Total Hip Replacement
Patient-specific drilling guides for hip replacement
SurgiNovi’s SurgiHip PST is a patient-specific drilling guide associated with acetabular cup fixation. CT imaging is used to represent the pelvis for planning, including consideration of the proposed cup orientation and screw trajectories.
The published SurgiHip configuration includes bone-matching arms, fixation features and trajectory guide holes. The product illustrations show designs associated with the ischium and pubis. The relevant configuration depends on the plan for the particular case.
Planning around pelvic anatomy
The proposed cup position and fixation need to be considered against the individual anatomy. A digital reconstruction provides a reference for discussing the relevant bone surfaces and planned directions.
The surgeon determines the reconstruction strategy. Patient-specific design then needs to correspond with that strategy and the selected component. If the planned implant or fixation changes, the implications for the guide should be reviewed.
The guide’s defined role is drilling guidance. It should be distinguished from a cutting template and from the acetabular implant itself. That distinction helps make the intended instrument sequence clear during planning.
Questions about SurgiHip PST
Is the guide a custom-made implant?
No. It is an instrument for a defined drilling task. The custom-made implants page describes a separate product category, including an acetabular implant example.
Where is the broader planning workflow explained?
The 3D planning software page introduces our digital tools. The anatomical models page explains physical representations of patient anatomy, and the template overview places the hip guide within the wider instrument range.

SurgiNovi Custom-Made Patient-Specific Acetabular Drilling Guide
SurgiNovi SurgiHip PST is a patient-specific drilling guide designed for acetabular cup fixation during hip replacement surgery. This innovative device utilises CT scan data to create a 3D model of the patient’s pelvis, allowing for precise preoperative planning of cup anteversion and abduction.
