The aim of this study was to determine the incidence of nuchal cord at delivery and perinatal outcome. We conducted a retrospective descriptive study from 1992–2008 at the Yaounde General Hospital. Obstetrical and neonatal variables were compared in the loose and tight nuchal cord groups and a control group (no nuchal cord). Of 9275 deliveries recorded, 16.2% had a nuchal cord. Of these nuchal ...

Fetal nuchal cystic hygromas (NCH) are congenital malformations of the lymphatic system and can be defined as an area of sonolucency in the soft tissue of the occipital region, consisting of two symmetrical cavities completely separated by a midline septum (nuchal ligament), with or without internal trabeculae (multiloculated cysts). Diagnosis can be made at first trimester of pregnancy using v...

A highly unusual collagen was secreted by fibroblasts cultured from 150- and 270-d-old fetal calf nuchal ligaments. Purification revealed that this protein (which may be synthesized in a higher molecular weight form) was precipitated at unusually high concentrations of ammonium sulfate and was also eluted from DEAE-cellulose at greater salt concentrations than were types I and III procollagens....

We report on the direct measurement of the molecular diffusion coefficients of water confined to purified bovine nuchal ligament elastin by high resolution q-space NMR imaging. The experimental data indicate that water trapped within an elastin fiber has two distinguishable molecular diffusion coefficients. The component with the slowest mobility has a diffusion coefficient on the order of 10(-...

Nuchal-type fibroma is a recently described, rare, tumor-like process of fibrous tissue occurring chiefly in the dorsocervical area. Nuchal-type fibromas in extranuchal locations are morphologically indistinguishable from lesions involving the nuchal region. Histopathologic findings of nuchal-type fibroma are poorly demarcated, dense collagen bundles with sparsely scattered fibroblasts, some in...

OBJECTIVE There are also few studies demonstrating the relationship between ossification of nuchal ligament (ONL) and ossification of posterior longitudinal ligament (OPLL). We compared the prevalence, location, and type of OPLL between patients with ONL and matched patients without ONL.We also compared the bone mineral densities (BMDs) between the 2 groups. METHODS total of 124 cervical ONL ...

The trapezius muscle originates on the occipital bone, nuchal ligament, spinous process of the 7th cervical vertebra (C7) and all of the thoracic vertebrae (Figure 1). It has three parts. The superior portion (descending fibers) terminates on the posterior margin and superior side of the lateral third of the clavicle. The transverse portion (middle fibers) terminates on the medial margin of the...
