title: [Evaluation of dysfunction of hand and clinical efficacy in patients with hirayama disease treated with surgery by Jebsen-Taylor Test].
abstract: OBJECTIVE
  To investigate the clinical efficacy of cervical anterior internal fixation and bone grafting fusion by comparative analyzing hand dysfunction in Hirayama disease patients using Jebsen-Taylor Test (JTT).
  
  
  METHODS
  From Feb 2010 to Jan 2014, 20 hirayama disease patients who underwent surgery were enrolled in Department of Orthopaedics, Peking University Third Hospital. JTT were evaluated for the 20 patients before and after surgery. Among them, 9 patients were evaluated before and at three months, one year and more than 2 years after surgery.
  
  
  RESULTS
  All sections of the JTT scale indicated that the patients with CSM exhibited a significant impairment compared with healthy adults. Each scale of JTT was improved after surgery in addition to picking up small objects and placing them in a can and simulated feeding. The whole time were improved from 72.3 s to 60.2 s.
  
  
  CONCLUSIONS
  JJT is a valid efficacy evaluation in assessing the impairment of hand and upper extremities of patients with Hirayama disease and the surgery can improve patients' hand function.
