J Shoulder Elbow Surg 2024; 33:1699-1708. [PMID: 38522777 DOI: 10.1016/j.jse.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Revised: 01/27/2024] [Accepted: 02/05/2024] [Indexed: 03/26/2024]
Abstract
BACKGROUND Aseptic loosening is one of the most common complications of total elbow arthroplasty (TEA). Modern implants, such as the Nexel, have been designed in an attempt to decrease loosening. The present study aims to report implant survivorship, radiographic assessment of loosening and lucency, and patient-reported outcome measures (PROMs) in patients treated with the Nexel TEA at midterm follow-up. METHODS Consecutive series of adult patients underwent TEA using the Nexel by a single surgeon via standardized technique. Patients with minimum 3-year follow-up with radiographic and PROM data were included. Survivorship was defined by the absence of revision. Loosening was assessed via the Wrightington method by 3 independent fellowship-trained shoulder and elbow surgeons. Lucency was analyzed across individual radiographic zones on orthogonal radiographs. PROMs included the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), Patient-Rated Elbow Evaluation (PREE), and EuroQoL-5 Dimensions (EQ-5D). RESULTS Thirty-eight consecutive patients (22 female, 16 male) with a mean age of 67 years underwent TEA via a triceps-sparing isolated medial window approach. Mean follow-up was 5.5 years (range 3-9). Primary diagnoses were as follows: 19 osteoarthritis (OA), 9 rheumatoid arthritis (RA), 9 post-traumatic arthritis (PA), and 1 conversion of elbow arthrodesis. Overall survivorship was 97.4%, with 1 patient undergoing revision for infection. Loosening was found in 5.3% of elbows, averaged across 3 observers. Lucency was most pronounced at the level of the humeral condyles. PROMs demonstrated significant and clinically meaningful improvements in 76%, 92%, and 73% of patients for QuickDASH, PREE, and EQ-5D, respectively. No significant correlations were found between patient age, gender, loosening, lucency, and PROMs. CONCLUSION At midterm follow-up, the Nexel TEA demonstrated excellent overall survivorship and low rate of implant loosening. The single failure requiring revision for infection was conversion of a prior elbow arthrodesis. PROMs overall exhibited marked and consistent improvement from preoperative to final postoperative follow-up. Although promising, these results should be interpreted with some caution as long-term data regarding this prosthesis are still lacking.

Healthcare (Basel) 2024; 12:1322. [PMID: 38998857 PMCID: PMC11241371 DOI: 10.3390/healthcare12131322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 06/25/2024] [Accepted: 06/27/2024] [Indexed: 07/14/2024] Open
Abstract
This study provides a statistical forecast for the development of total elbow arthroplasties (TEAs) in Germany until 2045. The authors used an autoregressive integrated moving average (ARIMA), Error-Trend-Seasonality (ETS), and Poisson model to forecast trends in total elbow arthroplasty based on demographic information and official procedure statistics. They predict a significant increase in total elbow joint replacements, with a higher prevalence among women than men. Comprehensive national data provided by the Federal Statistical Office of Germany (Statistisches Bundesamt) were used to quantify TEA's total number and incidence rates. Poisson regression, exponential smoothing with Error-Trend-Seasonality, and autoregressive integrated moving average models (ARIMA) were used to predict developments in the total number of surgeries until 2045. Overall, the number of TEAs is projected to increase continuously from 2021 to 2045. This will result in a total number of 982 (TEAs) in 2045 of mostly elderly patients above 80 years. Notably, female patients will receive TEAs 7.5 times more often than men. This is likely influenced by demographic and societal factors such as an ageing population, changes in healthcare access and utilization, and advancements in medical technology. Our projection emphasises the necessity for continuous improvements in surgical training, implant development, and rehabilitation protocols.

Abstract
Background Total elbow arthroplasty (TEA) is a valuable therapeutic approach for improving function and relieving pain in severely deformed elbow joints. However, TEA is associated with a high incidence of complications. In Japan, the use of unlinked TEA has a long history, with the development of the Kudo prosthesis marking a significant milestone. Subsequently, various unlinked implant designs have been developed. Although favorable long-term clinical results have been reported, complications remain a concern. To further improve the outcome of unlinked TEA, attempts have been made in recent years to develop various surgical approaches and intraoperative support devices. This review focuses on the clinical outcomes and recent advances in unlinked TEA in Japan. Methods A comprehensive review of clinical results and advancements in unlinked TEA in Japan was conducted. The analysis included trends in the number of TEA, medium-term and long-term results for unlinked TEA, surgical approaches, or preoperative planning techniques. Results Several implant designs have been developed in Japan. Clinical studies have reported satisfactory long-term outcomes with these implants, but complications, such as infection, fractures, and dislocation, have been observed. In order to enhance the outcomes of unlinked TEA, various triceps-on approaches have been developed as alternatives to the triceps-detaching approach, which compromises the continuity between the triceps tendon and ulna, leading to inevitable complications related to the triceps tendon. Preservation or repair of the surrounding soft tissues is considered critical for preventing postoperative instability due to the absence of a radial head in the current unlinked TEA design. Computed tomography-based 3-dimensional preoperative planning has been pioneered in Japan, demonstrating its effectiveness in predicting implant size and achieving appropriate implant placement. Additionally, augmented reality-assisted surgery is being explored to accurately translate preoperative planning into the surgical procedure. Conclusion Unlinked TEA for inflammatory arthritis has exhibited promising long-term results in Japan, with ongoing efforts to improve surgical techniques and preoperative planning. Further advancements are anticipated to prevent complications such as dislocation and peri-implant fractures.

Abstract
Purpose Compare outcomes of acute versus delayed total elbow arthroplasty (TEA) following distal humerus fractures (DHF). Methods This retrospective study included 39 patients who underwent primary TEA with semiconstrained implants for DHF, either within 4 weeks of their injury or after failing initial open reduction and internal fixation (ORIF) or nonsurgical management, between June 1, 2003 and February 1, 2018 with minimum 1-year follow-up. Our outcome measures included QuickDASH (Disabilities of the Arm, Shoulder, and Hand) score, complications, reoperations, and range of motion (ROM). Demographics, clinical variables, and outcomes were compared using the Student's t-test, Mann-Whitney U test, and Fisher's exact test as appropriate. Kaplan-Meier curves for mortality, implant survivorship, and reoperation were created. Results Our patients were categorized into acute TEA (n = 22), ORIF to TEA (n = 10), and nonsurgical to TEA (n = 7) treatment groups. Additional analysis was performed comparing acute to delayed TEA, which combined data from failed ORIF and nonsurgical cohorts. The median follow-up, average age, and median Charlson comorbility index were similar between groups. The most common fracture pattern was AO13C. At median follow-up of 5.8 years, QuickDASH differed between cohorts: mean of 31 (SD 19) in acute TEA and 52 (SD 27) in delayed TEA, which further subdivided to 44.2 (SD 25) in failed ORIF and 76 (SD 23) in failed nonsurgical management. Poorer QuickDASH scores at final follow-up were associated with delayed TEA, initial nonsurgical management, and depression. Surgical complications were associated with delayed TEA. Higher Charlson comorbidity index was associated with death. No variables were associated significantly with ROM, revision, or reoperation. Conclusion Comminuted DHFs are difficult to treat in the elderly with high rates of complication and poor function after surgery. Our study suggests TEA performed acutely result in satisfactory outcomes and should be a consideration for patients at high risk of failing ORIF or nonsurgical management.

Abstract
HYPOTHESIS Assessing the rotational alignment of the humeral component during total elbow arthroplasty is dependent upon bony landmarks that can be absent or altered in cases of distal humerus fractures, revision arthroplasty, severe bone loss, or deformity. We hypothesize that the intermuscular septum can be used as a reliable soft-tissue landmark to set the rotation of the humeral component intra-operatively when previously described bony landmarks are not reliable or present. MATERIALS AND METHODS Forty-eight unpaired cadaveric human subjects (mean age and standard deviation 63 ± 12 years; 24 males, 24 females) underwent computed tomography (CT) scans. The geometric centers of the trochlea and capitellum were assessed, and the line through these two points was set as the flexion-extension axis (FEA) of the elbow. The intermuscular septum axis (IMSA) was drawn proximal to the olecranon fossa and at least 4 cm proximal to the most distal point of the articular surface, where the posterior humeral cortex was flat. The angles between the FEA and IMSA were calculated and compared using a two-tailed t-test. Regression analysis was used to assess the inter- and intra-observer reliability of the IMSA. RESULTS The IMSA was externally rotated 10.3° ± 2.8 compared to the FEA (p < 0.001 and confidence interval (CI) of 2.8 with α set to 0.01). The inter- and intra-observer reliability of the IMSA was high, with an R-value of 0.91 and 0.97, respectively. CONCLUSIONS The intermuscular septum can be used as a soft-tissue landmark to set humeral component rotation and is 10.3° externally rotated with respect to the FEA of the ulnohumeral joint.

Abstract
BACKGROUND Modification of total elbow arthroplasty (TEA) implants may be necessary in selected patients with substantial anatomic bone deformity or those undergoing revision surgery. The purpose of this study was to investigate the prevalence and consequences of implant modifications during TEA at our institution. We hypothesized that TEA implant modification would be more common in revisions than in primary replacements, and that it would not be associated with worse clinical outcomes or increased rates of radiographic or surgical complications directly related to the implant modification. METHODS Elbows that had undergone TEA by any of 3 surgeons at our institution with use of intraoperative implant modification between January 1992 and October 2019 were retrospectively reviewed for the type of modification and complications. Complications were classified as definitely related, probably related, possibly related, or nonrelated to the implant's modification according to the consensus review by the 3 senior surgeons. A survey was sent out to surgeons outside of our institution to investigate whether intraoperative modification to TEA implants is a common clinical practice. RESULTS A total of 106 implant components were modified during 94 of 731 TEA procedures (13%) in 84 of 560 patients. Implant modifications were performed in 60 of 285 revision cases (21%) compared with 34 of 446 (8%) primary cases (P < .0001). These included shortening the stem in 40 (44%), bending the stem in 16 (15%), notching the stem in 16 (15%), tapering the stem in 9 (9%), and a combination of 2 or more of these modifications in 19 implants (17%). Among the 55 index surgeries available for complication analysis, 40 complications occurred in 28 index surgeries (11 primary and 17 revisions; 25 patients), making the overall complication rate 51%. Of these 40 complications, 23 were considered independent of any implant modification. Of the remaining 17 complications, 9 were considered nonrelated to the implant modification, 6 were possibly related, and 2 were probably related to the implant modification. Therefore, the complication rate possibly related or probably related to implant modification was 15% (8 of 55). No complication was classified as definitely related to the implant modification. No implant breakage or malfunction occurred after any modification. A total of 442 survey responses were received representing 29 countries, of which 144 surgeons (39%) performed modification to implants during TEA procedures. DISCUSSION This study confirmed our hypothesis that modification of TEA implants is not uncommon at our institution, particularly in revision arthroplasty. Surgeons should keep in mind that complications possibly related or probably related to implant modification were at minimum 15% and could have been as high as 30% if the patients lost to follow-up had all had complications. Implant modification may be necessary in some cases but should be exercised with thoughtful consideration and caution.

Abstract
Introduction Total elbow arthroplasty (TEA) is an increasingly popular surgical option for many debilitating conditions of the elbow. There currently exists a paucity of literature regarding patient and hospital factors that lead to inferior outcomes following TEA. The purpose of this study is to identify independent predictors of increased complication and revision rates following TEA. Methods The National Readmissions Database (NRD) was queried from 2011 to 2018 to identify all cases of TEA (n = 8932). Relevant patient demographic factors, comorbidities, and hospital characteristics were identified and run in a univariate binomial logistic regression model. All significant variables were included in a multivariate binomial logistic regression model for data analysis. Results Independent predictors of increased complication rates included age, female sex, Medicare and Medicaid payer status, medium bed-sized center, and 18 of 34 medical comorbidities (all P < .05). Independent predictors of increased revision rates included medium bed-sized centers, non-teaching hospital status, chronic pulmonary disease, depression, and pulmonary circulatory disorders (all P < .05). Conclusion This study identified several patient and hospital characteristics that are independently associated with both increased complication and revision rates following TEA. This information can aid orthopedic surgeons during shared decision making when considering TEA in patients. Level of Evidence Level III, retrospective cohort study.

Abstract
BACKGROUND Medicare and Medicaid are 2 of the largest government-run health care programs in the United States. Although Medicare reimbursement is determined at the federal level by the Centers for Medicare & Medicaid Services, Medicaid reimbursement rates are set by each individual state. The purpose of this study is to compare Medicaid reimbursement rates with regional Medicare reimbursement rates for 12 orthopedic procedures performed to treat common fractures of the upper extremity. METHODS Twelve orthopedic procedures were selected and their Medicare reimbursement rates were collected from the 2020 Medicare Physician Fee Schedule. Medicaid reimbursement rates were obtained from each state's physician fee schedule. Reimbursement rates were then compared by assessing the ratio of Medicaid to Medicare, the dollar difference in Medicaid to Medicare reimbursement, and the difference per relative value unit. The range of variation in Medicaid reimbursement and Medicare wage index-adjusted Medicaid reimbursement was calculated. Comparisons in reimbursement were calculated using coefficient of variation and Student t tests to evaluate the differences between the mean Medicaid and Medicare reimbursements. Two-sample coefficient of variation testing was used to determine whether dispersion in Medicare and Medicaid reimbursement rates differed significantly. RESULTS There was significant difference in reimbursement rates between Medicare and Medicaid for all 12 procedures, with Medicare reimbursing on average 46.5% more than Medicaid. In 40 states, Medicaid reimbursed less than Medicare for all 12 procedures. Regarding the dollar difference per relative value unit, Medicaid reimbursed on average $18.03 less per relative value unit than Medicare. The coefficient of variation for Medicaid reimbursement rates ranged from 0.26-0.33. This is in stark contrast with the significantly lower variability observed in Medicare reimbursement, which ranged from 0.06-0.07. CONCLUSION Our findings highlight the variation in reimbursement that exists among state Medicaid programs for 12 orthopedic procedures commonly used to treat fractures of the upper extremity. Furthermore, average Medicaid reimbursement rates were significantly lower than Medicare rates for all 12 procedures. Such discrepancies in reimbursement may act as a barrier, impeding many Medicaid patients from accessing timely orthopedic care.

Abstract
One of the reasons for failure of total elbow replacement is loosening of the ulnar component. Cementing techniques are often outdated. A special small nozzle is needed for the ulnar component, when a cement gun is used. This may not always be available, or surgeons may prefer to use a syringe. We postulated that the use of a cement gun and smaller nozzle would result in improved filling of the ulnar canal. A cadaveric study was performed in which the ulnas of paired specimens were cemented with a cement gun or with a syringe. A 3D printed ulnar component was inserted and computed tomography scanning was performed on all specimens. Filling of the ulnar intramedullary canal was analysed using 3D reconstructions of the specimens. A greater degree of filling was seen by the use of the cement gun in 85.7%. Filling was 52.7% in the syringe group (25.1-78.7%), compared to 63.3% for the cement gun group (p < 0.05). The use of a small nozzle cement gun provided a significantly higher filling degree of the ulnar canal. We recommend to always use a cement gun with a specific small nozzle to cement the ulnar component in total elbow arthroplasty.

Abstract
BACKGROUND There is very little information in the literature on the outcomes of revision of revision total elbow arthroplasty (RRTEA). Our aim was to report the outcomes of this rarely performed procedure. METHODS We retrospectively identified all patients who had undergone RRTEA between 2007 and 2016. Outcomes were assessed clinically using a number of validated systems, and radiographs were reviewed for prosthesis alignment, cementation by Morrey grading, and heterotopic ossification. RESULTS We identified 22 patients who underwent RRTEA. Of these patients, 14 were available for assessment (2 died of unrelated causes, 2 could not be contacted, 2 declined to participate because of travel difficulties, and 2 had incomplete data). At the final review, the median age was 73 years (range, 57-83 years), with a median follow-up period of 4.5 years (range, 2-7 years) since the last surgical procedure. The median number of previous revision arthroplasty procedures per patient was 3 (range, 2-6). The indications for RRTEA were aseptic loosening (60%), bushing wear (16%), fracture (14%), and infection (10%). Of the patients, 30% required extra-long or custom-made implants and 50% needed allograft augmentation. At final clinical assessment, 56% of patients had triceps insufficiency, the median flexion-extension arc was 90°, and the median prono-supination arc was 95°. The functional elbow scores revealed good outcomes in the majority of patients (median visual analog scale score, 5; median Oxford Elbow Score, 22; median Mayo Elbow Performance Index score, 55; and median QuickDASH [short version of Disabilities of the Arm, Shoulder and Hand questionnaire] score, 63). Eighty-one percent of patients were satisfied with their RRTEAs. Complications included infection in 2 patients (1 superficial and 1 deep), symptomatic aseptic humeral component loosening in 1, sensory ulnar nerve symptoms in 2, and radial nerve injury in 1. One patient required ulnar nerve release. Radiologic review revealed asymptomatic loosening in 1 patient (humeral component), and overall prosthesis alignment with cementation was adequate in 81%. Heterotopic ossification was present in 38% of cases. CONCLUSIONS RRTEA is a satisfactory treatment option in these complex cases, with good short- to mid-term survival rates but a relatively high complication rate.

J Hand Surg Am 2021; 46:552-559. [PMID: 33896647 DOI: 10.1016/j.jhsa.2021.03.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 01/11/2021] [Accepted: 03/11/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE Total elbow arthroplasty (TEA) can be used, with varying degrees of success, for the treatment of rheumatoid arthritis, osteoarthritis, and distal humerus fractures and their sequelae in elderly patients. Some of the largest studies of TEA have included data from more than 20 years ago and may not reflect the current practice of TEA. We sought to describe a modern cohort of patients who underwent TEA in a United States integrated health care system. METHODS All patients aged 18 years and older who underwent primary unilateral TEA from January 1, 2009, through March 31, 2018, were identified to conduct a descriptive study. The patients' characteristics and demographics, including age, body mass index, sex, diabetes status, American Society of Anesthesiologists classification, and surgical indication, were recorded. The crude cumulative revision probability as well as the 90-day postoperative incidence rate of emergency department visit, readmission, and mortality was calculated. RESULTS A total of 170 patients met our inclusion criteria. The annual procedure volume nearly doubled, from 11 procedures in 2009 to 21 procedures in 2017. The most common indication for TEA was fracture (40.6%), followed by rheumatoid arthritis (36.5%). At 4-year follow up, the crude cumulative revision probability was 9.8% (95% confidence interval, 5.6%-16.9%). Of the 170 patients who underwent TEA, 43 (25.3%) experienced a 90-day emergency department visit, 24 (14.1%) experienced a 90-day readmission, and 2 (1.2%) died within 90 days postoperatively. CONCLUSIONS This cohort of patients who underwent TEA using modern implants showed a notable increase in the volume of TEA over the study period, with more TEAs performed for trauma. The incidence of readmission and emergency department visits following TEA were high in this study. Further studies are needed to better define the current practice of TEA in the community at large. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

J Hand Surg Am 2021; 46:27-35. [PMID: 32798123 DOI: 10.1016/j.jhsa.2020.05.029] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 04/24/2020] [Accepted: 05/25/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE We aimed to study the epidemiology of radial head fractures within a single national registry database while analyzing trends in available treatments. METHODS A retrospective analysis of data from 2007 to 2016 provided by a national inpatient database registry was performed using the International Classification of Diseases code for radial head fractures and associated German Procedure Classification (OPS) codes. All surgical interventions were evaluated according to fracture type, patient sex and age, and distribution differences over the last decade to detect changes in the treatment trends. The number of major revision procedures was identified and the revision burden for each procedure calculated. RESULTS Overall, 70,118 radial head fractures were included, with the annual number rising over 20% during this period. Women were significantly older than men (peak incidence, 55-64 years vs 30-39 years) and more frequently injured (women-to-men, 1.3:1). Surgical interventions increased during the study period, with locking plate fixation of comminuted fractures and radial head arthroplasty (RHA) becoming increasingly performed while radial head resections decreased. The revision burden differed significantly between the fixation techniques, with an increased occurrence of RHA revision procedures more recently. CONCLUSIONS The data show a higher number and incidence of surgical procedures, especially for comminuted radial head fractures over the study period. Open reduction and internal fixation remains the most frequently used option, with the use of new fixation devices (eg, locking plates) increasing. The use of RHA more than doubled over the past 10 years while the number of radial head resections decreased. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.

Differences in 30-day outcomes between inpatient and outpatient total elbow arthroplasty (TEA). J Shoulder Elbow Surg 2020; 29:2640-2645. [PMID: 32619659 DOI: 10.1016/j.jse.2020.06.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 06/02/2020] [Accepted: 06/08/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND As the health care system in the United States shifts toward value-based care, there has been increased interest in performing total joint arthroplasty in the outpatient setting to optimize costs, outcomes, and patient satisfaction. Several studies have demonstrated success in performing ambulatory total knee and hip arthroplasty. The purpose of this study was to compare short-term outcomes and complications after total elbow arthroplasty (TEA) across the inpatient and outpatient operative settings. METHODS The American College of Surgeons National Quality Improvement Program database was queried to identify 575 patients undergoing primary TEA using the Current Procedural Terminology code 24363. Of this sample, 458 were inpatient and 117 were outpatient procedures. Propensity score matching using a 3:1 inpatient-to-outpatient ratio was performed to account for baseline differences in several variables-age, sex, body mass index class, American Society of Anesthesiologists class, and various comorbidities-between the inpatient and outpatient groups. After matching, the rates of various short-term outcomes and complications were compared between the inpatient and outpatient groups. RESULTS Inpatient TEA was associated with a higher rate of complications relative to outpatient TEA, including non-home discharge (14.9% vs. 7.5%, P = .05), unplanned hospital readmission (7.4% vs. 0.9%, P = .01), surgical complications (7.6% vs. 2.6%, P = .04), and medical complications (3.6% vs. 0.0%, P = .04). CONCLUSION Outpatient TEA has a lower short-term complication rate than inpatient TEA. Outpatient TEA should be considered for patients for whom such a discharge pathway is feasible. Future research should focus on risk stratification of patients and specific criteria for deciding when to pursue outpatient TEA.

Quantitative ultrahigh-molecular-weight polyethylene wear in total elbow retrievals. J Shoulder Elbow Surg 2020; 29:2364-2374.

Abstract
BACKGROUND The purpose of this study was to evaluate ultrahigh-molecular-weight polyethylene (UHMWPE) wear and damage from retrieved total elbow arthroplasty components and compare in vivo wear with wear produced in vitro. METHODS Explanted total elbow components were collected at revision surgery. UHMWPE damage was characterized visually, whereas penetration and wear were quantified using micro-computed tomography and gas pycnometry. Volumetric wear rates were compared with historical hip data, and wear data were compared with reported in vitro wear test data. RESULTS Humeral bushing damage primarily occurred in the form of burnishing, scratching, and pitting at the articular face in the region of contact with the ulnar component. Wear of the ulnar bushings was concentrated on the edge of the component at the point of contact with the axis pin. Pitting and embedded debris were dominant damage modes, in addition to burnishing and delamination. Backside wear was negligible. The median linear penetration rates of the lateral, medial, and ulnar bushings were 0.14 mm/yr (range, 0.01-0.78 mm/yr), 0.12 mm/yr (range, 0.03-0.55 mm/yr), and 0.11 mm/yr (range, 0.01-0.69 mm/yr), respectively. The volumetric wear rates of the lateral, medial, and ulnar bushings were 5.5 mm3/yr (range, 0.7-37.2 mm3/yr), 5.9 mm3/yr (range, 0.6-25.5 mm3/yr), and 5.5 mm3/yr (range, 1.2-51.2 mm3/yr), respectively. CONCLUSIONS The observed wear rates were similar to those reported in well-functioning total hip replacement patients with conventional UHMWPE bearings. We found limitations in reported in vitro testing resulting in wear that was not consistent with our retrieval data. We recommend further investigation to clinically validate in vitro simulation to provide appropriate loading protocols for elbow wear simulation.

Abstract
Total elbow arthroplasty is a common surgical procedure used in the management of advanced rheumatoid arthritis, posttraumatic arthritis, osteoarthritis, and unfixable fracture in elderly patients. Total elbow prostheses have evolved over the years and now include the linked, unlinked, and convertible types. However, long-term complications, including infection, aseptic loosening, instability, and periprosthetic fracture, remain a challenge. Here, we introduce each type of implant and evaluate clinical outcomes and complications by reviewing the previous literature.

Abstract
Total elbow arthroplasty design has evolved in recent decades. Indications for total elbow arthroplasty include advanced rheumatoid arthritis to osteoarthritis, post-traumatic arthritis, adverse sequelae of trauma, and unreconstructable acute fractures. This article summarizes the current evidence for total elbow arthroplasty, including the history of total elbow arthroplasty, an overview of the recent trends and designs, and current evidence-based outcomes. Outcomes are assessed for specific indications, namely rheumatoid arthritis, osteoarthritis, post-traumatic arthritis, acute trauma, and younger patients. Complication rates, reoperation rates, and survivorship of modern prostheses are discussed. Technical pearls and pitfalls are discussed for primary and revision cases.
