SUMMIT®  Tapered Hip System 

The SUMMIT® Tapered Hip System has achieved over 15 years of clinical history1, and it remains a viable treatment option for patients today. The SUMMIT Tapered Hip System utilizes a common set of instrumentation. The streamlined approach maximizes efficiency in the operating room, while still providing intraoperative flexibility.

Features & Benefits

  • POROCOAT™ Porous Coating

    POROCOAT™ Porous Coating

    POROCOAT Porous Coating allows biological fixation without the use of bone cement.2 With more than 30 years of clinical heritage, our proprietary POROCOAT Porous Coating is composed of commercially pure titanium sintered metal beads. This technology is available on the SUMMIT POROCOAT Cementless Stem.

    Radial ZTT Steps

    Radial ZTT Steps are designed to convert hoop stresses to compression loads which may potentially reduce the risk of intraoperative fracture.3

  • close-up of leg stem  connection for direct lateralization

    Direct Lateralization

    SUMMIT Hip Dual Offset options provide surgeons the ability to lateralize by 6mm-8mm to help manage soft tissue laxity. The offset range is 30mm-50mm depending on stem size. This direct lateralization can enable femoral offset restoration without affecting leg length.
