IntroductionPectus excavatum, also known as “sunken chest” or “funnel chest,” is a congenital condition where the sternum caves inward, creating a noticeable depression in the chest. This deformity can range from mild to severe cases, and can affect appearance and lung and heart function. Treatment options vary depending on the severity of the condition and associated symptoms. A case study was conducted on three patients suffering from severe forms of pectus excavatum using modified taulinoplasty with two Pectus Up bars.Case descriptionThe patients were males, with an age of 15 years. Preoperatively, they underwent spirometry, an echocardiogram, and allergy tests. The procedure involved inserting two Pectus Up bars into the chest wall at the major sternal defect, allowing the implant to remain completely invisible. The procedure involved placing the sternal plate at the deepest point and anchored to the sternum with five self-tapping screws. The chest plate was then fixed to the bar using two screws.DiscussionThe use of Pectus Up was first reported in 2016 and has been a subject of scientific discussion and research. The double Pectus Up technique offers improved correction, increased stability, and reduced complications. However, it also presents challenges such as increased technical complexity and potential for prolonged operative times. Patient outcomes showed promising results in terms of short-term correction and long-term stability. The use of a double bar technique in the modified Taulinoplasty procedure is a key area of ongoing clinical research and innovation in pectus excavatum repair. Further studies will be needed, including more institutions that use this technique to validate our initial experience.

IntroductionInternational research suggests that poor patient compliance is the main cause of tutor failures in the context of potential novel orthopedic bivalve braces for conservative treatment of pectus carinatum. Our entire experimental study is based on the hypothesis that a rigid bivalve brace that patients can accept could solve the main problem associated with the conservative approach—poor compliance. The hypothesis was to reduce the thickness and weight of the classic bivalve brace to ensure concealment and make it sustainable enough to be worn several hours a day without compromising its therapeutic efficacy.Materials and methodThe research was conducted from January 2020 to December 2022 to ensure follow-up of all participants for at least 6 months. In 36 months, 140 patients with pectus carinatum were assessed and conservatively treated with the studied guardian to analyze the therapeutic efficacy of the bivalve brace and patient compliance. From the initial visit, the parents and patient were informed that this is a 2-year therapeutic course during which the bivalve brace should be worn at least 23 h a day (with 1 h of abstinence per day for routine personal hygiene practices). Compliance is the key to therapy success, and the duration of treatment depends on patient adherence.ResultsThe exceptional effectiveness of the experimental brace was confirmed by both the questionnaire from the patients (with an average satisfaction rate of 8.9/10) and an assessment of the therapy's results by a properly selected medical committee (with a VAS scale satisfaction of 7.2/10 for symmetric forms and 7.1/10 for asymmetric ones).ConclusionIn conclusion, the analyzed data confirmed the research hypotheses. First, none of the 140 patients had cardiovascular diseases directly related to their condition, confirming that pectus carinatum is a pathology of a purely aesthetic nature. Second, a cheap, lightweight, and easily obscured brace significantly improved patient compliance. Along with this, the social relevance of the aesthetic aspect today may be an important factor in motivating the study cohort to adhere to therapy. In the past, esthetics and appearance were less relevant at the social level, which may have contributed to the high abandonment and reduced compliance rates of the many studies in the literature.

Introduction: International research suggests that poor patient compliance is the main cause of tutor failures in the context of potential novel orthopedic bivalve braces for conservative treatment of pectus carinatum. Our entire experimental study is based on the hypothesis that a rigid bivalve brace that patients can accept could solve the main problem associated with the conservative approach-poor compliance.

From the initial visit, the parents and patient were informed that this is a 2-year therapeutic course during which the bivalve brace should be worn at least 23 h a day (with 1 h of abstinence per day for routine personal hygiene practices). Compliance is the key to therapy success, and the duration of treatment depends on patient adherence., Results: The exceptional effectiveness of the experimental brace was confirmed by both the questionnaire from the patients (with an average satisfaction rate of 8.9/10) and an assessment of the therapy's results by a properly selected medical committee (with a VAS scale satisfaction of 7.2/10 for symmetric forms and 7.1/10 for asymmetric ones)., Conclusion: In conclusion, the analyzed data confirmed the research hypotheses.
