Features and Benefits
MAXFRAME AUTOSTRUT™ Multi-Axial Correction System provides a solution to the drawbacks of hexapod external ring–fixation treatment by automating the strut-adjustment process and enabling smaller, more-frequent adjustments (up to 20 times per day vs. 1-2 times per day compared to manually adjusting struts).2,3,*,†
Fully automated struts2,3
Eliminates the need for patients to adjust their own struts4 ‡
Helps deliver a better patient experience and may reduce risk of negative clinical outcomes caused by unintended strut adjustment errors5,6
*Clinical outcomes in these cases may not be representative of outcomes in other patients.
†Preclinical studies may not be indicative of clinical performance.
‡Compared to MAXFRAME™ Manual Struts.
Smaller, more frequent strut adjustments1
May be better for surrounding soft tissue, reduce pain, and improve the quality of the bone regenerate vs. larger and less frequent adjustments.2,3,7,*,†
*Clinical outcomes in these cases may not be representative of outcomes in other patients.
†Preclinical studies may not be indicative of clinical performance.
Automate the movement with MAXFRAME AUTOSTRUT Software1
Utilize the MAXFRAME AUTOSTRUT Software to upload the strut adjustment plan to the MAXFRAME AUTOSTRUT Control System.
The MAXFRAME AUTOSTRUT™ Control Box and software place strut adjustment in the surgeon's control which increases adherence to the treatment plan.8
Addressing Challenges

Clinical Challenges of Manual Strut Adjustment
External ring-fixation patients can be highly complex to manage and can have significant burden and cost associated with their journey. Patients and caregivers may struggle with manually adjusting the struts on their external ring–fixation frames. Errors in adherence to the daily strut adjustment treatment plan can lead to more follow-up visits, x-rays, calls to the office, non-unions, re-operations, and patient dissatisfaction.2,*

Improving the Patient Experience
The MAXFRAME AUTOSTRUT Control System can be programmed to operate only during selected hours, enhancing patient convenience.1 Lights and sounds communicate system status to help enhance patient confidence1 and patients have the option to shower/bathe with the MAXFRAME AUTOSTRUT System because the system carries an IP68 water ingress protection rating4.
