REVISION CEMENTLESS FEMORAL STEM WITH DISTAL

VEGA Revision Cementless Femoral Stem With Distal Fixation Surgical Techinique - 82.30 Revision Cementless Femoral Stem With Distal Fixation RAW-MATERIAL: TITANIUM (Ti 6Al 4V – ELI) ASTM F 136 SURFACE FiNISHING: Sand blasted Total hip prosthesis history and evolution is very well described in literature and at a first approach the majority of the results may be considered as satisfactory. However, a number of factors may contribute to restrain in a total hip prosthesis duration. Among the several reasons that may lead to ruin an implant, following ones may be pointed out: Aseptic component ruin,...

VEGA Revision Cementless Femoral Stem With Distal Fixation Surgical Techinique - 82.30 Pre-operative Planning: To previously define the diameter and the length of the VEGA Revision Cementless Femoral Stem with Distal Fixation to use is the most important point of the pre-operative planning. The pre-operative planning is more reliable on what refers to determine the stem length to use, and less accurate on a\what refers to the stem diameter, due to the penetration deepness of the longitudinal stem grooves in the bony cortical. Diaphyseal milling cutters used in the medullar channel preparation...

VEGA Revision Cementless Femoral Stem With Distal Fixation Surgical Techinique - 82.30 Check correct placement of guide string with image intensifier. VEGA Revision Cementless Femoral Stem With Distal Fixation may be implanted in the way that may the best please the surgeon. Warning: Remove primary prosthesis from medullar channel as well as cement fragments and other materials that may perturb the appropriate insertion and anchorage of the stem. 3. Channel milling Flexible milling cutter (optional) Mill medullar channel following guide string and with FR.9.ref. flexible milling cutters help...

Greater diameter of flexible milling cutter used shall be 2mm less than the diameter of the definitive stem selected in pre-operative planning. Example: Should a Ø13,0mm stem be selected in pre-operative planning, flexible milling cutter diameter shall not exceed 11,0mm. VEGA Revision Cementless Femoral Stem With Distal Fixation Surgical Techinique - 82.30 4. Channel milling operation. Straight milling cutter Use FR.25.A.Ref. straight milling cutter to final mill medullar channel, use milling cutters progressively until the stem diameter determined in pre-operative planning. Insert the straight...

VEGA Revision Cementless Femoral Stem With Distal Fixation Surgical Techinique - 82.30 Detail of milling cutter insertion level referred to greater trochanter. VEGA prosthesis shall be inserted until impactor mark matches greater trochanter. 5. VEGA prosthesis placement Use IP.78 / IP.78.A prosthesis impactor, to place VEGA prosthesis. Screw impactor in previously defined prosthesis. Assure that impactor is firmly fixed to Prosthesis. This is when VEGA prosthesis is placed in accordance with what established in pre-operative planning. Placed VEGA prosthesis detail.

VEGA Revision Cementless Femoral Stem With Distal Fixation Surgical Techinique - 82.30 After having cleaned cone, femoral head previously selected and tested. Use 8280.A impactor for a final head impactation. Fill existent hollows with either natural or synthetic bony graft. When VEGA prosthesis should have been properly placed, TT.18.Ref. test head is positioned to determine the height of the neck TT.18.22.M/L, TT.18.26.S/M/L/ XL/XXL or TT.18.28.S/M/L/XL test head models may be used. Prosthesis extraction Use EX.22 extractor should a VEGA prosthesis extraction be required.
