Technical Aspects on the Use of Ultrasonic Bone Shaver in Spine Surgery: Experience in 307 Patients

Abstract EN

Aim.

We discuss technical points, the safety, and efficacy of ultrasonic bone shaver in various spinal surgeries within our own series.

Methods.

Between June 2010 and January 2014, 307 patients with various spinal diseases were operated on with the use of an ultrasonic bone curette with microhook shaver (UBShaver).

Patients’ data were recorded and analyzed retrospectively.

The technique for the use of the device is described for each spine surgery procedure.

Results.

Among the 307 patients, 33 (10.7%) cases had cervical disorder, 17 (5.5%) thoracic disorder, 3 (0.9%) foramen magnum disorder, and 254 (82.7%) lumbar disorders.

Various surgical techniques were performed either assisted or alone by UBShaver.

The duration of the operations and the need for blood replacement were relatively low.

The one-year follow-up with Neck Disability Index (NDI) and Oswestry Disability Index (ODI) scores were improved.

We had 5 cases of dural tears (1.6%) in patients with lumbar spinal disease.

No neurological deficit was found in any patients.

Conclusion.

We recommend this device as an assistant tool in various spine surgeries and as a primary tool in foraminotomies.

It is a safe device in spine surgery with very low complication rate.
