We consider that using this novel modular neckstem coupling design can be an alternative to the conventional monoblock stems in patients without overweight. The objective was to assess aseptic complications and functional outcome using a primary total hip arthroplasty with modular neck. Prospective cohort of 3
Modular neck adapters for hip arthroplasty stems allow the surgeon to modify CCD angle offset and femoral anteversion intraoperatively. Fretting or crevice corrosion may lead to failure of such a modular device due to high loads or surface contamination inside the modular coupling. Unfortunately we have experienced such a failure of implants and now report our clinical experience with the

Due to increased stresses at the neckstem junction modular neck fractures are more likely to occur in patients with retroverted necks and in obese or very tall patients with long necks andor high femoral offset 353642434445
A total hip arthroplasty of the left hip was performed in 2009 using a Profemur Modular stem and Conserve Cup Wright Medical Technology Inc. 5677 Airline Road Arlington TN 38002 with a long modular titanium neck with 8 degrees of varus metal on metal bearing surface and
Modular femoral prostheses are characteried by a second neckstem junction and offer the advantage of increased flexibility in component selection intraoperatively 1 2.In modular prostheses the risk of intraoperative errors in matching and disassembly of the components postoperatively are increased 3 4.Although several cases of headneck component disassembly have been reported 2 5
2020321Combining the modular Metha hip stem with OrthoPilot navigation technology expands the possibilities for endoprosthetic treatment. The free choice in the sequence of cup and stem implantation and the modular neck adapters take account of the individual joint situation resulting in the optimied range of hip motion.
20121021conserving modular neck implant that is compatible with high demand femoral head bearing options from Smith Nephew. The SMF hip stem is shorter than conventional hip stems which allows the stem to conserve more of the patients femur than other prostheses. The SMF hip stem allows for a slightly higher neck resection.

ABG II Modular Neck Performance Claims. Stryker claimed that their ABG II Modular Neck hip stem would provide patients with the following Primary Stability Stryker claimed that the anatomical shape of the ABG II Modular Neck hip stem followed the contours of the patients femur making the medical device exceptionally stable. Stryker

2016121The SROM Modular Hip System provides solutions for a variety of surgical scenarios from primary THA to the most complex revision or the challenges of Development Dysplasia of the Hip by offering independent neck and sleeve options. The SROM system utilies a straightforward surgical technique involving
We present the case of a 46yearold woman who underwent revision surgery approximately 4 years after total hip arthroplasty because of a fracture of the modular neck of a MODULUS femoral stem. The fractured surfaces of the retrieved implant were inspected using optical and scanning electron microscopy. Threedimensional finite element analysis was also performed to identify the stresses that
According to the complaint The titanium modular neck used in Mr. Parcell fractured and broke very near the femoral stem leaving a broken portion of the titanium neck wedged inside the stem. The fracture of the modular neck adapter caused failure of the system requiring corrective surgery and made it extremely difficult to extract the
Background Modular stems have been widely studied as they allow intraoperative adjustments offset anteversion limb length to better restore hip biomechanics. Many authors reported outcomes of revision total hip arthroplasty THA using modular stems with metaphysealdiaphyseal junctions however little is known about modular neck femoral stems MNFS with metaphysealepiphyseal junctions.
History of the MicroPort Profemur ModularNeck System. When a patient receives an artificial hip damaged portions of the natural hip joint are removed and replaced with prosthetic parts including a femoral head femoral stem and modular neck. The Profemur hip system is a modular system as it does not have an attached or fixed neck.
Strykers Voluntary Recall of Rejuvenate and ABG II ModularNeck Hip Stems. Hip Knee Replacements. Hip joint replacement is intended for use in individuals with joint disease resulting from degenerative and rheumatoid arthritis avascular necrosis fracture of the neck of the femur or functional deformity of the hip.

2020320The Therapeutic Goods Administration TGA advises that Stryker Australia Pty Ltd is recalling the ABGII Modular Femoral Stem and Modular Neck system used in hip replacements.. This recall is occurring worldwide because of the potential for fretting and corrosion at the join between the femoral stem and the neck component of the ABGII Modular System.
2020130Restoring leg length joint stability and range of motion involve distinct surgical challenges. The Zimmer ML Taper Hip Prosthesis with Kinectiv Technology introduces a system of modular stem and neck components designed to help the surgeon restore the hip joint center intraoperatively by addressing leg length offset and version independently.
