Registration Number

Brief Summary

Meralgia paresthetica (MP) is one of the most common peripheral entrapment neuropathies of the lower limbs. It is characterized by paresthesia, pain, tingling, numbness, hypersensitivity, or other abnormal skin sensations on the anterolateral aspect of the thigh. The condition results from compression of the lateral femoral cutaneous nerve (LFCN) along its course, often occurring as the nerve exits the pelvis.The injection of 5% dextrose (D5W) under ultrasound guidance is a novel treatment method for peripheral nerve entrapment. However, there is limited evidence about the efficacy of this method for patients with MP. The investigators found D5W was more safe and effective than corticosteroids for patients with MP. Thus, this study aimed to evaluate the 6-month efficacy of ultrasound-guided injection of D5W for MP patients.

D5W groupinjectionThe patients received one session of ultrasound-guided 10ml D5W injection around the lateral femoral cutaneous nerve as it exited the pelvis.
Primary Outcome Measures
NameTimeMethod
visual analogue scale(VAS)baseline as well as 1month, 3 month, 6 months post-injection

VAS is one of the most common tool to assess pain severity for patients, ranging from 0(no pain) to 10(most possible pain).

Secondary Outcome Measures
NameTimeMethod
cross-sectional area(CSA) of the nervebaseline as well as 1month, 3 month, 6 months post-injection

CSA could reflect the compression of the nerve, to some extent
