“…24 They developed a pressure-measuring device, which enables the surgeon to measure the pressure of initial correction (PIC) to correct PC as well as the pressure of treatment (POT) which may be used during application of the DCS. [24][25][26] The DCS with the pressure-measuring device permits pressure measurement during therapy (POT), prediction of treatment duration and prognosis, and in-situ outpatient clinic adjustments and avoids patient manipulation. 25,26 In the meantime, numerous studies and authors could confirm the effectiveness of the DCS.…”

For decades, open surgical repair was the only available method to treat congenital and acquired chest wall deformities (CWDs). In 1998, D. Nuss described a minimally invasive procedure for surgical repair of pectus excavatum (PE), and a few years later H. Abramson reported on his experience with the "reversed Nuss technique" for surgical repair of pectus carinatum (PC). Both procedures are performed with increasing frequency worldwide.However, nonsurgical measures such as vacuum bell (VB) therapy for conservative treatment of PE and more differentiated bracing systems for conservative treatment of PC were established 15 to 20 years ago. Nowadays, information on new therapeutic modalities circulates not only among surgeons and pediatricians, but also rapidly among patients. In particular, patients who refused operative treatment by previously available procedures now appear at the outpatient clinic and request to be considered for the new methods.Analyzing the increasing number of studies reporting on conservative treatment of CWDs as well as our own group of patients who visited a busy outpatient clinic in a small country within the last 15 to 20 years, we have to realize that the majority of patients asked for nonsurgical treatment of their CWD. Based on these experiences and results, we have to realize that nonsurgical treatment of CWD is no contradiction but a helpful complement to treat congenital and acquired CWDs and may be applied for the majority of patients suffering from a CWD.

“…Bracing has become a more common treatment for the individuals with PC [3,4,23]. The brace used in this study, the FMF Dynamic Compressor System, is adjustable and is fitted to each patient; made from curved aluminum segments, shoulder straps, cushioned compression plates, and pads to cushion the defect as shown in Fig 1 . An instrumented measuring pad is also used to assist in fitting [27,28].…”

Pectus carinatum is a chest wall deformity that is often treated through the wearing of an external brace. The treatment of the deformity could benefit from a greater understanding of chest wall characteristics under prolonged loading. These characteristics are difficult to model directly but empirical studies can be used to create statistical models. 185 patients from 2018-2020 received bracing treatment. Data on the severity of the deformity, treatment pressures, and time of wear were recorded at the first fitting and all subsequent follow-up visits. This data was analyzed using a statistical mixed effects model to identify significant measures and trends in treatment. These models were designed to help quantify changes in chest wall characteristics through prolonged bracing. Two statistical models were created. The first model predicts the change in the amount of pressure to correct the deformity after bracing for a given time and pressure. The second model predicts the change in pressure response by the body on the brace after bracing for a given time and pressure. These models show a high significance in the amount of pressure and time to the changes in the chest wall response. Initial deformity severity is also significant in changes to the deformity. The statistical models predict general trends in pectus carinatum brace treatment and can assist in creating treatment plans, motivating patient compliance, and can inform the design of future treatment systems.
