How Does ChatGPT Use Source Information Compared With Google? A Text Network Analysis of Online Health Information.

BACKGROUND: The lay public is increasingly using ChatGPT (a large language model) as a source of medical information. Traditional search engines such as Google provide several distinct responses to each search query and indicate the source for each response, but ChatGPT provides responses in paragraph form in prose without providing the sources used, which makes it difficult or impossible to ascertain whether those sources are reliable. One practical method to infer the sources used by ChatGPT is text network analysis. By understanding how ChatGPT uses source information in relation to traditional search engines, physicians and physician organizations can better counsel patients on the use of this new tool. QUESTIONS/PURPOSES: (1) In terms of key content words, how similar are ChatGPT and Google Search responses for queries related to topics in orthopaedic surgery? (2) Does the source distribution (academic, governmental, commercial, or form of a scientific manuscript) differ for Google Search responses based on the topic's level of medical consensus, and how is this reflected in the text similarity between ChatGPT and Google Search responses? (3) Do these results vary between different versions of ChatGPT? METHODS: We evaluated three search queries relating to orthopaedic conditions: "What is the cause of carpal tunnel syndrome?," "What is the cause of tennis elbow?," and "Platelet-rich plasma for thumb arthritis?" These were selected because of their relatively high, medium, and low consensus in the medical evidence, respectively. Each question was posed to ChatGPT version 3.5 and version 4.0 20 times for a total of 120 responses. Text network analysis using term frequency-inverse document frequency (TF-IDF) was used to compare text similarity between responses from ChatGPT and Google Search. In the field of information retrieval, TF-IDF is a weighted statistical measure of the importance of a key word to a document in a collection of documents. Higher TF-IDF scores indicate greater similarity between two sources. TF-IDF scores are most often used to compare and rank the text similarity of documents. Using this type of text network analysis, text similarity between ChatGPT and Google Search can be determined by calculating and summing the TF-IDF for all keywords in a ChatGPT response and comparing it with each Google search result to assess their text similarity to each other. In this way, text similarity can be used to infer relative content similarity. To answer our first question, we characterized the text similarity between ChatGPT and Google Search responses by finding the TF-IDF scores of the ChatGPT response and each of the 20 Google Search results for each question. Using these scores, we could compare the similarity of each ChatGPT response to the Google Search results. To provide a reference point for interpreting TF-IDF values, we generated randomized text samples with the same term distribution as the Google Search results. By comparing ChatGPT TF-IDF to the random text sample, we could assess whether TF-IDF values were statistically significant from TF-IDF values obtained by random chance, and it allowed us to test whether text similarity was an appropriate quantitative statistical measure of relative content similarity. To answer our second question, we classified the Google Search results to better understand sourcing. Google Search provides 20 or more distinct sources of information, but ChatGPT gives only a single prose paragraph in response to each query. So, to answer this question, we used TF-IDF to ascertain whether the ChatGPT response was principally driven by one of four source categories: academic, government, commercial, or material that took the form of a scientific manuscript but was not peer-reviewed or indexed on a government site (such as PubMed). We then compared the TF-IDF similarity between ChatGPT responses and the source category. To answer our third research question, we repeated both analyses and compared the results when using ChatGPT 3.5 versus ChatGPT 4.0. RESULTS: The ChatGPT response was dominated by the top Google Search result. For example, for carpal tunnel syndrome, the top result was an academic website with a mean TF-IDF of 7.2. A similar result was observed for the other search topics. To provide a reference point for interpreting TF-IDF values, a randomly generated sample of text compared with Google Search would have a mean TF-IDF of 2.7 ± 1.9, controlling for text length and keyword distribution. The observed TF-IDF distribution was higher for ChatGPT responses than for random text samples, supporting the claim that keyword text similarity is a measure of relative content similarity. When comparing source distribution, the ChatGPT response was most similar to the most common source category from Google Search. For the subject where there was strong consensus (carpal tunnel syndrome), the ChatGPT response was most similar to high-quality academic sources rather than lower-quality commercial sources (TF-IDF 8.6 versus 2.2). For topics with low consensus, the ChatGPT response paralleled lower-quality commercial websites compared with higher-quality academic websites (TF-IDF 14.6 versus 0.2). ChatGPT 4.0 had higher text similarity to Google Search results than ChatGPT 3.5 (mean increase in TF-IDF similarity of 0.80 to 0.91; p < 0.001). The ChatGPT 4.0 response was still dominated by the top Google Search result and reflected the most common search category for all search topics. CONCLUSION: ChatGPT responses are similar to individual Google Search results for queries related to orthopaedic surgery, but the distribution of source information can vary substantially based on the relative level of consensus on a topic. For example, for carpal tunnel syndrome, where there is widely accepted medical consensus, ChatGPT responses had higher similarity to academic sources and therefore used those sources more. When fewer academic or government sources are available, especially in our search related to platelet-rich plasma, ChatGPT appears to have relied more heavily on a small number of nonacademic sources. These findings persisted even as ChatGPT was updated from version 3.5 to version 4.0. CLINICAL RELEVANCE: Physicians should be aware that ChatGPT and Google likely use the same sources for a specific question. The main difference is that ChatGPT can draw upon multiple sources to create one aggregate response, while Google maintains its distinctness by providing multiple results. For topics with a low consensus and therefore a low number of quality sources, there is a much higher chance that ChatGPT will use less-reliable sources, in which case physicians should take the time to educate patients on the topic or provide resources that give more reliable information. Physician organizations should make it clear when the evidence is limited so that ChatGPT can reflect the lack of quality information or evidence.

Complications and Unplanned Reoperation After Thumb Metacarpophalangeal Arthrodesis.

PURPOSE: Arthrodesis of the metacarpophalangeal (MCP) joint of the thumb is a common procedure to treat arthritis or instability. Studies reporting hardware complications and nonunion rates after thumb MCP joint arthrodesis report on small sample sizes. We aimed to describe the hardware complication rate, the nonunion rate, and the number of thumbs that achieve union among patients undergoing thumb MCP joint arthrodesis. METHODS: A database spanning 5 urban hospitals in a single metropolitan region in the United States was searched for patients who underwent thumb MCP joint arthrodesis between January 1, 2004 and January 1, 2020. After reviewing patient records, we identified 122 thumbs that underwent MCP joint arthrodesis and had a minimum follow-up of 90 days. The primary outcome was unplanned reoperation after hardware complications and nonunion. Second, the number of thumbs that achieved radiographic union was reported for the tension band and screw fixation arthrodesis group. RESULTS: Twenty-two (18%) out of 122 thumbs had hardware complications after thumb MCP joint arthrodesis, and 11 (9%) out of 122 thumbs developed a nonunion. Patients who underwent screw fixation arthrodesis had no events of hardware complications and subsequent hardware removal. The nonunion rate was 9/65 (14%) in the tension band arthrodesis group and 2 (4%) of 45 in the screw fixation arthrodesis group. Of the thumbs that had available radiographs to assess the healing of the arthrodesis, 34 (81%) of 42 were radiographically united in the tension band arthrodesis group and 29 (91%) of 32 in the screw fixation group. CONCLUSIONS: Our data suggest that screw fixation has fewer hardware complications and a lower reoperation rate than tension band arthrodesis. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

Does Revision Carpal Tunnel Release Result in Long-Term Outcomes Equivalent to Single Carpal Tunnel Release? A Matched Case-Control Analysis.

BACKGROUND: The aims of this study were to evaluate long-term patient-reported outcomes after revision carpal tunnel release (CTR); compare these outcomes with those of patients who had a single CTR and a comparable age, sex, race, type of initial surgery, and follow-up time; and assess which factors are associated with worse patient-reported outcomes after revision CTR. METHODS: The authors retrospectively identified 7351 patients who had a single CTR and 113 patients who had a revision CTR for carpal tunnel syndrome between January of 2002 and December of 2015 at five academic urban hospitals. Of these 113 revision CTR cases, 37 patients completed a follow-up questionnaire including the Boston Carpal Tunnel Questionnaire (BCTQ), the Numerical Rating Scale for Pain Intensity, and satisfaction score. Those who completed the follow-up questionnaire were randomly matched to five controls (patients who had a single CTR) based on age, sex, race, type of initial surgery, and follow-up time. Of these 185 matched controls, 65 completed the follow-up questionnaire. RESULTS: A linear mixed effects model using matched sets as a random effect showed that patients who had a revision CTR had a higher total BCTQ score, Numerical Rating Scale for Pain Intensity score, and a lower satisfaction score at time of follow-up than patients who had a single CTR. Multivariable linear regression showed that thenar muscle atrophy before the revision surgery was independently associated with more pain after revision surgery. CONCLUSION: Patients improve after revision CTR, but generally have more pain, have a higher BCTQ score, and are less satisfied at long-term follow-up compared with patients who had a single CTR.

DRUJ Capsular Release for Forearm Rotational Limitation: Surgical Technique and Case Series.

BACKGROUND: Forearm stiffness can be caused by distal radioulnar joint (DRUJ) capsular contractures, which can occur after trauma such as a distal radius fracture. In this setting, a DRUJ capsular release may help improve forearm rotation, but the long-term functional outcomes remain unknown. The purpose of this case series is to investigate the short-term improvement in total pronosupination arc range of motion and long-term patient-reported outcomes (PROs) after DRUJ capsular release. METHODS: We performed a retrospective review of consecutive patients who underwent DRUJ capsular release. Range of motion prior to surgery and at final short-term follow-up was collected and analyzed with a Wilcoxon signed-rank test. Patient-reported outcomes including QuickDASH and Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) scores were obtained as medians with interquartile range (IQR), while patient satisfaction was measured on a 4-point Likert scale. RESULTS: Five patients met the inclusion criteria with a median short-term follow-up of 5.5 (IQR: 4.3-10.3) months. The median preoperative supination was 25° (IQR: 0°-35°), and the median postoperative supination was 50° (IQR: 40°-60°; P = .03). The median preoperative pronation was 45° (IQR: 10°-60°), and the median postoperative pronation was 70° (IQR: 60°-80°; P = .04). After the long-term median follow-up of 10.9 (IQR 9.7-11.2) years, all the patients were satisfied or very satisfied with the results of the surgery. The median QuickDASH score was 13.6 (IQR: 9.1-20.5), and the median PROMIS UE score was 46.5 (IQR: 43.8-47.7). CONCLUSIONS: Distal radioulnar joint capsular release can improve pronation and supination in patients with posttraumatic forearm stiffness and is associated with high long-term patient satisfaction.

Trends in Distal Radius Fixation Reimbursement, Charge, and Utilization in the Medicare Population.

Background Distal radius fractures (DRF) are the second most common fragility fracture experienced by the elderly, and surgical management constitutes an appreciable sum of Medicare expenditure for upper extremity surgery. Using Medicare data from 2012 to 2017, our primary aim was to describe temporal changes in surgical treatment, physician payment, and patient charges for DRF fixation. Methods We examined surgical volumes and retrospective patient charge (services billed by surgeon) and surgeon payment (professional fee) data from 2012 to 2017 for four DRF surgeries: closed reduction percutaneous pinning (CRPP), open reduction internal fixation (ORIF) of extra-articular fractures, ORIF of intra-articular (IA) (2-fragment) fractures, and ORIF of IA (> 3 fragments) fractures. The reimbursement ratio was defined and calculated as the ratio of charges to payment. Rates were adjusted for inflation using the annual consumer-price index. Results For these four surgeries from 2012 to 2017, total patient charges grew by 64% from $117 to 193 million, while surgeon payment grew by 42% from $30 to 42 million. CRPP cases fell by 47%, while ORIF increased by 17, 14, and 45% for extra-articular, IA (2-fragment), and IA (> 3 fragments) surgeries, respectively. After adjusting for inflation, payment to physicians increased by more than or equal to 16% for all procedures except for CRPP, which fell by 2%. Charges during this same period increased from 13 to 38%. Reimbursement ratios declined from -9.2% to -13% for each procedure. Conclusion From 2012 to 2017, while charges have outpaced surgeon payment, payment has outpaced inflation for all forms of distal radius ORIF, aside from CRPP. There has been a continued sharp decline of CRPP. Level of Evidence is III, economic.

Operative Trends in Orthopaedic Hand Surgery Fellowships.

Objective Since 1958, more than 50 postresidency fellowship programs in hand surgery have been introduced within the United States. Ongoing changes in health care and medical education necessitate the evaluation of these fellowships. The purpose of this study is to identify trends in operative experience over time regarding procedure volume, surgery type, and anatomic region. Materials and Methods National Accreditation Council for Graduate Medical Education (ACGME) case logs of graduating orthopaedic hand surgery fellows were evaluated for years 2011 to 2019. Procedures were grouped according to ACGME-defined categories for hand surgery. The mean number of procedures per fellow in each category was trended over time using a Mann-Kendall test. Results All 1,257 fellows were included. The mean number of procedures completed annually by each fellow increased from 797.6 in 2011 to 945.6 in 2019 ( p < 0.01). Over the course of the study period, there were increases in the number of "soft tissue," "fracture," and "nerve" procedures ( p < 0.001), while the number of "congenital" procedures decreased ( p < 0.05). Additionally, small but statistically significant increases were found in "amputation," "Dupuytren's," and "decompression of tendon sheath/synovectomy/ganglions" procedures ( p < 0.01). Conclusion There has been an increase in the number of procedures performed by orthopaedic hand surgery fellows over the past decade. This appears to be due to the increase in nerve, fracture, and soft tissue categories, and there has been a decrease in the number of congenital cases completed. These data confirm that the operative experiences for most hand surgery fellows are robust and growing over time.

Quantitative 3-D CT Demonstrates Distal Row Pronation and Translation and Radiolunate Arthritis in the SNAC Wrist.

BACKGROUND: In scaphoid nonunion advanced collapse (SNAC) wrist arthritis, we analyzed the 3-dimensional (3-D) deformity patterns of carpal alignment secondary to scaphoid nonunion and quantified subchondral arthritis by investigating alterations in bone density. METHODS: We constructed 3-D models of the carpal bones and radius from 51 patients with scaphoid nonunion (nonunion group) and 50 healthy controls (control group). We quantified the differences in 3-D geometric position of the distal carpal row relative to the distal radius in SNAC wrists versus controls. In addition, we assessed the bone density of anatomic regions of interest in the radiocarpal and capitolunate joints relative to the pisiform bone density to characterize degenerative changes in SNAC wrists. RESULTS: The distal carpal row pronated by a difference of 14° (7.2° versus -6.7°; p < 0.001), deviated ulnarly by a difference of 19° (7.7° versus -11.2°; p < 0.001), shifted dorsally by a difference of 17% of the dorsovolar width of the distal radius (21.0% versus 4.4%; p < 0.001), shifted radially by a difference of 8% of the radioulnar width of the distal radius (13.2% versus 5.3%; p < 0.001), and migrated proximally by a difference of 12% of the lunate height (96.3% versus 108.8%; p < 0.001) in the nonunion group compared with the control group. Additionally, it was found that bone density was greater at the capitolunate joint (capitate head: 140.4% versus 123.7%; p < 0.001; distal lunate: 159.9% versus 146.3%; p < 0.001), the radial styloid (157.0% versus 136.3%; p < 0.001), and the radiolunate joint (proximal lunate: 134.8% versus 122.7%; p < 0.001; lunate fossa: 158.6% versus 148.1%; p = 0.005) in the nonunion group compared with the control group. CONCLUSIONS: Scaphoid nonunion exhibited a unique deformity pattern and alteration in bone-density distributions. The distal carpal row not only shifted dorsally and migrated proximally but also pronated, deviated ulnarly, and shifted radially. Bone density was greater at the capitolunate joint, the radial styloid, and surprisingly, the radiolunate joint. Our findings give insight into the natural history and progression of arthritis of the SNAC wrist. Additionally, future studies may give insight into whether successful treatment of scaphoid nonunion arrests the progression of arthritis. LEVEL OF EVIDENCE: Prognostic Level III .

Revision Arthroplasty in the Challenging Elbow.

Compared with hip and knee arthroplasty, total elbow arthroplasty (TEA) has a higher complication rate and lower survivorship. Modern TEA implants most commonly require revision due to implant loosening, infection, and periprosthetic fracture. Concerns with revision TEA include handling of the soft tissues and possible necessity of flap coverage, triceps management, preservation of bone stock, and management of concurrent infection or fracture. In this review, we will discuss preoperative evaluation of the failed elbow arthroplasty, surgical approaches, techniques for revision, outcomes, and complications following revision total elbow arthroplasty.

Factors Associated with Prolonged Opioid Use after CMC Arthroplasty.

Background Higher rates of prolonged opioid use have been reported in patients who undergo thumb carpometacarpal (CMC) arthroplasty compared with other hand procedures. Therefore, the aim of this study is to identify the risk factors associated with prolonged postoperative opioid use after CMC arthroplasty, along with reporting the number of patients who filled an opioid prescription more than 30 days postoperatively. Materials and Methods Retrospectively, 563 opioid-naïve patients who underwent CMC arthroplasty were included. A manual chart review was performed to collect patient characteristics, and opioid use was determined based on opioid prescription by a physician. Prolonged opioid use was defined as an opioid prescription at 90 to 180 days postoperatively. A multivariable analysis was performed to identify independent factors associated with an opioid prescription at 90 to 180 days postoperatively. Patients had a median age of 60.4 years (interquartile range [IQR]: 55.5-66.9) and had a median follow-up of 7.6 years (IQR: 4.3-12.0). Results The rates of postoperative opioid use ranged from 6.2% (53 out of 563 patients) at 30 to 59 days postoperatively to 3.9% (22 out of 563 patients) at 150 to 180 days postoperatively. In total, 17.1% (96 out of 563 patients) received a second opioid prescription more than 30 days following surgery, of which 10.8% (61 out of 563 patients) were between 90 and 180 days postoperatively. Older age, defined as a median of 63 years (IQR: 57.10-69.88) ( p = 0.027, odds ratio [OR] = 1.04) and a history of psychiatric disease ( p = 0.049, OR = 1.86) were independently associated with prolonged opioid use. Conclusion A prolonged opioid use rate of roughly 11% was found in opioid-naïve patients who underwent CMC arthroplasty. In patients at risk (older patients or psychiatric history) of prolonged opioid use, careful postoperative pain management is recommended.

Reintervention, PROMs, and Factors Influencing PROMs Following Surgery for de Quervain's Tenosynovitis.

Objective The aims of this study are to describe and identify the factors that influence patient reported outcomes following surgery of de Quervain's tenosynovitis. The secondary objective is to report the rate of reintervention following surgery of de Quervain's tenosynovitis. Patients and Methods Outcomes using the numerical rating scale (NRS) for pain, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), Patient-Rated Wrist Evaluation (PRWE), the Patients Reported Outcome Measurement Information System Pain Interference (PROMIS PI), and a custom de Quervain's questionnaire were obtained. A multivariable linear regression analysis was performed to identify independent factors associated with patient-reported outcomes. Results Seventy-six patients who underwent de Quervain's release participated. The average age was 52.8 years (95% confidence interval: 49.6-56.1) and median follow-up age was 7.0 years (interquartile range [IQR]: 4.3-12.0). Outcomes were: NRS of pain was 0 (IQR: 0.0-3.0), the median QuickDASH was 6.82 (IQR: 0.00-28.41), the median PRWE score was 4.0 (IQR: 0.00-18.50), and the median PROMIS PI score was 43.90 (IQR: 38.70-53.90). Eighteen (23.7%) of the patients reported pain with thumb activities, four of whom had a reintervention. Additionally, 21 (26.9%) patients reported decreased strength in the thumb compared to the contralateral side, of which two underwent a reintervention. In total, eight patients underwent reintervention of which seven had a second surgery and one had a cortisone injection. Conclusion Roughly 1 in 20 patients following de Quervain's release undergoes reintervention. Patients with high PROMIS PI scores report poor surgical outcomes more frequently. Patients with high PROMIS PI scores report higher NRS pain scores ( p < 0.05), higher QuickDASH scores ( p < 0.05), and higher PRWE scores ( p < 0.05). In practice, careful consideration of PROMIS PI scores and psychosocial factors are recommended before considering reintervention.

Functional outcomes and complications after treatment of distal radius fracture in patients sixty years and over: A systematic review and network meta-analysis.

AIM: This network meta-analysis aims to compare functional outcomes and complications between conservative treatment and surgery for distal radius fractures in patients aged 60 years and over. METHODS: We searched the PubMed, EMBASE, and Web of Science databases for randomized controlled trials (RCTs) assessing the effect of conservative treatment and surgery for distal radius fractures in patients aged 60 years and over. Primary outcomes included grip strength and overall complications. Secondary outcomes included Disabilities of the Arm, Shoulder, and Hand (DASH) scores, Patient-Rated Wrist Evaluation (PRWE) scores, wrist range of motion and forearm rotation, and radiographic assessment. All continuous outcomes were assessed using standardized mean differences (SMDs) with 95% confidence intervals (CIs), and binary outcomes were assessed using odds ratio (OR) with 95% CIs. The surface under the cumulative ranking curve (SUCRA) was used to determine a hierarchy of treatments. Cluster analysis was performed for grouping treatments based on the SUCRA values of primary outcomes. RESULTS: Fourteen RCTs were included to compare conservative treatment, volar lockedplate (VLP), K-wires fixation, and external-fixation. VLP outperformed conservative treatment for 1-year and minimum 2-year grip strength (SMD; 0.28 [0.07 to 0.48] and 0.27 [0.02 to 0.53], respectively). VLP yielded the optimal grip strength at 1-year and minimum 2-year follow-up (SUCRA; 89.8% and 86.7%, respectively). In a subgroup analysis of patients aged 60 to 80 years old, VLP outperformed conservative treatment in DASH and PRWE scores (SMD, 0.33 [0.10, 0.56] and 0.23 [0.01, 0.45], respectively). In addition, VLP had the fewest complications (SUCRA = 84.3%). Cluster analysis suggested that VLP and K-wire fixation were more effective treatment groups. CONCLUSION: Evidence to date demonstrates that VLP provides measurable benefits in grip strength and fewer complications to those 60 years of age and over, and that benefit is not reflected in current practice guidelines. There is a subgroup of patients where K-wire fixation outcomes are similar to those of VLP; defining this subgroup may yield substantial societal benefits.

Reoperation Following Zone II Flexor Tendon Repair.

BACKGROUND: The goal of zone II flexor tendon surgery is to perform a repair with sufficient strength to withstand the forces encountered during rehabilitation. Postoperative rerupture and adhesion formation may lead to reoperation. This study aimed to determine the factors associated with reoperation after primary zone II flexor tendon repair. METHODS: In this retrospective case series, a total of 252 fingers in 201 patients underwent zone II flexor tendon repair. A medical record review was performed to collect data regarding patient demographics, injury and treatment characteristics and postoperative complications including reoperation. Reoperation was defined as any unplanned surgical procedure performed after initial flexor tendon repair. RESULTS: There were 49 fingers (19%) in 42 patients that underwent reoperation at a median of 5.5 (interquartile range: 2.8-7.9) months. Older age, workers' compensation, and a Kessler-type repair of the flexor digitorum profundus were independently associated with reoperation. CONCLUSIONS: In vitro studies suggest that Kessler-type repairs are inferior compared with other suture configurations. Our study demonstrates a clinical correlation to these biomechanical studies. Our results suggest that Kessler-type repairs are inferior compared with non-Kessler-type repairs, due to postoperative complications requiring secondary surgeries.

Impact of COVID-19 on the Work, Health, and Quality of Life of Brazilian Hand Surgeons.

BACKGROUND: To evaluate the impact of coronavirus disease 2019 (COVID-19) on the clinical practice, health, and quality of life of Brazilian hand surgeons when only essential services and emergency procedures were being provided. METHOD: A questionnaire of 50 questions was sent to members of the Brazilian Society of Hand Surgery addressing work and life routines before the pandemic and during the initial quarantine period from April to August 2020. RESULTS: Two hundred ten hand surgeons answered the questionnaire; 55.2% lived in the southeast region and worked in the capital and metropolitan regions, in both the private and public systems. Thirty-eight percent of the sample had other sources of income besides medicine, and due to a drop of 50% or more in the volume of consultations and surgeries, one-third had to apply for financial loans or access personal savings, and 69% made financial cuts in their domestic and life routines. More than 40% gained weight and stopped doing physical activities, while 20% lost weight and started physical activities. Approximately 30% were diagnosed with COVID-19, 92% of whom had mild symptoms and quarantined at home, and 89% had psychological symptoms such as anxiety, fear, insecurity, and insomnia. CONCLUSIONS: Coronavirus disease 2019 had a significant impact on the lives of Brazilian hand surgeons by drastically reducing the number of consultations and surgical procedures, generating not only financial difficulties but also changes in the exercise routine, changes in body weight, associated psychological symptoms, and changes in the family/life routine.

Reoperation After Operative Treatment of Open Finger Fractures.

BACKGROUND: Our primary aim was to develop a prediction model for return to the operating room (OR) after open finger fractures by studying the reoperation rate of open finger fractures based on patient demographics, injury mechanism, injury severity, and type of initial surgical fixation. The secondary aim was to study the predictors for secondary surgery due to nonunion, postoperative infection, and secondary amputation. METHODS: In the retrospective chart review, 1321 open finger fractures of 907 patients were included. Demographic-, injury-, and treatment-related factors were gathered from medical records. RESULTS: We found that open fractures involving the thumb had lower odds of undergoing secondary surgery. Crush injury, proximal phalangeal fracture, arterial injury, other injured fingers, and other injuries to the ipsilateral hand were associated with higher odds of undergoing secondary surgery. However, the associated factors we identified were not powerful enough to create a predictive model. Other injury to the ipsilateral hand, vein repair, and external fixator as initial treatment were associated with postoperative nonunion. Crush injury and proximal phalangeal fracture were associated with postoperative infection. No factors were associated with secondary amputation. CONCLUSIONS: A quarter of open finger fractures will likely need more than one surgical procedure, especially in more severely injured fingers, due to crush or with vascular impairment. Furthermore, fractures involving the thumb have less reoperation, while fractures involving the proximal phalanx have poorest outcomes.

Patient-Reported Outcomes After Surgical Treatment of Early Osteoarthritis of the First Carpometacarpal Joint.

BACKGROUND: The goals of this study are to describe the reoperation rates in patients who underwent Wilson osteotomy compared with patients who underwent carpometacarpal (CMC) arthroplasty for early-stage arthritis and to evaluate the factors influencing the patient-reported outcomes. METHODS: Retrospectively, 52 patients who underwent surgery for stage I/II osteoarthritis of the thumb carpometacarpal were identified, consisting of 17 (33%) patients who underwent Wilson osteotomy and 35 (67%) who underwent carpometacarpal arthroplasty. A total of 28 (55%) patients completed the outcome questionnaires, consisting of 11 (39%) patients who underwent Wilson osteotomy and 17 (61%) patients who underwent carpometacarpal arthroplasty. We performed a multivariable linear regression model to identify factors associated with the Numeric Rating Scale (NRS) pain intensity at final follow-up. RESULTS: Among the patients who underwent CMC arthroplasty, 2 had a reoperation. Among the patients who underwent Wilson osteotomy, 3 had a reoperation. Among the patients who completed the outcome questionnaires, the median quick Disabilities of the Arm, Shoulder and Hand score was 10 and the median NRS Pain Intensity score was 0. In multivariable analysis, the postoperative Patient-Reported Outcomes Measurement Information System Pain Interference (PROMIS PI) was independently associated with higher postoperative NRS pain scores. CONCLUSION: In younger patients with stage I/II CMC osteoarthritis, Wilson osteotomy may be a reasonable alternative to CMC arthroplasty. Outcomes were similar between both groups at mid-term follow-up, with only a slightly higher pain score in the osteotomy group. In patients with stage I/II carpometacarpal osteoarthritis, the PROMIS PI is the main factor indicating successful outcomes.

Quantitative Analysis of the Volar Ulnar Corner of the Distal Radius: A Reference for Intraoperative Distal Radius Fracture Reduction.

PURPOSE: The reduction of distal radius fractures using volar locking plate fixation can be performed by securing the plate to the distal fragments and then levering the plate to the radial shaft. Oblique placement of the plate on the radial shaft may lead to malreduction. The aim of this study was to evaluate parameters that can be used for the assessment of intraoperative distal radius fracture reduction using "distal-first" volar plate fixation, especially the geometry of the ulnar corner. The prevalence of Tolat distal radioulnar joint (DRUJ) types was determined, and the angles of the volar corner were quantitatively described. METHODS: Three hundred seventy-five adult patients with a conventional wrist radiograph in their medical chart were identified. From this cohort, 50 radiographs of each Tolat DRUJ type were quantitatively analyzed using 4 angles. The probability density of each angle was described using Kernel density estimation graphs. A multivariable analysis was used to study the association between the 4 angles and Tolat DRUJ types and other patient factors. RESULTS: One hundred fifty-one patients (40%) had a wrist with type 1 DRUJ, 147 (39%) had a wrist with type 2 DRUJ, and 77 (21%) had a wrist with type 3 DRUJ. The measurements of the distal ulnar corner, volar ulnar corner, and DRUJ angulation were significantly different among each Tolat DRUJ type. The median lunate facet inclination, relative to the axis of the radial shaft, measured 14° (interquartile range, 12°-16°) across all the Tolat DRUJ types. CONCLUSIONS: The prevalence of Tolat type 1, 2, and 3 DRUJ was 40%, 39%, and 21%, respectively. The angles of the volar ulnar corner varied with each DRUJ type. CLINICAL RELEVANCE: Because the lunate facet inclination was relatively consistent among all the Tolat DRUJ types, this angle may be useful as a reference for "distal-first" distal radius volar plating.

Epidemiology and Fracture Patterns of Traumatic Phalangeal Fractures.

Background: Despite the relatively high incidence of phalangeal fractures, there is an imperfect understanding of the epidemiology and anatomical distribution of these fractures. This study describes the patient characteristics, anatomic distribution, and detailed fracture patterns of phalangeal fractures among a large adult cohort in the United States. Methods: A retrospective study was performed among patients with phalangeal fractures in the United States between January 2010 and January 2015. Included patients were 18 years old or older and had a diagnosis of a phalangeal fracture. A total of 2140 phalangeal fractures in 1747 patients were included, and a manual chart review was performed to collect epidemiological and radiographic information. Fractures were classified based on location and fracture pattern. Results: The median age at the time of injury was 45 years (interquartile range, 30-57), and 65% of patients were men. The small finger had the highest incidence of fractures (26%) followed by the ring finger (24%). Distal and proximal phalanges demonstrated the highest incidence of fractures at 39% each. The dominant hand was affected in 44% of cases. Eighteen percent of fractures were due to a work-related trauma mechanism, and the most common mechanism of injury was blunt trauma (46%). Conclusion: This study provides a detailed overview of the anatomic distribution and fracture patterns of phalangeal fractures in an adult US population and, thus, may aid hand surgeons treating these injuries.

Forearm Plate Fixation: Should Plates Be Removed?

Background: Refracture after both bone forearm fracture fixation may vary with or without plate removal. We tested the null hypothesis that there is no difference in the rate of refracture in patients who have undergone open reduction and internal fixation of a diaphyseal forearm bone who have retained implants versus removed implants. We also studied factors associated with plate removal. Methods: We retrospectively identified 645 adult patients with a total of 925 primary fractures that underwent primary plate fixation of an ulnar or radial shaft fracture between 2002 and 2015 at a single institutional system. Patients with nonunion, pathological fracture or infection were excluded. Independent factors associated with refracture and plate removal were identified using multivariable analysis. Results: Refractures occurred in 6.3% of the fractures that had forearm implant removal, compared to 2.1% of the fractures with retained plates. Refractures were independently associated with plate removal (OR: 3.7, 95% CI: 1.2-11.7, P=0.023) and was more frequent in the radius (OR: 2.4, 95% CI: 1.0-5.8, P=0.06). A refracture after implant removal occurred within 3 months after removal. Ulnar plates were removed more often compared to radial plates (OR: 2.6, 95% CI: 1.4-4.7, P=0.002) as were plates used for type A fractures compared to type C fractures (OR: 3.2, 95% CI: 1.1-9.2, P=0.032). Conclusion: The rate of refracture is higher after plate removal compared to patients who did not have plates removed. Although uncommon, refractures of the radius tend to be more common than a refracture of the ulna. If the implant is symptomatic on the ulnar side, it may be preferable to remove the ulnar implant and retain the radius implant rather than remove both plates when possible. Furthermore, limiting strenuous activity for three months after implant removal is a consideration.

Prolonged Opioid Use following Hand Surgery: A Systematic Review and Proposed Criteria.

Prolonged opioid use after surgery has been a contributing factor to the ongoing opioid epidemic. The purpose of this systematic review is to analyze the definitions of prolonged opioid use in prior literature and propose appropriate criteria to define postoperative prolonged opioid use in hand surgery. Methods: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines 130 studies were included for review. The primary outcome was the timepoint used to define prolonged opioid use following surgery. The proportion of patients with prolonged use and risk factors for prolonged use were also collected for each study. Included studies were categorized based on their surgical specialty. Results: The most common timepoint used to define prolonged opioid use was 3 months (n = 86, 67.2% of eligible definitions), ranging from 1 to 24 months. Although 11 of 12 specialties had a mean timepoint between 2.5 and 4.17 months, Spine surgery was the only outlier with a mean of 6.90 months. No correlation was found between the definition's timepoint and the rates of prolonged opioid use. Conclusions: Although a vast majority of the literature reports similar timepoints to define prolonged postoperative opioid use, these studies often do not account for the type of procedures being performed. We propose that the definitions of postoperative prolonged opioid use should be tailored to the level and duration of pain for specific procedures. We present criteria to define prolonged opioid use in hand surgery.
