作者们指出,当前为预防关节强直术后复发,一些学者用肌肉、脂肪、皮肤、软骨等,或金属帽,或丙烯酸酯塑料帽、或费拉托夫氏皮管作填塞物。另些学者则反对用任何填塞物,理由是有的组织本身即可形成瘢痕,有的则于其周围发生瘢痕。这样均可促进关节强直的复发。现在还有的学者主张用浓硝酸银腐蚀锯断的骨创。然而,所有这些方法,都不能预防复发和下颌骨畸形。 The authors point out that currently some researchers use muscle, fat, skin, cartilage, etc., or metal caps, or acrylate plastic caps, or Feratov skin tubes as a tamponade to prevent recurrence after ankylosing spondylitis. Other scholars opposed the use of any tampons on the grounds that some organizations can form scars on their own, while others scar around them. This can promote the recurrence of ankylosis. There are still scholars advocating the use of concentrated nitric acid silver saw cut bone wound. However, none of these methods prevent relapse and mandibular deformity.
