open reduction internal fixation (ORIF) in the treatment of acute periprosthetic fractures of the proximal femur, we retrospectively reviewed 97 consecutive acute periprosthetic proximal femoral fractures from 2000 to 2010. Three groups were defined: PFR (n=21), REV (n=19), and ORIF (n=57). Outcome measures were all-cause mortality, implant failure, and reoperation. Competing Risks survival analysis of overall mortality during the mean 35-month follow-up showed no statistical difference between the three groups (P=0.65; 12 and 60 month mortality for PFR: 37%, 45%; REV: 16%, 46%; ORIF: 14%, 100%). Implant survival was worse for the PFR group (P=0.03, 12 and 60-month implant failure rate for PFR: 5%, 39%; REV: 7%, 7%; ORIF 2%, 2%). We conclude that PFR as compared with REV or ORIF may have worse medium-term implant survival, primarily due to instability and dislocation.

Project description:BackgroundPeriprosthetic femur fractures (PPFFs) following total hip arthroplasty (THA) have increased in the past decade as the demand for primary surgery continues to grow. Although there is now more evidence to describe the treatment of Vancouver B fractures, there is still limited knowledge regarding factors that cause surgeons to perform either an open reduction and internal fixation (ORIF) or revision THA (rTHA). The purpose of this study was to determine what type of surgeons treat Vancouver B PPFFs at 11 major academic institutions and if there are trends in treatment decision-making regarding the use of ORIF or rTHA based on surgical training or patient factors.MethodsThis multicenter retrospective study evaluated patients surgically treated for Vancouver B PPFF after THA between 2014 and 2019. Patients from 11 academic centers located in the United States were included in this study. Surgical outcomes and patient demographics were evaluated based on surgeon training, surgical treatment type, and institution.ResultsPresence of Vancouver B2 (odds ratio [OR]: 0.02, P < .001) or B3 (OR: 0.04, P < .001) fractures were independent risk factors for treatment with rTHA. Treatment by a trauma (OR: 12.49, P < .001) or other-specified surgeon (OR: 13.63, P < .001) were independent risk factors for ORIF repair of Vancouver B fractures. There were no differences in outcomes based on surgeon subspecialty training.ConclusionsThis study showed the trends in surgeons who surgically manage Vancouver B fractures at 11 major academic institutions and highlighted that regardless of surgical training or surgical treatment type, postoperative outcomes following management of PPFF were similar.

Project description:IntroductionPrevious evidence has established that early surgery is beneficial to improve outcomes for individuals with native hip fractures in the elderly population. Patients who sustain a periprosthetic fracture have been demonstrated to have similar demographics and outcomes as those with native fractures around the hip and knee. We therefore set out to determine if there is a similar difference in perioperative outcomes between early and delayed surgery for periprosthetic fractures of the hip and knee through a systematic review and meta-analysis.MethodsLiterature search outputs were screened for studies meeting the inclusion criteria. The groups of early surgery and delayed surgery were defined by study authors. The primary outcome measure was 30 day mortality. Where there was sufficient study homogeneity, a random-effects meta-analysis was performed. Individual study risk of bias was assessed using the ROBINS-I criteria, with the GRADE criteria used for independent outcome evaluation. The review protocol was registered on PROSPERO prior to commencement (Registration number CRD42019149360).ResultsThe inclusion criteria was met in 11 studies (n = 3006). Mean time to surgery from admission for reporting studies was 64 h. 59.6% patients underwent early surgery as defined by the study authors. We identified a significantly lower risk of 30 day mortality for those with early surgery versus delayed surgery (RR 0.21; 95% CI 0.05, 0.90; p = 0.04, n = 2022). There were also significantly better outcomes for early versus delayed surgery regarding: medical complications, length of stay, transfusion risk, and reoperation. The quality of evidence for all the individual outcomes was low or very low.ConclusionsThere is evidence that delaying surgery in those with periprosthetic fractures of the hip and knee has a deleterious impact on mortality and other important patient outcomes. There are, however, notable limitations to the existing available literature, with further appropriately designed large-scale studies required to confirm these findings.

Project description:BackgroundDespite an increasing incidence and associated morbidity, the optimal timing for the surgical management of periprosthetic hip fractures remains unknown. This study sought to explore whether time to surgery was associated with medical or surgical complications.MethodsA retrospective review of Medicare data from 2010 to 2014 was performed using PearlDiver. All patients with a periprosthetic hip fracture greater than 90 days from surgery and undergoing open reduction internal fixation (ORIF) or revision total hip arthroplasty (RTHA) were included. Time to surgery was measured from diagnosis and dichotomized at 48 hours.ResultsOf 342 patients undergoing ORIF, 269 (79%) had surgery within 48 hours. Of 255 patients undergoing RTHA, 142 (56%) had surgery within 48 hours. For ORIF, surgery more than 48 hours after diagnosis was associated with an increased rate of 30-day deep vein thrombosis or pulmonary embolism (15% vs 7%, P = .03), which remained after adjustment (odds ratio [OR]: 2.71, 95% confidence interval [CI]: 1.11-6.45). A similar association was seen for RTHA (12% vs 6%, P = .09 and OR: 2.61, 95% CI 1.01-7.24). For RTHA, surgery more than 48 hours after diagnosis was associated with an increased rate of 90-day periprosthetic joint infection (12% vs 4%, P = .007), which remained after adjustment (OR: 3.86, 95% CI: 1.36-12.72). A similar but not significant association was seen for ORIF (7% vs 3%, P = .18 and OR: 2.65, 95% CI: 0.73-8.91).ConclusionsAmong Medicare patients with a periprosthetic hip fracture, time to surgery greater than 48 hours was associated with increased medical and surgical complications.

Project description:PurposeThe purpose of this hospital-based case-control study was to evaluate the risk factors for periprosthetic joint infection (PJI) of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Chinese patients.MethodFrom January 2000 to December 2012, 45 patients undergoing THA and TKA who developed PJI were recruited for case subjects; controls were 252 without PJI, matched by year of index for surgery and type of surgery. Conditional logistic regressions were run to compute odds ratios (ORs) and 95% confidence intervals (CIs).ResultsDemographic factors and comorbid conditions associated with an increased adjusted risk of PJI (in decreasing order of significance) were diabetes (OR?=?5.47, 95% CI: 1.77-16.97; p?=?0.003), age (65-75 vs. 45-65 years) (OR?=?3.36, 95% CI: 1.30-8.69; p?=?0.013), BMI (?28 vs. 18.5-28 kg/m2) (OR?=?2.77, 95% CI: 1.20-6.40; p?=?0.017), place of residence (rural) (OR?=?2.63, 95% CI: 1.13-6.10; p?=?0.025) and alcohol abuse (OR?=?2.95, 95% CI: 1.06-8.23; p?=?0.039).ConclusionPatients with diabetes, older age, BMI of ?28 kg/m2 and alcohol abuse or living in rural areas, had increased PJI risk. Additional systematic large-scale studies are needed to verify these results.

Project description:Periprosthetic femoral hip fractures are subject to an increasing incidence and are often considered to be related to osteoporosis. However, there are no available studies that have determined the frequency of osteoporosis in affected patients using gold standard dual-energy X-ray absorptiometry (DXA). In this retrospective comparative study, we analyzed the DXA results of 40 patients with periprosthetic femoral hip fractures who were treated surgically in our department. DXA measurements were performed at the total hip and the lumbar spine to determine bone mineral density T-scores. Data were compared to two age-, sex-, and BMI-matched control groups in which patients underwent DXA prior to aseptic revision surgery for other causes or primary THA (consisting of 40 patients each). The mean T-score in the periprosthetic fracture cohort was significantly lower (- 1.78 ± 1.78) than that of the aseptic revision (- 0.65 ± 1.58, mean difference - 1.13 [95% CI - 1.88 to - 0.37]; p = 0.001) and the primary THA cohort (- 0.77 ± 1.34, mean difference - 1.01 [95% CI - 1.77 to - 0.26]; p = 0.005). Accordingly, osteoporosis was detected more frequently (45%) in the fracture cohort compared to patients undergoing aseptic revision (12.5%) and primary THA (10%). In conclusion, almost half of the patients with periprosthetic femoral hip fractures have osteoporosis according to DXA measurements. A regular assessment of bone health in THA enables identification of patients with osteoporosis who likely benefit from initiation of osteoporosis medication and cemented stem fixation.

Project description:BackgroundPrimary care hospitals and regional trauma centers play an essential role in the treatment of hip fractures.ObjectiveThis study investigated the relationship between patient-related parameters and in-hospital mortality as well as complications of hip fractures at a regional trauma center.MethodsIn a retrospective study, data were collected from all patients > 60 years admitted over 2 years to a regional trauma center with a hip fracture. Patient-related parameters included age, sex, fracture location, method of surgical treatment, time of surgery, duration of surgery, length of inpatient stay, blood transfusion, complications, comorbidities, use of anticoagulant medication and need for postoperative intensive care treatment. The relationship between these parameters and hospital mortality as well as complications was investigated.ResultsData were collected from 360 patients undergoing 335 surgeries (f:m 225:110) with a mean age of 83 ± 8 years. The total in-hospital mortality rate was 7.76% (n = 26). Factors increasing in-hospital mortality included: age > 85 years (odds ratio [OR] 5.126; 95% confidence interval [CI] 0.665-39.498; p = 0.1167); male sex (OR 1.85 95%-CI [0.82-4.14]; p = 0.0555); time of surgery > 24 h (OR 1.896 95%-CI [0.661-5.441]; p = 0.2341); ≥ 3 comorbidities (OR 10.61 95%-CI [3.681-27.501]; p < 0.0001); intake of anticoagulants (OR 6.19 95%-CI [2.69-14.24]; p < 0.0001) and postoperative intensive care (OR 5.9 95%-CI [2.56-13.76]; p < 0.0001).ConclusionIn the present study a statistically significant influence of the number of comorbidities or Charlson comorbidity index, the intake of anticoagulant drugs and need for postoperative intensive care treatment on the in-hospital mortality of patients with proximal femoral fractures in a regional trauma center was found.
