Computer-Assisted Orthopedic Hip Surgery

Improvements in technology allow for improved medical procedures. During computer-assisted orthopedic surgery (CBOS), a computer guidance system helps your surgeon fit and align your new joint. A specially-designed camera is used to provide a 3D model of your hip which helps your surgeon determine which size and shape of implants will be best suited for your condition.

At Barrington Orthopedic Specialists, our experienced, high-quality surgeons use cutting-edge technology to help you find relief from hip pain and restore functionality to your joint with an artificial implant. Our team will work alongside you at every step of your surgery and help you to develop a personalized rehabilitation plan to ensure a healthy, quick recovery process.

If you’re considering computer-assisted hip surgery to treat your hip condition, schedule your first consultation with the team at Barrington Orthopedic Specialists today. If you’re in an emergency situation, visit the Immediate Care Clinic at our Schaumburg, IL location.

What Is Computer Assisted Hip Surgery?

Computer assisted orthopedic surgery (CBOS) is a surgical technology that assists surgeons through creation and display of images showing the replacement components in their relationships to the bones and ligaments of the joint being replaced. CBOS is also called Imaged Guided Surgery or Surgical Navigation. CBOS has two basic components:

  1. A special camera designed to see the surgical joint and limb and create a picture or image of the hip or knee
  2. Computer programs which integrate these images with surgical information and assist the surgeon during the operation

CBOS can use actual images of the joint (X-Rays/fluoroscopic, ultrasound or CT images) or can create virtual images of the damaged joint. The camera and computer are given information by the surgeon about the normal and abnormal anatomic landmarks of the joint and limb. This information can be transmitted in several ways. Some CBOS systems use special cameras to identify and record the position of photo reflective spheres or infra-red light emitting devices. Some other systems use ultrasonic devises to identify bony landmarks. The surgeon uses the computer generated information and images to accurately and reproducibly reconstruct the damaged joint and limb.


  • Potential benefits of using CAS/Robotics in joint replacement surgery include:
  • Computer organized and directed surgical work flow
  • Potential improved reliability of sizing and positioning of joint implants
  • Documentation of limb/joint anatomy and deformity
  • Data storage for research and outcome analysis
  • Potential improved accuracy of reconstructed limb length
  • Potential improved accuracy of prosthetic component alignment
  • Potential impact on functional outcomes and implant durability
