HELICA Cementless Hip System

Volker Hach

The HELICA-Endoprosthesis is a newly developed cementless hip prosthesis for dogs. The acetabular cup and the stem are made of a bio-compatible, osteoconductive titanium alloy and have self-cutting threads. Both the femoral stem and acetabular component of the prosthesis are initially screwed into position following bony preparation. Ingrowth of bone into the prosthesis subsequently follows. The prostheses comes in five standard sizes. All different sizes of stems, cups and heads can be combined with each other. The results of more than 70 dogs operated on using the HELICA-Endoprosthesis are very good. Follow-up radiographs were taken 6 weeks, 6 months and 1 year after surgery. The follow-up time is as long as 3,5 years. The main advantage of the HELICA-Endoprosthesis is the relatively easy surgical technique and short surgery time. Also revisions have been less complicated in the few cases in which it was necessary.
