Aspen Medical Products Launches First Bracing Solution for PJK

Aspen Medical Products has launched the Align Orthosis. In collaboration with spine surgeon Han Jo Kim, MD of the Hospital for Special Surgery, Align Orthosis is the first prefabricated TLSO designed to help lower the post-surgical occurrence of proximal junctional kyphosis (PJK).
 
“Isolation of a single strategy is yet to be successful in PJK prevention. When used post-operatively, the Align Orthosis is a non-invasive addition to mitigation strategies, so we truly have a multifactorial approach to prevention,” said Dr. Kim.
 
According to a published study in Spine, spine deformity surgeries are increasing, up 141% between 2004 and 2014. Additional research suggests that proximal junctional kyphosis (PJK) occurs in approximately up to 30% of adult deformity surgery patients, with most cases occurring within two years of surgery.
 
The Align Orthosis is an evolution of current hyperextension braces. It offers better flexion control, comfort and patient compliance, helping to reduce readmission and revision surgery rates. This is achieved by a three-point pressure system that contacts key points at the chest, lower abdomen and mid-back. 
 
The design of the brace also helps to restore symmetrical spinal loads and guide patients through correct spinal biomechanics to help patients safely move after surgery and improve balance.
 
“Some of my patients had altered body mechanics, so I thought that using a brace for flexion control would be helpful in teaching them a better way to move their spine after an operation and ultimately reduce the risk of developing PJK,” said Dr. Kim.

This led to a retrospective analysis, comparing outcomes of a cohort of patients that were either braced or non-braced post-surgery. This research showed that post-surgical bracing with a hyperextension brace made a patient three times less likely to develop PJK.¹
 
Despite the positive outcomes of the study, post-operative compliance varied due to flexion control problems and discomfort, such as the brace riding up when patients sat down and irritation at the surgical site.
 
“We thought we could make improvements to the design to make it more patient-friendly, therefore increasing compliance and potentially mitigating the risk for developing PJK,” said Dr. Kim.
 
“The Align Orthosis embodies our commitment to advancing treatment and improving outcomes for spinal deformity patients, made possible through collaboration with spine surgeons,” said Jim Cloar, Aspen’s Chief Executive Officer. “As a leader in spinal care, we are dedicated to supporting surgeons with new strategies to help mitigate the increasing post-surgical PJK incidence rate.”
