Abstract:
Objective:To investigate the efficacy of volar anatomical locking plates combined with dorsal mini-plates in treating com-plex distal radius fractures.Methods:We retrospectively included patients with complex distal radius fractures who had been treated with volar locking plates and dorsal mini-plates at Chongqing General Hospital from January 2019 to June 2023.The quality of articu-lar surface fragment reduction was assessed through image analysis.Follow-up data included the Mayo wrist score,Disabilities of the Arm,Shoulder,and Hand Questionnaire(DASH)score,wrist range of motion,time to fracture healing,and complications.Results:Twenty-eight patients[19 males,9 females;mean age,(45.4±11.9)years]were included,with a mean follow-up of 1(4.9±3.6)months.Their injury mechanisms included falls from height(11 cases),traffic accidents(9 cases),and simple falls(8 cases).After op-eration,the volar tilt was(5.1±4.9)°,and the ulnar inclination was(19.8±2.8)°;at the final follow-up,the angles were(5.2±4.8)° and(19.3±2.5)°,respectively,neither showing any significant change(P>0.05).At the final follow-up,all fractures healed,with a mean healing time of 3.6 months.At 1 year after operation,the wrist extension was(50.7±6.3)°;the wrist flexion was(49.4±6.1)°;the DASH score was 15.0±6.3;the Mayo wrist scores were excellent or good in 24 cases;the grip strength of the affected side averaged 84.4%of that of the contralateral side.No implant loosening occurred.Two cases of superficial wound infection and one case of exten-sor tendon irritation were reported.Conclusion:Locked volar plat-ing combined with dorsal mini-plating provides stable fixation for comminuted articular surface fragments in complex distal radius fractures,enabling early functional rehabilitation with favorable wrist recovery and low rates of dorsal tendon irritation.
