RESUMEN
INTRODUCTION: metatarsophalangeal resection arthroplasty is considered a salvage surgical procedure able to improve the quality of life of patients with major forefoot deformities. MATERIAL AND METHODS: a retrospective observational study of 31 patients (36 feet) with major forefoot deformities operated at our institution was performed. Thirty two feet required additional surgery involving the first ray, most of them (72.2%) through MTP joint fusion. The mean follow-up period was 10.3 ± 4.6 years. Most patients were women (87.1%), the mean age was 74.2 ± 11.5 years. RESULTS: at the final follow-up, mean AOFAS score was 77.9 ± 10.2 points and mean MOxFQ score was 18.3 ± 8.3 points. Visual analog scale (VAS) for pain improved significantly from 7.5 ± 1.2 points to 3.4 ± 2.1 points on average. Good clinical results were also reported on ability to put on shoes comfortably. The mean resection arthroplasty spaces at the end of the study were 1.3, 1.8, 2.5 and 4.4 mm, for second to fifth rays, respectively. The mean sizes of remodeling osteophytes at the end of the study were 1.6, 1.4, 1.1 and 0.7 mm, respectively. Significant improvement was also achieved in the hallux valgus angle (HVA) and intermetatarsal angle (IMA) at the end of the study. CONCLUSION: in our experience, metatarsophalangeal resection arthroplasty continues to be a valid choice in patients with major forefoot deformities, with satisfactory long-term clinical and radiographic results.
INTRODUCCIÓN: la artroplastía de resección metatarsofalángica se considera un procedimiento quirúrgico de salvamento capaz de mejorar la calidad de vida de pacientes con deformidades importantes en el antepié. MATERIAL Y MÉTODOS: se realizó un estudio observacional retrospectivo de 31 pacientes (36 pies) con deformidades importantes en el antepié operados en nuestra institución. Treinta y dos pies requirieron cirugía adicional que involucró el primer metatarsiano, la mayoría de ellos (72.2%) a través de la fusión de la articulación metatarsofalángica. El período de seguimiento promedio fue 10.3 ± 4.6 años. La mayoría de los pacientes fueron mujeres (87.1%), con una edad promedio de 74.2 ± 11.5 años. RESULTADOS: en la última visita de seguimiento, la puntuación AOFAS promedio fue de 77.9 ± 10.2 puntos y la puntuación MOxFQ promedio fue de 18.3 ± 8.3 puntos. La escala visual analógica (EVA) para el dolor mejoró significativamente, pasando de 7.5 ± 1.2 puntos a 3.4 ± 2.1 puntos de media. También se constataron buenos resultados clínicos en cuanto a la capacidad de calzarse con comodidad. Los espacios de resección promedio al final del estudio fueron 1.3, 1.8, 2.5 y 4.4 mm para el segundo al quinto radio, respectivamente. Los tamaños promedio de los osteofitos por remodelación al final del estudio fueron de 1.6, 1.4, 1.1 y 0.7 mm, respectivamente. También se logró una mejora significativa en el ángulo de hallux valgus (AHV) y en el ángulo intermetatarsiano (IMA) al final del estudio. CONCLUSIÓN: en nuestra experiencia, la artroplastía de resección metatarsofalángica sigue siendo una opción válida en pacientes con deformidades graves del antepié, con resultados clínicos y radiográficos satisfactorios a largo plazo.

INTRODUCTION AND OBJECTIVE: Distal humerus fractures in the elderly frequently associated with poor bone quality and comminution, making it harder to achieve proper osteosynthesis. Our aim is to evaluate the radiological and functional results of open reduction and internal fixation of these fractures. MATERIAL AND METHODS: Retrospective study of 26 patients treated by open reduction and internal fixation between the years 2005-2010. Mean follow-up was 42 months. At final follow-up, a radiography evaluation (Knirk and Jupiter score) and clinical examination using Mayo Elbow Performance Score and Quick-Disabilities of the Arm, Shoulder and Hand Score was performed. Mean age of the group was 76.8 years (65-89), with 83% of the patients being female. Sixteen patients suffered type C fractures and 8 type A by AO classification. All underwent posterior surgical approach. RESULTS: Mean elbow flexion reached 118.86°, with a mean extension deficit of 25°. More than 3-quarters (79.1%) of the patients showed 0-1 grade degenerative changes on the X-ray films at final follow-up. Functional results reached an average 19.87 points on Quick-Disabilities of the Arm, Shoulder and Hand Score, and 85 points on Mayo Elbow Performance Score scores. Non-union occurred in 2 cases: distal humerus in one patient and olecranon osteotomy in another. Ulnar nerve neuropraxia was recorded in 2 cases, and radial nerve in one. All 3 recovered uneventfully. Revision surgery was required, with 2 patients needing hardware removal and one a new fixation. DISCUSSION: Treatment by open reduction and internal fixation with plating in elderly people for type A and C distal humerus fractures gives good functional results regarding this population, and thus scarcely disturbs their quality of life.
