Procedure of the Month

This is the case of a 68 year-old male suffering from severe back pain for 3 months. Patient failed conservative treatment with high doses of analgesics. MRI was performed, as shown in Figure 1 below. This T2-weighted image clearly revealed evidence of acute fracture with bone marrow edema at the L1 level. Which choice do you think best describes the patient's treatment options (click on the x-ray below to take the multiple choice/guess test)?

Multicenter Clinical Trials: Do They Get the Respect They Deserve?
They’re not fast or sexy, but they are critical…large trials, that is. With multiple sites and principal investigators who donate their time, large trials are more complex—and normally yield more actionable data—than smaller, quicker studies.

Pioneer Surgical Receives Clearance for “No Torque” Pedicle Screw System
By Walter Eisner
April 7, 2008

In 2007, Marquette, Michigan-based Pioneer Surgical acquired the global rights to a pedicle screw system called the LowTop™ from AlpineSpine, LLC.

On the 1st of April, Pioneer announced that this "no torque" locking feature pedicle screw system had received 510(k) clearance from the U.S. Food and Drug Administration.

Company CEO and founder Matthew Songer, M.D., said the product’s design "holds great promise in offering spine surgeons additional flexibility with next-generation technology to treat a broad range of deformities and physical anatomies.”

The LowTop system has a low-profile design, and the "no torque" locking feature offers surgeons a screw system complete with poly axial and fixed screws in a variety of modular and pre-assembled size ranges. The company believes this system will reduce operating room time and improve patient outcomes. It also said that the poly axial screw has the unique ability to be locked in any position prior to the locking of the rod, which allows for compression, distraction and rod rotation prior to the final lock.

Pioneer is best known for its articulating PEEK-on-PEEK technology in its NUBAC™ and cervical motion preservation series. The company's portfolio of vertebral spacers, cervical plating systems, and MIS and Mini-Open Rod systems include trade names such as Contact™, IJAK®, Clarity™, SlimFuse™, and Quantum®.

In addition to acquiring the global rights in 2007 to the LowTop system, the company also entered the orthobiologics market in 2007 with two acquisitions. The first, Encelle™, Inc., developed E-Matrix™ for tissue regeneration. The second, Angstrom™ Medical, Inc., is the first company to obtain FDA approval for a nanotechnology device, the NanOss™, a hydroxyapatite bone void filler.
