          Abstract

          Resumen: Introducción : El manejo terapéutico de las fracturas de maléolo posterior en las fracturas trimaleolares de tobillo continúa en debate. Nuestro objetivo fue realizar una búsqueda de la evidencia científica sobre los aspectos terapéuticos de las fracturas de maléolo posterior en el contexto de las fracturas trimaleolares. Materiales y métodos: Se realizó una revisión de la bibliografía sistematizada por dos revisores, centrados en el manejo terapéutico del maléolo posterior. Resultados: Se obtuvieron 16 artículos clínicos de un total de 1029 pacientes, 8 estudios nivel de evidencia II y 8 de nivel IV. Se sistematizaron las indicaciones quirúrgicas y se analizaron los resultados funcionales y las complicaciones. Conclusiones: La comprensión pato-anatómica de estas fracturas es cada día mayor, principalmente por la utilización habitual de tomografías computarizadas (TC). El tratamiento quirúrgico sobre el maléolo posterior está evidenciando buenos y excelentes resultados funcionales. Para una adecuada decisión terapéutica se debería tener en cuenta ciertos factores: inestabilidad tibiotalar y sindesmótica, congruencia articular y características morfológicas del maléolo posterior. La reducción abierta (RA) y fijación interna con placa de sostén es el tratamiento que ha demostrado mejores resultados a corto y mediano plazo, no encontrando estudios con seguimiento a largo plazo.

          Abstract: Introduction: The therapeutic management of posterior malleolus fractures in trimaleolar ankle fractures continues in debate. Our objective was to conduct a search for scientific evidence on the therapeutic aspects of posterior malleolus fractures in the context of trimaleolar fractures. Materials and methods: A review systematic of the literature was carried out by two reviewers, focusing on the therapeutic management of the posterior malleolus. Results: 16 clinical articles were obtained with a total of 1029 patients, 8 studies level of evidence II and 8 studies level IV. The surgical indications were systematized, and the functional results and complications were analyzed. Conclusions: The patho-anatomical understanding of these fractures is increasing every day, mainly due to the usual use of CT scans. Surgical treatment on the posterior malleolus shows good and excellent functional results. For an adequate therapeutic decision certain factors should be taken into account: tibiotalar and syndesmotic instability, joint congruence and morphological characteristics of the posterior malleolus. Open reduction and internal fixation with support plate is the treatment that has shown better results in the short and medium term, not finding studies with long-term follow-up.

          Pathoanatomy of posterior malleolar fractures of the ankle.

          The functional outcome following ankle fractures that involve a posterior malleolar fragment is often not satisfactory, and treatment of this type of fracture remains controversial. Thorough knowledge of the pathologic anatomy of the posterior malleolar fracture is essential for planning appropriate treatment. Thus, we conducted a computed tomographic study to clarify the pathologic anatomy of the posterior malleolar fracture. Between 1999 and 2003, fifty-seven consecutive patients with a unilateral ankle fracture with one or more posterior fragments were managed at our hospital. We reviewed the patients' preoperative computed tomographic scans to determine (1) the ratio of the posterior fragment area to the total cross-sectional area of the tibial plafond and (2) the angle between the bimalleolar axis and the major fracture line of the posterior malleolus. Each fracture was categorized according to the location of the major fracture line on the computed tomographic image at the level of the tibial plafond. The fifty-seven fractures were categorized into three types: (1) the posterolateral-oblique type (thirty-eight fractures; 67%), (2) the medial-extension type (eleven fractures; 19%), and (3) the small-shell type (eight fractures; 14%). Two of the eleven medial-extension fractures extended to the anterior part of the medial malleolus. A total of nine of the eleven medial-extension fractures actually consisted of two fragments [corrected] The conditions are not exclusive of one another; for example, in the case of one of the fractures exhibiting two fragments, the fracture also extended to the anterior part of the medial malleolus [corrected] The average area of the fragment comprised 11.7% of the cross-sectional area of the tibial plafond for posterolateral-oblique fractures and 29.8% for medial-extension fractures. In the cases of seven of the nine fractures that comprised >25% of the tibial plafond, the fracture line extended to the medial malleolus. The angles between the bimalleolar axis and the major fracture line of the posterior malleolus varied. The fracture lines associated with posterior malleolar fractures appear to be highly variable. A large fragment extending to the medial malleolus existed in almost 20% of the posterior malleolar fractures in the current study, and some fragments involved almost the entire medial malleolus. Because of the great variation in fracture configurations, preoperative use of computed tomography may be justified. The information obtained from this study will be helpful for conducting basic research of this condition and for determining appropriate surgical approaches.

            Surgeon practices regarding operative treatment of posterior malleolus fractures.

            Operative indications for surgical treatment of posterior malleolar fractures associated with fractures of the distal fibula and tibia are not currently well defined. The purpose of the present study was to determine the current practice among orthopaedic surgeons regarding the management of posterior malleolus fractures.

              Influence of fragment size and postoperative joint congruency on long-term outcome of posterior malleolar fractures.

              One of the factors contributing to long-term outcome of posterior malleolar fractures is the development of osteoarthritis. Based on biomechanical, cadaveric, and small population studies, fixation of posterior malleolar fracture fragments (PMFFs) is usually performed when fragment size exceeds 25-33%. However, the influence of fragment size on long-term clinical and radiological outcome size remains unclear.
