"In my experience, the Allen frame performs comparably to the standard OSI Jackson table for non-instrumented cases, with some additional benefits: It's smaller, can be adapted to a regular table, folded into a neat unit for storage and is considerably less expensive."

Allen® Spine


Allen develops technologically advanced patient positioning systems that enhance surgical access. The Allen® Spine System turns any OR table into a surgical spine system. It enables intraoperative flexing of the lumbar spine from kyphosis to lordosis. The prone patient supports are optimized for effective pressure management and adjustability during long procedures.

Allen® Bow® Frame is used to perform simple spine surgeries. The Bow Frame is more versatile than the existing Wilson™ Frame, as the single device attaches to standard OR tables, the Jackson™ Table, and the Allen® Flex Frame. It also has a higher patient weight capacity than the Wilson Frame, of 500 lbs. (227 kg.)
