Dynamic load response of human dura mater at different velocities

Journal of the Mechanical Behavior of Biomedical Materials, 2023
Despite of its assumed role to mitigate brain tissue response under dynamic loading conditions, the human dura mater is frequently neglected in computational and physical human head models. A reason for this is the lack of load-deformation data when the dura mater is loaded dynamically.

Anatomic and Biomechanical Properties of Human Lumbar Dura Mater

Anesthesia & Analgesia, 1993
Determinants of dural defects subsequent to deliberate or accidental dural puncture include the equipment, techniques, and the inherent anatomic and biomechanical properties of dura mater. These properties were studied in specimens of human and canine lumbar dura mater in an attempt to delineate the structure of the tissue and to characterize its ...

Local Mechanical Anisotropy in Human Cranial Dura Mater Allografts

Journal of Biomechanical Engineering, 1998
Human cranial dura mater (CDM) allograft’s success as a repair biomaterial is partly due to its high mechanical strength, which facilitates its ability to form water-tight barriers and resist high in-vivo mechanical loads. Previous studies on CDM allograft mechanical behavior used large test specimens and concluded that the allograft was mechanically ...

Reconstruction of orbital fractures with dehydrated human dura mater

Journal of Oral and Maxillofacial Surgery, 2000
The best method for reconstructing the fractured orbital floor remains controversial. This article evaluates the usefulness of dehydrated human dura mater for orbital floor reconstruction after facial trauma.A retrospective analysis of 55 patients who had undergone surgical repair of orbital fractures was performed.

EXPERIENCE WITH LYOPHILIZED HUMAN DURA MATER FOR URETHRAL STRICTURES

The Journal of Urology, 1998
We report our results using lyophilized human dura mater for urethral strictures.The results of 131 urethroplasties using lyophilized human dura mater grafts were reviewed. The etiology of the stricture was unknown in most cases and 44.3% had not been previously treated. Mean stricture length was 10 cm.

Revision Myringoplasty with Solvent‐Dehydrated Human Dura Mater (Tutoplast)

Otolaryngology–Head and Neck Surgery, 2001
OBJECTIVESSeveral grafting materials have been used in the reconstruction of the perforations of the tympanic membrane. The use of dehydrated dura homografts as a substitute for the tympanic membrane has not been fully documented. On the other hand, revision surgery is more critical in terms of patients' expectations.

The Resistance of the Human Dura Mater to Needle Penetration

Regional Anesthesia: The Journal of Neural Blockade in Obstetrics, Surgery, & Pain Control, 1992
Methods. An aneroid manometer attached to a needle during lumbar puncture for spinal anesthesia was used to record the pressure in the epidural space, and an attempt was made to define the moment the needle contacted and indented the dura mater. Results.

Catecholaminergic Innervation of the Human Dura Mater Involved in Headache

Headache: The Journal of Head and Face Pain, 1998
The catecholaminergic innervation of cranial dura mater in humans was studied by examining several dural zones (vascular, perivascular, intervascular) in different regions (basal, calvarial, occipital, frontal, tentorial, parietal, temporal). The results demonstrate that catecholaminergic nerve fibers are present in human cranial dura

[Urethroplasty with lyophilized human dura mater].

Archivos espanoles de urologia, 1995
This article reports our experience with lyophilized human dura in the treatment of complex urethral stenosis.Seven patients with iatrogenic/inflammatory urethral stricture underwent a 13 cms long x 1.5 cms wide medial urethral augmentation.During a mean follow-up of 23 months, good results accounted for 85.7%.Lyophilized dura patches constitute a ...

Physical and chemical processing for a human dura mater substitute

Biomaterials, 2002
Allogenic human fascia lata used in neurosurgery, as dura mater substitute, can be associated with a risk of viral and bacterial transmission. Chemical and physical procedures, developed to inactivate virus and bacteria, have been applied to fascia lata. The aim of this study consists in the evaluation of the biological properties of this treated graft.
