Spinal surgery study reports use of BoneScalpel for osteoplastic laminoplasty

73

A study entitled “Ultrasonic BoneScalpel for osteoplastic laminoplasty in the resection of intradural spinal pathology:  case Series and technical note” has been accepted for publication in Neurosurgery.

According to a Misonix press release, the study was authored by Parker, Kretzer, Recinos, et al and was based on surgeries performed at the Johns Hopkins Hospital, Baltimore, Maryland. 


The press release reported that the objective going into the 40-patient study was to determine the safety and technical feasibility of using the BoneScalpel for osteoplastic laminoplasty, based on the ability of the device to precisely cut bone while preserving the underlying soft tissues and the potential positive impact on post-surgical osteo-integration.  Successful laminoplasty was carried out in all 40 cases with no incidence of spinal instability during the follow-up period. A primary soft tissue complication was reduced by more than 40% versus previously reported institutional rates.


The BoneScalpel, which was used to perform the study, is a novel ultrasonic osteotome (bone cutting device) used for safe, tissue-selective bone dissection that encourages en-bloc bone removal and refined osteotomies while sparing elastic soft tissue structures.  The press release stated that the BoneScalpel has been used extensively for bone removal in the cervical, thoracic and lumbar spine, including deformity surgery.

 
“In clinical studies performed around the world, the BoneScalpel has been shown to result in less bleeding, greater visibility, less bone loss and greater patient safety. We are gratified to continue to receive reports such as this one, which demonstrate impressive clinical results with the Misonix BoneScalpel when used in delicate spinal surgery,” said Michael A. McManus, president and chief executive officer of Misonix.”
