FEATURING THE FIRST TO MARKET
AP Positioning
Technology
MAVEN™ Patient Specific Guides and Surgical Planning Case Reports were developed to:
- Simplify and expedite alignment
- Accurately determine both implant size selection and placement critical for long-term survivorship1
MAVEN™ Alignment Blocks Features

AP Spacer Guide
Talar PSI Guide
The Maven™ PSI System…
Provides an accurate and simple-to-use technology in the palm of your hand. The Patient-Specific Guides, Surgical Planning Case Reports and Bone Models are based on individual patient anatomic structures, are generated using segments of the patient’s operative limb CT scan and are intended to contour to the patient’s anatomy.
The MAVEN™ PSI System utilizes computer assisted processing technology to achieve accurate tibiotalar alignment and implant placement to reduce potential for eccentric loads,weardebrisandosteolysis.1,2 The System was also designed to address abnormal varus or valgus alignment of the implant construct, reported to be a major cause of implant loosening3 and decreased postoperative function.4
Maven™ PSI System Guides…
- Utilizes an advanced CT based coordinate system designed for precise component alignment, accurate implant placement and size selection critical for long term survivorship5
- Are designed based on individual patient anatomic structures to ensure the Guides contour to the patient’s bone geometry not osteophytes
- Preserves periosteum and anterior talar cartilage during joint preparation due to minimal Guide/bone contact interface
- Provides secure and stable tactile feedback during initial positioning
- Are designed to preserve anatomic landmark references
- Allows for precise component positioning and establishes clearly defined bone resection planes
- The AP Positioning Spacer establishes optimal AP bone coverage
Patient-Specific Technology Based on Research
ALIGNMENT. ORIENTATION. POSITIONING.
The MAVEN PSI System utilizes surgeon inputs and computer assisted processing technology to achieve accurate tibiotalar alignment and implant placement to reduce potential for eccentric loads, wear debris and osteolysis.2, 3
Minimal Joint
Preparation Required
- Are generated based on surgeon inputs and segments of the patient’s
CT scanned anatomy - Address all 6 degrees of rotational and translational orientation
- Allow for enhanced pre-operative visualization of anatomic structures,
bone resection levels and help to identify anatomic abnormalities - Depict APEX 3D™ System Tibia & Talus Implant sizes in simulated implantation
- Surgeon’s input throughout the design process
