Biomechanical analysis of a short femoral stem used in revision total hip replacement of a standard femoral stem.
Sci Rep
January 2025
Department of Orthopaedic Surgery, The First Affiliated Hospital of Naval Medical University: Changhai Hospital, Shanghai, China.
Short-stem total hip arthroplasty (SHA) has become popular because it preserves femoral bone stock and enables the use of short femoral stems in revision total hip arthroplasty (THA). However, no study has evaluated whether a short stem in revision THA, replacing a standard stem, can provide adequate primary stability to facilitate osseous integration. In this biomechanical study, a metaphyseal anchoring SHA (Tri-Lock BPS) stem and a standard THA (Corail) stem were implanted into ten composite femurs and loaded dynamically from 300 to 1700 N with 1 Hz.

Diabetic wound healing remains a major challenge in modern medicine. The persistent inflammation and immune dysfunction hinder angiogenesis by producing excessive ROS and increasing the susceptibility to bacterial infection. In this study, we developed an integrated strategy for whole-process management of diabetic wounds based on a bioinspired adhesive hydrogel platform with hemostasis, photothermal antimicrobial, antioxidant, anti-inflammatory, and angiogenic properties.

Urogynecology (Phila)
January 2025
Division of Urogynecology and Reconstructive Pelvic Surgery, Department of Obstetrics and Gynecology, University of Pittsburgh Medical Center, Pittsburgh, PA.
Importance: Women aged 90 years and older ("oldest-old") represent a small but growing population who may experience bothersome pelvic organ prolapse and opt for surgical repair.
Objective: This study aimed to compare perioperative adverse events (AEs) within 8 weeks of prolapse surgery between women ≥90 years and younger patients.
Study Design: We performed a secondary analysis of a dual-center retrospective cohort study of women ≥61 years old undergoing major prolapse surgery from January 2016 to May 2023.
Effectiveness and safety of negative pressure wound therapy in patients with deep sternal wound infection: a systematic review and meta-analysis.
Int J Surg
December 2024
Department of Plastic and Reconstructive Surgery, Chang Gung Memorial Hospital, Taoyuan, Taiwan and College of Medical, Chang Gung University, Taoyuan, Taiwan.
Background: Deep sternal wound infection (DSWI) is a severe and life-threatening complication following cardiovascular surgery. Negative pressure wound therapy (NPWT) has emerged as a promising therapeutic bridging option for DSWI. In this systematic review and meta-analysis, the authors aimed to evaluate the impact of NPWT on clinical outcomes in patients with DSWI.

January 2025
Department of Plastic and Reconstructive Surgery, Peking Union Medical College Hospital, Peking Union Medical College and Chinese Academy of Medical Sciences, No.1, Shuaifuyuan, Dongcheng District, Beijing, China.
Background: Perioral rejuvenation is challenging due to the lack of spatial anatomical understanding of the labiomandibular fold (LMF). The LMF's formation mechanism remains underexplored due to intricate relationships between musculature and subcutaneous structures. This study aimed to clarify the three-dimensional structures of the LMF using micro-computed tomography and histology.
