Summary
A novel arthroscopic screwdriver system effectively treats joint instability and fractures. This innovative system, used in 81 cases, demonstrates improved outcomes with an extra-articular technique, reducing complications like screw loosening.
Area of Science:
- Orthopedic Surgery
- Arthroscopy
- Biomedical Engineering
Context:
- Arthroscopic surgery requires specialized instruments for precise screw placement.
- Minimally invasive techniques are increasingly preferred for joint procedures.
- Titanium screws offer biocompatibility and strength for orthopedic fixation.
Purpose:
- To introduce a new arthroscopic screwdriver system for implanting small titanium screws.
- To evaluate the efficacy and safety of this system in various joint injuries.
- To compare intra-articular versus extra-articular screwing techniques for shoulder instability.
Summary:
- A new arthroscopic screwdriver system facilitates the introduction of 2.7 mm (thread diameter) titanium screws, with or without a 5 mm washer.
- The system features a screw-holding device for controlled grasping, release, and removal of screws.
- The system was utilized in 81 cases, including shoulder instability, greater tuberosity fractures, knee intercondylar eminence fractures, and ankle fractures.
Impact:
- The extra-articular screwing technique significantly reduced complications, such as screw loosening, compared to the intra-articular method in shoulder instability cases.
- The system proved effective for arthroscopic refixation of the labrum-capsule complex, greater tuberosity fractures, and other joint injuries.
- This innovation enhances arthroscopic surgical capabilities, offering a minimally invasive solution for complex orthopedic conditions.
