Laminectomy: effects on postoperative technetium and gallium scintigraphy.
Bone scans using Tc-99m diphosphonate were found to become abnormal within 2 weeks after laminectomy in less than half of patients regardless of the extent of the operation. The degree of new uptake equaled that of the sacroiliac joints in only one of 19 patients with a normal preoperative scan. However, the Ga-67 citrate scan usually became abnormal (89%) postoperatively. Thus the Tc-99m bone scan may be helpful in detecting postoperative infection.
