We present the largest series of paediatric pelvic pyomyositis from a temperate country, analyse the factors influencing long term prognosis and suggest a diagnostic protocol. ⋯ There is an increasing occurrence of this tropical disease in temperate countries. Early diagnosis with an MRI scan and early antibiotic use results in good outcomes.

Observational Study
Hyaluronic acid injections for osteoarthritis of the knee: predictors of successful treatment.
This study aimed to identify patient and treatment factors that predict a favourable response to intra-articular hyaluronic acid (HA) treatment to better guide patient and treatment selection. ⋯ Patients with mild-to-moderate osteoarthritis (grades 1-2) and those responding positively to the first injection were twice as likely to respond positively to the injection series, as were patients ≥60 years. Patients who did not respond positively were more likely to proceed to arthroplasty. The VAS appears to be a reliable method of defining and monitoring treatment success. Judicious patient selection and counseling may improve outcomes associated with intra-articular HA injections.

The aim of this study was to compare the fixation power of sacroiliac rod fixation (SIRF), which was developed based on our original "within ring" concept to exclude the lumbar vertebra from the fixation range, and spinopelvic fixation (SPF) in a biomechanical experiment. ⋯ In biomechanics experiments, vertical resistance was stronger in SPF-treated than SIRF-treated bone, but stiffness and deformation, horizontal resistance, and angular deformity did not differ significantly.

Randomized Controlled Trial
The efficacy and safety of two low-dose peri-operative dexamethasone on pain and recovery following total hip arthroplasty: a randomized controlled trial.
To evalute the efficacy and safety of two low-dose peri-operative dexamethasone on pain and recovery following total hip arthroplasty (THA). ⋯ I.

We aimed to investigate the status quo of orthopaedic publications from China and characterize the most-cited articles to provide valuable insights for orthopaedists. ⋯ The Chinese orthopaedic research grew rapidly in terms of number of publications in the last decades, and the quality of publications also improved in recent years.
