AVIP Project (Prosthetic Virtual Friend): Study of clinical-functional outcomes and satisfaction with a mobile application in the perioperative management and follow-up of hip arthroplasty. / Proyecto AVIP (Amigo VIrtual Protésico): estudio de resultados clínico-funcionales y de satisfacción con una aplicación móvil en el manejo perioperatorio y seguimiento de implantes protésicos de cadera.

OBJECTIVE: To analyze the clinical, quality of life, and healthcare quality outcomes obtained in a series of patients undergoing total hip arthroplasty (THA), who were empowered and monitored using the AVIP application. These results will be compared with a control group followed through a standard protocol. MATERIAL AND METHOD: Randomized clinical trial with parallel groups involving patients with an indication for THA. Clinical variables were measured and compared using the WOMAC and mHHS, pain assessed by the VAS, quality of life with the SF-12 test. Walking capabilities were analyzed using the Functional Gait Assessment Scale, along with satisfaction levels assessed through the SUCE questionnaire, and perceived anxiety levels related to the process. RESULTS: A total of 68 patients were evaluated, with 31 patients in the AVIP group and 33 in the Control group completing the follow-up. Both groups demonstrated improvement in clinical outcomes based on the WOMAC and mHHS hip tests, a reduction in perceived pain, and an enhancement in quality of life according to the SF-12 test. Patients in the AVIP study group exhibited non-inferiority in clinical outcomes and satisfaction compared to the control group, as well as lower anxiety levels and improved walking capabilities after the first month of follow-up. Notably, 82.25% of the follow-up visits for this group were conducted remotely. CONCLUSION: The implementation of a mHealth application like AVIP can be safely offered to selected patients undergoing hip arthroplasty, enabling effective monitoring and providing continuous information and training.

[Femoral revision surgery with fully coated stems. Long-term results of 78 cases]. / Cirugía de revisión femoral con vástagos monobloque de recubrimiento completo. Resultados a largo plazo de 78 casos.

INTRODUCTION: Loss of bone stock and anatomical alteration of the proximal femur make femoral revision surgery a complex procedure in which the choice of implant will be critical. Our goal is to assess the clinical and radiological results of complete coating Monoblock stems. MATERIAL AND METHODS: Retrospective study of 78 consecutive cases of femoral review surgery intervened by our unit. RESULTS: The average follow-up was 122 months. The average score on the Harris Hip Score was 81.2 ± 11.4 points. An age of less than 65 years, a minor femoral defect according to Paprosky classification (I, II and IIIA), the existence of a single previous surgery and the non-occurrence of intra or postoperative complications, was associated with better clinical and functional outcomes (p < 0.05).Cumulative survival was 96.7% at age 10 if we consider as failure the removal of the stem by aseptic loosening and 92% if we consider withdrawal for any cause to fail. CONCLUSION: Despite the current tendency to use modularity in femoral review surgery and given the results presented, we consider that complete coating monoblock stems provide a firm and stable fixation. However, the worst results in patients with major defects have led to other options being considered.

INTRODUCCIÓN: La pérdida de stock óseo y la alteración anatómica del fémur proximal hacen de la cirugía de revisión femoral un procedimiento complejo en la que la elección del implante será fundamental. Nuestro objetivo es valorar los resultados clínicos y radiológicos de los vástagos monobloque de recubrimiento completo. MATERIAL Y MÉTODOS: Estudio retrospectivo de 78 casos consecutivos de cirugía de revisión femoral intervenidos por nuestra unidad. RESULTADOS: El seguimiento medio fue de 122 meses. La puntuación media en la escala de Harris Hip Score fue de 81.2 ± 11.4 puntos. Una edad menor de 65 años, un defecto femoral menor según la clasificación de Paprosky (I, II y IIIA), la existencia de una única cirugía previa y la no aparición de complicaciones intraoperatorias o postoperatorias se asoció con mejores resultados clínicos y funcionales (p < 0.05). La supervivencia acumulada fue de 96.7% a los 10 años si consideramos como fracaso la retirada del vástago por aflojamiento aséptico y de 92% si consideramos como fracaso la retirada por cualquier causa. CONCLUSIÓN: Pese a la tendencia actual al uso de la modularidad en cirugía de revisión femoral y dados los resultados presentados, consideramos que los vástagos monobloque de recubrimiento completo proporcionan una fijación firme y estable. Sin embargo, los peores resultados obtenidos en pacientes con defectos óseos mayores han provocado que se valore otro tipo de opciones.

Treatment of intraarticular calcaneal fractures by reconstruction plate. Results and complications of 86 fractures. / Tratamiento de las fracturas intraarticulares de calcáneo mediante placa de reconstrucción. Resultados y complicaciones de 86 fracturas.

OBJECTIVE: To evaluate the results of surgical treatment of intraarticular calcaneal fractures, and also to analyze the variables that influence the final clinical and radiological outcomes as well as the complications. MATERIAL AND METHODS: We retrospectively analyzed 86 intraarticular calcaneal fractures in 78 patients, who underwent surgery with an extended lateral approach and reconstruction plate. The mean age was 48 years (16-74 years) and the mean follow-up was 4.6 years (9-99 months); 54 patients (69.2%) suffered falls from less than 3m in height or banal injuries and 24 patients (30.8%) falls from more than 3m in height or high energy-accidents. According to the Sanders classification we operated 12 (15%) typeII, 54 (62.8%) typeIII and 20 (23.2%) typeIV fractures. RESULTS: The postoperative mean AOFAS score was 73.9 points, with good or excellent results in 57% of the patients. Twelve cases (14%) suffered surgical wound complications and 11 (12.8%) required subtalar arthrodesis. Significantly better results were obtained in the patients younger than 30 years old, patients that fell from less than 3m in height and patients with Sanders fractures types II and III compared to typeIV, which were associated with higher rate of subtalar arthrodesis. CONCLUSIONS: We consider that open reduction and internal fixation of intraarticular fractures of the calcaneus with reconstruction plate is a valid treatment alternative. Given the complications described and the secondary subtalar arthrodesis rate, we recommend a meticulous technique carried out by experienced surgeons.

Skin Abscess due to Serratia marcescens in an Immunocompetent Patient after Receiving a Tattoo.

The incidence of skin infections caused by Serratia marcescens is extremely low and such infections are typically observed in immunocompromised patients. The clinical manifestations of these infections include cellulitis, abscesses, fluctuant nodules, or granulomatous lesions. Infections caused by S. marcescens are very difficult to treat due to their resistance to many antibiotics, which often leads to specific and prolonged treatment. Infections after receiving a tattoo are very rare and are caused by unhygienic conditions or the inexperience of the tattooist. In this paper we present the case of a 32-year-old male with no comorbidity, who presented an abscess caused by S. marcescens in a area that was tattooed one month earlier. The case was resolved with surgery and antimicrobial therapy that was based on the antibiogram. To our knowledge, this is the first reported case of a S. marcescens skin infection following a tattoo, in the absence of immunosuppression.
