经皮椎体后凸成形术联合骨填充网袋成形术治疗单节段胸腰椎骨折OA

Objective To investigate the efficacy of percutaneous kyphoplasty(PKP)combined with bone-filling mesh bag plasty for treating single-level thoracolumbar fracture.Methods The 22 patients with single-level thoracolumbar fractures were treated using PKP combined with bone-filling mesh bag plasty.Operation time,intraoperative blood loss,volume of bone cement injected,incidence of complications,pain VAS,kyphotic Cobb angle,ODI score,and ver-tebral height percentage were recorded.Results All patients were followed up for 3 months.The intraoperative blood loss was 2-10(5.40±2.15)ml,operation time was 25-44(36.81±5.62)min and volume of bone cement injected was 4.5-7.1(5.98±0.66)ml.The bone cement leakage occurred in one case of intervertebral space during the op-eration;there were no postoperative complications such as nerve damage,pulmonary embolism,or cerebral infarction.Three months after surgery,the pain VAS,kyphotic Cobb angle,and ODI score were all lower than before surgery(P＜0.05);the percentage of height of the anterior edge,posterior edge,lateral edge(mean value of left and right sides)of the injured vertebrae were higher than before surgery(P＜0.05),and the patient's pain and discomfort in the thraco-lumbar regions had significantly improved,compared to the preoperative levels,with good function of the injured ver-tebrae.Conclusions Percutaneous kyphoplasty combined with bone-filling mesh bag plasty for treating single-level thoracolumbar fracture has the advantages of minimally invasive,low intraoperative bleeding,short surgical time,effec-tive reduction of bone cement leakage,pain relief,and improvement of kyphosis deformity.
