Meta-Analysis Review
OBJECTIVES
This systematic review aimed at evaluating the accuracy of radiographic caries detection for different lesions at different locations.
DATA
Studies reporting on the accuracy (sensitivity/specificity) of radiographic detection of natural primary caries lesions under clinical or in vitro conditions were included. Risk of bias was assessed using QUADAS-2. Pooled sensitivity, specificity and diagnostic odds ratios (DORs) were calculated using random-effects meta-analysis. Analyses were performed separately for occlusal and proximal lesions, with further discrimination between any kind of lesions, dentine lesions, and cavitated lesions.
SOURCES
Electronic databases (Medline, Embase, Cochrane Central) and grey literature were systematically searched, complemented by cross-referencing from bibliographies.
STUDY SELECTION
From 947 identified articles, 442 were analyzed full-text. 117 studies (13,375 teeth, 19,108 surfaces) were included, the majority of them reporting on permanent teeth and having high risk of bias. The detection of any kind (i.e. also initial) lesions had low sensitivities (pooled DOR [95% CI]: 0.24 [0.21/0.26] to 0.42 [0.31/0.34]), but moderate to high specificities (0.70 [0.76/0.84] to 0.97 [0.95/0.98]). For dentine lesions, sensitivities were higher (from 0.36 [0.24/0.49] for proximal to 0.56 [0.53/0.59] for occlusal lesions), and specificities ranged between 0.87 [0.85/0.89] and 0.95 [0.94/0.96]. No studies reported on cavitated occlusal lesions, whilst for cavitated proximal lesions, sensitivities increased above 0.60, whilst sensitivities remained high (above 0.90).
CONCLUSIONS
Radiographic caries detection is highly accurate for cavitated proximal lesions, and seems also suitable to detect dentine caries lesions. For detecting initial lesions, more sensitive methods could be considered in population with high caries risk and prevalence.
CLINICAL SIGNIFICANCE
Radiographic caries detection is especially suitable for detecting more advanced caries lesions, and has limited risks for false positive diagnoses. For groups with high caries risk and prevalence, alternative detection methods with higher sensitivity for initial lesions might be considered.

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
OBJECTIVE
Hypospadias surgery is a humbling art form. Although outcomes with distal hypospadias are favorable, recent publications have suggested that the complication rates are much higher than previously anticipated for proximal hypospadias. The present review examined the literature concerning proximal hypospadias, to explore some of the inadequacies and identify some of the reasons behind these shortfalls in the reported data.
METHODS
A systematic review of the published literature was conducted using keywords relevant to proximal hypospadias and long-term outcomes.
RESULTS
The literature for hypospadias was reviewed, and outcomes for distal vs proximal variants were compared. The quality of the literature for proximal hypospadias was examined, and the shortcomings that led to underreporting of the surgical outcomes were identified. Special focus was on the lack of standardized documentation, the subsequent inability to objectify the severity of the phenotype, and the underestimation of complications due to lack of long-term follow-up. There was also a great deal of variability in the utilized techniques, and the literature was filled with small case series from single institutions. To enable scientific assessment of outcomes, it is proposed that the following be implemented: acceptance and incorporation of standardized phenotype assessment scores in the pre-operative period, objective intraoperative hypospadias characterization, and postoperative score assessment.
CONCLUSIONS
Treatment of proximal hypospadias is much less successful than the distal variant. A specialty wide commitment to standardize the hypospadias language is required to make advancement in surgical outcomes. Boys need to be followed through puberty into adulthood, and honest reporting of outcomes must be discussed so that surgical techniques for this complicated disease process can be advanced.

Review
STUDY DESIGN
Systematic review of literature.
OBJECTIVE
To perform a comprehensive English language systematic literature review of proximal junctional kyphosis (PJK) and proximal junctional failure (PJF), concentrating on incidence, risk factors, health related quality of life impact, prevention strategy, and classification systems.
SUMMARY OF BACKGROUND DATA
PJK and PJF are well described clinical pathologies and are a frequent cause of revision surgery. The development of a PJK classification that correlates with clinical outcomes and guides treatment decisions and possible prevention strategies would be of significant benefit to patients and surgeons.
METHODS
The phrases "proximal junctional," "proximal junctional kyphosis," and "proximal junctional failure" were used as search terms in PubMed for all years up to 2014 to identify all articles that included at least one of these terms.
RESULTS
Fifty-three articles were identified overall. Eighteen articles assessed for risk factors. Eight studies specifically reviewed prevention strategies. There were no randomized prospective studies. There were 3 published studies that have attempted to classify PJK. The reported incidence of PJK ranged widely, from 5% to 46% in patients undergoing spinal instrumentation and fusion for adult spinal deformity. It is reported that 66% of PJK occurs within 3 months and 80% within 18 months after surgery. The reported revision rates due to PJK range from 13% to 55%. Modifiable and nonmodifiable risk factors for PJK have been characterized.
CONCLUSION
PJK and PJF affect many patients after long segment instrumentation after the correction of adult spinal deformity. The epidemiology and risk factors for the disease are well defined. A PJK and PJF scoring system may help describe the severity of disease and guide the need for revision surgery. The development and prospective validation of a PJK classification system is important considering the prevalence of the problem and its clinical and economic impact.

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.

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.

Meta-Analysis
BACKGROUND
In smaller studies, allograft-prosthetic composite (APC) has been used for proximal humerus bone loss with some success, although with notable complication risk. This systematic review and meta-analysis sought to describe outcomes and complications after proximal humerus APC and how major APC complications are defined in the literature.
METHODS
A systematic review was performed per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed/MEDLINE, EMBASE, Web of Science, and Cochrane were queried for articles on APC for proximal humeral bone loss secondary to tumor, fracture, or failed arthroplasty. Primary outcomes included postoperative range of motion, outcome scores (Musculoskeletal Tumor Society [MSTS], Simple Shoulder Test [SST], American Shoulder and Elbow Surgeons [ASES], Constant, visual analog scale [VAS], and subjective shoulder value [SSV]), and complication incidence. We also described individual study definitions of APC malunion/nonunion, methods of postoperative evaluation, malunion/nonunion rates, allograft fracture/fragmentation rates, and mean union time, when available. Secondarily, we compared hemiarthroplasty and reverse total shoulder arthroplasty.
RESULTS
Sixteen articles including 375 shoulders were evaluated (average age: 49 years, follow-up: 54 months). Fifty-seven percent of procedures were performed for tumors, 1% for proximal humerus trauma sequelae, and 42% for revision arthroplasty. Average postoperative forward elevation was 82° (69-94°), abduction 60° (30-90°), and external rotation 23° (17-28°). Average MSTS score was 82% (77%-87%), SST score 5.3 (4.5-6.1), ASES score 64 (54-74), Constant score 44 (38-50), VAS score 2.2 (1.7-2.7), and SSV 51 (45-58). There was a 51% complication rate with an 18% nonallograft surgical complication rate, 26% APC nonunion/malunion/resorption rate, and 10% APC fracture/fragmentation rate. Fifteen percent of nonunited APCs underwent secondary bone grafting; 3% required a new allograft; and overall revision rate was 12%. APC nonunion/malunion was defined in 2 of 16, malunion/nonunion rates in 14 of 16, fracture/fragmentation rates in 6 of 16, and mean union time (7 months) in 4 of 16 studies.
CONCLUSION
APC reconstruction of the proximal humerus remains a treatment option, albeit with substantial complication rates. In addition, there is a need for APC literature to report institutional definitions of nonunion/malunion, postoperative evaluation, and time to union for a more standardized evaluation.

Review
BACKGROUND
Recipient vessels proximal to the zone of injury have traditionally been preferred for lower extremity reconstruction. However, more recent data have shown mixed outcomes when performing anastomoses distal to the zone of injury. We investigated the impact of recipient vessel location on free flap outcomes.
METHODS
Retrospective review (1979-2016); 312 soft tissue free flaps for open tibia fractures met inclusion criteria. Flap characteristics and perioperative outcomes were examined. Systematic review identified articles evaluating anastomosis location and flap outcomes; pooled data analysis was performed.
RESULTS
More anastomoses were performed proximal to the zone of injury (80.7%) than distal (19.3%). Distal anastomoses were not associated with increased take back rates (19.6%) compared with proximal (23.8%) anastomoses ( = 0.356). Regression analysis comparing proximal and distal anastomoses found no difference in partial flap failures (7.4% vs 11.9%; = 0.978) or total flap failures (9.3% vs 9.3%; = 0.815) when controlling for the presence of arterial injury, flap type, and time from injury to coverage. Systematic review yielded 11 articles with 1,245 proximal and 127 distal anastomoses for comparison. Pooled analysis ( = 0.58) and weighted comparative analysis ( = 0.39) found no difference in flap failure rates between proximal and distal groups.
CONCLUSION
Our results are congruent with the current lower extremity literature and demonstrate no difference in perioperative complication rates between anastomoses performed proximal or distal to the zone of injury. These findings suggest that anastomotic location choice should be based primarily on recipient vessel quality/flow and ease of access/exposure rather than orientation relative to the zone of injury.
