Artroplastia total de cadera primaria en pacientes con secuelas de poliomielitis / Primary total hip arthroplasty in patients with sequelae of poliomyelitis

Introducción: La prótesis total de cadera (PTC) en pacientes con secuelas de poliomielitis (SP) supone un reto quirúrgico. La morfología displásica, la osteoporosis y la debilidad glútea dificultan la orientación, incrementan el riesgo de fractura y reducen la estabilidad del implante. El objetivo de este estudio es describir una serie de pacientes con SP tratados mediante PTC. Material y métodos: Estudio descriptivo retrospectivo de pacientes con SP intervenidos mediante PTC entre 1999 y 2021 en un hospital de tercer nivel, con seguimiento clínico y radiológico y evaluación funcional y de las complicaciones hasta el presente o hasta el fallecimiento, con un mínimo de 12meses. Resultados: Se intervinieron 16 pacientes, implantándose 13PTC en el miembro parético, 6 por fractura y 7 por coxartrosis, mientras que las otras 3PTC se implantaron en el miembro contralateral. Se implantaron 4 cotilos de doble movilidad como medida antiluxante. Al año postoperatorio, 11 presentaban un balance articular completo sin aumentar los casos de Trendelenburg. El Harris Hip Score (HHS) mejoró 32,1puntos, la escala visual analógica (EVA), 5,25puntos, y la escala de Merlé-d’Augbiné-Poste, 6puntos. La corrección de la discrepancia de longitud fue de 13,77mm. La mediana del seguimiento fue de 3,5años (1-24). Dos casos se revisaron por usura del polietileno y 2 por inestabilidad, sin registrarse infecciones, fracturas periprotésicas o aflojamiento del cotilo o vástago. Conclusiones: La PTC en pacientes con SP permite mejorar la situación clínico-funcional con una tasa de complicaciones aceptable. El riesgo de luxación podría minimizarse con cotilos de doble movilidad.(AU)

Introduction: Total hip arthroplasty (THA) in patients with residual poliomyelitis (RP) is a surgical challenge. Dysplastic morphology, osteoporosis and gluteal weakness hinder orientation, increase fracture risk and reduce implant stability. The aim of this study is to describe a series of patients with RP treated by THA. Material and methods: Retrospective descriptive study of patients with RP treated with THA between 1999 and 2021 in a tertiary hospital, with clinical and radiological follow-up and functional and complication evaluation until present or death, with a minimum of 12months. Results: Sixteen patients underwent surgery, with 13THA implanted in the paretic limb, 6 for fracture and 7 for osteoarthritis, while the remaining 3 were implanted in the contralateral limb. Four dual mobility cups were implanted as an antiluxation measure. At 1year postoperatively, 11 had complete range of motion with no increase in Trendelenburg cases. The Harris hip score (HHS) improved 32.1points, the visual analog scale (VAS) 5.25 points, and the Merlé-d’Augbiné-Poste scale 6 points. The length discrepancy correction was 13.77mm. Median follow-up was 3.5years (1-24). Two cases were revised for polyethylene wear and two for instability, with no infections, periprosthetic fractures, or cup or stem loosening. Conclusions: THA in patients with RP allows improvement of the clinico-functional situation with an acceptable complication rate. The risk of dislocation could be minimized with dual mobility cups.(AU)

[Long-term clinical and radiological outcomes in a serie of 26 cases of symptomatic adult developmental dysplasia of the hip managed with bernese periacetabular osteotomy]. / Evolución clínico-radiológica a largo plazo en una serie de 26 pacientes con displasia de cadera del adulto sintomática tratados mediante osteotomía periacetabular bernesa.

OBJECTIVE: Developmental hip dysplasia is a frequent cause of coxofemoral pain in young adults. Bernese periacetabular osteotomy emerges as a possible option for the management of pain relief and functional limitation, in order to delay the need for arthroplasty in these patients. MATERIAL AND METHODS: A descriptive-retrospective study was conducted on 26 selected patients with symptomatic developmental hip dysplasia treated with bernese periacetabular osteotomy between 1996 and 2009 (94% women). Mean age at time of surgery was 39.8 y (15-49 y), with a mean follow-up of 10 years. Osteoarthritis (OA Tönnis scale), acetabular index and Wiberg angle were evaluated by radiology and functionality was valued by using the de Merle-D'Aubigné-Postel scale. RESULTS: The mean hospitalization time was 10 days. At 10 years, the mean radiography value of acetabular index was 9.03° and 38.3° for Wiberg angle (17° and 27° correction, respectively, above the mean pre-operative values). Joint lock was referred to by 43% of patients, and 53% to non-evidence based limb failure. Mean functional value was 14.30 (Good). At 5 years of follow-up, 20% advanced at least by one grade in OA Tönnis scale compared to their pre-operative status, increasing to 55% at 10 years. At 10 years after surgery, 83% patients did not need arthroplasty and 85% showed high satisfaction level. CONCLUSIONS: Bernese periacetabular osteotomy is a useful alternative in young adults with symptomatic developmental hip dysplasia that can improve pain relief, femoral head coverage, and slow down coxofemoral osteoarthrosis progression in order to delay arthroplasty.
