Spine examination

Table of Contents

Introduction

Wash hands
Introduce self
Ask Patient’s name, DOB and what they like to be called
Explain examination and obtain consent
Expose upper body (but leave bra on in women)
General inspection: patient, e.g. age, pain/discomfort, signs of trauma; around bed, e.g. mobility aids, spinal brace

Look

Gait: walking aids, speed, phases of walking, stride length, arm swing
Inspect from behind
- Posture: asymmetry, scoliosis
- Skin and muscles: muscle wasting, scars, redness
- Soft tissue abnormalities: lipomas, hair growth (spina bifida), pigmentation, café-au-lait spots (neurofibromatosis)
Inspect from side (stand against wall): check for normal cervical lordosis, thoracic kyphosis, and lumbar lordosis (lost in spondylolisthesis and when in pain)

Feel

Ask about any pain before examining.

Spinous processes and over sacroiliac joints for alignment and tenderness
Paraspinal muscles for tenderness and increased tone
Consider spinal percussion over thoracic/lumbar spinous processes, using the same technique as in a respiratory exam or closed fist percussion (percussion tenderness = serious pathology such as malignancy, osteomyelitis, or compression fracture)

Move

Demonstrate movements first.

Lateral flexion: ‘Slide your hand down your leg’
Lumbar flexion (10-20˚) and extension: flexion ‘Touch your toes’, extension ‘Lean back as far as you can’
Cervical spine movements: flexion/extension (‘Touch your chin to your chest’), rotation (‘Look over your shoulder’), deviation (‘Touch you ear to you shoulder’)
Thoracic rotation: ‘Rotate your chest while sitting with your arms crossed’

Special tests

Mark midline 10cm above the dimples of Venus and 5cm below while standing, then re-measure distance in flexion (<5cm difference implies lumbar flexion limitation that may be due to ankylosing spondylitis if there are other symptoms/signs)

Measure chest circumference in expiration and inspiration. Around 7cm difference is normal (<5cm suggests ankylosing spondylitis).

With patient prone, passively flex knee and extend hip (anterior thigh pain = femoral nerve irritation, usually due to L2-4 disc herniation)

With patient supine, lift a leg to full flexion or until significant leg pain, then depress it slightly and passively dorsiflex foot (leg pain radiating down below knee = sciatic nerve irritation, usually due to L4-S1 disc herniation/facet joint impingement)

Ask patient to flex their hip and knee, then passively push that knee into the patient’s chest and push the contralateral thigh into the bed (pain = sacroiliac joint pathology)
