关于椎体压缩性骨折小关节损伤的临床研究

A Clinical Study of Trauma of Facet Joint in Compression Fracture of Vertebra

对椎体压缩性骨折,以往用静卧硬板床的方法处理,病程长,后遗症多,治疗中忽视了脊柱小关节的损伤,以及小关节的治疗对稳定脊柱的作用,生物力学测定椎体压缩骨折时受到5000～8000N的压力,而小关节关节囊所能承受的最大力为600N,计算得知,椎体骨折时,小关节受到远远超过其承受能力的压力(约为1400～2440N)可见它的损伤是不可避免的,几年来我们根据生物力学的原理,摸索总结出一套以优先治疗小关节损伤为主的独特的治疗方法,治疗83例病人,取得了成功,并大大缩短了病程,减轻了病人的痛苦,并避免了许多后遗症。

Compression fracture of vertebra is one of the most common fractures of spinal column. Jn previous practice of keeping the patient lying on hard bed steadily had a long duration of treatment and many sequelae and neglected both theoretically and therapeutically the facet joint damage and the contribution of treatment of facet joint to the stabilization of spinal column. According to biomechan-ical test, vertebra will break under a pressure of 5000-8000 N, however, facet joint capsula is able to sustain a 600 N pressure. With vertebra fracture, the facet joint will bear pressure far exceeding it's capacity (about 1400-2400 N). It is apparent that injury to the facet joint is inevitable. Based on bio-mechanical principle, we have developed a unique therapeutic system with priority given to the treatment of damage facet joint. For years, a series of 83 patients with facet joint injury in compression fracture of vertebra who received this new therapeutical system were all cured with their disease course greatly shortened, pains relieved and sequelae avoided.
