CORAIL Dysplasia Size 6
Key Surgical Steps
The key surgical steps above are highlights only and may not be used for training purposes. For the detailed procedure, please refer to the CORAIL Portfolio Brochure (9066-35-025) pages 21-23.
- This stem is contraindicated with hemiarthroplasty surgery.
- This stem must not be implanted in patient weighing more than 60kg (130lb).
- All 12/14 heads available in the DePuy Portfolio are compatible with this stem. The maximum offset for the head is limited to 13 mm.
X-ray templates are used during the pre-operative planning to define the femoral neck cutting plane, the degree of lateralisation and the positioning of the cup inside the native acetabular cavity.
Femoral Neck Resection
Following exposure of the proximal femur, the first neck cut is made higher than the one planned, in order to remove the femoral head. The second neck cut will depend on the implant chosen during the pre-operative planning. If the implant chosen is the K6S, then the neck cut will be a 45° angle cut. If the implant chosen is the K6A, then the neck cut will be biplanar as identified.
Femoral Compaction Broaching
The femoral cavity is prepared using the single monobloc broach specific to each type of implant.
The chosen broach is inserted firmly down to the level of the cervical cutting plane.
The broach acts as the trial stem and can be connected to the 135° Short Neck trial segment to test the joint stability using the trial heads.
Femoral Component Insertion
Important Note: The protective covers should be left on until the components are ready to be implanted. Before implanting a femoral head, the male taper on the femoral stem should be wiped clean of any blood, bone chips or other foreign materials.
The stem is introduced by hand first and then impacted down to the level of either the hydroxyapatite coating in the case of the KS6 or at the level of the trochanteric bearing in the case of the KA6.
Femoral Head Impaction
A final trial reduction is carried out to confirm joint stability and range of motion.
Important Note: Clean and dry the stem taper carefully to remove any particulate debris.
Place the femoral head onto the taper and lightly tap it using the head impactor. Ensure bearing surfaces are clean and finally reduce the hip.
Note: A DePuy 12/14 ARTICUL/EZE® head must be used.
