This study investigates the sagittal plane dynamics of the foot, particularly the metatarsophalangeal (MTP) joint and medial longitudinal arch (MLA) movements, in relation to obesity and foot health. The kinematics of the MTP and arch joints were measured in 17 individuals with class 2–3 obesity (BMI > 35 kg/m²) and 10 normal-weight individuals (BMI ≤ 24.9 kg/m²) using marker-based tracking. Analysis was conducted during heel lifting while seated and during walking at self-selected speeds. The results indicated that obese participants exhibited 20.92% greater MTP joint dorsiflexion at the end of the push-off phase and 19.84% greater MLA compression during the stance phase compared to normal-weight controls. However, no significant differences were found in the kinematic joint coupling ratio. While these findings reveal the different biomechanical behaviors of the MTP joint and MLA in obese compared to normal-weight individuals, it is important to interpret the implications of these differences with caution. This study identifies specific biomechanical variations that could be further explored to understand their potential impact on foot health in obese populations.

Background: Evidence on Versius-assisted oesophagectomy remains limited. This retrospective single-centre case series describes the early implementation and outcomes of a fully minimally invasive Ivor–Lewis procedure comprising a laparoscopic abdominal phase and a Versius-assisted thoracic phase. Methods: A retrospective analysis was performed on prospectively collected data from 34 consecutive patients who underwent the RAMIE procedure using the Versius Surgical System at Klinikum Chemnitz between September 2024 and July 2025. The surgical technique consisted of a laparoscopic abdominal phase followed by a robotic thoracic phase with intrathoracic circular stapled anastomosis. The primary aim was to assess the safety and feasibility of using the Versius Surgical System in esophageal surgery. Results: The mean operative time was 329 min (range: 245–416), and the mean docking time was 11 min (range: 6–27). No conversions to laparoscopic or open procedures occurred (0%). R0 resection was achieved in 91.2% of patients. The median lymph node harvest was 28 (range: 15–44). The anastomotic leak rate was 8.8%, with no associated mortality. No deaths occurred within 90 days after surgery. Conclusions: In this initial single-centre series, the planned robotic Versius-assisted approach was completed in all patients. The observed perioperative and pathological outcomes provide preliminary descriptive evidence to support further prospective evaluation. They do not establish comparative safety, efficacy, or oncological equivalence.
