cemented hemiarthroplasty
DESCRIPTION
Surgical technique for cemented hemiarthroplasty by lateral approachTRANSCRIPT
Cemented Hemiarthroplasty1. Patient in Lateral Position2. Incision centering the GT around 7 cm above and below3. Incise fascia lata along the line of incision and extend towards Gluteus Maximus4. Incise Gluteus medius along the line superiorly and curve it anteriorly in the attachment sparing the Vastus lateralis. The posterior to 1/3 of Gluteus medius is left intact5. Slowly externally rotate the hip and subperiosteally elevate the anterior attachment of Gluteus medius and minimus. 6. Incise the capsule along the neck7. Deliver the NOF and Keep the limb in externally rotated and in Figure of 4 position8. Cut the neck at 1 cm proximal to LT. Oblique cut9. Deliver the head using skid or head extractor and measure the head size. Head size is the size just less to the one where it passes freely10. Use Box chisel to chisel out the cancellous bone in the GT. Chisel to be positioned pointing at the direction of neck remnant11. Use rasp to make path for the prosthesis passing it flush with the lateral cortex12. Insert the prosthesis and do a trial reduction.13. Reduction: Traction till the head is at the level of acetabulum. Hold the superior labrum with kocher and then internally rotate.14. Asses the reduction15. Use a bone hook to redislocate16. Check for loose fragments inside the acetabulum17. Insert a bone plug into the canal18. Mix cement19. Put a suction canula inside the medullary cavity and connect to suction device20. Insert cement when it reaches the desired consistency (doesnt stick to gloves)21. Insert the prosthesis and reduce22. Put drain23. Repair the Gluteus medius, Fascia lata, Sub cut and skin
