Aims: To determine the usefulness of isotope bone scintography in investigating skeletal pain in children. Methods: We reviewed bone scans, notes and radiographs requested for children under 16 years presenting to two teaching hospitals in the city. Results: There were 229 patients with and average age of 11 years.

139 were investigated for back pain and 90 for skeletal pain in the appendicular skeleton.

There were positive scans in 13 patients with back pain and 22 with pain elsewhere.

The management was altered in only 3 children with back pain and 6 with other skeletal pain. Conclusions: Isotope bone scintigraphy is a low yield, and non-speciþc investigation that imparts a signiþcant dose of radiation. Its role in the investigation of skeletal pain should be re-evaluated.

To determine the usefulness of isotope bone scintigraphy in investigating skeletal pain in children, we reviewed the bone scans, plain radiographs and clinical notes of consecutive children under 16 years of age presenting to children’s orthopaedic surgeons at two teaching hospitals in one city.

There were 229 patients, of which 87 were boys and 142 girls. They had an average age of 11 years. 139 were investigated for back pain and 90 for skeletal pain in the appendicular skeleton. They were investigated for a variety of conditions including idiopathic back and skeletal pain, scoliosis, Scheuermann’s disease, spondylolysis, osteomyelitis and postoperative pain.

There were positive scans in 4 out of 78 patients with idiopathic back pain, and 13 out of 64 with idiopathic skeletal pain.

Overall the positive scan rate for all conditions was 10% for back conditions and 22% for pain in the appendicular skeleton.

Of all patients with back pain the management was altered in only 3 children. Of all those investigated for appendicular skeletal pain, the management was altered in 6 children. Isotope bone scanning is a low yield and non-specific investigation that imparts a significant dose of radiation to the patient.

It should not be used as a first line investigation for idiopathic back or skeletal pain in children. Other tools such as MRI should be considered initially.

It still has a role in the investigation of children with obvious abnormality on radiographs, with spondylolysis and probably where there are worrying clinical features to the pain such as night pain and recent onset.

The role of bone scanning in the investigation of skeletal pain should be re-evaluated in the investigation of skeletal pain.

We undertook a review of bone scans requested for children to determine the usefulness of isotope bone scintigraphy in investigating skeletal pain in this population.

We reviewed the bone scans, plain radiographs and clinical notes of consecutive children under 16 years of age presenting to children’s orthopaedic surgeons at two teaching hospitals in one city.

There were 229 patients, of which 40% were boys and 60% girls. They had and average age of 11 years. 139 were investigated for back pain and 90 for skeletal pain in the appendicular skeleton. They were investigated for a variety of conditions including idiopathic back and skeletal pain, scoliosis, Scheuermann’s disease, spondylolysis and stress fractures, osteomyelitis and post-operative pain.

There were positive scans in 4 out of 78 patients with idiopathic back pain, 1 of 25 patients with scoliosis and 1 out of 5 with spondylolysis and 11 out of 70 with idiopathic skeletal pain.

Of all patients with back pain the management was altered in only 3 children. Of all those investigated for appendicular skeletal pain the management was altered in 6 children.

Conclusion: Isotope bone scanning is a low yield, and non-specific investigation that imparts a significant dose of radiation to the patient. It should not be used as a first line investigation for idiopathic back or skeletal pain in children. Other tools such as MRI should be considered initially.

The role of isotope bone scanning in the investigation of skeletal and joint pain in children should be reevaluated.
