The Hip Abduction Maneuver (HAM) to diagnose meralgia paraesthetica.

Background: Meralgia paresthetica (MP) is a compressive neuropathy of the lateral femoral cutaneous nerve (LFCN), characterized by pain, paresthesia, and numbness in the anterolateral thigh. Despite its well-documented etiology, diagnosing MP remains challenging, as complementary tests such as electromyography (EMG) and ultrasound may yield normal results due to anatomical variations and the dynamic nature of nerve compression.

Objective: This study introduces the Hip Abduction Maneuver (HAM) as a novel diagnostic tool for LFCN compression and investigates its utility in clinical and intraoperative assessments METHOD: The maneuver, inspired by Hagert's triad, evaluates hip abduction weakness as a functional indicator of LFCN entrapment.

Total knee arthroplasty and persistent pain: a neuropathic perspective on peroneal and saphenous nerve compression.

Background: Total knee arthroplasty (TKA) is a common surgical procedure aimed at relieving pain and restoring function in patients with advanced knee osteoarthritis. However, up to 25% of patients report persistent postoperative pain, which remains a major clinical challenge. While mechanical and biological causes are well-documented, neuropathic pain due to dynamic nerve compression is often overlooked, particularly involving the common peroneal and saphenous nerves.
