Excessive lag screw slide (>15 mm) was associated with higher patient BMI. Patients with higher BMIs should be monitored to identify excessive slide.

While the use of anti-osteoporotic therapy was associated with more slide, this was almost exclusively seen in patients only prescribed vitamin D and calcium.
