Ankle Joint01:10

Ankle Joint

3.0K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

1.0K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Total Voids in Concrete01:12

Total Voids in Concrete

485
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

13.4K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

219
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Engineering

Background:

  • Revision total ankle replacement is necessary due to complications like subsidence and loosening of existing implants.
  • The Agility total ankle replacement is a common implant necessitating revision surgery.

Purpose of the Study:

  • To describe a surgical technique for revision total ankle replacement.
  • To address the challenges of subsidence and loosening in failed Agility total ankle replacements.

Main Methods:

  • Utilizing the prior anterior midline incision with full-thickness flaps to expose the joint.
  • Careful removal of talar and tibial components, preserving tibial cortex integrity.
  • Employing a cutting block for talar bone cuts and managing bone defects with impaction bone-grafting.
  • Simultaneous insertion of trial components and manual cement insertion for revision arthroplasty.

Main Results:

  • The described technique effectively addresses subsidence and loosening in revision total ankle arthroplasty.
  • Previous outcomes of revision for failed Agility total ankle replacements in forty-one patients were reported.

Conclusions:

  • The described surgical technique provides a viable solution for revision total ankle replacement.
  • Careful surgical technique and bone management are crucial for successful revision arthroplasty outcomes.
