Sliding Hip Screw for Fixation of Fracture Through a Previously Arthrodesed Hip.

Hip arthrodesis is a treatment option for painful chronic hip conditions. Hip fractures through a previously arthrodesed hip are relatively uncommon as indications for hip arthrodesis are rare. The following case reports on the use of a sliding hip screw and a pelvic reconstruction plate to address arthrodesed hip fracture in an 81-year-old man. The use of a dynamic hip screw in this setting gave us a stable fixed-angle construct with compression across the fracture site, and the addition of a trochanteric side plate added to the stability. The dynamic compression plate with limited bone contact was used to neutralize the construct. This case describes the successful treatment of such an injury in a way not previously described in the literature with the intent of giving the orthopaedic traumatologist another method to approach this rare injury.
