Analysis of risk factors of ulnar neuritis after open arthrolysis in patients with elbow stiffness
Objective:To investigate the risk factors of ulnar neuritis after open arthrolysis in patients with elbow stiffness.Methods:A retrospective study was conducted on 96 patients who underwent open arthrolysis for elbow stiffness from April 2020 to June 2021.The study involved assessing postoperative maximal improvement in flexion arc,the maximal improvement in extension arc,and the occurrence and outcome of ulnar neuritis.Results:According to the inclusion and exclusion criteria,59 males and 37 females aged 14 to 62 years were enrolled,with an average age of(37.3±10.7)years.A total of 29 patients developed ulnar neuritis after the operation,including 28 patients with McGowan type Ⅰ and 1 patient with McGowan type Ⅱ.The follow-up period ranged from 12 to 25 months,with a mean of(17.1±4.0)months,symptoms were completely resolved in 27 patients.Binary logistic regression analysis showed that gender,original injury type and postoperative maximal improved flexion arc were the main risk factors for ulnar neuritis after open arthrolysis for elbow stiffness.The risk of postoperative ulnar neuritis in females was 3.712 times that of males(OR=3.712,95％CI:1.592-8.653);the risk of postoperative ulnar neuritis in patients with peri-elbow fracture or dislocation was 4.552 times that of patients with an extra-elbow fracture or non-fracture(OR=4.552,95％CI:1.053-19.681);the risk of ulnar neuritis in patients with postoperative improved flexion arc more than 60° was 14.184 times that of patients with postoperative improved flexion arc less than 30°(OR=14.184,95％CI:2.199-91.478).Conclusions:The incidence of postoperative ulnar neuritis is relatively high after open arthrolysis for elbow stiffness.The main risk factors for postoperative ulnar neuritis include a history of peri-elbow fracture or dislocation,female,or a postoperative maximal improved flexion arc of 60° or more.
