Summary
OBJECTIVE: To retrospectively analyze the medical information of 17 sufferers with bone cement leakage after percutaneous kyphoplasty and discover the leakage sort and mid-term medical results.
METHODS: The medical information of 17 sufferers with osteoporotic vertebral compression fractures occurred bone cement leakage after percutaneous kyphoplasty from October 2011 to October 2016 had been collected. There have been 7 males and 10 females, aged from 68 to 87 years previous with a median of 78 years. All of the sufferers had the historical past of low emergy trauma who had regular exercise and full self-care for dwelling earlier than trauma, and complained with the decrease again ache with out indicators and signs of nerve root harm after trauma. In accordance with the anatomical location by pictures, the bone cement leakage pathways was confirmed, the preoperative and postoperative vertebral physique peak and Cobb angle had been measured, the advance of spinal stenosis had been recorded. Preoperative and postoperative visible analogue scale (VAS) and Oswestry Incapacity Index(ODI) had been used to judge ache and each day actions.
RESULTS: All of the sufferers had been adopted up for four to 7 years with a median of 5.1 years. In accordance with anatomical location by pictures, we discovered the bone cement leakage pathways of vertebral facet sort in 6 circumstances, intervertebral disc sort in three circumstances, spinal canal sort in 2 circumstances, vertebral pedicle sort in 5 circumstances and combined sort in 1 case. Vertebral physique peak from preoperative(27.7±three.5)% restored to (56.four±2.5)% at remaining follow-up, and the kyphosis was corrected with Cobb angle from preoperative(45.three±four.2)° corrected to(18.three±three.1)° at remaining follow-up. VAS rating decreased from preoperative 7.9±1.5 to 2.1±zero.5 at remaining follow-up. ODI clearly restored from preoperative(49.1±7.5)% to (23.5±three.7)% at remaining follow-up. The nerve signs in decrease limbs occurred in 2 circumstances, and the neurological symptom was disappeared after pressing symptomatic therapy and anaphase trophic nerve treating. Decrease again ache occurred in three circumstances, together with one case of insufferable ache, and the ache disappeared after symptomatic therapy.
CONCLUSIONS: Though the speed of bone cement leakage throughout percutaneous vertebral kyphoplasty is just not low, the bone cement leakage has little affect on PKP surgical procedure. Even when a bit of leakage occurred throughout the spinal canal through the surgical procedure, spinal canal decompression won’t be wanted urgently. The numerous medical signs brought on by leakage can mainly disappear after therapy in mid-term follow-up.
