Abstract
Objective To introduce the application of extensor digiti minimi tendon transfer(modified Tajima technique)for functional reconstruction of thumb opposition following median nerve palsy.Methods Thumb opponenplasty was done in 11 cases of high median nerve injury with irreversible palsy.Modified Tajima technique was used to transfer the extensor digiti minimi tendon.The proximal band was anchored onto the extensor pollicis longus tendon at the metacarpal neck.The distal band was inserted in the medullary cavity of the proximal phalanx.Results The patients were follow-up for 4 to 38 months with an average of 18.5 months.Thumb opposition was restored in all 11 patients with 100％ success rate.The extension of the donor finger was not affected.Conclusion Modified Tajima method is a simple and reliable method to reconstruct thumb opposition function.
