Negative Bicortical Pins have had a bad reputation for early failure at the thread pin junction. Where selection of pin and frame are appropriate failure of negative threaded pins is rare. The important criterion is thread diameter not shaft diameter. For any given thread diameter both positive and negative threaded pins are equally strong. Virtually all human pins are negative threaded!
Use of Self Tapping Screws can save considerable time and trauma. Pull out strength is not affected provided the self tapping flutes lie outside of the cortex. Self Tapping Screws are less effective in dense cortical bone. e.g. calcaneus. It is advised that an appropriate tap be available should the need arise. Drill data: Pilot Drill 1.1mm, Clearance Drill 1.5mm.
PFTE osteotome handle which accepts a good range of blades plus a diamond rasp (not included in set). Blades are very thin (1.1mm) allowing fine cuts and reducing the incidence of braking the block during block sulcoplasty procedures. Replacement T wrench and retaining screw are also available.
An alternative to the traditional forked plates. Secured using 2.4mm screws in the tibial crest, after the osteotomy and advancement have been made. Distal screws are secured using screws as appropriate. The rest of the technique is as per standard TTA.
Self tapping flutes at the tip obviate the need for pre-tapping which saves time and reduces time related complications. Pull out strength is not affected provided the self-tapping flutes lie outside the bone cortex. Drill data: Pilot Drill 1.5mm, Clearance Drill 2.0mm.
Available either as a standard strip of round holes or as a version with notches between the holes for easy contouring. Plates are available in 1.0, 1.5, 2.0, 2.4, 2.7 and 3.5mm. Hole spacing is smaller than the equivalent DCP which may be useful where bone fragments are small.
This type of Screw is becoming increasingly popular in both human and veterinary orthopaedics. Self tapping flutes at the tip obviate the need for pre-tapping which saves time and reduces time related complications. Pull out strength is not affected provided the self tapping flutes are positioned outside the cortex.
The SUB is a unique system designed for use in dogs and cats. Components of the device are a locking loop pigtail catheter that is placed in the renal pelvis, a fenestrated and cuffed bladder catheter, and a titanium Shunting Port which is positioned subcutaneously. This allows sampling and flushing to be carried out percutaneously.
