Abstract

Objective　To evaluate different classification of the central slip injury, put forward a new classification and analyze its curative effect.　Methods　A new clinic classification was put forward based on the former classification and new material studies, and the corresponding treatment measures before operation were confirmed according to the different classification of the central slip injury. 25 patients with boutonniere deformity were treated from March 2013 to June 2018. Conservative treatment was successful in 2 patients. And other 23 patients received surgical treatment. 18 of them were underwent Mitek bone anchor reattachment surgery and 5 of them were underwent traction wire surgery.　Results　According to the Dargan function rating method, 6~38 months clinical follow up revealed that excellent in 16 patients, good in 6, fair in 2, poor in 1. Excellent rate was 88% and efficacy was satisfactory.　Conclusions 　Based on the medical history and X-ray, judging the new clinical classification of the central slip injury before operation and determining the surgical method are practicable for the central slip injury management with satisfactory outcome.
