Purpose

Proximal junctional kyphosis (PJK) is a common post-operative radiographic finding after surgery for adult spinal deformity (ASD) patients. Although the clinical relevance of isolated PJK is unclear, PJK can progress to symptomatic proximal junctional failures which requires a large revision surgery. Currently, post-operative bracing with a thoracolumbosacral orthosis (TLSO) is common practice after spinal deformity surgery, however the efficacy of this in preventing PJK is unknown. This multi-center randomized control trial identified 84 patients undergoing thoracolumbosacral fusion for ASD and plans to study the efficacy of a novel post-operative TLSO in preventing the development of PJK as defined by the proximal junctional angle on 6-month post-operative X-rays.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Thoracolumosacral Orthosis
Patients randomized to this arm will be fitted with an Aspen Medical Products "Align PJK™" TLSO brace. This is a 3-point, rigid hyperextension TLSO brace which is currently FDA approved under a 510k exemption but not commercially available. With this brace, the sternal pad height/width and belt component will be adjusted to optimize patient position and comfort. The brace will also be fitted with an external temperature sensing probe. Patients will be instructed to wear the brace at all times, including when in bed for 6-weeks post-operatively. At the 6-week visit patients will be asked to self-report compliance with the brace
  • Device: Align PJK™ TLSO brace
    Patients will get randomized to receiving and wearing a back brace for 6 weeks postoperatively.
Placebo Comparator
No brace
Patients in the control arm will be treated without a brace but will have no other differences in their post-operative treatment protocol. This will be considered "usual care" for the purposes of this study.
  • Other: Standard of Care
    Patients will receive the standard of care postoperative instructions without a brace
