No hip subsided > 2 mm. Jun 30, · When performing cementless hip arthroplasty, it is critical to achieve firm primary mechanical stability followed by biological fixation. In order to achieve this, it is essential to fully understand characteristics of implant design. The tapered- wedge design of the TRI- LOCK BPS Stem ensures intimateimplant to bone contact proximally, providing both rotational and axial stability, while increasing the opportunity for biological fixation to bone. Spot welds were present in 99. The Entrada Hip Stem integrates a wealth of clinical history— hydroxyapatite coating, compaction broaching, taper wedge geometry— and provides critical refinements— progressive neck lengths, consistent proximal body growth, shorter distal stem lengths— creating a dynamic combination of features that benefit patient and surgeon. The TRI- LOCK ® Bone Preservation Stem is based on the well documented 35 year clinical heritage of the original TRI- LOCK Stem. Proximally coated femoral stem in total hip arthroplasty. Femoral Hip Stem. This design is also known as the Double wedge stem. Implant was the first proximally coated tapered wedge hip stem available to orthopaedic surgeons and their patients. Alteon Tapered Wedge Femoral Stem Incorporates specific design features to achieve immediate axial and rotational mechanical stability between the lateral and medial cortices of. Taperloc® microplaSty™ Stem tHe next DimenSion in taPErEd WEdgE dEsign the taperloc® microplasty™ Hip System is the next dimension in the evolution of Biomet’ s flat tapered wedge design philosophy. This was most common adjacent to the porous coating.
Calcar atrophy was noted in 93 hips ( 72% ) : above the level of the lesser trochanter in 82 hips and to the level of the lesser trochanter in 11 hips. Since its introduction, the success of the TRI- LOCK Stem has been well documented in published studies. The Novation ® Element’ s ® tapered- wedge stem philosophy and its extensive hydroxyapatite coating, utilizes design and surgical technique principles based upon more than 25 years of clinical use. Morphometric wedge femoral stem, an evolution of your conventional tapered wedge stem that is SOMA- designed for today’ s diverse THA patient population. The stem tapers in anteroposterior and. Hip “ The Corail Revision Hip System is designed to treat patients in need of hip revisions who have mild to moderate femoral defects, ” according to the press release The company states that the Corail is the first and only tapered wedge revision stem in the U. Cementless titanium tapered- wedge femoral stem:. To evaluate the accuracy of shorter stem orientation, we focused on the accuracy of stem orientation especially in short tapered wedge stems and evaluated the contribution factors of stem malalignment during mini- invasive total hip arthroplasty. Reported with Uncemented Tapered Total Hip Stem. Orthopedics Today. Wedge hip stem. TAPERED WEDGE FEMORAL STEM.
The TRI- LOCK Bone Preservation Stem’ s 12/ 14 ARTICUL/ EZE. 1 day ago · Other than the fact that tapered wedge stems are not appropriate in all patients, such as patients with a Dorr C or a violated hip, “ I think it’ s a go- to stem in all Dorr A and B bone, whether. Cementless Tapered- Wedge Stem Length Affects the Risk of Periprosthetic Femoral Fractures in Direct Anterior Total Hip Arthroplasty. The taperloc® microplasty™ Hip builds on the strong clinical heritage of. Flat Tapered Wedge Geometry Enhances proximal offloading and bone preservation and provides for rotational stability Reduced Distal Transition Enhances implant fit in femoral canals with a. The concept of tapered wedge femoral stems has been shown to provide excellent implant stability in short term, mid term and long term clinical studies.
[ 1, 2, 3] The MasterLoc Hip System follows this philosophy, presenting a novel proximal coating - Mectagrip, designed for initial stability and long term fixation.
