Thoracodorsal Artery Perforator Diameter and Flow Velocity Correlate with Muscle Thickness.

Background:  The thoracodorsal artery perforator (TDAP) flap is a versatile pedicled and free flap with low donor site morbidity and a relatively thin skin paddle. Physical patient characteristics may influence interindividual differences in perforator characteristics and, therefore, help to estimate the safety of the TDAP flap.

Methods:  Dynamic infrared thermography and color duplex ultrasound were applied to assess the TDAP diameter, peak systolic velocity (PSV), end-diastolic velocity, resistance index, and thickness of the latissimus dorsi muscle and the subcutaneous tissue bilaterally in 25 subjects.

Do perilunate dislocations and fracture-dislocations result in different radiological outcomes following wrist alignment reconstruction? A single-center retrospective study including 51 patients with perilunate injuries.

Introduction: Perilunate dislocations (PLD) and perilunate fracture-dislocations (PLFD) are high-energy wrist injuries often linked to significant post-traumatic osteoarthritis. This study aims to determine whether PLD and PLFD yield different radiological outcomes following surgical treatment while identifying prognostic factors for worse outcomes.

Materials And Methods: We retrospectively analyzed 51 patients treated for perilunate injuries between 2000 and 2022.

Acute remote ischemic conditioning enhances (CD3+)- but not (FoxP3+)-T-cell invasion in the tumor center and increases IL 17 and TNF-alpha expression in a murine melanoma model.

Introduction: Hypoxia can drive tumor progression, suppress anti-tumor immunity, and reduce the effectiveness of radiotherapy and chemotherapy. This study aimed to assess the impact of remote ischemic conditioning (RIC) on tumor oxygenation (sO2) and the anti-tumor immune response.

Material And Methods: Fourteen B16-Ova tumor-bearing C57BL/6N mice received six 5-minute RIC cycles, while another fourteen underwent anesthesia only.

Patient-reported outcomes and comprehensive assessment of wrist function after scaphoid reconstruction: A single-center retrospective study on 162 patients.

A vast body of literature emphasizes the use of radiological data for assessing outcomes in scaphoid reconstruction. The goal of this single-center study was to examine patient-reported outcomes and wrist function after scaphoid reconstruction. A total of 162 of 370 patients who underwent scaphoid reconstruction between January 2007 and December 2020 were included in the study.

Postoperative scaphoid alignment, smoking, and avascular necrosis mostly influence union rate after scaphoid reconstruction: Results from a retrospective single center study involving 370 patients.

Current literature does not definitely demonstrate the superiority of any particular scaphoid reconstruction method. The primary goal of this retrospective single center study was to evaluate the influence of reconstruction techniques and other factors on the union rate after reconstruction of scaphoid nonunions. In the study, 370 patients with nonunions classified as stable (Mayo 1) or unstable (Mayo 2) depending on carpal alignment were included.
