Multicenter Study
Percutaneous posterior cervical fusion with the DTRAX Facet System for single-level radiculopathy: results in 60 patients.
The authors present 1-year results in 60 patients with cervical radiculopathy due to spondylosis and stenosis that was treated with a bilateral percutaneous facet implant. The implant consists of a screw and washer that distracts and immobilizes the cervical facet for root decompression and fusion. Clinical and radiological results are analyzed. ⋯ Results indicate that the DTRAX Facet System is safe and effective for treatment of cervical radiculopathy.

Multicenter Study
A multicenter analysis of factors associated with change in height after adolescent idiopathic scoliosis deformity surgery in 447 patients.
In the surgical management of adolescent idiopathic scoliosis (AIS), patients are often preoperatively informed that they will gain height as a result of their surgery. However, current estimations conflict significantly and do not have any clinical correlation. The authors developed a formula that would predict postoperative gains in height after deformity correction in AIS. ⋯ The authors' results suggest that changes in the coronal plane contribute more significantly to height changes than those in the sagittal plane and approximately 0.39 cm of height gain can be expected for each 10° of coronal curve preoperatively. Unfortunately, a significant fraction of the postoperative height changes cannot be predicted by currently measured parameters.
