Failed previous hip surgery (not THA) where pain, deformity or dysfunction persists. Optional use in revision: in some medical conditions (e.g., early revision when healthy and good bone stock exists), the surgeon may opt to use primary implants in a revision procedure. Acute traumatic fracture of the femoral head or neck. Avascular necrosis of the femoral head. Avenir® Müller Stems are for cementless use only. The Avenir® Cemented Hip Stem is intended for total or hemi hip arthroplasty with cemented applications for rehabilitating hips damaged as a result of: Advanced wear of the joint due to degenerative, post-traumatic, or rheumatic diseases Failed previous hip surgery including joint reconstruction (osteotomy), arthrodesis, hemiarthroplasty or total hip replacement (THR) Acute traumatic fracture of the femoral head or neck Avascular necrosis of the femoral head. ## Device Story Avenir Müller Stem and Avenir Cemented Hip Stem are femoral hip prostheses designed to replace the proximal femur in total or hemi-hip arthroplasty. Müller Stem is a wedge-shaped, collarless titanium alloy implant with proximal ribs and Ti-6Al-4V plasma spray/hydroxyapatite coating for cementless fixation. Cemented Hip Stem is a highly polished, wedge-shaped, collarless stainless steel alloy implant for cemented fixation. Both feature a 3D proximal-to-distal taper and are available in standard and lateralized versions. Used in clinical settings by orthopedic surgeons to restore hip function. Output is the physical replacement of the femoral head/neck, providing structural support and stability to the hip joint. Benefits include pain relief and improved mobility for patients with degenerative or traumatic hip conditions. ## Clinical Evidence No clinical data was required or provided. Substantial equivalence is supported by non-clinical performance testing, including packaging integrity verification per ISO 11607-1:2006 and ISO 11607-2:2006, and mechanical integrity/resistance testing for reclassified instruments. ## Technological Characteristics Avenir Müller Stem: Ti-6Al-4V titanium alloy with plasma spray and hydroxyapatite coating. Avenir Cemented Hip Stem: Stainless steel alloy. Both are wedge-shaped, collarless, single-unit femoral stems with 3D proximal-to-distal taper. Sterilization via validated methods. No software or electronic components. ## Regulatory Identification A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement. ## Predicate Devices - Avenir® Müller Stem ([K123392](/device/K123392.md)) ## Reference Devices - Avenir® Cemented Hip Stem ([K131884](/device/K131884.md)) - Avenir Complete Hip System ([K182048](/device/K182048.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

August 2013. | | Device Description: | The Avenir® Müller Stem is a titanium alloy femoral stem designed to
replace the proximal femur in total or hemi-hip arthroplasty. It is a
wedge-shaped, collarless design and features a three dimensional
proximal-to-distal taper. The stem and neck are a single unit and the
stem features proximal ribs on the anterior and posterior surfaces
which are designed to increase stability. Except for the polished neck
area, the surface of the stem is coated with Ti-6Al-4V titanium alloy
plasma spray and oversprayed by a hydroxyapatite coating. The stem
is available as both a lateralized and standard version.

The Avenir® Cemented Hip Stem is a stainless steel alloy femoral

Zimmer GmbH proposes modification of the indications for use thereby limiting the indications within those of the previously cleared devices. Modification of the packaging configuration for the subject implant devices is proposed. The new packaging configuration and the methods to support the package integrity have been previously described in K182048 (Avenir Complete Hip System). The proposed changes do not alter the fundamental scientific technology shared by both the subject devices and predicate device. Zimmer GmbH is furthermore seeking clearance for certain system-specific Class II instruments these instruments that have previously considered Class I exempt and correction of classification to Class II is proposed within present submission. | |-------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Performance Data (Nonclinical and/or Clinical): | Non-Clinical Performance and Conclusions:
Packaging configuration change:
Packaging performance testing was performed to verify that packaging configuration maintains integrity of the sterile barrier system up to the point of use and provides adequate protection to the product through the hazards of sterilization, handling, distribution and storage according to ISO 11607-1:2006 and ISO 11607-2:2006. Packaging Configuration testing was conducted by representative worst-case products.
Correction of instrument classification from Class I to Class II:
Amendment of Design Controls with verification of mechanical integrity and resistance.
Clinical Performance and Conclusions:
Clinical data and conclusions were not needed for this device. | | Conclusion: | The subject devices have the same intended use and similar indications for use as the predicate device. The subject devices use the same operating principle, incorporate the same basic design and labelling and are manufactured and sterilized using the same materials and processes as the predicate device.
Except for the modifications described in this submission the subject devices are identical to the predicate device, and the performance data and analyses demonstrate that:
