- Sliding Hip Screw: (for basilar neck fractures)
- Sliding Screw Insertion Technique
- surgeons will often elect to insert a sliding hip screw along with a single cannulated screw;
- motivation for the addition of a cannulated screw is to prevent rotation of the proximal fragment;
- problem w/ this type of fixation is that the cannulated screw will prevent fracture impaction and may lead to fracture non union;
- in the following example, the reduction is not optimal and the cannulated screw may prevent further fracture impaction;
- may be indicated for some patients w/ basilar neck fractures, but often it is not the surgeon's first choice due to the risk of joint sepsis;
- non union (20-25%)
- avasulcar necrosis (25%);
- Case Example:
- 45-year-old female w/ osteomalacia due to Sheenan's syndrome sustained a femoral neck fracture which was treated w/ a compression hip screw;
- once the patient progressed w/ weight bearing, the hardware cut out superiorly and the fracture went on to non union;
- 70 year old demented male w/ comminuted basilar neck frx. The frx was most stable in retroversion, and therefore a "stable" malreduction was accepted (w/ no apparent failure)
