Best choice of three-dimensional printing-assisted pedicle subtraction osteotomy for the treatment of kyphosis deformity

Abstract

Abstract:

BACKGROUND: Three-dimensional (3D) printing for preoperative planning has been gaining popularity at present. 3D printing has been frequently used in bone tumor resection and pelvic fracture surgery, but seldom used in kyphosis deformity.

OBJECTIVE: To evaluate the clinical effect of 3D printing-assisted pedicle subtraction osteotomy for the treatment of kyphosis deformity.

METHODS: Data of 40 patients with kyphosis deformity from June 2014 to June 2015 were retrospectively analyzed. All patients were randomly assigned to two groups. Patients in the 3D printing group underwent 3D printing-assisted pedicle subtraction osteotomy. Patients in the control group underwent pedicle vertebral osteotomy.

RESULTS AND CONCLUSION: Operation time, blood loss and radiation exposure time were significantly lower in the 3D printing group than in the control group, but correction rate was obviously higher in the 3D printing group than in the control group. Visual analog scale scores and Oswestry disability index in both groups were lower after surgery compared with that before surgery. These findings suggested that 3D printing-assisted pedicle subtraction osteotomy is feasible for treatment of spinal kyphosis. The orthopedic effect is good. It can reduce the operation time and blood loss.
