PURPOSE: Numerous methods for anterior column reconstruction have been described after en bloc resection of spinal tumors. Restricted proof exists relating to one being superior to a different. The aim of this examine is to judge 3D-printed vertebral our bodies for spinal reconstruction after en bloc resection within the thoracolumbar backbone.
METHODS: Potential observational examine on custom-made 3D-printed titanium reconstruction of vertebral our bodies after en bloc resection for spinal tumor was performed between November 2015 and June 2017. 3D-printed vertebral our bodies have been monitored for mechanical problems akin to (1) migration, (2) subsidence into the adjoining vertebral our bodies, and/or (three) breakage. Issues and associated particulars have been recorded.
RESULTS: 13 sufferers (7 females and 6 males) have been enrolled, and reconstruction of the anterior column was carried out utilizing custom-made 3D-printed titanium prosthesis after en bloc resection for spinal tumor (eight major bone tumors and 5 solitary metastases). Subsidence into the adjoining vertebral our bodies occurred in all sufferers at each proximal and distal bone-implant interfaces; nonetheless, it was clinically irrelevant (asymptomatic, and no penalties on posterior instrumentation), in 11 out of 12 sufferers (92%). In 1 affected person (#four), severity of the subsidence led to revision of the assemble. At a mean 10-month follow-up (vary 2-16), 1 implant was eliminated resulting from native recurrence of the illness and 1 was revisioned resulting from progressive distal junctional kyphosis.
CONCLUSION: Preliminary outcomes from this collection recommend that 3D printing could be successfully used to supply custom-made prosthesis for anterior column reconstruction. These slides could be retrieved below Digital Supplementary Materials.
