Acu-Loc®2 VDR桡骨远端掌侧骨板系统:是一款真正适合桡骨解剖结构的掌侧骨板系统,远端锁定孔的设计及靶向定位器上不透射线定位柱的使用,可以精确的调节骨板相对于桡腕关节面的位置,从而保证桡骨远端关节面下获得最佳的支撑,保证了骨折断端的稳定性;另外其定向桡骨茎突螺钉的设计可以充分的固定桡骨茎突,确切的恢复并维持桡骨高度;骨板尺侧发散孔的设计可以加强尺侧的支撑,恢复中柱结构的稳定性;配备使用的Hexalobe六棱螺钉系统强度极高,使其在密质骨中性能极佳,临床使用取得了不错的疗效。
桡骨远端C型骨折:为关节内的多块骨折,其治疗必须恢复关节外的各种角度和关节面的连续性,关节面的连续与否直接决定了骨折后期关节功能的恢复和晚期关节炎的发生与否。桡骨远端掌倾角、尺偏角以及桡骨高度的恢复在治疗桡骨远端过程中同样重要,掌倾角的丢失可引起腕骨及背侧肌腱背侧滑脱,从而引起腕关节疼痛和抓握不稳;掌倾角和尺偏角发生变化时会使关节面应力改变。恢复桡骨高度的意义在于可以恢复腕关节周围肌肉的张力,从而恢复患肢手臂的握力及抓持力。
 
摘要
背景:桡骨远端C型骨折为关节内的多块骨折,其治疗必须恢复关节外的各种角度和关节面的连续性。桡骨远端掌倾角、尺偏角以及桡骨高度的恢复在治疗桡骨远端过程中同样重要,
目的:探讨使用Acu-Loc®2桡骨远端掌侧骨板系统修复桡骨远端C型骨折掌倾角、尺偏角以及桡骨高度的变化。
方法:2015年5月至2016年3月应用Acu-Loc®2桡骨远端掌侧骨板系统修复11例桡骨远端C型骨折患者。术前掌倾角为-31°至-4°,平均-12.45°;尺偏角6°-18°,平均11.18°;桡骨高度1.92-8.68 mm,平均5.28 mm。所有患者术后4周、8周、12周、半年复查X射线片。根据末次随访时腕关节标准前后位和侧位X射线片,观察关节面恢复情况,测量尺偏角、掌倾角及桡骨高度。采用Gartland-Werley评分标准评价腕关节功能。
结果与结论:①11例患者均获随访,随访时间7-15个月,X射线片示骨折均骨性愈合,愈合时间6-8周,平均6.5周,没有发生感染及内固定失效。术后X射线检查10例关节面平整,1例稍差(< 2 mm);②术后掌倾角8°-15°,平均11.55°,与术前比较差异有显著性意义(P < 0.05);尺偏角22°-27°,平均23.18°,与术前比较差异有显著性意义(P < 0.05);桡骨高度8.01-13 mm,平均11.03 mm,与术前比较差异有显著性意义(P < 0.05);③根据Gartland-Werley评分标准评价腕关节功能,优8例,良2例,差1例,优良率91%;④结果表明,Acu-Loc®2桡骨远端掌侧骨板系统可为桡骨远端C型骨折提供可靠固定及有效支撑,有效恢复掌倾角、尺偏角以及桡骨高度,是修复桡骨远端C型骨折的一种较好选择。

Abstract:

BACKGROUND: Distal radius C fractures belong to multiple fractures in the joint. Its treatment should recover various angles and joint surface continuity outside the joint. The recovery of palmar tilt angle, radial inclination angle and radial height is also very important for treating distal radius.

OBJECTIVE: To study the changes in palmar tilt angle, radial inclination angle and radial height after type C fractures of the distal radius repaired with Acu-Loc®2 VDR bone plate system.
METHODS: From May 2015 to March 2016, 11 cases of type C distal radial fractures were treated with Acu-Loc®2 VDR bone plate system. Preoperatively, the palmar tilt angle was -31° to -4° (-12.45° on average), and the radial inclination angle was 6° to 18° (11.18° on average), and the radial height was 1.92 mm to 8.68 mm (5.28 mm on average). X-ray films were observed at postoperative 4, 8 and 12 weeks and half a year in all patients. Palmar tilt angle, radial inclination angle and radial height were measured and observed using anteroposterior and lateral X-ray films during final follow-up. Wrist function was assessed with Gartland-Werley score.
RESULTS AND CONCLUSION: (1) 11 patients were followed and the postoperative follow-up ranged from 7 months to 15 months. X-ray films showed that the union of fractures was achieved in 6-8 weeks (6.5 weeks on average). No infection or internal fixation failure occurred. The articular facets were smooth in 10 patients and a little poor was found in 1 case (< 2 mm). (2) After operation, the palmar tilt angle was 8° to 15° (11.55° on average) (P < 0.05); the radial inclination angle was 22° to 27° (23.18° on average) (P < 0.05); the radial height was 8.01 mm to 13 mm (11.03 mm on average) (P < 0.05). (3) The results were excellent in 8 cases, good in 2 cases, and poor in 1 cases according to Gartland-Werley wrist function assessment; the excellent and good rate was 91%. (4) Acu-Loc®2 VDR bone plate fixation can provide reliable fixation and effective support for type C distal radius fractures, which can recover the palmar tilt angle, the radial inclination angle and the radial height, so the Acu-Loc®2 VDR bone plate is an ideal method to treat type C fractures of the distal radius.
