ZedHip


Overview

ZedHip is 3D pre-operative planning software for THA (total hip arthroplasty).

ZedHip can create 3D models of the bone using CT data.
User can perform surgical simulations (such as positioning of implants, calculation of parameters, etc.) in simple steps.
Furthermore, ZedHip can calculate ROM (range of motion) of the hip.

In summary, ZedHip can carry out a pre-operative planning with high accuracy in about 15 minutes.

Features

Database of patient records

User can import CT data (in DICOM format) into a database application.
Patient information (such as name, sex, date of birth, etc.) can be managed uniformly.

Positioning of implants

User can select cup and stem from a library of commercially-available implants.
Implants can be placed at optimal positions on 3D model and MPR (multi-planar reconstruction) images.

Calculation of parameters

ZedHip can calculate parameters (such as anteversion, inclination, resection amount, etc.) using reference points and coordinate axes.
Results can be used intra-operatively to perform surgery accurately.

ROM Simulation

ZedHip can measure ROM of the hip and display the position of impingement.
Risk of post-operative malfunction (such as dislocation) can be reduced.

ZedHip Testimonials

“By using preoperative planning with ZedHip and our simple linked-jig to manage acetabular cup placement, we
have excellent outcomes on our total hip arthroplasty. We do not place any restrictions on our patients’ daily
activities after surgery.”

Dr. Ito, Saiseikai Niigata Second Hospital, Japan

“Even for THA experts, I believe ZedHip is very useful not only for difficult cases in revision of femur with
narrow medullary cavity but also in severely deformed hip as DDH or post osteotomy, Perthes deformity. It is
quite difficult to make an accurate preoperative plan in such a case with a conventional two-dimensional X-ray
based template software.”

Dr. Matsubara, Nissan Tamagawa Hospital, Japan

“ZedHip gives me a very clear and accurate image of surgery for respective patients before my operation. It
provides quantitative parameters like version, inclination, leg length, head offset change, and etc., all of
them in 3D! In addition, simulating the range of motion enables me to detect risky impingements among implants
and bones preoperatively and to resect osteophytes during surgery. Finally, it is very easy to use and doesn’t
take my time.”

Dr. Iwakiri, Shiraniwa Hospital Joint Arthroplasty Center, Japan

“As 3-Dimensional Templating software, ZedHip is very useful for difficult cases.
Its Range Of Motion simulation function enables us to evaluate impingement of osteophytes around acetabulum. It
shows impingement in 3D image as well as quantitative angles of femur. We could identify sizes and locations of
the osteophytes to be resected before the surgery.”

Dr. S. Kishida, Chiba University, Japan

“With 2-Dimensional templating software, it is not easy to select a suitable size and position of
implants.
3-Dimensional templating software; ZedHip is very informative with 3-Dimensional parameters such as cup
anteversion, inclination, bone quality of acetabulumn and its location to be placed, stem model and size to best
fit in femoral canal, leg length change, etc.
It brings excellent outcomes to my patients.”

Dr. Ryu, Nihon University Hospital, Japan

“Pre-operative planning by ZedHip is very useful to check and confirm acetabular coverage ratio and stem
entry location, etc. during surgery.”

Dr. Hoshino, Komaki City Hospital, Japan
