1 Back Pain in Children and Adolescents Christine Hom, M.D Division of Pediatric Rheumatology New York Medical College

2 Back Pain u Back pain in children - abnormal until proven otherwise! u 75% of children with back pain have an identifiable etiology u Adolescents more likely to have musculoskeletal pain or lower back pain syndromes

3 Back Pain u In children with back pain of >2 months duration: –33% had a post-traumatic etiology: occult fracture or spondylolysis –33% had kyphosis or scoliosis –18% had a tumor or infection

4 Back pain in adolescents u In a school based study of 446 adolescents aged 13-17y: u 26% of adolescents report some back pain, especially related to sports F Male:Female ratio 1:1 F 50% of tennis and soccer players F up to 85% of male gymnasts u Maneuvers requiring posterior extension of the leg often provoke lower back pain



7 Etiology of back pain u INFECTION –Sacroiliac infections –Vertebral osteomyelitis –Diskitis –Pyelonephritis –Potts disease –Spinal epidural abscess –Psoas abscess

8 Etiology of back pain u INFLAMMATION –Ankylosing spondylitis –Reiters syndrome –Inflammatory bowel disease –Spondyloarthropathy –SEA syndrome

9 Etiology of back pain u MECHANICAL –Musculoskeletal (sprain/strain) –Herniated disc u ORTHOPEDIC/TRAUMA –Spondylolisthesis –Spondylolysis –Scheuermanns disease –(Scoliosis) –Vertebral compression fracture

10 Etiology of back pain u MALIGNANCY –Spinal cord tumors (lipoma, teratoma) –Bone tumors F Osteoid osteoma F Ewings sarcoma F Vertebral osteosarcoma –Neuroblastoma –Leukemia –Eosinophilic granuloma –Aneurysmal bone cyst

11 Etiology of back pain u SYSTEMIC DISEASE –Secondary hyperparathyroidism (Stones, bones, groans, moans) –Sickle-cell anemia - back pain is common –Osteoporosis –Corticosteroid use –Aseptic necrosis –Nephrolithiasis

12 Etiology of back pain u OTHER –Fibromyalgia –Reflex sympathetic dystrophy –Conversion disorder –Pain amplification syndrome –Psychogenic

13 Evaluation of back pain u HISTORY and physical –point tenderness u CBC, ESR, SMA-20, urinalysis u Lyme titer u HLA-B27 u Plain films, including oblique views u Bone scan u CT/MRI

14 Evaluation of back pain u WARNING SIGNS –Increasing pain –Pain wakes child from sleep –Function: usual activities impaired –Weight loss –Fever –Bowel or bladder dysfunction –Young age, < 4 yo

15 Diskitis u Typical patient is 3-5 years old u Systemic findings: fever, irritability, abdominal pain, anorexia u Rigid posture; refuses to flex lumbar spine u Elevated ESR u Plain films reveal irregular vertebral endplates u CT/MRI reveal decreased signal in disk and increased in adjacent vertebrae u Usually hematogenous bacterial infection with S. aureus (88% no organism on aspirate)

16 Vertebral Osteomyelitis u Older children u Only accounts for 2-4% of osteomyelitis u Children appear more toxic: fever, irritability, refusal to walk u Elevated ESR, sedimentation rate u Radiographs show destruction of vertebral body u Organism usually recovered (S. aureus) on aspirate


18 Spondylolysis/spondylolisthesis u Defect of the pars interarticularis u Usually at L5 u Scottie-dog appearance on plain film –obtain oblique and lateral films u Complaints of low back pain, worse with palpation u Slippage of L5 on S1 is spondylolisthesis u in athletes with hyperextension of spine




22 Scheuermanns disease u Juvenile kyphosis u Painful in 50% of cases u Usually affects boys years of age u 75% of cases affect the thoracic spine u Fixed dorsal kyphosis u Compensatory lumbar lordosis

23 Scheuermanns disease u Lateral X-ray reveals Schmorls nodes and vertebral wedging with irregular vertebral endplates u The disease is self-limited with a benign course u Treatment: Nonsteroidal analgesics –severe cases may require bracing with an external Milwaukee brace for comfort


25 Enthesitis u Local tenderness to palpation at insertions of –tendon –ligament –capsule u On physical exam: –Patella at 10 oclock, 2 oclock, 6 oclock –Tibial tuberosity –Insertion of the Achilles tendon –Plantar fascia insertion onto calcaneus –Metatarsal heads –Greater trochanter of the femur –Anterior superior iliac spine

26 Juvenile ankylosing spondylitis u Chronic arthritis of peripheral and axial skeleton u Enthesitis u Seronegative (rheumatoid factor negative) u Extraarticular manifestations: acute iritis, rarely low grade fever, urethritis or diarrhea u ALL have sacroiliac arthritis u Genetic basis: 2-10% of HLA-B27 positive patients will develop JAS




30 Juvenile ankylosing spondylitis: New York AS criteria u expansion of lumbar spine u Pain at lumbar spine u Chest expansion 2.5 cm or less u AND –radiographic demonstration of sacroiliac arthritis (may be unilateral)


32 Juvenile ankylosing spondylitis u Iritis –Acute –Painful –Photophobia –Red eye –Anterior nongranulomatous uveitis –Few sequelae, but synechiae may develop –Episodic course most commonly seen in HLA-B27+ patients. If ANA positive, may develop chronic uveitis similar to JRA

33 Juvenile ankylosing spondylitis u HLA-B27 –Class I major histocompatibility antigen –varied presence in ethnic populations: F 50% of Canadian Haida Indians are HLA-B27+ F only 2% of Japanese general population –Incidence of JAS varies with HLA-B27 presence in a given population –10% risk of AS in children of HLA-B27+ patient with AS –20% risk of AS if they are also HLA-B27+ and male

34 Treatment of Juvenile AS u NSAIDs –tolmetin sodium (Tolectin) –indomethacin u Sulfasalazine u Intraarticular steroid injections u Local steroid injections at entheses u Physical therapy u New treatments include infliximab (monoclonal anti-TNF) and etanercept (sTNFR)

35 Juvenile ankylosing spondylitis u Children often develop peripheral arthritis years before axial involvement u Look for SEA syndrome: seronegative enthesitis and arthropathy u Complaints of pain in buttocks, groin, thighs, heels often predate frank sacroiliac disease

36 JRA or JAS?

37 DEXA Scan of Lumbar spine Look at Z-scores Percentage of bone mass relative to age matched controls Does not tell risk of fracture Risk of vertebral collapse more likely in pediatric population, rather than hip fracture Treatment: weight bearing exercise calcium, Vitamin D suppl. bisphosphonates

38 Pain amplification syndromes u Pain out of proportion to clinical findings u Pain does not follow anatomical boundaries u With autonomic findings –Chronic regional pain syndrome –Reflex sympathetic dystrophy –Causalgia/Sudecks atrophy u With painful tender points –Fibromyalgia u Hypervigilant –psychogenic/psychosomatic

39 Pain amplification syndromes u 80% are female u Median age 12 years u Mean duration of pain 1.6 years u Constant pain u Multiple locations u Lower extremity more often than upper u Role model for chronic pain u Personality: mature, excellent student, eager to please, many extracurricular activities

40 Pain amplification syndromes u Mother is the spokesperson and gives the history including subjective complaints u Incongruent affect: la belle indifference u Marked disability despite a paucity of physical findings u Other findings of headache, abdominal pain, sleep disturbance and fatigue u Allodynia - pain disproportionate to stimulus

41 Pain amplification syndromes Treatment u Physical therapy: –Aerobic exercise daily –Desensitization with toweling –Range of motion exercises u Cognitive behavioral therapy –Progressive muscle relaxation –Guided imagery –Self-hypnosis u Pharmacotherapy –Low dose amitriptyline or SSRI
