Outcomes of ultra-old vs old patients after hip fracture surgery: a matched cohort analysis of 1524 patients

Quality of cementing in hemiarthroplasty for elderly neck of femur fractures does not affect short term functional outcomes

INTRODUCTION

Cemented hip hemiarthroplasty is a routine surgical option for elderly neck of femur (NOF) fractures. It is uncertain if quality of cementing has any effect on functional outcomes. The aim of this study was to determine if the quality of cementing would affect short term functional outcomes in elderly neck of femur fractures.

MATERIALS AND METHODS

Retrospective analysis of 637 single-centre cemented hip hemiarthroplasties from 2014 to 2021 was performed. Each post-operative radiograph was double-read by 2 authors (1 resident and 1 fellowship trained surgeon) to determine quality of cementing via the Barrack grading. Disagreements were reviewed by a third reader. Cement grades were grouped as Optimal (Barrack grade A-B), or Suboptimal (Barrack grade C-D). Functional outcomes were compared using mobility (community- or home-ambulant), assistance required for mobility, and Modified Barthel Index (MBI). Surgical parameters were compared between the groups.

RESULTS

There were 429 Optimal and 208 Suboptimal cases of cementing performed. There was no difference in age, American Society of Anesthesiologists score, mobility, assistance required, and MBI score pre-operatively (p > 0.05). Patients in the "Suboptimal" cementing group had a higher Charlson Comorbidity Index (CCI) score (p < 0.001). At 1 year post-operation, there was no significant difference between "Optimal" and "Suboptimal" cementing with regards to the proportion of community ambulators (30.2% vs. 25.7%, p = 0.252), walking independence (independent walkers (19.8% vs.17.3%), independent walkers with aids (41.3%vs.42.1%), walker with caregiver assistance (29.2%vs.33.7%), wheelchair-bound (9.6%vs.6.9%), p = 0.478), and distribution of MBI score (81.1%vs.82.2% achieving MBI > 60, p = 0.767). There was no significant difference in the proportion of patients with postoperative delirium (7.9% vs. 5.8, p = 0.324) or 1-year mortality rates (3.5% vs. 2.9%, p = 0.685). Except for stem design (12.2% tapered vs 20.1% collared; p = 0.011), no other surgical parameters were significantly different. The kappa value for inter-reader agreement was "substantial" at 0.727 (95% CI 0.682-0.772) (p < 0.001).

CONCLUSION

Quality of cementing in cemented hip hemiarthroplasty for elderly NOF fractures does not affect the short-term functional outcomes. In low demand patients and patients at risk of BCIS, optimal cementing may not be necessary to achieve similar short-term functional outcomes. Further studies should be conducted to determine the effect of sub-optimal cementing on long-term functional outcomes.

Efficacy of surgical intervention over conservative management in intertrochanteric fractures among nonagenarians and centenarians: a prospective cohort study

BACKGROUND

Optimal treatment strategy for nonagenarians and centenarians with hip fractures (NCHF) remained unknown. The authors aimed to compare the outcomes of surgical and conservative management in NCHF.

METHODS

A prospective cohort study was conducted based on CPMHF database with NCHF patients hospitalized during 2014-2020. Comorbidities were evaluated by mECM score and restricted cubic spline was utilized to visually assess the dose-effect relationship between the mECM and outcomes. Propensity score matching was performed to balance baseline characteristics between nonsurgical and surgical groups. Multivariate logistic regression, Cox proportional hazard analysis, and survival analysis were employed for unfavorable outcomes (UFO) evaluation. Competing risk of death were analyzed based on Fine and Gray's hazard model and then constructed nomogram models for predicting survival rates. Subgroup analyses were used to determine potential population heterogeneity and sensitivity analyses were performed to test robustness of the results.

RESULTS

The authors found increasing trends for UFO with the increase in the mECM score, and that high mECM score (HMS, ≥3) was independently associated with a 2.42-fold (95% CI: 2.07-3.54; P =0.024) increased risk of UFO, which remained significant after considering the competing role of death and were more pronounced in nonsurgical treatment, women, no insurance, and patients with spouse (all P for interaction <0.05). Surgical intervention was identified to be significant protective factors for UFO (RR, 0.59; 95% CI: 0.46-0.75; P <0.001) and severe complications (RR, 0.63; 95% CI: 0.41-0.96; P =0.033) after propensity score matching, as well as survival (HR, 0.40, 95% CI: 0.28-0.58; P <0.001), which remained significant after considering the competing role of death and in all sensitivity analyses and were more pronounced in HMS participants ( P for interaction=0.006). Subgroup analyses revealed surgical patients with HMS had a significantly higher UFO rate (excluding death, P <0.001) while nonsurgical patients with HMS had higher mortality rate as compared to the others ( P =0.005).

CONCLUSION

Surgical treatment for NCHF yields better outcomes compared to conservative treatment.

Risk factors for urinary tract infection in geriatric hip fracture patients: a systematic review and meta-analysis

Background

Urinary tract infection (UTI) is a prevalent and consequential complication in hip fracture patients, leading to significant disability and heightened healthcare expenditures. Consequently, there is a critical need for a comprehensive systematic review to identify risk factors and establish early and effective preventive measures.

Methods

A comprehensive search was performed across the PubMed, Cochrane, Embase, Web of Science, and Scopus databases (up to August 31, 2023). Article screening, data extraction, and quality assessment were independently completed by two reviewers.

Results

Forty-four studies were eligible for inclusion, yielding an overall incidence rate of 11% (95% CI: 8%-14%). Our pooled analysis revealed 18 significant risk factors, including being female (OR = 2.23, 95% CI: 1.89-2.63), advanced age (MD = 1.35, 95% CI: 0.04-2.66), obesity (OR = 1.21, 95% CI: 1.11-1.31), catheterization (OR = 3.8, 95% CI: 2.29-6.32), blood transfusion (OR = 1.39, 95% CI: 1.21-1.58), American Society of Anesthesiologists ≥III (OR = 1.28, 95% CI: 1.18-1.40), general anesthesia (OR = 1.26, 95% CI: 1.11-1.43), intertrochanteric fracture (OR = 1.25, 95% CI: 1.01-1.54), hemiarthroplasty (OR = 1.43, 95% CI: 1.19-1.69), prolonged length of hospital stay (MD = 1.44, 95% CI: 0.66-2.23), delirium (OR = 2.66, 95% CI: 2.05-3.47), dementia (OR = 1.82, 95% CI: 1.62-2.06), Parkinson's disease (OR = 1.53, 95% CI: 1.46-1.61), diabetes (OR = 1.27, 95% CI: 1.13-1.43), hypertension (OR = 1.14, 95% CI: 1.03-1.26), congestive heart failure (OR = 1.35, 95% CI: 1.10-1.66), history of sepsis (OR = 7.13, 95% CI: 5.51-9.22), and chronic steroid use (OR = 1.29, 95% CI: 1.06-1.57).

Conclusion

Our study identifies numerous risk factors strongly associated with UTI, offering compelling evidence and actionable strategies for improving clinical prediction, enabling early intervention, and facilitating targeted UTI management.

In-hospital outcomes following primary and revision total hip arthroplasty in nonagenarian patients

PURPOSE

The primary goal of this study was to assess the risk of postoperative surgical and medical complications and problems among nonagenarian patients operated with hip arthroplasty.

METHODS

Data from a specific high-volume arthroplasty clinic, were collected to evaluate postoperative morbidity and complication rates after hip arthroplasty in nonagenarians, compared with a control group of younger, but similar patients. Outcomes evaluated included length of stay, transfusion rate, and postoperative medical and surgical complication rates.

RESULTS

A total of 97 nonagenarian patients (mean age 91.4 years) were included, and compared with 89 control group patients (mean age 70.18 years). Nonagenarian patients had significantly longer length of stay (11.44 vs. 7.98 days, p < 0.01), significantly higher risk of needing a transfusion (11.30% vs. 3.40%, p = 0.04), and significantly higher risk of a postoperative medical complication (28.90% vs. 11.20%, p = 0.03). There was no difference in postoperative surgical complication rate (7.20% vs. 2.20%, p = 0.12).

CONCLUSION

Nonagenarian patients, when compared to a younger control group, experience significantly longer hospital stays, and risk of non-surgical complications. Arthroplasty in nonagenarian patients carries with it a high risk of complications, and thus careful pre-operative evaluation and the care of these patients at high volume, specialized clinics is important to optimize outcomes.

Operative Versus Nonoperative Management of Unstable Spine Fractures in the Elderly: Outcomes and Mortality

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To assess outcomes and mortality in elderly patients following unstable spine fractures depending on treatment modality.

SUMMARY OF BACKGROUND DATA

Operative management of unstable spine fractures in the elderly remains controversial due to increased risk of perioperative complications. Mortality rates after operative versus nonoperative treatment of these injuries have not been well-characterized.

MATERIALS AND METHODS

Patients aged above 65 with unstable spine fractures without neurologic injury from 2015 to 2021 were identified from the Clinformatics ® Data Mart (CDM) Database. Demographics, complications, and mortality were collected. Multivariable logistic regression was used to adjust for the effect of baseline characteristics on mortality following unstable fracture diagnosis.

RESULTS

Of the 3688 patients included, 1330 (36.1%) underwent operative management and 2358 (63.9%) nonoperative. At baseline, nonoperative patients were older, female, had higher Elixhauser comorbidity scores, and were more likely to have a cervical fracture. Operative patients had a longer length of stay in the hospital compared with nonoperative patients (9.7 vs. 7.7 days; P <0.001). Although patients in the operative group had higher rates of readmission at 30, 60, 90, and 120 days after diagnosis ( P <0.01), they had lower mortality rates up to five years after injury. After adjusting for covariates, nonoperative patients had a 60% greater risk of mortality compared with operative patients (hazard ratio: 1.60, 95% confidence interval: 1.40-1.78, P <0.001). After propensity score matching, operative patients age 65 to 85 had greater survivorship compared with their nonoperative counterparts.

CONCLUSIONS

Elderly patients with an unstable spine fracture who undergo surgery experience lower mortality rates up to five years postdiagnosis compared with patients who received nonoperative management, despite higher hospital readmission rates and an overall perioperative complication rate of 37.3%. Operating on elderly patients with unstable spine fractures may outweigh the risks and should be considered as a viable treatment option in appropriately selected patients.
