摘要
目的:马氏韧带(MAL)的骨化会导致马氏韧带孔(MAF)的形成,而马氏韧带孔的形成与衰老有关。MAL 将腰椎背侧韧带的内侧分支拴在腰椎上。腰椎骨化的 MAL 会压迫背侧韧带的内侧分支,从而引起腰痛。以往的研究尚未报道与 MAL 骨化相关的年龄范围。本研究的目的是确定腰椎MAL骨化的发生率及其与衰老的关系,并测量腰椎各级新形成的MAF:本研究对泰国孔敬大学 187 名捐献者的 935 块干腰椎骨进行了检测,其中包括 93 名女性和 94 名男性。研究重点是 MAL 的骨化模式,将其分为三种模式:结果:我们发现,50% 以上的骨化 MAL 发生在 30-45 岁年龄段,且发生频率随年龄增长而增加。腰椎 MAL 骨化的发生率为 72.73%,尤其是女性左侧 L5(76.92%)。MAF的宽度在性别间无显著差异,但左侧(2.46 ± 1.08;n = 76)大于右侧(2.05 ± 0.95;n = 72)(P = 0.016):结论:MAL与MAF的骨化会随着年龄的增长而发展,导致神经受压引起腰痛。医生在麻醉阻滞治疗腰背痛时应注意 MAF。
Anatomy of mamillo-accessory foramen and prevalence of ossified mamillo-accessory ligament in lumbar vertebrae related to age.
Purpose: Ossification of the mamillo-accessory ligament (MAL) results in the formation of a mamillo-accessory foramen (MAF), which is associated with aging. The MAL tethers the medial branches of the lumbar dorsal rami to the lumbar vertebrae. A MAL ossified at the lumbar vertebrae can cause low back pain by compressing the medial branch of a dorsal ramus. Age ranges related to ossification of the MAL have not been reported in previous studies. The objective of the present study was to determine the prevalence of ossification of the MAL in the lumbar column and its relationship to aging, and to measure the newly formed MAF at each level of the lumbar vertebrae.
Methods: This study examined 935 dried lumbar vertebrae from 187 donors at Khon Kaen University, Thailand, consisting of 93 females and 94 males. The research focused on ossification patterns of the MAL, categorizing them into three patterns.
Results: We found that over 50% of ossified MAL occurred in the 30-45-year-old range and the frequency increased with age. The prevalence of ossified lumbar MAL was 72.73%, especially in L5 on the left side in females (76.92%). The width of the MAF did not differ significantly between the sexes, but it was greater on the left side (2.46 ± 1.08; n = 76) than the right (2.05 ± 0.95; n = 72) (p = 0.016).
Conclusion: Ossification of the MAL into the MAF progresses with age, leading to low back pain from nerve compression. Physicians should be aware of the MAF during anesthesia block to treat low back pain.
期刊介绍:
Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit.
Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest.
Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems.
Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
