Outcomes of Thumb Metacarpophalangeal Joint Arthrodesis Using the XMCP Intramedullary Interlocking Device.

Purpose: The intramedullary interlocking device for metacarpophalangeal (MCP) joint arthrodesis (XMCP, Extremity Medical, Parsippany, NJ) has been shown to promote union at a precise angle, provide strong fixation without the need for prolonged immobilization, and lower the incidence of hardware irritation and revision surgery. In this study, we evaluated the clinical outcomes of patients undergoing MCP joint arthrodesis with the XMCP system using a retrospective chart review, patient reported outcomes, and radiographic analysis. Methods: A retrospective chart review and phone survey was conducted on 57 patients (58 cases) from a single institution between 2017 and 2022. The primary outcome was patient satisfaction, including pre- and postoperative Numeric Rating Scale (NRS) pain scores, Disabilities of Arm Shoulder and Hand (QuickDASH) outcomes, perceived grip strength, and willingness to undergo the procedure again. Secondary outcomes included the need for revision procedures, successful fusion of arthrodesis, and postoperative complications. Results: Of the 57 patients who underwent MCP joint arthrodesis of the thumb using the XMCP fusion device, a total of 43 (75%) completed the phone survey. The average age of patients was 67 years with an average clinical follow-up of 9 months (range 1-65 months). Patients who participated in the phone survey questionnaire had an average QuickDASH score of 24.7 ± 20.5. Average perceived NRS scores were 6.2 ± 3.5 and 1.2 ± 2.1 before and after surgery, respectively. Average perceived grip strength of patients was 3 ± 1.3 out of 5. When evaluating for concurrent procedures, there was no statistically significant difference in pre- or postoperative NRS scores. In total, 38 (88%) patients were satisfied with the procedure, and 39 (91%) patients would undergo the procedure again. Conclusion: Metacarpophalangeal joint arthrodesis of the thumb with the intramedullary fusion device is reproducible, allows for immediate use without immobilization, has a low number of complications, and provides improved function and pain relief. Level of Evidence: Therapeutic III.

Cubital Tunnel Syndrome: Does a Consensus Exist for Diagnosis?

PURPOSE: Cubital tunnel syndrome (CuTS) is the second most common compressive neuropathy of the upper extremity. We aimed to determine a consensus among experts using the Delphi method for clinical criteria that could be validated further for the diagnosis of CuTS. METHODS: The Delphi method was used for establishing a consensus among a group of expert panelists, comprising 12 hand and upper-extremity surgeons, who ranked the diagnostic clinical importance of 55 items related to CuTS on a scale from 1 (least important) to 10 (most important). The average and SDs of each item were calculated, and Cronbach α was used to assess homogeneity among the panelist-ranked items. RESULTS: All panelists answered the 55-item questionnaire. A Cronbach α value of 0.963 was obtained on the first iteration. The top criteria that were considered most clinically relevant to the diagnosis of CuTS among the group were determined based on the most highly ranked and correlated items among the expert panelist group. The criteria based on which there was agreement were as follows: (1) paresthesias in ulnar nerve distribution, (2) symptoms precipitated by increased elbow flexion/positive elbow flexion tests, (3) positive Tinel sign at the medial elbow, (4) atrophy/weakness/ late findings (eg, claw hand of the ring/small finger and Wartenberg or Froment sign) of ulnar nerve-innervated muscles of the hand, (5) loss of two-point discrimination in ulnar nerve distribution, and (6) similar symptoms on the involved side after successful treatment on the contralateral side. CONCLUSIONS: Our study demonstrated a consensus among an expert panelist group of hand and upper-extremity surgeons on potential diagnostic criteria for CuTS. This consensus on diagnostic criteria may help clinicians readily diagnose CuTS in a standardized form; however, further weighting and validation are necessary prior to the development of a formal diagnostic scale. CLINICAL RELEVANCE: This study is the first step in producing a consensus on how to diagnose CuTS.

Social determinants of health and disease in companion dogs: a cohort study from the Dog Aging Project.

Exposure to social environmental adversity is associated with health and survival across many social species, including humans. However, little is known about how these health and mortality effects vary across the lifespan and may be differentially impacted by various components of the environment. Here, we leveraged a relatively new and powerful model for human aging, the companion dog, to investigate which components of the social environment are associated with dog health and how these associations vary across the lifespan. We drew on comprehensive survey data collected on 21,410 dogs from the Dog Aging Project and identified five factors that together explained 33.7% of the variation in a dog's social environment. Factors capturing financial and household adversity were associated with poorer health and lower physical mobility in companion dogs, while factors that captured social support, such as living with other dogs, were associated with better health when controlling for dog age and weight. Notably, the effects of each environmental component were not equal: the effect of social support was 5× stronger than financial factors. The strength of these associations depended on the age of the dog, including a stronger relationship between the owner's age and the dog's health in younger as compared to older dogs. Taken together, these findings suggest the importance of income, stability and owner's age on owner-reported health outcomes in companion dogs and point to potential behavioral and/or environmental modifiers that can be used to promote healthy aging across species.

Associations between Neighborhood Disadvantage and Dog Walking among Participants in the Dog Aging Project.

Although neighborhood socioeconomic disadvantage is negatively related to overall physical activity, prior studies reveal a complex relationship between disadvantage and particular walking behaviors. While disadvantage is associated with reduced recreational walking through a hypothesized "fear-of-crime" mechanism, the built environment in disadvantaged neighborhoods may encourage utilitarian walking. To date, no study has assessed how disadvantage relates to dog walking, a distinct walking behavior that is neither strictly recreational nor utilitarian but represents a key mechanism through which pet ownership may affect human health. We employ a large (n = 19,732) dataset from the Dog Aging Project to understand how neighborhood disadvantage is associated with dog walking when controlling for individual-, household-, and environmental-level factors. We find that dog owners in more disadvantaged neighborhoods report less on-leash walking activity compared to owners in advantaged neighborhoods and discuss the possibility of a fear-of-crime mechanism underlying this association. These findings improve our understanding of the relationship between neighborhood disadvantage and physical function and highlight the need for public health interventions that encourage dog ownership to consider neighborhood disadvantage.

Age and Physical Activity Levels in Companion Dogs: Results From the Dog Aging Project.

While there has been an abundance of studies on the important relationship between physical activity and age in both dogs and humans, studies on dogs have primarily focused on how a dog's biological characteristics, such as their weight, affect the age-activity relationship. To date, there is little knowledge about how this relationship may be associated with contextual- and owner-level characteristics. We leveraged a large and novel data set from the Dog Aging Project (DAP) to investigate the extent to which the age-activity relationship is associated with certain dog and owner characteristics, namely dog size, owner age, and the environment in which they live. Dogs are a unique model for aging research as they are exposed to similar social and environmental elements as humans but have a shorter life span, allowing researchers to observe their entire life course. We find that older dogs are less active than younger dogs; rural dogs are more active than suburban and urban dogs, especially at younger ages; and larger dogs are more active than smaller dogs. These findings are generally consistent with previous studies. However, a surprising finding is that older owners have more active dogs than younger owners. As one of the first studies to utilize the large survey data from the DAP, this study lays the foundation for future investigations to further understand and identify the biological, social, and environmental causes, as well as consequences, of aging.

Trust in Hospital Physicians Among Patients With Substance Use Disorder Referred to an Addiction Consult Service: A Mixed-methods Study.

BACKGROUND: Trust is essential in patient-physician relationships. Hospitalized patients with substance use disorders (SUDs) often experience stigma and trauma in the hospital, which can impede trust. Little research has explored the role of hospital-based addictions care in creating trusting relationships with patients with SUDs. This study describes how trust in physicians changed among hospitalized people with SUDs who were seen by an interprofessional addiction medicine service. METHODS: We analyzed data from hospitalized patients with SUD seen by an addiction consult service from 2015 to 2018. Participants completed surveys at baseline and 30 to 90 days after hospital discharge. Follow-up assessments included open-ended questions exploring participant experiences with hospitalization and the addiction consult service. We measured provider trust using the Wake Forest Trust scale. We modeled trust trajectories using discrete mixture modeling, and sampled qualitative interviews from those trust trajectories. RESULTS: Of 328 participants with SUD who had prior hospitalizations but had not previously been seen by an addiction consult service, 196 (59.8%) had both baseline and follow-up trust scores. We identified 3 groups of patients: Persistent-Low Trust, Increasing Trust, and Persistent-High Trust and 4 qualitative themes around in-hospital trust: humanizing care, demonstrating addiction expertise, reliability, and granting agency. CONCLUSIONS: Most participants retained or increased to high trust levels after hospitalization with an addiction consult service. Addiction consult services can create environments where healthcare providers build trust with, and humanize care for, hospitalized patients with SUD, and can also mitigate power struggles that hospitalized patients with SUD frequently experience.

Successful Surgical Repair of Acute Quadriceps Tendon Rupture Utilizing Cortical Button Fixation: A Case Report.

BACKGROUND Timely diagnosis and surgical treatment are often needed to restore function of the extensor mechanism after rupture of the quadriceps tendon. Several techniques for quadriceps tendon repair have been reported, including suture anchors and bone tunnels. Cortical button fixation, or the use of an adjustable cortical fixation device, is a local and biomechanically strong internal brace technique used to treat ligament and tendon injuries. This report is of a 69-year-old man who experienced a quadriceps tendon rupture while golfing and underwent a successful surgical repair using cortical button fixation. CASE REPORT A 69-year-old man sustained an injury after slipping while golfing. He had immediate left knee pain and inability to bear weight. Radiographs demonstrated patella baja with an acute superior pole avulsion fracture of the patella, consistent with rupture of the quadriceps tendon. Surgical repair was discussed. Technique: After soft tissue debridement, the quadriceps tendon was debrided from the frayed and edematous edges. Two Krackow-type stitches were placed with #2 Fibertape and passed through 2 cortical buttons. Two bone tunnels were drilled from the superior to the inferior poles of the patella, bicortically. The cortical button was passed and appropriately tensioned. CONCLUSIONS Although acute quadriceps tendon rupture is commonly treated with transosseous suture repair and suture anchor repair, this report demonstrates that cortical button fixation was a successful procedure with strong biomechanical properties, resulting in the early return of function and range of motion.

The Use a Prophylactic Intramedullary Tibial Nail for a Stress Fracture in a High-Level Athlete.

INTRODUCTION: Mid-diaphyseal anterior tibial stress fractures can be debilitating injuries. They have been described occurring in athletes due to repetitive lower extremity trauma. The purpose of our study was to highlight a case of an athlete sustaining a tibial stress fracture with multiple cortical defects. CASE REPORT: We present an 18-year-old collegiate bound athlete who sustained a tibial stress fracture with multiple cortical defects. The clinical decision, after failure of conservative treatment, was made to treat the patient with tibial intramedullary nailing. She was able to return to full unrestricted activities, including high-level sports participation. Our case report specifically describes a case of a high-level athlete with multiple anterior tibial linear cortical defects from a chronic stress fracture. CONCLUSION: When conservative management for mid-diaphyseal anterior stress fractures fails, the utilization of prophylactic tibial nailing is a viable option. The decision for surgical intervention is dependent on many factors including patient's activity level and characteristics, failure of conservative management, and radiographic evidence of non-healing stress fractures.

Recommendations for integrating peer mentors in hospital-based addiction care.

Legislators and health systems have recently begun to explore the use of peer mentors as part of hospital-based addiction teams. Integrating peers into hospitals is a complex undertaking still in its infancy. Peers' lived experience of addiction and its consequences, combined with their distance from medical culture and hierarchy, is at the core of their power - and creates inherent challenges in integrating peers into hospital settings. Successful integration of peers in hospitals has unique challenges for individual providers, health systems, and the peers themselves. We have included peers as part of a hospital-based addiction medicine team at our hospital since 2015. In this article, we outline some unique challenges, share lessons learned, and provide recommendations for integrating peers into hospital-based SUD care. Challenges include the rigid professional hierarchy of hospitals which contrasts with peers' role, which is built on shared life experience and relationship; different expectations regarding professional boundaries and sharing personal information; the intensity of the hospital environment; and, illness severity of hospitalized people which can be emotionally draining and increase peers' own risk for relapse. Recommendations focus on establishing a way to finance the peer program, clearly defining the peer role, creating a home base within hospital settings, creating a collaborative and structured process for hiring and retaining peers, identifying peers who are likely to succeed, providing initial and ongoing training to peers that extends beyond typical peer certification, ways to introduce peer program to hospital staff, and providing regular, meaningful supervision. We hope that our recommendations help other hospital systems capitalize on the practical lessons learned from our experience.

Predictors of Opioid and Alcohol Pharmacotherapy Initiation at Hospital Discharge Among Patients Seen by an Inpatient Addiction Consult Service.

BACKGROUND: Medications for opioid use disorder (MOUD) and alcohol use disorder (MAUD) are effective and under-prescribed. Hospital-based addiction consult services can engage out-of-treatment adults in addictions care. Understanding which patients are most likely to initiate MOUD and MAUD can inform interventions and deepen understanding of hospitals' role in addressing substance use disorders (SUD). OBJECTIVE: Determine patient- and consult-service level characteristics associated with MOUD/MAUD initiation during hospitalization. METHODS: We analyzed data from a study of the Improving Addiction Care Team (IMPACT), an interprofessional hospital-based addiction consult service at an academic medical center. Researchers collected patient surveys and clinical data from September 2015 to May 2018. We used logistic regression to identify characteristics associated with medication initiation among participants with OUD, AUD, or both. Candidate variables included patient demographics, social determinants, and treatment-related factors. RESULTS: Three hundred thirty-nine participants had moderate to severe OUD, AUD, or both and were not engaged in MOUD/MAUD care at admission. Past methadone maintenance treatment (aOR 2.07, 95%CI (1.17, 3.66)), homelessness (aOR 2.63, 95%CI (1.52, 4.53)), and partner substance use (aOR 2.05, 95%CI (1.12, 3.76) were associated with MOUD/MAUD initiation. Concurrent methamphetamine use disorder (aOR 0.32, 95%CI (0.18, 0.56)) was negatively associated with MOUD/MAUD initiation. CONCLUSIONS: The association of MOUD/MAUD initiation with homelessness and partner substance use suggests that hospitalization may be an opportunity to reach highly-vulnerable people, further underscoring the need to provide hospital-based addictions care as a health-system strategy. Methamphetamine's negative association with MOUD/MAUD warrants further study.

"If It Wasn't for Him, I Wouldn't Have Talked to Them": Qualitative Study of Addiction Peer Mentorship in the Hospital.

BACKGROUND: Hospitalizations related to substance use disorders (SUD) are skyrocketing. Hospital providers commonly feel unprepared to care for patients with SUD and patients with SUD commonly feel discriminated against by hospital staff. This tension can lead to provider burnout and poor patient outcomes. Research in ambulatory settings suggests that peer mentors (PMs) can improve substance use outcomes and patient experience. However, no study has examined the role of peer mentorship for patients with SUD in hospitals. OBJECTIVE: Understand how peer mentorship affects care for hospitalized patients with SUD, and how working in a hospital affects PMs' sense of professional identity. DESIGN: Qualitative study utilizing participant observation, individual interviews, and focus groups related to the PM component of the Improving Addiction Care Team (IMPACT), a hospital-based interprofessional addiction medicine consult service. PARTICIPANTS: IMPACT providers, patients seen by IMPACT, PMs, and a PM supervisor. APPROACH: Qualitative thematic analysis. KEY RESULTS: PMs occupy a unique space in the hospital and are able to form meaningful relationships with hospitalized patients based on trust and shared lived experiences. PMs facilitate patient care by contextualizing patient experiences to teams and providers. Reciprocally, PMs "translate" provider recommendations to patients in ways that patients can hear. Respondents described PMs as "cultural brokers" who have the potential to transfer trust that they have earned with patients to providers and systems who may otherwise be viewed as untrustworthy. While PMs felt their role led to professional and personal development, the intensity of the role in the hospital setting also put them at risk for emotional drain and stress. CONCLUSIONS: While integrating PMs into hospital care presents substantial challenges, PMs may act as a "secret weapon" to engage often marginalized hospitalized patients with SUD and improve patient and provider experience.

"We've Learned It's a Medical Illness, Not a Moral Choice": Qualitative Study of the Effects of a Multicomponent Addiction Intervention on Hospital Providers' Attitudes and Experiences.

BACKGROUND: Substance use disorders (SUD) represent a national epidemic with increasing rates of SUD-related hospitalizations. However, most hospitals lack expertise or systems to directly address SUD. Healthcare professionals feel underprepared and commonly hold negative views toward patients with SUD. Little is known about how hospital interventions may affect providers' attitudes and experiences toward patients with SUD. OBJECTIVE: To explore interprofessional hospital providers' perspectives on how integrating SUD treatment and care systems affect providers' attitudes, beliefs, and experiences. DESIGN: In-depth semi-structured interviews and focus groups. The study was part of a formative evaluation of the Improving Addiction Care Team (IMPACT), an interprofessional hospital-based addiction medicine service with rapid-access pathways to post-hospital SUD treatment. SETTING: Single urban academic hospital in Portland, Oregon. PARTICIPANTS: Multidisciplinary hospital providers. MEASUREMENTS: We conducted a thematic analysis using an inductive approach at a semantic level. RESULTS: Before IMPACT, participants felt that hospitalization did not address addiction, leading to untreated withdrawal, patients leaving against medical advice, chaotic care, and staff "moral distress." Participants felt that IMPACT "completely reframes" addiction as a treatable chronic disease, improving patient engagement and communication, and humanizing care. Participants valued post-hospital SUD treatment pathways and felt having systems to address SUD reduced burnout and provided relief. Providers noted that IMPACT had limited ability to address poverty or engage highly ambivalent patients. CONCLUSIONS: Providers' distress of caring for patients with SUD is not inevitable. Hospital-based SUD interventions can reframe providers' views of addiction and may have significant implications for clinical care and providers' well-being.

Lessons learned from the implementation of a medically enhanced residential treatment (MERT) model integrating intravenous antibiotics and residential addiction treatment.

BACKGROUND: Hospitalizations for severe infections associated with substance use disorder (SUD) are increasing. People with SUD often remain hospitalized for many weeks instead of completing intravenous antibiotics at home; often, they are denied skilled nursing facility admission. Residential SUD treatment facilities are not equipped to administer intravenous antibiotics. We developed a medically enhanced residential treatment (MERT) model integrating residential SUD treatment and long-term IV antibiotics as part of a broader hospital-based addiction medicine service. MERT had low recruitment and retention, and ended after six months. The goal of this study was to describe the feasibility and acceptability of MERT, to understand implementation factors, and explore lessons learned. METHODS: We conducted a mixed-methods evaluation. We included all potentially eligible MERT patients, defined by those needing ≥2 weeks of intravenous antibiotics discharged from February 1 to August 1, 2016. We used chart review to identify diagnoses, antibiotic treatment location, and number of recommended and actual IV antibiotic-days completed. We audio-recorded and transcribed key informant interviews with patients and staff. We conducted an ethnographic analysis of interview transcripts and implementation field notes. RESULTS: Of the 45 patients needing long-term intravenous antibiotics, 18 were ineligible and 20 declined MERT. 7 enrolled in MERT and three completed their recommended intravenous antibiotic course. MERT recruitment barriers included patient ambivalence towards residential treatment, wanting to prioritize physical health needs, and fears of untreated pain in residential. MERT retention barriers included high demands of residential treatment, restrictive practices due to PICC lines, and perceptions by staff and other residents that MERT patients "stood out" as "different." Despite the challenges, key informants felt MERT was a positive construct. CONCLUSIONS: Though MERT had many possible advantages; it proved more challenging to implement than anticipated. Our lessons may be applicable to future models integrating post-hospital intravenous antibiotics and SUD care.

Fulminant Septicemia from Aeromonas hydrophilia in a Nonmobile Diabetic Patient.

We report an unusual case of Aeromonas hydrophilia septicemia in a nonmobile diabetic patient secondary to contaminated well water used for bathing with a portal of entry through chronic forefoot and heel ulcers. To date, there are no documented cases similar to this patient's presentation. Aeromonas hydrophilia is commonly distributed among aquatic environments and tends to be found during warmer months. It is a rare cause of disease but can be life threatening and deadly, as in our case, in immunocompromised individuals. As podiatric physicians, we must remain diligent and have a high index of suspicion to identify patients at risk for this rare but serious infection and administer treatment aggressively to limit morbidity and mortality.

A systematic literature review of synovial chondromatosis and pigmented villonodular synovitis of the hip.

OBJECTIVES: Benign synovial diseases of the hip including Synovial Chondromatosis (SC) and Pigmented Villonodular Synovitis (PVNS) are devastating diseases. Initially, patients present with hip pain unrelieved by conservative measures. The diagnosis of PVNS and SC are often delayed, leading to progression of joint damage. The purpose of this review is to present the latest on the diagnosis, management, and prognosis of SC and PVNS of the hip. METHODS: An extensive systematic search of MEDLINE and PUBMED Databases was performed. Data parameters were set from 2005 to present day with set inclusion criteria. Systematic reviews were excluded. RESULTS: 427 abstracts were identified, with 12 articles meeting all inclusion criteria. Eight studies focused on SC, and 5 on PVNS. 233 patients with SC of the hip and 98 patients with PVNS of the hip were identified, a total of 331 patients. DISCUSSION: Benign Synovial disorders of the hip are rare. In patients with chronic hip pain secondary to benign synovial disorders, early diagnosis and surgical intervention demonstrate good outcomes, and patients may benefit due to prevention of morbidity from further joint destruction. There is no clear consensus between higher successes through open versus arthroscopic surgical debridement. In the final phase of benign synovial disorders of the hip, THA of different types based on the patient's age should be considered.
