Intended Use

The EcoFit® hip stems are intended to be used in total hip arthroplasty for the following indications: - Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis; - Rheumatoid arthritis: - Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement that are unmanageable by other techniques: and - Revision of previously failed total hip arthroplasty. The EcoFit® hip stems are intended for uncemented, press-fit fixation. The EcoFit® hip stems are intended to be used in partial (hemi) hip arthroplasty in conjunction with the ic-Bipolar Head 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® short stem cementless cpTi is a line extension of the existing EcoFit® Hip System. The device consists of orthopedic hip stems designed for uncemented, press-fit fixation in the proximal femur. This submission introduces intermediate sizes (16.25 mm) in both standard and lateralized offset versions. The device is intended for use by orthopedic surgeons in clinical settings during total or partial hip arthroplasty procedures. It functions as a structural replacement for the femoral head and neck, restoring joint function and stability. The device is implanted to treat degenerative joint disease, fractures, or revision cases. Clinical benefit is derived from the restoration of hip joint mechanics and mobility.

Clinical Evidence

Bench testing only. Testing included fatigue strength (ISO 7206-4 & ISO 7206-6), range of motion evaluation, impingement testing (ASTM F2582), taper disassembly testing (ASTM F2009), fretting corrosion evaluation, and coating characterization.

Technological Characteristics

Cementless, press-fit hip stem prosthesis made of commercially pure titanium (cpTi). Available in standard and lateralized offset versions with intermediate sizing (16.25 mm). Designed for use with the ic-Bipolar Head System. Testing conducted per ISO 7206-4/6, ASTM F2582, and ASTM F2009.

Indications for Use

Indicated for patients requiring total or partial (hemi) hip arthroplasty due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures/non-union unmanageable by other techniques, and for revision of failed total hip arthroplasty.

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.
