Mini Incision Dynamic Hip Screw Technique (MIDHST)

Intervention / Treatment
Detailed Description
This technique is the same of AO Dynamic Hip Screw (DHS) technique using 4 holes plate or smaller, in this case it is enough to make just a 3 cm skin incision over the guide wire that is inserted parallel to the anteversion wire by using the 135° guide fixed on the T-handle; (step 2-2), and continuing AO technique steps, until step 3-4, for the plate assembling we remove the guide wire, and insert the plate sliding it through the skin cut over the femur shaft under the muscles using the plate for dissection the soft tissue above the bone surface non using any tool as periosteal elevator but the plate itself by holding it from its DHS screw canal and in 180 degree rotation position in axial aspect (transvers aspect) using the plate end for soft tissue gentle dissection over the bone, then turning the plate 180 degree over the bone shaft to the right position and sliding the DHS screw plat canal over the DHS screw using the measuring bar. Two skin stitches are enough.
Technique
Step 1-reduction
In many cases the traction table is used. The reduction is done on this table and before the patient is draped. Important also is to guarantee smooth access of the image intensifier in both planes; AP and lateral.
Step 2-guide wire insertion
- The anteversion of the femoral neck is determined with a long K-wire inserted with the blunt end first. An alternative is to use a long, non-threaded K-wire.
- Under X-ray control, the guide wire is inserted parallel to the anteversion wire by using the 135° guide fixed on the T-handle.
Step 3-screw insertion
- The length of the screw must be measured/determined with the guide wire. Note that the screw must be 10 mm shorter than the length of the guide wire. The surgeon will deduct 10 mm of the measured length to determine the screw length.
- Set the triple reamer to 10 mm shorter than the measured length. The hole is drilled over the guide wire.
- Tapping is only required in young patients with dense bone.
For the plate assembling we remove the guide wire, and insert the plate sliding it through the skin cut over the femur shaft under the muscles using the plate for dissection the soft tissue above the bone surface non using any tool as periosteal elevator but the plate itself by holding it from its DHS screw canal and in 180 degree rotation position in axial aspect (transvers aspect) using the plate end for soft tissue gentle dissection over the bone, then turning the plate 180 degree over the bone shaft to the right position.
- The plate is slid over the wrench.
- The DHS screw is attached to the coupling wrench.
- The sleeve is assembled over the wrench.
Step 4-plate fixation
Impact the plate in order to have best contact with the femur. The plate is fixed with conventional 4.5 mm screws:
- Drill bit 3.2 mm with sleeve
- Measuring
- Tap (when no self-tapping screws are used)
- Insertion of screw
