New study aims to unmask hidden causes of childhood joint stiffness
NCT ID NCT07173010
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study will look at 35 children with joint problems that are not caused by inflammation, such as stiffness or deformity. Researchers will use exams, lab tests, and imaging to find the true cause, which could be rare genetic conditions like mucopolysaccharidoses or osteogenesis imperfecta. The goal is to improve diagnosis and prevent children from being treated incorrectly for inflammatory arthritis.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help doctors better diagnose rare joint conditions in children and avoid giving them unnecessary treatments meant for inflammatory arthritis.
- What could go wrong
- This is a small, early observational study at a single hospital, so findings may not apply to all children. It aims to gather knowledge, not test a new treatment.

Who is studied
The study will include all pediatric patients presented with non inflammatory arthropathy based on clinical manifestations, laboratory investigations and imaging up to age of 18 years in the last 3 years (retrospective) and those who will present newly through a duration of one year (preospective). They will be recruited from the inpatient and outpatient clinic of Allergy, Immunology and Rheumatology department at Assuit University Children's hospital.
