B.Braun BiCONTACT Aesculap Mode D'emploi/Description Technique page 3

The implantation and implantation site are prepared in the following way:
►
Following the femoral head osteotomy and after opening the medullary cavity, prepare the femur with the
BiCONTACT® specific A and B osteoprofilers.
►
Carry out intraoperative orientation of the implant components. When doing this, pay attention to the resection
line and the trochanter wing.
►
Select the implant according to B-osteoprofiler last introduced in the correct position.
►
Before inserting the implants, carry out a test reposition and examine joint mobility, joint stability and leg length.
Bone fractures in the implant bed will affect the anchoring of the implants!
►
Avoid bone fractures by applying careful surgical techniques.
►
Treat bone fractures by appropriate intraoperative and postoperative thera-
pies.
WARNING
►
Observe correct application of the implant components.
►
Do not under any circumstances allow the implant surfaces to be damaged.
►
Make certain the prosthesis shafts and heads are of the same cone size (see cone size printed on implant pack-
aging, e.g. 12/14).
►
Only remove the protective cap from the prosthesis cone immediately before setting the prosthesis head in place.
►
Prior to setting the prosthesis head in place, rinse, clean and dry the exterior cone of the stem, and if necessary,
the inner cone of the prosthesis head.
►
Position prosthesis head with a slight turn under axial pressure and fixate it with a hammer blow using a plastic
(not metal) head punch.
►
Prepare and apply bone cement as described in the user instructions provided by the cement supplier.
►
Follow the instructions for use of Aesculap centralizers.
►
Before closing the wound, ensure, if necessary by means of an image converter, that the implant components are
correctly positioned.
►
To prevent abnormal wear and tear of the prosthesis: Remove any loose bone cement or bone chips before closing
the wound.
When carrying out interventions to replace hip endoprosthesis stems of the type BiCONTACT® Revision, the following
instructions must be observed:
►
Prepare the marrow cavity with A and B reamers if you are going to remove the implant through a proximal
access (if necessary with an additional bone window). Pay attention to the reamer marking and size according
to the planned prosthesis size and length.
►
When preparing the marrow cavity, work the reamers manually, taking care to remove as little bone substance
as possible. If necessary, finish the marrow cavity preparation with B-osteoprofilers and conclude by implanting
a BiCONTACT® revision stem.
►
If the primary stability (axial fit and rotation), carry out distal locking. Use special aiming or/and image amplifi-
cation device for this purpose.
►
Use Aesculap 5-mm locking screws for this step. Observe the instructions for use of the locking screws.
Transfemoral access:
►
When operating through a transfemoral access, lock the BiCONTACT® revision stem.
►
Use A-reamers to prepare the distal fitting of the prosthesis. When doing this, keep to a distal anchoring length
of at least 100 mm.
Risk of locking screw breakage due to permanent distal force transmission!
►
Remove the locking screws after 1 to 2 years (reference period), depending on
bone remodeling and integration of the revision implant in the proximal bone
fraction. The appropriate timing of this intervention depends on the individual
WARNING
patient's situation; it can be later in cases of delayed bone remodeling.
Note
The BiCONTACT® revision stems are locked for the primary stabilization of the prosthesis stem in cases of severe bone
defects. The distal force transmission via the locking screws is designed to be a device for temporary stabilization.
