Robot-assisted MIS transiliac sacroiliac joint fusion: Technical note
Background:
Sacroiliac joint dysfunction (SIJD) accounts for 15-25% of chronic low back pain and often follows lumbar fusion. When conservative therapies fail, minimally invasive (MIS) SIJ fusion (SIJF) is indicated. The robot-assisted technique is feasible and safe, enhancing accuracy and reducing radiation exposure.
Case Description:
A 26-year-old woman, eight years after L4-S1 fusion, presented with bilateral SIJD refractory to physiotherapy and intraarticular steroids injection. SIJF was indicated. Here we describe the robot-assisted technique and its advantages.
Conclusion:
Robot-assisted SIJF is a safe and accurate technique to treat SIJD while reducing radiation exposure. Trajectories planification and consideration of anatomical variations give the robot-assisted technique an advantage over conventional techniques such as fluoroscopy or navigation.

Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
