ABSTRACT

BACKGROUND: The surgical approach used for arthroplasty in the setting of hip fracture has traditionally been decided based on surgeon preference. This study analyzed the ef-fect of the surgical approach on hospital quality measures, complications, and mortality in patients treated with hip arthroplasty for fracture fixation. METHODS: A cohort of consecutive acute hip fracture pa-tients who were 60 years of age or older and who underwent hemiarthroplasty (HA) or total hip arthroplasty (THA) at one academic medical center between January 2014 and January 2018 was included. Patient demographics, length of stay (LOS), surgery details, complications, ambulation at dis-charge, discharge location, readmission, and mortality were recorded. Two cohorts were included based on the surgical approach: the anterior-based cohort included the direct an-terior and anterolateral approaches and the posterior-based cohort included direct lateral and posterior approaches. RESULTS: Two hundred five patients were included: 146 underwent HA (81 anterior-based and 65 posterior-based) and 79 underwent THA (37 anterior-based and 42 posterior-based). The mean age of the HA and THA cohorts was 84.1 ± 7.5 and 73.7 ± 8.0 years, respectively. There was no dif-ference in LOS, time to surgery, or surgical time between the two cohorts for HA and THA. There were no differences in perioperative complications, including dislocation, ob-served based on surgical approach. No difference was found between readmission rates and mortality. CONCLUSION: In this cohort of hip fracture arthroplasty patients, there was no difference observed in hospital quality measures, readmission, or mortality in patients based on sur-gical approach. These results are in contrast with literature in elective arthroplasty patients supporting the use of an anterior approach for potential improved short-term outcomes.

ABSTRACT

AIMS: The aim of this study was to assess the association of mortality and reoperation when comparing cemented and uncemented hemiarthroplasty (HA) in hip fracture patients aged over 65 years. METHODS: This was a population-based cohort study on hip fracture patients using prospectively gathered data from several national registries in Denmark from 2004 to 2015 with up to five years follow-up. The primary outcome was mortality and the secondary outcome was reoperation. Hazard ratios (HRs) for mortality and subdistributional hazard ratios (sHRs) for reoperations are shown with 95% confidence intervals (CIs). RESULTS: A total of 17,671 patients with primary HA were identified (9,484 uncemented and 8,187 cemented HAs). Compared to uncemented HA, surgery with cemented HA was associated with an absolute risk difference of 0.4% for mortality within the period zero to one day after surgery and an adjusted HR of 1.70 (95% CI 1.22 to 2.38). After seven days, there was no longer any association, with an adjusted HR of 1.07 (95% CI 0.90 to 1.28). This continued until five years after surgery with a HR of 1.01 (95% CI 0.96 to 1.06). There was a higher proportion of reoperations due to any reason after five years in the uncemented group with 10.2% compared to the cemented group with 6.1%. This yielded an adjusted sHR of 0.65 (95% CI 0.57 to 0.75) and difference continued up until five years after the surgery, demonstrating a sHR of 0.70 (95% CI 0.59 to 0.83). CONCLUSION: In a non-selected cohort of hip fracture patients, surgery with cemented HA was associated with a higher relative mortality during the first postoperative day compared to surgery with uncemented HA, but there was no difference after seven days up until five years after. In contrast, surgery with cemented HA was associated with lower risk of reoperation up to five years postoperatively compared with surgery with uncemented HA. There was a higher relative mortality on the first postoperative day for cemented HA versus uncemented HA. There was no difference in mortality after seven days up until five years after surgery. There were 6.1% reoperations for cemented HA compared to 10.2% for uncemented HA after five years. Cite this article: Bone Joint J 2022;104-B(1):127-133.

ABSTRACT

ABSTRACT: The effect of hypothermia as a mortality risk factor at 30 days in the elderly who had hip fracture (HF) surgery is still controversial because it may be due to a set of poorly identified factors. In this study, we aim to determine if exposure to intra and immediate postoperative hypothermia increases the incidence of mortality at 30 days in elderly patients who had HF surgery.Survival study in the elderly who had HF surgery with and without exposure to hypothermia. Sociodemographic, anesthetic and surgical factors were collected. The temperature of the rectum was measured at the end of the surgery and in the recovery room. The effect of hypothermia was analyzed by the incidence of mortality at 30 days. Other results were considered, such as, surgical site infection (SSI), blood transfusions, and influence of implants used in the 30-day mortality.Three hundred eighty five subjects were eligible, to include 300. Inadvertent hypothermia was 12%, the 30-day overall mortality was 9% and in subjects with hypothermia it was 25% (P = .002). Subjects with hypothermia had a higher risk of SSI (relative risk 4.2, 95% confidence interval 1.3-13.6, P = .03) and receive more transfusions (relative risk 3.6, 95% confidence interval 2.0-6.5, P < .001).Elderly subjects with HF exposed to hypothermia who undergo hip hemiarthroplasty and who receive 2 or more blood transfusions during their treatment, are at greater risk of dying after 30 days of the surgery. Hypothermia, as a possible causative factor of mortality, should continue to be studied.

ABSTRACT

OBJECTIVE: Cemented hemiarthroplasty is recommended for the vulnerable hip fracture population because of beneficial long-term outcomes. However, the association between cemented hemiarthroplasty and short-term mortality is controversial. To increase a preparedness of potential complication after cemented hemiarthroplasty, we aimed to evaluate the trajectory of the effect of cemented hemiarthroplasty on short-term in-hospital outcomes. METHODS: We investigated in-hospital mortality and complications between cemented hemiarthroplasty and cementless hemiarthroplasty using a nationwide multicenter database from 2010 to 2016 with a propensity-score matching analysis. We analyzed in-hospital mortality from 1 to 14 days after surgery. We also investigated in-hospital complications that may associate with mortality. RESULTS: After matching of 31,322 cases, we found no significant difference in 30-day in-hospital mortality between the cemented and cementless hemiarthroplasty groups (hazard ratio, HR [95% confidence interval, CI], 1.2 [0.89-1.6], p = 0.23). However, the 1- to 10-day postoperative mortality rates were significantly higher in the cemented group and the association becomes weaker as the postoperative period increased (day 1; HR [95% CI]: 3.5 [1.6-7.68]; day 10; HR [95% CI]: 1.59 [1.07-2.37]). The incidence of stroke and intensive care unit (ICU) admission was also significantly higher in the cemented group. CONCLUSION: Cemented hemiarthroplasty was not significantly associated with an increase in overall in-hospital mortality but was significantly associated with short-term mortality from 1-day to 10-day after surgery. The incidence of stroke and ICU admission was also significantly higher in the cemented group. Surgeons should pay more attention to the risk of mortality and stroke in patients undergoing cemented hemiarthroplasty, especially in the early days of hospitalization.

ABSTRACT

BACKGROUND: We performed an updated systematic review and meta-analysis which enrolled 25 prospective randomized controlled trials (RCTs) to compare the outcomes between total hip arthroplasty (THA) and hemiarthroplasty (HA) in patients with femoral neck fractures (FNFs). METHODS: We searched English databases which included PubMed, Embase (vis OvidSP), The Cochrane Library, and Web of Science, and Chinese databases Chinese National Knowledge Infrastructure (CNKI), VIP, Wang Fang, and China Biology Medicine Disc (CBM) in July 2020. The quality of each study was assessed according to the Cochrane Collaboration's Risk of Bias. Risk ratios (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were pooled with random-effects models. Data regarding baseline characteristics, hospital and surgery outcomes, clinical outcomes, patients' quality of life, common complications, prothesis-related complications, mortality, and costs were reported. RESULTS: A total of 25 RCTs involving 3223 patients (1568 THA and 1655 HA) were included. THA had longer hospital length (WMD = 0.721, P < 0.0001) and surgery time (WMD = 20.044, P < 0.0001), and more blood loss compared with HA (WMD = 69.109, P < 0.0001). THA showed better ratings in the Harris Hip Score during follow-up periods between 1 and 5 years while no differences within 6 months and after 9 years. THA was associated with higher quality-of-life EuroQol-5 Dimension (EQ-5D) scores after 2 years of surgery but no difference within 1 year. There was no difference in common complications. THA had significant higher rate of dislocation (WMD = 1.897, P = 0.002) and lower acetabular erosion (WMD = 0.030, P = 0.001). For mortality, there was no difference during all the follow-up periods except for slightly higher 2-year mortality after surgery. CONCLUSION: This meta-analysis demonstrates that THA has better medium-term functional results and quality of life and lower acetabular erosion rate, while HA shows better in reducing hospital stay, surgery time, and blood loss and also has lower dislocation rate.

ABSTRACT

AIMS: To evaluate the rate of dislocation following dual mobility total hip arthroplasty (DM-THA) in patients with displaced femoral neck fractures, and to compare rates of dislocation, surgical-site infection, reoperation, and one-year mortality between DM-THA and bipolar hemiarthroplasty (BHA). METHODS: Studies were selected based on the following criteria: 1) study design (retrospective cohort studies, prospective cohort studies, retrospective comparative studies, prospective comparative studies, and randomized controlled studies (RCTs)); 2) study population (patients with femoral neck fracture); 3) intervention (DM-THA or BHA); and 4) outcomes (complications during postoperative follow-up and clinical results). Pooled meta-analysis was carried out to evaluate the dislocation rate after DM-THA and to compare outcomes between DM-THA and BHA. RESULTS: A total of 17 studies (ten cohort studies on DM-THA and seven comparative studies of DM-THA and BHA) were selected. These studies included 2,793 patients (2,799 hips), made up of 2,263 DM-THA patients (2,269 hips) and 530 BHA patients (530 hips). In all, 16 studies were analyzed to evaluate dislocation rate after DM-THA. The cumulative dislocation rate was 4% (95% confidence interval (CI) 3 to 5). Seven studies were analyzed to compare the rates dislocation and surgical-site infection. The rate of dislocation was significantly lower in the DM-THA group than in the BHA group (risk ratio (RR) 0.3; 95% CI 0.17 to 0.53, p < 0.001, Z -4.11). There was no significant difference in the rate of surgical-site infection between the two groups (p = 0.580). Six studies reported all-cause reoperations. The rate of reoperation was significantly lower in the DM-THA group than in the BHA group (RR 0.5; 95% CI 0.32 to 0.78, p = 0.003, Z -3.01). Five studies reported one-year mortality. The mortality rate was significantly lower in the DM-THA group than in the BHA group (RR 0.58 95% CI 0.45 to 0.75, p < 0.0001, Z -4.2). CONCLUSION: While the evidence available consisted mainly of non-randomized studies, DM-THA appeared to be a viable option for patients with displaced fractures of the femoral neck, with better reported rates of dislocation, reoperation, and mortality than BHA.

ABSTRACT

A retrospective study of Staphylococcus aureus isolates from orthopaedic patients treated between 2000 and 2017 at Akershus University Hospital, Norway was performed using a genome-wide association approach. The aim was to characterize and investigate molecular characteristics unique to S. aureus isolates from HHA associated prosthetic joint infections and potentially explain the HHA patients' elevated 1-year mortality compared to a non-HHA group. The comparison group consisted of patients with non-HHA lower-extremity implant-related S. aureus infections. S. aureus isolates from diagnostic patient samples were whole-genome sequenced. Univariate and multivariate analyses were performed to detect group-associated genetic signatures. A total of 62 HHA patients and 73 non-HHA patients were included. Median age (81 years vs. 74 years; p < 0.001) and 1-year mortality (44% vs. 15%, p < 0.001) were higher in the HHA group. A total of 20 clonal clusters (CCs) were identified; 75% of the isolates consisted of CC45, CC30, CC5, CC15, and CC1. Analyses of core and accessory genome content, including virulence, resistance genes, and k-mer analysis revealed few group-associated variants, none of which could explain the elevated 1-year mortality in HHA patients. Our findings support the premise that all S. aureus can cause invasive infections given the opportunity.

ABSTRACT

BACKGROUND: This meta-analysis was performed to incorporate newly published, high-quality randomized controlled trials (RCTs) to determine the effects of cemented versus uncemented hemiarthroplasty for elderly patients with displaced fracture of the femoral neck. METHODS: The following electronic databases were extensively searched from the inception of the database through December 2018: EMBASE, Medline, the Cochrane Library, and Web of Science. RCTs focusing on the outcomes of cemented and uncemented hemiarthroplasty were reviewed and screened for eligibility. We used the Cochrane Collaboration's Review Manager Software to perform meta-analyses. Two independent reviewers extracted the data and assessed the study quality and bias risk through the Cochrane Collaboration tool. Use fixed effect model or random effect model to pooled data. Cochran's Q statistic was used to evaluate heterogeneity, and I statistic was used to quantify heterogeneity. RESULTS: Fifteen RCTs were enrolled (n = 3790) (uncemented hemiarthroplasty group = 1015; cemented hemiarthroplasty group = 1037) (mean age ranged from 70-85.3 years; all patients > 65 years). The meta-analysis showed that cemented hemiarthroplasty has a longer operating time (weighted mean difference, 8.03; 95% confidence interval (CI) 4.83-11.23; P < .00001), less pain (odds ratio, 0.48; 95% CI 4.83-11.23; P = .02), lower mortality 1-year (odds ratio, 0.78; 95% CI 0.62-0.98; P = .03) and fewer implant-related complications (odds ratio, 0.20; 95% CI 0.13-0.30; P < .00001) than Uncemented hemiarthroplasty. However, there are still some limitations in our study, such as the uniformity of the surgery administration programme and rehabilitation scheme, and the small sample size of the included studies. CONCLUSIONS: Cemented hemiarthroplasty for elderly patients with displaced fracture of femoral neck may acquire better functional results.

ABSTRACT

This study aimed to compare the early outcome of proximal femoral nail antirotation (PFNA) and bipolar hemiarthroplasty (BPH) in elderly intertrochanteric fractures (ITFs) patients aged 85 years or more.This is a prospective cohort study, and we analyzed 120 elderly patients aged 85 years or more presented with ITFs who underwent BPH and PFNA between January 2017 and July 2018. 84 patients treated with PFNA were set as Group A, and 36 patients treated with BPH were set as Group B. Data such as gender, age, period of follow-up, fracture classification (according to Evans-Jensen classification), preoperative ASA (American Society of Anesthesiologists) physical status, interval between injury and operation, method of anaesthesia, duration of operation time, blood loss during surgery, time of weight bearing after operation, incidence of complications 2 weeks after operation, mortality rates and Harris Hip Score 12 months after operation were recorded and compared.There are no statistically significant differences when compared general data in patients from group A and B (P > .05). Operation time in Group A is less than Group B (103.33, 40-230 min vs 122.64, 75-180 minute, P < .01). Blood loss during surgery in Group A is less than Group B (70.24, 50-100 mL vs 194.44, 100-500 mL, P < .01). Time of weight bearing after operation in Group A is longer than Group B (50.70, 7-100 days vs 6.67, 4-14 days, P < .01). Incidence of complications 2 weeks after operation in Group A is less than Group B (14.12% vs 36.11%, P < .01). Mortality rates 12 months after operation in Group A is similar with Group B (13.10% vs 19.44%, P > .05). Harris Hip Score 12 months after operation in Group A is similar with Group B (64.64,0-91 points vs 64.41, 0-90 points, P > .05).Although BPH and PFNA have similar functional outcome and mortality rates 12 months after operation, BPH has more postoperative complications in elderly patients aged 85 years or more with ITFs, Bipolar Hemiarthroplasty should not be selected as the primary option for ITFs in elderly patients aged 85 years or more.

ABSTRACT

The incidence of displaced femoral neck fractures among elderly patients is increasing as the population ages.Historically, the preferred treatment for displaced femoral neck fractures in elderly patients has been hemiarthroplasty with use of cemented fixation of the implant. However, there is evidence that this technique may be associated with fat embolization and subsequent cardiopulmonary arrest in the early postoperative period. Cementing techniques are also associated with increased operative time when compared with cementless techniques.There is increasing evidence that, among elderly patients, the use of uncemented hemiarthroplasty has equivalent functional outcomes and overall mortality rates when compared with the use of hemiarthroplasty with cemented fixation. The main complication associated with uncemented hemiarthroplasty is intraoperative periprosthetic fracture.

ABSTRACT

BACKGROUND: This study aimed to evaluate the effects on mortality of implant selection used and time to surgery in patients aged over 65 years operated for hip fractures. METHODS: A total of 301 patients aged over 65 years were investigated in this study. Patients were divided into three groups as follows: Group 1 cemented hemiarthroplasty (CH), Group 2 cementless hemiarthroplasty (CLH), and Group 3 proximal femoral nail (PFN). Time of surgery, fracture and demographic information were retrospectively recorded. RESULTS: After removing 59 patients with missing information, this study included 242 patients. Mean age of patients was 80.5 years. When patient groups were examined according to treatment method, Group 1 (n=146) comprised 60.3%, Group 2 (n=54) comprised 22.3% and Group 3 (n=42) comprised 17.4% of the study group. There was no significant difference in survival between the patients operated in the first 48 hours and the patients operated later (p=0.834). There was an effect on the survival of treatment implant selection (p=0.016). Patients with CH were observed to survive longer than patients with CLH and PFN. CONCLUSION: Operation in the first 48 hours was not observed to affect mortality. Additionally, while sex and age were found to be effective on mortality, implant selection was also concluded to affect mortality.

ABSTRACT

OBJECTIVE: To evaluate the safety and effectiveness of conservative treatment (CST), internal fixation (IF), and hemiarthroplasty (HA) in treating patients older than 75 years with impacted femoral neck fracture (IFNF). DESIGN: A randomized clinical trial to compare clinical outcomes of CST, IF, and HA in IFNF patients older than 75 years with a 1:1:1 ratio. SETTING: Nanjing First Hospital, Nanjing Medical University, Nanjing, China. PARTICIPANTS: A total of 154 patients with IFNF aged between 75 and 97 years. INTERVENTION: Patients with IFNF were allocated to CST, IF, and HA. They all received a 36-month follow-up. MEASUREMENTS: All patients were evaluated by Harris hip score (HHS) (primary outcome) for hip function, European Quality of Life-5 Dimensions (EQ-5D) index scores for health-related quality of life, and visual analogue scale score for hip pain. Operation duration, blood loss, mortality, union rate, complications, and reoperation were also recorded. Assessors were blind to the type of treatment. RESULTS: The baseline parameters of the three groups were similar. IF group had much lower blood loss than HA group (P < .05), while no significant difference in operative duration was found between the two groups (P > .05). HHS in HA group was significantly higher at 1, 3, and 6 months (P < .05), but no significant difference in HHS was found between CST and IF groups at any of the time points during the overall follow-up (P > .05). EQ-5D index score was higher in HA group at each follow-up within 1 year (P < .05), but the difference was not significant at 2- and 3-year follow-up (P > .05). There was no significant difference in mortality among the three groups at each follow-up point (P > .05). The nonunion rate was 11.76% (6/51) in CST group and 9.80% (5/51) in IF group and showed no significant difference (P > .05). CONCLUSION: CST may be a feasible way for IFNF in the older patients.

ABSTRACT

Background and purpose - Femoral neck fractures are commonly treated with cemented or uncemented hemiarthroplasties (HA). We evaluated differences in mortality and revision rates in this fragile patient group.Patients and methods - From January 1, 2007 until December 31, 2016, 22,356 HA procedures from the Dutch Arthroplasty Register (LROI) were included. For each HA, follow-up until death, revision, or end of follow-up (December 31, 2016) was determined. The crude revision rate was determined by competing risk analysis. Multivariable Cox regression analyses were performed to evaluate the effect of fixation method (cemented vs. uncemented) on death or revision. Age, sex, BMI, Orthopaedic Data Evaluation Panel (ODEP) rating, ASA grade, surgical approach, and previous surgery were included as potential confounders.Results - 1-year mortality rates did not differ between cemented and uncemented HA. 9-year mortality rates were 53% (95% CI 52-54) in cemented HA compared to 56% (CI 54-58) in uncemented HA. Multivariable Cox regression analysis showed similar mortality between cemented and uncemented HA (HR 1.0, CI 0.96-1.1). A statistically significantly lower 9-year revision rate of 3.1% (CI 2.7-3.6) in cemented HA compared with 5.1% (CI 4.2-6.2) in the uncemented HA was found with a lower hazard ratio for revision in cemented compared with uncemented HA (HR 0.56, CI 0.47-0.67).Interpretation - Long-term mortality rates did not differ between patients with a cemented or uncemented HA after an acute femoral neck fracture.

ABSTRACT

Background and purpose - The bone cement implantation syndrome characterized by hypotension and/or hypoxia is a well-known complication in cemented arthroplasty. We studied the incidence of hypotension and/or hypoxia in patients undergoing cemented or uncemented hemiarthroplasty for femoral neck fractures and evaluated whether bone cement was an independent risk factor for postoperative mortality.Patients and methods - In this retrospective cohort study, 1,095 patients from 2 hospitals undergoing hemiarthroplasty with (n = 986) and without (n = 109) bone cementation were included. Pre-, intra-, and postoperative data were obtained from electronic medical records. Each patient was classified for grade of hypotension and hypoxia during and after prosthesis insertion according to Donaldson's criteria (Grade 1, 2, 3). After adjustments for confounders, the hazard ratio (HR) for the use of bone cement on 1-year mortality was assessed.Results - The incidence of hypoxia and/or hypotension was higher in the cemented (28%) compared with the uncemented group (17%) (p = 0.003). The incidence of severe hypotension/hypoxia (grade 2 or 3) was 6.9% in the cemented, but not observed in the uncemented group. The use of bone cement was an independent risk factor for 1-year mortality (HR 1.9, 95% CI 1.3-2.7), when adjusted for confounders.Interpretation - The use of bone cement in hemiarthroplasty for femoral neck fractures increases the incidence of intraoperative hypoxia and/or hypotension and is an independent risk factor for postoperative 1-year mortality. Efforts should be made to identify patients at risk for BCIS and alternative strategies for the management of these patients should be considered.

ABSTRACT

AIM: To compare the efficacy and safety of cemented and uncemented hemiarthroplasty in elderly patients with femoral neck fracture. MATERIALS AND METHODS: We searched PubMed, EMBASE, and Cochrane Library databases for published randomized clinical trials comparing cemented hemiarthroplasty with uncemented hemiarthroplasty in elderly patients with a femoral neck fracture. The search was not limited to language, time, or other factors. The quality of each study was assessed using the revised Jadad scale. Two researchers independently extracted data from all selected studies, including the following base line data: study period, fracture stage, number of patients, male female ratio, average age, and per-protocol (PP) or intent-to-treat (ITT), and the interest outcomes: the mortality at 12 months, operative time, hospital stay, common complications, prosthetic-related complications, blood loss and Harris Hip Score (HHS). Fixed-effects or random-effects models with mean differences and odds ratios were used to pool the continuous and dichotomous variables to determine heterogeneity of the included studies. RESULTS: A total of 8 studies involving 1577 hips (782 uncemented and 795 cemented) were included in this meta-analysis. The meta-analysis is indicated that the operation time of cemented hemiarthroplasty was longer than uncemented hemiarthroplasty and there was statistical significance between two groups (OR = -7.30, 95%CI, -13.13, -1.46; P = .01). However, there was no significant difference between the two methods of fixation in mortality at 12 months (OR = 1.22, 95%CI, 0.94-1.59; P = .14), hospital stay (OR = 0.26, 95%CI, -0.41, 0.93; P = .44), blood loss (OR = -17.94, 95%CI, -65.83, 29.95; P = .46), and HHS score. There were significant differences in the common complications of pulmonary embolism between the two groups, but there were no differences in the other five common complications. The results showed that uncemented hemiarthroplasty could reduce the incidence of pulmonary embolism after operation. Moreover, the outcomes of prosthetic-related complications showed that there were significant differences between the two groups in periprosthetic fracture (OR = 8.32, 95%CI, 3.85-17.98; P < .00001) and prosthetic subsidence and loosening (OR = 5.33, 95%CI, 2.18-13.00; P = .0002). CONCLUSIONS: Our study shows that uncemented prosthesis can shorten the operation time and reduce the incidence of pulmonary embolism, but it does not reduce mortality, blood loss, and hospital stay. Most importantly, the incidence of prosthetic-related complications was higher in uncemented patients.

ABSTRACT

INTRODUCTION: The treatment of unstable intertrochanteric fracture in elderly patients is challenging and how to treat these patients remains controversial. The purposes of this study were to compare (1) reoperation rate, (2) mortality and (3) the postoperative change of walking ability between patients undergoing internal fixation (IF) and those undergoing bipolar hemiarthroplasty (HA) due to this type of fracture based on the data from the Korean Hip Fracture Registry. MATERIALS AND METHODS: Between July 2014 and June 2016, we extracted 623 unstable intertrochanteric fractures (616 patients aged ≥ 65 years) according to the classification of the Association for the Study of Internal Fixation-American Orthopaedic Trauma Association. Among the 564 patients, 396 were treated with IF (IF group) and 168 with bipolar HA (HA group). We compared the reoperation rate and mortality between IF group and HA group. In patients, who were followed up more than 2 years after the surgery, we compared the postoperative change of walking activity from ambulatory outdoors (Koval's grade 1, 2, 3) to housebound (Koval's grade 4, 5, 6). RESULTS: The rate of reoperation was higher in the IF group (24/396, 6.1%) than in the HA (4/168, 2.4%) (p = 0.046). At the final follow-up, 79 (35.7%) of the 221 IF patients became housebound, whereas 21 (23.3%) of the 90 HA patients became housebound (p = 0.022). CONCLUSION: This study showed HA was associated with lower rate of reoperation and lower decrement rate of walking ability compared to IF in elderly patients with unstable intertrochanteric fractures.

ABSTRACT

Background and purpose - Surgical site infection (SSI) is a devastating complication of hip fracture surgery. We studied the contribution of early deep SSI to mortality after hip fracture surgery and the risk factors for deep SSI with emphasis on the duration of surgery.Patients and methods - 1,709 patients (884 hemi-arthroplasties, 825 sliding hip screws), operated from 2012 to 2015 at a single center were included. Data were obtained from the Norwegian Hip Fracture Register, the electronic hospital records, the Norwegian Surveillance System for Antibiotic Use and Hospital-Acquired Infections, and the Central Population Register.Results - The rate of early (≤ 30 days) deep SSI was 2.2% (38/1,709). Additionally, for hemiarthroplasties 7 delayed (> 30 days, ≤ 1 year) deep SSIs were reported. In patients with early deep SSI 90-day mortality tripled (42% vs. 14%, p < 0.001) and 1-year mortality doubled (55% vs. 24%, p < 0.001). In multivariable analysis, early deep SSI was an independent risk factor for mortality (RR 2.4 for 90-day mortality, 1.8 for 1-year mortality, p < 0.001). In univariable analysis, significant risk factors for early and delayed deep SSI were cognitive impairment, an intraoperative complication, and increasing duration of surgery. However, in the multivariable analysis, duration of surgery was no longer a significant risk factor.Interpretation - Early deep SSI is an independent risk factor for 90-day and 1-year mortality after hip fracture surgery. After controlling for observed confounding, the association between duration of surgery and early and delayed deep SSI was not statistically significant.

ABSTRACT

BACKGROUND/OBJECTIVE: The purpose of this study is to analyze the effect of surgical methods on mortality and the relative risk of patients who underwent internal fixation (IF) or hemiarthroplasty (HA) after being diagnosed as a pertrochanteric fracture over 65 years old in a Korean nationwide cohort with a single insurance medical system. METHODS: The Korean National Health Insurance Service-Senior cohort (NHIS-Senior, NHIS-2018-2-111) was used in this study. The eligibility criteria for incident hip fracture patients were the following: (1) first-time admission to acute care hospitals (index admission) with pertrochanteric fracture (ICD-10 S721), (2) three years of hip fracture-free period, (3) recipients of typical surgeries including IF, HA, (4) age between 65 and 99. RESULTS: a total of 7223 patients were enrolled in the cohort. There were 1662 patients (23%) in the HA group and 5561 patients (77%) in the IF group. Mortality rates of the IF group and HA group were 13.46 and 17.94 cases per 100 person-years, respectively. In the multivariable-adjusted Cox proportional hazard model, the HA group had 1.22 times more hazard of all-cause mortality than IF group (aHR 1.22, 95% CI 1.13-1.32). In subgroup analysis, aged 65-79 and female patients showed a prominent association between surgery type and mortality (aHR 1.52, 95% CI 1.29-1.79). CONCLUSIONS: In patients with pertrochanter fracture over 65 years, 1.22-fold mortality rate was observed when HA was performed compared to that of IF, and the difference in mortality was particularly prominent within 1-year after surgery.

ABSTRACT

INTRODUCTION: Unstable intertrochanteric femoral fractures in the elderly require either fixation or joint sacrificing surgery; proximal femoral nail (PFN) and bipolar hemiarthroplasties (BPH) are the most common interventions. PFN is considered to be the ideal construct for these fractures; however, the usage of hemiarthroplasties to facilitate earlier mobilization has been on a rise. Currently there is no consensus on the superiority of one of these two techniques over the other and the present review was done to determine this. RESEARCH QUESTION: Is PFN a better alternative to BPH for unstable intertrochanteric femur fractures in the elderly? OBJECTIVE: The present systematic review and meta-analysis was conducted to determine the superiority of PFN over BPH by comparing the primary outcomes like mortality, Harris Hip scores (HHS), complications, and re-operations. Additionally, secondary outcomes like blood loss, duration of surgery, and period of hospital stays were also compared. METHODOLOGY: Three databases of PubMed, EMBASE, and SCOPUS were searched for relevant articles that directly compared PFN and BPH in unstable intertrochanteric femur fractures in the elderly. RESULTS: We analyzed a total of seven studies published between the years 2005 to 2017. There were four retrospective and three prospective randomized controlled studies. The number of patients in these studies ranged from 53 to 303. PRIMARY OUTCOMES: There was a significant difference in HHS between two groups with standard mean difference of - 0.51 (range - 0.67 to -0.36), favouring the PFN group. The rate of mortality was higher in the BPH group with odds ratio of 2.07 (range 1.40-3.08). Implant-related complications like fractures and subsidence were more in BPH group but this was not significant. SECONDARY OUTCOMES: Mean surgical time (standard mean difference 2.19) and blood loss (3.75) were significantly less in the PFN group. The duration of hospital stay was also found to be significantly less in the PFN group (2.66). CONCLUSION: Proximal femoral nails are superior to bipolar hemiarthroplasties for unstable intertrochanteric femoral fractures in the elderly. PFN imparts better functional outcomes and has lower rates of overall mortality. Additionally it is faster surgery, with lesser blood loss contributing to better results.
