ABSTRACT

PURPOSE: To systematically review the literature regarding the biomechanical properties of different repair techniques and fixation methods for vertically oriented meniscal tears. METHODS: Human cadaveric studies evaluating the biomechanical properties of different repair techniques for vertically oriented meniscal tears were identified using the PubMed, EMBASE, and Cumulative Index to Nursing & Allied Health databases. Primary outcomes included load to failure, displacement, stiffness, peak contact pressure, and contact area of repaired menisci. Repair techniques from included studies were reclassified into a total of 19 distinct all-inside (AI), inside-out (IO), or outside-in (OI) techniques. RESULTS: Sixteen studies were included (420 total menisci). Contact pressure and area were restored to intact-state values across all 5 compressive load studies at low knee flexion angles but not at greater knee flexion angles (i.e., >60°). There were no significant differences in contact pressure or area between AI, IO, and OI techniques across all studies. Some studies demonstrated statistically significant advantages in tensile properties with IO techniques when compared with AI techniques, whereas others found AI techniques to be superior. No studies directly compared tensile properties of OI techniques with those of AI or IO techniques. Vertical mattress suture configurations resulted in significantly greater load to failure and decreased displacement compared with horizontal mattress configurations in 67% of studies comparing the 2 techniques. There was no difference in the rate of tissue failure in AI (66.97%), IO (60.38%), or OI (66.67%, χ2 = 0.83, P = .66) techniques. CONCLUSIONS: Contact mechanics are reliably restored after repair of vertical meniscal tears at low flexion angles but inconsistently restored at greater flexion angles, regardless of technique. Vertical mattress configurations outperformed horizontal mattress configurations under tensile load. There are conflicting data regarding the comparison of tensile properties between AI and IO techniques. Ultimately, neither AI, IO, nor OI repair demonstrated superior biomechanical properties in the present literature. CLINICAL RELEVANCE: Several repair techniques demonstrate favorable biomechanical properties for vertical meniscal tears under tensile and compressive loads. Neither AI, IO, nor OI repair techniques demonstrate superior biomechanical properties at this time.

ABSTRACT

Background: Surfing is an increasingly popular sport with a high propensity for both traumatic and atraumatic injuries. Purpose: To analyze the trends, etiologies, and diagnoses of lower extremity orthopaedic-related surfing injuries presenting to United States (US) emergency departments (EDs) within a 21-year study period. Study Design: Descriptive epidemiology study. Methods: The National Electronic Injury Surveillance System database was queried for data on lower extremity surfing injuries presenting to US EDs from January 1 to December 31, 2022. Data collected included year, injury mechanism, injury location, diagnosis, and disposition. The raw data were used to calculate national estimates (NEs) based on each hospital's assigned statistical sample weight. Linear regressions were performed to analyze annual trends. Results: A total of 776 lower extremity surfing injuries were included (NE = 49,218 injuries). The mean age of the patients was 29.4 ± 13.6 years. The most common injured areas were the foot (NE = 17,411; 35.4%), lower leg (NE = 8673, 17.6%), and knee (NE = 8139; 16.5%). The most common mechanism of injury was impact with board (NE = 17,144; 34.8%), and the most common fracture locations were the lower leg (NE = 1195; 29.5%), ankle (NE = 1594; 24.5%), and foot (NE = 1495; 23.0%). There were statistically significant decreases in weighted estimates for lower extremity surfing injuries by 108 per year (P < .001), for lacerations by 76 per year (P < .001), and for sprains by 18 per year (P = .01). Impact-with-board injuries decreased by 59 injuries per year (P < .001) and constituted 63.5% of lacerations and 12.1% of fractures. Only 3.9% of patients were admitted for hospitalization. Conclusion: There was a decreasing trend in lower extremity surfing injuries presenting to US EDs during the 21-year study period.

ABSTRACT

Surfing is a globally popular recreational sport with limited epidemiologic data. Currently, there is a paucity of literature regarding injury profiles and mechanisms of orthopaedic-related injuries. This study analyzed trends, etiologies, and diagnoses of upper extremity orthopaedic-related surfing injuries presenting to United States (US) emergency departments. The National Electronic Injury Surveillance System database was accessed to query upper extremity surfing-related injuries presenting to US emergency departments from January 1, 2002 to December 31, 2021. Data were analyzed for year, body part, mechanism of injury, diagnosis, and disposition. National estimates were calculated based on the assigned statistical sample weight of each hospital. A total of 33 323 surfing-related injuries were included. The most common upper extremity body parts involved 15 169 shoulders (45.5%), 4220 fingers (12.7%), and 3753 hands (11.3%). The most common identifiable mechanisms of injuries were 7474 board-to-body (22.4%), 4188 impact with sand (12.6%), and 2639 impact with water (7.9%). Overuse constituted 7.2% of overall upper extremity injuries but 40% of strains. Only 2.2% of injuries required hospital admission. Between 2002 and 2021, there was a decreasing annual trend in upper extremity surfing-related injuries (P=.01). The decreasing trend in emergency department visits may be due to urgent care utilization and training for surfers and lifeguards to manage these injuries on-site, as the majority were minor given the small proportion requiring hospital admission. Chronic stress on rotator cuff and peri-scapular musculature while paddling in the prone position likely contributed to the large proportion of overuse injury.

ABSTRACT

Background: Increased posterior tibial slope (PTS) is a risk factor for knee pathology. Accurate measurement of PTS is predicated on a quality lateral knee radiograph; however, little is known about how the quality of the radiograph affects the measured PTS. Purposes: To (1) describe a method for measuring malalignment on lateral knee radiographs, (2) assess the effects of malpositioning of the knee on radiographic measures of malalignment, and (3) determine any correlations between malalignment and the measured PTS. Study Design: Descriptive laboratory study. Methods: Using a setup similar to that of a standard radiology suite, 25 sets of radiographs were taken using 5 sawbone models. Each set included a true lateral view and separate malpositioned radiographs at 5°, 10°, and 15° of adduction, abduction, internal rotation, and external rotation. Malalignment for each radiograph was quantified as the anterior-posterior distance (APD) and proximal-distal distance (PDD) between femoral condyles. The medial PTS was measured in duplicate, and the interrater reliability was calculated. Results: The interrater reliability was excellent, with intraclass correlation coefficients of 0.92, 0.91, and 0.96 for the APD, PDD, and PTS, respectively. Malrotation significantly affected the APD (P < .001), with a mean change of 5.6 mm per 5°. Malpositioning in abduction/adduction significantly affected the PDD (P < .001), with a mean change of 5.1 mm per 5°. There was no significant impact of rotation or APD on the PTS. Abduction/adduction did affect the PTS (P < .001) above a threshold of 5° of malpositioning. The PTS decreased as the PDD increased, moving from adduction to abduction (R2 = 0.5687). Conclusion: The measured PTS was more sensitive to malpositioning by abduction/adduction than by malrotation. Malrotation affected the APD, while abduction/adduction affected the PDD. Thus, the accuracy of the measured PTS was compromised more by poorly aligned distal femoral condyles than it was by poorly aligned posterior femoral condyles. Clinical Relevance: To minimize the effects of malpositioning, we recommend utilizing radiographs with a |PDD| of <5 mm and an |APD| of <15 mm when measuring the PTS.

ABSTRACT

BACKGROUND: This study directly compares the recurrence rates of dorsal wrist ganglion cysts in patients treated via open surgical excision versus arthroscopic surgical excision. We hypothesized that there would be no difference between recurrence rates with these 2 surgical options. METHODS: We retrospectively reviewed the charts of all patients with a dorsal ganglion cyst undergoing either open or arthroscopic surgical excision at a single academic center with 3 fellowship-trained attending hand surgeons from 2012 to 2017. Charts were identified using Current Procedural Terminology codes and were reviewed using postoperative office notes for preoperative and postoperative symptoms, episodes of recurrence, time at which recurrence occurred, subsequent operations, and outcome at final follow-up. RESULTS: The charts of 172 patients undergoing either arthroscopic or open dorsal ganglion excision were reviewed. Nine of 54 (16.7%) arthroscopic excisions resulted in cyst recurrence, while 8 of 118 (6.8%) open excisions resulted in cyst recurrence (P = .044). Two of 9 (22%) recurrences after arthroscopic ganglion excision versus 2 of 8 (25%) recurrences after open ganglion excision underwent repeat surgical intervention. Time to recurrence, as well as final follow-up, was not statistically different between groups. CONCLUSIONS: Dorsal wrist ganglion cysts are the most common benign soft tissue mass of the upper extremity, but it remains unknown whether arthroscopic or open surgical excision leads to lower recurrence rate. Scant literature exists directly comparing these 2 methods of surgical excision. This study suggests that open excision of dorsal wrist ganglia leads to a lower recurrence rate than does arthroscopic excision.

ABSTRACT

BACKGROUND: There are multiple techniques that attempt to maintain anatomic length-tension relationship during biceps tenodesis. However, no direct comparison has been performed with respect to the timing of biceps tenotomy during biceps tenodesis. This study aims to assess the incidence of Popeye deformity and clinical outcomes of 2 all-arthroscopic techniques for biceps tenodesis based on timing of the biceps tenotomy. METHODS: A consecutive series of patients undergoing arthroscopic biceps tenodesis with concomitant rotator cuff tears were enrolled from 2019 to 2021. Biceps tenodesis performed after tenotomy formed the first cohort (group 1). The other cohort had biceps tenodesis performed prior to biceps tenotomy (group 2). Postoperative anterior arm pain, biceps muscle spasms, and patient perceptions of the appearance of the bicep muscle were assessed. In addition, patient-reported outcomes (PROs) were collected at 3 months and minimum 6 months postoperatively. RESULTS: A total of 71 patients were eligible for participation and 62 patients (53% female, age 58.7 ± 9.0 years) were enrolled (n = 33 in group 1, and n = 29 in group 2). There were no differences between groups with respect to gender, age, and laterality of biceps tenodesis, as well as type and size of rotator cuff repair. At 3-month follow-up, Veterans RAND 12-Item Health Survey (VR-12) physical health summary scores were significantly improved in group 2 (44.8 ± 9.7) compared with group 1 (34.1 ± 3.4) (P = .03). In addition, patients in group 2 experienced significantly less pain in their anterior arm than patients in group 1 (19% vs. 33%, P = .02). There were no differences in biceps muscle spasm (3.4% vs. 5.2%, P = .21) and no other differences in PROs between groups. Final follow-up averaged 11.6 ± 3.3 months in group 1 and 11.8 ± 5.5 months in group 2. There were no significant differences in patient-perceived biceps Popeye deformity between group 1 (12.1%) and group 2 (0%) (P = .652). Furthermore, there were no differences in American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, EuroQol-5 Dimension, Patient-Reported Outcomes Measurement Information System Global Health (PROMIS 10) physical health, PROMIS 10 depression, VR-12 physical health summary, and Single Assessment Numeric Evaluation scores between the 2 technique groups. CONCLUSION: Patients with tenotomy performed after tenodesis had better VR-12 physical health summary scores and less arm pain than patients with tenotomy performed before tenodesis at 3-month follow-up. However, there were no differences in any outcome at final follow-up of nearly 1-year. In addition, there were no differences in perceived Popeye deformity between groups at any time period.

ABSTRACT

Purpose: To evaluate the mid-term rate of revision arthroscopic rotator cuff repair as well as ipsilateral shoulder reoperations after index rotator cuff repair performed with or without acromioplasty in the United States. Methods: The Medicare Standard Analytic File, which encompasses the entire Medicare billing and payment data, was queried between 2005 and 2014. Patients undergoing arthroscopic rotator cuff repair were identified and stratified based on whether ipsilateral acromioplasty was concurrently performed using Current Procedural Terminology codes. Groups were matched by age, sex, year of index procedure, and Elixhauser index at a 2:1 ratio. Primary end point was defined as undergoing a repeat ipsilateral shoulder surgery related to the rotator cuff at 5 years of follow-up. Kaplan-Meier survival curves were constructed, and the 2 groups were compared using the log-rank test. Results: After matching, 54,209 shoulders in the rotator cuff repair with acromioplasty group and 26,448 shoulders in the rotator cuff repair without acromioplasty group were identified. Shoulders undergoing concurrent acromioplasty at index rotator cuff repair had a significantly increased rate of repeat ipsilateral cuff repair at 5 years postoperatively (8.5% vs 6.8%, P < .001). Similarly, there was an increased rate of reoperation of all types to the ipsilateral shoulder in cases where concurrent acromioplasty was performed (9.6% vs 9.1%, P < .001). Conclusions: Using a large, national database, concurrent acromioplasty at the time of rotator cuff tear was found to be associated with both an increase rate of overall subsequent procedures and revision rotator cuff repair. Level of Evidence: III, retrospective comparative study.

ABSTRACT

Purpose: To identify and analyze the 50 most-cited articles in patellar tendon injury research. Methods: The ISI Web of Science and SCOPUS databases were used to conduct a search for articles pertaining to patellar tendon injury. For the top 50 most-cited articles, bibliometric data (title, first and senior author, citation count, journal, publication year, citation density, country of origin, Level of Evidence [LOE]) and topic of article were recorded. Results: The mean number of citations was 172.0 ± 88.2 (range 101-546). There was a statistically significant correlation between publication year and citation density (r = 0.61, P < .01). The earliest article was the third most-cited article (362 citations), published by Blazina et al. in 1973, which discussed the epidemiology of patellar tendinopathy. The first and second most-cited articles (546 and 466 citations, respectively) covered surgical outcomes of patellar tendinopathy and prevalence of patellar tendinopathy among elite athletes. A total of 14 articles (28%) discussed nonoperative management, whereas only 5 articles discussed surgical management (10%). The most frequent LOE category was a LOE of IV (n = 18, 36%), but 19 studies (38%) were LOE I or LOE II. Conclusions: Among the top 50 most-cited studies regarding patellar tendon injury, a relatively high number were of a high LOE (19 Level I or II, 38%), affirming that these articles in patellar tendon injury research are not only influential, but also of high-quality evidence. Clinical Relevance: This bibliometric analysis provides an efficient tool for educators, researchers, and evidence-based practitioners to identify and evaluate the most influential articles in patellar tendon injury research.

ABSTRACT

How do relationships among newcomers in the same cohort impact how quickly they develop clear understandings of their new roles and, ultimately, key socialization outcomes? We study newcomers' relationships with cohort members in the same unit (i.e., intra-unit relationships) and those in different units (i.e., inter-unit relationships). While organizations invest substantial time and resources in promoting broad networking among newcomers, we offer a theoretical and empirical account of how too many connections among fellow newcomers early in the socialization process can slow their adjustment-namely, their growth in role clarity. In Study 1, we surveyed 189 newcomers in an international conglomerate from their orientations through their first 4 months and linked responses to 3 years of their job performance and turnover records. After controlling for the initial level of role clarity, we found an inverted U-shaped relationship between newcomers' intra-unit peer connections and growth in role clarity, whereas their inter-unit peer connections did not significantly relate to growth in role clarity. Growth in role clarity positively related to subsequent newcomers' job satisfaction and job performance, which were then negatively related to turnover. Study 2's results indicated that sensemaking with fellow newcomers operated as a key mechanism linking the nonlinear relationships between intra-unit newcomer-newcomer relationships and growth in role clarity.

ABSTRACT

BACKGROUND: Injury to the ulnar collateral ligament of the elbow is common among overhead throwing athletes and can result in significant functional limitations. While surgical reconstruction offers high rates of return to competition, there are no validated or universally accepted guidelines for determining when an athlete can safely resume play. PURPOSE: To assess the existing scientific literature for return-to-competition criteria utilized after ulnar collateral ligament reconstruction. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 4. METHODS: The PubMed database was searched for clinical investigations of ulnar collateral ligament reconstruction in overhead throwing athletes published between January 2000 and June 2020. Only studies that had a minimum follow-up of 1 year and included at least 1 specific return-to-competition criterion were considered. RESULTS: A total of 15 studies were included in the final analysis, encompassing 1156 patients with an average age of 20.7 years (SD, 2.0 years). Baseball players composed 96.3% of patients for whom sport was specified, and 92.4% of baseball players were pitchers. The most common return-to-competition criterion, identified in 87% of studies, was completion of a return-to-throwing program, which started on average 16.7 weeks (range, 12-18 weeks) after surgery. A return-to-mound program was utilized in 53% of studies, starting on average 7.4 months (range, 6-9 months) postoperatively. Minimum time from surgery was used in 73% studies, with players waiting 7 to 12 months (mean, 9.7; SD, 1.4 months) after surgery before return-to-competition consideration. The overall rate of return to competition at the preinjury level or higher was 85.7% (SD, 8.5%) at an average of 12.2 months (SD, 0.6 months). CONCLUSION: In general, we observed a paucity of literature describing the return-to-competition process after ulnar collateral ligament reconstruction in overhead throwing athletes. Only 3 explicit return-to-competition criteria were identified across all studies: completion of a return-to-throwing program, completion of a return-to-mound program for pitchers, and minimum time from surgery. Increased transparency regarding postoperative rehabilitation protocols and further research are necessary to identify and validate sport-specific return-to-competition criteria, which will ultimately help athletes return to play in a safe and timely fashion after ulnar collateral ligament reconstruction.

ABSTRACT

OBJECTIVES: Neck injuries in football are attributed to helmet-to-helmet contact with youth players being at greatest risk. In 2014, the National Federation of State High School Associations (NFHS) implemented rules defining illegal contact against a defenseless player above the shoulders to reduce head and neck injuries in football players. This study evaluates whether rule implementation decreased rates of high school football neck injuries presenting to the emergency department (ED) pre-rule implementation (2009-2013) to post-rule implementation (2015-2019). METHODS: Data were queried from the National Electronic Injury Surveillance System for high school football players 14 to 18 years old diagnosed with a neck injury from 1 January 2009 to 31 December 2019. Narratives in the data were reviewed for mechanism of injury, setting, loss of consciousness (LOC), and type of injury. RESULTS: Between 2009 and 2019, an estimated 47,577 high school football neck injuries were diagnosed in EDs across the United States. 52.0% of neck injuries were sustained during competition compared to 48.0% during practice. A statistically significant (P = 0.004) decrease in neck injuries was realized from pre-rule implementation to post-rule implementation with averages of 5,278 and 3,481 injuries per year, respectively. Helmet-to-helmet neck injuries significantly (P = 0.04) decreased from pre- to post-rule implementation with averages of 851 and 508 injuries per year, respectively. Neck injuries sustained via other mechanisms were not affected by the 2014 rule implementation. CONCLUSION: This study is the first to identify a decrease in overall and helmet-to-helmet related neck injuries diagnosed in the ED following the 2014 NFHS targeting rule implementation. These findings add to the growing literature regarding the importance and efficacy of rule implementation in reducing sports-related neck injuries.

ABSTRACT

BACKGROUND: Concussions occur at higher rates in high school football as compared with all other high school sports. In 2014, the National Federation of State High School Associations implemented rules defining illegal contact against a defenseless player above the shoulders to reduce concussions in football players in the United States. To the best of our knowledge, rates of emergency department (ED)-diagnosed concussions of high school football players before and after the 2014 rule implementation have not been compared. HYPOTHESIS: It was hypothesized that (1) there would be lower rates of helmet-to-helmet and helmet-to-body-part concussions after rule implementation and (2) alternative mechanisms of concussion would not differ, as these would be less influenced by rule implementation. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Data from the National Electronic Injury Surveillance System (NEISS) were analyzed for high school football players 14 to 18 years old sustaining a concussion from January 1, 2009, to December 31, 2019. Data were collected on mechanism of injury, setting, and loss of consciousness. Raw data were used to calculate national estimates based on the assigned statistical sample weight of each hospital by the NEISS. RESULTS: A total of 4983 (national estimate = 154,221) high school football concussions were diagnosed in US EDs; 58.8% of concussions occurred during competition and 41.2% during practice. Between 2009 and 2013 the rate of concussions diagnosed in EDs rose 10.7% as compared with a 6.2% decrease between 2015 and 2019 (P = .04). Between 2009 and 2013, the rate of helmet-to-helmet concussions rose 17.6% as compared with a 5.6% decrease between 2015 and 2019 (P = .03). There were no significant changes between other mechanisms of concussion before and after the 2014 rule implementation. CONCLUSION: We identified a decreased trend in overall and helmet-to-helmet high school football concussions diagnosed in the ED after implementation of the targeting rule. This study adds to the growing literature regarding the importance and efficacy of rule implementation in reducing sports-related concussions.

ABSTRACT

Meloidogyne enterolobii (syn. mayaguensis) is an emergent species of root-knot nematode that has become a serious threat to sweet potato (Ipomoea batatas) production in the southeastern United States. The most popular sweet potato cultivars grown in this region are highly susceptible to M. enterolobii. As a result, this pest has spread across most of the sweet potato growing counties in the Carolinas, threatening the industry as well as other crops in the region. The development and release of new sweet potato cultivars with resistance to M. enterolobii would help to manage and slow the spread of this pest. To support sweet potato resistance breeding efforts, 93 accessions selected from the U.S. Department of Agriculture germplasm collection and breeding programs in the United States were screened to identify 19 lines with strong resistance to M. enterolobii. The resistance in these accessions was tested against two M. enterolobii isolates that were collected from sweet potato production fields in the Carolinas. These isolates were found to have distinct pathotypes, with galling and nematode reproduction differences observed on cotton as well as sweet potato. This study is the first report of intraspecific pathotypic variation in M. enterolobii, and it identifies sweet potato germplasm with resistance against both pathogenic variants of this nematode.

ABSTRACT

Job search is an important activity that people engage in during various phases across the life span (e.g., school-to-work transition, job loss, job change, career transition). Based on our definition of job search as a goal-directed, motivational, and self-regulatory process, we present a framework to organize the multitude of variables examined in the literature on job seeking and employment success. We conducted a quantitative synthesis of the literature to test relationships between job-search self-regulation, job-search behavior, and employment success outcomes. We also quantitatively review key antecedents (i.e., personality, attitudinal factors, and contextual variables) of job-search self-regulation, job-search behavior, and employment success. We included studies that examined relationships with job-search or employment success variables among job seekers (e.g., new labor market entrants, unemployed individuals, employed individuals), resulting in 378 independent samples (N = 165,933). Most samples (74.3%, k = 281) came from articles published in 2001 or later. Findings from our meta-analyses support the role of job-search intensity in predicting quantitative employment success outcomes (i.e., rc = .23 for number of interviews, rc = .14 for number of job offers, and rc = .19 for employment status). Overall job-search intensity failed to predict employment quality. Our findings identify job-search self-regulation and job-search quality as promising constructs for future research, as these predicted both quantitative employment success outcomes and employment quality. Based on the results of the theoretical and quantitative synthesis, we map out an agenda for future research. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

ABSTRACT

BACKGROUND: Total shoulder arthroplasty (TSA) is an increasingly common procedure. This study looked at trends in TSA using a nationwide registry, with a focus on patient demographics, comorbidities, and complications. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent TSA from 2005 to 2018. Cohorts were created based on year of surgery: 2005-2010 (N = 1116), 2011-2014 (N = 5920), and 2015-2018 (N = 16,717). Patient demographics, comorbidities, operative time, hospital length of stay, discharge location, and complications within 30 days of surgery were compared between cohorts using bivariate and multivariate analysis. RESULTS: Bivariate analysis revealed significantly more comorbidities among patients in the 2015-2018 cohort compared with the 2005-2010 cohort, specifically American Society of Anesthesiologist class III or IV (57.0% vs. 44.3%, P < .001), morbid obesity (10.8% vs. 7.8%, P < .001), diabetes (17.8% vs. 12.1%, P < .001), and chronic obstructive pulmonary disease (6.7% vs. 4.1%, P = .003). The use of regional anesthesia has decreased (5.6% in 2005-2010 vs. 2.8% in 2015-2018, P < .001), as has operative time (▵: -16 minutes, P < .001) and length of stay (▵: -0.6 days, P < .001). There were also significant decreased rates of perioperative blood transfusion (OR [odds ratio], 0.46), non-home discharge (OR, 0.79), urinary tract infection (OR, 0.47), and sepsis (OR, 0.17), (P < .001 for all comparisons) between the 2005-2010 and 2015-2018 cohorts. CONCLUSIONS: Between 2005 and 2018, patients undergoing TSA had increasingly more comorbidities but experienced lower rates of short-term complications, in the context of shorter hospitalizations and more frequent discharge to home.

ABSTRACT

The preponderance of organizational socialization research has focused on the perceptions and interests of newcomers. Yet, insiders-particularly immediate supervisors-are central to newcomers' adjustment, primarily in providing newcomers help. To facilitate such behavior, however, it is necessary to understand supervisors' helping motivations. Beginning from a new theoretically grounded taxonomy, we examined how supervisor reports of their own self-oriented, other-oriented, and normative motives predicted newcomer-rated received help and subsequent adjustment/socialization outcomes. We also examined the moderating role of newcomer motive perceptions on whether help was reciprocated to supervisors. Our model was tested with multiwave data from newcomers and supervisors during the first 3 months of starting a job. Newcomers reported receiving greater help from supervisors who described themselves as being motivated by self-oriented tangible gains and other-orientation, whereas supervisors who described themselves as being motivated by self-oriented enhancement were seen as less helpful. Further, when newcomers perceived that supervisors were more motivated by other-orientation and less by self-oriented tangible gains, newcomers reciprocated more help to the supervisor later on. Our results advance theory about the role of interpersonal helping during socialization, revealing that not all provided help is interpreted similarly by newcomers, and that differing supervisor motivations should also be factored into account.

ABSTRACT

INTRODUCTION: The purpose of this study was to describe four cases of patients who developed concomitant upper extremity and gluteal compartment syndrome in the context of substance abuse. In somnolent patients unable to provide a reliable physical exam, the healthcare provider must be aware of patients presenting with concomitant upper extremity and gluteal compartment syndrome. METHODS: Retrospective chart review identified cases of the combined upper extremity and gluteal compartment syndrome following illicit drug abuse at a single academic center during the years 2009-2019. RESULTS: During the 11-year period examined, a total of eight patients were diagnosed with compartment syndrome secondary to illicit drug use and prolonged immobilization. Four (50%) patients presented with combined upper extremity and gluteal compartment syndrome. All of these patients underwent prompt surgical release of the affected compartments. All eventually returned to normal activities of daily living. DISCUSSION: Compartment syndrome is primarily a clinical diagnosis, with physical exam being extremely important. In patients presenting with somnolence secondary to illicit drug use, physical exam may not be reliable. It is critical to have a high clinical suspicion in this patient population, understanding that these patients may present with concomitant upper extremity and gluteal compartment syndrome. LEVEL OF EVIDENCE: Level IV, case series.

ABSTRACT

STUDY DESIGN: Retrospective cohort. OBJECTIVES: Identify the effectiveness of vertebral body stapling (VBS) in children with idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: VBS has been proposed as an alternative to bracing moderate curves in patients with adolescent idiopathic scoliosis (AIS) although a clear picture of comparative efficacy and safety remains to be established. METHODS: Ten skeletally immature patients with AIS and curves between 25° and 35° underwent anterior VBS by a single surgeon from 2008 to 2018. Indications included strong family history, high ScoliScore, curve progression despite bracing, or as an alternative for patients/families refusing bracing. Patients with thoracic kyphosis greater than 40°, curvature with a level above T4 or below L4, and double major curves were contraindicated. Patients with hybrid surgical plans or those who failed to reach skeletal maturity were excluded. Age, gender, levels stapled, pre- and postoperative radiographs, and incidence of secondary surgical intervention were evaluated. Outcomes were also compared with untreated and braced subjects from the BrAIST study. RESULTS: Ten patients met the inclusion criteria. Average age at VBS was 11.8 (9.7-13.5) with an average major Cobb angle of 30.9° (26°-35°). Average duration of follow-up was 6.4 years. All patients demonstrated curve correction at their first postoperative visit. At final follow-up, 50% of patients experienced curve progression greater than 5°, whereas the remaining 50% either remained stable or corrected over time. The five patients whose curves progressed underwent VBS at a significantly younger age (10.8 vs. 12.8; p value .003). Four of these patients required additional surgical intervention for worsening scoliosis. CONCLUSIONS: Although early outcomes after VBS appear to parallel the results of bracing, stapling does not affect the percentage of patients ultimately requiring PSIF. Initial curve correction degraded over time in younger patients with significant growth remaining, and high rates of progression in this group, even with bracing, merits investigation into more efficacious treatment strategies. LEVEL OF EVIDENCE: Level III.

ABSTRACT

How and to what extent does extraversion relate to work relevant variables across the lifespan? In the most extensive quantitative review to date, we summarize results from 97 published meta-analyses reporting relations of extraversion to 165 distinct work relevant variables, as well as relations of extraversion's lower order traits to 58 variables. We first update all effects using a common set of statistical corrections and, when possible, combine independent estimates using second-order meta-analysis (Schmidt & Oh, 2013). We then organize effects within a framework of four career domains-education, job application, on the job, and career/lifespan-and five conceptual categories: motivations, values, and interests; attitudes and well-being; interpersonal; performance; and counterproductivity. Overall, extraversion shows effects in a desirable direction for 90% of variables (grand mean ρ̄ = .14), indicative of a small, persistent advantage at work. Findings also show areas with more substantial effects (ρ̄ ≥ .20), which we synthesize into four extraversion advantages. These motivational, emotional, interpersonal, and performance advantages offer a concise account of extraversion's relations and a new lens for understanding its effects at work. Our review of the lower order trait evidence reveals diverse relations (e.g., the positive emotions facet has consistently advantageous effects, the sociability facet confers few benefits, the sensation-seeking facet is largely disadvantageous), and extends knowledge about the functioning of extraversion and its advantages. We conclude by discussing potential boundary conditions of findings, contributions and limitations of our review, and new research directions for extraversion at work.

ABSTRACT

Work history information reflected in resumes and job application forms is commonly used to screen job applicants; however, there is little consensus as to how to systematically translate information about one's work-related past into predictors of future work outcomes. In this article, we apply machine learning techniques to job application form data (including previous job descriptions and stated reasons for changing jobs) to develop interpretable measures of work experience relevance, tenure history, and history of involuntary turnover, history of avoiding bad jobs, and history of approaching better jobs. We empirically examine our model on a longitudinal sample of 16,071 applicants for public school teaching positions, and predict subsequent work outcomes including student evaluations, expert observations of performance, value-added to student test scores, voluntary turnover, and involuntary turnover. We found that work experience relevance and a history of approaching better jobs were linked to positive work outcomes, whereas a history of avoiding bad jobs was associated with negative outcomes. We also quantify the extent to which our model can improve the quality of selection process above the conventional methods of assessing work history, while lowering the risk of adverse impact.
