Differential Diagnoses? Labs/Imaging? Labs CBC w/Diff – WBC 15.0 G 71.1 L 13.0 M 14.0 E 1.5 B 0.4 ESR 74 (NML 0-10) CRP 32 (NML 0-0.8) – Hb 12.3 – Hct 35.9 – Plt 369 Imaging Left Hip X-Ray – Widened left hip joint superiorly. No evidence of fracture. Left Hip US – Increased fluid present in left hip joint. Consults Orthopedics – Evaluated patient and diagnosed with septic hip vs. transient synovitis Septic Hip vs Transient Synovitis Septic Hip vs Transient Synovitis To minimize tension: - Flexed Abducted Externally rotated *Both may present this way* Why do we care? Prognosis! If left untreated: – Septic Arthritis (Bacterial) Dislocation, subluxation, coxa vara/breva (defects of ossification of the femoral neck), absence of head & neck of femur, degenerative (postinfectious) arthritis, leg length discrepancy (3-4 inch). Complete destruction of the hip joint. Limited course, no treatment required! Full recovery. May develop Legg-Calve-Perthes Disease in ~2 years. – Relationship unclear – Transient Synovitis (Viral, probably) **WE DON’T WANT TO CONFUSE THESE TWO!!! Pathogenesis Septic Arthritis: – Osteomyelitis of the femoral neck Synovial Membrane – Bacteremia – Faulty Femoral Culture – Septic Organisms: >50% of neonates; 20% of infants Why? Staph Aureus > Streptococcus Rarely: Neisseria meningitidis, Kingella kingae, Pseudomonas aeurginosa Transient Arthritis: – Toxic Post traumatic event or URI; Viral etiology suspected MOST common cause of hip pain in children <10 y/o other joints also involved – Rheumatoid The Matchup (Diagnosis) Septic Arthritis – – – – – – – – – – – Rapid Onset (24 hr) Acutely ill Refuses to bear weight Fever Leukocytosis Elevated ESR Xray: widened joint space as a result of swelling Bone Scan: undetected initially Ultrasound: fluid present More common: M < 3yo Joint aspirate: + BACTERIA Transient Synovitis – Child appears well – Painful limp; referred to inner thigh/knee joint. – MILD fever – MILD leukocytosis – MILD ESR elevation – Xray: widened joint space as a result of swelling – Ultrasound: fluid present – More common: age 4-8 – Joint aspirate: increased WBC (especially PMN’s); Gram stain - ; Culture - except hip Septic Hip: Kocher Criteria (For CHILD with painful hip) 4 Criteria – – – – Non-weight bearing on affected side ESR >40 mm/hr Fever WBC >12,000 If 4/4 criteria met: 99% chance of septic arthritis If ¾ criteria met: 93% chance of septic arthritis If 2/4 criteria met: 40% chance of septic arthritis If ¼ criteria met: 3% chance of septic arthritis Now do joint aspiration: Bacteria = Septic Joint! Septic Arthritis Treatment: Emergency – I&D of joint – IV antibiotics Direct sterilization of joint with antibiotics – Weight-bearing as tolerated – Pain relief with anti-inflammatory agent (Ibuprofen) Anti-Staph agent should be used for presumed S. Aureus Culture and susceptibility should be followed to guarantee treatment efficacy Follow ESR: persistently elevated levels indicate continued activity of disease process Total duration of IV Antibiotics up to 3-6 weeks Transient Synovitis Treatment: – Bed Rest and Symptomatic Care Anti-inflammatory (Ibuprofen) Improvement in 24 hours – Motion restored in 2-4 days – Crutches X 2-4 weeks – Observe patient X 2 years watch for Legg-Calve-Perthes Disease Hospital Course Due to patient being admitted on the weekend, there was no conscious sedation team. Patient was taken to OR for aspiration of left hip. Ortho aspirated 8-10cc of pus from the left joint. Cultures sent for identification/sensitivity – 2+ Staph Aureus, Methicillin resistant; Sensitive to Clindamycin IV Clindamycin given 140mg Q8H X 14 days. Patient had PICC line placed so antibiotics could be administered at home. Followup with Orthopedics 1 week after d/c.
