## Intended Use

The Hemisphere™ Cemented Cup is intended for single use with bone cement in primary or revision arthroplasty surgery. Indications include: - Osteoarthritis, rheumatoid arthritis, or other osteoarthroses of the hip joint; - Certain femoral neck fractures; - Idiopathic avascular (osteo) necrosis; - Post-traumatic arthritis; - Benign or malignant bone tumors where sufficient bone is present to seat the prosthesis; - Previously failed implant

## Device Story

Hemisphere™ Cemented Cup is an acetabular component for hip arthroplasty; designed for single-use with bone cement. Used in primary or revision surgery to replace diseased or damaged hip joints. Operates as a mechanical prosthesis; provides a bearing surface for femoral heads. Used by orthopedic surgeons in hospital settings. Integrates with Primaloc™ Cemented Hip and Headloc™ CoCr femoral heads; compatible with other cleared hip prostheses. Benefits patients by restoring hip joint function and mobility.

## Clinical Evidence

No clinical data provided; substantial equivalence based on bench testing and design comparison to predicate devices.

## Technological Characteristics

Acetabular cup for cemented hip arthroplasty. Materials and dimensions consistent with standard orthopedic hip prostheses. Designed for use with bone cement. No software or electronic components.

## Regulatory 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

- Primaloc™ Cemented Hip ([K962448](/device/K962448.md))
- Headloc™ CoCr femoral heads ([K953977](/device/K953977.md))
