Nerve Transfer After Cervical Spinal Cord Injury: Who Has a "Time Sensitive" Injury Based on Electrodiagnostic Findings?

OBJECTIVE: To use the ulnar compound muscle action potential (CMAP) to abductor digiti minimi (ADM) to identify the proportion of individuals with cervical spinal cord injury (SCI) who have lower motor neuron (LMN) abnormalities involving the C8-T1 spinal nerve roots, within 3-6 months, and thus may influence the response to nerve transfer surgery. DESIGN: Retrospective analysis of prospectively collected data. Data were analyzed from European Multicenter Study About SCI database. SETTING: Multi-center, academic hospitals. PARTICIPANTS: We included 79 subjects (age=41.4±17.7, range:16-75; 59 men; N=79), who were classified as cervical level injuries 2 weeks after injury and who had manual muscle strength examinations that would warrant consideration for nerve transfer (C5≥4, C8<3). INTERVENTIONS: None. MAIN OUTCOME MEASURES: The ulnar nerve CMAP amplitude to ADM was used as a proxy measure for C8-T1 spinal segment health. CMAP amplitude was stratified into very abnormal (<1.0 mV), sub-normal (1.0-5.9 mV), and normal (>6.0 mV). Analysis took place at 3 (n=148 limbs) and 6 months (n=145 limbs). RESULTS: At 3- and 6-month post-injury, 33.1% and 28.3% of limbs had very abnormal CMAP amplitudes, respectively, while in 54.1% and 51.7%, CMAPs were sub-normal. Median change in amplitude from 3 to 6 months was 0.0 mV for very abnormal and 1.0 mV for subnormal groups. A 3-month ulnar CMAP <1 mV had a positive predictive value of 0.73 (95% CI 0.69-0.76) and 0.78 (95% CI 0.75-0.80) for C8 and T1 muscle strength of 0 vs 1 or 2. CONCLUSION: A high proportion of individuals have ulnar CMAPs below the lower limit of normal 3- and 6-month post cervical SCI and may also have intercurrent LMN injury. Failure to identify individuals with LMN denervation could result in a lost opportunity to improve hand function through timely nerve transfer surgeries.

Quantifying Tenodesis Hand Function in Cervical Spinal Cord Injury: Implications for Function.

PURPOSE: Cervical spinal cord injury (SCI) has a profound effect on upper-extremity function. Individuals with stiffness and/or spasticity may have more, or less, useful tenodesis function. This study examined the variability present before any reconstructive surgery. METHODS: Tenodesis pinch and grasp were measured with the wrist in maximal active extension. Tenodesis pinch was the contact point of the thumb with the index finger proximal phalanx (T-IF:P1), middle phalanx (T-IF:P2), distal phalanx (T-IF:P3), or absent (T-IF:absent). Tenodesis grasp was the distance from the long finger to the distal palmar crease (LF-DPC). Activities of daily living function was assessed using the Spinal Cord Independence Measure (SCIM). RESULTS: The study included 27 individuals (4 females, 23 males; mean age 36 years, mean time since SCI 6.8 years). The mean International Classification for Surgery of the Hand in Tetraplegia (ICSHT) group classification was 3. In the dominant hand, individuals with a T-IF tenodesis pinch to P1 or P2 had significantly higher total SCIM scores (43.7 and 34.2, respectively) compared to those with absent T-IF tenodesis pinch (SCIM 17.8). Shorter LF-DPC distance with tenodesis grasp (improved finger closing) also correlated with improved SCIM mobility and total scores. No association was found between the ICSHT group and SCIM score or tenodesis measures. CONCLUSIONS: Quantifying tenodesis with pinch (T-IF) and grasp (LF-DPC) is a simple method to characterize hand movement in individuals with cervical SCI. Better tenodesis pinch and grasp were associated with improved activities of daily living performance. CLINICAL RELEVANCE: Differences in grasp function have implications for mobility, and differences in pinch function have implications for all functions, particularly self-care. These physical measurements could be used to assess movement changes after nonsurgical and surgical treatment in tetraplegia.

Clinical electrodiagnostic evaluation for nerve transfer surgery in spinal cord injury: a new indication and clinical pearls.

In this review, we highlight the important role of the clinical electrodiagnostic (EDX) evaluation after cervical spinal cord injury (SCI). Our discussion focuses on the need for timely, frequent, and accurate EDX evaluations in the context of nerve transfer surgery to restore critical upper limb functions, including elbow extension, hand opening, and hand closing. The EDX evaluation is crucial to define the extent of lower motor neuron lesions and determine candidacy for surgery. We also discuss the important role of the postoperative EDX evaluation in determining prognosis and supporting rehabilitation. We propose a practical framework for EDX evaluation in this clinical setting.

Spontaneous Motor Recovery after Cervical Spinal Cord Injury: Issues for Nerve Transfer Surgery Decision Making.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To quantify spontaneous upper extremity motor recovery between 6 and 12 months after spinal cord injury (SCI) to help guide timing of nerve transfer surgery to improve upper limb function in cervical SCI. SETTING: Nineteen European SCI rehabilitation centers. METHODS: Data was extracted from the European Multicenter Study of SCI database for individuals with mid-level cervical SCI (N = 268). Muscle function grades at 6 and 12 months post-SCI were categorized for analysis. RESULTS: From 6 to 12 months after SCI, spontaneous surgically-relevant recovery was limited. Of all limbs (N = 263) with grade 0-2 elbow extension at 6 months, 4% regained grade 4-5 and 11% regained grade 3 muscle function at 12 months. Of all limbs (N = 380) with grade 0-2 finger flexion at 6 months, 3% regained grade 4-5 and 5% regained grade 3 muscle function at 12 months. CONCLUSION: This information supports early (6 month) post-injury surgical consultation and evaluation. With this information, individuals with SCI can more fully engage in preference-based decision-making about surgical intervention versus continued rehabilitation and spontaneous recovery to gain elbow extension and/or hand opening and closing.

Quantifying Donor Deficits Following Nerve Transfer Surgery in Tetraplegia.

PURPOSE: Nerve transfer (NT) surgery can improve function in people with cervical spinal cord injury (SCI). However, the impact of donor nerve deficits remains unclear. The purpose of this study was to quantify donor deficits experienced by individuals with cervical SCI following NT. METHODS: This prospective single-arm, comparative study included people with SCI undergoing upper extremity NTs. Myometry was used to assess muscle strength at baseline and follow-up. The Spinal Cord Independence Measure was used to measure the ability to perform activities of daily living. RESULTS: Ten individuals underwent 20 NTs to restore elbow extension (donor, posterior deltoid; n = 2), hand opening (donor, supinator; n = 7), and hand closing (donor, brachialis; n = 11). Shoulder abduction strength decreased (-5.6% at early and -4.5% late follow-up) in the elbow extension NT. Wrist extension strength decreased at early (-46.9% ± 30.3) and increased by late (76.4% ± 154.0) follow-up in the hand opening NT. No statistically significant change in elbow flexion strength was noted in the hand closing NT. Spinal Cord Independence Measure scores did not change significantly between baseline and early postoperative follow-up; they improved at late follow-up. CONCLUSIONS: Use of expendable donor nerves with redundant function to perform NT surgery has relatively little impact on strength or capacity to perform activities of daily living, even in the unique and highly vulnerable SCI population. Early, temporary loss in wrist extension strength can be seen after the supinator to posterior interosseous nerve transfer. This study offers quantitative data about possible diminution of donor function after NT, enabling hand surgeons to better counsel individuals contemplating upper extremity reconstruction. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic I.

Identifying barriers to upper extremity reconstruction in tetraplegia: a systematic scoping review.

STUDY DESIGN: Systematic scoping review OBJECTIVES: The purpose of this study was to understand the barriers to accessing upper extremity (UE) reconstructive surgery among those living with tetraplegia, and to identify gaps in knowledge. METHODS: Using standardized scoping review methods, a literature search was conducted using four databases and 1069 articles were procured. Two independent reviewers systematically screened the articles in two phases. Retrieved articles underwent thematic analysis using a constructivist grounded theory methodology. RESULTS: The reviewed articles (n = 25) were published between 2002 and 2019, and study designs included: cross-sectional (64%), retrospective (16%), and review articles (8%). Common barriers to UE reconstruction were categorized into factors related to patients, providers, and systems. These general domains included lack of awareness of UE reconstruction and its benefits among people with tetraplegia and providers, poor interdisciplinary working relationships, and a lack of specialized centers that provide these reconstructive surgeries. Specific patient-related barriers related to intrinsic (coping skills, trust, fear) and extrinsic (support network, finances, postoperative course) factors that influenced decision-making. CONCLUSIONS: There are many barriers that prevent individuals with tetraplegia from accessing surgery at different levels of the healthcare system. Establishing specialized centers with strong interdisciplinary working relationships and raising awareness about the advantages and disadvantages of UE reconstruction through peer networks may help to improve accessibility. Using a value-based, patient-centered approach by exploring how individuals with SCI weigh each decision factor when considering surgery may help providers develop treatment options that better align with their goals.

Evaluation of Functional Independence in Cervical Spinal Cord Injury: Implications for Surgery to Restore Upper Limb Function.

PURPOSE: To help individuals make informed choices regarding the optimal type and timing of restorative surgical treatment for cervical spinal cord injury (SCI), more precise information is needed on their ability to perform activities of daily living. The goal of this work was to describe functional independence achieved by individuals with differing levels of cervical SCI. METHODS: Using the comprehensive European Multicenter Study of Spinal Cord Injury dataset, analysis was undertaken of individuals with traumatic SCI, motor-level C5-C8. Data on feeding, bladder management, and transfers (bed to wheelchair) were compared between individuals with different levels of injury. Subgroup analyses of symmetrical and asymmetrical SCI and between complete and incomplete SCI were performed. The impact of age, sex, and time postinjury on functional independence was ascertained. RESULTS: Data were available for individuals with symmetrical (n = 204) and asymmetrical (n = 95) patterns of SCI. Independence with feeding, urinary function, and transfer ability was increased in individuals with strong finger flexion. Unexpectedly, the presence of strong elbow extension did not uniformly result in the ability to transfer independently. There was no change in any of the analyzed activities between 6 and 12 months postinjury. CONCLUSIONS: People with cervical SCI who gain finger flexion have greater independence with feeding, urinary, and transfer activities. Restoration of finger flexion should be a reconstructive priority for individuals with midcervical-level SCI. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Video-based Learning in Surgery: Establishing Surgeon Engagement and Utilization of Variable-duration Videos.

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.

Development and Validation of a Prognostic, Risk-Adjusted Scoring System for Operative Upper-Extremity Infections.

PURPOSE: Acute infections of the distal upper extremity (UE) can require one and possibly multiple debridements. We aimed to develop and validate a prognostic scoring system based on patient, infection, and microbiology risk factors to help with operative planning and patient counseling. METHODS: We studied all acute surgical UE infections distal to the elbow joint over a 5-year period. A split-sample design was created with 1:1 randomization into development and validation samples. The primary outcome was infection persistence, defined as the need for additional operative drainage according to usual indications. Multivariable logistic regression identified risk factors for persistent infections in the development sample, which was translated to a simple clinical scoring system derived from regression coefficients. The model was then tested separately against the validation sample. RESULTS: A total of 602 patients were included; 31% of all infections exhibited persistence. Independent risk factors from the development sample included diabetes (3 points), smoking (2 points), leukocytosis at presentation (2 points), animal bite mechanism (3 points), osteomyelitis (4 points), tenosynovitis (7 points), pyarthrosis (3 points), necrotizing fasciitis (11 points), and methicillin-resistant Staphylococcus aureus (3 points). These were all confirmed in the validation sample. Infections were categorized into 3 groups based on risk for persistent infection: low (less than 8 points), medium (8-11 points), and high (12 points or more). In the validation sample, the probability of persistent infection for these 3 groups was 23%, 57%, and 79%, respectively. The c statistic for the model in the validation sample was 0.79. CONCLUSIONS: Persistence of acute surgical distal UE infections is mediated by patient and microbiology factors, as well as infection mechanism and type. Surgeons can use this risk-adjusted prognostic scoring system to anticipate which infections may require additional therapeutic debridement and plan operative schedules and counsel patients accordingly. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Evaluation for Late Nerve Transfer Surgery in Spinal Cord Injury: Predicting the Degree of Lower Motor Neuron Injury.

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.

Development of a Risk Prediction Model to Individualize Risk Factors for Surgical Site Infection After Mastectomy.

BACKGROUND: Little data are available regarding individual patients' risk of surgical site infection (SSI) following mastectomy with or without immediate reconstruction. Our objective was to develop a risk prediction model for mastectomy-related SSI. METHODS: Using commercial claims data, we established a cohort of women <65 years of age who underwent a mastectomy from 1 January 2004-31 December 2011. International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes were used to identify SSI within 180 days after surgery. SSI risk factors were determined with multivariable logistic regression using derivation data from 2004-2008 and validated with 2009-2011 data using discrimination and calibration measures. RESULTS: In the derivation cohort, 595 SSIs were identified in 7607 (7.8 %) women, and 396 SSIs were coded in 4366 (9.1 %) women in the validation cohort. Independent risk factors for SSIs included rural residence, rheumatologic disease, depression, diabetes, hypertension, liver disease, obesity, pre-existing pneumonia or urinary tract infection, tobacco use disorder, smoking-related diseases, bilateral mastectomy, and immediate reconstruction. Receipt of home healthcare was associated with lower risk. The model performed equally in the validation cohort per discrimination (C-statistics 0.657 and 0.649) and calibration (Hosmer-Lemeshow p = 0.091 and 0.462 for derivation and validation, respectively). Three risk strata were created based on predicted SSI risk, which demonstrated good correlation with the proportion of observed infections in the strata. CONCLUSIONS: We developed and internally validated an SSI risk prediction model that can be used to counsel women with regard to their individual risk of SSI post-mastectomy. Immediate reconstruction, diabetes, and smoking-related diseases were important risk factors for SSI in this non-elderly population of women undergoing mastectomy.

THE EPIDEMIOLOGY AND OUTCOMES OF BREAST CANCER SURGERY.

We studied women after breast-conserving surgery and mastectomy with immediate (IR) and delayed reconstruction to determine the risk of surgical site infections (SSIs). The SSI rate was 1.3% for BCS, 5.2% for mastectomy, and 10.3% for mastectomy plus IR with flap. SSI risk was higher for mastectomy and IR with implantation versus delayed reconstruction with implantation (8.8% versus 5.9%, P = 0.039) or staged reconstruction with implantation (3.3%, P <0.001). Women with SSI had more SSIs after second-staged reconstruction and implantation compared to those without SSI (10.9% versus 2.7%, P <0.001). SSI was first coded 2 to 30 days postoperatively in 50.3%, and 23% between 31 and 60 days postoperatively. The noninfectious wound complication rate was 10.8%. The noninfectious wound complication rate was 5.8% after mastectomy, 13.4% after mastectomy with implantation, 18.7% after mastectomy with flap, and 15.2% with mastectomy flap and implantation (P <0.001). Implants were removed within 60 days in 6% of mastectomies with implantation.

Direct radial to ulnar nerve transfer to restore intrinsic muscle function in combined proximal median and ulnar nerve injury: case report and surgical technique.

A distal median to ulnar nerve transfer for timely restoration of critical intrinsic muscle function is possible in isolated ulnar nerve injuries but not for combined ulnar and median nerve injuries. We used a distal nerve transfer to restore ulnar intrinsic function in the case of a proximal combined median and ulnar nerve injury. Transfer of the nonessential radial nerve branches to the abductor pollicis longus, extensor pollicis brevis, and extensor indicis proprius to the motor branch of the ulnar nerve was performed in a direct end-to-end fashion via an interosseous tunnel. This method safely and effectively restored intrinsic function before terminal muscle degeneration.

The Yearly Periodicity of Operative Upper Extremity Trauma: A Retrospective Study of "Trauma Season".

BACKGROUND: Upper extremity (UE) trauma requiring operative care increases during the summer and fall months, which the authors colloquially refer to as "trauma season." METHODS: CPT databases were queried for codes related to acute UE trauma at a single level-1 trauma center. Monthly CPT code volume was tabulated for 120 consecutive months and average monthly volume was calculated. Raw data were plotted as a time series and transformed as a ratio to the moving average. Autocorrelation was applied to the transformed data set to detect yearly periodicity. Multivariable modeling quantified the proportion of volume variability attributable to yearly periodicity. Subanalysis assessed presence and strength of periodicity in four age groups. RESULTS: A total of 11,084 CPT codes were included. Monthly trauma-related CPT volume was highest in July through October and lowest in December through February. Time-series analysis revealed yearly oscillation in addition to a growth trend. Autocorrelation revealed statistically significant positive and negative peaks at a lag of 12 and 6 months, respectively, confirming yearly periodicity. Multivariable modeling revealed R 2 attributable to periodicity of 0.53 ( P < 0.01). Periodicity was strongest in younger populations and weaker in older populations. R 2 was 0.44 for ages 0 to 17, 0.35 for ages 18 to 44, 0.26 for ages 45 to 64, and 0.11 for ages 65 and older. CONCLUSIONS: Operative UE trauma volumes peak in the summer and early fall and reach a winter nadir. Periodicity accounts for 53% of trauma volume variability. The authors' findings have implications for allocation of operative block time and personnel and expectation management over the course of the year.

Escalating Surgical Treatment for Left Ventricular Assist Device Infection and Expected Mortality: Clinical Risk Prediction Score.

BACKGROUND: Left ventricular assist devices (LVAD) improve survival for patients with cardiac failure, but LVAD-specific infection (VSI) remains a challenge with poorly understood predictive risk factors. The indications and use of escalating medical treatment to surgical debridement and potential flap reconstruction are not well characterized. STUDY DESIGN: A retrospective review of consecutive patients undergoing primary LVAD implantation at a tertiary academic center was performed. The primary outcome measures were 90-day and overall mortality after VSI. Cox proportional hazards regression was used to generate a risk prediction score for mortality. RESULTS: Of the 760 patients undergoing primary LVAD implantation, 255 (34%) developed VSI; of these patients, 91 (36%) were managed medically, 134 (52%) with surgical debridement, and 30 (12%) with surgical debridement and flap reconstruction. One-year survival after infection was 85% with median survival of 2.40 years. Factors independently associated with increased mortality were diabetes (hazard ratio [HR] 1.44, p = 0.04), MRSA infection (HR 1.64, p = 0.03), deep space (pump pocket or outflow cannula) involvement (HR 2.26, p < 0.001), and extracorporeal membrane oxygenation after LVAD (HR 2.52, p < 0.01). Factors independently associated with decreased mortality were flap reconstruction (HR 0.49, p = 0.02) and methicillin-sensitive Staphylococcus aureus infection (HR 0.63, p = 0.03). A clinical risk prediction score was developed using these factors and showed significant differences in median survival, which was 5.67 years for low-risk (score 0 to 1), 3.62 years for intermediate-risk (score 2), and 1.48 years for high-risk (score ≥3; p < 0.001) patients. CONCLUSIONS: We developed a clinical risk prediction score to stratify patients with VSI. In selected cases, escalating surgical treatment was associated with increased survival. Future work is needed to determine whether early surgical debridement and flap reconstruction can alter outcomes in select cases of VSI.

Upper Extremity Surgery in Cervical Spinal Cord Injury: A Prospective Comparative Mixed Methods Study.

BACKGROUND: Cervical spinal cord injury (SCI) is a devastating injury. Restoring upper extremity function is a top priority, which can be accomplished by tendon transfer (TT) and nerve transfer (NT) surgeries. The purpose of this prospective comparative study was to assess long-term changes in UE function between surgical (TT or NT) and non-surgical groups through a comprehensive mixed methods approach. METHODS: This multicenter, cohort study compared data among three groups: those undergoing 1) no surgery 2) TT surgery, or 3) NT surgery. Quantitative data, the Spinal Cord Independence Measure (SCIM) and Short Form Health Survey (SF-36), was collected at baseline and long-term follow-up (6-24 months). Qualitative semi-structured interview data was also obtained from these participants and their identified caregivers at baseline, early follow-up (1 month), and long-term follow-up (6-24 months). RESULTS: Thirty-one participants had quantitative data across all timepoints: no surgery (n=14), TT (n=7), and NT (n=10). SCIM scores improved in TT and NT groups compared to the no surgery group (p<0.05). SF-36 scores did not differ among groups. Qualitative data analysis (n=168 interviews) corroborated SCIM findings: surgical participants and their caregivers reported improvement in transfers and ability to perform activities of daily living, including grooming and self-catheterization. Improved use of electronics and ability to operate a motor vehicle were also reported. Post-operative therapy was identified as a critical component of achieving gains. CONCLUSION: Both TT and NT surgery leads to quantitative and qualitative functional gains as compared to the no surgery group. This comparative information should be used to help surgeons discuss treatment options.

Comparing surgeries to restore upper extremity function in tetraplegia: Impact on function during the perioperative period.

CONTEXT/OBJECTIVE: To assess short-term changes in health outcomes in people with cervical-level spinal cord injury (SCI) who underwent upper extremity (UE) reconstruction via either novel nerve transfer (NT) or traditional tendon transfer (TT) surgery with individuals who did not undergo UE surgical reconstruction. DESIGN: Prospective, comparative cohort pilot study. PARTICIPANTS: 34 participants with cervical SCI met the following inclusion criteria: age 18 or older, greater than 6 months post-injury, and mid-cervical level SCI American Spinal Injury Association Impairment Scale (AIS) A, B or C. SETTING: Two tertiary academic hospitals and their affiliated veterans' hospitals. METHODS: Health outcomes were assessed using two previously validated measures, the Spinal Cord Independence Measure (SCIM) and Short-Form Health Survey (SF-36). Demographic, surgical, and survey data were collected at the initial evaluation and one month postoperatively/post-baseline. RESULTS: 34 participants with cervical SCI were recruited across three cohorts: no surgery (n = 16), NT (n = 10), and TT (n = 8). The TT group had a decline in SCIM and SF-36 scores whereas the NT and no surgery groups experienced little change in independence or health status in the immediate perioperative period. CONCLUSIONS: Surgeons and rehabilitation providers must recognize differences in the perioperative needs of people with cervical SCI who chose to have restorative UE surgery. Future work should focus on further investigation of health outcomes, change in function, and improving preoperative counseling and cross-disciplinary management.

Assessing an Online Patient Decision Aid about Upper Extremity Reconstructive Surgery for Cervical Spinal Cord Injury: Pilot Testing Knowledge, Decisional Conflict, and Acceptability.

Background. While nerve and tendon transfer surgery can restore upper extremity function and independence after midcervical spinal cord injury, few individuals (∼14%) undergo surgery. There is limited information regarding these complex and time-sensitive treatment options. Patient decision aids (PtDAs) convey complex health information and help individuals make informed, preference-consistent choices. The purpose of this study is to evaluate a newly created PtDA for people with spinal cord injury who are considering options to optimize upper extremity function. Methods. The PtDA was developed by our multidisciplinary group based on clinical evidence and the Ottawa Decision Support Framework. A prospective pilot study enrolled adults with midcervical spinal cord injury to evaluate the PtDA. Participants completed surveys about knowledge and decisional conflict before and after viewing the PtDA. Acceptability measures and suggestions for further improvement were also solicited. Results. Forty-two individuals were enrolled and completed study procedures. Participants had a 20% increase in knowledge after using the PtDA (P < 0.001). The number of participants experiencing decisional conflict decreased after viewing the PtDA (33 v. 18, P = 0.001). Acceptability was high. To improve the PtDA, participants suggested adding details about specific surgeries and outcomes. Limitations. Due to the COVID-19 pandemic, we used an entirely virtual study methodology and recruited participants from national networks and organizations. Most participants were older than the general population with a new spinal cord injury and may have different injury causes than typical surgical candidates. Conclusions. A de novo PtDA improved knowledge of treatment options and reduced decisional conflict about reconstructive surgery among people with cervical spinal cord injury. Future work should explore PtDA use for improving knowledge and decisional conflict in the nonresearch, clinical setting. Highlights: People with cervical spinal cord injury prioritize gaining upper extremity function after injury, but few individuals receive information about treatment options.A newly created patient decision aid (PtDA) provides information about recovery after spinal cord injury and the role of traditional tendon and newer nerve transfer surgery to improve upper extremity upper extremity function.The PtDA improved knowledge and decreased decisional conflict in this pilot study.Future work should focus on studying dissemination and implementation of the ptDA into clinical practice.

Surgery to restore upper extremity function in tetraplegia-Preferences for early and frequent access to information.

INTRODUCTION: People with cervical spinal cord injury (SCI) identify improving upper extremity (UE) function as a top priority. In addition to comprehensive rehabilitation, UE surgeries, including nerve and tendon transfers, enhance function. However, barriers exist to disseminating information about surgical options to enhance UE function. OBJECTIVE: To assess the experiences and preferences of people with cervical SCI and their caregivers in accessing information about surgery to enhance UE function. DESIGN: Prospective cohort study. Participants were followed up for 24 months and completed up to three interviews. SETTING: Tertiary care at academic and affiliated Veterans Administration Health Care Centers. PARTICIPANTS: Adults with cervical SCI (n = 35) ages 18 to 80 years with mid-cervical SCI American Spinal Injury Association Impairment Scale A, B, or C (at least 6 months post-injury) and their caregivers (n = 23) were eligible to participate. Participants were enrolled in three groups: nerve transfer, tendon transfer, or no UE reconstructive surgery. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Semi-structured interviews about surgical knowledge and experiences. RESULTS: Data were analyzed and three themes were identified. First, providing information about UE surgical options early post-injury was recommended. The acute or inpatient rehabilitation phases of recovery were the preferred times to receive surgical information. Second, challenges with information dissemination were identified. Participants learned about UE surgery through independent research, medical provider interactions, or peers. Third, peers were identified as valuable resources for SCI needs and surgical information. CONCLUSIONS: Following cervical SCI, information about UE reconstructive surgeries should be a standard component of education during rehabilitation. An increased understanding of the reconstructive options available to improve UE function is necessary to educate stakeholders. Future research is needed to support the development of strategies to effectively present surgical information to individuals with SCI and health care providers.
