• Device Name: AVENIR MULLER STEM
• Applicant: Zimmer GmbH
• Product Code: LZO · Orthopedic
• Decision Date: Mar 4, 2013
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3353
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Advanced wear of the joint due to degenerative, post-traumatic or rheumatic diseases. Failed previous hip surgery including joint reconstruction (osteotomy), arthrodesis, hemi-arthroplasty or total hip replacement (THR). Acute traumatic fracture of the femoral head or neck. Avascular necrosis of the femoral head. Avenir Müller Stems are for cementless use only.

Device Story

Avenir Müller Stem is a titanium alloy femoral stem for total or hemi-hip arthroplasty. Device features wedge-shaped, collarless design with proximal-to-distal taper; available in lateralized and standard versions. Surface includes polished neck area; remainder coated with air plasma sprayed (APS)-Ti and hydroxyapatite. Implanted by orthopedic surgeons in clinical settings to replace proximal femur. Provides structural support for hip joint reconstruction; benefits patients by restoring joint function and mobility in cases of degenerative disease, fracture, or necrosis.

Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical bench testing including proximal and distal stem fatigue, pull-off strength, hydroxyapatite and plasma spray coating characterization, burst strength, and range of motion analysis.

Technological Characteristics

Titanium alloy femoral stem; wedge-shaped, collarless, proximal-to-distal taper. Surface finish: polished neck; body coated with air plasma sprayed (APS)-Ti and hydroxyapatite. Cementless fixation. No software or electronic components.

Indications for Use

Indicated for patients requiring total or hemi-hip arthroplasty due to degenerative, post-traumatic, or rheumatic joint wear; failed prior hip surgeries (osteotomy, arthrodesis, hemi-arthroplasty, or THR); acute traumatic femoral head/neck fractures; or avascular necrosis of the femoral head. For cementless use only.

Regulatory Classification

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.

The Avenir® Müller stem is a titanium alloy femoral stem designed to replace the proximal femur in total or hemi-hip arthroplasty. Except for the polished neck area, the surface of the stem is coated with air plasma sprayed (APS)-Ti and oversprayed by a hydroxyapatite coating. It is a wedge-shaped, collarless design with a proximal-to-distal taper. The stem is available as both a lateralized and standard version.
