Developmental dysplasia of the hip (DDH) has been recognized to be a condition leading to osteoarthritis. Periacetabular osteotomy (PAO) has showed good results on hip preservation treatment for these cases. Nevertheless, intra-articular damage may be responsible for persistent post-operative symptoms, so treat the articular damage before or during the PAO has emerged as an alternative to address it. The objective is to identify the prevalence of intra-articular damage, functional outcomes of patients undergoing PAO with untreated intra-articular lesions and the survivorship free total hip arthroplasty (THA) at long-term follow-up. A retrospective review of 103 hips in 92 patients, mean age 26 years old (19–31), 96% females. Mean follow-up 7 years (range: 3–16). Intra-articular damage was evaluated with high-resolution magnetic resonance imaging (MRI) previous to perform the PAO, the chondral damage was evaluated using International Cartilage Repair Society classification. Harris Hip Score (HHS) was obtained in all patients. One hundred per cent of the cases had labral tears on MRI, hypertrophic labrum in 80.8% and paralabral cysts in 20.8%. Acetabular chondral damage was Grade 2 in 88.5% of the hips. HHS was good and excellent in 94%. Survivorship free of THA at 15 years was 87%. Chondrolabral damage is a common finding in patients with DDH. Despite that, excellent results are obtained with PAO without labral repair. We think the focus should be in the biomechanical and anatomical correction of the hip in patients with DDH.
Resumen: El presente artículo reflexiona sobre la nueva modalidad de enseñanza en bioética utilizando una plataforma de aprendizaje virtual. Se señalan las ventajas y dificultades de este nuevo modelo y los desafíos para que sea más efectivo en sus objetivos pedagógicos. Se recomienda el uso de modelos de aprendizaje semipresenciales o de combinación mixta presencial y no presencial en la utilización de la enseñanza virtual en bioética.

BIOETHICS' VIRTUAL TEACHING. CHALLENGESAbstract: The present paper reflects about the new bioethics teaching modality that employs a platform of virtual teaching. It points out this model's advantages and difficulties and the challenges it faces in order to reach an effective result of its pedagogical aims. It recommends to employ semipresential learning models or the combination of a mixed bioethics' virtual teaching: presential and non presential.
