Influences of Repair Site Tension and Conduit Splinting on Peripheral Nerve Reconstruction

BACKGROUND

We investigated the use of a conduit splinting technique to mitigate tension at the coaptation site of a rodent nerve defect model to determine the optimal reconstruction method for segmental nerve defects.

METHODS

A rat sciatic nerve segmental defect model was created by excising 5mm of the sciatic nerve unilaterally. Four groups of 10 rats were each reconstructed using 1 of 4 techniques: primary repair, repair with conduit splinting, reverse isograft with conduit splinting, and reverse isograft without splinting. Functional outcomes were assessed at 6 weeks by measurement of Sciatic Functional Index (SFI), and sciatic nerves were harvested at the nonsurvival surgery. Histomorphologic measurements were reported as a value normalized to the average measurements of the control side. The primary outcomes were assessment of nerve continuity and the proportion of nerve fibers in the regenerating nerve compared with the uninjured side.

RESULTS

The number of repair site rupture rates was lower when a conduit splint was used-less than half of the primary repairs under tension remained intact at 6 weeks. No difference was seen in axon number, size, and density between primary repairs and those augmented by conduit splints, but worse functional outcomes and more debris were present compared with the intact primary repairs.

CONCLUSIONS

Nerve conduit splinting reduced rupture rates, particularly for nerve repairs associated with a segmental defect. No significant difference was seen in the number of axons among techniques. Primary nerve repair under tension that did not rupture demonstrated superior SFI.

Future Considerations in the Diagnosis and Treatment of Compressive Neuropathies of the Upper Extremity

Compressive neuropathies of the upper extremity are among the most common conditions seen by hand surgeons. The diagnoses of carpal tunnel syndrome and cubital tunnel syndrome have traditionally been made by a combination of history, physical examination, and electrodiagnostic testing. However, findings can be nonspecific and electrodiagnostic testing is invasive for the patient. The diagnosis of compressive neuropathies continues to evolve as technology advances, and newer diagnostic modalities predominantly focus on preoperative diagnostic imaging with ultrasound and magnetic resonance imaging/neurography. With the advent of cheaper, faster, and less invasive imaging, the future may bring a paradigm shift away from electrophysiology as the gold standard for the preoperative diagnosis of compressive neuropathies. Intraoperative imaging of nerve health is an emerging concept that warrants further investigation, whereas postoperative imaging of nerve recovery with ultrasound and magnetic resonance imaging currently has a limited role because of nonspecific findings and potential for misinterpretation. Advances in surgical treatment of compressive neuropathies appear to center around the use of imaging for less invasive neurolysis techniques and other adjunctive treatments with nerve decompression. The management of failed peripheral nerve decompressions and recurrent compressive neuropathies remains challenging.

Trial of ultrasound guided carpal tunnel release versus traditional open release (TUTOR)

BACKGROUND

Carpal tunnel release (CTR) is a surgical treatment option for patients with carpal tunnel syndrome (CTS) symptoms that are unresponsive to conservative treatment. Most patients experience symptomatic relief after CTR regardless of the surgical technique. However, direct comparisons of the safety and effectiveness between CTR surgical techniques are limited. The purpose of this randomized controlled trial is to compare the safety and effectiveness of CTR with ultrasound guidance (CTR-US) versus mini-open CTR (mOCTR) in subjects with symptomatic CTS.

DESIGN AND METHODS

TUTOR (Trial of Ultrasound guided CTR versus Traditional Open Release) is a randomized controlled trial in which 120 subjects at up to 12 sites in the United States will be randomized (2:1) to receive CTR-US or mOCTR. The primary endpoint of the study is the percentage of patients who return to normal daily activities within 3 days of the procedure. Secondary endpoints of the study are median time to return to normal daily activities, percentage of patients who return to work within 3 days of the procedure, median time to return to work, Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) change score at 3 months, BCTQ Functional Status Scale (BCTQ-FSS) change score at 3 months, Numeric Pain Scale change score at 3 months, EuroQoL-5 Dimension 5-Level (EQ-5D-5L) change score at 3 months, and the incidence of device- or procedure-related adverse events at 3 months. Patient follow-up in this trial will continue for 1 year.

ETHICS AND DISSEMINATION

This study was approved by a central institutional review board and ongoing trial oversight will be provided by a data safety monitoring board (DSMB). The authors intend to report the results of this trial at medical conferences and peer-reviewed journals. The outcomes of TUTOR will have important clinical and economic implications for all stakeholders involved in treating patients with CTS.

A system for automated acquisition of digital flexion using a 3-D camera and custom gantry

Introduction

Automated measurement of digital range of motion (ROM) may improve the accuracy of reporting and increase clinical efficiency. We hypothesize that a 3-D camera on a custom gantry will produce ROM measurements similar to those obtained with a manual goniometer.

Methods

A 3-D camera mounted on a custom gantry, was mechanized to rotate 200° around a platform. The video was processed to segment each digit and calculate joint angles in people with no history of any hand conditions or surgery to validate the system. A second-generation prototype was then assessed in people with different hand conditions. Metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint flexion were measured repeatedly with a goniometer and the automated system. The average difference between manual and automatic measurements was calculated along with intraclass correlation coefficients (ICC).

Results

In the initial validation, 1,488 manual and 1,488 automated joint measurements were obtained and the measurement algorithm was refined. In people with hand conditions, 688 manual and 688 automated joint measurements were compared. Average acquisition time was 7 s per hand, with an additional 2-3 s required for data processing. ICC between manual and automated data in the clinical study ranged from 0.65 to 0.85 for the MCP joints, and 0.22 to 0.66 for PIP joints.

Discussion

The automated system resulted in rapid data acquisition, with reliability varying by type of joint and location. It has the potential to improve efficiency in the collection of physical exam findings. Further developments of the system are needed to measure thumb and distal phalangeal motions.

Team Approach: Management of Brachial Plexus Injuries

»

Traumatic brachial plexus injuries are relatively rare but potentially devastating injuries with substantial functional, psychological, and economic consequences.

»

Prompt referral (ideally within 6 weeks of injury) to a center with a team of experts experienced in the diagnosis and management of these injuries is helpful to achieving optimal outcomes.

»

Preoperative and intraoperative decision-making to diagnose and plan reconstructive procedures is complex and must take into account a number of factors, including the time from injury, concomitant injuries, preservation of cervical nerve roots, and the availability of intraplexal and extraplexal donor nerves for nerve transfer.

»

A team approach is essential to ensure accurate localization of the pathology before surgery and to maximize rehabilitation after surgery, necessitating close contact between the surgical team, physiatrists, radiologists, and therapists.

Surgical Treatment of Foot Drop: Pathophysiology and Tendon Transfers for Restoration of Motor Function

Foot drop is a common condition that may impact physical function and health-related quality of life. A detailed clinical history and physical examination are critical components of the initial evaluation of patients presenting with foot drop. Patients with refractory foot drop without spontaneous recovery of motor deficits, delayed presentation greater than 12 months from injury, or neural lesions that are not amenable to or have failed nerve reconstruction may be candidates for tendon transfers to restore active ankle dorsiflexion. The modified Bridle procedure is a dynamic tendon transfer that has demonstrated excellent functional outcomes in patients with refractory foot drop.

Optimizing the Virtual Interview Experience for Hand Surgery Fellowships

Similar to many other medical training programs, fellowship interviews for hand surgery will be conducted virtually for a second consecutive year. We provide strategies for applicants to ideally portray themselves and to learn about fellowship programs. We include approaches for fellowship programs to identify candidates that match their values as a program, as well as ways to provide useful information to applicants about the program's culture. Given that components of virtual interviewing and recruitment will likely be an ongoing part of fellowship applications, we hope this article provides a framework to guide both applicants and program faculty for the 2021 to 2022 cycle and beyond.

Surgical Treatment of Foot Drop: Patient Evaluation and Peripheral Nerve Treatment Options

Foot drop is a common clinical condition which may substantially impact physical function and health-related quality of life. The etiologies of foot drop are diverse and a detailed history and physical examination are essential in understanding the underlying pathophysiology and capacity for spontaneous recovery. Patients presenting with acute foot drop or those without significant spontaneous recovery of motor deficits may be candidates for surgical intervention. The timing, mechanism, and severity of neural injury resulting in foot drop influence the selection of the most appropriate peripheral nerve surgery, which may include direct nerve repair, neurolysis, nerve grafting, or nerve transfer.

An Epidemic Amidst a Pandemic: Musculoskeletal Firearm Injuries During the COVID-19 Pandemic

BACKGROUND

The COVID-19 pandemic has substantially impacted the delivery of health care, both through direct care associated with COVID-19 and through more pervasive effects. Our goal was to evaluate whether the number of orthopaedic consultations for firearm injuries differed during the early months of the COVID-19 pandemic compared with the same period in prior years. We hypothesized that the initial months of the COVID-19 pandemic, compared with the same period in prior years, would have a higher number of orthopaedic consultations for firearm injuries and a lower rate of outpatient follow-up after consultations.

METHODS

A prospectively collected database of orthopaedic trauma consultations at a level-I trauma center was queried for firearm injuries. We compared the number of orthopaedic consultations for firearm injury during the initial months of the COVID-19 pandemic (March 23, 2020, to September 30, 2020, referred to as the pandemic group) with identical dates from 2017 to 2019 (referred to as the pre-pandemic group). Outpatient follow-up rates, ZIP codes (and associated Area Deprivation Index), and demographic data were compared between the pandemic group and the pre-pandemic group.

RESULTS

During the entire study period, 552 orthopaedic consultations for firearm injuries were identified. There was a 63% increase in the daily mean number of firearm injury consultations in the pandemic group, to 1.01, compared with the pre-pandemic group, 0.62 (p < 0.001). There was no difference in the rate of outpatient follow-up: 66% for the pandemic group and 72% for the pre-pandemic group. There was no difference in the percentage of patients from the most socially deprived decile: 45.3% in the pandemic group and 49.5% in the pre-pandemic group. Patients presenting during the pandemic were more often uninsured (75.8%) relative to the pre-pandemic group (67.9%), with a lack of health insurance significantly decreasing the likelihood of outpatient follow-up (p < 0.01).

CONCLUSIONS

Compared with the same period in prior years, there was a significant increase in the number of orthopaedic consultations for firearm injuries during the early months of the COVID-19 pandemic in our community. Patient race, socioeconomic status, and outpatient follow-up were similar between the pandemic group and the pre-pandemic group. There was a higher proportion of uninsured patients within the pandemic group and a lower rate of follow-up among those without insurance.

Moving the Needle: Directed Intervention by the American Society for Surgery of the Hand Is Effective in Encouraging Diversity in Expert Panel Composition

Purpose

Recent efforts have been made by the American Society for Surgery of the Hand to encourage female inclusion in expert panels. We hypothesized that female representation on expert panels has increased over the past decade and that a directed intervention by the American Society for Surgery of the Hand would be associated with an increased percentage of submissions with female panelists.

Methods

We performed a retrospective analysis of Instructional Course Lecture and Symposium submissions for the 2011 through 2021 American Society for Surgery of the Hand Annual Meetings. Authorship was reviewed, and the gender of the proposed authors was recorded. Additionally, the status of “all-male panel” was attributed to panels with no proposed female authors. Submissions were reviewed and compared with meeting programs to determine the status of accepted or rejected. Longitudinal analysis was performed to determine trends in the gender composition of expert panels.

Results

In total, 1,687 submissions were reviewed, including 1,323 Instructional Course Lectures and 364 Symposia. Female authorship constituted 18% of authorship (1,170/6,663), and lead authorship was similarly distributed, with 18% being female (296/1,687). Overall, female representation has increased steadily over the past decade, with females constituting 13% (43/332) and 20% (163/818) of the submitted authors in 2011 and 2020, respectively. Similarly, all-male panels declined from 74% (76/103) to 46% (85/185) of panels over the same timeframe. Most strikingly, a sharp increase in gender representation was observed with the directed intervention noted in the 2021 Call for Abstracts, resulting in an increase in female authorship to 26% (295/1,124) and a decline in all-male panels to 29% (70/241).

Conclusions

Gender representation among hand surgery expert panels moved toward increased equity over the past decade, which has been aided by directed interventions.

Clinical relevance

Career development and trainee decision making are impacted by gender representation; directed and intentional interventions by professional organizations are effective in encouraging greater equity and diversity within the field.

Histologic and Functional Outcomes of Conduit Wrapping for Peripheral Nerve Repair: Early Results in a Rat Model

BACKGROUND

 The concept of utilizing a nerve conduit for augmentation of a primary nerve repair has been advocated as a method to prevent neural scarring and decrease adhesions. Despite clinical use, little is known about the effects of a nerve conduit wrapped around a primary repair. To better understand this, we investigated the histologic and functional effects of use of a nerve conduit wrapped around a rat sciatic nerve repair without tension.

METHODS

 Twenty Lewis' rats were divided into two groups of 10 rats each. In each group, unilateral sciatic nerve transection and repair were performed, with the opposite limb utilized as a matched control. In the first group, direct repair alone was performed; in the second group, this repair was augmented with a porcine submucosa conduit wrapped around the repair site. Sciatic functional index (SFI) was measured at 6 weeks with walking track analysis in both groups. Nonsurvival surgeries were then performed in all animals to harvest both the experimental and control nerves to measure histomorphometric parameters of recovery. Histomorphometric parameters assessed included total number of neurons, nerve fiber density, nerve fiber width, G-ratio, and percentage of debris. Unpaired t-test was used to compare outcomes between the two groups.

RESULTS

 All nerves healed uneventfully but compared with direct repair; conduit usage was associated with greater histologic debris, decreased axonal density, worse G-ratio, and worse SFI. No significant differences were found in total axon count or gastrocnemius weight.

CONCLUSION

 In the absence of segmental defects, conduit wrapping primary nerve repairs seem to be associated with worse functional and mixed histologic outcomes at 6 weeks, possibly due to debris from conduit resorption. While clinical implications are unclear, more basic science and clinical studies should be performed prior to widespread adoption of this practice.

"This New Chapter of Life": Content Analysis of Facebook Posts After Traumatic Brachial Plexus Injury

Background: After traumatic brachial plexus injuries (BPI), the sudden loss of physical function is often accompanied by psychological distress. Given the complex nature and relative infrequency of the injury, BPI patients will often use online resources for information about their injury as well as emotional support. Questions/Purpose: Recognizing the influence of social media, we sought to search a popular social media platform to identify challenges faced by BPI patients and strategies used to overcome these challenges. Methods: We searched "traumatic brachial plexus injury" on Facebook and selected the 2 most popular BPI support groups. We collected posts regarding traumatic BPI from November 1, 2018 through November 1, 2019. We performed inductive and deductive thematic analysis of the posts to identify recurring topics, knowledge gaps, and peer interaction dynamics. Results: We analyzed 7694 posts from the 2 Facebook support groups. The following themes emerged: (1) BPI patients express discontent regarding the inability to use their arm and the slow or stagnant pace of recovery; (2) BPI patients are frustrated over their inability to retain their preinjury livelihood; and (3) BPI patients emphasize that acceptance and moving on are key components of adjustment to their condition. Some patients described the role of limb amputation in achieving these goals. Conclusions: Our analysis demonstrates the areas in which BPI patients are in need of emotional support. Adjustment to BPI might be facilitated through multidisciplinary care that addresses emotional aspects of recovery and emphasizes self-management skills, in addition to the traditional focus on physical function.

Interpretation of Electrodiagnostic Studies: How to Apply It to the Practice of Orthopaedic Surgery

Electrodiagnostic studies may help orthopaedic surgeons to identify and confirm nerve pathology, determine severity of disease, localize the lesion, identify concomitant or alternative pathology, and prognosticate potential outcomes with nonoperative or operative treatment. Surgeons should recognize the indications for electrodiagnostic studies, principles of their performance, and how to assess the primary data generated by the examination and how it can inform their treatment plans.

Development and Testing of a Novel Locking Pin Cap to Create a Fixed-Angle K-Wire Plate Construct

PURPOSE

To test the effectiveness of a novel locking pin cap to attach a K-wire rigidly to a volar locking plate and resist fracture displacement compared with commercially available alternatives.

METHODS

Two different methods of fracture fixation were tested on a total of 12 Sawbones models with volar shear distal radius fracture (6/group). The fragments were fixed with either 2 commercially available pin plates (industry standard) or a volar plate with 2 locking screws fixing the scaphoid facet and 2 pins locked to the plate with a novel locking pin cap in the lunate facet. Axial load conditioning was performed followed by sinusoidal loading to 250 N at 50 mm/s. A motion capture system was used to assess the relative movement of the fracture fragments relative to the intact shaft. The strength of the fixation construct was quantified by (1) the force required to achieve a 2-mm gap between the shaft and fracture fragments and (2) ultimate load to failure.

RESULTS

One industry standard pin plate demonstrated disassociation of the pin from the plate after fatigue conditioning. This did not occur in the locking pin cap group. The locking pin cap construct group was able to sustain a significantly higher load compared with the industry standard when the construct was displaced to the 2-mm gap. The locking pin cap also significantly increased the ultimate load to failure compared with the industry standard.

CONCLUSIONS

The novel locking pin cap creates a fixed-angle attachment of a K-wire to an existing locking screw hole in a plate. This fixed-angle K-wire is significantly stronger in preventing gap formation and resisting ultimate failure than commercially available plates that use bent K-wires.

CLINICAL RELEVANCE

The development of novel techniques to secure small articular fragments may ultimately improve clinical outcomes.

Current Concepts Review: Common Peroneal Nerve Palsy After Knee Dislocations

Dislocation of the native knee represents a challenging injury, further complicated by the high rate of concurrent injury to the common peroneal nerve (CPN). Initial management of this injury requires a thorough neurovascular examination, given the prevalence of popliteal artery injury and limb-threatening ischemia. Further management of a knee dislocation with associated CPN palsy requires coordinated care involving the sports surgeon for ligamentous knee reconstruction and the peripheral nerve surgeon for staged or concurrent peroneal nerve decompression and/or reconstruction. Finally, the foot and ankle surgeon is often required to manage a foot drop with a distal tendon transfer to restore foot dorsiflexion. For instance, the Bridle Procedure-a modification of the anterior transfer of the posterior tibialis muscle, under the extensor retinaculum, with tri-tendon anastomosis to the anterior tibial and peroneus longus tendons at the anterior ankle-can successfully return patients to brace-free ambulation and athletic function following CPN palsy. Cross-discipline coordination and collaboration is essential to ensure appropriate timing of operative interventions and ensure maintenance of passive dorsiflexion prior to tendon transfer.

Increased Utilization of Total Joint Arthroplasty After Medicaid Expansion

BACKGROUND

The expansion of state Medicaid programs under the U.S. Affordable Care Act has led to a dramatic increase in the number of Americans with health insurance coverage. Prior analyses of a limited number of states have suggested that greater utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) should be expected after Medicaid expansion. The purpose of our study was to examine whether increased utilization of THA and TKA occurred across a broader range of states after Medicaid expansion.

METHODS

We analyzed administrative data from the Healthcare Cost and Utilization Project from 9 states (Arkansas, Arizona, Colorado, Iowa, Massachusetts, Maryland, Nevada, New York, and Vermont) that expanded Medicaid in 2014 and 2 states that did not expand Medicaid (Florida and Missouri). We included patients who were 18 to 64 years of age and had a primary THA or TKA from 2012 to 2015 with Medicaid as the primary payer. Other payers (including dual-eligible Medicaid and Medicare beneficiaries) were excluded. We performed multivariable regression modeling with the number of Medicaid-insured THAs or TKAs as the dependent variable and the interaction between the state Medicaid expansion status and year as the main policy independent variable, with adjustment for community characteristics.

RESULTS

Among all 11 states, there were 39,452 total joint arthroplasties (42% THA and 58% TKA) funded by Medicaid from 2012 to 2015. After adjusting for community characteristics, within expansion states, compared with 2013, THA and TKA increased 15% in 2014 (p < 0.0001) and 23% in 2015 (p < 0.0001) within expansion states. Within non-expansion states, compared with 2013, there were significant utilization decreases of 18% in 2014 (p < 0.0001) and 11% in 2015 (p = 0.0002).

CONCLUSIONS

Medicaid expansion was associated with significant increases in Medicaid-funded THA and TKA utilization in 9 states. As additional states consider expanding Medicaid programs and as alternative health reforms that increase insurance eligibility are debated, surgeons, administrators, and policymakers should prepare for a surge in the utilization of THA and TKA.

A qualitative study of life satisfaction after surgery for adult traumatic brachial plexus injury

Aims

Brachial plexus injury (BPI) is an often devastating injury that affects patients physically and emotionally. The vast majority of the published literature is based on surgeon-graded assessment of motor outcomes, but the patient experience after BPI is not well understood. Our aim was to better understand overall life satisfaction after BPI, with the goal of identifying areas that can be addressed in future delivery of care.

Methods

We conducted semi-structured interviews with 15 BPI patients after initial nerve reconstruction. The interview guide was focused on the patient’s experience after BPI, beginning with the injury itself and extending beyond surgical reconstruction. Inductive and deductive thematic analysis was used according to standard qualitative methodology to better understand overall life satisfaction after BPI, contributors to life satisfaction, and opportunities for improvement.

Results

Among the 15 patients interviewed, the following themes emerged: 1) happiness and life satisfaction were noted despite limitations in physical function; 2) quality of social support influences life satisfaction during recovery from BPI; and 3) social participation and having a sense of purpose impact life satisfaction during recovery from BPI.

Conclusion

How patients perceive their BPI treatment and recovery varies widely, and is not directly linked to their self-reported functional outcome. Patients with stronger social circles and activities that give them a sense of fulfillment were more likely to be satisfied with their current status. Evaluating a patient’s social network, goals, and potential supportive adaptations early in the treatment timeline through coordinated multidisciplinary care may improve overall satisfaction during recovery from BPI.

Social Support and Coping Strategies in Patients with Traumatic Brachial Plexus Injury

BACKGROUND

Emotional and social characteristics may influence rehabilitation and recovery after traumatic brachial plexus injury.

PURPOSES

We sought to investigate if traumatic brachial plexus injury patients have different levels of social support and employ distinct coping strategies from uninjured control subjects. In addition, we studied which coping strategies are more commonly used among traumatic brachial plexus injury patients.

METHODS

Questionnaires for social support (Interpersonal Support Evaluation List and Social Support Questionnaire) and coping strategies (Brief-Coping Orientation to Problems Experienced) were administered to traumatic brachial plexus injury patients and an age- and sex-matched volunteer cohort (without brachial plexus injury).

RESULTS

There were no differences in interpersonal support (mean [SD] = 26.0 [8.6], 26.5 [6.8]), number of persons available for emotional support, and satisfaction with support between traumatic brachial plexus injury patients (n = 36) and volunteers (n = 43). The following coping strategies were more common among traumatic brachial plexus injury patients: active coping, self-distraction, denial, behavioral disengagement, venting, planning, self-blame, and acceptance.

CONCLUSION

Patients with traumatic brachial plexus injury have similar levels of social support as healthy volunteers but are more likely to use an array of coping strategies. Surgeons and other clinicians should be aware of coping strategies favored by patients, particularly the potential for behaviors detrimental to recovery such as behavioral disengagement, self-blame, and denial. This work will inform future investigations into the influence of social support and coping strategies on clinical outcomes after traumatic brachial plexus injury.

Variability in Surgeon Approaches to Emotional Recovery and Expectation Setting After Adult Traumatic Brachial Plexus Injury

Purpose

Increasing emphasis has been placed on multidisciplinary care for patients with traumatic brachial plexus injury (BPI), and there has been a growing appreciation for the impact of psychological and emotional components of recovery. Because surgeons are typically charged with leading the recovery phase of BPI, our objective was to build a greater understanding of surgeons’ perspectives on the care of BPI patients and potential areas for improvement in care delivery.

Methods

We conducted semistructured qualitative interviews with 14 surgeons with expertise in BPI reconstruction. The interview guide contained questions regarding the surgeons’ practice and care team structure, their attitudes and approaches to psychological and emotional aspects of recovery, and their preferences for setting patient expectations. We used inductive thematic analysis to identify themes.

Results

There was a high degree of variability in how surgeons addressed emotional and psychological aspects of recovery. Whereas some surgeons embraced the practice of addressing these components of care, others felt strongly that BPI surgeons should remain focused on technical aspects of care. Several participants described the emotional toll that caring for BPI patients can have on surgeons and how this concern has affected their approach to care. Surgeons also recognized the importance of setting preoperative expectations. There was an emphasis on setting low expectations in an attempt to minimize the risk for dissatisfaction. Surgeons described the challenges in effectively counseling patients about a condition that is prone to substantial injury heterogeneity and variability in functional outcomes.

Conclusions

Our results demonstrate wide variability in how surgeons address emotional, psychological, and social barriers to recovery for BPI patients.

Clinical relevance

Best practices for BPI care are difficult to establish because of the relative heterogeneity of neurologic injury, the unpredictable impact and recovery of the patient, and the substantial variability in physician approach to the care of these patients.

"Pill Pushers and CBD Oil"-A Thematic Analysis of Social Media Interactions About Pain After Traumatic Brachial Plexus Injury

Purpose

Brachial plexus injury (BPI) patients use on-line groups for peer support, often seeking information from Facebook groups devoted to BPI. We hypothesized that a qualitative thematic analysis of posts from BPI Facebook groups would demonstrate the areas in which patients were seeking information regarding treatment of BPI and reveal potential sources of misinformation that patients may encounter.

Methods

We identified the 2 most popular public Facebook groups for BPI by searching key words “traumatic brachial plexus injury.” We selected posts containing comments regarding BPI from November 1, 2018 through October 31, 2019. We excluded posts regarding brachial plexus birth injury. We used iterative inductive and deductive thematic analysis for the qualitative data to identify recurring topics, knowledge gaps, potential roles of patient educational interventions, and patient interaction dynamics. Two investigators independently coded all posts and resolved discrepancies by discussion.

Results

A total of 7,694 posts from 2 leading Facebook support groups were analyzed. Three themes emerged: (1) When discussing pain management, there was recurring anti-opioid sentiment. Posters who currently used opioids or supported those who did discussed perceived effects of the opioid epidemic on their treatment, on their relationships with care providers, and on availability of the medication. (2) Posters advocated for alternatives to traditional approaches to pain management, referring to prescribers as pill pushers and touting cannabinoids as a safer and more effective replacement. (3) There was strong anti-gabapentinoid sentiment owing to reported adverse effects and a perceived lack of efficacy, despite its role as a first-line treatment for neuropathic pain.

Conclusions

Examination of posts from Facebook support groups for BPI revealed recurring themes, questions, misinformation, and opinions from posters with regard to treatment of neuropathic pain. These findings can help clinicians who care for BPI patients identify areas to focus on during patient encounters to address neuropathic pain that commonly occurs with BPI.

Clinical relevance

Brachial plexus injury surgeons should be aware of information, misinformation, and opinions on social media, because these may influence patient–surgeon interactions.

Trends in Nerve Transfer Procedures Among Board-Eligible Orthopedic Hand Surgeons

Purpose

Enthusiasm for peripheral nerve transfers increased over the past several years, but further studies are still needed to establish the role of these procedures in peripheral nerve reconstruction. The primary goal of this study was to describe the frequency of nerve transfer surgery among newly trained orthopedic surgeons.

Methods

We queried the American Board of Orthopaedic Surgery Part II case log database for all nerve reconstruction Current Procedural Terminology codes for examination years 2004 to 2018 for surgeries performed between 2003 and 2017. Information collected for each patient included examination year, year of surgery, surgeon fellowship training subspecialty, geographic region (as defined by the American Board of Orthopaedic Surgery Part II case log database), patient age, and patient sex.

Results

A total of 3,359 nerve reconstruction cases were logged by 1,542 individual candidates from examination years 2004 to 2018. Of the nerve reconstruction codes, 2.1% were nerve transfer codes. There was a statistically significant increase in the proportion of nerve transfer codes over the study period, from 0% of nerve reconstruction codes in examination years 2004 to 2006 to 4.1% of nerve reconstruction codes in examination years 2016 to 2018 (Z = –6.82; P < .001).

Conclusions

There has been an increase in the number of nerve transfer procedures relative to all nerve reconstruction codes for peripheral nerve conditions.

Clinical relevance

There is a modest but significant increase in nerve transfer procedures over time among newly trained orthopedic surgeons, which suggests the need for long-term outcomes studies for nerve transfers procedures performed in the setting of peripheral nerve conditions.

Unmet Need for Total Joint Arthroplasty in Medicaid Beneficiaries After Affordable Care Act Expansion

BACKGROUND

The utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) increased after Medicaid expansion under the U.S. Affordable Care Act (ACA), suggesting a potential unmet need for THA and TKA. We examined the timing of THA and TKA in patients after obtaining Medicaid expansion insurance coverage. We hypothesized that patients with Medicaid expansion insurance would undergo a surgical procedure sooner than patients in traditional Medicaid populations.

METHODS

We used administrative data from a Medicaid managed care company to determine the timing of primary THA and TKA in patients who were 18 to 64 years of age in 4 states with Medicaid expansion (Illinois, Ohio, Oregon, and Washington) and 4 states without Medicaid expansion (Louisiana, Mississippi, Texas, and Wisconsin) from 2008 to 2015. The insurance types were Medicaid expansion, Medicaid plans for Supplemental Security Income (SSI), or Temporary Assistance for Needy Families (TANF). Roughly, these 3 groups correspond to relatively healthy childless adults, relatively unhealthy disabled adults, and parents of children with Medicaid insurance. The main outcome measure was time from enrollment to the surgical procedure. The primary exposure of interest was insurance type. We used a generalized linear regression model to adjust for patient age, sex, social deprivation, surgeon supply and reimbursement, and state-level Medicaid enrollment.

RESULTS

In the unadjusted analysis of 4,117 patients, there was a significantly shorter time from enrollment to THA and TKA for the expansion group (median, 7.5 months) relative to the SSI group (median, 16.1 months; p < 0.0001) and the TANF group (median, 12.2 months; p < 0.0001). In the adjusted analysis, the time from enrollment to THA and TKA was significantly shorter in the expansion group (β, -1.21 [95% confidence interval (CI), -1.35 to -1.07]; p < 0.001) compared with the TANF group (β, -0.27 [95% CI, -0.38 to -0.17]; p < 0.001) and the SSI group (reference). Compared with the SSI group, these coefficients are equivalent to a 70% shorter time to the surgical procedure in the expansion group and a 24% shorter time to the surgical procedure in the TANF group.

CONCLUSIONS

Our findings suggest an unmet need for THA and TKA among newly enrolled Medicaid expansion beneficiaries. This need should be considered by surgeons, hospitals, and policymakers in ensuring access to care. Furthermore, consideration should be given to existing insurance-based disparities in access to orthopaedic care, as these may be exacerbated by an increased demand for THA and TKA from Medicaid expansion beneficiaries.

When (Almost) Everyone is Above Average: A Critical Analysis of American Orthopaedic Association Committee of Residency Directors Standardized Letters of Recommendation

The American Orthopaedic Association introduced standardized letters of recommendations (SLORs) to improve on traditional letters of recommendations by “providing a global prospective on an applicant.” However, no study has defined the utilization of SLORs, the distribution of applicant ratings in SLORs, or the impact of sex, race, or degree of involvement between the letter writer and applicant on SLOR domain ratings.
