Abstract
The sliding hip screw, sometimes called the dynamic hip screw (DHS) has been a successful method for treating hip fractures. Nevertheless, mechanical complications of this system have been reported from time to time. They are mainly the result of instability of the fracture, bone quality and technical errors occurring during surgery.
We report a case of an intrapelvic protrusion of a sliding screw after a basicervical fracture was treated with a DHS and a 6.5 mm cannulated screw, and its surgical solution using a hybrid total hip arthroplasty. In our case we think the mechanical failure was due mainly to technical errors during surgery.
Despite that, we believe the sliding hip screw is the implant of choice for basicervical fractures. Using an additional K-wire during the technique is sufficient to avoid rotation of the proximal fragment and no additional fixation is necessary.
