RESUMEN

People with spinal cord injury (SCI) prioritize hand function above all else as a reconstructive goal, yet remain a markedly undertreated population by hand surgeons. This review article provides an overview of the epidemiology of SCI and the unmet clinical need of these patients. Further, this article outlines the natural history of SCI, including the expected spontaneous recovery over time and the expectations of hand function when treated with hand therapy alone. This review aims to equip reconstructive hand surgeons with a sound understanding of the basic principles of SCI and recovery and provide a rationale for when to intervene with surgery. In the last decade, this field has changed dramatically with the advent of reliable nerve transfers, making referral and surgical intervention time-sensitive. Therefore this review aims to highlight the expectations from hand therapy alone in this group, the urgent need for early referral to allow nerve transfer options to be viable, and the strategies for overcoming the barriers to these referrals. This offers the opportunity for surgeons to expand their tetraplegia practices while maximizing the considerable contributions to the hand function and quality of life of these patients.

RESUMEN

PURPOSE: The dermatomal distributions of the ulnar and median nerves on the palmar skin of the hand have been studied thoroughly. However, the anatomic course of the median and ulnar cutaneous nerve branches and how they supply the skin of the palm is not well understood. METHODS: The cutaneous branches of the median and ulnar nerves were dissected bilaterally in 9 fresh cadavers injected arterially with green latex. RESULTS: We observed 3 groups of cutaneous nerve branches in the palm of the hand: a proximal row group consisting of long branches that originated proximal to the superficial palmar arch and reached the distal palm, first web space, or hypothenar region; a distal row group consisting of branches originating between the superficial palmar arch and the transverse fibers of the palmar aponeurosis (these nerves had a longitudinal trajectory and were shorter than the branches originating proximal to the palmar arch); and a metacarpophalangeal group, composed of short perpendicular branches originating on the palmar surface of the proper palmar digital nerves at the web space. The radial and ulnar borders of the hand distal to the palmar arch were innervated by short transverse branches arising from the proper digital nerves of the index and little finger. Nerve branches did not perforate the palmar aponeurosis in 16 of 18 cases. CONCLUSIONS: The palm of the hand was consistently innervated by 20-35 mm long cutaneous branches originating proximal to the palmar arch and shorter branches originating distal to the palmar arch. These distal branches were either perpendicular or parallel to the proper palmar digital nerves. CLINICAL RELEVANCE: Transfer of long proximal row branches may present an opportunity to restore sensibility in nerve injuries.

RESUMEN

PURPOSE: Dissection of the radial nerve in the axilla and upper portion of and posterior aspect of arm may be necessary for brachial plexus reconstruction, in axillary nerve paralysis, and in radial nerve injuries. The radial nerve is in intimate contact with the profunda brachial artery (PBA). The authors sought to describe the relationship of the PBA with the radial nerve. MATERIALS AND METHODS: We dissected the PBA and the radial nerve bilaterally in 20 upper limbs from 10 fresh cadavers after subclavian artery injection with green latex. We studied the relationship of the PBA with the radial nerve, its branching patterns, and its diameters. In addition, we performed surgery on 5 patients with brachial plexus, radial, or axillary nerve injury in whom we dissected the PBA. RESULTS: The PBA was present in all dissections, originating from the brachial artery (n = 19 specimens) close to the latissimus dorsi tendon or from the subscapular artery (n = 1 specimen). In 15 dissections, the PBA bifurcated into an anterior (AB) and a posterior (PB) branch. In one dissection, the AB was absent. The AB traveled toward the triceps medial head. The PB flanked the radial nerve posteriorly and traveled around the humerus, with the radial nerve passing between the medial and the lateral head of the triceps. The AB and PB were longer than the PBA and measured on average 53 mm (SD ± 33 mm) and 39 mm (SD ± 26 mm), respectively. Intraoperatively, the radial nerve could be exposed in the upper arm by pulling the triceps medial head anteriorly together with the AB. The PB was lateral to the radial nerve in the posterior arm approach. CONCLUSIONS: In the upper arm, the radial nerve was not flanked by a single branch as postulated in anatomical textbooks but by 2 branches resulting from the bifurcation of the PBA. CLINICAL RELEVANCE: Awareness of PBA anatomy is essential during radial nerve dissection from the anterior or posterior arm approach.

RESUMEN

The T1 nerve root is not routinely thought of as innervating the extensors of the thumb and fingers. Work by Bertelli and Ghizoni proposed that the pattern of brachial plexus paralysis with intact hand function and thumb and finger extensors traditionally attributed to C5/6/7 root injury is in fact a C5/6/7/8 injury, with only T1 remaining intact - a 'T1 hand'. This case presents a 19-year-old male who was stabbed in the neck; exploratory surgery determined complete transection of the brachial plexus, with only the T1 nerve root remaining intact. Clinical examination demonstrated grade M4 pronation (with pronator quadratus), wrist extension (with extensor carpi ulnaris), thumb and finger extension (with extensor policis longus and brevis, extensor digitorum communis and extensor index proprius), wrist flexion (with palmaris longus), finger flexion (with flexor digitorum superficialis and profundus), thumb flexion (with flexor policis longus), and thenar and hypothenar muscles. Extensor carpi radialis longus and brevis, flexor carpi radialis and flexor carpi ulnaris were paralyzed. Triceps scored M2. This case provides unequivocal evidence that the T1 root provides significant innervation to the extrinsic thumb and finger extensors.

RESUMEN

BACKGROUND: Post-mastectomy free-flap breast reconstruction is becoming increasingly common in the United States. However, predicting which patients may suffer complications remains challenging. We sought to apply the validated modified frailty index (mFI) to free-flap breast reconstruction in breast cancer patients and determine its utility in predicting negative outcomes. METHODS: We conducted a retrospective study using National Surgical Quality Improvement Project (NSQIP). All patients who had a CPT code of 19364, indicative of free tissue transfer for breast cancer reconstruction, were included. Data on preoperative characteristics and postoperative outcomes were collected. Patients were separated based on the number of mFI factors present into three categories: 0, 1, and > 2 factors. Preoperative demographics, clinical status, and other comorbidities were also studied. Negative outcomes were compared using multivariate logistic regression. RESULTS: 11,852 patients (mean age 50.9 ± 9.5) were found; 24.2% had complications, comparable to previous literature. mFI is predictive of all types of negative outcomes. 22.5% of all patients with 0 mFI, 27.7% of patients with 1 mFI and 34.2% of patients with at least two mFI had a negative outcome. The most common factors contributing to the mFI were history of hypertension (24.8%) and diabetes (6.1%). mFI was found to be an isolated risk factor for negative outcomes, along with steroid use, American Society of Anesthesiology (ASA) classification, body mass index, and immediate, and bilateral operations. CONCLUSIONS: This NSQIP-based study for patients undergoing free flap breast reconstruction shows that the mFI holds predictive value regarding negative outcomes. This provides more information to properly counsel patients before free flap breast reconstruction surgery.

RESUMEN

OBJECTIVE: To measure surgeon engagement and preferred video duration in a video-based learning program for nerve surgery. BACKGROUND: Educational videos can improve, standardize, and democratize best practices in surgery. To improve care internationally, educators must optimize their videos for learning. However, surgeon engagement and optimal video duration remain undefined. METHODS: A YouTube channel and a video-based learning website, PASSIO Education (passioeducation.com), were examined from 2011 to 2017. We assessed views, geographic location, audience engagement (average percent of video watched), audience retention (percent of viewers at each timepoint), and usage of short (median 7.4, range 4.1-20.3 min) and long (median 17.2, range 6.1-47.7 min) video formats for the same procedures. A survey of PASSIO Education membership examined preferred video duration. RESULTS: Our 117 nerve surgery videos attained over 3 million views with 69% originating outside of the United States. While YouTube achieved more international exposure, PASSIO Education attained a greater mean engagement of 48.4% (14.3% absolute increase, P < 0.0001). Surveyed surgeons (n = 304) preferred longer videos when preparing for infrequent or difficult cases compared with routine cases (P < 0.0001). Engagement declined with video duration, but audience retention between short and long video formats was correlated (τB = 0.52, P < 0.0001). CONCLUSIONS: For effective spread of best practices, we propose the joint use of YouTube for audience outreach and a surgeon-focused platform to maximize educational value. Optimal video duration is surgeon- and case-dependent and can be addressed through offering multiple video durations and interactive viewing options.

RESUMEN

PURPOSE: Nerve transfer surgery is used to restore upper extremity function following cervical spinal cord injury (SCI) with substantial variation in outcomes. The injury pattern in SCI is complex and can include isolated upper motor neuron (UMN) and combined UMN/lower motor neuron (LMN) dysfunction. The purpose of the study was to determine the most effective diagnostic technique for determining suitable candidates for nerve transfer surgery in SCI. METHODS: Medical records were reviewed of patients who had nerve transfers to restore upper extremity function in SCI. Data collected included (1) preoperative clinical examination and electrodiagnostic testing; (2) intraoperative neuromuscular stimulation (NMS); and (3) nerve histopathology. Preoperative, intraoperative, and postoperative data were compared to identify predictors of isolated UMN versus combined UMN/LMN injury patterns. RESULTS: The study sample included 22 patients with 50 nerve transfer surgeries and included patients ranging from less than 1 year to over a decade post-SCI. Normal recipient nerve conduction studies (NCS) before surgery corresponded to the intraoperative presence of recipient NMS and postoperative histopathology that showed normal nerve architecture. Conversely, abnormal recipient NCS before surgery corresponded with the absence of recipient NMS during surgery and patterns of denervation on postoperative histopathology. Normal donor preoperative manual muscle testing corresponded with the presence of donor NMS during surgery and normal nerve architecture on postoperative histopathology. An EMG of corresponding musculature did not correspond with intraoperative donor or recipient NMS or histopathological findings. CONCLUSIONS: NCS better predict patterns of injury in SCI than EMG. This is important information for clinicians evaluating people for late nerve transfer surgery even years post-SCI. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

RESUMEN

BACKGROUND: Peer-assisted learning (PAL) increasingly features within medical school curricula. While there is evidence of its effectiveness, less is known about how it promotes learning. Cognitive and social congruence between peer-tutor and student have been described as important concepts underpinning teaching and learning in PAL. We employed interpretative phenomenological analysis for an in-depth exploration of how medical students experience PAL sessions. METHODS: We conducted the study at The University of Manchester within a near-peer scheme aimed at developing clinical skills within clinical clerkship students. We conducted individual interviews with three peer tutors and five students. We undertook interpretive phenomenological analysis of interview transcripts. We subsequently synthesised an account of the study participants' lived experiences of PAL sessions from individual personal accounts to explore how medical students experience peer-assisted learning. This analysis was then used to complement and critique a priori educational theory regarding the mechanisms underlying PAL. RESULTS: Students experienced PAL sessions as a safe and egalitarian environment, which shaped the type and style of learning that took place. This was facilitated by close relationships with peer-tutors, with whom they shared a strong sense of camaraderie and shared purpose. Peer-tutors felt able to understand their students' wider sociocultural context, which was the most important factor underpinning both the PAL environment and tutor-student relationship. Participants contrasted this relative safety, camaraderie and shared purpose of PAL with teaching led by more senior tutors in clinical settings. CONCLUSIONS: This study provides a rich description of the important factors that characterise medical students' experiences of PAL sessions. Participants felt a strong sense of support in PAL sessions that took into account their wider sociocultural context. Multiple factors interplayed to create a learning environment and tutor-student relationship that existed in contrast to teaching led by more senior, clinical tutors. The insight generated via IPA complemented existing theory and raised new lines of enquiry to better understand how the peer relationship fosters learning in PAL at medical school. We make recommendations to use insights from PAL for faculty and curriculum development.

RESUMEN

CONTEXT: The UK set a target of 20% of the surgical consultant workforce to be represented by women by 2009; in 2012, it remains 7%. Studies have attributed this shortfall to the nature of careers in surgery and differing career aspirations among women. OBJECTIVES: Rather than exploring barriers to participation, this study aims to explore the self-narratives of those women who do undertake surgical careers and who do come to see themselves as surgeons. METHODS: The study comprises 15 individual interviews with women in surgical careers, from those aspiring to be surgeons, to senior and retired surgeons. Data were explored using discourse analysis with a priori themes derived from the literature on women in surgery and Holland et al.'s theoretical framework of Figured Worlds. RESULTS: Discourses of being a surgeon and discourses of being a woman, existed in competition. Female surgeons figured surgery as a career requiring 100% dedication, as they did motherhood, although the demands of the two roles differed and consequently the roles were not discursively compatible. Many related powerfully negative experiences in which their gender had marked them out as 'other' within surgery. Women described how they were expected to show masculine traits as surgeons and the ways to consequently become legitimate in the surgical world as a 'woman surgeon'. They found creative ways to articulate how women in general, and feminine qualities in particular, enhanced surgery. Finally, some women engaged in identity work, termed 'world making', - the creative orchestration of discourses of surgeonhood and motherhood to be mutually sustaining. CONCLUSIONS: There is little discursive space in which to be both a successful woman and a successful surgeon. Those who combine these roles must either be innovative in refiguring what it means to be a woman or what it means to be a surgeon, or they must author a new space for themselves, a powerful discursive process termed 'world making'.

RESUMEN

OBJECTIVES: The hidden curriculum may be framed as the culture, beliefs and behaviours of a community that are passed to students outside formal course offerings. Medical careers involve diverse specialties, each with a different culture, yet how medical students negotiate these cultures has not been fully explored. Using surgery as a case study, we aimed to establish, first, whether a specialty-specific hidden curriculum existed for students, and second, how students encountered and negotiated surgical career options. METHODS: Using a constructivist grounded theory approach, we explored students' thoughts, beliefs and experiences regarding career decisions and surgery. An exploratory questionnaire informed the discussion schedule for semi-structured individual interviews. Medical students were purposively sampled by year group, gender and career intentions in surgery. Data collection and analysis were iterative: analysis followed each interview and guided the adaptation of our discussion schedule to further our evolving model. RESULTS: Students held a clear sense of a hidden curriculum in surgery. To successfully negotiate a surgical career, students perceived that they must first build networks because careers information flows through relationships. They subsequently enacted what they learned by accruing the accolades ('ticking the boxes') and appropriating the dispositions ('walking the talk') of 'future surgeons'. This allowed them to identify themselves and to be identified by others as 'future surgeons' and to gain access to participation in the surgical world. Participation then enabled further network building and access to careers information in a positive feedback loop. For some, negotiating the hidden curriculum was more difficult, which, for them, rendered a surgical career unattractive or unattainable. CONCLUSIONS: Students perceive a clear surgery-specific hidden curriculum. Using a constructivist grounded theory approach, we have developed a model of how students encounter, uncover and enact this hidden curriculum to succeed. Drawing on concepts of Bourdieu, we discuss unequal access to the hidden curriculum, which was found to exclude many from the possibility of a surgical career.

RESUMEN

Distal nerve transfer is a refined surgical technique involving the redirection of healthy sacrificable nerves from one part of the body to reinstate function in another area afflicted by paralysis or injury. This approach is particularly valuable when the original nerves are extensively damaged and standard repair methods, such as direct suturing or grafting, may be insufficient. As the nerve coaptation is close to the recipient muscles or skin, distal nerve transfers reduce the time to reinnervation. The harvesting of nerves for transfer should usually result in minimal or no donor morbidity, as any anticipated loss of function is compensated for by adjacent muscles or overlapping cutaneous territory. Recent years have witnessed notable progress in nerve transfer procedures, markedly enhancing the outcomes of upper limb reconstruction for conditions encompassing peripheral nerve, brachial plexus and spinal cord injuries.

RESUMEN

BACKGROUND: Root-level suprascapular nerve palsy is commonly reconstructed via spinal accessory nerve transfer in brachial plexus injury, yet some patients fail to recover. We hypothesize that this relates to concomitant undetected lesions distal to the nerve transfer coaptation. METHODS: 67 patients with plexus injury and C5/6 root involvement were included in this prospective study between March 2021 and October 2022. During spinal accessory to suprascapular nerve transfer the entire suprascapular nerve was explored, via cresenteric clavicular osteotomy, and anatomic variations and injury patterns categorized. RESULTS: Proximal root involvement was C5-C6 (n=8), C5-C7 (n=13), C5-C8 (n=17), C5-T1(29). Mean time from injury to surgery was 5.6 months. The suprascapular nerve was found to be injured in 16/67 cases (24%). In 9 cases (13%) the lesion was proximal to the suprascapular fossa. In 3 cases (4%) the suprascapular nerve was injured both proximally and within the fossa, and in 4 cases (6%) in the fossa or distal to it. Therefore, in 7 cases (10%), a traditional suprascapular nerve transfer would not successfully bypass the zone of injury of the suprascapular nerve in the fossa. Of the 16 cases of concomitant suprascapular nerve injury, 1/8 in occurred in C5-C6 root injury, 4/13 of C5-C7 root injury, 5/17 of C5-C8 root injury and 6/39 in total paralysis. CONCLUSIONS: Concomitant distal suprascapular nerve injury in brachial plexus stretch palsy occurred in 24% of the cases. This warrants attention from the surgeon to identify distal lesions and to perform the nerve transfer beyond any secondary lesions.

RESUMEN

OBJECTIVES: Over 60% of UK medical students are female, yet only 33% of applicants to surgical training are women. Role modelling, differing educational experiences and disidentification in female medical students have been implicated in this disparity. We are yet to fully understand the mechanisms that link students' experiences with national trends in career choices. We employ a hitherto unused concept from the theory of communities of practice: paradigmatic trajectories. These are visible career paths provided by a community and are cited by Wenger as potentially the most influential factors shaping the learning of newcomers. We pioneer the use of this theoretical tool in answering the research question: How do paradigmatic trajectories shape female medical students' experiences of surgery and subsequent career intentions? METHODS: This qualitative study comprised a secondary analysis of data sourced from 19 clinical medical students. During individual, in-depth, semi-structured interviews, we explored these students' experiences at medical school. We carried out thematic analysis using sensitising concepts from communities of practice theory, notably that of 'paradigmatic trajectories'. RESULTS: Female students' experiences of surgery were strongly gendered; they were positioned as 'other' in the surgical domain. Four key processes--seeing, hearing, doing and imagining--facilitated the formation of paradigmatic trajectories, on which students could draw when making career decisions. Female students were unable to see or identify with other women in surgery. They heard about challenges to being a female surgeon, lacked experiences of participation, and struggled to imagine a future in which they would be successful surgeons. Thus, based on paradigmatic trajectories constructed from exposure to surgery, they self-selected out of surgical careers. By contrast, male students had experiences of 'hands-in' participation and were not marginalised by paradigmatic trajectories. CONCLUSIONS: The concept of the paradigmatic trajectory is a useful theoretical tool with which to understand how students' experiences shape career decisions. Paradigmatic trajectories within surgery deter female students from embarking on careers in surgery.

RESUMEN

We report a case of a bilateral glass injury to the wrist with transection of flexor tendons and the ulnar nerve and artery in a 60-year-old male patient. Two days after his accident, we repaired all divided structures, and on the right hand, we added the transfer of the opponens motor branch to the deep terminal division of the ulnar nerve aimed at first dorsal interosseous and adductor pollicis muscle reinnervation. After surgery, the patient was followed over 24 months. Postoperative dynamometry of the hand, which included grasping, key-pinch, subterminal-key-pinch, pinch-to-zoom, and first dorsal interosseous muscle strength, indicated recovery only in the nerve transfer side.

RESUMEN

Neuralgia, or nerve pain, is a common presenting complaint for the hand surgeon. When the nerve at play is easily localized, and the cause of the pain is clear (eg, carpal tunnel syndrome), the patient may be easily treated with excellent results. However, in more complex cases, the underlying pathophysiology and cause of neuralgia can be more difficult to interpret; if incorrectly managed, this leads to frustration for both the patient and surgeon. Here we offer a way to conceptualize neuralgia into 4 categories-compression neuropathy, neuroma, painful hyperalgesia, and phantom nerve pain-and offer an illustrative clinical vignette and strategies for optimal management of each. Further, we delineate the reasons why compression neuropathy and neuroma are amenable to surgery, while painful hyperalgesia and phantom nerve pain are not.

RESUMEN

BACKGROUND: Decompression of the superficial sensory branch of the radial nerve (SBRN) with complete brachioradialis tenotomy may treat pain in both simple and complex cases of SBRN compression neuropathy. METHODS: A retrospective chart review was performed of consecutive patients undergoing this procedure between 2008 and 2020 including postoperative outcomes within 90 days. Data were collected and analyzed, including patient and injury demographics, pain descriptors, and patient-reported pain questionnaire, including reported pain severity and impact on quality of life using visual analogue scale (VAS) instruments. Within-group presurgical and postsurgical analyses and between-group statistical analyses were performed. RESULTS: Thirty-three of 58 patients met inclusion criteria. Median time from symptom onset to surgery was 300 days, and median postoperative follow-up time was 37 days. Twenty-five percent of patients ( n = 8) underwent isolated SBRN decompression. The remainder had concomitant decompression of another radial [ n = 16 (48%) or peripheral [ n = 12 (36%)] entrapment point. Ten of 33 patients (30%) had resolution of pain at final follow-up ( P = 0.004). Median change in worst pain over the previous week was -4 ( P < 0.001), and average pain over the last month was -2.75 ( P < 0.001) on the VAS. The impact of pain on quality of life showed a median change of -3 ( P < 0.001) on the VAS. CONCLUSION: Decompression of the sensory branch of the radial nerve including a complete brachioradialis tenotomy improves pain and quality-of-life VAS scores in patients with both simple compression neuropathy syndrome and complex nerve compression syndrome. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

STUDY DESIGN: Case Series. OBJECTIVES: To describe the donor activation focused rehabilitation approach (DAFRA) in the setting of the hand closing nerve transfers in cervical spinal cord injury (SCI) so that therapists may apply it to treatment of individuals undergoing this procedure. SETTING: United States of America-Academic Level 1 Trauma Center. METHODS: We reviewed the records of individuals with cervical SCI who underwent nerve transfer to restore hand closing and post-surgery DAFRA therapy at our institution. The three post-surgery phases of DAFRA included (1) early phase (0-12 months) education, limb preparation, and donor activation exercises, (2) middle phase (12-24 months) volitional recipient muscle activation and (3) late phase (18 + months) strengthening and incorporation of motion in activities of daily living. RESULTS: Subtle gains in hand closing were first observed at a mean of 8.4 months after hand closing nerve transfer surgery. Remarkable improvements including discontinuation of assistive devices, independence with feeding and urinary function, and measurable grip were observed. Function continued to improve slowly for one to two more years. CONCLUSIONS: A deliberate, slow-paced (monthly for >2 years post-surgery) and incremental therapy program-DAFRA-can be used to improve outcomes after nerve transfer to restore hand closing in cervical SCI. SPONSORSHIP: This work was made possible by funding from the Craig H. Neilsen Foundation Spinal Cord Injury Research on the Translation Spectrum (SCIRTS) Grant: Nerve Transfers to Restore Hand Function in Cervical Spinal Cord Injury (PI: Ida Fox).

RESUMEN

BACKGROUND: Since 2007, the authors have performed the triceps-to-axillary nerve transfer using the medial triceps branch to reconstruct axillary nerve function in brachial plexus and isolated axillary nerve palsies. METHODS: A retrospective chart review was undertaken of patients reconstructed with this transfer, recording patient and injury demographics and time to surgery. Preoperative and postoperative function was graded using the Medical Research Council scale and the Disabilities of the Arm, Shoulder, and Hand questionnaire. RESULTS: Postoperatively, 31 patients (64.6 percent) reached Medical Research Council grade 3 or higher at final follow-up. The median Disabilities of the Arm, Shoulder, and Hand score was 59.9 (interquartile range, 38.8 to 70.5) preoperatively and 25.0 (interquartile range, 11.3 to 61.4) at final follow-up. Sixteen patients (33 percent) had isolated axillary nerve injury; the median Medical Research Council grade was 4.25 (interquartile range, 3 to 4.25), with 14 patients (87.6 percent) achieving grade 3 or higher. Thirty-two patients (77 percent) had brachial plexus-associated injury; median Medical Research Council grade was 3 (interquartile range, 2 to 3), with 17 patients (53.1 percent) achieving grade 3 or higher. CONCLUSION: Medial triceps nerve branch is a strong donor for triceps-to-axillary nerve transfer; however, injury factors may limit the motor recovery in this complex patient population, particularly in axillary nerve palsy associated with brachial plexus injury. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

Objective: To understand how COVID-19 has affected the daily lives of people living with cervical spinal cord injury (SCI). Design: Cross sectional qualitative study. Setting: Academic medical center in the Midwestern United States. Participants: Ten community-dwelling individuals (8 men, 2 women), average 11.6 years post-mid-cervical level SCI (N=10). Interventions: Not applicable. Main Outcome Measures: Semistructured interviews were completed by phone. The research team used thematic analysis and inductive strategies to analyze the data in this exploratory investigation. Results: People with cervical SCI living in the United States during the spring of 2020 experienced changes to their daily lives. Participants described how interactions with caregivers for activities of daily living were complicated by fear about contracting and/or transmitting COVID-19. The pandemic limited this population's access to medical care and adversely affected their mental and physical health. Telemedicine was seen as a helpful alternative to in-person visits. Some participants felt that their previous life-altering experience (SCI) better prepared them to cope with the pandemic and "roll with things." Conclusions: Learning about how people with SCI cope, persevere, and survive to overcome adversity during the pandemic should inform future research to support those with SCI. Improving telemedicine and rewarding and recognizing caregivers for their role in maintaining health are important first steps. We must continue to be creative about improving our health care systems and access for people with disabilities, particularly during this and future public health crises.
