This device is intended to be used for :
- femoral 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 non-unions, femoral neck and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques.
A bipolar head which is preassembled. Outer head is made from Cobalt Chrome alloy ASTM F75 and sizes range from 38mm to 62mm in 1mm increments. An UHMW polyethylene insert will be pressed into the inner surface of the outer head during the manufacturing process. This polyethylene insert will articulate with an inner femoral head. The inner head diameter will be 22mm for outer head diameters from 38mm to 55mm and 26mm for outer diameters from 56mm to 62mm. The inner head will be pressed into the poly insert in the operating room using a bipolar head assembly device.
The provided text is a 510(k) summary for a medical device called the "Whiteside Biomechanics, Inc. Bipolar Femoral Head." It describes the device, its intended use, and confirms its substantial equivalence to a predicate device.
However, the document is a regulatory submission for a physical medical device (a hip prosthesis component), not an AI/ML-driven software device. Therefore, the information requested in your prompt (acceptance criteria, study details, sample sizes, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, standalone performance) is not applicable or present in this type of regulatory document for a physical implant. The 510(k) process for such devices typically focuses on manufacturing, materials, and substantial equivalence to existing devices, rather than the performance metrics and studies you would find for a diagnostic or prognostic AI algorithm.
Therefore, I cannot extract the requested information as it is not contained within the provided input.
§ 888.3390 Hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement (§ 888.3027) or implanted by impaction.(b)
Classification. Class II.
