Utilization of the gastrocnemius flap for post-traumatic knee reconstruction: a systematic review.

PURPOSE: High-energy injuries to the knee may lead to extensive soft tissue loss, fractures, and potential loss of extensor function. The gastrocnemius flap is a prominent reconstructive option for patients with injuries involving the knee and proximal third of the lower extremity. To the best of our knowledge, there has not been an informative review that has evaluated outcomes of patients who have undergone post-traumatic knee reconstruction with a pedicled medial or lateral gastrocnemius flap. The goal of this study is to assess outcomes in patients who have undergone gastrocnemius flap reconstruction after traumatic injuries to the knee. METHODS: The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) methodology. Four databases were utilized including PubMed, Cochrane Reviews, Embase, and CINAHL. Our search criteria consisted of the following keywords: gastrocnemius, flap, knee, and traum*. RESULTS: A total of 204 studies were imported for screening, from which five papers met our final inclusion/exclusion criteria. The most common studies utilized in this review were case series followed by retrospective chart reviews. In total, 43 patients with traumatic soft tissue knee defects were included with an average patient age of 27.28 years. All patients had successful and clinical viable flaps post-operatively, and there were a total of five patients who had complications. CONCLUSION: The gastrocnemius flap has demonstrated to be an effective option for individuals undergoing post-traumatic knee reconstruction. Infection rates, loss of mobility, and scarring represent a minority of complications that may be seen when this reconstructive technique is utilized. Still, additional randomized controlled trials and retrospective studies are required in order to further evaluate for other potential complications that may occur in this patient population.

The new frontier: utilizing ChatGPT to expand craniofacial research.

BACKGROUND: Due to the importance of evidence-based research in plastic surgery, the authors of this study aimed to assess the accuracy of ChatGPT in generating novel systematic review ideas within the field of craniofacial surgery. METHODS: ChatGPT was prompted to generate 20 novel systematic review ideas for 10 different subcategories within the field of craniofacial surgery. For each topic, the chatbot was told to give 10 "general" and 10 "specific" ideas that were related to the concept. In order to determine the accuracy of ChatGPT, a literature review was conducted using PubMed, CINAHL, Embase, and Cochrane. RESULTS: In total, 200 total systematic review research ideas were generated by ChatGPT. We found that the algorithm had an overall 57.5% accuracy at identifying novel systematic review ideas. ChatGPT was found to be 39% accurate for general topics and 76% accurate for specific topics. CONCLUSION: Craniofacial surgeons should use ChatGPT as a tool. We found that ChatGPT provided more precise answers with specific research questions than with general questions and helped narrow down the search scope, leading to a more relevant and accurate response. Beyond research purposes, ChatGPT can augment patient consultations, improve healthcare equity, and assist in clinical decisionmaking. With rapid advancements in artificial intelligence (AI), it is important for plastic surgeons to consider using AI in their clinical practice to improve patient-centered outcomes.

Quite a Pickle: A 10-Year Increase in Pickleball-Related Hand Injuries.

BACKGROUND: Pickleball popularity has significantly increased in the United States. Wrist, hand, and finger injuries are commonly seen among pickleball players and are on the rise. METHODS: The National Electronic Injury Surveillance System database was queried from 2013 to 2022 tennis- and pickleball-related injuries in the United States. Data were filtered to include wrist, hand, and finger injuries only. RESULTS: There were a total of 12 021 estimated pickleball injuries between 2013 and 2022, most commonly in white women greater than 55 years old. The most common mechanism of injury (90.5%) was a fall. The number of injuries increased by 765.6% between 2013 and 2022. The growth in the number of pickleball-related injuries was found to be statistically significant (P < .05), whereas the growth for tennis-related injuries was found to be not statistically different from 0. There was a statistical difference between the growth of the number of pickleball injuries per year and the number of tennis injuries. The wrist was the most common location of injury (70.0%) compared with the hand (10.5%) and fingers (19.5%). The most common injury diagnosis was fracture (60.3%). Overall, the most common injury was wrist fracture (50.0%). CONCLUSIONS: Hand surgeons should be aware of the increasing prevalence of pickleball-related injuries as an alternative mechanism of injury, particularly among the elderly.

Correlations between Steady-State Pattern Electroretinogram and Humphrey Visual Field Analyzer Global Indices and Their Associations with Retinal Ganglion Cell Layer-Inner Plexiform Layer Thickness in Glaucoma Suspects.

Purpose: The purpose of this study was to investigate the utility of steady state pattern electroretinogram (ss-PERG) in detecting retinal ganglion cell (RGC) dysfunction in glaucoma suspects (GS) who had normal 24-2 Humphrey Visual Fields (HFA). Materials and Methods: This was a prospective cohort study of GS patients who were identified based on optic disc appearance with normal HFAs. Patients received a complete eye examination, standard automated perimetry (SAP), optical coherence tomography (OCT), and ss-PERG measurements. The ss-PERG parameters, Magnitude (Mag), Magnitude D (MagD), and MagD/Mag ratio, were examined, along with their relationships between HFA and OCT measurements. Results: Twenty-five patients were included in this study, with a total of 49 eyes. Fifteen eyes had abnormal ss-PERG parameters and when compared to GS eyes with normal ss-PERG parameters, there were significant differences in HFA 24-2, retinal nerve fiber layer (RNFL) thickness, and ganglion cell layer and inner plexiform layer (GCL + IPL) thickness. All ss-PERG parameters were significantly correlated with 24-2 VF mean deviation (MD) and visual field index (VFI), as well as 10-2 VF MD after controlling for age, sex, intraocular pressure, central corneal thickness, and spherical equivalent. When controlled for age, spherical equivalent, and IOP, MagD/Mag ratio significantly contributed to the variance in average GCL + IPL thicknesses, whereas 24-2 VF MD and 10-2 VF MD did not. MagD/Mag ratio also significantly accounted for variance in all macular GCL + IPL sectors, while 10-2 VF MD did not. Conclusions: ss-PERG has significant correlations with HFA global indices and was predictive of GCL + IPL thickness in GS patients. Clinical Significance. ss-PERG may serve as a useful functional tool for detecting and measuring RGC dysfunction in GS. It appears to be more sensitive than HFA in the detection of early changes in GCL + IPL thicknesses and may be helpful to use in conjunction with current diagnostic studies to improve the ability of monitoring GS progression.

The Experience of the Virtual Interview Process for Hand Fellowship Program Directors.

Purpose: Due to the Coronavirus Disease-19 pandemic, the fellowship application process has transitioned from in-person interviews to virtual interviews. Although several studies have assessed the impact of Coronavirus Disease-19 on residency and fellowship interviews, fewer studies have investigated the program director's perspective. Therefore, the aim of this study was to assess the experience of virtual interviews on hand fellowship program directors and understand some of the important factors that may make an applicant more competitive. Methods: A 21-question survey was conducted through Google Forms and distributed through a standardized email to hand fellowship program directors and coordinators. Questions used a 5-point Likert scale with the opportunity for respondents to answer some questions in a free-response format. Statistical analysis was conducted with significance assigned to P values < .05. Results: Ninety-three surveys were distributed, of which 35 responses were obtained, corresponding to a 37.6% survey response rate. Program directors reported that they tended to place more emphasis on applicant's curriculum vitae, calls from colleagues, and applicants that they had previously met. In addition, program directors felt that applicants were able to accurately represent themselves through the virtual format. Finally, most program directors stated that they were highly likely to continue to offer virtual interviews. Conclusions: With several parenting organizations and program directors affirming that they are comfortable with proceeding with virtual interviews, it is essential for hand fellowship applicants to understand what factors program directors may perceive as more important. It is possible that the virtual interview process may effectively achieve suitable matches between applicants and institutions. Type of study/level of evidence: Decision analysis IIIb.

Venous Thromboembolism Prophylaxis in Plastic Surgery.

Background: In 2011, the American Society of Plastic Surgery (ASPS) formed the Venous Thromboembolism Task Force Report, which encouraged the use of the 2005 Caprini score and was amended in 2013. Still, there have been several studies that have questioned the validity of the Caprini score. As a result, the goal of this study is to present our experience with chemoprophylaxis in cosmetic patients compared with the current recommendations for venous thromboembolism (VTE) chemoprophylaxis endorsed by the ASPS. Methods: A retrospective analysis was conducted in all patients operated on by a single surgeon from 2006 to 2016. Exclusion criteria were surgery length >6 hours, patients with known hypercoagulable states, or a personal history of deep vein thrombosis (DVT)/pulmonary embolism (PE). Demographic data were collected and analyzed. Results: There were 1272 patients from a single institution who met the inclusion criteria. We determined that 71% of patient VTE scores were in the high to highest risk categories (n = 657), median age was 46 years, 79% of the population was Caucasian, 35% of patients had a body mass index of overweight or obese, and the average length of stay was 1 day. The rate of VTE in our patient population was found to be 0.08% (1 patient), which was uncomplicated and resolved with conservative therapy. Conclusions: This retrospective study found no significant difference in the incidence of VTE by providing chemophrophylaxis to patients without utilizing a scoring system. Our study suggests that the Caprini Scoring system might not be optimal in predicting VTE in patients undergoing aesthetic surgery.

Retinal Ganglion Cell Functional Recovery after Intraocular Pressure Lowering Treatment Using Prostaglandin Analogs in Glaucoma Suspects: A Prospective Pilot Study.

Aim and background: To evaluate the ability of pattern electroretinogram (PERG) to detect improvement of retinal ganglion cell (RGC) function in glaucoma suspects (GS) after medically reducing intraocular pressure (IOP) using prostaglandin analog drops. Materials and methods: Six subjects (eight eyes) received topical IOP lowering treatment based on their clinical examination and were observed at Manhattan Eye, Ear & Throat Hospital over an average of 3.1 ± 2.2 months. During this time, participants underwent a full ophthalmologic exam and were evaluated with a Humphrey visual field analyzer (HFA) 24-2 [24-2 mean deviation (MD), 24-2 pattern standard deviation (PSD), and 24-2 visual field indices (VFI)], Diopsys NOVA PERG optimized for glaucoma [magnitude (Mag), magnitudeD (MagD), and magnitudeD/magnitude ratio (MagD/Mag ratio)] and optical coherence tomography (OCT)-derived average retinal nerve fiber layer thickness (avRNFLT) and average ganglion cell layer + inner plexiform layer (avGCL + IPL) thicknesses at baseline visit (pretreatment) and 3 months later (posttreatment). Goldman applanation tonometry was used to measure IOP at each visit. Paired sample t-tests were conducted to determine the statistical significance of the change in IOP, HFA indices, PERG parameters, and OCT thickness measurements between the two visits. Results: Lowering IOP by 22.29% resulted in a significant increase (32.98 and 15.49%) in MagD [t (7) = -3.174, 95% confidence interval (CI) = -0.53, -0.08, p = 0.016] and MagD/Mag ratio [t (7) = -3.233, 95% CI = -0.20, -0.03, p = 0.014], respectively. There was a positive percentage change for all variables of interest, however, 24-2 MD, Mag, avRNFLT, and GCL+ IPLT did not reach statistical significance. Conclusion: After reducing IOP by 22.29% for a duration of 3.1 months, the PERG parameters, MagD and MagD/Mag ratio, significantly improved by 32.98 and 15.49%, respectively. Clinical significance: Pattern electroretinogram (PERG) may be a crucial tool for clinicians to locate a window of opportunity in which degenerating yet viable RGCs could be rescued from irreversible damage. We suggest consideration of PERG as a tool in early retinal ganglion cell (RGC) dysfunction detection as well as for monitoring IOP lowering treatment.
