ABSTRACT
Resumen: Ésta es la segunda de dos partes de la Historia y Desarrollo de la Artroplastía de Cadera. En esta parte se hace una revisión histórica del desarrollo de la artroplastía contemporánea de la cadera, dando continuidad a la primera, donde se analizaron los cuatro primeros períodos. Esta quinta etapa corresponde a la revisión de su última etapa que comprende desde 1970 hasta el momento actual. También se hacen comentarios acerca de nuestras actitudes en el presente y la ruta que vislumbramos hacia el futuro.
Abstract: This is the second of two parts of the history and development of hip arthroplasty. In this part, a historical review of the development of contemporary hip alloarthroplasty is made. The purpose of this part is to give continuity to the first one where the first four periods were analyzed. This fifth part corresponds to the revision of its last stage that includes from 1970 to the present time. Comments are also made about our attitudes in the present and the route we envision towards the future.
ABSTRACT
RESUMEN Introducción: la rehabilitación protésica sobre implantes constituye uno de los tratamientos más novedosos aplicados en Granma y en Cuba. Su caracterización contribuye a elevar la calidad del servicio. Objetivo: caracterizar la rehabilitación con implantes dentarios en la Clínica Universitaria de Especialidades Estomatológicas de Bayamo. Método: se realizó un estudio descriptivo-transversal en 144 pacientes que recibieron rehabilitación mediante implantes dentales en la Clínica Universitaria de Especialidades Estomatológicas Manuel Cedeño, de Bayamo, provincia de Granma, durante febrero de 2014 a diciembre de 2017. Resultados: en los pacientes atendidos con implantes predominaron las mujeres, con el 66,67%, y el grupo de edad de 38-47 años (32,64%). Se colocaron mayor cantidad de implantes en el maxilar que en la mandíbula (71,28-28,72%). Los implantes MIS (65,38%) superan en número a los Leader (34,62%). El tipo de tratamiento que más se realizó en el maxilar fue la prótesis unitaria cementada, y en la mandíbula, la prótesis unitaria atornillada. Se logró éxito terapéutico en la mayoría de nuestros pacientes, tanto con la carga inmediata como con la diferida en ambas marcas comerciales. La única complicación en nuestros pacientes radicó en la falla del proceso de osteointegración. Conclusiones: la rehabilitación sobre implantes dentales garantiza el éxito estético y funcional en la mayoría de los pacientes tratados.
ABSTRACT Introduction: dental implants rehabilitation is one of the most novel treatments applied in Granma, Cuba. Its characterization favors service quality. Objective: to characterize dental implants rehabilitation at Clinical Dentistry Academy of Bayamo, Cuba from February 2014 to December 2017. Method: a descriptive and transversal study was carried out, for characterizing dental implants rehabilitation patients, attended at Manuel Cedeño Clinical Dentstry Academy, in Bayamo province, Granma, Cuba, from February 2014 to December 2017. Universe was formed by 144 patients, who attended the stomatological prosthesis consultation within the same period and received dental implants rehabilitation. Results: age group from 38 to 47 (32.64) was the most representative, in which female patients prevailed (66.67%). Implants were placed in the maxilla rather than the mandible up to (71,28-28,72%). The MIS implants (65,38%) outnumbered the Leader (34,62%). Most performed maxilla treatments were the unitary cemented prosthesis and the screwed unitary prosthesis in the jaw. We succeeded in most of our patients, with immediate or delayed loading in both commercial brands. Osseointegration process failure was the only complication. Conclusions: dental implants rehabilitation process, guarantees aesthetic and functional success in most of the patients.
ABSTRACT
Objective Uncemented prothesis has become the preference of first hip arthroplasty, but there is a little study on its application in cemented acetabular revision arthroplasty.This paper aimed to evaluate the clinical effects of uncemented acetabular cup in cemented acetabular prosthesis revision arthroplasty. Methods A retrospective analysis was made on the clinical data of 31 patients(31 hips) who underwent revision arthroplasty using uncemented acetabular prosthesis from January 2012 to March 2015.Har-ris hip score( HSS) was applied to measure the hip function and visual analogue score( VAS) was preformed to assess the pain degree of knee joint preoperatively and postoperatively(3 months, 6 months and 1 year).All the patients were followed up for a mean of 22 months ranging from 3 to 42 months. Result The mean HSS increased from preoperative points (53.19 ±9.12) to postoperative points([77.71 ±5.75]at 3 months,[80.61 ±5.74] at 6 months,[82.94 ±5.80] at 1 year ).The mean VAS score decreased from preoperativepoints (6.23 ±1.23) to postoperative points(0.26 ±0.27).No lossening, infection or deep vein thrombosis were found in the patients′prostheses. Conclusion For patients with PaproskyI-Ⅱ acetabular defects, uncemented acetabular prosthesis has satisfactory short-term clinical results in revision arthroplasty with cemented acetabular prosthesis, however, long-term clinical results remain to be further observed.
