Evaluación clinicorradiológica en hemiartroplastia de hombro / Clinical and radiological evaluation in hemiarthroplasty of the shoulder

Objetivo: Establecer los resultados funcionales y radiológicos a mediano plazo en pacientes con hemiartroplastia de hombro. Material y métodos: Se realizó un estudio transversal descriptivo con 25 pacientes operados de hemiartroplastia del hombro con artrosis glenohumeral de cualquier etiología, edad, sexo y ocupación. A todos los pacientes incluidos durante el período que va de noviembre a diciembre de 2002 se les realizó un abordaje deltopectoral y colocación de hemiprótesis modular cementada; de noviembre de 2000 a diciembre de 2002. Se les realizó una evaluación funcional (escala de Constant, 0-100 puntos) y radiológica en busca de “riesgo radiológico” de aflojamiento clínico protésico. Se realizó estadística descriptiva e inferencial para las variables del estudio. Resultados: La prevalencia de la patología quirúrgica fue del 0,4% del total de primeras consultas ortopédicas de primera vez, la edad promedio fue de 61,7 ± 12,49 años (rango: 32-85 años); sexo masculino, 8,6%, y femenino, 91,4%. La etiología más frecuente fue la degenerativa con 45,8% y el lado mas afectado fue el izquierdo, 54,3%. Con un seguimiento promedio de 19 ± 8,6 meses, la evaluación funcional fue de 60 ± 12 puntos; en la evaluación radiológica se identificó que el 20,8% de los pacientes presentaron “riesgo” radiológico para aflojamiento protésico, mientras que sólo el 4,2% de ellos no tuvieron línea de radiolucencia. Hubo mejoría estadísticamente significativa del dolor postoperatorio con respecto al preoperatorio (p < 0,05); la satisfacción promedio fue del 72%; hubo un 8,3% de complicaciones. Conclusión: En pacientes a los que aplicó hemiartroplastia de hombro, la funcionalidad del hombro operado se consideró como buena y la evaluación radiológica con resultado regular en pacientes con hemiartroplastia de hombro a medio plazo(AU)

Objective: To determine the medium-term functional and radiological results in patients with hemiarthroplasty of the shoulder. Material and methods: A descriptive cross-sectional study was performed in 25 patients with glenohumeral osteoarthritis of any etiology, age, sex and occupation who underwent hemiarthroplasty of the shoulder using a deltopectoral approach with placement of a cemented modular hemiprosthesis; between November 2000 and December 2002. Functional evaluation (Constant 0-100 points) and radiological assessment were performed to determine the “radiological risk” of prosthetic clinical loosening. Descriptive and inferential statistics for the study variables were performed. Results: The prevalence of surgical disease was 0.4% of all first-time orthopedic consultations. The mean age was 61.7 ± 12.49 (range 32-85 years); men accounted for 8.6% and women for 91.4%. The most frequent etiology was degenerative (45.8%). The most frequently affected side was the left (54.3%). With a mean follow-up of 19 ± 8.6 months, functional evaluation was 60 ± 12 points; radiological evaluation showed that 20.8% of the patients presented “radiological risk” for prosthetic clinical loosening whereas only 4.2% showed no line of radiolucency. Postoperative pain was significantly lower than preoperative pain (p < 0.05); mean satisfaction was 72%. Complications occurred in 8.3%. Conclusion: The functionality of the operated shoulder was good and radiological evaluation showed satisfactory medium-term results in patients with hemiarthroplasty of the shoulder(AU)
