A Hip Prosthesis Bipolar Head Liner — sometimes referred to as a Bipolar Hip Head Insert — is a key component in partial hip replacement surgery. It consists of a dual-layer (bipolar) articulation design that allows smooth movement between the femoral head and the outer shell, helping reduce friction and enhance motion stability.
It is widely used in partial hip arthroplasty and clinical scenarios requiring reduced femoral head friction or improved joint motion. JinMing’s Bipolar Head Liner is engineered to support surgical efficiency by providing smooth rotational mobility, strong structural stability, and high assembly compatibility. Manufactured with medical-grade materials, it is available in multiple sizes to match different patient anatomies.
Double-layer rotating interface design: Provides stable motion mechanics and reduces friction between articulating surfaces.
High-strength medical materials: Ensures long-term mechanical performance and wear resistance.
Precision-fitted dimensions: Creates a secure connection between the femoral head and the bipolar outer shell.
Smooth inner and outer cup surfaces: Supports continuous and unrestricted joint movement.
Multiple size options: Easily adapts to various clinical needs and implant combinations.
Excellent system compatibility: Works with different chamber volumes and femoral head specifications.
The Hip Prosthesis Bipolar Head Liner — a reliable Bipolar Hip Liner option — is commonly used in:
Partial hip replacement for femoral neck fractures
Degenerative joint disease requiring reduced femoral head friction
Elderly patients needing a dual-mobility–type articulation
Clinical cases requiring a stable, low-friction interface without full total hip replacement
Combined use with JinMing femoral head implants and hip surgery instrument sets to optimize hip arthroplasty workflow
