A novel "push-pull" screw technique effectively distracts the subtalar joint during arthroscopic subtalar joint arthrodesis. This method improves surgical access while preserving critical anatomical structures.
Area of Science:
- Orthopedic Surgery
- Arthroscopy Techniques
- Foot and Ankle Surgery
Background:
- Distraction of the subtalar joint for arthroscopy is technically demanding.
- Existing methods may compromise surrounding soft tissues and vascular supply.
Purpose of the Study:
- To introduce and describe a novel "push-pull" screw technique for subtalar joint distraction.
- To evaluate the efficacy of this technique in facilitating arthroscopic subtalar joint arthrodesis.
Main Methods:
- A fully threaded screw is employed to apply a "push" force on the talus.
- Simultaneously, a "pull" force is applied to the calcaneus to achieve joint distraction.
- The technique aims to minimize disruption of ligamentous, capsular, and vascular structures.
Main Results:
- The "push-pull" technique provides effective distraction of the subtalar joint.
- It allows improved surgical access to the joint space.
- The method preserves important ligamentous, capsular, and vascular structures.
Conclusions:
- The "push-pull" screw technique is a powerful and minimally disruptive method for subtalar joint distraction during arthroscopic arthrodesis.
- This technique facilitates surgical access and preserves vital anatomical structures, with the screw also serving as fixation.
