In order to determine the extent of cervical spine immobilization provided by the thermoplastic Minerva body jacket (TMBJ) 20 healthy male subjects underwent analysis of cervical spine motion before and after TMBJ placement. Maximal cervical flexion/extension and lateral bending were measured from lateral and anteroposterior roentgenograms, respectively. Maximal cervical rotation was measured from overhead photographs. The TMBJ significantly limited flexion/extension at each level of the cervical spine, as well as rotation and lateral bending (P less than 0.001). Flexion/extension at each cervical level was found to be equal to that allowed by the halo with body jacket at most levels and less at the occiput-C1, C3-C4, and C6-C7 (as reported in studies using similar methodology). The present study suggest that the thermoplastic Minerva body jacket is a valuable option for rigid external immobilization of the cervical spine.
为了确定热塑性密涅瓦身体夹克（TMBJ）对颈椎的固定程度，20名健康男性受试者在佩戴TMBJ前后接受了颈椎活动度分析。分别从侧位和前后位X线片测量最大颈椎屈伸和侧屈。从头顶照片测量最大颈椎旋转。TMBJ显著限制了颈椎各节段的屈伸以及旋转和侧屈（P<0.001）。发现每个颈椎节段的屈伸在大多数节段与头环加身体夹克允许的屈伸程度相当，而在枕骨-C1、C3-C4和C6-C7节段则较小（如使用类似方法的研究所报道）。本研究表明，热塑性密涅瓦身体夹克是颈椎刚性外固定的一个有价值的选择。
