A bicondylar proximal tibial fracture requires a bilateral approach and dual plates for fracture fixation. Because of extensive dissection during plating and extended zone of trauma, the suture lines occasionally dehisce resulting in soft tissue defects on both sides of the proximal tibia. Because of its bilateral nature, the defect requires 2 flaps. We are reporting 2 cases of suture dehiscence after fixation of bicondylar fracture of the proximal tibia which required reconstruction with bilateral gastrocnemius flaps. This reconstruction is a simple option that helps in providing stable coverage. The first case was followed up for a period of 5 years and the second case was followed up for a minimum period of 6 months. Both cases demonstrated well-healed flaps, united bone and no donor side morbidity. Bilateral gastrocnemius muscle flaps can be used simultaneously for 2 separate defects on both sides of the knee without significant donor site morbidly. This reconstructive option provides stable coverage, reduces the infection and promotes bony union thus helping in early ambulation.</p>","PeriodicalId":20206,"journal":{"name":"Plastic surgery","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10902481/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43543147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to meet these expectations, risk factors that hinder desired outcomes, such as smoking, need to be identified and addressed. To that end, the present study summarizes an updated systematic review focused on the effects of smoking on cosmetic surgical procedures and outcomes. <b>Methods:</b> A systematic review of studies comparing aesthetic surgical outcomes by procedure, between tobacco smokers and non-smokers was carried out, querying PubMed, Embase and the Cochrane databases. Data regarding surgical outcomes were extracted and meta-analyzed by a random effects model in conjunction with the Mantel-Haenszel statistical method. <b>Results:</b> Eighty-two studies were included in the final synthesis. Abdominoplasty/panniculectomy (n = 19 cohorts) and breast reduction (n = 27 cohorts) were the most common types of procedures included in this review. Other than mastopexy and rhinoplasty, smoking conferred a statistically significant increased risk of overall complications for all studied aesthetic procedures. <b>Conclusions:</b> The data demonstrates that smoking is a clear risk factor for the vast majority of aesthetic plastic surgeries studied. Although our meta-analysis suggests that smoking is not a risk factor for complications in mastopexies and rhinoplasties, these two specific analyses may have been biased, and should therefore be re-evaluated with future additional evidence. The results of this systematic review confirm the importance of smoking cessation and education relative to the outcomes of common cosmetic surgical procedures.</p>","PeriodicalId":20206,"journal":{"name":"Plastic surgery","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10902487/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46077225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Approximately 40% of fractures were epiphyseal growth plate fractures, with Salter-Harris II fractures being the most common diagnosis overall. Management was primarily nonsurgical, with 75% of fractures managed with immobilization alone and 23% of fractures managed with bedside closed reduction and immobilization.
