RESUMO

OBJECTIVE: To develop a clinical decision guide for the diagnosis and treatment of hyperextension injuries of long fingers. STUDY DESIGN: Consecutive patients age <16 years (n = 300) with an acute proximal interphalangeal (PIP) joint hyperextension injury were included. High-risk and low-risk measures for severe injury were established with a standardized clinical examination and anteroposterior and lateral radiographs of the injured finger. Four clinical variables were assessed: location of pain; swelling and bruising, stability, and mobility. Pathological radiographic findings were compiled, and the risk of late complications was analyzed. The predictive value of the clinical examination in the identification of low-risk injuries was assessed. RESULTS: The majority (67%) of children consulting for a hyperextension finger trauma did not have a fracture. No child with a low-risk clinical examination had a subsequent high-risk diagnosis (eg, relevant intra-articular fracture, dislocation). Among 64 clinical high-risk diagnoses only 12 significant fractures were found. CONCLUSION: Treatment decisions after PIP hyperextension injuries can be based on a clinical examination using a standardized evaluation protocol. Application of the clinical decision guide presented here has a sensitivity of 100% to rule out a significant injury. Present results showed that the majority of radiographs currently performed are avoidable. Once the decision rule is validated, its clinical application will improve patient care, reduce waiting times in emergency departments, avoid unnecessary radiation exposure, and possibly reduce costs.

RESUMO

OBJECTIVES: To assess the contemporary bacteriologic epidemiology of pediatric osteoarticular infection with particular regard to children's ages, because Kingella kingae has gained increasing recognition as the predominant pathogen for osteoarticular infection in young children. STUDY DESIGN: Retrospective file review of enrolled children from 0 to 15 years of age, admitted to our institution from 2007 to 2015 for suspected osteoarticular infection (217 cases). Information on age, sex, the bone or joint infected, imaging studies, and laboratory data (including bacterial investigations) were collected for analysis. RESULTS: Microorganism identification was possible for 138 infected children (63.6%), through blood (cultures or polymerase chain reaction [PCR]) and/or operative samples (cultures or PCR). Thirty-one patients (14.3%) were found to both have positive blood cultures and operative samples. The results of positive bacteriology specimens identified the most common causative pathogen for osteoarticular infection as K kingae (47.8% of microbiologically confirmed osteoarticular infections of all ages, and 87.7% in children between the ages of 6 and 48 months), significantly more common than Staphylococcus aureus (35.5% of microbiologically confirmed osteoarticular infections of all ages, and 78.2% in children >4 years of age). CONCLUSIONS: Use of the appropriate PCR assays demonstrated that K kingae currently is the major bacterial cause of pediatric osteoarticular infection, especially in children <4 years of age in whom K kingae is more common than S aureus. PCR assays should be used in routine microbiologic laboratory evaluation to improve diagnostic performance. However, despite the use of molecular methods, there are many osteoarticular infections in which no microorganism is detected, which suggests that these infections may be caused by other as yet unrecognized fastidious microorganisms.
