The MUTARS® Proximal Femur System is intended for uncemented use in total hip arthroplasty for the following indications: - Proximal femur replacement in oncology cases where radical resection and replacement of bone is required. - Limb salvage procedures including surgical intervention for severe trauma, failed previous prosthesis, and/or oncology indications, where radical resection and replacement of the bone is required. The MUTARS® ic-Bipolar Head System is intended for uncemented use in hemiarthroplasty, where the femoral head requires replacement but the acetabulum does not, in conjunction with the EcoFit® Hip System and MUTARS® Proximal Femur Replacement System for the following indications: - Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis - Rheumatoid arthritis - Correction of functional deformity - Treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques.

Device Story

EcoFit® Hip System is a modular hip replacement system consisting of acetabular inserts and cementless femoral stems. It functions as a total hip replacement or hemiarthroplasty component. The system is used in clinical settings by orthopedic surgeons to replace the hip joint, address bone defects, or perform limb salvage. The device is implanted to restore joint function and mobility in patients with degenerative disease, fractures, or oncology-related bone loss. It integrates with the MUTARS® Proximal Femur Replacement System and MUTARS® ic-Bipolar Head System for complex reconstructions. The surgeon selects components based on patient-specific defect size and location. The device provides mechanical support and articulation for the hip joint, potentially reducing pain and improving patient quality of life.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included fatigue testing (ISO 7206-4, ISO 7206-6), impingement testing (ASTM F2582-14), liner disassembly testing (ASTM F1820), and range of motion analysis to demonstrate performance of the line extension components.

Technological Characteristics

Modular hip prosthesis components including acetabular inserts and cementless femoral stems. Materials and design are consistent with predicate EcoFit® system. Testing standards: ISO 7206-4/6 (fatigue), ASTM F2582-14 (impingement), ASTM F1820 (disassembly). Uncemented, press-fit fixation.

Indications for Use

Indicated for patients requiring total hip replacement or hemiarthroplasty due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, non-union, femoral neck/trochanteric fractures, failed previous arthroplasty, or oncology/trauma requiring limb salvage and radical bone resection.

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.

{7}------------------------------------------------

- All necessary testing has been performed for the "worst case" Performance Testing: components of the line extension of the EcoFit® Hip System to assure substantial equivalence to its predicates and to demonstrate the subject devices perform as intended. All testing was performed on test units representative of the finished device. The following testing was conducted to characterize the devices:
- Fatigue Testing (ISO 7206-4 and ISO 7206-6) .
- Impingement Testing (ASTM F2582-14) ●
- Liner Disassembly Testing (ASTM F1820) ●
- Range of Motion

#### Conclusions: The EcoFit® Hip System acetabular inserts and femoral stems subject to this submission possess the same intended use and technological characteristics as the predicate device system components. As such, the EcoFit® Hip System components are substantially equivalent for the intended use.
