Limb deformities can be congenital, developmental or acquired as the result of fracture, infection, arthritis, or tumor. Left uncorrected, these deformities may lead to amputation and could have a potential cost burden of $500,0001 per patient to the healthcare system. External circular fixation products currently on the market require precise X-rays and manual measurements by surgeons, and any inaccuracies can prolong treatment. Patients suffering from limb deformities may require an average of 37 outpatient visits over 12 months,2,3and one in three patients will experience a residual deformity.4
Unlike other computer-assisted external circular fixation systems, the MAXFRAME System's 3D planning software creates accurate patient treatment plans using advanced algorithms, which eliminates the need for manual measurements and requires fewer inputs than any other system on the market. This can potentially lead to a reduction in the number of patient X-rays required, thus reducing procedural complexity, radiation exposure for both the patient and surgeon, and overall costs, while reducing treatment time for the patient.
Patients undergoing treatment with the MAXFRAME System are responsible for adjusting the struts on the device as per their custom treatment plan. These adjustments have been made easier with the system's newly introduced ASSURE-STRUT Technology, wherein each time the patient adjusts the device, there is an audible click as the strut correctly locks into place.
"The MAXFRAME System incorporates three clinically important advantages that help provide great accuracy of correction for the patient and streamline the surgical phase of care," said Dr. J. Spence Reid, M.D., Professor and Chief of Trauma Division, Department of Orthopaedics and Rehabilitation. "The software eliminates significant sources of error inherent in earlier methods by removing the need to determine reference ring mounting parameters, as well as the requirement of ring orthogonality. The system also allows maximum flexibility in the location of strut attachment points on the ring which makes frame application easier, particularly in complex cases, and the ASSURE-STRUT Technology allows the patient to confidently make strut adjustments."
MAXFRAME Patient Care Program
To support patients, DePuy Synthes has developed the MAXFRAME Patient Care Program, which includes a patient app featuring a character named "MAX," and additional online content is available at www.maxframepatients.com. The program helps patients and their caregivers prepare for surgery, manage treatment and share their experiences through social media channels at the end of their treatment journey.
"There is a significant unmet need for treatment options that reduce both the burden to patients with limb deformities as well as surgical complexity," said I.V. Hall, worldwide platform leader, trauma, cmf, biomaterials and veterinary portfolios, DePuy Synthes. "With the launch of the MAXFRAME System, we are building on our long history of innovation, excellence in service and support for surgeons with unique 3D planning software and digital tools that help address these needs and enhance patient and surgeon satisfaction."
The MAXFRAME System is indicated for the following treatments in adults and in both children (3-12) and adolescents (12-21) in which the growth plates have fused or will not be crossed with hardware: fracture fixation (open and closed), pseudoarthrosis of long bones, limb lengthening (epiphyseal or metaphyseal distraction), joint arthrodesis, infected fractures or nonunions, correction of bony or soft tissue deformities, and correction of segmental defects.
