Intended Use

The MSA Hip System is indicated for cementless use and is intended to replace a hip joint. The device is intended for: - skeletally mature individuals undergoing primary surgery for total hip replacement - patients suffering from severe hip pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral head and nonunion of previous fracture of the femur. - patients with congenital hip dysplasia, protrusio acetabuli, or slipped capital femoral epiphysis - patients suffering from disability due to previous fusion - patients with acute femoral neck fractures

Device Story

Modular hip prosthesis system; replaces hip joint. Components: short stem (Ti-6Al-4V), modular neck (CoCr alloy), and femoral head (metal or ceramic). Stem features proximal plasma spray coating; optional hydroxyapatite coating. Device implanted by orthopedic surgeons in clinical/OR setting. System provides structural replacement for damaged hip joints; restores joint function; alleviates pain. Ceramic femoral head addition represents design modification to existing system.

Clinical Evidence

Bench testing only. Burst strength testing performed on the ceramic femoral head to verify mechanical integrity.

Technological Characteristics

Modular hip prosthesis. Materials: Ti-6Al-4V (ASTM F136) stem, CoCr alloy (ASTM F1537) neck, ceramic or metal femoral head. Surface: Commercially pure titanium plasma spray (ASTM F1580) on proximal stem; optional hydroxyapatite coating. Non-software device.

Indications for Use

Indicated for skeletally mature individuals requiring primary total hip replacement due to severe hip pain/disability from rheumatoid/osteo/traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis, nonunion of femoral fracture, congenital hip dysplasia, protrusio acetabuli, slipped capital femoral epiphysis, previous fusion, or acute femoral neck fractures.

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.

# Reason for Special 510(k) Submission:

The purpose of this Special 510(k) is to add ceramic femoral heads to the MSA Hip System. There have been no changes to the intended use of the device or its fundamental scientific technology.

# Indications For Use:

The MSA Hip System is indicated for cementless use and is intended to replace a hip joint.

The device is intended for:

- · skeletally mature individuals undergoing primary surgery for total hip replacement
- · patients suffering from severe hip pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral head and nonunion of previous fracture of the femur.

- · patients with congenital hip dysplasia, protrusio acetabuli, or slipped capital femoral epiphysis
- · patients suffering from disability due to previous fusion
- · patients with acute femoral neck fractures

### Device Description:

The MSA Hip System is a modular hip system consisting of a short stem which mates with a modular neck. The hip stems are made of Ti-6AI-4V (ASTM F136) with a commercially pure titanium plasma spray coating (ASTM F1580) on the proximal end. The stems are available with and without a hydroxyapatite coating. The modular necks are made of CoCr alloy (ASTM F1537). The MSA Hip System can be mated with metal or ceramic femoral heads and acetabular components.

#### Predicate Devices:

The modified MSA Hip System is substantially equivalent to the predicate MSA Hip System (K102172) with respect to indications, design, and function.

#### Substantial Equivalence:

The company performed burst strength testing of the ceramic femoral head. The test results demonstrate that the pre-determined acceptance criteria identified in the Design Control Activities Summary were met.

#### Conclusion

The MSA Hip System when mated with a ceramic femoral head is substantially equivalent to previously cleared devices with respect to its indications for use, design, and function.
