Purpose

Due to the Coronavirus Disease-19 pandemic, the fellowship application process has transitioned from in-person interviews to virtual interviews. Although several studies have assessed the impact of Coronavirus Disease-19 on residency and fellowship interviews, fewer studies have investigated the program director’s perspective. Therefore, the aim of this study was to assess the experience of virtual interviews on hand fellowship program directors and understand some of the important factors that may make an applicant more competitive.

Methods

A 21-question survey was conducted through Google Forms and distributed through a standardized email to hand fellowship program directors and coordinators. Questions used a 5-point Likert scale with the opportunity for respondents to answer some questions in a free-response format. Statistical analysis was conducted with significance assigned to P values < .05.

Results

Ninety-three surveys were distributed, of which 35 responses were obtained, corresponding to a 37.6% survey response rate. Program directors reported that they tended to place more emphasis on applicant’s curriculum vitae, calls from colleagues, and applicants that they had previously met. In addition, program directors felt that applicants were able to accurately represent themselves through the virtual format. Finally, most program directors stated that they were highly likely to continue to offer virtual interviews.

Conclusions

With several parenting organizations and program directors affirming that they are comfortable with proceeding with virtual interviews, it is essential for hand fellowship applicants to understand what factors program directors may perceive as more important. It is possible that the virtual interview process may effectively achieve suitable matches between applicants and institutions.

Decision analysis IIIb.

Purpose

The integration of artificial intelligence and machine learning technologies into the medical field has brought about remarkable advancements, particularly in the domain of clinical decision support systems. However, it is uncertain how they will perform as clinical decision-makers.

Methods

This prospective cohort study evaluates the potential of incorporating ChatGPT-4 plus into the management of subcapital fifth metacarpal fractures. The treatment recommendations provided by ChatGPT-4 plus were compared with those of the two control groups—the attending clinic plastic surgeon and an independent expert panel. The primary outcome measures, operative or conservative, were compared between the groups. Intraclass correlation of 0.61 infers moderate reliability in the consistency of recommended management plans across all groups.

Results

Key predictors for opting for operative management, regardless of the decision-maker, included clinical signs of scissoring, extension deficit, and radiographic evidence of intra-articular extension.

Conclusions

These findings support the potential for artificial intelligence applications in enhancing diagnostic and treatment decisions.

Therapeutic IV.

Purpose

Distal radius fractures (DRF) are among the most commonly encountered fractures. The population of the United States is rapidly growing, aging, and diversifying. This study was undertaken to better understand current incidences and treatment trends across all ages, gender, and races to inform resource allocation and to potentially address treatment inequities.

Methods

The TriNetX US Collaborative Network was queried for all patients diagnosed with DRFs from 2017 to 2022. Cohorts were defined by inclusion and exclusion of Current Procedural Terminology procedure codes and categorized into operative and nonsurgical groups. Statistical analysis was performed to determine differences in management among demographic groups across the 6-year time period.

Results

Incidence rates of operative intervention for DRF increased from 19.6% in 2017 to 23.6% in 2022. Incidence rates of operative intervention increased from 21.7% to 25.2% for females and from 15.3% to 19.7% for males. A bimodal distribution was observed in females with more fractures occurring in the pediatric and geriatric ages, but this distribution was not observed in males. All demographic groups had an overall higher incidence of nonsurgical intervention. Patients aged 40–64 years were more likely to undergo operative intervention than patients 18–39 years. Females were more likely to undergo operative intervention than males. White patients were more likely to undergo operative intervention than Black patients and Asian patients.

Conclusions

The incidence of DRFs continues to climb, as does their rate of operative management. The classic bimodal distribution was observed in females, but not males. However, differences in management of DRFs were also observed across different demographic groups with ongoing racial disparities. Future consideration should be taken into optimizing treatment disparities relative to demographic status.

Purpose

The placement of multistrand sutures during flexor tendon repair is complex and challenging. We developed a new, simpler, nine-strand suture, which we term the Tajima nines. The Tajima nines repair method is a new odd-numbered strand tendon technique.

Methods

Fourteen porcine flexor tendons were transected and repaired using the Tajima nines repair method, without placement of peripheral sutures. This technique is a modification of the Lim and Tsai repair method; it uses a 4-0 monofilament nylon, 3-strand line, and two needles. The repaired tendons were tested for linear, noncyclic, load-to-failure tensile strength. The initial gap, 2-mm gap-formation force, and ultimate strength were measured.

Results

The initial gap-formation force was 27.9 ± 7.5 newtons (N), the 2-mm gap-formation force was 39.2 ± 4.7 N, and the ultimate strength was 76.7 ± 17.2 N. Eight, three, and three of the 14 tendons repaired using the Tajima nines method demonstrated failure because of thread breakage, knot failure, and suture pull-out, respectively.

Conclusions

This biomechanical study demonstrated that Tajima nines repair was associated with particularly high initial tension at the repair site; there were minor variations in the initial load and 2-mm gap-formation load. Our results suggest that Tajima nines repair with peripheral suturing allows the repaired flexor tendon to tolerate the stresses encountered during early active mobilization.

Clinical relevance

This simple nine-strand technique will be particularly useful for inexperienced surgeons who perform early active mobilization after primary flexor tendon repair because the technique is a modification of the Lim and Tsai repair method using a triple strand instead of a double strand.

Treatment of children with upper-extremity trauma, congenital hand differences, cerebral palsy, and brachial plexus birth injuries requires specialized training, given the spectrum of pathology and complexities of treating an individual who is still developing. Although a limited number of dedicated pediatric hand surgery fellowships are available, mastering the large breadth of the field should ideally begin early in training and may take several different pathways. The authors seek to provide a comprehensive list of resources for trainees interested in pediatric hand surgery, including training opportunities, educational tools, and networking organizations. By shining a light on these pediatric hand surgery resources, we hope to encourage future trainees to plan ahead, so that they are well-prepared for the care of children with complex upper limb reconstructive needs.

Metastatic hand tumors are uncommon but important to include in the differential diagnosis for hand masses. In this study, we report the case of a patient presenting initially with hand pain and swelling with no other pertinent medical history except for an extensive smoking history. Subsequent mass biopsy and work-up revealed metastatic lung cancer. Acral metastases to the hand as the first manifestation of a primary tumor are a rare but debilitating condition with a poor prognosis. Hand surgeons must remain aware of the potential for metastatic hand tumors in patients without known malignancy and advocate for the prompt initiation of multidisciplinary care and treatment to maximize patient outcomes.

Rotator cuff arthropathy is a spectrum of disease states secondary to full-thickness cuff tears classified by rotator cuff insufficiency and degenerative disease within the shoulder joint. Diagnosis can be made through standard physical exam and radiographic films demonstrating varying levels of weakness, along with acetabularization, femoralization, and superior migration of the humeral head. Severity of disease is classified through both the Hamada and Seebauer grading systems, which are used clinically to determine the appropriate treatment algorithm. Treatment exists along the spectrum from conservative therapy with physical therapy to a definitive treatment with total joint replacement. Depending on a patient’s progression and other comorbidities, arthroscopic treatments may additionally be used in specific circumstances as joint-sparing techniques. In recent years, reverse total shoulder arthroplasty has produced increasingly favorable outcomes with improvements in pain and function while simultaneously diminishing complication rates, making it generally accepted as standard of care. This disease limits quality of life for a large population of patients and efforts toward optimization of the treatment regimen is critical. This review provides an overview on the diagnostic criteria, classification, pathoanatomic changes, biomechanics, treatment options, outcomes, and complications of rotator cuff arthropathy.

Purpose

Pediatric trigger thumb is a common condition resulting in referral from primary care to specialty care. Access to pediatric hand specialty care is a complex issue influenced by a multitude of social factors, including socioeconomic status. The aim of this study is to investigate the relationship between area deprivation and the time from primary care referral to presentation to specialty care for pediatric trigger thumb.

Methods

Participants were pediatric patients with trigger thumb. Patient-level area deprivation was reflected by the area deprivation index (ADI). We analyzed the relationship of the ADI to patient demographics (age and sex), trigger thumb treatment (surgical vs nonsurgical), and time to initial hand surgical visit after referral and surgical management when indicated.

Results

Among 163 patients with trigger thumb, 52% were men. Mean age at referral for trigger thumb was 2.9 ± 1.7 years. Mean ADI for patients diagnosed with trigger thumb was 57.8 ± 23.4 for the 2018 data set and 57.3 ± 23.6 for the 2021 data set, on a scale of 1 (low) to 100 (high). The median time from referral from primary care to presentation to orthopedic care for trigger thumb was 34 days. Upon presentation to treating hand surgeon, 118 patients (72.4%) underwent surgical release. We found no difference in ADI between men and women nor between patients treated operatively or with nonsurgical management. We found a weak positive correlation between ADI and time from initial referral to presentation to the treating hand surgeon. There was no correlation between ADI and time from initial hand surgical evaluation and surgical management in patients indicated for surgery.

Conclusions

Pediatric trigger thumb patients from areas with higher ADI have a slightly longer delay between initial referral and their initial visit with an orthopedic hand specialist. Although we found a delay in initial evaluation by the treating hand surgeon in patients with higher ADI, ADI status was not different between patients managed with surgical and nonsurgical treatment nor between men and women.

Clinical relevance

Neighborhood ADI weakly correlated with increased time from referral to accessing specialty orthopedic care for trigger thumb. This may suggest a need for more equitable access to specialty care for patients with pediatric trigger thumb from high ADI areas.

We present two cases of complex metacarpal fractures treated with an intramedullary locking nail. This is an emerging fixation method that minimizes tissue insult, provides sufficient stability, and allows early mobilization. Locking nails accommodate the capture of fractured fragments in complex unstable patterns and provide longitudinal and rotational stability. The described intrafocal technique is intended to improve coaxial placement of the wire into the medullary canal.
