Basic Plant Anatomy: Roots, Stems, and Leaves02:27

Basic Plant Anatomy: Roots, Stems, and Leaves

The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species.
Light Acquisition02:16

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
Meristems and Plant Growth02:36

Meristems and Plant Growth

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Epiphytes, Parasites, and Carnivores02:40

Epiphytes, Parasites, and Carnivores

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the biosynthesis of the...
Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Summary
This summary is machine-generated.

Short tapered stems offer excellent outcomes in total hip arthroplasty (THA). They provide equivalent clinical results to standard stems while significantly reducing femoral fractures and revisions, representing a logical advancement.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Implant Design

Background:

  • Standard-length porous-coated tapered femoral stems demonstrate long-term success in primary total hip arthroplasty (THA).
  • Emerging short tapered stem designs present potential advantages over traditional lengths.
  • Optimal femoral stem length for proximal femur loading remains an area of investigation.

Purpose of the Study:

  • To evaluate the clinical outcomes and complications of short tapered femoral stems in THA.
  • To compare the performance of short tapered stems against standard-length tapered stems.
  • To identify the benefits and potential advantages of utilizing short tapered stems in primary THA.

Main Methods:

  • Retrospective analysis of 1750 total hip arthroplasties (THAs) performed since 2006.
  • Comparison of clinical outcome scores between short and standard-length tapered stems in over 650 THAs.
  • Assessment of complication rates, specifically femoral fractures and revisions, at 2-year follow-up.

Main Results:

  • Short tapered stems achieved equivalent clinical outcome scores compared to standard-length stems.
  • A significantly lower incidence of femoral fractures was observed with short stems (0.4%) versus standard stems (3.1%).
  • Only one femoral revision (infection) was required in the short stem group at 2-year follow-up.

Conclusions:

  • Short tapered femoral stems are a logical progression from standard-length tapered stems, offering comparable clinical results.
  • Short stems demonstrate a reduced risk of intraoperative femoral fractures and fewer revisions.
  • The use of short tapered stems may facilitate less invasive approaches and provide favorable revision options.
