Aims

We aimed to describe the epidemiological, biological, and bacteriological characteristics of osteoarticular infections (OAIs) caused by Kingella kingae.

Methods

The medical charts of all children presenting with OAIs to our institution over a 13-year period (January 2007 to December 2019) were reviewed. Among these patients, we extracted those which presented an OAI caused by K. kingae and their epidemiological data, biological results, and bacteriological aetiologies were assessed.

Aims

This multicentre, retrospective study aimed to improve our knowledge of primary pyogenic spinal infections in children by analyzing a large consecutive case series.

Patients and Methods

The medical records of children with such an infection, treated at four tertiary institutions between 2004 and 2014, were analyzed retrospectively. Epidemiological, clinical, paraclinical, radiological, and microbiological data were evaluated. There were 103 children, of whom 79 (76.7%) were aged between six months and four years.

Introduction: Evaluation of acute hip pain in children can be challenging, because there are several diagnoses to consider. Most patients have a transient synovitis of the hip, which is a benign and self-limited condition. However, its similarities with other more serious disease make the diagnosis one of exclusion. In the Children’s Hospital of Geneva, children presenting with an acute hip pain are treated according to a specific screening protocol including blood sample with rheumatoid panel, hip ultrasound, and conventional X-rays. The objective of our study were to assess the efficacy of the screening protocol on the final diagnosis. We also provided a better characterization of transient synovitis of the hip.

Methods: We retrospectively reviewed the medical records of children who had the investigation’s protocol between 1999 and 2003.

Results: 269 medical records were reviewed comprising 66.2% of boys and 33.8% of girls, with a mean age of 5.5 years. Prior to presentation, 68.4% of children reported pain of < 24 hours in duration. Limp or refusal to bear weight was observed in all cases. According to the Kocher’s predictors of septic arthritis of the hip (fever, non weight-bearing, ESR > 40 mm/h, serum WBC count of > 12000 cells/mm3), 62% had zero predictor, 22% had one, 15% two, 1% three, and none four. A positive rheumatoid factor test was found in 18% of children, whereas 16% of patients had a positive antinuclear antibody test. During hospitalisation one child was diagnosed as having septic arthritis. The remaining patients were diagnosed by exclusion as having a transient synovitis of the hip since clinical follow-up was normal at 6 weeks.

Conclusion: Transient synovitis of the hip is a diagnosis of exclusion, and septic arthritis is the main condition to rule out. Using Kocher’s predictors of septic arthritis is useful for distinction between both conditions early at presentation. In our collective, only 3 patients with transient synovitis had a three of four predictors. Our study also showed that screening for a rheumatologic disease should not be done routinely at the first episode of hip pain. Indeed, positive tests were never confirmed with a clinical situation evocative of rheumatologic disease. More selective criteria should be used before doing a rheumatologic panel. Furthermore our work emphasizes the economical impact of a management of this frequent condition with less blood investigations.

Introduction: Mac Farland fracture is a joint fracture of the ankle in children, which involves the medial malleolus (Salter-Harris type III or IV) and is frequently associated with a fracture of the distal fibula. These injuries have a major risk of resulting in a medial epiphysiodesis bridge which, in turn, can lead to a varus deformity. As of today, recommended treatment for displacements wider than 2mm is open reduction with screw fixation. The aim of this study is to evaluate functional and radiological results of a new less invasive surgical procedure.

Materials and Methods: We retrospectively analyzed a case series of patients who suffered from a Mac Farland fracture and underwent percutaneous screw fixation with arthrographic control. Data collected for each child included age at diagnosis, gender, mechanism and side of injury, radiological Salter-Harris classification of medial and lateral malleolus fracture, size of the fracture line gap before and after treatment, and duration of cast immobilization. Results are given according to the classification by Gleizes (2000), based on clinical and radiological criteria: good, fair, and poor.

Results: There were twelve patients, five girls and seven boys, with a mean age of twelve years and six months (range: 10–15). Average follow-up was eighteen months (range: 9–57). Medial malleolus fracture was Salter-Harris type III in seven patients and type IV in five. The mean preoperative fracture line gap was 2.7mm (range: 2–4). All the patients underwent closed reduction and ankle arthrography to check for anatomical reposition. The fracture was then percutaneously fixed with two screws in nine patients and one screw in three. Duration of cast immobilization after surgery was forty-five days in average. At the time of last follow-up the functional and radiological results were good for all the patients according to Gleizes’ classification.

Conclusion: Closed reduction combined to ankle arthrography followed by percutaneous osteosynthesis is, in our opinion, an interesting less invasive surgical alternative to classic open reduction and internal fixation for displaced Mac Farland fractures.

A six-year-old girl sustained a Monteggia type-I equivalent fracture of the right forearm. We describe the method of treatment of this rare fracture and its outcome.
