Abstract:
Objective To investigate the clinical effect of coronal bone structure matching(CBSM)in the treatment of dis-tal radius fracture.Methods A total of 39 cases of distal radius fracture between Jannary 2018 and Jannary 2022 were included in this study.Among them there were 22 males and 17 females with an average age of(48.9±16.3)years old,ranged from 22 to 65 years old.All patients were treated with open reduction and internal fixation with plates.Based on the measurement of CB-SM value on the X-ray film the next day after surgery.All patients were divided into matched group and mismatched group ac-cording to the coronal bone structure matching in the normal range or not.There were 27 patients in the matched group,includ-ing 15 males and 12 females,the age ranged from 22 to 64 years old with an average of(48.0±16.2)years old.AO classifica-tion of fracture was C1 in 6 cases and C2 in 21 cases;the operation time ranged from 1 to 6 days after injury;9 cases were com-plicated with ulnar styloid process fracture.There were 12 patients in the mismatched group,including 7 males and 5 females;the age ranged from 22 to 65 years old with an average of(48.8±15.8)years old.AO classification of fracture was C1 in 4 cases and C2 in 8 cases;the time from injury to operation ranged from 1 to 5 days;4 cases were complicated with ulnar styloid pro-cess fracture.The X-ray films were used to evaluate fracture healing,humeral height,ulnar angle and palm tilt angle at 3 months after operation.The range of wrist motion(pronation,supination,palmar inclination and dorsiflexion),function out-comes(Gartland-Werley score)and pain levels(visual analogue scale,VAS)were compared between the two groups at the last follow-up.Results The average follow-up time of 39 patients were(9.5±4.3)months,ranged from 6 to 14 months.All pa-tients healed in one stage without postoperative infection,fracture nonunion and fracture displacement occurred.Compared with match group at the last follow-up,the VAS in the mismatch group was increased[(2.5±1.3)points vs(1.6±1.0)points],the wrist pronation were decreased[(70.5±12.6)° vs(80.5±9.4)°],with statistically significant difference(P＜0.05).There was no sig-nificant difference in the range of motion(supination,palmar inclination,dorsiflexion)and excellent good rate between the two groups at last follow-up after operation(P＞0.05).Conclusion Wrist dysfunction,limited pronation,and wrist pain may occur when the postoperative matching degree of the distal radius fracture is not within the normal range.
