Taking it back: A pilot study of a rubric measuring retraction notice quality.

The frequency of scientific retractions has grown substantially in recent years. However, thus far there is no standardized retraction notice format to which journals and their publishers adhere voluntarily, let alone compulsorily. We developed a rubric specifying seven criteria in order to judge whether retraction notices are easily and freely accessible, informative, and transparent. We mined the Retraction Watch database and evaluated a total of 768 retraction notices from two publishers (Springer and Wiley) over three years (2010, 2015, and 2020). Per our rubric, both publishers tended to score higher on measures of openness/availability, accessibility, and clarity as to why a paper was retracted than they did in: acknowledging institutional investigations; confirming whether there was consensus among authors; and specifying which parts of any given paper warranted retraction. Springer retraction notices appeared to improve over time with respect to the rubric's seven criteria. We observed some discrepancies among raters, indicating the difficulty in developing a robust objective rubric for evaluating retraction notices.

Osteonecrosis of the Humeral Head 3 Years Following Fracture Fixation of a 4-Part Proximal Humerus Fracture: A Case Report.

Introduction: Osteonecrosis (ON) of the humeral head is defined as "avascular" when the death of bone is due to a disrupted blood supply. It is a known complication following proximal humeral fractures and can lead to poor long-term outcomes and even additional revision surgeries. Case Report: Patient AP developed symptomatic ON, 3 years following repair of a 4-part valgus impacted proximal humerus fracture. The point of interest in this case is the length of time from injury at which she developed symptomatic ON. Following surgical repair, she was seen at standard intervals, 6 weeks, 3-, 6-, and 12- month follow-ups and demonstrated an excellent recovery. By the 1 year follow-up appointment, she had obtained a range of motion in her left shoulder of 170° forward elevation and 60° in external rotation. At this point, she was able to discontinue physical therapy and was radiographically and clinically healed. However, 2 years after, she began experiencing sudden onset of pain with shoulder ROM and progressive limitation. She was diagnosed with an ON of her proximal humerus. The patient was prescribed a 3-month course of corticosteroid, 3 months following her operation for a gynecological-related issue. However, with strong progress being made 9 months after this prescription, and problems occurring over 2 years after taking the medication, it is unclear whether the ON was related to her fracture pattern or developed as a result of the corticosteroid usage or a combination of the 2 due to a "double hit." Conclusion: This case review points out the potential need for continued monitoring even after radiographic and clinical healing is achieved in these injuries.

The prone posteromedial approach to the knee revisited: a safe and effective strategy for posterior tibial plateau fractures.

PURPOSE: To compare outcomes of patients with posterior tibial plateau fractures who underwent repair indirectly with an anterior approach to those who underwent direct repair with a prone "Lobenhoffer" operative approach. METHODS: A total of 44 patients with a posterior column tibial plateau fracture that underwent repair were identified. Twenty-two patients with 22 tibial plateau fractures were fixed using a prone Lobenhoffer approach. They were compared to 22 patients treated with an indirect reduction using a supine approach for similar fracture patterns. Data collection at minimum 1 year included: patient-reported outcome scores (SMFA), patient-reported pain, knee range of motion, complications and need for reoperation. Radiographs were reviewed for knee alignment, residual depression and fracture healing. RESULTS: All demographics were similar between the groups except BMI, which was lower in the prone group (P < 0.05). Fracture type according to age, Schatzker and three-column classification was matched between cohorts. There was no difference in outcomes including: pain, radiographic knee alignment, residual articular depression, functional outcome (SMFA), complications and need for reoperations. Knee flexion at 1 year was greater in the prone group (127.8 vs. 115.8; P = 0.018). In addition, surgical time was less in the prone group (mean 73.7 min vs. 82.3 min; P = 0.015). CONCLUSION: The Lobenhoffer approach with direct reduction of posterior fracture fragments for complex tibial plateau fractures is an excellent option for these injuries. It allowed for faster surgery with improved ultimate knee range of motion in posterior column tibial plateau fractures.

Diagnostic Accuracy of a Trauma Risk Assessment Tool Among Geriatric Patients With Crash Injuries.

ABSTRACT: The Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) is a risk stratification tool. We evaluated the STTGMA's accuracy in predicting 30-day mortality and the odds of unfavorable clinical trajectories among crash-related trauma patients. This retrospective cohort study (n = 912) pooled adults aged 55 years and older from a single institutional trauma database. The data were split into training and test data sets (70:30 ratio) for the receiver operating curve analysis and internal validation, respectively. The outcome variables were 30-day mortality and measures of clinical trajectory. The predictor variable was the high-energy STTGMA score (STTGMAHE). We adjusted for the American Society of Anesthesiologists Physical Status. Using the training and test data sets, STTGMAHE exhibited 82% (95% CI: 65.5-98.3) and 96% (90.7-100.0) accuracies in predicting 30-day mortality, respectively. The STTGMA risk categories significantly stratified the proportions of orthopedic trauma patients who required intensive care unit (ICU) admissions, major and minor complications, and the length of stay (LOS). The odds of ICU admissions, major and minor complications, and the median difference in the LOS increased across the risk categories in a dose-response pattern. STTGMAHE exhibited an excellent level of accuracy in identifying middle-aged and geriatric trauma patients at risk of 30-day mortality and unfavorable clinical trajectories.

Tibial Plateau Fracture Surgical Care Utilizing Standardized Protocols Over Time: A Single Center's Longitudinal View.

OBJECTIVE: To report on demographics, injury patterns, management strategies and outcomes of patients who sustained fractures of the tibial plateau seen at a single center over a 16-year period. DESIGN: Prospective collection of data.Patients/ Participants: 716 patients with 725 tibia plateau fractures, were treated by one of 5 surgeons. INTERVENTION: Treatment of tibial plateau fractures. MAIN OUTCOME MEASUREMENTS: Outcomes were obtained at standard timepoints. Complications were recorded. Patients were stratified into 3 groups: those treated in the first 5 years, those treated in the second 5 years and those treated in the most recent 6 years. RESULTS: 608 fractures were followed for a mean 13.4 months (6-120) and 82% had a minimum 1-year follow up. Patients returned to self-reported baseline function at a consistent proportion during the 3 time periods. The average knee arc was 125 degrees (75 - 135 degrees) at latest follow up and did not differ over time. The overall complication rate following surgery was 12% and did not differ between time periods. Radiographs demonstrated excellent rates of healing and low rates of PTOA and improved articular reductions at healing (0.58 mm in group 3 compared to 0.94 mm in Group 1 and 1.12 mm in Group 2) (P<0.05). CONCLUSION: The majority of patients regained their baseline functional status following surgical intervention and healing. Over time the ability of surgeons to achieve a more anatomic joint reduction was seen, however this did not correlate with improved functional outcomes. LEVEL OF EVIDENCE: Prognostic Level I.

Technical Report: Reducing Lens Fogging Associated with Patient Mask Wearing with Heated Diagnostic Fundoscopy Lenses.

SIGNIFICANCE: Severe acute respiratory syndrome coronavirus 2 has indirectly created challenges to the ophthalmic retinal examinations because of lens fogging related to patients wearing masks. To date, there are no objective data on the degree of diagnostic ophthalmic lens fogging associated with mask wearing or on the effectiveness of proposed solutions to ophthalmologic lens fogging. PURPOSE: The purposes of this study were to investigate the degree of ophthalmologic lens fogging in patients wearing masks and to assess the efficacy lens warming in reducing lens fogging and facilitating ophthalmologic retinal examinations. METHODS: This study quantified the degree of lens fogging in mask-wearing subjects using ImageJ to measure lens surface area fogged in slit-lamp photographs of 90 D lenses before and after the use of a lens warmer. We investigated the clinical relevance of diagnostic lens fogging via a survey study of eye care providers. Subjects rated on a Likert scale their experience with diagnostic lens fogging during retinal examination in mask-wearing patients with and without the use of a lens warming device. RESULTS: For mask-wearing subjects, the percentage of fogged lens area in a 90 D lens averaged 32.5% using an unheated lens and 1.1% using a heated lens. Survey responders noted significantly less fogging of the 78 and 90 D lenses on retinal examination when using the lens warmer (P < .001) and found that using the lens warmer facilitated their retinal examination (P < .001). CONCLUSIONS: This study shows that there is significant fogging of ophthalmic slit-lamp lenses associated with patients wearing masks and that using a lens warmer significantly reduces fogging and facilitates retinal examinations. Eye care providers would benefit from the use of a lens warmer to reduce diagnostic lens fogging during retinal examination.

Posterior glenoid bone block transfer for posterior shoulder instability: a systematic review.

BACKGROUND: The purpose of this study is to systematically review the literature and evaluate patient-reported outcomes and complication/revision rates of bone block augmentation in the treatment of posterior shoulder instability (PSI). METHODS: PubMed was searched according to PRIMSA guidelines to find clinical studies evaluating patient-reported outcomes, revision, and complication rates in posterior bone block for PSI. A literature search of MEDLINE, EMBASE, and the Cochrane Library was performed based on the PRISMA guidelines. Clinical studies reporting on the complications following posterior bone block were included. RESULTS: Overall, 11 studies (level of evidence [LOE] III: 2, LOE IV: 9) met inclusion criteria, with 225 shoulders. Recurrent instability after the posterior bone block was found to be 9.8%. The overall complication rate was 13.8%, with 0.89% having graft complications, 11.1% having hardware complications, 0.4% having wound complications, 0.4% having nerve complications, and 0.89% having other complications. Residual pain was found in 11.6% of shoulders operated on. Patient-reported outcomes were evaluated most commonly by Rowe (81.4%), Constant (84.6%), and Walch-Duplay scores (81.6%). CONCLUSION: There is a moderate rate of recurrence following posterior bone block for PSI. However, the patient-reported outcomes are high despite there being commonly reported persistent shoulder pain postoperatively.

Short-term complications of the Latarjet procedure: a systematic review.

PURPOSE: The purpose of this study is to evaluate the short-term complication rate following the open and arthroscopic Latarjet procedures and to meta-analyze the studies comparing the 2 approaches. METHODS: PubMed was searched according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines to find clinical and biomechanical studies comparing complication rates in open and arthroscopic Latarjet procedures. A literature search of MEDLINE, Embase, and the Cochrane Library was performed based on the PRISMA guidelines. Clinical studies reporting on the complications following the open or arthroscopic Latarjet were included. Meta-analysis was performed for comparative studies using Review Manager, version 5.3. A P value of <.05 was considered statistically significant. RESULTS: Overall, 89 studies (Level of Evidence [LOE] I: 2, LOE II: 2, LOE III: 24, LOE IV: 61) met inclusion criteria, with 7175 shoulders. Following the open Latarjet procedure, the overall complication rate was 6.1%, with a 1.9% occurrence of graft-related complications, 1.1% hardware, 1.1% wound, 0.9% nerve, and 1.2% other complications. Following the arthroscopic Latarjet procedure, the overall complication rate was 6.8%, with a 3.2% occurrence of graft-related complications, 1.9% hardware, 0.5% wound, 0.7% nerve, and 0.5% other complications. Complications were reported in 7 studies comparing 379 patients treated with the open Latarjet and 531 treated with the arthroscopic Latarjet, with no statistically significant difference between the two (P = .81). CONCLUSION: Our study established that the overall complication rate following the Latarjet procedure was 6%-7%, with the most common complication being graft-related. Furthermore, based on the current evidence, there is no significant difference in the complication rate between the open and arthroscopic Latarjet procedures.
