Implant Description Surgical Technique ■ Preface The cementless cup of a total hip joint replacement type SF of the 2nd generation was designed using the latest knowledge and experience with cementless endoprostheses. It is made of titanium alloy and manufactured using latest technology by CNC-controlled machines for surfacing. Surface is conditioned with plasma coating of bioactive titanium oxide layer that ensures full biocompatibility of the implant. Instruments ensure easy implantation and thorough fixation. Wide size series available makes it possible to solve almost every case of...

Implant Description Surgical Technique Surgical technique – cup 1. Preparation of the acetabulum Acetabulum is drilled to the dimension determined with aid of a transparent pattern and the pre-operative X-ray. Special acetabular reamers 1 are used clamped into adapter 11 (see Fig. 1). First, use a reamer of the same size as the original acetabulum. Gradually change to larger reamers at 2-mm intervals, until cartilage is completely removed. Hard subchondral bone underneath must be completely exposed. Upon preparing the acetabulum, remove remains of joint’s socket and large osteophytes. 2....

3. Implantation of the acetabular component - cup (Implantation of the socket coat) Firstly, prepare the set for insertion of the implant. The metal coat of non-cemented socket, which must be 2-mm larger in diameter than the largest reamer used, is inserted into the acetabulum 24 , by means of a holder, (see Fig. 3), with a horizontal 25 and vertical 26 shoulders and protractor. Coat is connected with guiding holder by setting oval end of the stem into the bottom of the coat and screwing the guiding holder into the threaded hole in the coat. Tighten connecting hexagonal screw in handle...

Implant Description Surgical Technique A uxiliary fixation with screws – par. 4 and 5 This part applies only if coats with holes are used (type B3, B10 and B12) 4. rilling of holes D If using coats with holes for screws, use a 3.2-mm drill with a flexible extension 30 , (see Fig. 4), and a drilling coat 27 set for the 3.2 hole. Using a special depth gauge 34 , measure the depth of holes – scale of the gauge will show the right length of screws. If a 3-hole coat is used, turn the holes towards the top of the acetabulum to make the fixation. 5. nsertion of screws I For cancellous screw L 20...

7. Insertion of the articulated insert Before final insertion of the polyethylene articulated insert, (see Fig. 7), make sure that the safety wire of metal coat is functioning properly. If the position is correct, insertion of articulated insert will be accompanied by the sound of a click. Check contact of both components with the aid of a small raspator. ■ Instrumentation set Instrumentation set is stored in three trays (order number of set 301020) with the possibility to add additional 2 sets (order numbers: - see page 12, 300020 - see page 14) allowing clear arrangement of instruments...
