[Effectiveness comparison between ultrasound-guided and C-arm-guided in closed reduction and pinning for treatment of metacarpophalangeal fractures].

OBJECTIVE

To compare the effectiveness between ultrasound-guided and C-arm-guided in closed reduction and pinning for the treatment of metacarpophalangeal fractures.

METHODS

The clinical data of 30 patients with metacarpophalangeal fractures between October 2015 and November 2016 were retrospectively analyzed. According to different treatments, the patients were divided into ultrasound group (using ultrasound-guided closed reduction and pinning, n=15) and C-arm group (using C-arm-guided closed reduction and pinning, n=15). There was no significant difference in gender, age, disease duration, causes of injury, injured finger, location of injury finger, fracture classification between 2 groups ( P>0.05). The status and success rate of reduction were compared (excellent, good, and acceptable grades could be regarded as the successful reduction). The operation time, intraoperative fluoroscopy times, and fracture healing time were recorded. And the postoperative functional recovery was evaluated according to the total active movement (TAM) by the standard functional evaluation issued by Hand Surgery Association of Chinese Medical Association.

RESULTS

The operation time of ultrasound group was longer than C-arm group, and the intraoperative fluoroscopy times was less than C-arm group, all showing significant differences ( P<0.05). There was no signifi cant difference in the grade and the success rate of reduction between 2 groups ( P>0.05). All the patients were followed up 6-18 months (mean, 10 months), without malunion, joint stiffness, tendon adhesions, and other complications. There was also no significant difference in the fracture healing time, the grade of TAM, and the excellent and good rate of TAM between 2 groups ( P>0.05).

CONCLUSION

The treatment of ultrasound-guided closed reduction and pinning for metacarpophalangeal fractures is effective, which is a feasible auxiliary method of closed reduction and fixation for fracture. And less fluoroscopy can reduce the radiation damage of operation.
