Summary
To reduce postoperative complications due to pelvic canal narrowing following triple pelvic osteotomy, it is important to minimize the length of the pubic remnant on the acetabular segment. Three different techniques for performing the pubic osteotomy were compared: a lateral wire saw technique, a lateral osteotome technique and a ventral osteotome ostectomy technique. The lateral wire saw and ventral ostectomy techniques resulted in significantly shorter pubic remnants than the lateral osteotome technique. The osteotomies performed with the wire saw were more accurate and precise than those performed with the osteotome. The lateral wire saw technique is a practical alternative to the ventral ostectomy technique for performing the pubic osteotomy.
A comparison of three different pubic osteotomy techniques for the triple pelvic osteotomy showed that minimal pubic remnants can be achieved with either the lateral wire saw or ventral ostectomy technique. Osteotomies made by the wire saw were more accurate and precise than those made by the osteotome.
