“…Zimny et al [1986] claimed that the meaning of the greatest density of innervation in the area of maximum movement of a ligament is to provide propriocective information and protection against excessive stretching, overstrain or compression. Yahia et al [1988Yahia et al [ , 1989 confirmed the presence in these ligaments of Ruffini and Pacini corpuscles, most probably involved both in sensing mechanical loads applied to ligaments during motion and in local control of blood flow. Due to fibres interconnecting with adjacent fascia and tendons, it also may be postulated, in accordance with Prestar [1982], Aspden [1987] and Putz [1992], that the lumbar interspinous ligaments do not only limit flexion and separate the interspinal and sacrospinalis muscles of the two sides, but that they are also capable of perceiving any tensional difference between paravertebral and abdominal muscles.…”

In textbooks of human anatomy and atlases of spinal surgery, the lumbar interspinous ligaments are described and illustrated in various and often conflicting ways. Thirty-four lumbar vertebral columns (19 males, 15 females, range 17–92 years old), sampled at autopsy, were studied by dissection and macroscopic analysis. The orientation of the fibre bundles was evaluated in the sagittal plane by tracing a reference line parallel to the cranial border of the spinous process, and the degree of bundle tilting with reference to this line was measured in the ventral, middle and dorsal parts of the ligament. Histological and immunohistochemical (anti-S100) studies of the ligaments, on sagittal, frontal, and transversal planes, were also carried out. In vivo radiological validation was performed in 25 patients by MR and CT imaging. Macroscopically, the interspinous ligaments are consistently composed of bundles of fibres arranged in a characteristic pattern. Together, they present an oblique orientation from anterior to posterior in a caudal-cranial direction. In their ventral part the bundles form a slight curve with a posterior-inferior concavity. In the middle part, the bundles are thicker and arranged in an italic S shape with a mean degree of tilting of 52 ± 14, 21 ± 12 and 50 ± 17 in the anterior, intermediate and posterior subzones of the L2–L3 ligaments and of 32 ± 14, 11 ± 9 and 18 ± 11 in the anterior, intermediate and posterior subzones of the L4–L5 level. The dorsal part consists of obliquely ascending bundles of fibres mostly converging in the supraspinous ligament. Histologically, these ligaments are mainly composed of collagen fibres, whereas the elastic fibres are ubiquitous, although mostly concentrated in the ventral part, which is closely linked to the yellow ligament. The interspinous ligament is well supplied by small blood vessels and sensory nerves, the latter particularly in its dorsal part and on its lateral surfaces. According to collected data, the structure of the interspinous ligaments reflects their function, i.e., the italic S-shaped course of the fibrous bundles represents an available reserve of length in a poorly elastic ligament.

“…Additional publications have been devoted to blood supply [Scapinelli, 1958b] and sensory innervation [Yahia et al, 1988;Jiang et al, 1995]. Fujiwara and Tamai [2000] used MR imaging to assess normal or pathologic changes in the interspinous ligaments in living subjects, but without any reference to fibre bundle orientation.…”

“…A number of hypotheses have been put forth to explain this phenomenon including physical changes related to musculoskeletal overuse/disuse, chronic improper posture, and imbalance of paraspinal musculature and its innervation. 38,39 At a molecular level, the development of scoliosis has been loosely associated with abnormal collagen distribution, 40,41 reduced serum melatonin levels, 42 altered growth factor expression (TGFβ and b-FGF), 43 and genetic polymorphisms involving IL-6 and MMP-3 44 as well as estrogen receptors. 45 The relationship of scoliosis and paraesophageal hernia leads to the hypothesis that these entities might arise from similar pathogenetic abnormalities.…”

“…Mechanoreceptors are pressure-sensitive corpuscles that have been identified in the ligaments of almost all the joints of both humans and animals [3,9,10,11,16,17,24,25,26]. These receptors have been shown to send impulses to the brain when the knee joint is flexed and extended as well as internally and externally rotated [11].…”

Ten canine anterior cruciate ligaments (ACLs) were harvested while preserving their bony attachments. Specimens were stained using a modified gold chloride technique, divided into thirds, and serially sliced at 0.5 microns. The slides were viewed to count the mechanoreceptors present. The average numbers of receptors found were: proximal 67, middle 43, and distal 18 (AN-OVA: P<0.001). The statistical test (Sheffé) revealed that the proximal third contained a greater mean number of receptors (S=3.8). No significant difference was found between the number of receptors in the middle and distal thirds (S=0.85).Résumé Les ligament croisés antérieurs de dix chiens ont été prélevés avec leurs insertions osseuses. Un fixateur externe a été utilisé pour garder le ligament à sa longueur de repos. Les ligaments ont été colorés au chlorure d'or puis divisés en tiers proximal, moyen et distal. Chaque section a ensuite été coupée de façon sériée à intervalle de 5 microns et montée sur lame pour étude au microscope. Le nombre moyen de récepteurs par tiers du ligament étais: proximal 67, moyen 43 et distal 18. Les ré-sultats de l'analyse de variance ont démontrés une diffé-rence entre les moyennes de récepteurs de chaque tiers (P<0.001). Le test statistique de Sheffé a montré que le tiers proximal contenait un plus grand nombre de récep-teurs (S=3.8) alors qu'il n'y avait pas de différence significative entre les tiers moyens et distaux du ligament.
