Self-Locking Wrench II: What Is It?

A specialized orthopedic clamping tool for securing implants.
Available in 145mm (for deep – seated operations) and 120mm (for precision work), it uses a self – ratcheting mechanism to lock onto screws, plates, or rods. It is essential for trauma, spinal, and joint replacement surgeries, combining control and efficiency.

Applications of Self-Locking Wrench II

Fracture Fixation
- The 145mm size is used for fixing long – bone fractures (such as the tibia), while the 120mm size is for small – bone fractures (such as phalanges).
Spinal Procedures
- The 145mm wrench locks pedicle screws/rods during spinal fusion, maintaining alignment in the spinal canal.
Joint Replacement
- It holds prosthetic components (like hip or knee implants) in place during positioning, ensuring accurate placement.
Trauma Repair
- Temporarily fixes comminuted bone fragments: the 145mm for large bones and the 120mm for wrists/ankles, facilitating rapid reduction.
Pediatric Orthopedics
- The compact 120mm size is suitable for pediatric fractures (such as forearm fractures), minimizing tissue trauma.
