Background: Periprosthetic fractures can be devastating complications after total joint arthroplasty (TJA). The management of periprosthetic fractures is complex, spanning expertise in arthroplasty and trauma. The purpose of this study was to examine and project trends in the operative treatment of periprosthetic fractures in the United States., Methods: A large, public and private payer database was queried to capture all International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for periprosthetic femoral and tibial fractures. Statistical models were created to assess trends in treatment for periprosthetic fractures and to predict future surgical rates. An alpha value of 0.05 was used to assess significance. A Bonferroni correction was applied where applicable to account for multiple comparisons., Results: In this study, from 2016 to 2021, 121,298 patients underwent surgical treatment for periprosthetic fractures. There was a significant increase in the total number of periprosthetic fractures. The incidence of periprosthetic hip fractures rose by 38% and that for periprosthetic knee fractures rose by 73%. The number of periprosthetic fractures is predicted to rise 212% from 2016 to 2032. There was a relative increase in open reduction and internal fixation (ORIF) compared with revision arthroplasty for both periprosthetic hip fractures and periprosthetic knee fractures., Conclusions: Periprosthetic fractures are anticipated to impose a substantial health-care burden in the coming decades. Periprosthetic knee fractures are predominantly treated with ORIF rather than revision total knee arthroplasty (TKA), whereas periprosthetic hip fractures are predominantly treated with revision total hip arthroplasty (THA) rather than ORIF. Both periprosthetic knee fractures and periprosthetic hip fractures demonstrated increasing trends in this study. The proportion of periprosthetic hip fractures treated with ORIF relative to revision THA has been increasing., Level of Evidence: Prognostic Level III.

Background: Geriatric femoral neck fractures are associated with substantial morbidity and medical cost. We evaluated the incidence and management trends of femoral neck fractures in recent years in the U.S., Methods: Patient data from 2003 through 2013 were obtained from the Nationwide Inpatient Sample database. Femoral neck fractures in patients ≥65 years old were identified and grouped using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure codes for internal fixation, hemiarthroplasty, or total hip arthroplasty (THA). The nationwide incidence of femoral neck fractures was calculated and presented as an age-adjusted population rate. Univariable methods were used for trend analysis and comparisons between groups. Logistic regression modeling was used to analyze complications., Results: From 2003 to 2013, we identified 808,940 femoral neck fractures in patients ≥65 years old. The national age-adjusted incidence of femoral neck fractures decreased from 242 per 100,000 U.S. adults in 2003 to 146 in 2013. The proportion of fractures managed operatively with THA increased over time (5.9% in 2003 versus 7.4% in 2013; p < 0.001). Concurrently, the use of hemiarthroplasty declined (65.1% versus 63.6%; p < 0.001). In 2013, the median age of the patients treated with THA was significantly younger (77.3 years) compared with that in the hemiarthroplasty and internal fixation groups (83.2 and 82.0 years). The THA group had significantly higher median initial hospital costs ($17,097) compared with the hemiarthroplasty and internal fixation groups ($14,776 and $10,462)., Conclusions: In the last decade, the total number and population rate of femoral neck fractures in the elderly declined significantly. There was a modest but significant increase in the utilization of THA., Clinical Relevance: This report identifies the changing trends in clinical practice in the treatment of geriatric femoral neck fractures in the U.S. Treating physicians should be aware of these trends, which include a decreasing national incidence of geriatric femoral neck fractures as well as an increase in the use of THA.

Background: The purpose of this study was to investigate the trends in operative management of femoral neck fractures by orthopaedic surgeons applying for board certification., Methods: We queried the American Board of Orthopaedic Surgery database to identify all femoral neck fractures that had been treated and reported by candidates taking Part II of the licensing examination from 1999 to 2011 to determine the utilization of internal fixation, hemiarthroplasty, and total hip arthroplasty. The longitudinal trends were then stratified by patient age (younger than sixty-five, sixty-five to seventy-nine, eighty and older) and the declared subspecialty of the candidate., Results: There were 19,541 femoral neck fractures that had been treated by 4450 board certification candidates. The use of total hip arthroplasty increased over time (0.7% of fractures in 1999, 7.7% in 2011, p < 0.001); use of hemiarthroplasty (67.1% in 1999, 63.1% in 2011, p = 0.020) and internal fixation (32.2% in 1999, 29.2% in 2011, p = 0.064) declined slightly. All geographic regions showed an increase in utilization of total hip arthroplasty, with substantial variation between locations. The proportion of patients younger than age sixty-five who were managed with total hip arthroplasty increased from 1.4% to 13.1% (p < 0.001). Candidates with a declared subspecialty of "adult reconstruction" showed a strong trend toward the use of total hip arthroplasty (4.3% from 1999 to 2002, 21.1% from 2009 to 2011, p < 0.001), while "trauma" subspecialty candidates demonstrated decreasing utilization of internal fixation (40.9% from 1999 to 2002, 32.9% from 2009 to 2011, p = 0.012). The percentage of candidates treating at least one femoral neck fracture decreased from 54.8% from 1999 to 2002 to 46.3% from 2009 to 2011 (p < 0.001)., Conclusions: The most substantial changes in treatment of femoral neck fractures were seen in the younger group of patients. Currently, a smaller percentage of board certification candidates are treating femoral neck fractures than those in the past, possibly reflecting a trend toward specialty care., (Copyright © 2014 by The Journal of Bone and Joint Surgery, Incorporated.)

Background: the treatment of proximal humeral fractures in the elderly remains controversial. Options include nonoperative treatment, open reduction with internal fixation (ORIF), and hemiarthroplasty. Locking plate technology has expanded the indications for ORIF for certain fracture types in osteoporotic bone. This study was performed to characterize the incidence, treatment, and revision surgery of proximal humeral fractures according to geographic region both before (1999 to 2000) and after (2004 to 2005) the introduction of locking plates., Methods: we used a 20% sample of Medicare Part-B data and the Medicare denominator file for the years 1998 to 2006. Proximal humeral fractures were identified by Common Procedural Terminology codes for treatment, categorized as nonoperative, ORIF, or hemiarthroplasty. Geographic variation in treatment type was determined with use of 306 hospital referral regions. Odds ratios for revision surgery were calculated by the need for repeat surgery within one year of the index procedure. Rates were adjusted for age, sex, race, and comorbidities., Results: there were 14,774 proximal humeral fractures in the 20% sample from 1999 to 2000 (an estimated total of 73,870 fractures) and 16,138 fractures in the sample from 2004 to 2005 (an estimated total of 80,690 fractures). The overall age, sex, and race-adjusted incidence of proximal humeral fractures was unchanged from 1999 to 2005 (2.47 vs. 2.48 per 1000 Medicare beneficiaries; p = 0.992). However, the absolute rate of surgically managed proximal humeral fractures rose 3.2 percentage points from 12.5% to 15.7%, a relative increase of 25.6% (p < 0.0001). The relative increase in the percentage of fractures treated with ORIF was 28.5% (p < 0.0001), while the percentage of fractures treated with hemiarthroplasty increased 19.6% (p < 0.0001). There were large regional variations in the proportion treated surgically (range, 0% to 68.18%). The rates of repeat surgery were significantly higher in 2004 to 2005 compared with 1999 to 2000 (odds ratio = 1.47, p = 0.043)., Conclusions: although the incidence of proximal humeral fractures in the elderly did not change from 1999 to 2005, the rate of surgical treatment increased significantly. The marked regional variation in the rates of surgical treatment highlights the need for better consensus regarding optimal treatment of proximal humeral fractures. Additional research is needed to help to determine which fractures are best treated operatively in order to maximize outcome and minimize the need for revision surgery., Level of Evidence: therapeutic Level II.
