Pilot study on the feasibility of shape memory alloy implantation for Vancouver type B1 periprosthetic femoral fractures in a canine model: a step toward advancing treatment modalities.

Background: Cerclage wiring is commonly used for treating fractures; however, it has several limitations, including mechanical weakness, decreased blood circulation, and technical complexity. In this study, we developed an implant using a shape memory alloy (SMA) and tested its efficacy in treating Vancouver type B1 (VB1) periprosthetic femoral fractures (PFFs) in a canine model.

Methods: The mid-diaphyseal fracture models underwent reduction via the SMA plate (SMA group) or the cerclage cable plate (cable group) method in randomly selected pelvic limbs.

Performing a radical trachelectomy with uterine transposition in a patient with stage IB2 cervical cancer: A case report.

We describe a case of a woman with invasive IB2 cervical cancer who desired to maintain fertility and required complex treatment. The suggested surgical approach with uterine transposition improves the existing radical trachelectomy procedure. Oncologic outcomes are encouraging, and no perioperative complications were noted.

[Reconstruction of post-resection chest wall defects in surgical treatment of invasive non-small cell lung cancer].

Objective: To present the results of reconstruction of post-resection chest wall defects with nickel-titanium (TiNi) implants in patients with invasive NSCLC and to analyze the features of perioperative management.

Material And Methods: We enrolled 9 patients with NSCLC involving the ribs after lobectomy or pneumonectomy with chest wall reconstruction. Defects were closed used TiNi mesh and rib prostheses.

Treatment of post-resuscitation cicatricial tracheal stenosis after suffering severe COVID-19 associated pneumonia: A report of 11 cases.

Objective: Despite the full range of anti-epidemic measures, the rapidly mutating SARS-CoV-2 continues to spread worldwide, causing respiratory and pulmonary pathologies. So far, there are no generally accepted clinical guidelines for treating post-resuscitation cicatricial tracheal stenosis (CTS) after COVID-19 associated pneumonia. This study sought to evaluate the clinical outcomes of surgical treatment and perioperative management of patients who developed CTS.

Repair of huge thoracic defect combined with hernia after multimodality treatment of breast cancer.

A case of the successful reconstruction of an extensive chest wall defect combined with a ventral hernia in a patient after multimodality treatment of breast cancer complicated by sternal and costal osteomyelitis is presented. To recover the chest mechanics, with emphasis on the supporting function, and to repair the hernial defect, customized reinforced "sandwich" TiNi rib endografts and knitted TiNi surgical mesh were used. A five-year follow-up indicated no recurrence of osteomyelitis or ventral hernia, and no failure/migration of the implants or instability of the thorax.
