Broken Femoral Stems:
- Discussion:
- bending cantilever fatigue is caused by proximal loss of stem support while distally the stem is securely fixed;
- proximal cement breaks up, but distal portion of stem remains tightly fixed in place;
- subsequent medial migration or deformation of proximal stem results;
- radiolucent zones develop proximally, medial and lateral to the stem, and may progress to
stem failure;
