Synthes 207.722 4.0mm Cannulated Screw Long Thread 22mm

Synthes 4.0mm Cannulated Screw | Long Thread | 22mm Length | 207.722

The Synthes 207.722 is a high-precision internal fixation implant designed for minimally invasive orthopedic procedures. As a 4.0mm cannulated screw, it features a hollow central core that allows it to be accurately placed over a pre-positioned guide wire ($1.25\text{mm}$ or $1.35\text{mm}$). This ensures that the screw follows the exact trajectory required for optimal fragment reduction, reducing surgical time and soft-tissue disruption.

The Long Thread configuration (typically representing approximately one-third to one-half of the screw length) is specifically engineered to provide superior purchase in the far fragment while the smooth proximal shaft allows for a "lag effect," drawing the bone fragments together for maximum interfragmentary compression.

Technical & Clinical Advantages

• Guide-Wire Controlled Precision: The cannulated design allows for "percutaneous" placement. Once the fracture is reduced and the guide wire is confirmed via fluoroscopy, the screw is advanced over the wire, virtually eliminating the risk of misplacement in complex anatomical zones.

• Optimized Lag Effect: The long-thread design ensures that all threads pass completely across the fracture line into the distal fragment. This creates powerful compression between the fragments as the screw head seats against the proximal cortex.

• Self-Drilling & Self-Tapping Tip: The distal tip features specialized cutting flutes that allow the screw to be inserted directly over the guide wire without the mandatory need for pre-drilling or tapping in many cancellous bone applications.

• Reverse Cutting Flutes: Many Synthes 4.0mm cannulated designs include reverse cutting flutes on the screw head to facilitate easier removal during subsequent hardware retrieval procedures.

• 316L Stainless Steel Biocompatibility: Cold-worked for high fatigue strength, the material is biologically inert and designed to withstand the cyclic loads of functional rehabilitation.

Applications

• Foot and Ankle Surgery: Fixation of malleolar fractures, calcaneal fractures, and midfoot arthrodesis.

• Hand and Wrist Surgery: Stabilization of carpal fractures (scaphoid) and small-bone osteotomies.

• Pediatric Orthopedics: Epiphyseal and metaphyseal fracture fixation (e.g., Slipped Capital Femoral Epiphysis or triplane fractures).

• Trauma Surgery: Stabilization of small-bone fragments and avulsion fractures where precise anatomical alignment is critical.
