Abstract： Objective To explore the anatomy and clinical significance of fixation combined with limited outside cut restoration gram needle internal fixation for distal radial fractures. Methods Based on the anatomical observation and measurement of the forearm and hand. Found out the distal radial fractures fixed bracket screws and gram needle safety area and the needle into the body, and made reasonable angle respectively, to formulate standardized orientation, and applied to clinical procedures, and the clinical cases were followed up. The clinical curative effect was observed. Results The place for the fixed bracket screws of the second metacarpal was the nail parts of radial dorsal partial ends. The proximal fracture for external fixation stents bolt into the nail near abductor muscle and manipulation long in the thumb short extensormuscles. Its feet side for stabbing abductor muscle and refers to a long stretch of radial side for tendon, radial side wrist short stretch muscles. The farthest distance between the lister nodule was (63.69 ±3.00) mm,nearest distance between the lister nodule was(123.64 ±5.00)mm. Gram needle do limited internal fixation security clearance for thumb long stretch tendon and refers to stretch tendons,radial side wrist length stretch tendons, thumb short extensor tendons, stretch retinaculum and this gap proximal distance lister nodule for ( 33. 52 ± 4.20) mm, remote distance lister nodule for( 8.81 ± 0. 88) mm. In clinical applications, wrist imaging recovery, function of ratings had no significant difference ( P ＞ 0.05). But the postoperative complications of the two sets of patients had statistically significant difference ( P ＜ 0. 05 ). Conclusion According to the anatomy of distal radial fractures,from the results of our research applied in fixation distal radial fractures in the operation,it had the advantages of simple operation,reset good,fixed firmly,and small trauma. It was worth of used widely in clinical.
