Study On The Efficacy And Complications Of Open Reduction And Internal Fixation With Dorsal Approach In The Treatment Of Type C Distal Radial Fracture

Objectives : To study the clinical results and the incidence of complications of open reduction and internal fixation with dorsal approach in the treatment of type C distal radius fracture.Methods:This study included eight patients with distal radius fractures treated with open reduction and internal fixation using a dorsal approach in our hospital between September 2018 and December 2019,Postoperative regular follow-up and routine X-ray examination were conducted to observe the fracture healing status of the patients,and the volar tilt,radial inclination and radial height were measured.Range of motion,grip strength,and Gartland-Werley scores of the wrist were recorded,as well as the incidence of complications such as tendon irritation and rupture,neurological symptoms,and infection.Results: All patients were followed up for 9 to 13 months,and imaging results were obtained after the follow-up:volar tilt:(10.50±1.51)°,radial inclination:(19.63±1.41)°;radial height:9.5(8.3,11.0)mm.Range of wrist motion at the last follow-up: Palmar flexion Angle(49.63±2.45)°,dorsal extension Angle(55.13±3.09)°,pronation Angle(79.88±3.72)°,supination Angle(77.00±1.85)°.At the last follow-up,the grip strength ratio of the affected side to the healthy side was(78.00±2.45)%.The results of Gartland-Werley score of the patients:(5.38±3.068)excellent in 3 cases and good in 5 cases,and the excellent and good rate was 100%.All patients had bone healing,but no complications such as infection,tendonitis,tendon rupture,neurological symptoms,and secondary displacement of fracture occurred.Conclusions: The dorsal approach open reduction plate internal fixation for the treatment of C distal radius fracture can achieve satisfactory imaging results,postoperative wrist function significantly improved.It is worth popularizing in clinic.
