90 & 100 Toddler Osteotomy Plates
The toddler angled blade plate was one of the first products to result from the formation of the Paediatric Expert Group. The original inventory of blade plates for children included an infant plate with a T profile of 2 x 8mm, blade lengths of 26 and 32mm and a side plate based on a one third tubular plate. This is suitable for infant work when protected by a hip spica (such as in DDH). The next plate was the child plate, which had a T profile of 4.5 x 11mm, suitable lengths, but was based on a side plate that took 4.5 screws. This plate is too bulky for slim children with cerebral palsy who have narrow femora, and fractures through screw holes were seen.
The Toddler plate fills the gap. The T profile is 3 x 11mm, lengths 26, 32, 38mm, offsets of 4 and 8mm, and a side plate based on a 3.5mm DCP taking 3.5mm screws. Originally available as a 90 degree plate only, it is now also available in a 100 degree version to allow placement in the centre of the femoral neck in children with severe CP.
90 Toddler Osteotomy Plate
The 90 Toddler Osteotomy Plate 4 mm displacement with 38 mm blade length offers pediatric surgeons greater flexibility when performing intertrochanteric femoral osteotomies. The design of this Angled Blade Plate is identical to the existing 8 mm displacement with 38 mm blade length. The technique for insertion is the same.
