A Comparative Study of Doppler‐Guided Acute Bone Shortening‐Lengthening Versus Bone Transport for Infected Tibial Defects Combined With Soft Tissue Defects

Zhiming Zhao, Guoqi Ji, Chengkuo Cai, Weiguo Xu

OBJECTIVE: The management of infected tibial bone defects with soft tissue defects (ITBD-STD) remains challenging. This study aims to establish a Doppler-guided safety threshold for acute shortening (≤ 3 cm), compare the clinical efficacy and safety of shortening-lengthening (S-L) versus bone transport …

Epigenetic dysregulation in osteonecrosis of the femoral head: a critical review of DNA methylation, histone modifications, and clinical translation

Guoqi Ji, Weiying Ge, Bowen Shi, Jian Chen et autres

Osteonecrosis of the Femoral Head (ONFH) is a progressive osteoarticular disease caused by local ischemia, ultimately leading to femoral head collapse and loss of joint function. Epigenetics has emerged as a pivotal tool for unraveling the complex pathogenesis of ONFH, with DNA …

Postoperative X-ray and CT measurement of mounting parameter accuracy for hexapod external fixator in treating tibial fractures: a retrospective study

Zhiming Zhao, Zhao Liu, Yuanyuan Geng, Jian Chen et autres

BACKGROUND: The hexapod external fixator (HEF) allows for precise three-dimensional reduction of tibial fractures, but its therapeutic efficacy is highly dependent on the accuracy of postoperative mounting parameters. Currently, X-ray and computed tomography (CT) are the primary imaging modalities, each with distinct …

Double Reverse Traction‐Assisted Versus Traditional Freehand Closed Reduction With Hexapod External Fixator in Treating Open Tibial Shaft Fractures: A Retrospective Study

Zhiming Zhao, Yuanyuan Geng, Bowen Shi, Jian Chen et autres

OBJECTIVE: Open tibial shaft fractures (OTSFs) pose significant therapeutic challenges due to high-energy trauma, extensive soft tissue damage, and contamination risks, complicating fracture stabilization and increasing infection rates. Conventional freehand closed reduction often requires multiple attempts, exacerbating soft tissue injury and radiation …
