Now that extensive facetectomy and total laminectomy for spinal stenosis are generally discouraged, interest in performing foraminotomies as an alternative procedure has grown. Reaching the underside of the foramen is a daunting challenge with a standard, straight-shaft Kerrison-style punch. Curving the shaft allows convenient access to this difficult-to-reach area without having to pass through the treacherous epidural space or navigate around the interspinous ligament. The first curved shaft rongeurs appearing in the early 1980's featured right-angled footplates and relied upon awkward, vulnerable and expensive multiple linkages to navigate the upward curve.
The foramen could be reached, but surgeons complained of difficulty in obtaining a satisfactory bite. Robert A. Beatty, M.D. suggested modifying this rongeur by angling the footplate forward, thereby enhancing its bone grasping ability. The introduction of Buxton's Foraminotomy Punch included an innovative, flattened upper shaft. This feature gave flexibility to this segment, enabling it to better negotiate the curve imposed upon it by the lower shaft. As a result, it reduced the bulk and visual obstruction at the tight and critical working end.
Proud of an innovation as simple and as strong as it is both safe and cost effective, we offer these fine instruments in the most popular bite sizes or as a comprehensive set of three.
The growing popularity of surgery through a tube induced the logical union. An offset shaft moves the obtrusive hand out of the line of vision while our newly introduced shallow curve assures the instrument’s easy passage through the restrictive cannula. Select from among three up bite sizes (2 mm, 3 mm and 4 mm) and two, beyond-the-bayonet shaft lengths of 150 mm and 180 mm.
Both classic Beatty and Bayonet-Beatty Kerrisons are also available in Take-A-Part versions and/or with ceramic finish.
