The Clinical Effect Of Closed Reduction And Percutaneous Pinning For The Treatment Of Surgical Neck Fractures Of Proximal Humerus

Objective:To observe the clinical effect of closed reduction and percutaneous pinning for the treatment of surgical neck fractures of proximal humerus.Methods:A retrospective analysis of 19 patients with surgical neck fractures of proximal humerus treated in our department from February 2017 to December 2018.After closed reduction and percutaneous pinning in all patients,the tails of Kirschner wire were connected with bone cement to prevent withdrawal in 7 patients.In the other 12 patients,the tails were connected to the unilateral external fixation to increase the stability.The purpose of this article is to introduce this minimally invasive method and its improvement process,and to compare the shoulder Constant scores of patients treated with this technique at 3 months,6 months and 12 months.Results: The nail withdrawal rate of Kirschner wire combined with external fixator was lower than that of Kirschner wire combined with bone cement fixation.The Constant score of patients treated with closed reduction and percutaneous pinning was significantly different between 3 months and 6months(P<0.05),but there was no significant difference between 6 months and 12 months(P>0.05).Conclusions:The technique of closed reduction and percutaneous pinning for the treatment of humeral surgical neck fracture has the advantages of minimal trauma,short healing time,quick recovery.It can be used as an alternate method for surgical neck fracture,and is in line with modern minimally invasive treatment concepts.
