ABSTRACT
Objective To investigate the clinical effect of mini -plate and kuntscher pin fixation in the treatment of metacarpus and phalange fracture.Methods 113 FMB and FPB patients were divided into OSG (58 patients)and CTG(585patients)group according to random number table.Statistics of postoperative recovery and complications in the two groups were collected and analyzed after research.Results In 58 patients of OSG group,the total active bending from 2 -5 metacarpophalangeal joints to phalangeal joints of 28 cases(48.28%,χ2 =8.562,P =0.035 )were beyond 220°,19 cases (32.76%,χ2 =8.935,P =0.024)were between 180 -220°, 11 cases (51.72%,χ2 =9.365,P =0.012)were less than 180°.The total active bending fromthumb metacarpopha-langeal articulation to interphalangeal joint of 30 cases (51.72%,χ2 =9.365,P =0.012)were beyond 220°, 18 cases (31.03%,χ2 =8.747,P =0.009)were between 180 -220°,10 cases (17.24%,χ2 =8.932,P =0.041) were less than 180°(P <0.05).Conclusion AO Mini -plates surgical method has advantage of parking position accuracy,dissection stable fixation,functional recovery soon and less complication in the treatment of FMB and FPB patients,which is worthy of promotion.
