Conclusion

Injection-related MN injury can cause lasting and debilitating sensory motor deficits. As such, precision in needle placement for injection is paramount. Many studies exist with respect to injection location, but a lack of consistent data related to injury prevention exists. On the basis of anatomic measurements, we have concluded that the safest injection location site is located on the ulnar aspect of the FCR tendon or 8 to 10 mm radial to the midpoint of the wrist while maintaining an injection site that is radial to the PL tendon.
