Clinical and radiological results after revision THA with distal locking stem: A cohort study of 44 patients.

Background: Distal locking stems were developed in response to some complex revision procedures in total hip arthroplasty (THA), providing better axial and rotational stability. The aim of the present study was to assess medium-term clinical and radiological results of treatment with last-generation distal locking stem.

Hypothesis: Our hypothesis was that this implant provided a high survival rate.
