ABSTRACT

INTRODUCTION: Ankle fractures are among the most common injuries treated by orthopaedic surgeons. Malunion is one of the possible complications, and corrective surgery is often used to avoid long-term disability. However, few studies address medial malleolus malunion and the best revision surgery technique is controversial. We describe a new surgical technique, the "box resection". MATERIAL AND METHODS: We present two cases of medial malleolus malunion with secondary talus lateral translation and syndesmotic incongruence. In order to restore a congruent tibiotalar joint, we performed the described technique. RESULTS: We record significant improvement of AOFAS Score and range of motion in both cases, with resolution of pain symptoms. Postoperative radiographs show a congruent mortise with syndesmosis reduction. CONCLUSION: The box resection allowed immediate talus medial translation to its original position. It is a simple and effective solution, with a good functional outcome.


INTRODUCCIÓN: La consolidación viciosa del maléolo interno es una posible complicación en las fracturas maleolares. Su tratamiento es difícil y controvertido, por el momento no hay una solución estándar. Proponemos una nueva técnica quirúrgica para el tratamiento de estos casos que denominamos "resección en caja". MATERIAL Y MÉTODOS: Presentamos dos casos de consolidación viciosa del maléolo interno, asociados con traslación lateral del astrágalo y incongruencia de la sindesmosis, donde aplicamos la técnica quirúrgica descrita. RESULTADOS: En ambos casos, obtuvimos una mejora significativa en el puntaje AOFAS y en el rango de movilidad, así como en la resolución de las molestias por dolor. Las radiografías muestran mortajas congruentes y anatómicas, con una reducción satisfactoria de la sindesmosis. CONCLUSIÓN: La técnica de "resección en caja" es simple y eficaz produciendo un buen resultado clínico y funcional.

ABSTRACT

Two antigens comprising either concentrated culture filtrate containing the plasminogen activator, PauA (total antigen) or the same preparation from which PauA had been selectively removed by incubation with a PauA-specific monoclonal antibody and immobilisation on Protein-G agarose (depleted antigen) were combined with either Freund's incomplete adjuvant (FIA) or a commercially used adjuvant (SB62) and used to vaccinate dairy cows by a subcutaneous route. Immunisation of four animals with depleted antigen combined with FIA conferred no protection to mastitis following intramammary challenge with S. uberis 0140J. However, immunisation of two groups of four animals with the total antigen combined with either FIA or SB62 induced protection in 3 out of 8 and 5 out of 8 similarly challenged quarters, respectively. Protection corresponded to the production of an inhibitory antibody response to PauA.
