Summary
This study introduces a CT-guided robotic system for precise diagnostic joint injections in foot and ankle orthopaedics. The technique proved safe and effective, significantly relieving pain in all patients.
Area of Science:
- Orthopaedic Surgery
- Medical Robotics
- Diagnostic Imaging
Background:
- Diagnostic injections are crucial for foot and ankle assessment.
- Traditional fluoroscopic-guided procedures have limitations in accuracy and safety.
Purpose of the Study:
- To describe a novel CT-guided robotically-assisted infiltration technique for diagnostic injections.
- To evaluate the safety, accuracy, and efficacy of this technique in foot and ankle joints.
Main Methods:
- A CT-guided mechatronically-assisted joint infiltration was performed on 16 patients using an INNOMOTION-assistance device.
- Successful infiltration was confirmed by CT localization of contrast media in the target joint.
- Pre- and post-interventional Visual Analog Scale (VAS) pain scores were assessed.
Main Results:
- All 16 joint injections were technically successful, with contrast media accurately placed in the target joints.
- A significant reduction in pain scores was reported by all 16 patients post-intervention (p<0.01).
Conclusions:
- CT-guided robotically-assisted intervention is an accurate, reliable, and safe method for diagnostic infiltration of midfoot and hindfoot joints.
- This technique offers a viable alternative to fluoroscopic-guided procedures due to its high accuracy and clinical feasibility.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:31Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
