Correction of ulnar deviation in patients with ulnar nerve injury by transferring the extensor digiti minimi tendon and then checking the amount of correction of the angle between the fifth and fourth finger by measuring the angle with a protractor
Design
A clinical trial without a control group and without blinding that is performed on 15 patients.
Settings and conduct
Patients with ulnar nerve injury rarely come to correct the deviation of the fifth finger, and this interventional surgery is performed very rarely. All surgeries are performed at Hazrat Fatemeh Zahra Hospital, affiliated to Iran University of Medical Sciences, by a professor of plastic surgery.
The extensor digiti minime tendon will be separated from the fifth metacarpophalangeal joint and moved from the fifth compartment of the extensor to the fourth compartment and sutured on the radial side of the fifth metacarpophalangeal joint in the position of correcting the deviation of the fifth finger.
Participants/Inclusion and exclusion criteria
Patients with a previous history of ulnar nerve injury of the hand, who have deviation of the fifth finger due to the weakness of the hypothenar muscles, and have a desire to correct the deviation of the fifth finger.
Intervention groups
Transferring the extensor digiti minimi tendon from the fifth finger and moving that from it`s extensor compartment.
Main outcome variables
The degree of correction of deviation of the fifth finger

Description
Intervention group: performing surgery to transfer the extensor tendon of digital mini-me and move its extensor compartment from 5 to 4 and re-stitch the tendon to correct the fifth deviation, which is performed by a plastic surgeon professor. The patient will wear an extensor brace for three weeks and then be referred for 2 months of physical therapy. Three months after the surgery, the degree of angle change and correction of the deviation of the fifth finger will be measured with a goniometer.
