[Computer-assisted drilling of the lower extremity. Technique and indications]

Area of Science:

• Orthopedic Surgery
• Medical Technology
• Surgical Navigation

Background:

• Computer-assisted navigation surgery presents challenges and requires careful consideration of indications.
• The use of these techniques should not increase morbidity and must improve upon existing methods.

Purpose of the Study:

• To evaluate the efficacy of a non-invasive fixation method (FISCOFIX-Cast) for computer-assisted surgery.
• To assess the precision of localizing, registering, and treating lesions between the ankle and knee joints.

Main Methods:

• Utilized a non-invasive fixation method (FISCOFIX-Cast) for computer-assisted surgical navigation.
• Employed percutaneous retrograde drilling for lesion treatment, particularly for posterior talus and complex knee joint cases.

Main Results:

• Achieved precise localization, registration, and treatment of lesions between the ankle and knee joints.
• Percutaneous retrograde drilling successfully spared joint cartilage in all treated cases.
• Demonstrated the method's utility in complex knee joint situations requiring precise drilling.

Conclusions:

• The FISCOFIX-Cast method offers a precise and effective approach for computer-assisted treatment of ankle and knee joint lesions.
• This technique is particularly beneficial for accessing difficult-to-reach posterior talus lesions and complex knee joint pathologies.
• The non-invasive nature and cartilage-sparing drilling contribute to improved surgical outcomes in challenging orthopedic cases.
