ABSTRACT

The total hip arthroplasty with short stems to preserve bone is a good choice in young patients that expected future revision surgery, it is also a good choice when we use approaches for minimal invasive surgeries. In this study, we have evaluated, clinically and radiologically, our experience in total hip arthroplasty with the use of short stems and metaphyseal anchorage. In total we have involved 23 patients with a mean age of 50.2 years (range 45 to 69 y/o) at the time of surgery. The median follow-up was greater than five years. There was a slight Varus femoral stem in three cases, one of them in severe varus. The latter presented continuous pain in the lateral aspect of the thigh that increased with time, with a diaphyseal reaction and an increase in radiolucencies around the stem that required revision surgery 12 months postoperative. A longer follow-up is required to analyze the results and confirm the durability of the observed clinical findings. Patients were evaluated radiological and clinically using the scale of Merle d’Aubigné (MD).


Key words: Short stem, saving of bone, hip arthroplasty.
