Balloon Kyphoplasty for Intractable Pain in Pediatric Vertebral Fracture

By Ryan Goodwin, MD; David P. Gurd, MD; Rabi Hanna, MD; and Thomas E. Kuivila, MD

Osteopenia and osteoporosis are common side effects of both steroid use and chemotherapy in children and adults. Both conditions can potentially lead to vertebral compression fractures. Vertebral compression fractures can be a significant source of debilitating pain, psychosocial decline and physical impairment in patients of all ages.

Vertebroplasty and balloon kyphoplasty are percutaneous vertebral augmentation techniques that have been used extensively with good to excellent results in adults to control pain following vertebral compression fractures. To date, their use in children has been limited, and few studies and no formal indications exist.

A review of three patients

We retrospectively reviewed outcomes for three pediatric patients who underwent balloon kyphoplasty at our institution to address their intractable pain from vertebral compression fractures between 2007 and 2013. Our results were published in the Journal of Pediatric Othopaedics.

The underlying diagnoses for these patients (average age 12.3 years, all male) were:

• metastatic alveolar rhabdomyosarcoma
• abdominal desmoplastic small round cell tumor
• IPEX-like (immune dysregulation, polyendrocrinopathy, enteropathy, X-linked) syndrome

Preoperative pain scores were very severe (8 to 9 on a 10-point scale), impacting the children’s ability to independently ambulate. One patient even required elective intubation due to respiratory distress secondary to pain. Two of the three patients underwent multilevel procedures.

Postprocedure pain levels

At an average of 3.6 weeks postsurgery, patient pain was improved to an average of 2/10. Two of the three patients were able to sit, stand and walk independently at follow-up. The third patient (with IPEX-like syndrome) was successfully extubated one-week postoperatively. He was capable of normal activity, including playing basketball, at follow-up about two years after balloon kyphoplasty treatment. No complications were encountered in this small case series.

Our follow-up was short in two of the three patients because of their early demise due to underlying oncological disease.

In our series, balloon kyphoplasty dramatically decreased pain and increased function in the immediate postoperative period in each of the patients treated. This small study provides initial information on the usefulness and safety of this procedure in this subset of seriously ill patients.Further research is necessary to establish indications for balloon kyphoplasty in pediatric patients.

Figure 1A. A 13-year-old male with IPEX-like syndrome presented with severe thoracic and lumbar back pain in the setting of prolonged high-dose steroid use. Numerous vertebral compression fractures in the lower thoracic and upper lumbar regions were identified. The patient was electively intubated due to respiratory distress, thought to be related to his refractory pain.

Figure 1B. The patient underwent four-level balloon kyphoplasty in two stages, separated by one week. His kyphotic deformity and pain improved dramatically postoperatively, allowing him to sit without pain within one month and walk independently within two months.
