Percutaneous kyphoplastyvia unilateral transverse process-pedicle approach under lateral position for os-teoporotic vertebral compression fracture / 实用医学杂志

ABSTRACT

Objective To explore the clinical efficacy of percutaneous kyphoplasty(PKP)via unilateral transverse process-pedicle approachunder lateral positionfor osteoporotic vertebral compression fracture(OVCF). Methods From January 2014 to January 2016,36 patients were divided into group A(n=17)receiving PKP un-der lateral position,and group B(n=19)receiving PKP under prone position.The surgical duration,blood loss, volume of cement injection,and rate of cement leakage were compared. Modified Kolcaba questionnaire was used for assessing the degree of comfortunder different position. The kyphotic angle,VAS score and anterior vertebral height compression ratio in pre-and post-operation were applied for assessment of surgical outcomes. Results All the patients received the procedures successfully under local anaesthesia with no serious complications including spinal cord injury. The surgical duration was(73.5 ± 23.4)min in group A and(44.7 ± 15.4)min in group B.The blood loss was(29.1 ± 16.9)mL and(15.7 ± 7.1)mL;and the comfort questionnaire score was(64.3 ± 17.9)and (43.7 ± 17.1),respectively.There were significant statistical differences between the two groups(P<0.05). There were no differences in cement injection,cement leakage,kyphotic angle,VAS score and anterior vertebral height compression ratio(P > 0.05). Conclusions PKP via unilateral transverse process-pedicle approach under lateral position is a safe and effective way for OVCF.But the surgical durationis longer in lateral position than in prone posi-tion due to the more difficult technique.PKP under lateral position may be an alternative approach for PKP.
