Analysis Of Clinical Efficacy Of Complicated Distal Radius Fractures Treated By Acu-loc Palmar Locking Plate Systems Via Modified Henry Approach

Objective : By retrospectively analyzing the clinical effect of the modified Henry approach and the traditional Henry approach combined with the Acu-Loc palm-locking plate system for the treatment of complex distal radius fractures,the aim was to explore the advantages and the postoperative curative effect of the modified Henry approach and the Acu-Loc palm-locking plate system in the treatment of unstable distal radius fractures,to provide a theoretical basis for further improving the diagnosis and treatment of unstable distal radius fractures.Methods: Fifty patients with unstable distal radius fractures were enrolled from April to June 2016 in Jilin University,China-Japan Union Hospital.According to the random number table,the patients were randomly divided into modified Henry approach group and the conventional Henry approach group.25 patients in each group,improved Henry approach group using the modified Henry surgical approach combined with Acu-Loc palm locking bone plate system treatment;traditional Henry approach group using the traditional Henry Surgical approach combined with Acu-Loc palm-locking plate system.All the patients were reviewed the X-ray film of the wrist joint on the regular sideafter operation.The articular surface of the distal radius was measured and compared with the preoperative contrast of the angle of inclination,ulnar deviation and Shortening of the radius value.The function of wrist joint was evaluated by Dienst ’s wrist function evaluation standard and modified Mcbride’ s wrist function evaluation standard,and the operative condition and postoperative complications were recorded.The data were statistically analyzed,with α= 0.05 as the test level,P<0.05 was statistically significant.The clinical efficacy between the two groups was compared and the difference between the two groups before and after surgery.Results:All the patients were followed up for 6 to 24 months.The average follow-up time was(11.7 ± 4.8)months.At 6 months after operation,radiographic examination showed that the distal radius of the articular surface of the two groups was flat,the radial bone without axial shortening,the position of the implant was good,found no fixation of internal fixation,non-traumatic arthritis,no fracture delayed healing or fracture Nonunion occurs.Two groups of patients compared with the preoperative received effective treatment.In the wrist function score and excellent and good rate,modified Henry approach group Dienst wrist function assessment of excellentand good rate was 96.00%(24/25),slightly higher than the traditional Henry group 92.00%(23/25),there was no significant difference(P>0.05).The excellent and good rate of modified Mcbride wrist function assessment was96.00%(24/25),which was no significant difference compared with 92.00%(23/25)of the conventional Henry’s approach group(P> 0.05).There was no significant difference between the two groups in the angle of palm inclination,ulnar deviation and the height of radius(P>0.05).The postoperative angle of palm inclination,angle of ulnar deviation and height of radius were significantly improved(P<0.05),the difference was statistically significant.Intraoperative conditions,modified Henry approach and the traditional Henry group compared to the former surgical time and fracture healing cycles are shorter,and the surgery before the high rate of repair of pronator muscle,postoperative median nerve stimulation rate is low,the difference was There was statistically significant.Conclusion :Acu-Loc distal radial locking plate system is a safe and effective method for the treatment of complex distal radius fractures.The operation is more flexible and convenient,the fracture reduction is satisfied and reliable.It can shorten the operation time and restore the function of wrist joint well.Allowing the limb to engage in early mild daily activities;modified Henry approach and traditional Henry approach can effectively reveal the fracture,conducive to intraoperative operation and have enough space to place the plate,but Modified Henry approach have less injury to the anterior pronator muscle,in the same fixation of the case,the incidence of postoperative complications related to the low rate of benign subjective patients with high rates of return,it is worth further promotion of clinical.
