In orthopedic trauma surgery, the ultimate challenge has always been stabilizing injured joints while preserving their natural biomechanics. The historical "Gold Standard" of rigid screw fixation is rapidly being superseded by Suspension and Tensioning Systems that allow for physiologic micromotion.
At Orthosyn Medical, our Double Button Lift System represents the pinnacle of this modern approach, offering surgeons a single, reliable solution for two critical anatomical regions: the Acromioclavicular (AC) Joint and the Ankle Syndesmosis.
In Rockwood Type III and higher AC joint separations, the superior displacement of the clavicle severely compromises shoulder girdle stability.
The Role of the Double Button Lift System in the AC Joint: The system effectively acts as an "artificial ligament," replacing the function of the torn Coracoclavicular (CC) ligaments.
Anatomic Reduction: By anchoring between the coracoid process and the clavicle, the adjustable buttons allow the surgeon to pull the clavicle down into its precise anatomical position.
Controlled Flexibility: The shoulder is a complex structure requiring 3D motion. Unlike rigid systems (such as hook plates or screws) that can restrict movement or erode bone, the Double Button system accommodates the natural rotation of the clavicle.
Permanent Solution: Because the implant is biocompatible and low-profile, there is generally no need for a second surgery to remove the hardware, significantly optimizing the patient's rehabilitation journey.
Damage to the syndesmotic ligament complex occurs in approximately 20% of ankle fractures, leading to diastasis (widening) between the tibia and fibula and resultant instability.
The Superiority over Syndesmotic Screws: The traditional "Syndesmotic Screw" creates a rigid fixation that inhibits the natural movement of the fibula, often leading to screw breakage or loosening. Furthermore, screws typically require removal after a few months.
The Double Button Lift System shifts this paradigm:
Physiologic Micromotion: It allows the fibula to undergo necessary physiological rotation and vertical motion relative to the tibia during gait. This is critical for the long-term health of the joint cartilage.
Reduced Risk of Malreduction: The adjustable loop technology allows the surgeon to apply the exact amount of compression needed to seat the fibula correctly in the incisura, reducing the risk of over-tightening.
Earlier Weight Bearing: Due to its high fatigue resistance compared to static screws, the system often permits earlier mobilization and weight-bearing in appropriate cases.
Whether used in the shoulder or the ankle, the Double Button Lift System offers shared advantages that make it an indispensable tool in the operating room:
Adjustable Loop Technology: The surgeon can manually tension the implant after placement. This ensures a "Goldilocks" stabilization—not too loose, not too rigid—customized to the patient's anatomy.
Knotless Technology: Eliminates the need for complex knot tying, shortening surgical time and minimizing the risk of soft tissue irritation from bulky knot stacks.
High Tensile Strength: Constructed from Ultra-High Molecular Weight Polyethylene (UHMWPE) fibers and Titanium buttons, the system withstands forces far exceeding physiological loads.
Whether stabilizing the clavicle in the shoulder or securing the syndesmosis in the ankle, the Double Button Lift System is a modern biomechanical solution that enhances surgical outcomes, reduces complications, and preserves the patient’s natural range of motion.
