Legg-Calve-Perthes (LCP) disease can result in morphological deformities and associated adult hip arthritis. Thirty-five consecutive total hiparthroplasties (THA) were performed in 28 patients with a history of LCP using a non-cemented modular femoral component. There was one revision for late hematogenous infection and no evidence of prosthesis failure. Harris hip scores, on average, improved from 49.8 (26-73) to 93.9 (82-100) (P<0.05) after a minimum of 2years follow-up (average, 8.2years, range 2-14years). Clinically, patients demonstrated diminished or no limping (94%, 33/35) and improved leg length equality post-operatively (100%, 35/35). This style of stem accommodated metaphyseal/diaphyseal size mismatch in 80% (28/35), allowed for abnormal anteversion in 71% (25/35), and resulted in radiographic improvements in trochanteric height (P<0.05), body weight lever arm (P<0.05), and leg length (P<0.05).

Legg-Calvé-Perthes (LCP) es una enfermedad puede dar lugar a deformidades morfológicas y asociado artritis de cadera del adulto. Treinta y cinco hiparthroplasties totales consecutivos (THA) se llevaron a cabo en 28 pacientes con una historia de LCP utilizando un componente femoral no cementado modular. Había una revisión para la infección hematógena tarde y no hay evidencia de insuficiencia prótesis. Las puntuaciones de cadera de Harris, en promedio, mejoró de 49,8 (26-73) a 93,9 (82-100) (p <0,05) después de un mínimo de 2 años el seguimiento (promedio, 8.2years, 2-14years rango). Clínicamente, los pacientes mostraron una disminución o ninguna cojera (94%, 33/35) y la igualdad mejora de longitud de las piernas después de la operación (100%, 35/35). Este estilo de vastago acomodó metafisaria / diafisaria tamaño desajuste en el 80% (28/35), permitió anteversión anormal en el 71% (25/35), y dio lugar a mejoras radiográficos de altura del trocánter (p <0,05), el brazo de palanca de peso corporal (P <0,05), y la longitud de las piernas (P <0,05).

    I precisely wished to appreciate you yet again. I am not sure the things I would’ve followed in the absence of those smart ideas contributed by you regarding my situation. Completely was a real frustrating case in my position, but noticing your specialised tactic you managed the issue forced me to weep over joy. I’m happier for the work and even have high hopes you realize what an amazing job that you are doing training many people all through your blog post. I’m certain you’ve never got to know all of us.

    Aw, this was a actually nice post. In thought I’d like to put in writing like this furthermore – taking time and actual effort to create a really excellent article… but what can I say… I procrastinate alot and by no means seem to get some thing performed.

    VCzjMn It as not that I want to copy your web-site, but I really like the pattern. Could you let me know which theme are you using? Or was it tailor made?
