In a single centre over two years, four children (7 to 10 years old) with upper limb osteosarcoma underwent chemotherapy followed by forequarter amputation. All patients had preoperative pain and were treated with gabapentin. Nerve sheath catheters were placed in the brachial plexus intraoperatively and left in situ for five to 14 days. After surgery, all patients received local anaesthetic infused via nerve sheath catheters as part of a multimodal analgesia technique. Three of the four patients were successfully treated as outpatients with the nerve sheath catheters in situ. All four children experienced phantom limb pain; however, it did not persist beyond four weeks in any patient.
