Ultrasound-guided minimal invasive fixation for metacarpus and phalange fractures / 中国医学影像技术

ABSTRACT

Objective To explore value of high-frequency ultrasound-guided minimally invasive fixation treatment for metacarpus and phalange fractures.Methods Totally 26 patients of acute metacarpus and phalange fractures were selected and randomly divided into experimental group and control group (each n =13).The patients in experimental group underwent ultrasound-guided closed reduction,while in control group underwent C-arm X-ray fluoroscopy-guided reduction.Then the patients in two groups were followed up,and the curative effect of both methods were observed.Results The successful rate of closed reduction was 76.92％ (10/13) in experimental group,while was 84.62％ (11/13) in control group (x2=0,P=1.00).C-arm fluoroscopy was performed (0.62±1.19) times in experimental group,and (3.46±0.78) times in control group (t=-7.21,P＜0.01).The average healing time of fracture was (5.45±0.64) weeks in experimental group and (5.71±0.78) weeks in control group.The excellent and good rate of total active motion (TAM) was 84.62％ (11/13) in experimental group and 92.31％ (12/13) in control group,respectively.The average grip strength was (32.22±2.44) kg in experimental group,and (34.11±2.74) kg in control group (all P＞0.05).Conclusion High frequency ultrasound-guided minimally invasive fixation is reliable in treatment of metacarpal and phalangeal fractures,which can significantly reduce X-ray radiation.
