Effects Of The Modified Bilhaut-Cloquet Surgery On The Treatment Of Congenital Duplication Of Thumb In Children

Objective: To study and compare the clinical therapeutic effects of the modified Bilhaut-Cloquet surgery on the treatment of congenital duplication of thumb (CDT) in children. Methods: A retrospective study was conducted on the 110 children with CDT who received surgical treatment in our hospital from November 2014 to November 2016. Namely, all the general information, conditions, operative methods, postoperative recovery qualities, complications, etc. of the patients were evaluated. Besides, the correlations between different operative methods and postoperative recovery conditions were explored. Results: Because some patients lost contact, eventually the follow-up data of 100 patients were collected and among these patients, no one had wound infection, necrosis, internal fixation removal, bone nonunion, myasthenia or relapse, etc. Among them, Bilhaut-Cloquet surgery was applied on 59 patients (Group A), and the other 41 patients were treated with the modified Bilhaut-Cloquet surgery (Group B). The incidence of adverse events in Group A (10.17%) was higher than that in Group B (4.88%). The scores of range of motion and appearance in Group B were all higher than those in Group A. However, the scores of joint stability and angular deformity in Group B were lower than those in Group A (All P<0.05). The excellent and good rate of Group B (95.12%) was significantly higher than that of Group A (83.05%). The logistic regression analysis indicated that the modified Bilhaut-Cloquet surgery was related to a better postoperative recovery. Conclusion: The modified Bilhaut-Cloquet surgery can decrease the incidence of adverse events, improve the scores of range of motion and appearance and enhance the overall therapeutic effects.
