The correct diagnosis is transient synovitis. The child was discharged home on ibuprofen with planned follow-up the next day, and clear instructions to return if there was any worsening.
Transient synovitis is a self-limited disease with no expected long-term complications. It tends to occur in children between 2- and 9-years-old.
Typically, the patient will complain of hip pain on one side and exhibit a limp. Thigh pain, knee pain, and low-grade fever (<101 degrees F) may also be present.
As indicated on the previous page, appropriate steps for the clinician to take upon presentation include WBC, ESR, x-ray, and ultrasound.
Pain most often resolves within 10 days or less. Treatment may include limiting the child’s activity to make him or her more comfortable. However, there is no danger associated with performing normal activities. Nonsteroidal anti-inflammatory medications may be prescribed to reduce pain.
