Adjunctive Dorsal Spanning Plate Fixation in the Stabilization of Perilunate Dislocations.

PURPOSE: To compare the biomechanical properties of adjunctive dorsal spanning plate (DSP) fixation with traditional K-wire fixation of perilunate dislocations in a cadaveric model. METHODS: Fourteen fresh-frozen cadaveric wrists underwent simulated perilunate injury. The specimens were randomly allocated to either K-wire fixation versus K-wire and DSP fixation. Scapholunate (SL) ligament repair was performed in all specimens. The constructs were tested using a robot cyclically and to failure. Fluoroscopic images were obtained of the specimens prior to simulated injury, after fixation, after 10 and 100 loading cycles, and at construct failure. Differences in carpal alignment parameters (SL interval, SL angle, lunotriquetral interval, and capitolunate angle) and load to failure were recorded. RESULTS: There were no statistically significant differences between the two group's carpal alignment parameters after fixation. Specimens fixated with K-wires and DSP required significantly higher loads to achieve construct failure. The only significant difference between the two groups' carpal alignment parameters was SL interval change at failure. CONCLUSIONS: Compared with K-wire fixation alone, adjunctive DSP fixation resulted in significantly increased loads to failure and decreased change in SL interval at the time of failure. CLINICAL RELEVANCE: Adjunctive DSP may be a useful technique in the polytraumatized patient in whom providing back a weight-bearing extremity may be advantageous in the rehabilitation process.

Experimenting With the New Frontier: Artificial Intelligence-Powered Chat Bots in Hand Surgery.

Background: Increased utilization of artificial intelligence (AI)-driven search and large language models by the lay and medical community requires us to evaluate the accuracy of AI responses to common hand surgery questions. We hypothesized that the answers to most hand surgery questions posed to an AI large language model would be correct. Methods: Using the topics covered in Green's Operative Hand Surgery 8th Edition as a guide, 56 hand surgery questions were compiled and posed to ChatGPT (OpenAI, San Francisco, CA). Two attending hand surgeons then independently reviewed ChatGPT's answers for response accuracy, completeness, and usefulness. A Cohen's kappa analysis was performed to assess interrater agreement. Results: An average of 45 of the 56 questions posed to ChatGPT were deemed correct (80%), 39 responses were deemed useful (70%), and 32 responses were deemed complete (57%) by the reviewers. Kappa analysis demonstrated "fair to moderate" agreement between the two raters. Reviewers disagreed on 11 questions regarding correctness, 16 questions regarding usefulness, and 19 questions regarding completeness. Conclusions: Large language models have the potential to both positively and negatively impact patient perceptions and guide referral patterns based on the accuracy, completeness, and usefulness of their responses. While most responses fit these criteria, more precise responses are needed to ensure patient safety and avoid misinformation. Individual hand surgeons and surgical societies must understand these technologies and interface with the companies developing them to provide our patients with the best possible care.

Reverse Hemi-Hamate Autograft for Volar Proximal Interphalangeal Joint Fracture-Dislocations.

Volar proximal interphalangeal joint fracture-dislocations are rare injuries. Treatment is challenging when they are not identified acutely, with poor outcomes reported. We report a surgical technique to treat chronic volar proximal interphalangeal joint fracture-dislocations: a reverse hemi-hamate autograft.

The Evidence Basis for Learning Theory and Technology in Surgical Skills Training.

Orthopaedic trainees face a complex and challenging training environment that is currently becoming more competency driven. Associated with these changes are an increasing introduction and use of a variety of technologically driven surgical training augments. Although these new learning resources can positively transform the educational environment, they must be used appropriately by both learners and educators. To aid in this, we review learning theories because they apply to surgical skills training and highlight recent surgical training evidence that demonstrates how technology use can be optimized to promote surgical learning, with an emphasis on procedural learning theory and cognitive load theory. Specifically, we review the evidence demonstrating the importance of targeting technology to a learner's experience level and methods to optimize cognitive load by managing intrinsic load, minimizing extraneous load, and maximizing germane load.

Automating Patient-Reported Outcome Measures Following Hand Surgery.

PURPOSE: The purpose of this study was to assess the overall response rate of patients receiving electronic patient-reported outcome measures (ePROMs) following hand surgery and to determine the patient characteristics associated with responding. METHODS: A Health Insurance Portability and Accountability Act-compliant, web-based system was developed to automatically distribute ePROMs to patients undergoing hand surgery at five institutions with 22 surgeons. Patients who were at least 18 years old were eligible. The PROMs used were the visual analog scale (VAS) for pain and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH). After surgery, ePROMs along with a satisfaction questionnaire were electronically sent three, six, 12, 24, and 52 weeks after surgery. RESULTS: A total of 6458 patients were eligible. Of these, 80% were enrolled voluntarily. Among these, 70% completed ePROMs for at least one postoperative time point, whereas 30% did not complete any. Among responders, 28% completed all five time points, whereas 72% completed four or fewer time points. Incomplete responders were more likely to be insured by workers' compensation when compared to complete responders. Incomplete responders exhibited higher baseline QuickDASH scores and similar baseline VAS compared to complete responders. During the follow-up, incomplete responders demonstrated worse VAS and QuickDASH scores at all time points. Finally, in comparison with complete responders, incomplete responders were less likely to be satisfied with their surgery at all time points. CONCLUSIONS: This study demonstrates that automated email-based ePROM systems may be an effective method for survey distribution. Particularly for simple, outpatient surgeries, this study illustrates the potential for clinical use of the data obtained from these systems. CLINICAL RELEVANCE: Patient-reported outcome measures continue to have an expanding role in health care with the rise of valued-based systems. Electronic PROMs are a relatively unexplored medium that may offer a viable alternative to more effectively collecting these valuable patient metrics.

Short-Term Patient Outcomes after Placement of an Internal Joint Stabilizer for Terrible Triad Injuries: A Multicenter Study.

PURPOSE: The purpose of this study was to assess the functional and patient-reported outcomes after the use of the internal joint stabilizer (IJS) for unstable terrible triad injuries. Specifically, we sought to determine our complication rate and the impact of complications on patient outcomes. METHODS: We identified all patients who had an IJS placed as a supplemental fixation for a terrible triad injury at two urban, level 1 academic medical centers. We reviewed these patients' charts for demographic information, complication profiles, postoperative range of motion (ROM), and pain-level data. We also collected the QuickDASH and Patient-Rated Elbow Evaluation (PREE) scores. Descriptive statistics were reported. Final visit data were compared between patients who returned to the OR for a complication and those who did not. RESULTS: From 2018 to 2020, 29 patients had an IJS placed for a terrible triad injury. The median final follow-up was 6.3 months after surgery (IQR: 6.2 months). There were 38 complications in 19 patients (65.5%) that required 12 patients to return to the OR (41.3%) for procedures beyond simple IJS removal. There were no significant differences in the ROM between patients who returned to the OR for a complication and those who did not. QuickDASH and PREE scores were greater (indicating more disability) in patients who had a complication that required a secondary surgical procedure. CONCLUSIONS: Patients who receive an IJS incur a high rate of complications. When patients sustain complications that require secondary surgeries, their ultimate functional outcome scores worsen. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

An Assessment of Upper-Extremity Surgical Technique Videos and Their Relationship With Procedural Learning Theory.

PURPOSE: Our purpose was to ascertain how well award-winning and highly viewed upper-extremity surgical videos meet the needs of users and adhere to procedural learning theory. We hypothesized that upper-extremity videos hosted on academic society websites meet user needs better than upper-extremity videos hosted on a commercial website. METHODS: Twenty-five upper-extremity videos were evaluated by 3 reviewers. A standardized scoring sheet was used to assess each video's content, production quality, and adequacy. Video lengths were compared. The inclusion frequencies of specific content categories, the adequacy of content, and meeting certain production standards, all of which assess consistency with procedural learning theory, were reported, stratified by video host. Associations between the video host and video content, production quality, and adequacy were assessed. RESULTS: The median lengths of academically hosted and commercially hosted videos were similar. Regardless of the video host, no video contained information in all content categories. Sixty percent of the scored categories were present in less than 75% of evaluated videos. Academically hosted videos contained scored content more frequently than commercially hosted videos in 68.4% of categories. There were significant associations between academic hosts and inclusion of a case presentation, surgical indications, outcomes literature, a preoperative examination, follow-up visit intervals, and alternative surgical techniques. Overall, academically hosted videos had a higher percentage of adequate content categories compared with commercially hosted videos. CONCLUSIONS: Videos on academic websites more consistently meet users' content needs and production expectations, as informed by procedural learning theory, while having higher rates of adequate content compared with videos on commercial websites. CLINICAL RELEVANCE: While academically hosted videos appear to more consistently adhere to the tenets of procedural learning theory, opportunity exists for video creators to more consistently apply procedural learning theory, allowing for the creation of even more educationally beneficial online surgical videos.

Patient Likelihood to Repeat Surgery After Highly "Successful" Hand Procedures.

BACKGROUND: Outcomes for routine hand procedures, such as carpal tunnel release, trigger finger release, and first dorsal compartment release, are typically reported as "highly successful" with "infrequent complications" based on classic literature. No contemporary study has utilized a large prospective registry to assess patient willingness to repeat surgery. We utilized a prospective hand registry to evaluate the proportion of patients that would repeat surgery after common hand procedures. METHODS: We utilized a prospective, hand surgery registry to collect postoperative patient likelihood to repeat surgery in patients undergoing surgery for 9 common hand procedures. All measures were reported at 12, 24, or 52 weeks. We analyzed the percentage of patients that would repeat the procedure for all diagnoses, as well as stratified by the most common 9 isolated diagnoses. RESULTS: At the time of analysis, 1905 patients met our inclusion criteria. The average percentage of patients across all procedures that would repeat surgery was 81.6%. When stratified by the most common 9 diagnoses the percentage of patients that would repeat surgery ranged from 51.9% (ulnar nerve surgery at the elbow) up to 87.5% (endoscopic carpal tunnel release). CONCLUSIONS: After undergoing routine hand procedures, a significant percentage of patients would choose not to repeat surgery. Hand surgeons can do better in setting clear and realistic preoperative expectations when counseling patients prior to even routine hand surgeries.

Carpometacarpal Arthrodesis: Indications and Techniques.

Trapeziometacarpal arthrodesis is a beneficial surgery for young and higher-demand patients who have trapeziometacarpal arthritis. Surgical techniques can vary, but certain aspects of the surgery are critical, including bony preparation and positioning of the thumb in space. Reported outcomes are generally favorable, although the quality of evidence is poor. There are no comparison studies assessing different arthrodesis techniques, and only a few comparing arthrodesis to the trapeziometacarpal arthroplasty procedures. Most published results are case series with retrospectively collected data.

Casting Position for Distal Radius Fractures Changes Radiocarpal Joint Forces: A Cadaveric Study.

PURPOSE: Nonsurgical distal radius fracture treatment requires immobilization and classical teaching suggests varying cast positions. We investigated the effect of cast position on the force and pressure experienced by the articular cartilage in the scaphoid and lunate fossae. METHODS: Ten fresh-frozen cadaveric specimens were used. A standardized extra-articular distal radius fracture was made. Force sensors were affixed to the articular cartilage of the scaphoid and lunate fossae. Baseline data were obtained. Specimens were then placed into a short arm cast with the wrist either neutrally aligned or flexed and ulnarly deviated (FUD). Specimens had a standard load applied, and a force profile was obtained. The cast was removed and the other cast type was placed and measurements were repeated. Overall force and pressure values were compared between baseline data and the 2 cast types. Additionally, differences in volar and dorsal scaphoid and lunate fossa forces and pressures were compared pairwise within the 2 cast types. The relative force and pressure values across cast types were also compared. RESULTS: Both cast types significantly reduced the median force and pressure experienced by the radiocarpal joint compared with no cast. In the FUD cast, the volar and dorsal lunate fossa experienced significantly greater force, and the dorsal lunate fossa experienced significantly greater pressure compared with the dorsal scaphoid fossa. There were no differences for any fossae in the neutral cast. When comparing between casts, the volar lunate fossa experienced a significantly greater relative force in the FUD cast compared with the neutral cast. CONCLUSIONS: Casting a distal radius fracture decreases the forces and pressures in the radiocarpal joint. Placing the wrist in a FUD position results in greater forces and pressures on the lunate fossa compared with the scaphoid fossa. CLINICAL RELEVANCE: When immobilization is needed, we advocate for the placement of patients in a relatively neutral short-arm cast with minimal FUD to avoid this increased pressure.

Automated Reporting of Patient Outcomes in Hand Surgery: A Pilot Study.

BACKGROUND: Obtaining patient-reported outcomes (PROs) is becoming a standard component of patient care. For nonacademic practices, this can be challenging. From this perspective, we designed a nearly autonomous patient outcomes reporting system. We then conducted a prospective, cohort pilot study to assess the efficacy of the system. METHODS: We created an automated system to gather PROs. All operative patients for 4 surgeons in an upper-extremity private practice were asked to participate. These patients completed the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaires preoperatively and received follow-up e-mails requesting patients to complete additional QuickDASH questionnaires at 3, 6, and 12 weeks postoperatively and to complete a 13-week postoperative satisfaction survey. Response rates and satisfaction levels are reported with descriptive statistics. RESULTS: Sixty-two percent of participants completed the 3-week assessment, 55% completed the 6-week assessment, and 43% completed the 12-week assessment. Overall, 35% of patients completed all questionnaires, and 73% completed at least 1 postoperative assessment. The collection of follow-up questionnaires required no additional time from the clinical staff, surgeon, or a research associate. CONCLUSIONS: Automated e-mail assessments can collect reliable clinical data, with minimal surgeon or staff intervention required to administer and collect data, minimizing the financial cost. For nonacademic practices, without access to additional research resources, such a system is feasible. Further improvements in communication with patients could increase response rates.

The Orthopaedic Resident Selection Process: Proposed Reforms and Lessons From Other Specialties.

INTRODUCTION: Proposals for substantive reforms to the orthopaedic resident selection process are growing, given increasing applicant competitiveness, burgeoning inefficiencies and inequities of the current system, and impending transition of Step 1 to pass/fail. The COVID-19 pandemic has further catalyzed the need for reforms, offering unprecedented opportunities to pilot novel changes. However, a comprehensive collation of all proposed and implemented orthopaedic reforms is currently lacking. Thus, we aimed to characterize proposed orthopaedic-specific resident selection reforms in the context of reforms implemented by other specialties. METHODS: EMBASE, MEDLINE, Scopus, and Web of Science databases were searched for references proposing reforms to the orthopaedic resident selection process published from 2005 to 2020. An inductive approach to qualitative content analysis was used to categorize reforms. RESULTS: Twenty-six articles proposing 13 unique reforms to the orthopaedic resident selection process were identified. The most commonly proposed reforms included noncognitive assessments (n = 8), application caps (n = 7), standardized letters of recommendation (n = 5), program-specific supplemental applications (n = 5), creation of a centralized database of standardized program information (n = 4), use of a standardized applicant composite score (n = 4), and a moratorium on postinterview communication (n = 4). Importantly, nearly all of these reforms have also been proposed or implemented by other specialties. DISCUSSION: Numerous reforms to the orthopaedic resident selection process have been suggested over the past 15 years, several of which have been implemented on a program-specific basis, including noncognitive assessments, supplemental applications, and standardized letters of recommendation. Careful examination of applicant and program experiences and Match outcomes after these reforms is imperative to inform future directions.

Statistical Assumptions in Orthopaedic Literature: Are Study Findings at Risk?

Background As orthopaedic surgery becomes more evidence-based, the need for rigorous research has increased. This results in more complex studies that employ more sophisticated statistical analysis, often some form of regression. These statistical techniques require the data to meet certain assumptions for the findings to be considered valid. The purpose of this study is to determine the common regression techniques employed in the orthopaedic surgery literature, and demonstrate how often the assumptions of regression analyses are met and reported. Methods Studies published in the Journal of Bone & Joint Surgery (JBJS) in 2017 and 2018 were reviewed. Commentaries, editorials, and systematic reviews were excluded. The statistical analyses performed in each study were documented. When regression analyses were utilized, the article was reviewed for evidence that the necessary assumptions underlying the statistical methodology were assessed and met. Results From the 470 studies that were reviewed, the most common statistical test reported was the independent-samples t-test (n=215, 45.7%). Also, 201 studies (42.8%) implemented some form of regression analysis. The most common regression was a logistic regression (n= 106). None of the 201 studies using regression analysis reported meeting all of the necessary assumptions to appropriately use a regression test. Conclusion Many recent studies published in JBJS depended on regression analyses to reach their conclusions, but none fully reported the necessary assumptions of these tests. Orthopaedic surgery journals should be more transparent in reporting the methodology of statistical tests, and readers must beware of possible gaps in statistical methodology and critically evaluate the studies' findings.

Systems-Level Reforms to the US Resident Selection Process: A Scoping Review.

BACKGROUND: Calls to reform the US resident selection process are growing, given increasing competition and inefficiencies of the current system. Though numerous reforms have been proposed, they have not been comprehensively cataloged. OBJECTIVE: This scoping review was conducted to characterize and categorize literature proposing systems-level reforms to the resident selection process. METHODS: Following Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines, searches of Embase, MEDLINE, Scopus, and Web of Science databases were performed for references published from January 2005 to February 2020. Articles were included if they proposed reforms that were applicable or generalizable to all applicants, medical schools, or residency programs. An inductive approach to qualitative content analysis was used to generate codes and higher-order categories. RESULTS: Of 10 407 unique references screened, 116 met our inclusion criteria. Qualitative analysis generated 34 codes that were grouped into 14 categories according to the broad stages of resident selection: application submission, application review, interviews, and the Match. The most commonly proposed reforms were implementation of an application cap (n = 28), creation of a standardized program database (n = 21), utilization of standardized letters of evaluation (n = 20), and pre-interview screening (n = 13). CONCLUSIONS: This scoping review collated and categorized proposed reforms to the resident selection process, developing a common language and framework to facilitate national conversations and change.

Experience Level Influences Users' Interactions With and Expectations For Online Surgical Videos: A Mixed-Methods Study.

PURPOSE: Upper-extremity surgeons and trainees widely use online surgical videos, and the use of these videos can assist with procedural learning. The purpose of this study was to characterize online video use and understand the role videos play in the learning process of orthopedic residents and practicing surgeons. We hypothesized that the use of surgical videos and video content desired among orthopedic learners differs based on their experience level. METHODS: Four focus groups were conducted to discuss online surgical videos and their role in the learning process of orthopedic learners. Participants were separated based on their experience level. Three reviewers qualitatively analyzed the transcripts of the focus groups using constant comparative methods to identify overarching themes and categories. Findings regarding the participants' desires for video content and production quality were translated into a survey. The survey results were analyzed to assess their associations with experience level. RESULTS: The focus group analysis helped identify 4 overarching themes that reflected users' interactions with videos: prewatching experience, choosing a video, video use, and video design, with the users' comments differing based on their experience level. The survey results showed that the median ideal length for a video was 10 minutes and that all users, regardless of their experience level, ranked showing the surgical procedure as the most important part of a video. Junior residents more frequently desired background information and a written outline of surgical steps, whereas more senior learners placed greater emphasis on advanced surgical decision-making and the use of particular implants/devices. CONCLUSIONS: Experience level influences users' interactions with videos, including how they are chosen and used, and their expectations in terms of content and production. CLINICAL RELEVANCE: Video creators should specify their targeted audience's experience level and adjust content to meet users' needs. Our results can provide video creators and hosts a checklist for appropriate content and production standards.

Comparison of machine learning techniques to predict unplanned readmission following total shoulder arthroplasty.

BACKGROUND: Machine learning (ML) techniques have been shown to successfully predict postoperative complications for high-volume orthopedic procedures such as hip and knee arthroplasty and to stratify patients for risk-adjusted bundled payments. The latter has not been done for more heterogeneous, lower-volume procedures such as total shoulder arthroplasty (TSA) with equally limited discussion around strategies to optimize the predictive ability of ML algorithms. The purpose of this study was to (1) assess which of 5 ML algorithms best predicts 30-day readmission, (2) test select ML strategies to optimize the algorithms, and (3) report on which patient variables contribute most to risk prediction in TSA across algorithms. METHODS: We identified 9043 patients in the American College of Surgeons National Surgical Quality Improvement Database who underwent primary TSA between 2011 and 2015. Predictors included demographics, comorbidities, laboratory data, and intraoperative variables. The outcome of interest was 30-day unplanned readmission. Five ML algorithms-support-vector machine (SVM), logistic regression, random forest (RF), an adaptive boosting algorithm, and neural network-were trained on the derivation cohort (2011-2014 TSA patients) to predict 30-day unplanned readmission rates. After training, weights for each respective model were fixed and the classifiers were evaluated on the 2015 TSA cohort to simulate a prospective evaluation. C-statistic and f1 scores were used to assess the performance of each classifier. After evaluation, features were removed independently to assess which features most affected classifier performance. RESULTS: The derivation and validation cohorts comprised 5857 and 3186 primary TSA patients, respectively, with similar demographics, comorbidities, and 30-day unplanned readmission rates (2.9% vs. 2.7%). Of the ML algorithms, SVM performed the worst with a c-statistic of 0.54 and an f1-score of 0.07, whereas the random-forest classifier performed the best with the highest c-statistic of 0.74 and an f1-score of 0.18. In addition, SVM was most sensitive to loss of single features, whereas the performance of RF did not dramatically decrease after loss of single features. Within the trained RF classifier, 5 variables achieved weights >0.5 in descending order: high bilirubin (>1.9 mg/dL), age >65, race, chronic obstructive pulmonary disease, and American Society of Anesthesiologists' scores ≥3. In our validation cohort, we observed a 2.7% readmission rate. From this cohort, using the RF classifier we were then able to identify 436 high-risk patients with a predicted risk score >0.6, of whom 36 were readmitted (readmission rate of 8.2%). CONCLUSION: Predictive analytics algorithms can achieve acceptable prediction of unplanned readmission for TSA with the RF classifier outperforming other common algorithms.

A Failed 4-Corner Arthrodesis Using a Polyether-Ether-Ketone Implant: A Case Report.

CASE: A 59-year-old man underwent scaphoidectomy and 4-corner arthrodesis with a polyether-ether-ketone (PEEK) circular plate for scapholunate advanced collapse of the wrist. Five years later, he presented with a symptomatic nonunion and radiocarpal arthritis. Total wrist arthrodesis with a dorsal plate was performed. During revision surgery, considerable synovitis was encountered. Histological evaluation revealed a foreign body response likely secondary to PEEK particles. CONCLUSION: Use of PEEK implants can result in an adverse local tissue reaction if particles are generated. This is a rare biomaterial-related complication, and surgeons should be aware of this adverse tissue response when using this or other PEEK implants.

The ulnohumeral arthroplasty: technical tips for safely managing the brachial artery.

One surgical option to manage idiopathic osteoarthritis of the elbow is an ulnohumeral arthroplasty. A potential complication to avoid during this procedure is inadvertent over penetration of the anterior cortex of the humerus. If this occurs, injury to the median nerve and brachial artery is possible as these structures may lie within 7 mm of the anterior humerus. This surgical technique describes technical tips in regards to patient positioning and specific instrument usage that serve to diminish the risk of this catastrophic complication occurring by allowing these critical neurovascular structures to fall away from the anterior humerus.
