What is Clinical and radiological results after revision THA with distal locking stem: A cohort study of 44 patients about?

## 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. ## Material and methods: A single-center retrospective observational study included all patients who underwent tha revision with distal locking stem between april 2013 and january 2015 in our university hospital. the implant was a curved distal-locking stem fully coated in grit-blasted titanium alloy and hydroxyapatite (ha) with a collar made of tialv. this concept is based on primary distal fixation by interlocking screws. the primary endpoint was surgical revision for implant exchange. ## Results: A total of 47 procedures with distal locking stem were performed, 44 of which were included. minimum follow-up was 5 years. etiologies of revision comprised 25 femoral loosenings, 13 periprosthetic fractures, 3 infections, and 3 modular taper breakages. six patients underwent re-revisio
