摘要

背景小腰肌(PMi)是腹后肌腰肌群中最不稳定的肌肉。这块肌肉呈纺锤形,由一短纺锤形腹部组成,上端延伸为一条长肌腱,插入耻骨栉膜和髂耻弓。本研究旨在获得有关该肌肉的更多详细信息,并扩展有关其形态和形态计量学的知识。当发现 PMi 时,对其起源、插入、长度、宽度和肌骨比的解剖变异进行测量。结果 在 12 个病例中发现了 PMi,其中 10 例为双侧,2 例为单侧。所有病例的起源都是恒定的,除三例外,均延伸至髂筋膜和髂耻骨突。形态计量分析显示,近端肌腹和远端肌腱的平均长度分别为 4.52 ± 1.35 厘米和 13.05 ± 0.90 厘米。肌腹的平均宽度为 1.71 ± 0.17 厘米,肌腱的平均宽度为 0.47 ± 0.10 厘米。平均而言,肌腹占整个肌肉肌腱单位的近端 33.71 ± 6.15%。当肌腱接近插入水平时,形态变化更加明显。肌肉远端与髂筋膜的附着可能部分控制着髂腰肌的位置和机械稳定性,这种间接功能可能与髂腰肌炎症和病理有关。然而,建议开展进一步研究,以确定这块残余肌肉在人体中的生物力学有效性和临床适用性。

Reappraisal of the morphological and morphometric study of the psoas minor muscle with clinical and developmental insights: cadaveric study.
BACKGROUND The Psoas Minor (PMi) is the most unstable muscle of the psoas group of the posterior abdominal muscle. This muscle has a fusiform shape and consists of a short fusiform belly continuing distally as a long tendon inserted on the pecten pubis and the iliopectineal arch. The present study was conducted to obtain more detailed information about the muscle and to expand knowledge about its morphology and morphometry. MATERIALS AND METHODS The posterior abdominal wall of 30 adult cadavers was dissected. Anatomical variabilities in origin, insertion, length, width, and muscle-to-cone ratio were measured when PMi was found. The data collected was interpreted descriptively. RESULTS PMi was found in 12 cases, ten bilateral and two unilateral. The origin was constant in all cases and, except for three cases, extended into the iliac fascia and the iliopubic eminence. Morphometric analysis revealed that the average length of the proximal muscle belly and distal tendons was 4.52 ± 1.35 cm and 13.05 ± 0.90 cm, respectively. The mean width of the muscle belly was 1.71 ± 0.17 cm, and that of the tendon was 0.47 ± 0.10 cm. On average, the muscle belly occupied the proximal 33.71 ± 6.15% of the total musculotendinous unit. CONCLUSIONS Findings confirm the inconsistency of PMi in the study population. Morphological variations became more evident as the tendon approached the insertion level. The muscle's distal attachment to the iliac fascia may partially control the position, mechanical stability of the underlying iliopsoas and this circumstantial function may be clinically related to iliopsoas inflammation and pathology. However, further studies recommended to determine biomechanical validity and clinical applicability of this vestigial muscle in human.

期刊介绍: "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
