Fig 1ac: a) 3.5 mm LC-DCP regular; b) 3.5 mm LC-DCP broad; c) 3.5 mm LCP.

The 3.5 mm LC-DCP regular and broad as well as the 3.5 mm LCP are indicated for the treatment of long bone and metaphyseal fractures.

The 3.5 mm LCP has the standard locked plate design with two changes to allow the plate to be placed as close to the joint as possible: The toenail design was eliminated at one end of the plate and the most distal hole changed from a combination hole to a stacked combination hole. The 3.5 mm LCP will be available in lengths of 222 holes.

The 3.5 mm LC-DCP and 3.5 mm broad LC-DCP have a toenail on one end, and a rounded end at the other end. The most distal hole was changed from a DCU hole to a rounded hole. The 3.5 mm LC-DCP comes in lengths of 220 holes and the 3.5 mm broad LC-DCP in 722 holes. All plates are made of 316L stainless steel and fit in the small fragment plate set graphic case.

A 4-year-old Gordon setter suffered a road traffic accident and sustained multiple pelvic fractures.

(Case provided by Michael Kowaleski, North Grafton, USA)

A 7-hole 3.5 mm LC-DCP was applied and two screws were inserted into the sacral body to improve fixation strength in the cranial ilial segment. This bone is quite thin thus note that the screws #1 and #2 are quite short, screws #3 and #4 are the sacral screws and are much longer; the fracture is between screws #4 and #5 (see figure 4a-b)). The opacity on midline in the x-rays is a urinary catheter.
