Portland Cement01:21

Portland Cement

440
Portland cement is the essential binding ingredient in concrete, made from finely ground materials including lime, iron, silica, and alumina. Lime is derived primarily from limestone, marble, marl, seashells, and clays, which also supply iron and alumina, while silica is sourced from sand, chalk, and bauxite. Contemporary manufacturing of Portland cement is a significant source of carbon dioxide emissions, prompting research into reducing its content in concrete through alternative...

Types of Cement II

Portland blast-furnace cement is made by blending Portland cement clinker with granulated blast-furnace slag, which accounts for 25 to 65 percent of the cement's weight. Despite its similarities to ordinary Portland (Type I) cement in terms of fineness and setting times, its early strength is lower, though it achieves comparable strength later on. It's particularly suited for mass concrete structures and marine environments due to its lower heat of hydration and superior sulfate...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

4.5K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Types of Cement I01:21

Types of Cement I

267
Portland cement comes in several types, each with distinct properties and applications based on their chemical composition and hydration characteristics:
Type I (Ordinary Portland Cement) is widely used for general construction where special properties are not required. It has moderate sulfate resistance and heat of hydration.
Type II (Modified Cement) offers moderate resistance to sulfate attack and a lower rate of heat development compared to Type I. It is suitable for structures in...

Ankle Joint01:10

Ankle Joint

2.4K
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...

Knee Joint01:23

Knee Joint

2.9K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Clinical outcomes research

Background:

  • The Exeter Universal femoral component is widely used in total hip arthroplasty (THA).
  • Long-term survival data for cemented Exeter components implanted in a general hospital setting are valuable for clinical practice.
  • Assessing outcomes at 20 years provides crucial insights into implant longevity.

Purpose of the Study:

  • To evaluate the 20-year survival, clinical outcome, and radiological appearance of cemented Exeter Universal femoral components.
  • To assess the long-term performance of this implant in a district general hospital cohort.
  • To provide evidence supporting the durability of cemented THA components.

Main Methods:

  • A prospective cohort study of 225 cemented Exeter Universal femoral components in 207 patients undergoing THA.
  • Clinical and radiological data were collected prospectively over 20 years.
  • Revision rates were cross-referenced with national registries and general practitioner records.

Main Results:

  • Femoral component survival, using loosening as an endpoint, was 98.7% at 20-22 years.
  • Overall survival with revision for any reason was 92.6% at 20-22 years.
  • Revision rates for femoral failure, periprosthetic fracture, and acetabular loosening were low.

Conclusions:

  • The cemented Exeter Universal femoral component demonstrates excellent long-term results.
  • The implant's performance is favorable even when implanted outside its originating center.
  • These findings support the continued use of cemented Exeter components in THA.
