Abstract

PURPOSE

To study the angle of screw placement in relation to the scaphoid fracture plane and its effect on union after percutaneous fixation of scaphoid waist fractures.

METHODS

Twenty-four consecutive scaphoid waist fractures were retrospectively evaluated for the orientation of screws in relation to the fracture plane using a method in which the sum-of-smaller angles (SSA) in 3 different radiographs were used to correlate with time to fracture union.

RESULTS

All but one patient achieved union after percutaneous fixation of the scaphoid. Another patient required revision surgery within the study period for inadequate fixation. A shortened time to union was significantly correlated to larger SSA.

CONCLUSIONS

SSA may be a reasonable predictor of union after percutaneous fixation of scaphoid waist fracture. It can be reliably calculated using plain radiographs. An SSA of 190° or more correlated with union by 8 weeks postoperatively.

摘要

目的

研究经皮固定舟状骨腰部骨折时，螺钉置入角度与舟状骨骨折平面的关系及其对骨折愈合的影响。

方法

回顾性评估连续24例舟状骨腰部骨折患者，采用一种通过3张不同X线片上较小角度之和（SSA）来关联骨折愈合时间的方法，以确定螺钉相对于骨折平面的方向。

结果

除1例患者外，其余所有患者经皮固定舟状骨后均实现骨折愈合。另1例患者在研究期间因固定不充分而需要翻修手术。愈合时间缩短与较大的SSA显著相关。

结论

SSA可能是经皮固定舟状骨腰部骨折后骨折愈合的合理预测指标。使用普通X线片即可可靠计算该指标。术后8周时，SSA为190°或更大与骨折愈合相关。
