intrapelvic migration of dynamic hip screw postoperatively leading to total hip arthroplasty: a case report

Background: this study aimed to present a rare case of a failed dynamic hip screw (dhs) used for fixation of intertrochanteric fracture sliding into the pelvis and to review the most common causes of dhs failure in order to prevent this from happening in the future. case report: a 68-year-old woman was referred to the orthopedics clinic with left hip pain and limping from 6 months ago. in our evaluation, she had dhs failure and intrapelvic protrusion. conclusion: there have been several aspects of the previously described dhs failure. we performed a two-stage total hip arthroplasty (tha) for the patient with a good one-year follow-up in the present case.
