结论螺钉髓内固定和震波治疗都是治疗第五跖骨干骺端骨折不愈合的有效方法。
Conclusions Both intramedullary screw fixation and shock wave therapy are effective treatments for fracture nonunion in the metaphyseal-diaphyseal region of the fifth metatarsal.
背景：目前治疗第五跖骨干骺端慢性骨不愈合的金标准是髓内螺钉固定。
Background the current "gold standard" for treatment of chronic fracture nonunion in the metaphyseal-diaphyseal region of the fifth metatarsal is intramedullary screw fixation.
应特别注意近端螺钉固定，在此案例下，使用单皮质螺钉推荐用于假体干部，而双皮质螺钉用于假体之下。
Special attention should be given to the proximal screw fixation. In this case the use of uni-cortical screws is recommended around the stem of the implant and bi-cortical screws below this level.
单皮质螺钉适于固定关节周围骨折时螺钉朝向关节面的情况，例如肱骨近端骨折。
Unicortical screws are indicated for periarticular fractures in which the screws are placed in the direction of an articular surface, such as in the proximal part of the humerus.
于股骨内髁PCL附着点处分别钻取前后两隧道，与胫后内外两隧道引出的重建韧带形成交叉，游离端使用可吸收螺钉固定。
Drill two tunnels at the PCL attachment point inside the thighbone, intersecting with the reconstructed 1igament from the two tunnels behind the shank, fixing the free end using the absorb bolt.
在内圈的一端，轴承通过偏心锁定环(图1.7)或者两个定位螺钉(图1.8)被固定在轴上。
At one end of the inner ring, the bearing is clamped to the shaft with an eccentric locking ring (Figure 1.7) or with two setscrews (Figure 1.8).
