And incisional method is simple: rang of rotation is large. The method is more ideal to repair soft tissue defect in lower segment leg and foot.
而且切取方法简单，旋转范围大，是修复小腿下段及足部软组织缺损较为理想的一种方法。

The models of the cooperativephenylene ring rotation and the cooperative large segment torsion were built.
同时建立协同环旋转以及协同链段扭转的模型。

Results: The FJ play an important role in load transmission; they provide a posterior load-bearing helper, stabilizing the motion segment in flexion and extension and also restricting axial rotation.
