Background Reconstructive surgery for upper extremity manifestations of cerebral palsy (CP) has been demonstrated to be safe and effective, yet many potential candidates are never evaluated for surgery. The purpose of this study was to determine barriers to upper extremity reconstruction for patients with CP in a cohort of upper extremity surgeons and nonsurgeons. Methods We sent a questionnaire to 4167 surgeons and nonsurgeon physicians, aggregated responses, and analyzed for differences in perceptions regarding surgical efficacy, patient candidacy for surgery, compliance with rehabilitation, remuneration, complexity of care, and physician comfort providing care. Results Surgeons and nonsurgeons did not agree on the literature support of surgical efficacy (73% vs 35% agree or strongly agree, respectively). Both surgeons and nonsurgeons felt that many potential candidates exist, yet there was variability in their confidence in identifying them. Most surgeons (59%) and nonsurgeons (61%) felt comfortable performing surgery and directing the associated rehabilitation, respectively. Neither group reported that patient compliance, access to rehabilitation services, and available financial resources were a major barrier, but surgeons were more likely than nonsurgeons to feel that remuneration for services was inadequate (37% vs 13%). Both groups agreed that surgical treatments are complex and should be performed in the setting of a multidisciplinary team. Conclusions Surgeons and nonsurgeons differ in their views regarding upper extremity reconstructive surgery for CP. Barriers to reconstruction may be addressed by performing higher level research, implementing multispecialty educational outreach, developing objective referral criteria, increasing surgical remuneration, improving access to trained upper extremity surgeons, and implementing multidisciplinary CP clinics.

Summary Background Understanding the morbidity of sural nerve harvest is important when counselling patients regarding nerve grafts. Existing data consist of small studies with varying degrees of follow-up and a wide range of reported donor site outcomes. The objective of this study was to systematically review the literature and pool the current data for postoperative outcomes after sural nerve graft harvest. Methods A systematic review of literature was conducted to identify studies that examined donor site outcomes of sural nerve graft harvests. Results Five-hundred and fourteen studies were identified through a literature search, and nine studies met inclusion criteria. There were 240 patients who underwent sural nerve grafts. The most common methods for sensory evaluation were patient survey (44.4%) and Semmes–Weinstein evaluation (33.3%). Five studies reported surface areas of sensory loss, and this generally decreased over time after sural nerve grafting. Overall, 87.2% of patients (n = 190) reported sensory loss, 25.6% (n = 42) of patients reported pain, 22.2% (n = 28) of patients reported cold sensitivity, and 10% (n = 20) of patients reported functional impairment at follow-up. When the proximal sural nerve was spared during harvest, the extent of sensory loss and pain were less than harvest at the popliteal fossa (87.4% vs 95.7%, p = 0.0407 and 9.1% vs 35.5%, p = 0.0004, respectively). Conclusions In this study, we present the extent of sensory loss and rates of pain, cold sensitivity, and functional impairment after sural nerve harvest. These data should be discussed prior to surgery in order for patients and surgeons to make an informed decision.

We present a unique case of side-to-side metacarpal fusion for reconstruction after an isolated gunshot wound to the right hand of a 19-year-old woman. There was a traumatic segmental loss of the proximal right second metacarpal base with considerable comminution of the trapezium and trapezoid. Reconstructive options were limited because of the destruction of the distal carpus and carpometacarpal (CMC) joint. Digital ray amputation was offered but deferred because of patient preference. The reconstruction was performed via metacarpal fusion of the second metacarpal remnant to the third metacarpal base, bypassing the previously destroyed second CMC joint. The fusion of the second and third metacarpals offers acceptable results when the radial CMC joints are traumatized with extensive bone loss.

Background The purpose of this study was to determine the impact of upper extremity peripheral nerve blocks on emergency department (ED) utilization after hand and upper extremity surgery. Methods We reviewed all outpatient upper extremity surgeries performed in a single Midwestern state between January 2009 and June 2019 using the Indiana Network for Patient Care. These encounters were used to develop a database of patient demographics, comorbidities, concurrent procedures, and postoperative ED visit utilization data. We performed univariate, bivariate, and multivariate logistic regression analyses. Results Among 108 451 outpatient surgical patients, 9079 (8.4%) received blocks. Within 1 week of surgery, a greater proportion of patients who received peripheral nerve blocks (1.4%) presented to the ED than patients who did not (0.9%) ( P < .001). The greatest risk was in the first 2 postoperative days (relative risk, 1.78; P < .001). Pain was the principal reason for ED utilization in the block cohort (53.6%) compared with those who did not undergo a block (35.1%) ( P < .001). When controlling for comorbidities and demographics, only peripheral nerve blocks (adjusted odds ratio [OR], 1.71; P = 0.007) and preprocedural opioid use (adjusted OR, 1.43; P = .020) conferred an independently increased risk of ED utilization within the first 2 postoperative days. Conclusions Peripheral nerve blocks used for upper extremity surgery are associated with a higher risk of unplanned ED utilization, most likely related to rebound pain. Through proper patient education and pain management, we can minimize this unnecessary resource utilization.

Lymphedema is progressive arm swelling from lymphatic dysfunction which can occur in 30% patients undergoing axillary dissection/radiation for breast cancer. Immediate lymphatic reconstruction (ILR) is performed in an attempt decrease the risk of lymphedema in patients undergoing axillary lymph node dissection (ALND). The purpose of this study was to assess the efficacy of ILR in preventing lymphedema rates in ALND patients. An institutional review board-approved retrospective review was performed of all patients who underwent ILR from 2017 to 2019. Patient demographics, comorbidities, operative and pathologic findings, number of LVAs, limb measurements, complications, and follow-up were recorded and analyzed. Student’s sample t-test, Fisher’s exact test, and ANOVA were used to analyze data; significance was set at p < 0.05. Thirty-three patients were included in this analysis. Three patients (9.1%) developed persistent lymphedema, and two patients (6.1%) developed transient arm edema that resolved with compression and massage therapy. A significant effect was found for body mass index and the number of lymph nodes taken on the development of lymphedema (p < 0.01). The rate of lymphedema in this series was 9.1%, which is an improvement from historical rates of lymphedema. Our findings support ILR as a technique that potentially decreases the incidence of lymphedema after axillary lymphadenectomy. Obesity and number of lymph nodes removed were significant predictive variables for the development of lymphedema following LVA.

Rhinophyma is an advanced stage of rosacea affecting the nasal soft tissues and resulting in disruption of the nasal architecture, airway obstruction, and disfigurement of the nasal aesthetic units. Rhinophyma presents with hypertrophy of the nasal soft tissues, erythema, telangiectasias, nodules, and lobules with a bulbous appearance. Significant psychosocial morbidity is associated with the disease. Understanding of this disease has improved and multiple treatment options exist. The article is a review of the literature to evaluate the pathophysiology, clinical presentation, and epidemiology of keywords "rhinophyma" and "rosacea" using an OVID Medline and PubMed search along with a systematic review of outcomes pertaining to treatment of rhinophyma with laser therapy, scalpel excision, and the subunit method using an OVID Medline search. The subunit method has the highest complication and revision rates followed by carbon dioxide laser therapy. Outcomes between carbon dioxide laser and scalpel therapy and electrocautery are equivalent. Scalpel excision is a more cost-effective treatment modality with less post-operative complications; however, it risks poor hemostasis intraoperatively. Patient satisfaction is common post-therapy regardless of the treatment method. Over 89% of patients would recommend undergoing treatment for rhinophyma irrespective of treatment type. Treatment options vary, and choice of treatment can be dependent on practitioner and patients' treatment goals.

Background Anastomotic couplers expedite venous microvascular anastomoses and have been established as an equivalent alternative to hand-sewn anastomoses. However, complications unique to the coupler such as palpability and extrusion can occur. The purpose of this study was to perform a systematic review of the literature to assess complications distinct to the venous anastomotic coupler. Methods A Medline, PubMed, EBSCO host search of articles involving anastomotic venous couplers was performed. Studies involving arterial anastomotic couplers, end-to-side anastomoses, and reviews were excluded. Data points of interest were flap failure, venous thrombosis, hematoma, partial flap necrosis, infection, coupler extrusion, and coupler palpability. Results The search identified 165 articles; 41 of these met inclusion criteria. A total of 8,246 patients underwent 8,955 venous-coupled anastomoses. Combined reoperation rate was 3.3% and all-cause unsalvageable flap failure was 1.0%. Complications requiring reoperation included venous thrombosis (2.0%), hematoma (0.4%), partial flap necrosis (0.4%), and infection (0.3%). Eight patients had palpable couplers and 11 patients had extrusion of couplers (head/neck, hand, and feet) and required operative management. Conclusion Venous couplers remain an equivalent alternative to conventional hand-sewn anastomosis. However, venous coupler extrusion and palpability in the late postoperative period is a complication unique to anastomotic couplers, particularly in radiated head and neck, feet and hand free flaps. Removing extruded venous couplers is safe after tissue integration 3 weeks postoperatively. Coupler palpability and extrusion should be integrated into preoperative patient counseling and assessed in follow-up examinations.

General Engineering - Abstract
Background Brachial artery lacerations are limb-threatening injuries requiring emergent repair. Concomitant peripheral nerve symptoms are often only identified postoperatively. This study evaluated the prevalence of peripheral nerve deficits among this population as the indications for early nerve exploration have not been definitively established. Methods We reviewed all patients sustaining a brachial artery injury at one pediatric and two adult Level I Trauma Centers between January 1, 2007, and December 31, 2017. We recorded patient demographics, comorbidities, intoxication status, injury mechanism, concomitant injuries, type of repair, and intraoperative peripheral nerve exploration findings. Pre-and post-operative and long-term peripheral nerve function examination findings were analyzed. Differences between categorical variables were determined with Chi-square and Fisher's exact tests. Results Thirty-four patients sustained traumatic brachial artery lacerations requiring operative repair. Injury mechanisms included tidy (clean cut) laceration (n=11, 32%), gunshot wound (n=9, 26%), blunt trauma (n=8, 24%), and untidy laceration (n=6, 18%). Preoperatively, 15% had a normal peripheral nerve examination, 26% had localizable symptoms, 38% had non-localizable symptoms, and 21% were taken to the operating room without formal nerve assessment. Thirty-two percent underwent formal nerve exploration, and 81% underwent nerve repair. At an average follow-up of 2.5 years, 27% of patients underwent exploration, and 39% did not have localizable peripheral nerve deficits (

Type B ulnar polydactyly is a common congenital hand difference and can be treated with either ligation or surgical excision. There is a paucity of literature, however, evaluating long-term patient reported outcomes of these treatments. The purpose of this study was to compare the long-term outcomes after ligation and excision for the management of type B ulnar polydactyly.We created a database of patients who underwent treatment for type B ulnar polydactyly at a single pediatric health system from 2005 to 2014. We administered the Patient Reported Outcomes Measurement Information System (PROMIS) Pediatric Upper Extremity survey to patients through telephone and assessed for their satisfaction.We successfully collected outcomes from 69 of 173 eligible patients treated in infancy (40% response rate). The mean follow-up was 11.1±2.5 years, and the average age of the participant at the time of the survey was 11.7±2.6 years of age. Twenty-four patients were treated with in-office ligation and 45 underwent formal surgical excision. Ten patients who were initially treated with ligation required future treatment with surgery because of symptomatic neuroma stump or persistent polydactyly (42%). Patients who were treated with surgical excision rated significantly higher satisfaction with their treatment than those who underwent ligation (P=0.003). Patients in both cohorts rated similar satisfaction with the esthetic appearance of their hand (P=0.07). There was no significant difference in PROMIS-rated hand function between the ligation and surgical cohort (P=0.765) and treated adolescents PROMIS scores were not statistically different than age-matched controls without polydactyly.While ligation and surgical excision result in similar function and esthetics, patient satisfaction is higher after surgery. Furthermore, a significant number of patients fail ligation and ultimately undergo surgery for symptomatic neuroma or persistent polydactyly. Counseling parents of patients with type B ulnar polydactyly should include these considerations to assist them in selecting the best treatment for their child.Level III.

General Engineering - Abstract
Background In this study, we sought to determine if postoperative physician phone calls following hand and wrist fracture surgery improve patient outcomes, satisfaction, and treatment adherence. Methodology We prospectively enrolled 24 consecutive adult patients who underwent outpatient surgery for isolated hand and wrist fractures at a single, metropolitan, safety-net hospital over one year to receive an additional physician phone call starting on postoperative day one. We measured preoperative and postoperative Brief Michigan Hand Questionnaire (bMHQ) composite score, overall satisfaction on a five-point Likert scale, compliance with treatment recommendations, presence of complications, discharge instructions reading level, and clarity of discharge and follow-up instructions. The surgical team was blinded to the treatment arm. Results The bMHQ score improved 26% after surgery; however, there was no difference in absolute score change between groups (12.2 vs. 6.5, p = 0.69). Most patients were satisfied throughout all stages of care, but postoperative satisfaction did not differ between groups (1.4 vs. 2.5, p = 0.21). There was a stronger correlation between patient hand function and satisfaction starting one month after surgery (R

Background: Carpal tunnel release (CTR) is one of the most commonly performed procedures in hand surgery. Complications from surgery are a rare but significant patient dissatisfier. The purpose of this study was to determine whether insurance status is independently associated with complications after CTR. Methods: We retrospectively identified all patients undergoing CTR between 2008 and 2018 using the Indiana Network for Patient Care, a state-wide health information exchange, and built a database that included patient demographics and comorbidities. Patients were followed for 90 days to determine whether a postoperative complication occurred. To minimize dropout, only patients with 1 year of encounters after surgery were included. Results: Of the 26 151 patients who met inclusion criteria, 2662 (10.2%) had Medicare, 7027 (26.9%) had Medicaid, and 16 462 (62.9%) had commercial insurance. Compared with Medicare, Medicaid status ( P < .001) and commercial insurance status ( P < .001) were independently associated with postoperative CTR complications. The overall complication rate was 2.23%, with infection, wound breakdown, and complex regional pain syndrome being the most common complications. Younger age, alcohol use, diabetes mellitus, hypertension, and depression were also independently associated with complications. Conclusions: The incidence of complications after CTR is low. Insurance status, patient demographics, and medical comorbidities, however, should be evaluated preoperatively to appropriately risk stratify patients. Furthermore, surgeons can use these data to initiate preventive measures such as working to manage current comorbidities and lifestyle choices, and to optimize insurance coverage.

This study aimed to understand the current utilization of surgical approaches for nerve ending management in upper extremity amputation to prevent and treat nerve-related pain. We administered a survey to 190 of 1270 surgeons contacted by email (15% response rate) and analyzed their demographics, practice patterns, and perceptions regarding techniques for nerve ending management in upper extremity amputees. Although many surgical techniques were employed, most surgeons (54%) performed traction neurectomy during amputation and, alternatively, bury nerve into muscle if a neuroma subsequently develops (52%). Surgeons in practice less than 10 years were more likely to perform targeted muscle reinnervation (TMR) and regenerative peripheral nerve interfaces (RPNI) than surgeons in practice greater than 10 years (p0.001). TMR and RPNI were performed more frequently for proximal amputations than distal amputations, but there is no consensus regarding the optimal timing to utilize these techniques. Surgeons commonly cited improved prosthetic control, pain, and phantom limb symptoms as reasons for performing TMR and RPNI. Increased physician compensation as a consideration was more commonly cited among TMR non-adopter than adopters (31% vs 14%, p=0.008). There is no consensus regarding techniques for the prevention or treatment of nerve ending pain in upper extremity amputees. TMR and RPNI are being utilized with increasing frequency and both patient and surgeon factors affect implementation in clinical practice.

Introduction: Type B ulnar polydactyly is one of the most commonly encountered congenital hand differences and can be treated with either suture ligation or surgical excision. The purpose of this study was to determine what factors families consider in selecting treatment for their child with type B ulnar polydactyly. Methods: We developed an ad-hoc survey instrument for parents of children with type B ulnar polydactyly that assessed motivation for choosing treatment, parent-reported outcomes, and overall satisfaction. Face validity was confirmed with a think-out-loud protocol using 5 test subjects. We administered surveys via telephone after treatment was complete. We assessed for differences between the cohort who chose in-office suture ligation versus the cohort who opted for operating-room excision using Chi square and Fischer exact tests for categorical variables and Student t-test for continuous variables. Results: Seventy of the 156 parents of consecutive patients contacted agreed to participate (45% response rate), with a mean follow-up of 2.25 years. Twenty-eight chose in-office suture ligation and 42 chose surgical excision. Rapid treatment was prioritized more often in those who selected suture ligation than in those who opted for surgical excision (p=0.044). The complication rate for suture ligation was significantly higher than for surgical excision (p

Hand surgery dogma suggests that simultaneous surgical treatment of carpal tunnel syndrome and Dupuytren's contracture results in an increased incidence of complex regional pain syndrome. As a result, many surgeons do not perform surgery for the two conditions concurrently. The authors' goal was to determine the extent of this association.The authors identified all patients undergoing surgical treatment for carpal tunnel syndrome, Dupuytren's contracture, or both between April of 1982 and March of 2017 using the Indiana Network for Patient Care, a large, multi-institutional, statewide information exchange. Demographics, comorbidities, and 1-year postoperative incidence of complex regional pain syndrome were recorded.A total of 51,739 patients (95.6 percent) underwent carpal tunnel release only, 2103 (3.9 percent) underwent palmar fasciectomy only, and 305 (0.6 percent) underwent concurrent carpal tunnel release and palmar fasciectomy. There was no difference in the likelihood of developing complex regional pain syndrome (p = 0.163) between groups. Independent risk factors for developing complex regional pain syndrome were younger age; anxiety; depression; epilepsy; gout; and history of fracture of the radius, ulna, or carpus.Concurrent carpal tunnel release and palmar fasciectomy is not associated with an increased risk for developing complex regional pain syndrome. Patient demographics, medical comorbidities, and a history of upper extremity trauma are associated with the development of complex regional pain syndrome after surgery and should be discussed preoperatively as potential risk factors.Therapeutic, III.

Background: Many patients with complete nerve lacerations after upper extremity trauma have a documented normal peripheral nerve examination at the time of initial evaluation. The purpose of this study was to determine whether physician-, patient-, and injury-related factors increase the risk of false-negative nerve examinations. Methods: A statewide health information exchange was used to identify complete upper extremity nerve lacerations subsequently confirmed by surgical exploration at 1 pediatric and 2 adult level I trauma centers in a single city from January 2013 to January 2017. Charts were manually reviewed to build a database that included Glasgow Coma Scale score, urine drug screen results, blood alcohol level, presence of concomitant trauma, type of injury, level of injury, laterality, initial provider examination, and initial specialist examination. Bivariate and multivariable analyses were performed to evaluate risk factors for a false-negative examination. Results: Two hundred eighty-eight patients met inclusion criteria. The overall false-negative examination rate was 32.5% at initial encounter, which was higher among emergency medicine physicians compared with extremity subspecialists ( P < .001) and among trauma surgeons compared with surgical subspecialists ( P = .002). The false-negative rate decreased to 8% at subsequent encounter ( P < .001). Risk factors for a false-negative nerve examination included physician specialty, a gunshot wound mechanism of injury, injury at the elbow, and age greater than 71 years. Conclusion: There is a high false-negative rate among upper extremity neurotmesis injuries. Patients with an injury pattern that may lead to nerve injury warrant prompt referral to an upper extremity specialist in an effort to optimize outcomes.

Recovery after an upper extremity peripheral nerve injury varies depending on multiple factors. In patients with poor functional recovery, tendon transfers may be indicated. The decision to perform an early tendon transfer at the time of nerve repair or before expected reinnervation is considered on a case-by-case basis. There are a multitude of potential tendon transfer options, the choices of which depend on remaining function, specific deficits, and surgeon experience and preferences. A thoughtful approach to reconstruction can lead to a substantial functional improvement with minimal donor site morbidity.

The number of women in medicine has grown rapidly in recent years. Women constitute over 50% of medical school graduates and hold 38% of faculty positions at United States medical schools. Despite this, gender disparities remain prevalent in most surgical subspecialties, including plastic surgery. The purpose of this study was to analyze gender authorship trends.A cross-sectional study of academic plastic surgeons was performed. Data were collected from departmental websites and online resources. National Institute of Health (NIH) funding was determined using the Research Portfolio Online Reporting Tools database. Number of published articles and h-index were obtained from Scopus (Elsevier Inc, New York, NY). Statistical analysis was performed in SPSS (SPSS Inc, Chicago, IL).A total of 814 plastic surgeons were identified in the United States. Compared to men, women had significantly fewer years in practice (P 0.001), lower academic ranks (P 0.001), and published less (P 0.001). There was no difference in the number of PhD degrees between genders; women with PhDs published less than men with PhDs (P = 0.04). 5.1% of women and 6.9% of men received NIH funding during their career (P = 0.57). There was no gender difference in scholarly output among NIH-funded surgeons. Overall, years in practice, academic rank, chief/program director title, advanced degrees, and NIH funding all positively correlated with academic productivity.This study identifies significant gender disparities in scholarly productivity among plastic surgeons in academia. Future efforts should focus on improving gender equality and eliminating barriers to academic development.

BACKGROUND There is an increased push for plastic surgery units in the United States to become independent departments administered autonomously rather than as divisions of a multispecialty surgery department. The purpose of this research was to determine whether there are any quantifiable differences in the academic performance of departments versus divisions. METHODS Using a list of the plastic surgery units affiliated with the American Council of Academic Plastic Surgeons, unit Web sites were queried for departmental status and to obtain a list of affiliated faculty. Academic productivity was then quantified using the SCOPUS database. National Institutes of Health funding was determined through the Research Portfolio Online Reporting Tools database. RESULTS Plastic surgery departments were comparable to divisions in academic productivity, evidenced by a similar number of publications per faculty (38.9 versus 38.7; p = 0.94), number of citations per faculty (692 versus 761; p = 0.64), H-indices (9.9 versus 9.9; p = 0.99), and National Institutes of Health grants (3.25 versus 2.84; p = 0.80), including RO1 grants (1.33 versus 0.84; p = 0.53). There was a trend for departments to have a more equitable male-to-female ratio (2.8 versus 4.1; p = 0.06), and departments trained a greater number of integrated plastic surgery residents (9.0 versus 5.28; p = 0.03). CONCLUSION This study demonstrates that the academic performance of independent plastic surgery departments is generally similar to divisions, but with nuanced distinctions.

Retinal image stability is essential for vision but may be degraded by head movements. The vestibulo-ocular reflex (VOR) compensates for passive perturbations of head position and is usually assumed to be the major neural mechanism for ocular stability. During our recent investigation of vestibular reflexes in guinea pigs free to move their heads (Shanidze et al. in Exp Brain Res, 2010), we observed compensatory eye movements that could not have been initiated either by vestibular or neck proprioceptive reflexes because they occurred with zero or negative latency with respect to head movement. These movements always occurred in association with self-generated (active) head or body movements and thus anticipated a voluntary movement. We found the anticipatory responses to differ from those produced by the VOR in two significant ways. First, anticipatory responses are characterized by temporal synchrony with voluntary head movements (latency approximately 1 versus approximately 7 ms for the VOR). Second, the anticipatory responses have higher gains (0.80 vs. 0.46 for the VOR) and thus more effectively stabilize the retinal image during voluntary head movements. We suggest that anticipatory responses act synergistically with the VOR to stabilize retinal images. Furthermore, they are independent of actual vestibular sensation since they occur in guinea pigs with complete peripheral vestibular lesions. Conceptually, anticipatory responses could be produced by a feed-forward neural controller that transforms efferent motor commands for head movement into estimates of the sensory consequences of those movements.
