BMI: body mass index
AO/OTA: AO Foundation/Orthopaedic Trauma Association
LFCN: lateral femoral cutaneous nerve
In cases where the LFCN was medial to the screw, the medial edge of the screw head was used to measure the LFCN-to-implant distance. In cases where the LFCN position was lateral to the screw, the end of the rod was used.
Symptom of LFCN disorder: (postoperative symptom) → (symptom after implant removal). +: symptom, –: no symptom
