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, atthritis 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.
Total hip systems may be indicated for use (i) without bone cement, or (ii) for use with or without bone cement. Refer to the product labeling and literature for specific applications.
The Anthology Hip System, CPCS Cemented Hip System, and Synergy Hip System are for primary surgeries only.
The TANDEM Unipolar and Bipolar Hip System is indicated for use in patients not suitable for total hip arthroplasty, with a non-functional femoral head due to femoral neck fracture.
Acetabular Hip Components are individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of degenerative joint disease or any of its composite diagnoses of osteoarthritis, avascular necrosis, and traumatic arthritis.
Hip components are also indicated for inflammatory degenerative joint disease including theumatoid arthritis, congenital dysplasia. femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques, and fracture-dislocations of the hip.
The Constrained Liners are indicated for primary or revision patients at hip dislocation due to a history of prior dislocation, bone loss, soft tissue laxity, neuromuscular disease or intraoperative instability and for whom all other options to constrained acetabular components have been considered.
The purpose of this Traditional 510(k) is the following:
-
- To add the MR safety information to the product labels and update the MR information within the package insert for the Smith & Nephew Hip Systems included within the scope of this 510(k), and
-
- To address several iterative legacy design changes made to the subject hip system components.
This document is a 510(k) premarket notification for hip system components and does not describe an AI medical device. Therefore, I cannot provide information on acceptance criteria or studies related to AI algorithms.
The document primarily focuses on demonstrating substantial equivalence of the described hip system components to previously cleared predicate devices. The "Performance Data" section specifically mentions Magnetic Resonance Imaging (MRI) compatibility testing and "additional testing [...] to assess the modifications made to the subject Smith & Nephew Hip Systems devices against their predicates." This indicates performance data related to physical device properties, not AI performance.
§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
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).(b)
