Universal 2™ total wrist arthroplasty: A single-surgeon 6.5-year follow-up study of 22 prostheses.

Total wrist arthroplasty remains controversial, with the few studies undertaken being heterogeneous and having low patient numbers. This prospective study involved 22 Universal 2™ total wrist prostheses implanted by the same surgeon between 2003 and 2017. There were 13 women and nine men with an average age of 56 (42-69.5) years. Indications for total wrist arthroplasty were post-traumatic arthritis, rheumatoid arthritis and Kienböck's disease. The mean follow-up was 6.5 (3-17) years. Two failed implants required total wrist fusion. Postoperative pain, grip strength, QuickDASH, patient-rated wrist evaluation, and Mayo wrist scores improved significantly compared with preoperative scores. The prosthesis preserved equal or slightly greater range of motion than the preoperative range of motion, sufficient to undertake activities of daily living and improve quality of life. Postoperative radiographs 1 month after the surgery and then annually showed signs of bone deterioration in 64% of implants, most osteolysis without loosening, compatible with asymptomatic function. Although a high number of radiographic signs of implant changes were apparent in the midterm, 91% of prostheses are still in place. The long-term survival of this implant is uncertain. LEVEL OF EVIDENCE: Therapeutic IV.

[Epidemiology, clinical results and success rate in hip preservation surgery in avascular osteonecrosis of the femoral head]. / Epidemiología, resultados clínicos y tasa de éxito en cirugía preservadora de cadera en la necrosis avascular de cabeza femoral.

INTRODUCTION: Avascular osteonecrosis of the femoral head (ONFH) is a frequent pathology with an insidious and asymptomatic presentation in early stages, so the diagnosis is often made in advanced stages, where the only effective solution is total hip arthroplasty (THA). Diagnosis in early stages will allow the use of therapeutic options that avoid or delay ATC. Our objective is to evaluate the demographic, clinical results and the success rate in our center of patients diagnosed with ONFH and who have been subsidiary of hip preservation surgery. MATERIAL AND METHODS: Unicentric, prospective, uncontrolled clinical study of patients diagnosed with ONFH between January 2012 and September 2017 with a Steinberg IIIA stage. The surgical technique used is decompressive forage, associated with bone allograft and bone marrow aspiration. RESULTS: 26 hips were operated on with our surgical technique. The success rate obtained is 61.54%, since 10 cases have required THA during the study (38.46%). CONCLUSIONS: The therapeutic success in ONFH is directly related to the degree of the disease, which is why early diagnosis is important. The decompressive forage with bone allograft that associates bone marrow aspiration is an option to be taken into account, since in early stages it shows a high success rate.

INTRODUCCIÓN: La necrosis avascular de cabeza femoral (NACF) es una patología frecuente que en sus inicios es asintomática y se manifiesta de forma insidiosa, por lo que a menudo el diagnóstico se realiza en estadios avanzados, donde la única solución eficaz es la artroplastía total de cadera (ATC). El diagnóstico en fases precoces permitirá utilizar opciones terapéuticas que eviten o retrasen la ATC. Nuestro objetivo es valorar los resultados demográficos, clínicos y la tasa de éxito en nuestro centro de pacientes con diagnóstico de NACF y que han sido subsidiarios de cirugía de preservación de cadera. MATERIAL Y MÉTODOS: Estudio clínico unicéntrico, prospectivo, no controlado de pacientes con diagnóstico de NACF entre Enero de 2012 y Septiembre de 2017 con un estadio Steinberg IIIA. La técnica quirúrgica utilizada es el forage descompresivo, asociado a relleno con aloinjerto y aspirado de médula ósea. RESULTADOS: Se intervinieron 26 caderas con nuestra técnica quirúrgica. La tasa de éxito obtenida es de 61.54%, ya que 10 casos han precisado ATC durante el estudio (38.46%). CONCLUSIÓN: El éxito terapéutico en la NACF está directamente relacionado con el grado de la enfermedad, por lo que es importante el diagnóstico precoz. El forage descompresivo con relleno de aloinjerto que asocia aspirado de médula ósea es una opción a tener en cuenta, ya que en estadios iniciales muestra una elevada tasa de éxito.

[Unusual evolution of reactive arthritis after endovesical immunotherapy with BCG].

Intravesical instillation of BCG (Bacille Calmette-Guerin) is a therapy prepared with weakened strains of Mycobacterium bovis and is an effective complementary treatment for high-risk (non-musculoinfiltrating or non-invasive) bladder cancer. Although its safety for clinical use is high, endovesical immunotherapy is not without complications. Arthralgia and arthritis are infrequent, but potentially severe, complications, the early diagnosis of which can allow adequate medical treatment and avoid chronification of the pathology. This case shows the therapeutic management of hip osteoarthritis in a 59-year-old woman, a rare and serious complication, secondary to a rare pathology such as reactive arthritis due to BCG instillation.

Inusual evolución de artritis reactiva tras inmunoterapia endovesical con BCG / Unusual evolution of reactive arthritis after endovesical immunotherapy with BCG

La instilación intravesical de BCG (Bacilo de Calmette-Guerin) es una terapia preparada con cepas debilitadas de Mycobacterium bovis y constituye un tratamiento complementario eficaz para el cáncer de vejiga superficial (no musculoinfiltrante o no invasivo) de alto riesgo. Aunque la seguridad para su uso clínico es alta, la inmunoterapia endovesical no está exenta de complicaciones. La artralgia y la artritis son complicaciones infrecuentes, pero potencialmente severas, cuyo diagnóstico temprano puede permitir un tratamiento médico adecuado y evitar la cronificación de la patología. El presente caso muestra el manejo terapéutico de la artrosis coxofemoral en una mujer de 59 años, una complicación grave e infrecuente, secundaria a una patología poco común como la artritis reactiva debida a la instilación de BCG
