Intended Use
Hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses of osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, fracture of the pelvis, and diastrophic variant. Hip components are also indicated for inflammatory degenerative joint disease including rheumatoid arthritis, arthritis secondary to a variety of diseases and anomalies, and congenital dysplasia; treatments of nonunion, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; endoprosthesis, femoral osteotomy, or Girdlestone resection; fracture-dislocation of the hip; and correction of deformity. Smith & Nephew Redapt Revision Femoral System components are intended for single use only and are to be implanted without bone cement.
Device Description
The Redapt Revision Femoral System is comprised of a stem, modular neck, and modular sleeve component. The components of the revision hip system modularly connect together to form the complete Redapt Revision Femoral System construct. Subject of this Abbreviated premarket notification are the Redapt Modular Sleeved Revision Hip Stems and size 26/27 Modular Sleeves. The Modular Sleeved Revision Hip Stem is a modification of the MDF Revision Hip Stem cleared via premarket notification K081124. The Modular Sleeved Revision Hip Stem is a straight, tapered, distally fixed, modular stem. The subiect device is manufactured from titanium alloy (Ti-6Al-4V), has a grit-blast finish, and is available in lengths of 240mm and 300mm in sizes 11-27. The Modular Sleeved Revision Hip Stems has a modular 12/14 female neck taper that mates with the cobalt chrome modular necks previously cleared in premarket notification K0811124. The size 26/27 Modular Sleeves are line additions to the Modular Sleeves cleared in K081124. The subject devices lock onto the proximal end of the stem to aid in proximal fixation. The size 26/27 Redapt Modular Sleeves are identical in design to the current modular sleeves cleared by K081124 and are also offered in the same small, medium, and large cone sizes. The subject devices are proportionally larger to accommodate the size 26/27 stems. The subject devices contain the Smith & Nephew Stiktite coating. A Hydroxyapatite (HA) coating will be applied to the Stiktite coated areas of the size 26/27 Redapt Modular Sleeves.
More Information

No
The device description and performance studies focus on the mechanical properties and materials of the hip implant components, with no mention of AI or ML.

Yes
The device, a hip component system, is intended to rehabilitate damaged hips, treat various degenerative joint diseases, fractures, and deformities, which are all therapeutic actions.

No

The device is a hip implant system used in revision surgery, not a diagnostic tool. Its purpose is to replace damaged hip components, not to diagnose a condition.

No

The device description clearly details physical components made of titanium alloy and cobalt chrome, intended for surgical implantation. There is no mention of software as the primary or sole component.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a surgical implant for treating hip conditions. This involves direct intervention within the body.
  • Device Description: The device is described as a physical implant (stem, neck, sleeve) made of titanium alloy and coated with materials for bone integration.
  • Performance Studies: The performance studies focus on mechanical properties like fatigue strength, pull-off strength, and range of motion, which are relevant to the physical function of an implant.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.

Therefore, this device falls under the category of a surgical implant, not an in vitro diagnostic device.

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.

(a)
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.(b)
Classification. Class II.
