We applied joint distraction using an Ilizarov apparatus in 11 patients with post-traumatic osteoarthritis of the ankle to try to delay the need for an arthrodesis. Distraction for three months resulted in clinical improvement in pain and mobility for a mean of two years, with an increase in the joint space. We considered that these effects may be produced by the absence of mechanical stress on the cartilage combined with the intra-articular hydrostatic pressures during distraction. We measured these pressures during walking with distraction, and found levels very similar to those reported to improve osteoarthritic cartilage when applied in vitro.
我们对11例创伤后踝骨关节炎患者应用伊利扎罗夫器械进行关节牵张，试图延缓关节融合术的需求。三个月的牵张使疼痛和活动度得到临床改善，平均持续两年，关节间隙增加。我们认为这些效果可能是由于牵张过程中软骨上没有机械应力，同时关节内存在流体静压所致。我们在牵张状态下行走时测量了这些压力，发现其水平与体外应用时据报道可改善骨关节炎软骨的压力水平非常相似。
