Use of a Pediatric Craniotome Drill for Cervical and Thoracic Spine Decompression: Safety and Efficacy.

BACKGROUND: Laminectomy, using a high-speed drill with an unprotected cutting drill bit, can be rapid and effective, but it has been associated with known complications. Another technique uses a pediatric craniotome drill with the footplate attachment. At present, there are no studies comparing clinical outcomes between these 2 stated decompressive techniques.

METHODS: A retrospective review was conducted at a single institution. Two cohorts of patients were considered based on the technical method of laminectomy for decompression. One group had decompression with utilization of a high-speed drill, whereas the other group had decompression with a pediatric craniotome drill with a footplate attachment. The outcomes from each group were compared based on the length of operation, estimated blood loss, and associated complications.

RESULTS: A total of 91 patients were included in the final analysis. Forty-five of the patients underwent laminectomy using a footplate and 46, using a high-speed drill. The footplate group was associated with significantly shorter operative time (159 vs. 205 minutes; P = 0.008). In addition, the footplate technique demonstrated less estimated blood loss (254 vs. 349 mL), and less incidence of durotomies (2.2% vs. 10.9%); however, neither of these 2 outcomes achieved statistical significance.

CONCLUSIONS: Despite being an older technique, there was a shorter operative time in the footplate group without increased blood loss or incidence of durotomy. Although comparable results are operator dependent, this technique is a safe alternative for performing cervical and thoracic laminectomies.
