Kyphoplasty versus Vertebroplasty to Increase Vertebral Body Height: A Cadaveric Study

Abstract

Kyphoplasty increased vertebral body height more than vertebroplasty in this model of acutely created fractures in fresh cadaver specimens.

Kyphoplasty and Vertebroplasty Produce the Same Degree of Height Restoration

“…We saw improvements in vertebral body height of 1.5 and 1.4 mm and improvements in wedge angle of 3.0 and 2.7°with kyphoplasty and vertebroplasty, respectively. In a previous study on cadaveric material, Hiwatashi et al 31 showed kyphoplasty to restore vertebral body height slightly better than vertebroplasty (93% vs 82%). Other authors have also reported a greater height restoration in kyphoplasty than in vertebroplasty.…”

“…[11][12][13][14][15] Kyphoplasty is an alternative minimally invasive interventional method to vertebroplasty in which expandable balloons are used to restore height and to create a void in the central portion of a vertebral body before cement injection. [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] An experimental study on cadaveric material has shown better height restoration with kyphoplasty than with vertebroplasty. 16,31 However, only a few clinical studies have compared the 2 techniques.…”

Conversion to hypertrophic vertebral pseudarthrosis following percutaneous vertebroplasty

“…The wedge angle of the vertebra was measured in lateral radiographs taken in the sitting position [16]. Radiographic remodeling was evaluated by serial anteroposterior and lateral (decubitus position) radiographs taken every 2-3 months during the postoperative follow-up.…”

Factors Confluencing the Result of Percutaneous Balloon Kyphoplasty in Osteoporotic Thoracolumbar Compression Fracture

“…이에 대해 여러 가지 수술적 요법이 환자의 연령 및 외상의 정도에 따라 시 행되고 있다. 그 중에서도 외상의 기전이나 정도가 심각하지 않은 골다공증성 흉요추 골절의 수술적 치료로는 앞서 언급 된 경피적 척추 성형술과 경피적 풍선 척추 성형술이 안전하 고 만족스런 수술법으로서, 보편적으로 시행되고 있다 4,5,[10][11][12] . 기존의 골다공증성 흉요추 압박골절의 치료에 시행되던 척 추성형술은 동통을 감소시키고 추체의 기계적 강도를 증가 시켜 함몰이 심화되는 것을 막을 수는 있으나, 후만변형을 효 과적으로 호전 및 예방할 수 없고, 시멘트가 추체외로 유출되 어 혈관색전 또는 신경손상 등의 문제를 야기할 수 있다 17,18) .…”
