Review
The proximal humeral fracture (PHF) is one of the most common fractures in elderly patients. A PHF might influence the quality of life (QoL) on several different levels, especially in elderly patients, but it is unclear which treatment option results in a better QoL outcome. Therefore, we aimed to systematically review the current literature for studies that have analyzed the QoL and pain of elderly patients treated either surgically or non-operatively for PHF. A comprehensive search of the literature was performed in the PubMed database from January to April 2023. Studies describing the QoL or the level of pain of patients older than 60 years with the EuroQoL-5 Dimension (EQ-5D) score or the visual analogue scale (VAS) after the treatment of PHF, either non-operatively (non-OP), with open-reduction and internal fixation using a locking plate (LPF), or with reverse total shoulder arthroplasty (RTSA) were included. Twelve studies were analyzed descriptively and the individual risk of bias was assessed using the ROB2 and ROBINS-I tools. A total of 12 studies with 712 patients at baseline were included (78% female sex, mean age 75.2 years). The reported VAS scores at 12-month follow-up (FU) ranged from 0.7 to 2.5. The calculated overall mean VAS score across all studies showed a decreasing tendency for all treatments, with an increasing FU time up to 12 months after PHF. None of the studies reported any significant differences of the EQ-5D across the groups. The overall calculated EQ-5D indices showed an increasing trend after 6-8 weeks FU, but did not differ significantly between the three treatments. In conclusion, the current literature suggests that there are no clinically important differences between the QoL or pain in elderly patients with PHF after non-operative treatment or surgical treatment with LPF or RTSA. However, the number of studies and level of evidence is rather low and further trials are urgently needed.

Spine Deformity Nov 2022To assess surgical and safety outcomes associated with different rod materials and diameters in adolescent idiopathic scoliosis (AIS) surgery. (Meta-Analysis)
Meta-Analysis Review
PURPOSE
To assess surgical and safety outcomes associated with different rod materials and diameters in adolescent idiopathic scoliosis (AIS) surgery.
METHODS
A systematic literature review and meta-analysis evaluated the surgical management of AIS patients using pedicle screw fixation systems (i.e., posterior rods and pedicle screws) with rods of different materials and sizes. Postoperative surgical outcomes (e.g., kyphosis and coronal correction) and complications (i.e., hyper/hypo-lumbar lordosis, proximal junctional kyphosis, revisions, reoperations, and infections) were assessed. Random-effects models (REMs) pooled data for outcomes reported in ≥ 2 studies.
RESULTS
Among 75 studies evaluating AIS surgery using pedicle screw fixation systems, 46 described rod materials and/or diameters. Two studies directly comparing titanium (Ti) and cobalt-chromium (CoCr) rods found that CoCr rods provided significantly better postoperative kyphosis angle correction vs. Ti rods during a shorter follow-up (0-3 months, MD = - 2.98°, 95% CI - 5.79 to - 0.17°, p = 0.04), and longer follow-up (≥ 24 months, MD = - 3.99°, 95% CI - 6.98 to - 1.00, p = 0.009). Surgical infection varied from 2% (95% CI 1.0-3.0%) for 5.5 mm rods to 4% (95% CI 2.0-7.0%) for 6 mm rods. Reoperation rates were lower with 5.5 mm rods 1% (95% CI 0.0-3.0%) vs. 6 mm rods [6% (95% CI 2.0-9.0%); p = 0.04]. Differences in coronal angle, lumbar lordosis, proximal junctional kyphosis, revisions, and infections did not differ significantly (p > 0.05) among rods of different materials or diameters.
CONCLUSION
For AIS, CoCr rods provided better correction of thoracic kyphosis compared to Ti rods. Patients with 5.5 mm rods had fewer reoperations vs. 6.0 and 6.35 mm diameter rods.

Review
PURPOSE
Minimally displaced pediatric proximal humerus fractures can be reliably managed non-operatively; however, there is considerable debate regarding the appropriate management of severely displaced proximal humerus fractures, particularly in older children and adolescents with limited remodeling potential. The purpose of this study was to perform a systematic review to answer the questions: "What are the functional and quality-of-life outcomes of pediatric proximal humerus fractures?" and "What factors have been associated with a poorer outcome?"
METHODS
A review of Medline and Embase was performed on 4 July 2021 using search terms relevant to proximal humerus fractures, surgery, non-operative management, pediatrics, and outcomes. Studies including ≥10 pediatric patients with proximal humerus fractures, which assessed clinical outcomes by use of an established outcome measure, were selected. The following clinical information was collected: participant characteristics, treatment, complications, and outcomes.
RESULTS
Twelve articles were selected, including four prospective cohort studies and eight retrospective cohort studies. Favorable outcome scores were found for patients with minimally displaced fractures, and for children aged less than 10 years, irrespective of treatment methodology or grade of fracture displacement. Older age at injury and higher grade of fracture displacement were reported as risk factors for a poorer patient-reported outcome score.
CONCLUSION
An excellent functional outcome can be expected following non-operative management for minimally displaced pediatric proximal humerus fractures. Prospective trials are required to establish a guideline for the management of severely displaced proximal humerus fractures in children and adolescents according to fracture displacement and the degree of skeletal maturity.

Review
BACKGROUND
Patient-reported outcome measures are important to determine outcomes after orthopaedic procedures. There is currently no standard for outcome measures in the evaluation of patient outcomes after proximal hamstring repair.
PURPOSE
To identify and evaluate outcome measures used after proximal hamstring repair.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
A systematic review was performed to identify all English-language articles assessing outcomes after proximal hamstring repair in PubMed, Embase, CINAHL via EBSCOhost, MEDLINE via OvidSP, and Web of Science between 2000 and 2019. After duplicates were removed, studies were selected using eligibility criteria established by the authors. Image reviews, anatomic/histology studies, literature reviews, surgical technique reports, systematic reviews, narrative reviews, case studies, and studies with <5 patients were excluded. Extraction, synthesis, and analysis of outcome measure data were performed using Microsoft Excel. Quality assessment of included studies was performed using Methodological Index for Non-Randomized Studies criteria.
RESULTS
After duplicate articles were removed, a total of 304 unique articles were identified and 27 met the inclusion criteria. The mean number of patients with proximal hamstring repairs per study was 40. The most frequently reported outcome measures were return to sport (14/27; 51.9%), custom survey/questionnaire (13/27; 48.1%), and isokinetic hamstring strength testing (13/27; 48.1%). Six of the 10 most commonly used outcome measures were validated and included Lower Extremity Functional Scale, 12-Item Short Form Health Survey, visual analog scale for pain, Perth Hamstring Assessment Tool (PHAT), Single Assessment Numeric Evaluation, and Tegner Activity Scale. Of those, PHAT was the only validated outcome measure designed for proximal hamstring repair.
CONCLUSION
There is currently no consensus on the best outcome measurements for the evaluation of patients after proximal hamstring repair. We recommend an increased commitment to the use of return to sport, isokinetic strength testing, Lower Extremity Functional Scale, and PHAT when assessing such injuries. Future studies should aim to define the most reliable methods of outcome measurement in this patient population through consistent use of tools that are clinically relevant and important to patients and can easily be employed in a variety of clinical scenarios.

Review
Proximal interphalangeal joint (PIPJ) arthrodesis is a salvage option in the management of end-stage PIPJ arthropathy. Numerous techniques have been described, including screws, Kirschner wires, tension band wiring, intramedullary devices, and plate fixation. There remains no consensus as to the optimum method, and no recent summary of the literature exists. A literature search was conducted using the MEDLINE, EMBASE, and PubMed databases. English-language articles reporting PIPJ arthrodesis outcomes were included and presented in a systematic review. Pearson χ and 2-sample proportion tests were used to compare fusion time, nonunion rate, and complication rate between arthrodesis techniques. The mean fusion time ranged from 5.1 to 12.9 weeks. There were no statistically significant differences in fusion time between arthrodesis techniques. Nonunion rates ranged from 0.0% to 33.3%. Screw arthrodesis demonstrated a lower nonunion rate than wire fusion (3.0% and 8.5% respectively; = .01). Complication rates ranged from 0.0% to 22.1%. Aside from nonunions, there were no statistically significant differences in complication rates between arthrodesis techniques. The available PIPJ arthrodesis techniques have similar fusion time, nonunion rate, and complication rate outcomes. The existing data have significant limitations, and further research would be beneficial to elucidate any differences between techniques.

Despite significant scholarly attention and practical importance regarding who emerges as informal and formal leaders in organizations, an integrative framework of the leadership emergence literature remains elusive. The presence of such a framework proves integral for the advancement of work in this area due to the complexity of the field, coupled with its sprawling nature across multiple disciplines (e.g., management, communication, education, economics). Accordingly, in this review, we utilize a database of 270 primary studies to put forth a distal-proximal framework of leadership emergence. In particular, we systematically review past research to answer four questions: (1) what do we know about the phenomenon of leadership emergence itself, (2) what are the antecedents of leadership emergence, (3) what outcomes are associated with leader emergence, and (4) what are the boundary conditions of leadership emergence? By introducing a conceptual framework for informal and formal emergent leadership, we highlight areas of research maturity and nascency and offer several recommendations for future work in this domain. Altogether, we highlight broad theoretical implications for the leadership, teams, and individual differences literature-and elaborate upon several benefits that an integrated framework of emergent leadership provides for organizations.

Review
This systematic review and meta-analysis aimed at assessing the diagnostic accuracy of emerging technologies, such as laser fluorescence (LF), transillumination, light-emitting diode devices, optical coherence tomography (OCT), alternating current impedance spectroscopy, fluorescence cameras (FC), photo-thermal radiometry, and modulated luminescence technology. In vivo and in vitro results of such non-ionizing, non-invasive, and non-destructive methods' effectiveness in non-cavitated dentin caries detection are sometimes ambiguous. Following the PRISMA guidelines, 34 relevant research articles published between 2011-2021 were selected. The risk of bias was assessed with a tool tailored for caries diagnostic studies, and subsequent quantitative uni- and bi-variate meta-analysis was carried out in separate sub-groups according to the investigated surface (occlusal/proximal) and study setting (in vivo/in vitro). In spite of the high heterogeneity across the review groups, in vitro studies on LF and FC proved a good diagnostic ability for the occlusal surface, with area under the curve (AUC) of 0.803 (11 studies) and 0.845 (five studies), respectively. OCT studies reported an outstanding performance with an overall AUC = 0.945 (four studies). Promising technologies, such as OCT or FC VistaProof, still need well-designed and well-powered studies to accrue experimental and clinical data for conclusive medical evidence, especially for the proximal surface.

Meta-Analysis Review
BACKGROUND
The purpose of this study was to perform a systematic review and meta-analysis of both randomized controlled and observational studies comparing conservative to surgical treatment of displaced proximal humerus fractures.
METHODS
We performed a systematic review of Medline, Embase, Scopus, and Google Scholar articles comparing surgical treatment to conservative treatment, including all level 1-3 studies from 2000 to 2022. Clinical outcome scores, range of motion, and complications were evaluated. Risk of bias was assessed using the Cochrane Collaboration's ROB2 tool and ROBINs-I tool. The GRADE system was used to assess the quality of the body of evidence, and heterogeneity was assessed using χ and I statistics. Twenty-two studies were incorporated into the analysis. Ten studies had a high risk of bias, and all included studies were of low quality.
RESULTS
The pooled estimates failed to identify differences for clinical outcomes (P = .208), abduction (P = .275), forward flexion (P = .447), or external rotation (P = .696). Complication rates between groups were significantly lower (P = .00001) in the conservative group.
CONCLUSIONS
This meta-analysis demonstrated that there were no statistically significant differences for either clinical outcomes or range of motion between surgically managed and conservatively treated displaced proximal humerus fractures. The overall complication rate was 3.3 times higher, following surgical treatment. The validity of this result is compromised by the high risk of bias and very low level of certainty of the included studies, and the conclusion must therefore be interpreted with caution.

BACKGROUND
Thoracic endovascular aortic repair, initially intended for thoracic aortic disease treatment, has extended its application to the proximal zone of the aorta. However, the safety and surgical outcomes of extending the proximal landing zone into the ascending aorta (zone 0) in selected cases remain unknown. Thus, we performed a systematic review and meta-analysis of zone 0 thoracic endovascular aortic repair (TEVAR) to obtain a deeper understanding of its safety, outcomes, and trends over time.
METHODS
A literature search was performed using PubMed, EMBASE, and Web of Science databases in accordance with the preferred reporting items for systematic reviews and meta-analyses guidelines, from January, 1997 to January, 2022. Only studies involving zone 0 TEVAR were included. The retrieved data from the eligible studies included basic study characteristics, 30-day/in-hospital mortality rate, indications, comorbidities, stent grafts, techniques, and complications. Summary effect measures of the primary outcomes were obtained by logarithmically pooling the data with an inverse variance-weighted fixed-effects model.
RESULTS
Fifty-three studies with 1,013 patients were eligible for analysis. The pooled 30-day/in-hospital mortality rate of zone 0 TEVAR was 7.49%. The rates of post-operative stroke, type Ia endoleak, retrograde type A aortic dissection, and spinal cord ischemia were 8.95, 9.01, 5.72, and 4.12%, respectively.
CONCLUSIONS
Although many novel stent grafts and techniques targeting zone 0 TEVAR are being investigated, a consensus on technique and device selection in zone 0 TEVAR is yet to be established in current practice. Furthermore, the post-operative stroke rate is relatively high, while other complication rates and perioperative death rate are comparable to those of TEVAR for other aortic zones.

Review
BACKGROUND
Since its approval for use, reverse shoulder arthroplasty (RSA) has become the primary treatment for cuff tear arthropathy, with indications expanding more recently to include revision fracture, osteoarthritis with significant glenoid bone loss, tumor, and chronic instability. Instability is a well-described postoperative complication, occurring in 1to 31% of relatively small cohorts and case series. Given the relative infrequency of instability, there remains a need for a comprehensive review of instability with a focus on risk factors and management. Our goal of this systematic review is to describe the prevalence, risk factors, and management strategies for instability following RSA.
METHODS
A systematic review of the PubMed, EMBASE, MEDLINE, Scopus, and Cochrane Library databases was performed according to PRISMA guidelines. Inclusion criteria included primary RSA cohorts ≥ 100 patients, revision RSA cohorts of any size, and minimum 1-year follow-up. The primary outcome of interest was postoperative instability. MINORS criteria were used to assess study bias. Descriptive statistical analysis was performed with data reported as ranges.
RESULTS
Seventeen studies that included 7885 cases of RSA were reviewed. The mean follow-up ranged from 12 to 84 months. Mean age ranged from 64 to 77 years old, and males represented 19 to 39% of cohorts. There were 204 (2.5%) dislocations in 7885 cases, accounting for a rate of instability from 0.4 to 49% across all studies. By intervention, instability rates ranged from 1 to 5% (primary RSA cases), 1 to 49% (revision RSA cases only), and 0.4 to 10% (mixed cohorts). Subscapularis insufficiency and proximal humerus fractures, and fracture sequelae (malunion and nonunion) were identified as risk factors for instability. Closed reduction and casting and revision RSA were reported as successful treatment strategies with acceptable rates of stable prostheses (28-100% and 55-100%, respectively, across studies). Hemiarthroplasty or resection arthroplasty due to recurrent instability was not uncommon after 2 or more episodes of instability.
CONCLUSION
Instability following RSA occurs infrequently (1-5%) following primary RSA and more commonly following revision RSA (1-49%). RSA for acute proximal humerus fracture and fracture sequelae carries a higher risk of instability. Subscapularis repair appears to be a protective factor. While instability may be successfully treated with closed management or revision RSA, recurrent instability may ultimately require hemiarthroplasty or resection arthroplasty.
