Insights
Septic arthritis (SA) in children requires prompt treatment. This review found no significant differences in outcomes between arthrocentesis, arthrotomy, and arthroscopy for pediatric SA, suggesting technique choice depends on the surgeon.
Area of Science:
- Pediatric Orthopedics
- Surgical Innovation
- Evidence-Based Medicine
Background:
- Septic arthritis (SA) in children is a joint inflammation that can necessitate emergency surgery.
- The incidence of pediatric SA in Europe ranges from 2-7 per 100,000 children.
- Prompt treatment is crucial to prevent severe complications.
Purpose of the Study:
- To systematically review and compare the effectiveness of arthrocentesis, arthrotomy, and arthroscopy for treating pediatric septic arthritis.
- To provide guidance on the optimal timing and selection of surgical interventions for pediatric SA.
Main Methods:
- A systematic review was conducted using PubMed, ScienceDirect, and MEDLINE databases.
- Studies of any evidence level reporting surgical outcomes for pediatric SA were included.
- Findings were evaluated by three independent authors and approved by two senior investigators.
Main Results:
- Analysis of 24 selected articles revealed no statistically significant differences in clinical or radiographic outcomes among the surgical techniques.
- The literature does not support one surgical method over others for pediatric septic arthritis based on numerical outcomes.
- The choice of surgical technique appears to be operator-dependent.
Conclusions:
- An algorithm for suspected septic arthritis in children was developed.
- The selection of surgical intervention for pediatric SA should consider surgeon preference and expertise.
- Further research may be needed to identify specific patient factors influencing optimal surgical technique selection.
Background:
Septic arthritis (SA) in children is an acute inflammatory disease of the joints. If not treated promptly, it could become a surgical emergency. The incidence of the disease in children in Europe is approximately 2-7 per 100,000 children. The aim of this systematic review was to investigate which of these treatments-arthrocentesis, arthrotomy, and arthroscopy-provides better results in children and when to use them.
Methods:
Three independent authors conducted a systematic review of PubMed, ScienceDirect, and MEDLINE databases to assess studies with any level of evidence that reported the surgical outcome of SA. Two senior investigators evaluated and approved each stage's findings.
Results:
A total of 488 articles were found. After screening, we chose 24 articles that were suitable for full-text reading based on the inclusion and exclusion criteria. The results of our analysis showed that there are no numerically significant differences reported in the literature on clinical and radiographic outcomes by surgical technique.
Conclusions:
We developed an algorithm that could be used if septic arthritis is suspected. Based on our results, the surgical technique to be used will depend on the operator who will perform it.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
