    Tratamiento de la hiperpresión ósea de la rótula mediante perforaciones óseas: estudio experimental
    (2007) Almeida Parra, F.; Gomar Sancho, Francisco; Sala Cuartero, Diego
    Increased intra-osseous pressure has been postu- lated as one of the causes of patello-femoral pain, and there- fore, decompression osseous drilling has been suggested as a treatment option. With the object of evaluating the efficacy of osseous decompression, we have performed an experi- mental study in sheep. We used twelve sheep from the meri- no race divided into two groups, all with an average weight of 60 kilograms and an average age of 4 years. Group A was de- signed to prove that patellar decompression produces a de- crease in patellar pressures. Therefore, both patellae were traumatised in a controlled manner and the left patella was decompressed, leaving the right patella as the control group. Group B was designed to observe the effects of patellar de- compression alone, in absence of hypertension through pre- vious trauma, the left being decompressed and the right being the control group. In both groups, pressure measurements of pressure were conducted at the beginning of the study, six weeks previous and after accomplishment of the decompres- sion. At 4 months, a histopathological study of both patellae was conducted. Following the statistical analysis of the pres- sure readings at the different time intervals, we conclude that osseous drilling does not decrease the pressure readings, re- gardless of the existence of a state of patellar hypertension. From the histopathological point of view, drilling does not slow or revert the histological degenerative changes, and lastly, the technique to measure the intraosseus pressure can itself constitute an aggression that can ultimately cause de- generative changes.

    Fracturas complejas del radio distal: tratamiento quirúrgico de las fracturas tipo C2
    (2007) Arenas Planelles, Antonio; Ortega Arruti, J.A.; Corchuelo Maíllo, C.; Arenas Miquélez, A.; Ortega Sáez, M.
    Se presentan 73 casos de fractura de radio distal tipo C2 tratadas en nuestro servicio. Se utilizó como método de osteosíntesis una placa palmar en 3 casos, agujas de Kirschner en 38 casos, fijadores externos en 30 y fijador externo + agujas en 2 casos. Los mejores resultados se obtuvieron en los grupos de casos tratados con placa palmar y con agujas + fijador externo. El fijador externo, aplicado de forma aislada, que "a priori" era el mejor sistema de tratamiento, ha resultado al final ser el procedimiento que se ha visto acompañado de una mayor proporción de secuelas clínicas y consolidaciones viciosas.

    Osificaciones heterotópicas tras artroplastia total primaria de rodilla
    (2007) Cabanes, F.; Sangüesa, M. J.
    Introduction. Heterotopic ossification following pri- mary total knee arthroplasty is a poorly studied complication. It was our purpose to study its incidence in our hospital ́s total knee arthroplasties series, and its clinical repercusion. Materials and method. We retrospectively reviewed 798 pri- mary total knee arthroplasties performed between 1.995 and 2.003, 176 heterotopic ossifications (22,05%) being found. We tried to classify the ossifications according to five reported radiographic classification systems, although it was hard to do in an important number of cases. Results. Only seventeen cases had some clinical repercusion, and barely two of them with persistent functional problems needed surgical excision after a one-year maduration, with a good clinical outcome after it. No correlation was found between the different groups in the different classifications and the clinical rele- vance. Conclusion. In this series we found that heterotopic ossifications after primary total knee arthroplasty are relati- vely frequent, most of them without symptomatic repercus- sion. The few cases that needed surgical excision had good outcome.

    El par cerámica-cerámica en la prótesis total de cadera: resultados clínicos a 12 años
    (2007) Villar González, José Luis; Fernández Otero, H.R.; Pérez Cid, C.
    Se analizan retrospectivamente 150 prótesis totales de cadera con par de fricción de cerámica alumínica, con seguimiento clínico y radiográfico a 12 años. se utilizó una prótesis de titanio con recubrimiento de porro mas hidroxiapatita, con superficies articulares de óxido de aluminia en cotilo y cabeza femoral. La edad de los pacientes fue entre 30 y 65 años, con una media de 56. En las revisiones realizadas anualmente se puso de manifiesto una rápida osteintegración de la prótesis y un buen resultado clínico y radiuográfico.

    Rabdomiolisis tras sesión de spinning
    (2007) Fernández Gabarda, Rafael; Sangüesa, M. J.; Cabanes, F.
    Exercise-induced-rhabdomyolysis has been des- cribed usually after exhaustive exercise. Nevertheless it can also occur after moderate exercise in well fit people. The diagnosis is important because its initial control and treat- ment are very important for the patient’s prognosis. We report a clinical case in a young well fit woman after an initial spin- ning class. And with respect to it we review the diagnosis and treatment.

    Artroplastia total de rodilla: clásica o mínimamente invasiva
    (2007) Sánchez Martín, Miguel María
    The MIS has penetrated in the TKA’field same in ot- her areas of our speciality. The aim searchs the faster func- tional patient recovery, practising a lower aggressive treat- ment of the soft tissue around the knee. But, this objective is really obtained today? The author compare results between classic and MIS TKAs through the challenge of the latter one, insisting on the difficulty to give the adequate bone cuts and the correct position to the components across a “mobile win- dow” and a “symbiotic dance”. Another option is the applica- tion of navigators, but at the present time this option does not permit accuracy. Medium and long-term results are lacking and, therefore, is not good to warm up surgeons by compa- nies and more advanced colleagues with this emerging tech- nique without a solid security
