Zancolli lasso tendon transfer for ulnar claw hand : a short term outcome analysis of sixteen cases

Abstract EN

Sixteen patients (28 fingers) with mobile claw hand deformity following low ulnar nerve palsy were reconstructed by Zancolli lasso procedure, using the flexor digitorum superficialis tendon transfer for the deformity correction.

Postoperatively, after follow up averaged 6.5 months, the outcome war evaluated only by the assessment of the claw deformity correction, and good results were attained in 81% of the patients, fair in 13 %, and poor in 6 %.

After this procedure at follow-up, swan neck deformity was developed in one case and insufficient finger flexion also in one, and none of them effect the cosmetic results.

This study supports that Zancolli lasso procedure is simple and safe to perform, it creates a functionally dynamic tenodesis, gives good cosmetic deformity correction with better patient satisfaction in selected cases with least possible complications.
