What is one of the complications associated with the improper use of crutches?

Improper use of crutches can lead to complications such as axillary nerve damage. This can occur if the crutches are not fitted correctly or if excessive pressure is applied to the axilla (the area under the arm) while using the crutches. The axillary nerve runs in close proximity to this area, and continuous weight-bearing on the crutches can compress this nerve, leading to pain, weakness, and potential numbness in the shoulder and upper arm. It is important for users to be educated on the proper techniques for crutch use, including the appropriate grip and positioning, to prevent such complications.

The other options do not directly relate to common issues arising from improper crutch use. For instance, solar plexus nerve damage is not typically associated with crutch usage, and while carpal tunnel syndrome involves nerve damage, it is primarily linked to repetitive wrist motion rather than the use of crutches. Trigeminal nerve damage pertains to facial sensation and motor functions and is unrelated to how crutches are utilized. Thus, axillary nerve damage is the most relevant concern regarding crutch use.
