ABSTRACT
Objetivo: Comparar los resultados posoperatorios clínicos y radiográficos en dos grupos de pacientes: menor o igual a 55 años y mayor a 55 años, sometidos a una artroplastia total de tobillo de tercera generación. Materiales y Métodos: Se evaluó, en forma retrospectiva, a dos grupos de pacientes: menor o igual a 55 años (n = 13) y mayor a 55 años (n = 18), que fueron sometidos a una artroplastia total de tobillo de tercera generación. La edad promedio del grupo de menor o igual a 55 años era 42.8 (DE 6.4) y la del grupo mayor a 55 años, 65.7 (DE 8.8). Resultados: El seguimiento promedio fue de 36 meses (RIC 25-60). La etiología era principalmente postraumática en ambos grupos. El puntaje promedio de la escala AOFAS al año de la cirugía fue 76,69 (RIC 58-89) en el grupo menor o igual a 55 años y 85,22 (RIC 67-100) en el grupo mayor a 55 años. No hubo diferencias estadísticamente significativas entre ambos grupos en los ángulos alfa, beta y gamma; medidos en las radiografías con apoyo a los 2 meses y a los 2 años de la cirugía. Conclusiones: Nuestro estudio demostró que los resultados clínicos y radiográficos en pacientes más jóvenes serían comparables con los de pacientes más grandes en el seguimiento temprano. Se necesita un seguimiento a más largo plazo para determinar si el riesgo de revisión es más alto en los pacientes jóvenes, debido a la falla relacionada con el desgaste de la prótesis
Objective: To compare the clinical and radiographic postoperative outcomes in two groups of patients: younger 55 and older than 55-year patients undergoing a third-generation total ankle arthroplasty (TAA). Materials and Methods: Two groups of patients were retrospectively studied: younger 55 (n=13) and older 55-year patients (n=19) undergoing a third-generation TAA. Group younger 55 average age was 42.8 (SD, 6.4) and Group older 55 average age was 65.7 (SD, 8.8). Results: The average follow-up was 36 months (IQR, 25-60). The main etiology was post-traumatic conditions in both groups. The mean score of the AOFAS scale one year after surgery was 76.69 (IQR, 58-89) in the group younger 55 and 85.22 (IQR, 67-100) in the group older 55. There were no statistically significant differences between the two groups in the alpha, beta and gamma angles measured on weight-bearing radiographs at 2-month and 2-year postoperative controls. Conclusions: Our study shows clinical and radiographic short-term outcomes in younger patients are similar to those in older patients. Longer-term follow-up is warranted to determine if the revision risk is greater in young patients, due to failures related to prosthesis wear

BACKGROUND: Minimally invasive surgery has several advantages: minor pain, smaller incisions and less tissue damage than traditional open surgery. Hallux arthrodesis with an endomedullary screw fixation provides compression and axial stability. The aim of this study was to describe the procedure and evaluate our first results of the minimally invasive first metatarsophalangeal arthrodesis with an endomedullary screw combined with a crossed screw fixation. METHODS: We retrospectively studied 15feet, with a minimum 1year follow-up. Patients were evaluated with full-load radiographs and AOFAS score preoperatively and at last follow-up. RESULTS: Consolidation rate was 93.3%, radiological consolidation time was 18 weeks (14-60). Radiographic alignment was achieved with satisfactory results. The preoperative AOFAS score improved from a mean 49 to 90 (p=0.001). There was one postoperative superficial site infection, which healed and a patient developed a pseudarthrosis but it was asymptomatic. CONCLUSIONS: The minimally invasive metatarsophalangeal arthrodesis with an intramedullary screw is a secure procedure with comparable results to open techniques. LEVEL OF CLINICAL EVIDENCE: 4.
