Summary
Calcar-guided short stems in total hip arthroplasty (THA) allow precise reconstruction of hip offsets. This technique, while offering anatomical advantages, may present a learning curve and requires careful positioning to ensure stability and optimal bone remodeling.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Short stems are gaining popularity in total hip arthroplasty (THA) for bone- and soft-tissue sparing.
- Various short stem designs exist, with calcar-guided stems offering unique anatomical alignment capabilities.
Purpose of the Study:
- To demonstrate the implantation technique for calcar-guided short-stem THA.
- To present short-term clinical and radiological outcomes of this THA approach.
Main Methods:
- Detailed description of the calcar-guided short-stem implantation technique, emphasizing the "round-the-corner" positioning.
- Evaluation of short-term clinical data and radiological results following the procedure.
Main Results:
- Calcar-guided short stems facilitate precise reconstruction of femoro-acetabular offsets by accommodating diverse caput-collum-diaphyseal (CCD) angles.
- The "round-the-corner" technique allows for individual stem alignment within a broad range of varus and valgus anatomies.
Conclusions:
- Calcar-guided short-stem THA offers precise anatomical reconstruction and offset restoration.
- Further investigation is warranted regarding the long-term stability and bone remodeling associated with extensive varus/valgus positioning in this technique.

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
