    Intended Use

    The indications for use of the total hip replacement prosthesis include: noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; revision procedures where other treatments or devices have failed; and treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement, which is unmanageable using other techniques. This stem is to be press-fit.

    AI/ML Overview

    I am sorry, but the provided text does not contain information about acceptance criteria or a study proving the device meets acceptance criteria for HA Coated Hip Stems. The document is a 510(k) summary and FDA letter, which primarily focuses on establishing substantial equivalence to predicate devices for regulatory clearance, rather than detailing performance studies and specific acceptance criteria.

    The information provided only discusses:

    • The submitter's name and address
    • Device name, common name, and classification name
    • Legally marketed predicate devices
    • Subject device description and intended use
    • Technological characteristics and basis for substantial equivalence to predicate devices.
    • The FDA's decision to clear the device for market based on substantial equivalence.

    Therefore, I cannot extract the requested information regarding acceptance criteria or a study proving the device meets those criteria from the provided text.

    Intended Use

    The Linear™ Porous Coated Hip Stem is intended for treatment of patients who are candidates for total hip arthroplasty because the natural femoral head and neck have been affected by osteoarthritis, inflammatory arthritis, traumatic arthritis, rheumatoid arthritis, avascular necrosis or femoral neck fracture, and revision arthroplasty where bone loss is minimal.

    The indications for use of the total hip replacement prosthesis include: noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; revision procedures where other treatments or devices have failed; and treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement, which is unmanageable using other techniques. This stem is to be press-fit.

    Device Description

    When viewed in the mediolateral plane the Linear™ Porous Coated Hip Stem tapers slightly proximal to distal beginning at the distal border of the porous coating. Proximal to this point the stem flares approximately 6°. The stem has a rectangular cross-sectional geometry to provide rotational stability

    The Linear™ Porous Coated Hip Stem is fabricated from wrought/forged Ti-6Al-4V that conforms to ASTM F136 or F620, respectively. The outside surface of the stem is porous coated with commercially pure titanium (ASTM F67 grade 2) to provide a porous surface for enhanced fixation The stem is intended to be press-fit.

    The Linear™ Porous Coated Hip Stem is collarless and has a Morse type taper to receive modular heads. This stem is available with a standard head/stem offset and a lateralized version that provides additional lateralization of the patient's femur without increasing leg length. The stem/neck angle is 135°.

    AI/ML Overview

    The provided text is a 510(k) premarket notification for the Linear™ Porous Coated Hip Stem. This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, not for proving a device meets specific acceptance criteria through a clinical study. Therefore, the document does not contain information regarding detailed acceptance criteria, a study proving device performance against those criteria, or the other specific elements requested in the prompt (sample sizes, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance).

    The document primarily focuses on:

    • Device Description: Material, design, and intended use.
    • Predicate Device Comparison: Highlighting features comparable to existing devices.
    • Laboratory Testing: Mentioning fatigue stem strength and Morse type taper testing, but without providing acceptance criteria or detailed results.
    • FDA Clearance: A letter from the FDA stating that the device is substantially equivalent to predicate devices and can be marketed.
    • Indications for Use: The specific conditions for which the hip stem is intended.

    Therefore, I cannot provide the requested table and information as it is not present in the provided text. The information requested, such as acceptance criteria, detailed study results, sample sizes, and ground truth methodologies, would typically be found in a more comprehensive clinical trial report or a more detailed technical submission, which is not what this 510(k) summary provides.
