Most common bacteria in septic arthritis and osteomyelitis
- Staph Aureus
- GAS
- H influenzae
Investigations in septic/osteomyelitis
- FBC
- ESR/CRP
- Blood culture
- Xray (usually normal)
- Bone scan
Management of septic/osteomyelitis
- Refer to orthopaedics
- Urgent aspiration in septic +/- arthotomy and washout w/ Flucloxacillin
- Elevate and immobilise limb
- Analgesia
- Manage fluid input/output
- Admission
- Patient handout
- F/U with GP
Risk factors for osteomyelitis (in adults)
- Pentrating injuries
- Surgical contamination
- IVDU
- HIV
- DM
- Periodinitis
Management in transient synovitis
- Rest
- Regular analgesia
Paracetamol
Ibuprofen - Gentle skin traction
- R/V w. GP 3 days
- Return if febrile, unwell or getting worse
- If ongoing >4 weeks->OPD to rheumatology
Advice to parents about prognosis of transient synovitis
- Typically a benign course
- Recurrence is uncommon
- Close f/u recommended
- If pain worsens at any time or persists beyond 7-10 days, further F/U is warranted.
- May be the presenting feature sin a chronic inflammatory disease in 10% of cases
Approach to an acutely swollen joint
1. Injury Trauma Acute joint bleed 2. Pain and fever Septic arthritis Osteomyelitis 3. Recent diarrhea, viral, tonsillitis Reactive/post infective 4. History of IBD 5. Rash Vasculitis HSP 6. Recent drug ingestion Serum sickness 7. Bone pain, LN, hepatosplenomegaly Malignancy 8. >6 weeks, morning irritability, stiffness, gradual refusal to partake in usual activties Juvenile chronic arthritis 9. No clear diagnosis Symptomatic w/ rest and NSAID Review Re-evaluate diagnosis if not improved after 4 weeks
Etiology of acute swollen joint
- Trauma
- Acute joint bleed
- Septic A
- OsetoM
- Reactive
- IBD
- HSP, vasculitis
- Serum sickness
- Malignancy
- Chronic juvenile arthritis
Investigations in acute swollen joint
- Trauma-> Xray
Uncommon in very young, caution diagnosis. Prevents activity immediately - Acute joint bleed->Coagulation studies
May be first presentation of hemophilua - Septic->FBC, BC, aspirate, ESR/CRP, Xray
- Reactive->FBC, ESR/CRP, stool/urine/throat swab
- IBD->FBE, ESR, albumin, stool
- Vasculitis->ESR/CRP
- Malignany->FBE, ESR, Xray
- Juvenile arthritis->FBE, ESR, serum to store
Key features in reactive
- Monoarthritis of large joint
- If poly/migration->consider RF
- Parvo, rubella, EBV, mumps, Salmonella, shigella, CampyloB. Consider Reiters if conjuntivitis/uretrhitis
- Onset 7-14 dyas post
Important features in juvenile arthritis
- Peaks age 1-5 years
- ++Pain
- May affect any joint, multiple joints
- Rarely in hip as first presentation
Important considerations with FBE->leukocytosis/left shift, normal, -ve PLT/mild anemia, cytopenia/absent +PLT
- Leukocytosis/left shift often found in sepsis and in many reactive arthritides
- Usually normal in HSP and serum sickness
- Often have thrombocytosis and mild anaemia in JCA
- Cytopenias and absence of thrombocytosis in presence of elevated inflammatory markers suspicious of malignancy
When is ESR/CRP usually normal
- HSP
When do patients needs to be referred for inpatient
- Trauma->orthopedics
- Intra-articular bleeds->ortho/hematology
- Joint sepsis->ortho
- Suspected malignancy-> haem/oncology
- Other->general medicine
When to refer for OP rheumatology
- > 4 weeks duration
- Significant joint effusion
- Limitation of activity
- Multiple joints involved
- Joint contractures
- Vasculitis other than HSP
Etiology of non-weight bearing by age
1. Aged 1-4 years Congenital dysplasia of the hip Toddler fracture Transient synovitis Child abuse 2. Aged 4-10 Transient synovitis Perthe 3. >10 years Overuse Slipped upper femoral epiphyses 4. All children Trauma, NAI Bleed Infection Rheumatological, vasculitis Reactive Malignancy Intra-abdominal->appendicitis Inguinscrotal->testicular torsion
Examining child with refusal to weight-bear or limp
- General appearance, vitals/Temp, anemia, murmurs, rash.
- Gait
- Neurological
- Generalised lymphadenopathy (viral, hematological), look for focus of infections
- Excessive bruising, bruising in unusual (NAI, hematological)
- Abdomen, scrotum, inguinal
- Bony tenderness
- All joints
Knee can be from spine or hip
Include sacroiliac/spine
Scoliosis, lordosis
ROM
What conditions does bone scan show
- Osteomyelitis
- Discitis
- Perthes
- Occult fracture
What conditions does plain xray show
- Perthes/SUFE
- Chronic OM
- Tumors
- DDH
Specific causes of hip pain
- Transient synovitis
- Perthes disease
- SUFE
Hip externally rotates and shortened
Decreased internal rotation
Counselling in transient synovitis
- Most common cause of limp in children, also called irritable hip
- Inflammation of lining of the hip
- Cause is unknown, but may have had a recent viral illness
- Most commonly in those aged 3-10
- May have limp/difficulty crawling or standing
- Mild, usually gets better on its own, complete rest is all that’s needed. Starts to improve in 3 days, better in 2 weeks.
- If in pain can use paracetamol or NSAIDs
- Aspiring should not be give under the age of 16. Use ibuprofen catiously if history of asthma
- No tests or antibiotics required
- Encourage rest at home, no school until recovered. WIll walk in most comfortable way. Allow them to gradually do normal activties.
- See doctor if: fever, swelling, redness, persistent/increasing, not improving in 3 days or recovered in a week
Counselling about developmental dysplasia of the hip
- Abnormal development of hip joint
- Ball of hip not stable in socket, ligaments stretched/loose. Hips can dislocate and may not be obvious until walking.
- Stiff joint, different lengths, lean when standing, turning outward, uneven skin folds on buttock
- Mums hormones which loosen ligaments can get into baby’s bloodstream and loosen, the way they lie in utero, girls, first born, breech, family history
- Treatment may involve splints (Pavlik harness, for several months), closed reduction (move into correct position, hip spica plaster), open reduction- small cut in groin, with hip spica (plaster cast), osteotomy- when diagnosed late
- Staying in hospital
Splint, bracing, havlick->OPD
Closed/open->anaesthetic and hspital 1-3 days
Pain relief: panadol, morphine
Observed, examined frequently checking blood flow
Xray, MRI, CT done
Education to look after
Bring pram, car seat - Care, pain relief
- F/U MRI, CT
- Wound checked every 7-14 days
- 6 wekk r/v, plaster changed
- Regular xrays until has stopped growing
- Information can be found on RCH kids health informatio
What is hip spica
- Plaster from ankles to belly button
Historical features important if considering ricketts
- Bowing of legs
- Onset of walking->progression
- Symptoms now
- Limitation on activity
- Evidence of malabsorption
- Exposure outside
