ABSTRACT
The use of short stem designs in total hip arthroplasty is not a new concept, but its popularity has increased as a bone-sparing alternative to traditional stems. This study analyzed the midterm clinical and radiological results of the Taperloc Complete Microplasty stem (Zimmer Biomet® Warsaw, IN, USA). A total of 32 patients (20 men and 12 women) were retrospectively documented and received 40 stems (eight bilateral). The median patient age was 50 years (interquartile range 43-58) at the time of surgery. The median follow-up was 36.5 months (interquartile range 26.75-50.25). Indication for total hip arthroplasty was osteoarthritis (62.5% of patients), avascular necrosis (25%), and developmental dysplasia of the hip (12.5%). The Merle d'Aubigné score improved from a mean 11.5 preoperatively to a mean 17.5 at the latest follow-up. During X-ray assessment, we observed one subsidence of the stem (3 mm) and four cases of varus malalignment without clinical consequences. No cases of osteolysis were reported, and no stems were revised. According to our results, this short tapered stem shows a good early-term outcome. Prospective results and a longer follow-up are needed to assess the long-term survival of this stem fully.

El liquen escleroso es una enfermedad crónica inflamatoria de causa desconocida. En hombres su presentación es infrecuente y se observa más comúnmente en la cuarta década de la vida. Asimismo, las lesiones extragenitales son inusuales y asientan más comúnmente en extremidades y tronco. A continuación, presentamos un paciente de sexo masculino adolescente con diagnóstico de liquen escleroso en dorso
Lichen sclerosus is a chronic inflammatory disease of unknown etiology. Appearance in men is unusual and is most seen at fourth decade of life. Also extragenital lesions are rare and most commonly settle in extremities and trunk. A case of a male adolescent patient with lichen sclerosus in trunk is reported.
