Translumbar amputation [PDF]

open access: yesCancer, 1990
Six patients underwent translumbar amputation (TLA), a life-saving procedure, after standard modalities of therapy failed to control the progression of the disease. The primary diagnoses were as follows: pelvic arterial-venous (A-V) malformation, 1; sacral chordoma, 3; giant cell tumor of the sacrum, 1; and paraplegia with squamous cell cancer arising ...

A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

open access: yesAdvanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

Transmetatarsal Amputation Results in Higher Frequency of Revision Surgery and Higher Ambulation Rates Than Below-Knee Amputation

open access: yesFoot & Ankle Orthopaedics, 2022
Background: Selecting the level of amputation for patients with severe foot pathology can be challenging. The surgeon is sometimes confronted with an option between transmetatarsal amputation (TMA) and below-knee amputation (BKA).

A Sprayable Nanoplatform Breaks the Vicious Cycle of Diabetic Wounds via Photoactivated Antioxidant and Drug Delivery

open access: yesAdvanced Science, EarlyView.
A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...

A Retrospective Review of Risk Factors and Conversion Rate of Transmetatarsal Amputations to Below or Above Knee Amputation

open access: yesFoot & Ankle Orthopaedics, 2017
Category: Diabetes Introduction/Purpose: Despite the presence of several studies examining the conversion from transmetatarsal amputation (TMA) to a more proximal amputation, few studies identified the possible predictors of failure.

Mesoporous Catalytic‐Adsorptive Nanoregulator Orchestrates Biofilm eDNA/LPS Disassembly and TLR9/TLR4 Immune Reprogramming to Resolve Diabetic Foot Infections

open access: yesAdvanced Science, EarlyView.
Chronic diabetic wounds are hindered by a “dual trap” of biofilm resistance and hyperinflammation. A mesoporous catalytic‐adsorptive nano‐regulator is developed to dismantle this barrier through simultaneous eDNA degradation and LPS sequestration. By silencing TLR4/9‐mediated signaling, the platform clears resilient pathogens and reprograms the immune ...

A machine learning framework to classify musculoskeletal injury risk groups in military service members

open access: yesFrontiers in Artificial Intelligence
BackgroundMusculoskeletal injuries (MSKIs) are endemic in military populations. Thus, it is essential to identify and mitigate MSKI risks. Time-to-event machine learning models utilizing self-reported questionnaires or existing data (e.g., electronic ...

Cooptimized Sensing and Sole Mechanics Enable Embodied‐Intelligence Design of User‐Specific Smart Footwear

open access: yesAdvanced Intelligent Systems, EarlyView.
An embodied codesign framework for smart footwear is presented, jointly tuning lattice mechanics and sensing for personalized plantar pressure monitoring. By integrating pneumatic sensing within 3D‐printed lattice soles, the system achieves accurate real‐time centre‐of‐pressure tracking with reduced sensor count and energy demand, demonstrating how ...
