Paraplegics whose range of motion is limited by para-osteo-arthropathy (POA) may have difficulty in becoming independent unless the heterotopic bone mass is removed. The recurrence rate is high if the bony mass is not mature at the time of surgery. Radiography and alkaline phosphatase correlations are not trustworthy. In 3 paraplegics with POA, radiolabeled osteotropic agents demonstrated a steady decrease in the uptake ratio (heterotopic/normal bone) followed by a steady-state plateau, reflecting the most useful index of maturation and allowing surgical removal of bone without recurrence.
因异位骨病（POA）导致活动范围受限的截瘫患者，除非切除异位骨块，否则可能难以实现自理。如果手术时骨块未成熟，复发率会很高。X线摄影和碱性磷酸酶之间的相关性并不可靠。在3例患有POA的截瘫患者中，放射性标记的亲骨剂显示摄取率（异位骨/正常骨）稳步下降，随后达到稳态平台期，这反映了最有用的成熟指标，并允许在无复发的情况下手术切除骨头。
