Study population: femoral fracture patients admitted in Rashid hospital and trauma centre Dubai

Brief summary: The goal of this observational study is to learn about the relative position of femoral nerve in relation to the femoral artery in patients scheduled for femoral fractures using ultrasound scanning.

The classical description of femoral nerve is that it lies immediately near to artery, but it is not always true. The nerve lies at a varying distance from the artery.

The main question it aims to answer are:

• Is the age sex and Body Mass Index affect the relationship between femoral artery and nerve?

Detailed description: The femoral nerve block is ideal for surgeries of the femur, knee, or anterior thigh and is often combined with a sciatic nerve block for near complete lower extremity analgesia. The classic teaching is that the femoral nerve lies lateral to femoral artery sandwiched between the fascia iliaca and iliopsoas muscle1.

Aim:

The objective of the study is to find out the anatomical variation in the site of the femoral nerve in relation to the femoral artery, with respect to the age, sex, weight and ethnicity of the patient.

Eligibility criteria: Inclusion Criteria:

* above the age of 18 coming for fixation of femoral fracture

Exclusion Criteria:

* below the age of 18
* patient not willing to participate
* patients with neurological illness that hinders from giving a valid consent
* patients with local pathology at inguinal region

Primary outcomes:
measure: Variability of anatomical position of Femoral Nerve with respect to Femoral artery - effect of age, sex and BMI
timeFrame: From the time the patient is positioned for ultrasound scanning to obtain a clear image of the femoral nerve until the measurement of the distance between the femoral nerve and artery is completed, assessed over a period of up to 6 hours.
