Effect Of Anatomic Volar Locking Compression Plate And External Fixation Stents For Treatment Of Distal Radial C₁C₂Type Unstable Fractures

Objective: Retrospective of comparative study of Volar locking compressionpressure plate （LCP） and external fixation stents for treatment of distal radial C₁C₂type unstable fractures in the clinical application and effect of Anatomic.Methods: This study to select the patients from the Second Hospital of DalianMedical University and Dalian Central Hospital from June2006to February2011during hospitalization and diagnosis for distal radial C₁.C₂type unstable fracturespatients. Choose68proper patients, of which male27example, female41example,aged from21to75years old,（average56.1）. All the patients divide into two groups,named the fixed stents groups and locking compression plate group. According to thefracture of AO typing, in the fixed stents groups including30example,（C₁type12example, C₂type18example）. In the palmar compression locking plate group38example,（C₁type13example,C₂type25example）. All patients were followed up for6to12months, and carry on statistics analysis the two treatments in the operative time,blood loss, fracture healing time, range of motion, radiographic parameters,complications, and wrist function of the Gartland-Werley score, excellent rate andpatient satisfaction indicators in the area.Results: Study found that, with two group of treatment at the time of operationand the amount of intraoperative bleeding, external fixator group intraoperative bloodloss was45±21.5ml, less than the palmar side of group LCP90±35.7ml, externalfixator group of fracture healing time was7.11±2.44weeks, volar LCP group7.24±2.10weeks,（P <0.05）, there was a significant difference between; in fracture healingtime （P>0.05）, there is no significant difference; in joint activities, at3monthspostoperatively when followed up, we found the volar locking plate group in the palmar flexion, supination is obviously superior to the external fixation group, P <0.05,differences statistical significance, the remaining activity had no significant difference.However, after6,12months of follow-up, palmar flexion, back extension, radialdeviation,, ulnar deviation,pronation, supination（P>0.05）, the difference was notstatistically significant; the imaging parameters, although the volar locking plate grouphas better effect of learning parameters, but the application of two independent samplesthe test（P>0.05）, no significant differences between the two groups; the locking plategroup in the postoperative Gartland-Werley function score than the external fixationgroup（P <0.05）, the difference was statistically significant; in addition, the externalfixation group excellent and good rate was83.3%, the volar locking plate group, theexcellent and good rate was92.1%（P <0.05）, the difference was statistically significant;P>0.05, there was not statistically significant.Conclusion: Through this research, volar locking compression plate and externalfixation were effective methods for the treatment of C₁C₂type distal radius unstablefractures. The volar locking compression plate in the early days of the carpal jointactivity, Gartland-Werley function score and postoperative excellent rate are better thanthose of external fixator. Our experience is for C₁C₂type unstable fractures, as far aspossible the use of volar locking compression plate for treatment, and the curative effectis reliable. In addition, the patient’s own choice was not be ignored when we treatmentthe fractures.
