Pediatric Scaphoid Nonunions: Does Insurance Status Play a Role?

Objective: There are no studies that evaluate the effects that insurance or socioeconomic status may have on treatment and outcomes of scaphoid nonunions in children. We evaluated whether there is an association between insurance status and (1) time from injury to hand surgeon evaluation, (2) time from specialist evaluation to surgery, and (3) postoperative outcomes of scaphoid fracture nonunions in children. Methods: A chart review was performed for patients who underwent surgical treatment of scaphoid fracture nonunion from January 2015 and April 2021 at a large tertiary care pediatric hospital. Underinsured patients were defined as those with no medical insurance or Medicaid/state-funded insurance. Results: There were 21 privately insured patients and 17 patients who were underinsured. There was no difference in age, race, or fracture characteristics between the two groups. The mean time between injury and hand surgeon evaluation was 192 SD 195 days for the privately insured group compared with 155 SD 205 days for the underinsured group (P = 0.57). The mean time between specialist evaluation and surgical treatment was 35 SD 54 days for the privately insured group and 31 SD 31 days for the underinsured group (P = 0.82). Union was achieved in 80% of patients with private insurance compared with 88% of underinsured patients after primary surgery (P = 0.67). There was no difference detected in the proportion of patients who had residual pain (15% vs 19%), range of motion deficits (38% vs 40%), strength deficit (6% vs 7%), and return to activity (94% vs 93%) between privately insured and underinsured patients, respectively (P = 1.00). Conclusions: There was no difference in time from injury to specialist evaluation, time from evaluation to surgery, or postoperative outcomes based on insurance status for pediatric patients with scaphoid fracture nonunions. Although insurance status was not associated with access to care for pediatric scaphoid fracture nonunions at our institution, this information may not be generalizable to other populations, including patients who sustain primary scaphoid fractures and who have not yet developed nonunions.

Emergency hand surgery in the course of time : Clinical and economic aspects of inpatient and outpatient cases at auniversity hospital in the last decade

Hand surgery departments nowadays face the challenge of operating profitably, training new specialists, managing increasing case numbers and implementing the required shift towards outpatient care in clinical practice. The aim of this study was to describe the demographic and economic indicators of auniversity hospital and to examine the development of inpatient and outpatient case numbers over the past decade. Aretrospective data analysis was carried out for patients treated for hand injuries in the period from 2013 to 2023. The main diagnoses of cases were identified and descriptively analyzed using the International Classification of Diseases (ICD). In order to demonstrate acorrelation, alinear regression model was calculated and ap-value <0.05 was considered significant. In total, 2918 cases were included over adecade starting in 2013. Out of these 776 cases were treated on an outpatient basis and two thirds of the patients were male. The patients were generally healthy with an average American Society of Anesthesiologists (ASA) status of 1.6 ± 0.6 and with apatient clinical complexity level (PCCL) of 0 in 79% of cases. Patient numbers increased continuously from 161 cases in 2013 to 393 cases in 2022 (p < 0.001). The most common main diagnosis was infectious hand diseases (L02.4-M65.14). This resulted in the most frequently assigned diagnosis-related group (DRG) being I32E (319 cases). For inpatient cases the average incision-to-suture time was 51:51 min and for outpatient cases 26:03 min. The revenue was on average 4372.90 € per inpatient case and 300.77 € per outpatient case. The rate of examinations by the German Medical Service of Health Funds (Medizinischer Dienst) was 19% over the entire observational period. The increasing case numbers in the outpatient and inpatient sectors indicate acentralization and consolidation of hand surgical expertise in the region. There are significant revenue differences between outpatient and inpatient cases.

Chatbot Demonstrates Moderate Interrater Reliability in Billing for Hand Surgery Clinic Encounters.

Artificial intelligence offers opportunities to improve the burden of health care administrative tasks. Application of machine learning to coding and billing for clinic encounters may represent time- and cost-saving benefits with low risk to patient outcomes. Gemini, a publicly available large language model chatbot, was queried with 139 de-identified patient encounters from a single surgeon and asked to provide the Current Procedural Terminology code based on the criteria for different encounter types. Percent agreement and Cohen's kappa coefficient were calculated. Gemini demonstrated 68% agreement for all encounter types, with a kappa coefficient of 0.586 corresponding to moderate interrater reliability. Agreement was highest for postoperative encounters (n = 43) with 98% agreement and lowest for new encounters (n = 27) with 48% agreement. Gemini recommended billing levels greater than the surgeon's billing level 31 times and lower billing levels 10 times, with 4 wrong encounter type codes. A publicly available chatbot without specific programming for health care billing demonstrated moderate interrater reliability with a hand surgeon in billing clinic encounters. Future integration of artificial intelligence tools in physician workflow may improve the accuracy and speed of billing encounters and lower administrative costs.

Utilization Fraction of Ambulatory Hand Procedures: Cost-Reduction Through Surgical Instrument Tray Optimization.

Our objective is to evaluate the utilization fraction (UF) of surgical instruments during a commonly performed ambulatory hand surgery case as an avenue for cost reduction, increased operating room efficiency, and systems quality improvement. The total number of instruments opened at the start of the case was recorded followed by instruments being divided into those used and not used during the procedure. Total sterile processing costs were estimated at $1.56 per instrument according to data from our institution's central sterilization processing (CSP) department. Nineteen hand procedures performed by 2 surgeons were included in this study. An average of 120.1 ± 10.9 instruments were opened at the start of each case, while an average of 12.6 ± 5.4 instruments were used per case (Figure 1). This yielded an UF of 10.7% ± 4.8%. Using our internal CSP estimate, we calculated an annual cost of $16 863 to reprocess the current hand tray (Figure 2). Using literature data, this cost ranged from $5 513 to $34 484 annually. The same cost calculations were performed for the theoretical optimized tray (incorporating instruments used at least 20% of the time when opened) containing 23.2 instruments. The annual reprocessing cost of this new tray according to CSP data was $3 260, demonstrating a cost-reduction of $13 603 or 80.7% (Figure 2). Evaluation of pre- and peri-operative processes is a valuable technique to mitigate increasing healthcare costs and reduce unnecessary healthcare spending, with broad applicability to multiple surgical subspecialties and procedures.

An Algorithm for Management of Radial Longitudinal Deficiency.

Lack of specific guidelines in the literature renders management of radial longitudinal deficiency (RLD) exceedingly diverse. This diversity in treatment approaches can lead to variability in outcomes and pose a challenge in determining the most effective interventions for each individual case of RLD. Surgeons must carefully consider the unique characteristics and needs of each patient when developing a treatment plan for this complex condition. Around 40% of cases are linked to syndromes like Holt-Oram syndrome, thrombocytopenia absent radius (TAR) syndrome, Fanconi anaemia and VACTERL. Hand surgeons must be knowledgeable about these conditions, as they may be the first to identify these syndromes in children. Associated elbow stiffness can also be a crucial factor in treatment decision-making. Although this condition has been studied for more than 10 decades, the surgical treatment that is currently available is not completely successful in restoring 'normal' wrist function and appearance. Centralisation and radialisation procedures continue to be the cornerstones of surgical treatment. Many innovative approaches include altering the biomechanics of this condition with bony or soft tissue procedures and microvascular techniques. Understanding the proximal limb changes is crucial in the holistic management of this challenging malformation. This article presents a treatment algorithm based on literature evidence and our clinical experience. Level of Evidence: Level V (Therapeutic).

Enhancing systematic review efficiency in hand surgery using artificial intelligence (natural language processing) for abstract screening.

The aim of the present study was to train a natural language processing model to recognize key text elements from research abstracts related to hand surgery, enhancing the efficiency of systematic review screening. A sample of 1600 abstracts from a systematic review of distal radial fracture treatment outcomes was annotated to train the natural language processing model. To assess time-saving potential, 200 abstracts were processed by the trained models in two experiments, where reviewers accessed natural language processing predictions to include or exclude articles. The natural language processing model achieved an overall accuracy of 0.91 in recognizing key text elements, excelling in identifying study interventions. Use of the natural language processing reduced mean screening time by 31% without compromising accuracy. Precision varied, improving in the second experiment, indicating context-dependent performance. These findings suggest that natural language processing models can streamline abstract screening in systematic reviews by effectively identifying original research and extracting relevant text elements.Level of evidence: IV.

Teaching and Practicing Congenital Hand Surgery in Cambodia - Lessons Learnt.

The global burden of surgical conditions is becoming increasingly prevalent in the developing world. Hand surgery, in particular congenital hand surgery, presents with its own challenges, particularly the unique skill sets needed, multidisciplinary nature and heterogeneity of cases. The aim of this review article is to present our experience of practising congenital hand surgery in Cambodia, and to explore the feasibility of teaching this specialty in developing countries within a meaningful and sustainable framework. Since 2013, a group of hand surgeons and therapists have visited the Children Surgical Centre in Cambodia. A community-oriented curriculum was developed following the initial visits, with analysis of data and local surgeon's skill sets. These were further refined using the Pareto analysis and selected competency procedures to develop entrustable professional activities (EPAs). Common paediatric hand cases were identified and taught to the local surgeons. Essential elements of this model include the need for measurable outcomes, clear curriculum goals, long-term partnerships and information technology support.

Ten Steps for a Successful Hand Surgery Mission Trip - Experiences from Supporting Paediatric Hand in Vietnam and Honduras.

Domestic and global access to surgical care for paediatric hand and upper limb conditions is challenged by limited resources, increasing direct and indirect costs of care and a growing number of patients who require specialty care. There are numerous barriers for patients from developing countries to receiving medical care in Japan due to the substantial costs, which include travel, uninsured medical expenses and fees imposed by intermediaries. To address this issue, I realised that I needed to take a more direct approach - by travelling to these countries, not only to provide treatment, but also to teach and train local doctors. By emphasising on the education of local clinicians through the sharing of knowledge and skills, it is possible to expand the timely access to paediatric hand surgery and improve outcomes for children in need. Our mission is rooted in the belief that every nation holds its own unique treasures - its culture, food, beauty and joy - that are worth celebrating and preserving. By fostering sustainable relationships built on mutual respect and understanding, we can make a greater impact; engagement with local surgeons will ultimately elevate the level of care that they can provide in their own communities, through improving core competencies of medical knowledge, technical/surgical skills and resource allocation for simple and complex conditions. This work not only reflects my personal commitment, but also my focus on expanding our team of fellows and strengthening organisational support. We aim to actively pursue these efforts throughout Asia, fostering cross-cultural collaboration and, ultimately, helping to heal the hands and futures of children worldwide. The aim of this review article is to share with readers how we started our mission trips to Vietnam and highlight 10 steps that I feel are critical to a successful mission trip.

A Case Report on Ellis–van Creveld Syndrome: Clinical, Embryological, Anesthetic, and Surgical Implications

AbstractPostaxial polydactyly (PAP) in the form of rudimentary soft tissue masses is quite common. Management involves ligation or surgical excision. Rarely do literature discussions cover complex variants in which the extra finger is fully developed. Ellis–van Creveld syndrome (EVC) or chondroectodermal dysplasia is a rare disorder characterized by PAP. When chondral dysplasia encompasses PAP, dwarfism, and genu valgum, ectodermal dysplasia involves nails and teeth. We describe two EVC cases. When one had cardiac malformations, the other had dental anomalies. One of them underwent genu valgum correction and removal of the additional finger. The hand surgery proved complex due to fusion of its metacarpal with the fifth metacarpal. Pediatric Outcomes Data Collection Instrument (PODCI) scores at 1.5 and 2.5 years after hand and knee surgeries were excellent. A multidisciplinary approach is essential to achieve comprehensive care. Additional embryological research is necessary to elucidate the clinical manifestations described in this report.

Hand infections : when to consult a hand surgeon ?

The hand is an anatomical site frequently affected by infection due to its central role in all daily activities. It is therefore regularly the site of wounds (contused, penetrating, insect stings, bites, etc.), all of which are potential entry points for infections. Recognition by the general practitioner of the red flags requiring an urgent specialist consultation is therefore essential in order to improve the patient's functional prognosis, determined by the initial management. In this article, we focus on the most frequent situations encountered in primary care.

Infections and Patient Satisfaction in WALANT Hand Surgery in a Hospital Procedure Room.

Background: Wide-awake hand surgery has allowed many hand procedures to be moved out of the operating room and into minor procedure rooms while increasing efficiency, maintaining safety, and reducing both patient and hospital costs. The goal of this study was to evaluate patient satisfaction and postoperative complications of wide-awake local anesthesia with no tourniquet procedures performed in a community-based hospital procedure room. Methods: A total of 786 patients underwent 948 elective hand procedures in a hospital procedure room. At the conclusion of their surgeries, the patients were surveyed regarding their satisfaction. Following surgery, patients were evaluated for postoperative complications including infections. The trend in postoperative infection rates across 8 age groups was analyzed using a Cochran-Armitage test in R. Results: The overall infection rate was 6.2% (n = 59). All infections were superficial. Carpal tunnel had the highest number of infections (n = 25), followed by trigger finger (n = 8), and the combination trigger finger with carpal tunnel (n = 7). All infections were managed with antibiotics and/or soaks. Three patients did require a return to the operating room for irrigation and debridement. Ninety-nine percent of patients said the procedure room experience was better or the same as going to the dentist, would recommend wide-awake anesthesia to a friend or family member, and would undergo the procedure again. Conclusion: Wide-awake procedures performed in a hospital procedure room have low infection rates with high patient satisfaction.

Removal of soft tissue foreign bodies in the hand under microscopy: a retrospective observational study

Purpose: Numerous studies have focused on techniques for detecting foreign bodies in soft tissue in the hand, but removal remains a subject of interest. In this study, we describe the microscope-assisted removal of foreign bodies in the hand. Methods: We reviewed records of patients treated for foreign bodies in the hand at our department from July 2013 to May 2023. In 16 patients aged 23 to 55 years, the following variables were analyzed: the cause of trauma; the time interval from trauma to surgery; the location, type, size, and number of foreign bodies; patient complaints; imaging technique; and procedure type. Under local anesthesia, a slit incision was made at the suspected site. Foreign bodies were completely removed using micro-instruments under microscopic guidance. Results: Stab injuries were the most common (n=13), and there was one case each of abrasion, traffic accident, and bee sting. The middle finger (n=5) was the most affected, followed by the thumb (n=4), index (n=3), little finger (n=2), ring finger (n=1), and palm (n=1). Foreign bodies included glass (n=6), wood (n=4), seashell (n=2), fish bone, a pencil tip, a bee stinger, and metal. Their size ranged from 1 to 20 mm. Patient complaints included a foreign body sensation, localized pain, swelling, discoloration, and a skin lesion. X-ray examinations were performed in all cases, and ultrasonography was conducted in five cases. Conclusion: A microscopic approach allows precise, safe, and complete removal of foreign bodies without tissue damage, highlighting the efficacy of this technique in hand surgery.

Publishing during a Pandemic: Analyzing Recent Publication Times in Hand Surgery.

Timely distribution of research is crucial for improving treatments and patient care; however, the publication process is historically unhurried. The primary goal of this study was to analyze the time to publication in hand surgery for 5 years and to examine potential factors affecting publication speed. A 5-year review (2017-2021) was performed on 4 major hand surgery journals. The Journal of Hand Surgery American Volume, Journal of Hand Surgery European Volume, Journal of Plastic Surgery and Hand Surgery, and Plastic and Reconstructive Surgery were included in the review. Differences were assessed using analysis of variance or 2-sided independent t tests for continuous variables. There was a significant difference in submission-to-publication time between journals (P < 0.001). This differed by year (P < 0.001), with a significant increase in time from submission to publication after 2019, during the COVID-19 pandemic (447 ± 198 versus 406 ± 169 d, P < 0.001). Geographic region of the primary institution did affect submission-to-publication time (P < 0.001). No significant difference was seen in submission-to-publication time based on the number of institutions contributing, article type, or first author or corresponding author surgical specialty (P > 0.05). Time to publication in hand surgery varies by hand surgery journal and significantly increased during the COVID-19 pandemic. New research reflects work done over a year ago at least. Participation in the peer-review process should be encouraged and bolstered within the hand surgery community to improve research dissemination times within the field.

Utilization of Surgical Fixation for Distal Radius Fractures in the United States: A Population-Based Cohort Study

In contrast to younger adult populations, clinical practice guidelines state that there is no difference in long-term functional outcomes in surgically versus nonoperatively treated distal radius fractures in patients ≥65 years old. In this study, we asked the following questions: (1) has treatment for distal radius fractures in younger and older adult populations changed over time? (2) What patient and surgeon factors are associated with treatment trends? Using a national administrative claims database, we identified patients aged ≥18 years with isolated, closed distal radius fractures, subdivided by age (18-64 years, ≥65 years old). We characterized the proportion of patients who underwent open reduction and internal fixation (ORIF) over time. We stratified our analysis by surgeon subspecialty, region, and mean area income. Changes in ORIF utilization over time were evaluated using linear regression models. The proportion of distal radius ORIF, including in patients aged ≥65 years, increased from 10.4% in 2012 to 15.1% in 2020. Of the ORIF procedures performed, hand surgeons accounted for an increasing proportion over time, with a corresponding decrease in those performed by general orthopedic surgeons. The proportion of ORIF increased over time in all US regions, with the largest rate of increase in the Midwest for patients aged ≥65 years and Northeast for patients aged 18-64 years. Patients living in areas with mean family income ≥$65,000 were more likely to undergo ORIF. The proportion of distal radius ORIF including in older adult populations is increasing in all US regions, and an increasing proportion is performed by hand surgeons. Further analysis of the drivers of these trends is warranted, given the rising incidence of surgical treatment in older patients, which could reflect evolving patient activity demands and suggest a need to further evaluate conventional treatment algorithms based on age.

The Ten Test and Sensory Evaluation of Hand and Finger Injuries in the Emergency Department

BackgroundHand and finger injuries are a common presenting complaint to the emergency department and are associated with significant morbidity. Neurologic evaluation of these injuries is a crucial component of the patient assessment and can be done via a variety of testing methods. DiscussionWhile most taught and cited in the emergency department literature, the two-point discrimination (2PD) test for sensation has several drawbacks, including limited reproducibility and reliability. While often utilized by hand surgical specialists, the Semmes-Weinstein monofilament (SWM) test and the Weinstein Enhanced Sensory Test (WEST) are not practical for the emergency physician due to the need for specialized equipment and frequent calibration. The ten test, a relatively new sensory evaluation method, has been shown to be reliable, reproducible, and pragmatic in varying types of clinical environments. ConclusionThe ten test is a pragmatic alternative method of evaluation to two-point that is utilized by specialists in hand surgery and injuries. The emergency physician should consider adding the ten test to their evaluation and reporting of hand and finger injuries in the emergency department.

Anatomical variations in 3D imaging: a case report of a dorsal metacarpal artery anomaly

This report presents a novel anatomical variant of the second dorsal metacarpal artery (SDMA). In this unique case, the SDMA abnormally penetrates the second dorsal interosseous muscle (SDIM), dividing into two major branches. A deep dorsal branch of the SDMA (dbSDMA) is located within the SDIM and extends to the distal end of the metacarpal. The other branch forms a perforating branch called the P-SDMA, which anastomoses with the palmar metacarpal artery branch (PMAb) and the deep palmar arch branch (DPAcb) in the deep palmar area. The discovery of this SDMA variant is significant for procedures involving complex hand surgeries such as DMA flaps. Understanding this anatomical variation is crucial for accurate surgical planning and can help avoid potential complications during surgery. To elucidate these unique variations, we employ three-dimensional (3D) imaging techniques, demonstrating the potential of these technologies to advance the visualization of anatomical structures and enhance medical education. 3D imaging also facilitates augmented reality applications and 3D printing. Our findings underscore the possible applications of 3D imaging in medical practice and education, potentially transforming anatomy education and surgical planning.

Bone Graft and Fixation Options in the Surgical Management of Scaphoid Nonunion.

Scaphoid nonunions are a complex challenge that are frequently encountered by hand surgeons. Because of the tenuous blood supply of the scaphoid and secondary deformities that occur as a result of delayed or unsuccessful treatment, the treatment of scaphoid nonunions frequently requires the use of internal fixation and supplemental bone graft. There are multiple bone graft sources and techniques that can be employed based on the patient, the viability of the proximal pole fragment, and the presence of a deformity. Without osteonecrosis or disruption of the scaphoid blood supply, nonvascularized autologous grafts can be used from the distal radius, proximal ulna, or iliac crest. In cases where there is concern for an insufficient blood supply, vascularized bone graft sources can be employed, including pedicled local grafts and free flap grafts. When there is a nonviable and fragmented proximal pole, using osteochondral autografts has become increasingly used to reconstruct the scaphoid. Bone graft substitutes can additionally be used to supplement the fixation construct. This review focuses on the indications and role of bone grafts in scaphoid nonunions to help augment internal fixation, promote healing, and restore carpal alignment.

Intraoperative Cost Comparison of Endoscopic Carpal Tunnel Release With WALANT Versus MAC Anesthesia.

The cost of endoscopic carpal tunnel release (ECTR) has historically been shown to be significantly higher than the cost of open carpal tunnel release (OCTR). Setting and anesthetic technique drive costs in hand surgery; ambulatory surgical center (ASC) settings demonstrate lower costs when compared to hospital-based settings and local-only anesthetic techniques demonstrate savings over general anesthesia. The purpose of this study is to compare wide awake local-only anesthesia technique (WALANT) to monitored anesthetic care (MAC) for ECTR performed in an ASC setting. This study includes 481 ECTR under WALANT and 405 ECTR under MAC, performed between January 2019 and December 2021 in an ASC. Utilizing previously reported direct operating room costs, overhead, and material costs, we calculated a final cost for each procedure. We also report our complication rates: intraoperative conversion to OCTR and late revision to OCTR. Intraoperative times were shortest for ECTR performed under WALANT (22 min) versus ECTR under MAC (25 min). The total cost for ECTR under WALANT was most cost-effective at $1341.28 versus ECTR under MAC at $1634.00. Both techniques demonstrated a low complication profile. Our intraoperative process flow, staffing model, and ASC setting resulted in cost savings making ECTR an economically feasible option.

Hand surgery in Vietnam: development, challenges and future directions.

Hand surgery in Vietnam has evolved significantly, especially in cities like Ho Chi Minh City, Hanoi and Hue. Despite advancements, there remain challenges, including the lack of a unified national hand surgery society. This article highlights the contributions of key figures, advances and the future of the discipline in the country.
