Wintertime surgery increases the risk of conversion to hip arthroplasty after internal fixation of femoral neck fracture

Comparative analysis of the quality of life regarding patients who underwent hip replacement in public versus private hospitals in Hungary

The study aimed to investigate the impact of hip replacement surgery on the quality of life and to compare the outcomes by sociodemographic and surgical data in Hungarian public and private hospitals. Patients were selected at the Department of Orthopaedics (Clinical Centre, University of Pécs) and at the Da Vinci Private Clinic in Pécs. Patients completed the SF-36 and Oxford Hip Score (OHS) questionnaires before the surgery, 6 weeks and 3 months later. We also evaluated socio-demographic data, disease and surgical conditions. The research involved 128 patients, 60 patients in public, 68 patients in private hospital. Despite the different sociodemographic characteristics and surgical outcomes of public and private healthcare patients, both groups had significantly improved the quality of life 3 months after hip replacement surgery measured by OHS and SF-36 physical health scores (p < 0.001). In the mental health score, only the patients of the private health sector showed a significant improvement (p < 0.001). The extent of improvement did not differ between the two healthcare sectors according to the OHS questionnaire (p = 0.985). While the SF-36 physical health score showed a higher improvement for public patients (p = 0.027), the mental health score showed a higher improvement for private patients (p = 0.015).

Reoperation Rate of Internal Fixation for Femoral Neck Fractures in the Elderly - A Retrospective Follow-Up Study in 116 Patients With an Exploration of Risk Factors

Aim

Internal fixation of femoral neck fractures is a widely used procedure that is comparatively less invasive and faster than hip replacement. While head preserving internal fixation of these fractures are still preferred where feasible, a faster recovery and lower reoperation rates make arthroplasty increasingly more appealing, in spite of being a more invasive option. Our aim was to determine the reoperation rate after internal fixation at our institution and to explore relevant risk factors in a geriatric population.

Methods

This monocentric follow-up study was conducted analyzing 116 patients aged 65 and older with femoral neck fractures who were surgically treated with either cancellous screws or dynamic hip screws between 2010 and 2017. We retrospectively collected longitudinal data from our patient database, supplemented by a telephone survey, with a follow-up period of at least 18 months.

Results

Twenty reoperations, due to either a failure of fixation, avascular necrosis, or posttraumatic osteoarthritis, were identified in our cohort, which constituted a reoperation rate of 17.2% (20/116). Fracture displacement was significantly associated with the reoperation risk (HR 8, CI 3-20; P < .001). The reoperation rate was 52.2% in displaced fractures vs 8.9% in undisplaced fractures. No link was found between the reoperation rate and gender, age, BMI, ASA score, type of implant, quality of internal fixation, type of living accommodation, and pre-fracture mobility.

Conclusion

Internal fixation has been found to be an effective option in elderly patients with undisplaced fractures regardless of their specific age, cognitive ability or physical condition. In displaced fractures the reoperation rate was found to be high, therefore a primary hip replacement should be recommended.

Effect of Combining Operating Room Nursing Based on Clinical Quantitative Assessment with WeChat Health Education on Postoperative Complications and Quality of Life of Femoral Fracture Patients Undergoing Internal Fixation

Objective

To explore the effect of combining operating room nursing based on clinical quantitative assessment with WeChat health education on postoperative complications and quality of life (QOL) of femoral fracture patients undergoing internal fixation.

Methods

Ninety femoral fracture patients treated in our hospital (July 2018 to July 2021) were chosen as the research objects and split into the control group (routine intervention) and the study group (combination of operating room nursing based on clinical quantitative assessment and WeChat health education) according to the nursing intervention modes, with 45 cases each. After nursing, the postoperative complications and QOL of patients were compared between the two groups.

Results

No statistical between-group differences in general data were observed (P > 0.05); the hospital stay, weight-bearing time, and fracture healing time were obviously shorter in the study group than in the control group (P < 0.05); 1 d after surgery, the VAS pain status was not significantly different between the two groups (P > 0.05), and 2 d and 3 d after surgery, the VAS scores were significantly lower in the study group than in the control group (P < 0.05); 1 d after surgery, the Harris scores of patients in the two groups were close and did not present statistical difference (P > 0.05), and 8 weeks after surgery, the Harris score was significantly higher in the study group than in the control group (P < 0.05); the scores on self-care agency such as self-concept, self-care skills, sense of self-care responsibility, and health knowledge level were significantly higher in the study group than in the control group (P < 0.05); compared with the control group, the probability of occurring incision infection, lung infection, pressure sore, swelling and pain, and other complications was significantly lower in the study group (P < 0.05).

Conclusion

Implementing operating room nursing based on clinical quantitative assessment combined with WeChat health education to femoral fracture patients undergoing internal fixation can effectively improve their postoperative clinical indicators, reduce their postoperative pain sensation and complication incidence, and effectively promote the joint motion range, which is conducive to enhancing their self-care agency and QOL.

Seasonality in surgical outcome data: a systematic review and narrative synthesis

BACKGROUND

Seasonal trends in patient outcomes are an under-researched area in perioperative care. This systematic review evaluates the published literature on seasonal variation in surgical outcomes worldwide.

METHODS

MEDLINE, Embase, Cochrane, CINHAL, and Web of Science were searched for studies on major surgical procedures, examining mortality or other patient-relevant outcomes, across seasonal periods up to February 2019. Major surgery was defined as a procedure requiring an overnight stay in an inpatient medical facility. We included studies exploring variation according to calendar and meteorological seasons and recurring annual events including staff turnover. Quality was assessed using an adapted Downs and Black scoring system.

RESULTS

The literature search identified 82 studies, including 22 210 299 patients from four continents. Because of the heterogeneity of reported outcomes and literature scope, a narrative synthesis was undertaken. Mass staff changeover was investigated in 37 studies; the majority (22) of these did not show strong evidence of worse outcomes. Of the 47 studies that examined outcomes across meteorological or calendar seasons, 33 found evidence of seasonal variation. Outcomes were often worse in winter (16 studies). This trend was particularly prominent amongst surgical procedures classed as an 'emergency' (five of nine studies). There was evidence for increased postoperative surgical site infections during summer (seven of 12 studies examining this concept).

CONCLUSION

This systematic review provides tentative evidence for an increased risk of postoperative surgical site infections in summer, and an increased risk of worse outcomes after emergency surgery in winter and during staff changeover times.

Bipolar hemiarthroplasty for the treatment of femoral neck fractures with minimally invasive anterior approach in elderly

OBJECTIVES

The purpose of the study was to evaluate the efficacy of hemiarthroplasty with minimally invasive direct anterior approach (DAA) for the treatment of femoral neck fracture in elderly patients. We aimed to compare the DAA and the standard anterolateral approach (ALA), assessing multiple peri‑ and post-operative parameters.

DESIGN AND SETTING

Between December of 2015 and May of 2017, patients operated with medial femoral neck fractures using bipolar hemiarthroplasty with DAA or ALA were evaluated. The volume of bleeding and transfusion, postoperative level of pain, mobilisation and functional outcome were assessed retrospectively.

PARTICIPANTS

Patients between the age of 75 and 85, suffering Garden Type III Pauwels Type III and Garden Type IV medial femoral neck fractures were entered to the study. Patients had no history of anticoagulant therapy; the operation was performed in the first 48 h. All patients received similar postoperative pain management and physiotherapy. The type of implants was determined by the patients' bone morphology and quality.

MAIN OUTCOME MEASURES

The outcomes of interest were the level of postoperative pain, blood loss, rate of recovery and physiotherapy, altered gait pattern and accuracy of leg length, related to DAA and ALA techniques.

RESULTS

The 51 patients operated with DAA showed significantly less pain, based on VAS (visual analogue scale), starting of the first postoperative day. Those patients who were subjected to DAA met with the criteria of hospital discharge 1.68 days earlier, compared to ALA patients. The length of leg was accurately set in 21% of ALA vs 54.9% of DAA patients. On the 12th week follow-up, limping was detected only 5.9% of DAA vs 46% of ALA groups. On the postoperative 2nd and 6th weeks, the HHS (Harris Hip Score) was significantly better in patients with DAA, compared to ALA (77 vs 65 and 91 vs 77, p < .05).

CONCLUSION

The bipolar hemiarthroplasty with DAA allows earlier mobilisation, reduced postoperative pain and need for rehabilitation with an overall better functional outcome, compared to ALA. DAA is proven a reliable choice for femoral neck fractures, offering good outcome and faster recovery, similarly to total hip arthroplasties with degenerative arthritis.

Non-operative predictors for subsequent interventions after intracapsular femoral neck fractures in elderly: A comprehensive analysis of the Hungarian nationwide health insurance database

OBJECTIVES

To investigate the correlation between non-operative prognostic factors and non-prosthetic fracture-related treatments following internal fixation of intracapsular femoral neck fractures in elderly patients.

DESIGN AND SETTING

Retrospective observational cohort study. Comprehensive analysis of the Hungarian nationwide health insurance database.

PARTICIPANTS

Data of in-patient records with S7200 ICD-10 codes were collected from the Hungarian National Health Insurance Fund Administration (HNHIFA) and from the health care provider institutes. The patients with femoral neck fractures in the year of 2000, following reduction and internal fixation aged 60 years or older were evaluated. The secondary, non-prosthetic fracture related treatments during the 8 year follow-up period were registered.

MAIN OUTCOME MEASURES

Of the prognostic factors, age, gender, type of fracture, season and day of the primary surgery, length of waiting time to the operation and the accompanied diseases were evaluated as risk factors for all type of fracture-related further interventions, with the exception of arthroplasties.

RESULTS

A total of 2895 patients with intracapsular femoral neck fractures met the study criteria. The mean age was 77.96 years (SD: 8.54). The cohort of the patients was observed for a total of 10,077.8 person-years. The non-prosthetic fracture related treatment was performed in 265 patients (9,2%); the median of the time elapsed to the secondary definitive treatment was 3.5 months. With Cox regression analysis, significant correlation was revealed between the incidence of non-prosthetic treatment and younger age (year, HR = 0.977, p = 0.002), surgical delay (12-24 h vs 0-6 h, HR = 1.518, p = 0.023; 24h+ vs 0-6 h, HR = 1.372, p = 0.050), season of primary osteosynthesis (fall vs summer, HR = 0.636, p = 0.012), and type of femoral neck fracture (intracapsular displaced vs intracapsular undisplaced, HR = 1.340, p = 0,047). There was no significant effect of the day of primary surgery, the gender and the presence of co-morbidities on the incidence of further surgical interventions.

CONCLUSION

The summertime primary surgical intervention, delay of surgery longer than 12 h and type of femoral neck fracture are independent predictors of non-prosthetic further treatment of femoral neck fractures in elderly patients.

Seasonal variation in trauma admissions to a level III trauma unit over 10 years

INTRODUCTION

Major trauma centres have improved morbidity and mortality for moderate and severely injured patients. Less injured patients may be treated in facilities less resourced for trauma care. In these units, understanding the variations in injury presentation and treatment over time allows service delivery to be tailored to demand. This study set out to describe seasonal variations in trauma over a 10-year period at a level III trauma unit.

MATERIALS AND METHODS

Patient demographics, admission frequency, site of injury, season of admission, management, complications, onward transfers, and length of stay were extracted on consecutive patients admitted with traumatic injuries between January 2009 and December 2018 and recorded on a prospectively maintained database. Analysis was undertaken to determine if there were reproducible patterns in trauma presentation across seasons, based on the patient's age and gender, type of injury, management and length of stay.

RESULTS

There were 13,007 'first admissions' over 10 years, with a mean (SD) age of 55.6 (27.7) years. Admissions were higher in summer (27%) and lower in winter (23.6%) and patients were on average younger in the summer (52.8 years) and older in winter (59.2 years). The proportion of female and male patients remained relatively constant across seasons (CV=6% and 8%, respectively). There was seasonal variation in the incidence of forearm (36%) elbow (19%), and multi-sites injuries (17%) compared with hip and wrist injuries (CV=5% for both). A lower proportion of patients underwent operations in summer (72%) compared with other seasons with winter having the highest at 77%. More patients aged less than 60 years stayed in hospital during winter than summer (13.2% vs. 11.6-12.4%) although often for a day. Patients aged 60 years stayed longer in spring and winter.

CONCLUSION

The results of this study demonstrate trends in the admission and management of trauma patients to a level III trauma unit. Some of the patterns in admission, treatment and length of stay had not been identified previously. The results can be used to enhance patient care and minimise health care costs by reducing unwarranted variations and enabling service delivery to match the demand in all trauma units.

Donor KIR2DS1 reduces the risk of transplant related mortality in HLA-C2 positive young recipients with hematological malignancies treated by myeloablative conditioning

Background

Recognition of HLA-C2 group alleles on recipient cells by activating killer immunoglobulin like receptors, KIR2DS1 on donor natural killer cells may lead to increased graft-versus-leukemia effect or immunomodulation in patients treated by allogeneic hematopoietic stem cell transplantation (allo-HSCT) influencing disease free and overall survival (OS).

Objective

In the present study, 314 consecutive, allo-HSCT recipient and donor pairs were included with retrospective donor KIR-genotyping and clinical parameters analyzes.

Results

After a median follow-up of 23.6 months, recipients with HLA-C2 group allele (rC2) showed improved (p = 0.046) OS if transplanted with KIR2DS1 positive donors (d2DS1) compared to those without one or both of this genetic attribute. Within the myeloablative conditioning (MAC) subgroup (n = 227), rC2 homozygous+d2DS1 patients (n = 14) showed a 5 years OS of 93% followed by rC2 heterozygous+d2DS1 patients (n = 48, 65%) compared to rC2 and/or d2DS1 negatives (47%, p = 0.018). Multivariate analyses indicated rC2+d2DS1 positivity as an independent predictor of OS (HR:0.47, 0.26–0.86, p = 0.014) besides donor type, presence of CMV-reactivation or chemoresistant disease. Among MAC-treated patients, the combined rC2+d2DS1 presence was associated with a markedly decreased cumulative incidence of transplant related mortality (p = 0.0045).

Conclusion

The combination of rC2+d2DS1 may be a favorable genetic constellation in allo-HSCT with MAC potentially reducing transplant related mortality.

Seasonality of Periprosthetic Femur Fractures in 12,700 Primary and Revision Total Hip Arthroplasties

BACKGROUND

Periprosthetic femur fractures after primary and revision total hip arthroplasty (THA) are one of the most common long-term reasons for reoperation after THA. Previous investigations have analyzed the incidence and risk factors of these fractures. No previous study, however, has analyzed a variation in periprosthetic femur fractures between meteorologic seasons. The aim of this study was to compare the incidence of periprosthetic femur fractures after primary and revision THAs depending on the meteorologic season.

METHODS

We identified 8920 patients (10,672 hips) who underwent primary THAs and 1830 patients (1998 hips) who underwent revision THAs at our institution between 1995 and 2011. All patients resided in the Upper Midwest at the time of surgery. Patients who experienced periprosthetic femur fractures were identified and categorized based on the meteorologic season. A Cox model was used to assess the association of seasonality with the risk of fracture.

RESULTS

During the study period, 165 primary THAs and 80 revision THAs sustained a periprosthetic femur fracture. Using winter as a reference, the risk of a periprosthetic femur fracture after primary THA was not statistically higher in the spring (hazard ratio [HR] = 1.3; P = .2), autumn (HR = 1.4; P = .2), and summer (HR = 1.415; P = .1). Similarly, the risk of periprosthetic femur fracture after revision THA was not statistically higher in the spring (HR = 0.9; P = .6), autumn (HR = 0.6; P = .1), and summer (HR = 0.9; P = 1.0).

CONCLUSION

The risk of periprosthetic femur fracture after primary and revision THA does not significantly differ between meteorologic seasons.

Seasonal Variation in Hip Fracture Mortality

Objectives:

This study aims to identify if wintertime surgery increases the mortality of the patients after hip fracture operations.

Design:

Retrospective observational cohort study.

Setting:

The data for this citywide retrospective observational cohort study came from Clinical Data Analysis Reporting System.

Patient:

This study included 35 409 patients with hip fracture operations from July 2005 to December 2013.

Main Outcome Measures:

Cox regression hazard model was used to estimate the independent effect of operation being performed in winter on the hazard of mortality. The hazard model included covariates found to be independent predictors of mortality: age, sex, surgical delay, and Charlson Comorbidity Index (CCI).

Results:

There was a seasonal variation with more hip fracture operations happening in the winter months. The 1-month, 6-month, 1-year, and 5-year mortality were 3%, 11%, 17%, and 47%, respectively. Operation performed in winter was associated with a higher hazard of mortality (hazard ratio [HR] 1.040; 95% confidence interval: 1.010-1.072; P = .009). The HR was greater with male sex (HR 1.786; P = .000), advanced age (≥85 years old: HR 2.819; P = .000), the longer surgical delay (HR 1.018; P = .000), and higher CCI (severe CCI group: HR 2.963; P = .000).

Conclusion:

Wintertime hip fracture surgery was associated with an increased hazard of mortality after adjusting for other known risk factors affecting mortality post hip fracture operations.

Do 25-Hydroxyvitamin D Levels Correlate With Fracture Complications?

OBJECTIVES

To determine the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels and the likelihood of postoperative complications and fracture reoperation rate in orthopaedic trauma patients receiving vitamin D and calcium supplementation.

DESIGN

Retrospective case series.

SETTING

Level I trauma center, Midwestern United States.

PATIENTS

All orthopaedic trauma patients-18 years or older-over a 20-month period were included with available initial and repeat 25(OH)D serum levels. In total, 201 patients met inclusion criteria.

INTERVENTION

All patients received 1000 IU of vitamin D3 and 1500 mg of calcium daily. Vitamin D deficient and insufficient patients also received 50,000 IU of ergocalciferol (vitamin D2) weekly until 25(OH)D levels normalized or fractures healed.

MAIN OUTCOME MEASUREMENTS

fracture complications and 25(OH)D levels.

RESULTS

Fifteen patients experienced postoperative healing complications. There was no significant difference between initial (P = 0.92) or repeat (P = 0.91) 25(OH)D levels between patients with and without fracture healing complications. Twenty-eight patients required repeat orthopaedic surgery. There was no significant difference between initial (P = 0.62) or repeat (P = 0.18) 25(OH)D levels between patients who did or did not require repeat orthopaedic surgery. There was no significant difference between initial (P = 0.66) or repeat (P = 0.89) 25(OH)D levels between patients who did or did not require nonorthopaedic surgery.

CONCLUSIONS

Serum 25(OH)D levels did not significantly affect the likelihood of fracture healing complications requiring surgery or any nonorthopaedic injury-related surgery.

Pre-fracture quality of life predicts 1-year survival in elderly patients with hip fracture-development of a new scoring system

Hip fractures are common in elderly people. Despite great progress in surgical care, the outcome of patients with hip fracture remains disappointing. This study determined four prognostic factors (lower ASA score, higher pre-fracture EQ-5D index, higher MMSE score, and female gender) to predict 1-year survival in patients with hip fracture.

INTRODUCTION

This study determined the prognostic factors for 1-year survival in patients with hip fracture. Based on these predictors, a scoring system was developed for use upon patients' admission to the hospital.

METHODS

Hip fracture patients, aged ≥60 years, were prospectively enrolled. Upon admission, patients' sociodemographic data, type of fracture, American Society of Anesthesiologists (ASA) score, health-related quality of life scores (EQ-5D index) and Mini-Mental State Examination (MMSE) scores were recorded, among other parameters. Correlational analysis was performed on all potential variables to identify relevant predictor variables of 1-year survival. Univariate regression analysis was performed on all selected variables, followed by a multivariate analysis for variables that were significant in the univariate analysis. The final score was developed by converting the β-coefficients of each variable from the multivariate analysis into a scoring system.

RESULTS

For 391 hip fracture patients, complete data were available at the time of the 1-year follow-up. In multivariate regression analysis, independent predictors of 1-year survival were lower ASA score, higher pre-fracture EQ-5D index, higher MMSE score, and female gender. The different variables were weighted according to their β-coefficient to build the prognostic score, which ranged from 0 to 10 points. The ROC curve for 1-year mortality after hip fracture showed an area under the curve of 0.74 (R (2) = 0.272; 95 % CI 0.68-0.79; p < 0.001).

CONCLUSIONS

With only four instruments, the new score represents a useful tool for estimating 1-year survival in elderly patients with hip fractures. At present, the score is limited due to a lack of validation. A validation study is currently underway to prove its reliability.
