Origin Cemented Hip Stem
Components of the Signature Orthopaedics hip replacement range are intended to replace a hip joint where bone stock is sufficient to support the implant. When a surgeon has selected prosthetic replacement as the preferred treatment, the devices are indicated for:
- Non-inflammatory degenerative joint disease including osteoarthritis or avascular necrosis
- Inflammatory joint disease including rheumatoid arthritis
- Correction of functional deformity including congenital hip dysplasia
- Traumatic injury involving the hip joint including traumatic arthritis or femoral head or neck fracture
- Failed previous hip surgery including internal fixation or joint fusion, reconstruction, hemiarthroplasty, surface replacement, or total replacement
Signature Orthopaedics' Origin, Origin TT, Aria, Remedy, Origin-NS, Pegasus, Spartan, World and Everglade Hip femoral stems, SignaSure Cementless Cups, Logical and World Acetabular Cups are intended for cementless fixation only.
Signature Orthopaedics' Evolve, Cemented TSI (both CoCr and HNSS variants), and Origin Cemented femoral stems and SignaSure Cemented Cups are intended for cemented fixation only.
Signature Orthopaedics' SignaSure Logical/World Metal Insert is indicated for use with a cementless Signature Orthopaedics' Logical/World Acetabular Cup to provide dual mobility articulation.
Signature Orthopaedics' constrained liner components are indicated particularly for patients at high risk of hip dislocation due to a history of prior dislocation, bone loss, joint or soft tissue laxity, neuromuscular disease or intraoperative instability.
Signature Orthopaedics' Evolve UniPolar Head and BiPolar Head are intended for hemi-hip arthroplasty only, where the natural acetabulum does not require replacement. The Evolve UniPolar Head and BiPolar Head are indicated for bone fractures or pathologies involving only the femoral head/neck and/or proximal femur, such as:
- Acute femoral head or neck fracture
- Fracture dislocation of the hip
- Avascular necrosis of the femoral head
- Non-union of femoral neck fractures
- Certain high subcapital and femoral neck fractures in the elderly
- Degenerative arthritis involving only the femoral head
Signature Orthopaedics' Origin™ Cemented Hip Stems are manufactured from nitrogen stainless steel per ASTM F1568 and ISO 5832-9. The subject stem is straight and tapered with a lateral chamfer. The Cemented Origin™ stem is polished and intended for cemented use in total hip arthroplasty. It features a 12/14 taper which allows for compatibility with Signature Orthopaedics' range of previously cleared femoral head components including the Signature CoCr Femoral Heads (K121297 and K163081), Signature Ceramic Femoral Heads (K190704), Signature BiPolar Head (K133370 and K163081) and Evolve UniPolar Head (K143184). Compatible acetabular cups and liners including the Logical Cup (G-Series K121297, PX-Series K121297 and C-Series K153131) and the Logical Liners (Neutral and 10º Hooded, Lateralised K121297), Logical Liners (20º Hooded, Lateralised 20º Hooded K153131), Logical Constrained Liners (K153131) and Logical Liners Vit-E (Neutral and 10º Hooded, Lateralised, 20º Hooded, Lateralised 20º Hooded, High Wall, 10º Face Changing (K241690).
Based on the provided FDA 510(k) Clearance Letter for the Origin™ Cemented Hip Stem, there is no information present regarding acceptance criteria or a study proving that the device meets specific acceptance criteria in the context of an AI/human reader performance study.
This document is a 510(k) clearance for a physical medical device (a hip stem), not a software or AI-enabled device that would typically involve acceptance criteria related to accuracy, sensitivity, specificity, or human reader performance. The "Performance Testing" section refers to non-clinical mechanical and fatigue testing of the physical hip stem, not a clinical or human-in-the-loop study as described in your request.
Therefore, I cannot populate the table or answer the specific questions related to acceptance criteria, sample sizes for test sets, expert involvement, adjudication, MRMC studies, standalone performance, or ground truth establishment for AI/human reader studies.
If you have a document related to an AI/software device, please provide that, and I would be happy to analyze it against your criteria.
