As total hip arthroplasty is now applicable for younger, healthier, and more active patients, bone preservation becomes even more essential, and proximal fixation, resulting in less stress shielding, draws special attention with focus on new strategies and implant designs.
Within the 4-year study of implant-supported overdenture, preservation and gaining of more bones were preserved.
Hemiarthroplasty is a potentially attractive alternative to knee replacement for young, active patients, as it allows preservation of more bone stock for potential revisions.
Such studies suggest that alveolar bone may be much more sensitive to strategies targeting systemic bone preservation in the preclinical model of postmenopausal bone loss than previously thought.
Likewise, studies on steroidal estrogens used in hormone replacement have shown that some B-ring unsaturated compounds have distinct tissue-selective actions, being more efficacious in vasomotor, neuroendocrine and bone preservation parameters than in other peripheral actions of estrogens [ 28*].
MoM HRA offers potential advantages over conventional THA in terms of femoral bone preservation and ease of future revision surgery, especially in younger, more active patients who are more likely to require revision surgery.
You want more bone, boss?
The Nanos stem requires a higher neck osteotomy and more proximal filling to achieve, with a rounded cross-section, a primary stability, both axial and torsional: this last aspect apparently reduces the validity of proximal cancellous bone preservation (Fig. 4).
Many of the articles reported bone preservation with implant-assisted restorations, and the rest denoted noticeable bone apposition.
Articles reported bone preservation or bone apposition even in clinical notifications or in the context were included.
