Read the full statement (143 words)

The Conformis Hip System is designed from a patient’s pre-operative CT scan which must include certain necessary anatomic landmarks that are clearly identifiable. Total hip replacement using the Conformis Hip System is indicated for use in skeletally mature individuals undergoing total hip replacement due to:

• A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, avascular necrosis, or congenital hip dysplasia.

• Treatment of non-displaced non-unions of the hip, femoral neck fractures, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques.

• Revision procedures for failed previous hip surgery (excluding situations where hardware is present).

The Conformis Hip System includes standard hip replacement components as well as the following patient specific components: femoral stem and single use instrumentation.

The Conformis Hip System implants are intended for cementless fixation using an anterior or posterior surgical approach.

Indications for use as stated in the FDA summary.
