• Attributes: Therapeutic

Intended Use

The Articul/eze Femoral Heads are intended to be used with DePuy femoral hip stems with Articul/eze (12/14mm) male tapers in cementless total hip arthroplasty for the indications of: a severely painful and/or severely disabled joint resulting from osteoarthritis, traumatic arthritis, or rheumatoid arthritis; avascular necrosis of the femoral head; acute traumatic fracture of the femoral head or neck; a failed previous surgery, including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or other total hip replacement; and certain cases of ankylosis.

Device Story

Articul/eze Femoral Heads are Co-Cr-Mo alloy orthopedic implants; designed for use in total hip arthroplasty; intended for attachment to DePuy femoral hip stems via internal 5°43' taper mating with stem's 5°40' external taper. Available in multiple diameters (22.225mm, 26mm, 36mm) and varying neck lengths to accommodate patient anatomy. Used by orthopedic surgeons in clinical settings; provides articulating surface for hip joint replacement. Benefits include restoration of joint function and pain relief for patients with degenerative or traumatic hip conditions.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and material similarities to legally marketed predicate devices.

Technological Characteristics

Material: Co-Cr-Mo alloy. Design: Femoral head with internal 5°43' taper. Dimensions: 22.225mm, 26mm, and 36mm diameters with various neck length offsets. Connectivity: None (mechanical implant).

Indications for Use

Indicated for patients requiring total hip arthroplasty due to severe pain/disability from osteoarthritis, traumatic arthritis, rheumatoid arthritis, avascular necrosis, acute traumatic fracture of femoral head/neck, failed previous hip surgery, or ankylosis.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

Predicate Devices

• DePuy Focus Total Hip System (K883460)
• DePuy Zirconia Articul/eze Femoral Balls (K952088)

SUBSTANTIALLY DePuy Focus Total Hip System (K883460) EQUIVALENT DEVICES: DePuy Zirconia Articul/eze Femoral Balls (K952088)

#### DEVICE DESCRIPTION AND INTENDED USE:

The subject Articul/eze Femoral Heads are Co-Cr-Mo alloy femoral heads available in: a 22.225mm diameter with +4 and +7 neck lengths: a 26mm diameter with +4, +7 and +10mm neck lengths and a 36mm diameter with -2, +1.5, +5, +8.5 and +12mm neck lengths. All of the Articul/eze taper femoral heads have an internal 5°43' taper which mates with the 5°40' external taper on DePuy Articul/eze taper femoral stems.

The Articul/eze Femoral Heads are intended to be used with DePuv femoral hip stems with Articul/eze male tapers in cemented or cementless total hip arthroplasty for the indications of: a severely painful and/or severely disabled joint resulting from osteoarthritis, or rheumatoid arthritis; avascular necrosis of the femoral head; acute traumatic fracture of the femoral head or neck; a failed previous surgery, including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or other total hip replacement; and certain cases of ankylosis.

#### BASIS OF SUBSTANTIAL EQUIVALENCE:

The listed substantially equivalent predicate device 510(k)s include Articul/eze taper cobalt-chrome alloy femoral heads in 28 and 32mm diameters and zirconia femoral heads in 26, 28 and 32mm diameters. The subject 22.225mm, 26mm and 36mm diameter Articul/eze taper cobalt-chrome femoral heads are being added to this line to give the surgeon a larger range of size and material options from which to select the best femoral head replacement for each patient. Based on similarities of design, material and intended use, DePuy believes that the subject Articul/eze Femoral Heads are substantially equivalent to the above listed predicate devices.
