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.
