Zancolli’s procedure: technique and indications
Anatomical variations in the distal insertion of the abductor pollicis longus (APL) muscle onto the 1st metacarpal bone and around the 1st carpometacarpal joint led Eduardo Zancolli to introduce a surgical yet conservative partial APL tenotomy targeting its accessory or supernumerary distal bundles....

Summary: | Anatomical variations in the distal insertion of the abductor pollicis longus (APL) muscle onto the 1st metacarpal bone and around the 1st carpometacarpal joint led Eduardo Zancolli to introduce a surgical yet conservative partial APL tenotomy targeting its accessory or supernumerary distal bundles. Following an anatomical and pathophysiological review, we will describe the surgical technique for this minimally invasive extra-capsular procedure. Results and operative indications of this very simple technique are reported as well, which can be performed in Dell stage I or II of trapeziometacarpal osteoarthritis when well-conducted conservative medical treatment has failed to achieve pain relief.
La variabilité d’insertion de l’abductor pollicis longus (APL) sur la base du premier métacarpien et autour de l’articulation trapézo-métacarpienne a conduit Edouardo Zancolli à proposer une intervention de ténotomie d’affaiblissement de l’APL et surtout de ses faisceaux accessoires ou surnuméraires. Après un rappel anatomique et physiopathologique, la technique chirurgicale de cette intervention extra-articulaire simple est décrite. Ses résultats et ses indications sont rapportés, elle peut être envisagée dans les stades I ou II de Dell d’une rhizarthrose après échec d’un traitement médical conservateur bien conduit. |
