[Are there still indications for Colonna's capsular arthroplasty?]

The Colonna arthroplasty was used in previous years in the treatment of severe CDH in children or even in the treatment of severe incongruities or subluxations. For most of these indications, other techniques are currently used, owing to both the current rarity of severe dislocation and delayed diagnosis and to improved pelvic osteotomies, in some cases associated with open reduction. Despite its complications, the Colonna arthroplasty still gives very good results if it is performed with a perfect technique. Presently the only indications are subluxation in the older child, which is very rare in developed countries, and failures or sequellae of the initial treatment when the articular space is severely damaged. The Colonna operation has now become a salvation procedure.
