A recent study illustrated that robot-assisted spinal implant is more safe and accurate as compare to manual for treating lumbar degenerative diseases due to osteoporosis.

A comparative study was done to compare the effectiveness of robot-assisted cortical bone trajectory (CBT) with manual one for the treatment of lumbar degenerative disorders due to osteoporosis.

In this study, 58 cases that had lumbar degenerative disease along with osteoporosis were considered. They all were given the treatment with CBT screw fixation. In group A, twenty-nine cases were treated using robot and group B, 29 cases were treated using hand.

Kaito's grading method was used to assess the accuracy of implant and Babu's method was used to analyze the invasion of CBT screw.

The blood loss during surgery and operation time in group A were considerably less than group B. 116 CBT screws were implanted in the two groups. At three days following the surgery, according to the Kaito's grading method, the difference of accuracy of the implant in group A and group B was considerable. Difference between the accepted screws in group A and group B was considerable.

There was no serious injury of the spinal cord, blood vessel and nerve was observed in the two groups. During the follow up, neurological symptoms improved, and no fracture or screw loosening was observed.

It is concluded that robot-assisted spinal implant has higher accuracy and safety as compared to implantation done with hand.
