The Mantero flexor tendon repair in zone 1

Mantero and colleagues have reported a modification of the Bunnell pull-out method for the repair of zone 1 flexor digitorum profundus (FDP) lacerations that allows active postoperative mobilization. We report a series of 24 FDP lesions in 20 adult patients treated with this technique. The mean duration of the rehabilitation regimen, which was followed by all patients, was 4.2 months. Functional assessment using Strickland's criteria demonstrated 23 excellent to good results and one poor due to a septic rupture. Nineteen of the 20 patients were satisfied with treatment and all but one of the patients returned to work within an average of 2.6 months after operation. In comparison to other zone 1 repair methods with active mobilization regimens, the Mantero technique gives better functional outcomes and appears to be more reliable.
