对颈椎小关节脱位进行了分析，其中冷冻切片与磁共振（MR）图像相关。在10具死亡时年龄为10-69岁的尸体的解剖切片中，定义了四种类型的半月板。1型是致密结缔组织的薄垫圈，覆盖50%或更多的关节间隙。矢状切面上的2型表现为楔形结缔组织，在逐渐变细的游离边缘含有胶原蛋白，在附着于关节囊的外周部分含有脂肪。第三型无软骨样结缔组织伸入关节。4型关节间隙周围有不规则、厚的胶原、脂肪和软骨块。儿童半月板以1型为主。在成人中，2型颈椎病主要发生在C1-2，3型颈椎病主要发生在下颈椎小关节。发现的少数4型颈椎病与小关节退变有关。2型和4型脑梗死MRI可显示。在MRI图像上，椎间盘的胶原部分呈低信号，脂肪部分呈高信号。很少有符合传统解剖学描述的脊椎动物。
An analysis of the cervical facet joint menisci was done in which cryomicrotomy sections were correlated with magnetic resonance (MR) images. In parasagittal anatomic sections in ten cadavers, 10-69 years of age at death, four types of meniscus were defined. Type 1 was a thin washer of dense connective tissue covering 50% or more of the joint space. Type 2 in sagittal section appeared as a wedge of connective tissue containing collagen in the tapering free edge and fat in the peripheral portion attached to the joint capsule. Type 3 had no meniscuslike connective tissue extending into the joint. Type 4 had irregular, thick masses of collagen, fat, and cartilage in the periphery of the joint space. Menisci in the child were predominantly type 1. In adults type 2 menisci predominated at C1-2 and type 3 in the lower cervical facet joints. The few type 4 menisci found were in association with facet joint degeneration. Types 2 and 4 menisci could be demonstrated with MR imaging. In MR images the collagenous portion of the menisci were of low signal intensity, and the fat was of higher signal intensity. Few menisci conform to the traditional anatomic description.
