Low-Demand Cemented Femoral Stem Designs and Revision Risk Following the Hemiarthroplasty Treatment of Geriatric Hip Fracture.

Background: Cemented fixation is recommended in the hemiarthroplasty treatment of geriatric femoral neck fractures. Certain cemented stems have similarly designed "low-demand" counterparts, but it is unclear whether they yield comparable clinical outcomes. The purpose of this study was to evaluate the revision risk associated with two low-demand stems, Summit Basic (DePuy Synthes) and Versys LD/Fx (Zimmer Biomet), in comparison to their standard counterparts, Summit (DePuy Synthes) and Versys Advocate (Zimmer Biomet).

Are There Differences in Performance Among Femoral Stem Brands Utilized in Cementless Hemiarthroplasty for Treatment of Geriatric Femoral Neck Fractures?

Background: For the vast majority of displaced femoral neck fractures in older patients, cemented femoral fixation is indicated because it is associated with a lower risk of periprosthetic fracture than cementless fixation. Nevertheless, cementless fixation continues to be utilized with high frequency for hip fractures in the United States. It is therefore helpful to understand the performance of individual cementless brands and models.

Direct Anterior Versus Posterior Approach for Total Hip Arthroplasty Performed for Displaced Femoral Neck Fractures.

Objectives: To compare perioperative, 90-day, and 1-year postoperative complications and outcomes between the direct anterior approach (DAA) and the posterior approach for total hip arthroplasty in geriatric patients with displaced femoral neck fractures (FNFs).

Design: Retrospective cohort study.

Setting: Multicenter Health care Consortium.

Sex- and ethnic-specific patterns in the incidence of hip fracture among older US Asian and non-Hispanic White adults.

Background: Asian and Pacific Islander (Asian/PI) adults have lower hip fracture incidence than non-Hispanic White (NHW) adults, but data regarding Asian/PI subgroups are limited. We compared hip fracture incidence among older US Asian/PI and NHW populations, including ethnic subgroup differences.

Methods: Using observational data from a California healthcare system, we identified Asian/PI and NHW adults aged ≥50 years (2000-2019) and followed subjects to 2021 for hip fracture determined by principal/primary hospital diagnosis or by secondary hospital diagnosis with hip/femur procedure codes.

Factors Influencing Patient Satisfaction With Care and Surgical Outcomes for Total Hip and Knee Replacement.

Introduction: Although patient satisfaction with total joint arthroplasty has been a well-measured outcome, little is known about how preadmission and post-discharge care experiences affect patients' rating of satisfaction.

Objective: This work aimed to identify actionable factors associated with better ratings of overall care and surgical results.

Methods: A 36-item survey assessing care in the preoperative, perioperative, and post-discharge phases of care and across all phases was mailed to 7,031 patients who underwent primary unilateral elective total hip arthroplasty and total knee arthroplasty in 2018.

Risk of complete atypical femur fracture with Oral bisphosphonate exposure beyond three years.

Background: Bisphosphonate (BP) therapy has been associated with atypical femur fracture (AFF). However, the threshold of treatment duration leading to increased AFF risk is unclear. In a retrospective cohort of older women initiating BP, we compared the AFF risk associated with treatment for at least three years to the risk associated with treatment less than three years.

The Epidemiology of Metatarsal Fractures Among Older Females With Bisphosphonate Exposure.

Bisphosphonates (BP) are used to treat osteoporosis, although rare atypical femur fractures have occurred with long-term exposure, especially among Asians. Metatarsal fractures have also been reported with atypical femur fracture. We examined the epidemiology of metatarsal fractures among 48,390 females aged ≥50 years who initiated oral BP and were followed for a median 7.

Pediatric Hip Fractures in California: Results from a Community-Based Hip Fracture Registry.

Context: Hip fracture registries offer an opportunity to identify and to monitor patients with rare conditions and outcomes, including hip fractures in pediatric patients.

Objective: To report patient demographics and surgical outcomes of pediatric patients treated surgically for hip fractures in a large integrated health care system.

Design: Pediatric patients (< 21 years old at the time of fracture) with hip fractures were identified between 2009 and 2012 using our health care system's hip fracture registry.

The association of race/ethnicity and risk of atypical femur fracture among older women receiving oral bisphosphonate therapy.

Purpose: Several epidemiologic studies suggest that compared to white women, Asians have a greater propensity to suffer an atypical femur fracture (AFF) while taking bisphosphonate therapy. This study examines the relative risk of AFF following bisphosphonate initiation for Asian compared to white women.

Methods: Using data from a large integrated northern California healthcare delivery system, we examined diaphyseal femur fracture outcomes among women age≥50years old who initiated oral bisphosphonate therapy during 2002-2007.

Trends in mortality following hip fracture in older women.

Objectives: To examine contemporary trends in mortality following hip fracture among older postmenopausal women in an integrated healthcare delivery system.

Study Design: Retrospective cohort study of 13,550 women aged ≥65 years with hip fracture during 2000 to 2010.

Methods: Demographic factors, comorbidity index score, fracture history, early rehospitalization, and all-cause mortality within 1 year following hip fracture were examined using health plan databases and records.

Femur fracture classification in women with a history of breast cancer.

Purpose: Women with breast cancer are at increased risk for femur fracture. Contributing factors include estrogen deficiency, cancer-related therapies, or direct bone involvement. This study examines fracture subtypes in women with prior breast cancer experiencing a femur fracture.

Atypical femur fractures among breast cancer and multiple myeloma patients receiving intravenous bisphosphonate therapy.

Purpose: Atypical femur fractures represent a potential complication of chronic oral bisphosphonate therapy in women with osteoporosis, but the risk of atypical femur fractures among cancer patients receiving intravenous bisphosphonates at higher cumulative doses remains unclear. We examined femur fractures occurring in cancer patients treated with intravenous bisphosphonates (IVBP) to determine whether a subset may be atypical fractures.

Methods: Between 2005 and 2010, we identified patients with known IVBP therapy for multiple myeloma or metastatic breast cancer, who subsequently sustained a femur fracture based on hospitalization, oncology, pharmacy and chemotherapy visit records.

Clinical correlates of atypical femoral fracture.

Background: Reports of atypical femur fracture in bisphosphonate-exposed women have prompted interest in characterizing the clinical profiles of these patients.

Methods: Among women age ≥60 years with hip or femur fracture during 2007-2008, we identified 79 with low-trauma subtrochanteric or femoral shaft fracture. Radiographic images were reviewed to assign fracture pattern and distinguish atypical femur fracture from non-atypical femur fracture.

The in vitro elution characteristics of antifungal-loaded PMMA bone cement and calcium sulfate bone substitute.

The use of antimicrobial-loaded delivery vehicles, most often as antibiotic beads, is common practice for the treatment of deep musculoskeletal infections. The elution of antibacterial drugs from various bone cements has been extensively studied. However, much less is known about the elution of other antimicrobials from these materials.
