Dural arteriovenous fistula with crista galli erosion in a patient with suspected sinusitis.

Radiol Case Rep 2021 May 25;16(5):1028-1031. Epub 2021 Feb 25.

Department of Neurological Surgery, Juntendo University Urayasu Hospital, 2-1-1 Tomioka, Urayasu, Chiba, 279-0021, Japan.

Dural arteriovenous fistula (dAVF) of the anterior cranial fossa is an aggressive entity with a high risk of intracranial hemorrhage. A 38-year-old woman presented to our institution with nasal obstruction and discharge. Computed tomography (CT) scans performed for suspected sinusitis revealed erosion of the crista galli predominantly on the left side. Read More

The relationship between the distal metatarsal articular angle and intersesamoidal crista: An osteological study.

Foot (Edinb) 2017 Mar 17;30:5-12. Epub 2017 Jan 17.

Evolutionary Studies Institute, University of Witwatersrand, 1 Jan Smuts Avenue, Braamfontein, Johannesburg, 2000, South Africa; School of Geosciences, University of Witwatersrand, 1 Jan Smuts Avenue, Braamfontein, Johannesburg, 2000, South Africa. Electronic address:

Background: As hallux valgus (HV) progresses, the first metatarsal drifts medially and the subsequent lateral drift of the sesamoids results in intersesamoidal crista erosion. This study aimed to provide a novel method of assessing crista erosion and determine if there is a relationship between that erosion and an increase in the distal metatarsal articular angle (DMAA).

Methods: The DMAA and size of the intersesamoidal crista was measured on the first metatarsals of 120 adult modern human individuals. Read More

A tomographic study of the skull base in primary spontaneous cerebrospinal fluid leaks.

Neuroradiology 2012 May 8;54(5):459-66. Epub 2011 Jul 8.

Service of Neurosurgery, Hospital das Clinicas, Belo Horizonte, Brazil.

Introduction: This study aims to evaluate the existence of anatomic abnormalities in the skull base that could contribute to the origin of primary spontaneous cerebrospinal fluid leaks (PSL).

Methods: Twenty PSL patients were compared with 20 healthy individuals. The following features were measured through an analysis of computed tomography scans: the angles of the petrosal bones and skull base in both the sagittal and coronal planes; the anteroposterior and mediolateral diameters of the anterior skull base, sella, and sphenoid sinus; the depth of the olfactory fossa; the pneumatization of the sphenoid sinus; the position of the crista galli; and the state of the dorsum sellae.

Bone histomorphometry in children with newly diagnosed acute lymphoblastic leukemia.

Pediatr Res 2003 Dec 20;54(6):814-8. Epub 2003 Aug 20.

Department of Pediatrics, Beatrix Children's Hospital, University Hospital Groningen, 9700 RB Groningen, The Netherlands.

The objective of this study was to obtain insight into bone formation and resorption in children with newly diagnosed untreated acute lymphoblastic leukemia (ALL). In 23 consecutive children with ALL, a bone biopsy was taken from the crista iliaca posterior under ketamine anesthesia, together with the diagnostic marrow aspiration, before any treatment was given. Histomorphometric assessment was done of bone volume, bone area, trabecular thickness, osteoid volume, osteoid area, osteoid width, number of osteoblasts, erosion area, and number of osteoclasts.

Veterans Affairs Medical Center, Miami, FL, USA.

A cadaveric and radiographic study was undertaken to demonstrate the change in intersesamoidal crista architecture after an osteotomy that corrects the proximal articular set angle (PASA). Three cadaveric first metatarsals with hallux valgus deformity were utilized. Separate Kirschner wires representing the longitudinal axis bisection, PASA, and the long axis of the crista were placed into each specimen. Read More

Pathologic anatomy of hallux abducto valgus.

Division of Basic Sciences, New York College of Podiatric Medicine, New York.

HAV is a joint deformity that has some very characteristic anatomic features but that may be developed from a variety of interactive causes, both anatomic and functional. In the normal condition, the first metatarsal bone and hallucal phalanges form an axial array of bones. At the first metatarsophalangeal joint this arrangement is stabilized by a set of muscles whose tendons surround the joint. Read More
