– See: Pillar View – Discussion:     – demonstrates primarily neural foramina, pedicles, articular masses, apophyseal joints, & relative relationship at lamina;     – oblique views show the pedicle in profile, and also allows assesment of the intervertebral foramina (and osteophytes encroaching            along their margins);         – Technique:     – routine oblique … Read more

Obliquus Capitis Inferior

– origin: the apex of the spine process of the axis; – insertion: the inferior and dorsal part of the transverse process of the atlas; – action: rotates the atlas, turning the face toward the same side; – nerve supply: a branch of the dorsal primary division of the suboccipital nerve; – synergists: Longissimus Capitis, Rectus Capitis Posterior … Read more

Obliquus capitis superior

– origin: the superior surface of the transverse process of the atlas; – insertion: the occipital bone, between the superior and inferior nuchal lines, lateral of the    Semispinalis capitis ; – action: extension and lateral flexion of the head at the neck; – nerve supply: branch of the dorsal primary division of the suboccipital nerve; … Read more

– Avulsion Fracture – Comminuted Fractures – Distal Olecranon Fracture: – Fracture Dislocations – Oblique Fractures – Surgical Approach: – Transverse Fractures – Discussion:     – results from indirect forces (hyperextension)     – frx begins at midpoint of trochlear notch and extends distally to enter semilunar notch;     – amount of frx … Read more

Oblique Metacarpal Shaft Fractures

– Frx Malrotation:     – tend to shorten & rotate rather than angulate;     – may telescope because of proximal pull of extrinsic muscles;     – effect of malrotation:          – if 5 deg of malrotation is accepted, then displacement will  override 10 mm; – Frx Shortening:     … Read more

Nutrient Artery

– See:       – Epiphyseal Artery       – Metaphyseal Artery       – Periosteal Artery – Discussion:      – nutrient artery enters into the diaphysis of long bones through an oblique canal;      – direction of canal is determined by relative amount of growth that has occurred at … Read more
