RESUMO

PURPOSE: To evaluate the extent to which experienced reviewers can accurately discern between AI-generated and original research abstracts published in the field of shoulder and elbow surgery and compare this to the performance of an AI-detection tool. METHODS: Twenty-five shoulder and elbow-related articles published in high-impact journals in 2023 were randomly selected. ChatGPT was prompted with only the abstract title to create an AI-generated version of each abstract. The resulting 50 abstracts were randomly distributed to and evaluated by 8 blinded peer reviewers with at least 5 years of experience. Reviewers were tasked with distinguishing between original and AI-generated text. A Likert scale assessed reviewer confidence for each interpretation and the primary reason guiding assessment of generated text was collected. AI output detector (0-100%) and plagiarism (0-100%) scores were evaluated using GPTZero. RESULTS: Reviewers correctly identified 62% of AI-generated abstracts and misclassified 38% of original abstracts as being AI-generated. GPTZero reported a significantly higher probability of AI output among generated abstracts (median 56%, IQR 51-77%) compared to original abstracts (median 10%, IQR 4-37%; p < 0.01). Generated abstracts scored significantly lower on the plagiarism detector (median 7%, IQR 5-14%) relative to original abstracts (median 82%, IQR 72-92%; p < 0.01). Correct identification of AI-generated abstracts was predominately attributed to the presence of unrealistic data/values. The primary reason for misidentifying original abstracts as AI was attributed to writing style. CONCLUSIONS: Experienced reviewers faced difficulties in distinguishing between human and AI-generated research content within shoulder and elbow surgery. The presence of unrealistic data facilitated correct identification of AI abstracts, whereas misidentification of original abstracts was often ascribed to writing style.

RESUMO

➤ Large language models are a subset of artificial intelligence. Large language models are powerful tools that excel in natural language text processing and generation.➤ There are many potential clinical, research, and educational applications of large language models in orthopaedics, but the development of these applications needs to be focused on patient safety and the maintenance of high standards.➤ There are numerous methodological, ethical, and regulatory concerns with regard to the use of large language models. Orthopaedic surgeons need to be aware of the controversies and advocate for an alignment of these models with patient and caregiver priorities.

RESUMO

Background: This study investigated the rate of acromial insufficiency fractures (AIF) in patients undergoing reverse shoulder arthroplasty (RSA) with concomitant distal clavicle excision (DCE). Methods: Patients who underwent primary RSA with DCE by a single surgeon from 2010 to 2021 were identified. Exclusion criteria included revision RSA, RSA for fracture, or cases utilizing an augmented baseplate or bone graft. AIF was defined as a radiographically proven acromion or scapular spine fracture. Pain without an identifiable fracture on imaging was defined as an acromial insufficiency reaction. Patient demographics, implant information, and radiograph measurements were compared between patients with and without acromial pathology. Results: One hundred and seventy-five patients were included. Mean age was 72.8 years, and 67% of patients were female. There were 3/174 acromial insufficiency fractures (1.7%). AIF occurred at a mean of 9.3 months after surgery. Twelve patients had insufficiency reactions (6.9%). Patients with acromial pathology were more likely to be female (p = .003) and have a diagnosis of osteoporosis (p = .047) and inflammatory arthritis (p = .049). There was no significant difference between groups in terms of other factors. Conclusion: The AIF rate in patients who underwent RSA with DCE was 1.7%. These findings suggest that DCE in the setting of RSA may have a protective role against AIF.

RESUMO

PURPOSE: To establish consensus statements on the diagnosis, nonoperative management, and labral repair for posterior shoulder instability. METHODS: A consensus process on the treatment of posterior shoulder instability was conducted, with 71 shoulder/sports surgeons from 12 countries participating on the basis of their level of expertise in the field. Experts were assigned to 1 of 6 working groups defined by specific subtopics within posterior shoulder instability. Consensus was defined as achieving 80% to 89% agreement, whereas strong consensus was defined as 90% to 99% agreement, and unanimous consensus was indicated by 100% agreement with a proposed statement. RESULTS: Unanimous agreement was reached on the indications for nonoperative management and labral repair, which include whether patients had primary or recurrent instability, with symptoms/functional limitations, and whether there was other underlying pathology, or patient's preference to avoid or delay surgery. In addition, there was unanimous agreement that recurrence rates can be diminished by attention to detail, appropriate indication and assessment of risk factors, recognition of abnormalities in glenohumeral morphology, careful capsulolabral debridement and reattachment, small anchors with inferior placement and multiple fixation points that create a bumper with the labrum, treatment of concomitant pathologies, and a well-defined rehabilitation protocol with strict postoperative immobilization. CONCLUSIONS: The study group achieved strong or unanimous consensus on 63% of statements related to the diagnosis, nonoperative treatment, and labrum repair for posterior shoulder instability. The statements that achieved unanimous consensus were the relative indications for nonoperative management, and the relative indications for labral repair, as well as the steps to minimize complications for labral repair. There was no consensus on whether an arthrogram is needed when performing advanced imaging, the role of corticosteroids/orthobiologics in nonoperative management, whether a posteroinferior portal is required. LEVEL OF EVIDENCE: Level V, expert opinion.

RESUMO

➤ No single test has demonstrated absolute accuracy for the diagnosis of periprosthetic joint infection (PJI).➤ Physicians rely on a combination of serological tests, synovial markers, and clinical findings plus clinical judgment to help to guide preoperative decision-making.➤ Several organizations have proposed criteria for the diagnosis of hip or knee PJI on which we now rely.➤ Given that shoulder arthroplasty has only recently become popular, it is possible that a shoulder-specific definition of PJI will be introduced in the coming years.➤ Although a number of serum and synovial markers have demonstrated high accuracy for the diagnosis of PJI of the hip and knee, further research is needed in order to identify markers that may be more suitable for the diagnosis of shoulder PJI and for the potential development and identification of specific serological tests as screening tools for PJI.

RESUMO

BACKGROUND: Physical therapy (PT) is a described first-line treatment option for glenohumeral arthritis, but its efficacy for treating this spectrum of disease is not well understood. The purpose of this study is to evaluate the opinions of expert providers-orthopedic surgeons and physical therapists-regarding the utility of PT in treating glenohumeral arthritis in different stages of radiographic severity. Our goal is to identify areas of interprofessional majority agreement as well as areas without agreement that warrant further investigation. METHODS: A 35-question survey was created and distributed via email to members of the American Shoulder and Elbow Surgeons and the American Society of Shoulder and Elbow Therapists, collecting information on demographics, professional experience, and the perceived benefit of PT for patients with different stages of glenohumeral arthritis based on radiographic severity. Survey responses were analyzed for inter-professional differences in distribution of answer choices as well as for majority agreement statements. Items with >50% agreement from a professional group were considered statements of majority agreement. RESULTS: One hundred and ninety surgeons and 39 physical therapists completed the survey. Surgeons and therapists demonstrated different distribution of answer choices in 25 of the 29 nondemographic related questions (86%). Surgeons and therapists reached the same majority statement in 8 items (28%) and reached disagreeing majority statements in 4 items (14%). They agreed on the benefits of PT for mild arthritis, the benefits of corticosteroid injections, the frequency of strengthening exercises, and that PT failure should not be required for surgical approval in patients with severe arthritis. They disagreed on the whether PT exacerbates symptoms in patients with moderate arthritis, and whether preoperative PT influences postoperative outcomes. CONCLUSION: Both surgeons and therapists agreed that PT may be less beneficial for patients with more advanced radiographic arthritis and that PT failure should not be required for insurance approval for surgical intervention in patients with severe glenohumeral arthritis. Further research is needed to determine the efficacy of PT for patients with moderate arthritis as well as the utility of preoperative PT for improving postoperative outcomes.

RESUMO

BACKGROUND: When treating chronic prosthetic joint infection after shoulder arthroplasty, removal of the implants and cement is typically pursued because they represent a potential nidus for infection. However, complete removal can increase morbidity and compromise bone stock that is important for achieving stable revision implants. The purpose of this study is to compare the rates of repeat infection after 2-stage revision for prosthetic joint infection in patients who have retained cement or hardware compared to those who had complete removal. MATERIALS AND METHODS: We retrospectively analyzed all two-stage revision total shoulder arthroplasties performed for infection at 2 institutions between 2011 and 2020 with minimum 2-year follow-up from completion of the two-stage revision. Patients were included if they met the International Consensus Meeting criteria for probable or definite infection. Postoperative radiographs after the first-stage of the revision consisting of prosthesis and cement removal and placement of an antibiotic spacer were reviewed to evaluate for retained cement or hardware. Repeat infection was defined as either ≥2 positive cultures at the time of second-stage revision with the same organism cultured during the first-stage revision or repeat surgery for infection after the two-stage revision in patients that again met the International Consensus Meeting criteria for probable or definite infection. The rate of repeat infection among patients with retained cement or hardware was compared to the rate of infection among patients without retained cement or hardware. RESULTS: Thirty-seven patients met inclusion criteria and were included in the analysis. Six (16%) patients had retained cement and 1 patient (3%) had 2 retained broken glenoid baseplate screws after first-stage revision. Of the 10 cases of recurrent infection, 1 case (10%) involved retained cement/hardware. Age at revision (60.9 ± 10.6 vs. 65.0 ± 9.6, P = .264), body mass index (33.4 ± 7.2 vs. 29.7 ± 7.3, P = .184), Charlson Comorbidity Index (2 (0-8) vs. 3 (0-6), P = .289), male sex (7 vs. 16, P = .420), and presence of diabetes (1 vs. 3, P = .709) were not associated with repeat infection. Retained cement or hardware was also not associated with a repeat risk of infection (1 vs. 6, odds ratio = 0.389, P = .374). DISCUSSION: We did not find an increased risk of repeat infection in patients with retained cement or hardware compared to those without. Therefore, we believe that surgeons should consider leaving cement or hardware that is difficult to remove and may lead to increased morbidity and future complications.

RESUMO

While several proximal humerus fractures treated nonsurgically reach satisfactory outcomes, some become symptomatic malunions or nonunions with pain and dysfunction. When joint-preserving options such as malunion or nonunion repair are not optimal because of poor remaining bone stock or glenohumeral arthritis, shoulder arthroplasty is a good option. Because of the semiconstrained design of reverse shoulder arthroplasty, it is effective at improving function when there is notable bony deformity or a torn rotator cuff. Clinical studies have demonstrated reliable outcomes, and a classification system exists that is helpful for predicting prognosis and complications. By understanding the associated pearls and pitfalls and with careful management of the tuberosities, reverse shoulder arthroplasty is a powerful tool for managing proximal humerus fracture sequelae.

RESUMO

PURPOSE: The purpose of this study was to establish consensus statements on glenoid bone-grafting, glenoid osteotomy, rehabilitation, return to play, and follow-up for posterior shoulder instability. METHODS: A consensus process on the treatment of posterior shoulder instability was conducted, with 71 shoulder/sports surgeons from 12 countries participating based on their level of expertise in the field. Experts were assigned to one of 6 working groups defined by specific subtopics within posterior shoulder instability. Consensus was defined as achieving 80-89% agreement, whereas strong consensus was defined as 90-99% agreement, and unanimous consensus was indicated by 100% agreement with a proposed statement. RESULTS: All of the statements relating to rehabilitation, return to play, and follow-up achieved consensus. There was unanimous consensus that the following criteria should be considered: restoration of strength, range of motion, proprioception, and sport-specific skills, with a lack of symptoms. There is no minimum time point required to return to play. Collision athletes and military athletes may take longer to return because of their higher risk for recurrent instability, and more caution should be exercised in clearing them to return to play, with elite athletes potentially having different considerations in returning to play. The relative indications for revision surgery are symptomatic apprehension, multiple recurrent instability episodes, further intra-articular pathologies, hardware failure, and pain. CONCLUSION: The study group achieved strong or unanimous consensus on 59% of statements. Unanimous consensus was reached regarding the criteria for return to play, collision/elite athletes having different considerations in return to play, indications for revision surgery, and imaging only required as routine for those with glenoid bone-grafting/osteotomies at subsequent follow-ups. There was no consensus on optimal fixation method for a glenoid bone-block, the relative indications for glenoid osteotomy, whether fluoroscopy is required or if the labrum should be concomitantly repaired. LEVEL OF EVIDENCE: Level V Expert Opinion.

RESUMO

Purpose: Minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) serve as metrics to gauge orthopedic treatment efficacy based on anchoring questions that do not account for a patient's satisfaction with their surgical outcome. This study evaluates if reaching MCID, SCB, or PASS values for American Shoulder and Elbow Surgeons score (ASES), Single Alpha Numeric Evaluation (SANE), Simple Shoulder Test (SST), and Visual Analog Score (VAS) for pain following arthroscopic rotator cuff repair (RCR) correlates with overall patient satisfaction. Methods: This was a single-institution, retrospective study of patients who underwent RCR from 2015 to 2019. Pre-operative and 2 year postoperative ASES, SANE, SST, and VAS scores were recorded. Patients underwent a survey to assess: (1) what is your overall satisfaction with your surgical outcome? (scale 1 to 10); (2) if you could go back in time, would you undergo this operation again? (yes/no); (3) for the same condition, would you recommend this operation to a friend or family member? (yes/no). Spearman correlation coefficients were run to assess relationship between reaching MCID, SCB, or PASS and satisfaction. Results: Ninety-two patients were included. Mean preoperative ASES was 51.1 ± 16.9, SANE was 43.3 ± 20.9, SST was 5.4 ± 2.9, and VAS was 4.6 ± 2.1. Mean 2 year ASES was 83.9 ± 18.5, SANE was 81.7 ± 27.0, SST was 9.8 ± 3.2, and VAS was 1.4 ± 1.9. Mean patient satisfaction was 9.0 ± 1.9; 89 (96.7%) patients would undergo surgery again and recommend surgery. Correlation for reaching PASS for SANE and satisfaction was moderate. Correlation coefficients were very weak for all other outcome metrics. Conclusions: Reaching MCID, SCB, and PASS in ASES, SANE, SST, or VAS following RCR did not correlate with a patient's overall satisfaction or willingness to undergo surgery again or recommend surgery. Further investigation into the statistical credibility and overall clinical value of MCID, SCB, and PASS is necessary.

RESUMO

BACKGROUND: Orthopedic residency and fellowship applicants with a strong research record are highly valued for their potential in continuing academic excellence. Despite this, the association between research productivity during training and future academic productivity as an attending orthopedic surgeon is not well-established. We assess the effects of research output during different periods of surgical training as well as residency location on long-term academic productivity as an attending shoulder and elbow surgeon. METHODS: A search of the 2022-2023 American Shoulder and Elbow Surgeons Fellowship Directory was conducted to identify a list of orthopedic shoulder and elbow fellowship faculty members. Each surgeon's residency, fellowship and current institution of practice were determined and stratified by geographic location. Total publication counts acquired before residency, during residency, during fellowship, and after fellowship were collected for each faculty member. Attending publication rates and H-indices were calculated. A multivariate linear regression model was created, and significance was set at a P value <.05. RESULTS: A total of 149 shoulder and elbow fellowship faculty members representing 34 fellowship programs were identified. The average number of total publications per surgeon was 88.8 ± 102. The average attending publication rate was 5.29 ± 6.89 publications per year. The average H-index for included surgeons was 27.8 ± 24.4. The number of publications acquired before residency (ß = 0.293; P < .001), during residency (ß = 0.110; P = .025) and during fellowship (ß = 0.593; P < .001) were significantly associated with an increased attending publication rate, but no association was observed with the H-index [before residency (ß = -0.221; P = .574), during residency (ß = 0.045; P = .866), during fellowship (ß = 0.198; P = .678)]. There were no significant differences in total publication count (P = .397), attending publication rate (P = .237), or H-index (P = .364) based on location of residency training. DISCUSSION: Research output before and during surgical training is predictive of continued academic productivity as a shoulder and elbow surgeon. In particular, greater productivity during surgical fellowship was most predictive of academic output as an attending. While long-term academic productivity does not seem to be influenced by the geographic location of residency training, attending surgeons practicing in the Midwest had significantly greater total publication counts and H-indices but similar annual publication rates.

RESUMO

BACKGROUND: Many patients who undergo shoulder arthroplasty (SA) have had at least 1 nonarthroplasty shoulder surgery before the surgery. There is conflicting evidence regarding the effects of previous shoulder surgery on the outcome of SA. A systematic review was conducted to compare functional outcomes and complications between SA patients with and without prior non-SA surgery on the ipsilateral shoulder. METHODS: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searched MEDLINE/PubMed, Embase, Scopus, and Web of Science comprehensively from inception to January 2023. Based on 9,279 records reviewed, 26 comparative studies were included in the meta-analysis consisting of 5,431 shoulders with prior nonarthroplasty procedures (cases) and 55,144 shoulders without previous surgery (controls). Variables such as functional scores, complications, and range of motion were compared between cases and controls using Review Manager Software. In addition, subgroup analysis was conducted based on prior surgery type (rotator cuff repair [RCR], open reduction and internal fixation [ORIF], soft tissue repairs, and not specified) and type of SA (hemiarthroplasty, anatomical total shoulder arthroplasty, and reverse total shoulder arthroplasty [RTSA]). The results were presented as odds ratios (ORs) or standardized mean differences (SMDs). RESULTS: Except for a higher rate of periprosthetic joint infection (PJI) in patients who had undergone previous arthroscopic surgery (OR, 2.58; 95% confidence interval [CI], 1.66-4.01; p < 0.01), a higher rate of complications was only observed in patients with previous ORIF. These complications included aseptic loosening (OR, 3.43; 95% CI, 2.14-5.50; p < 0.01), shoulder dislocation (OR, 2.25; 95% CI, 1.05-4.84; p = 0.04), overall complication (OR, 3.95; 95% CI, 2.38-6.55; p < 0.01), and revision (OR, 2.52; 95% CI, 1.28-4.97; p = 0.01). Patients with a history of previous surgery demonstrated inferior functional outcomes in comparison with the control group, including American Shoulder and Elbow Surgeons (SMD, -0.39; 95% CI, -0.51 to -0.27; p < 0.01; I2 = 36%), Constant-Murley score (SMD, -0.34; 95% CI, -0.44 to -0.24; p < 0.01; I2 = 0%), abduction (SMD, -0.26; 95% CI, -0.45 to -0.08; p = 0.01; I2 = 54%), and flexion (SMD, -0.33; 95% CI, -0.46 to -0.21; p < 0.01; I2 = 40%). Subgroup analysis by previous type of surgery was not possible regarding functional outcomes. CONCLUSION: Patients who have had prior fracture surgery are at a higher risk of complications, reoperations, and revisions after SA than controls. The normal shoulder anatomy may be disrupted by prior surgery, which makes arthroplasty technically challenging, particularly when it comes to soft tissue balance. On the other hand, RCR before SA did not negatively affect clinical outcomes after RTSA and did not have a higher rate of overall complications (except PJI). LEVEL OF EVIDENCE: Level III (Treatment Studies). See Instructions for Authors for a complete description of levels of evidence.

RESUMO

BACKGROUND: Aseptic humeral stem loosening is an uncommon complication of shoulder arthroplasty, and its presence has been considered a highly specific predictor of prosthetic joint infection (PJI). Literature on aseptic humeral stem loosening is sparse. The primary purpose of this study was to determine the rate of aseptic humeral loosening in revision shoulder arthroplasty. Secondarily, we sought to identify predictors of septic and aseptic humeral loosening. METHODS: Our institutional revision shoulder arthroplasty database was reviewed. Inclusion criteria were patients with humeral stem loosening as indicated in the operative report. Patient demographics, index surgery and indication, revision surgery and indication, and operative data were recorded. Charts were manually reviewed, and PJI scores were calculated using the International Consensus Meeting scoring criteria. International Consensus Meeting classifications of PJI "unlikely" and "possible" were considered aseptic, and PJI "probable" and "definite" were considered septic. Statistical analysis was performed to determine associations between the abovementioned variables and aseptic humeral loosening. RESULTS: Forty-six patients with 48 shoulders were included in our analysis. Ten cases (21%) were classified as definite PJI, 13 cases (27%) were classified as probable PJI, 4 cases (8%) were classified as possible PJI, and 21 cases (44%) were classified as PJI unlikely. On analysis of stem design, there were no statistically significant associations with aseptic loosening; although, a lack of proximal porous ingrowth surface trended toward higher rates of aseptic loosening in all patients and in anatomic total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) subgroup analyses. In the index RTSA subgroup, aseptic loosening was associated with female sex (P = .005). Seventeen of 39 shoulders (44%) that underwent either index ATSA or RTSA demonstrated concomitant glenoid loosening. The absence of glenoid loosening was associated with aseptic humeral loosening in index ATSA and RTSA (P < .001). CONCLUSION: Fifty-two % of revision shoulder arthroplasty cases with humeral loosening performed at our institution were aseptic. There appear to be distinct demographic and radiographic factors that are more commonly associated with aseptic as opposed to septic humeral loosening. Our data demonstrate that demographic predictors of aseptic loosening of RTSA include female sex. The absence of glenoid component loosening is associated with aseptic humeral loosening and concomitant glenoid loosening is associated with septic humeral loosening. Understanding of these factors can guide the preoperative index of suspicion for PJI in the setting of humeral stem loosening.

RESUMO

Objectives: Arthroscopic Latarjet for glenohumeral stabilization has emerged as an alternative to the open approach; however, the evidence to date has questioned if this technique delivers improved outcomes. This analysis provides an assessment of the cost and utility associated with arthroscopic versus open Latarjet. Methods: The cost-effectiveness of Latarjet stabilization was modeled over a ten-year period. Institutional cases were reviewed for equipment utilization. Cost data from ambulatory surgical centers was obtained for each piece of equipment used intraoperatively. Based upon prior analyses, the operating room cost was assigned a value of $36.14 per minute. To determine effectiveness, a utility score was derived based upon prior analysis of shoulder stabilization using the EuroQol (EQ) 5D. For reoperations, a utility score of 0.01 was assigned for a single year for revision surgeries for instability and 0.5 for minor procedures. Probability of surgical outcomes and operative time for arthroscopic and open Latarjet were taken from prior studies comparing outcomes of these procedures. Decision-tree analysis utilizing these values was performed. Results: Based upon equipment and operating room costs, arthroscopic Latarjet was found to cost $2,796.87 more than the equivalent open procedure. Analysis of the utility of these procedures were 1.330 and 1.338 quality adjusted life years obtained over the modeled period for arthroscopic versus open Latarjet, respectively. For arthroscopic Latarjet to be cost-equivalent to open Latarjet, surgical time would need to be reduced to 41.5 minutes or the surgical equipment would need to be provided at no expense, while maintaining the same success rates. Conclusion: With nearly identical utility scores favoring open surgery, the added cost associated with arthroscopic Latarjet cannot be supported with available cost and utility data. To provide value, additional benefits such as decreased post-operative narcotic utilization, decreased blood loss, or lower complications of the arthroscopic approach must be demonstrated.

RESUMO

Background: Previous reports found that 40% of randomized controlled trials (RCTs) published in The Journal of Bone & Joint Surgery (JBJS) from 1988 to 2000 and 47% of those published from 2001 to 2013 were of high quality. The purpose of this study was to assess the quality of RCTs published from 2014 to 2022 in JBJS and to compare these findings with those of prior analyses in order to identify trends over time and areas for continued improvement. Methods: PubMed was searched for the term "randomized controlled trial" to identify studies published in JBJS from 2014 to 2022. Each included RCT was evaluated with use of the Detsky score and a risk-of-bias assessment modified from the Cochrane tool. These evaluations were then compared with previous evaluations of RCTs from the 1988 to 2000 and 2001 to 2013 periods with use of independent-sample t tests. A transformed Detsky score of >75% and a modified risk-of-bias score of ≥8 were defined as being indicative of high quality. Results: A total of 218 RCTs were published in JBJS from 2014 to 2022. An a priori sample size was calculated in 183 studies (83.9%). A total of 152 (83.1%) of the 183 studies enrolled the calculated number of patients, of which 126 (82.9%) maintained an adequate number at the time of final follow-up. Most RCTs were conducted at a single center (146 of 218; 67%), evaluated a surgical intervention (162 of 218; 74%), and reported positive results (142 of 218; 65%). The mean transformed Detsky score was 85% ± 10% (95% confidence interval, 83.7% to 86.3%), with 82% of trials (179 of 218) scored as high quality. The mean transformed Detsky score from 2014 to 2022 was higher than that from 1988 to 2000 and that from 2001 to 2013 (85% versus 76% and 68%, respectively; p < 0.001). The mean modified risk-of-bias score was 7 ± 1, with 42% of trials (92 of 218) scored as high quality. RCTs published from 2014 to 2022 had a higher mean modified risk-of-bias score than those published from 2001 to 2013 (7 ± 1 versus 6 ± 1; p < 0.001). Compared with the 2001 to 2013 and 2014 to 2022 periods, the 1988 to 2000 period had a greater proportion of trials that reported positive results (51% and 65% versus 82%, respectively; p < 0.001) and that included data from multiple centers (31% and 33% versus 67%; p < 0.001). Conclusions: The quality of RCTs published in JBJS from 2014 to 2022 has improved from that reported previously, as demonstrated by the increases in the modified risk-of-bias score and transformed Detsky score from prior periods. This may be the result of journal policies such as the requirements of CONSORT adherence and prospective trial registration. Investigators should focus on improving the clarity of reporting, limiting attrition bias, and making efforts to blind support staff in order to increase the quality of future RCTs. Clinical Relevance: Improving the quality of RCTs is crucial given their potential to influence current clinical practice.

RESUMO

BACKGROUND: Despite 2-stage revision being a common treatment for elbow prosthetic joint infection (PJI), failure rates are high. The purpose of this study was to report on a single institution's experience with 2-stage revisions for elbow PJI and determine risk factors for failed eradication of infection. The secondary purpose was to determine risk factors for needing allograft bone at the second stage of revision in the setting of compromised bone stock. METHODS: We retrospectively analyzed all 2-stage revision total elbow arthroplasties (TEAs) performed for infection at a single institution between 2006 and 2020. Data collected included demographics and treatment course prior to, during, and after 2-stage revision. Radiographs obtained after explantation and operative reports were reviewed to evaluate for partial component retention and incomplete cement removal. The primary outcome was failed eradication of infection, defined as the need for repeat surgery to treat infection after the second-stage revision. The secondary outcome was the use of allograft for compromised bone stock during the second-stage revision. Risk factors for both outcomes were determined. RESULTS: Nineteen patients were included. Seven patients (37%) had either the humeral or ulnar component retained during the first stage, and 10 (53%) had incomplete removal of cement in either the humerus or ulna. Nine patients (47%) had allograft strut used during reimplantation and reconstruction. Nine patients (47%) failed to eradicate the infection after 2-stage revision. Demographic data were similar between the repeat-infection and nonrepeat-infection groups. Six patients (60%) with retained cement failed compared with 3 patients (33%) with full cement removal (P = .370). Two patients (29%) with a retained component failed compared to 7 patients (58%) with full component removal (P = .350). Allograft was used less frequently when a well-fixed component or cement was retained, with no patients with a retained component needing allograft compared to 9 with complete component removal (P = .003). Three patients (30%) with retained cement needed allograft, compared with 6 patients (67%) who had complete cement removal (P = .179). CONCLUSION: Nearly half of the patients failed to eradicate infection after 2-stage revision. The data did not demonstrate a clear association between retained cement or implants and risk of recurrent infection. Allograft was used less frequently when a component and cement were retained, possibly serving as a proxy for decreased bone loss during the first stage of revision. Therefore, the unclear benefit of removing well-fixed components and cement need to be carefully considered as it likely leads to compromised bone stock that complicates the second stage of revision.

RESUMO

BACKGROUND: Nonsurgical management of chronic, degenerative rotator cuff tears (RCTs) can be an effective treatment strategy, but there is limited evidence to support conservative treatment of acute, traumatic RCTs. The objective of this study was to assess clinical outcomes and predictors of treatment success in patients with traumatic RCTs who elected for initial nonoperative treatment. METHODS: Patients from a single institution were retrospectively identified using diagnostic codes for traumatic RCTs followed by confirmed initial treatment with ≥2 months of physical therapy. The exclusion criteria included surgery within 2 months of injury and greater than grade I fatty infiltration on magnetic resonance imaging. At minimum 2-year follow-up, patients were contacted by telephone to collect interval surgical history and standardized patient-reported outcomes. Physical therapy was considered to have failed in all those who underwent surgical treatment and those with satisfaction ratings of "moderately dissatisfied" or "very dissatisfied." RESULTS: Follow-up outcomes were obtained in 40 of 49 patients (82%), with an average follow-up time of 4.2 years. Of the RCTs, 9 (22%) were small (<1 cm), 22 (54%) were medium (>1 cm to <3 cm), and 9 (22%) were large (>3 cm to <5 cm). Grade I fatty infiltration was seen on 25% of magnetic resonance imaging scans (n = 10). Rotator cuff repair was performed in 18 patients (45%) following an average of 6 months of nonoperative treatment (range, 3-12 months). Nonoperative treatment was determined to have failed in 23 of 40 patients (58%) in total. Conservative management was more likely to fail in patients with multiple tendons torn (P = .014). Tear size and retraction were not significantly different between patients who underwent surgery and those who did not. Patients who underwent surgical management had an 83% satisfaction rate at final follow-up compared with a 55% satisfaction rate for patients who did not undergo surgery (P = .054). There was no statistically significant difference in the American Shoulder and Elbow Surgeons score or visual analog scale score between these groups. Although patients who underwent surgery had a higher mean Single Alpha Numeric Evaluation score (86.3 vs. 75.1, P = .041), this difference was below the previously established minimal clinically important difference. CONCLUSION: Nonoperative treatment remains a viable option for certain patients with traumatic RCTs; however, the results of our study demonstrate a considerable early failure rate. This study further supports historical literature demonstrating reliably successful outcomes with surgical treatment of acute, traumatic RCTs.

RESUMO

BACKGROUND: Hyperglycemia is a known risk factor for tendon degeneration due to oxidative stresses from production of advanced glycosylation end products. In patients with diabetes mellitus (DM), analysis of glycated hemoglobin (HbA1c) provides a 3-month window into a patient's glucose control. No guidelines exist for ideal preoperative HbA1c and glucose control prior to arthroscopic rotator cuff repair. This study evaluated if a critical HbA1c level is associated with reoperation following arthroscopic rotator cuff repair. METHODS: We retrospectively evaluated patients with DM who underwent primary arthroscopic rotator cuff repair from January 2014 to December 2018 at a single institution. Patients required a preoperative HbA1c within 3 months of surgery. Medical records were queried to evaluate for reoperation and identify the subsequent procedures performed. Univariate statistical analysis was performed to assess factors associated with reoperation (P < .05 considered significant). Threshold, area under the curve (AUC), analysis was performed to assess if a critical HbA1c value was associated with reoperation. RESULTS: A total of 402 patients met inclusion criteria. Patients had an average age of 65.5 years (range 40-89) at time of surgery; 244 (60.6%) patients were male; and average body mass index was 32.96 ± 5.81. Mean HbA1c was 7.36 (range 5.2-12). Thirty-three patients (8.2%) underwent subsequent reoperation. Six patients (1.5%) underwent capsular release and lysis of adhesions, 20 patients (5.0%) underwent a revision rotator cuff surgery, combination revision rotator cuff repair and lysis of adhesions, graft-augmented revision repair, or superior capsular reconstruction, and 7 patients (1.7%) underwent revision to reverse shoulder arthroplasty (1.7%). There were no cases of reoperation for infection. On AUC analysis, no critical HbA1c value was identified to predispose to reoperation. Interestingly, elevated preoperative American Society of Anesthesiologists (ASA) physical status classification score (2.8 vs. 2.28, P = .001) was associated with a higher reoperation rate. DISCUSSION: In patients with DM, preoperative HbA1c is not a predictive factor for surgical failure requiring reoperation. Stable glycemic control is important to a patient's overall health and may play a role in minimizing postoperative medical complications, but an elevated preoperative HbA1c should not be a strict surgical contraindication for arthroscopic rotator cuff repair. In patients with DM, an elevated ASA score is associated with an increased rate of subsequent reoperation; diabetic patients should be counseled accordingly.

RESUMO

BACKGROUND: Upper-extremity fractures (UEFs) account for a large proportion of bone fractures and are costly to both health and the economy. The fracture burden in the Middle East and North Africa (MENA) is influenced by the region's diverse cultural, economic, and political status. This study examined UEF epidemiology and causes across the MENA region and within the 21 MENA countries as categorized by the Global Burden of Disease (GBD) data set. METHODS: On the basis of GBD data, this study evaluated the epidemiology of UEFs from 1990 to 2019. The causes of injuries, incidence, number of years of healthy life lost due to disability (YLD), and their association with the Socio-demographic Index (SDI) were obtained and calculated for males and females in all age groups. RESULTS: From 1990 to 2019, the age-standardized incidence rate (ASIR) of UEFs in the MENA region increased by 2.33%, to 1,086.39 per 100,000 people, and the YLD rate increased 15.69%, to 9.17 per 100,000, opposing the global decreasing trends. Fractures of the radius and/or ulna had the highest ASIR (505.32 per 100,000) of all UEF types in 2019. The clavicle, scapula, and humerus had the highest increasing trend among the fracture sites. In 2019, Saudi Arabia had the highest ASIR of UEFs (2,296.93 per 100,000). Afghanistan had the highest age-standardized YLD rate due to UEFs (19.6 per 100,000) in 2019, with Syria (153.32%) and Iran (37.04%) experiencing the greatest increase and decrease, respectively, from 1990 to 2019. Falling was the leading cause of UEFs, accounting for 45.05% of incidence and 41.19% of YLD overall. CONCLUSIONS: Contrary to global trends, UEFs increased in the MENA region during the study period. Countries with higher fracture incidence and YLD should consider preventive and rehabilitation strategies.

RESUMO

Rotator cuff repair is commonly performed, and stiffness represents one of the most common complications. Unique characteristics of postoperative stiffness, including its natural history and pathoanatomy, differentiate it from other etiologies of shoulder stiffness. Patient risk factors that have been associated with postoperative stiffness should be reviewed to better help clinicians tailor their presurgical risk assessment. Although stiffness in this setting has clinical consequences for patients' postoperative shoulder function, it is important to discuss the important implications of stiffness as it relates to rotator cuff healing. Multiple strategies have been proposed to decrease the incidence of postoperative stiffness. There is evidence to support these preventive strategies, and it has led to author recommendations for treatment of refractory cases and prevention.
