Sentence examples for axis of the fixator from inspiring English sources

Some of these complications are explained by incongruence between the rotation axis of the fixator hinge and the anatomical rotation axis of the elbow [7, 8, 9].

To position the axis of the fixator hinge, it is essential to identify the elbow rotation axis on fluoroscopy and drill an axis pin (Kirschner wire) through it.

For some authors, it is important that the longitudinal axis of the fixator is parallel to the femoral diaphysis, following the anatomical axis of the femoral bone [1, 2].

Thus, to prevent the development of hallux valgus deformity, the axis of the external fixator must be aligned parallel to the anatomical axis of the second metatarsal in the transversal plane.

Thus, in an attempt to prevent the development of cavus deformity during and after lengthening, the axis of the external fixator must be as parallel as possible to the plantar surface at the medial aspect of the first metatarsal bone.

In our opinion and experience, strict radial application of the fixator pins, with correct alignment of the mobilisation axis to the main centre of motion of the wrist and avoidance of overdistraction, may be the critical points to achieve the beneficial effect of mobilising the transarticular external fixator [13].

For this reason, other authors consider that the body of the fixator has to be placed in parallel with the mechanical axis, preventing the valgus and the medial translation during the lengthening, [6] as shown in Fig. 6.

Therefore, it is impossible to place a hinged fixator in perfect alignment with the rotation axis of the elbow, as the latter migrates during flexion and extension.

In particular, it was hypothesized that the contact interfaces between the different fixator components play a major role for the prediction of the fixator stiffness.

Full weight-bearing were allowed after removal of the fixator.

Both occurred within 6 months after removal of the fixator.
