STUDY DESIGN: A retrospective study. PURPOSE
To compare the level of restoration of the vertebral height, improvement in the wedge and kyphotic angles, and the incidence of complications in osteoporotic compression fracture in patients treated with either kyphoplasty or lordoplasty. OVERVIEW OF LITERATURE: Kyphoplasty involves recompression of the vertebral bodies. Recently, a more effective method known as lordoplasty was introduced.
Between 2004 and 2009, patients with osteoporotic thoracolumbar vertebral compression fractures were treated by either kyphoplasty (n = 24) or lordoplasty (n = 12) using polymethylmethacrylate (PMMA) cement, and the results of the two interventions were compared. A visual analogue scale was used to measure the pain status. Preoperative and postoperative radiographs were analyzed to quantify the anterior vertebral height restoration and the wedge and kyphotic alignment correction.
All patients in both groups reported a significant decrease in pain. The anterior heights increased 24.2% and 17.5% after the lordoplasty and kyphoplasty procedures, respectively (p < 0.05). Three months after the procedures, there was a larger decrease in the loss of anterior vertebral height in the kyphoplasty group (12.8%) than in the lordoplasty group (6.3%, p < 0.05). The wedge angles decreased after both procedures. The wedge angle in the lordoplasty group maintained its value after 3 months (p < 0.05). The kyphotic angular correction was 11.4 and 7.0degrees in the lordoplasty and kyphoplasty groups, respectively (p < 0.05). Both kyphotic deformities worsened to a similar degree of 5degrees after 3 months.
Lordoplasty is more useful than kyphoplasty in terms of the improved anatomic restoration and postoperative maintenance.
