背景:骨粗鬆症性椎体骨折の遷延癒合や骨癒合不全の治療法は確立していない.
方法:2000年から253例をJewett型硬性コルセットを用いて保存的に加療し,1年間以上前向きに調査検討した.16例が椎体内にvacuum cleftを有する遷延癒合か骨癒合不全となったが,コルセットを平均17.8カ月間装着し治療を継続した.
結果:腰痛は平均12カ月で消失し,vacuum cleftは受傷後平均22カ月で消失した.骨癒合は隣接椎体との仮骨架橋癒合・骨橋によって受傷後平均20.7カ月で完成した.後弯変形は平均36.4°であったが全例受傷前と同様のADLを獲得できた.
結論:骨粗鬆症性椎体骨折は重篤な神経障害がない限り保存的に治療すべきである.
Background:The treatment of delayed or nonunion osteoporotic vertebral fractures (OVFs) is still controversial.
Methods:This study looked at 253 patients (318 vertebral fractures) of OVFs over a 13 year period from 2000 prospectively. All patients were treated with conservative measures using Jewett Corsets. The sixteen cases developed into delayed or non-union with vacuum cleft in the vertebral body. We had continued with the same Jewett Corset treatment for between 5−88 months (mean 17.8 months).
Outcome:Lower back pain improved completely after 7−25 months (mean 12 months). Vacuum clefts in the vertebral bodies disappeared 7-88 months (mean. 22 months). Bony union in the fractures sites were achieved with bony bridging calluses from the adjacent injured vertebral end plate between 8−88 months (mean. 20.7months) after injury.
Conclusion:All patients achieved the same ADL as before their injuries without any severe side effects or complaints, therefore OVFs without severe nerve disorders should be treated conservatively.
