The SAMBA™ Screw System features:

  *Technologically advanced hollow titanium bone screw with radial slots
    which promote fusion by allowing osteogenic and osteoconductive material
    to flow into the SI-Joint.
  *Custom instrument set permits guided placement of multiple SAMBA™ Screws
    across the SI-Joint in a time optimized minimally invasive procedure
    resulting in immediate SI joint stabilization with expeditious and
    comfortable post-operative course.
  *SI-Joint fusion is enhanced by a unique precision engineered applicator
    tool which enables delivery through the SAMBA™ Screw pressurized insertion
    of demineralized bone, bone substitutes, or osteogenic material into the

The inventor of the SAMBA™ Screw System, Dr. Asfora commented, “We have
completed thirty SAMBA™ Screw procedures here in Sioux Falls and the results
have been outstanding. Our design team has optimized the surgical protocol to
have fewer steps compared to other techniques. The result is less time in the
OR and faster patient recovery.”

The cannulated design of the SAMBA™ Screw with sharp bone cutting threads, is
based on the Medical Designs Asfora Bullet Cage, a lumbar fusion device which
has been implanted in hundreds of patients. “We have achieved a remarkable 98%
fusion rate with the Bullet Cage stand alone for one or two lumbar levels,”
added Dr. Asfora. “We expect a similar rate of success with the SAMBA™ Screw.”

According to a study by the Center for Spinal Stenosis and Neurologic Care,
low back pain affects more than 90% of adults at some point and is the most
common reason besides colds for primary care visits. Research conducted by the
Department of Orthopedic Surgery at the University of Minnesota showed that up
to 30% of patients presenting with low back pain had sacroiliac joint

Medical Designs, LLC intends to distribute the SAMBA™ Screw System through a
network of independent reps and distributors.
