| Question | Answer |
|---|---|
| What are some symptoms associated with stylohyoid ligament calcification? Give me the AKA's? | compression of external carotid artery by the styloid process can produce pain in orbital or temporal region, can cause nagging pain in pharynx, radiating to mastoid region. AKA's:Styloid process syndrome; Carotid artery syndrome, **Eagle Syndrome |
| Problem swallowing + styloid ligament calification = _______? | Eagle Syndrome |
| What is it called when there is failure of 2 or more segments to seperate during development? they are fused | Congenital Block Vertebra (Wasp waist) There is a C shape in anterior vertebral bodies |
| ________ joint fusion accompanies 50% of the blocked vertebra in Congenital Block Vertebra? | Apophyseal joint fusion, also SP fusion occurs as well |
| Does posterior element fusion accompany surgery fusion or congenital block vertebra? | Congenital Block vertebra |
| What regions are congenital block vertebra most commonly found? | C5/6, T12/L1, L4/L5. in a decreasing order of incidence |
| What is it called when there are 2 or more blocked vertebrae in the cervical and upper thoracic spine? | Klippel-Feil Syndrome (aka: Brevicollis). ratio of male to female is 1:1 |
| ****A classical clinical triad is found in 52% o fthe patients with Klippel-Feil Syndrome, what are they? | 1.Low Posterior hairline 2.Short Webbed neck 3.Decreased cervical range of motion. (think big Matt in our class) |
| What are some of the human systems commonly involved with Klippel-Feil Syndrome? 3 of them | 1.Genital urinary system 2.cardiopulmonary system 3.nervous system |
| Give 8 other conditions that can co-exist with Klippel-Feil Syndrome? | 1.Scoliosis (most common associated condition) 2.rib anomalies 3.Sprengel's deformity (20-25%) 4.Omovertebral bone 5.Atlanto-occipital dysplasia & platybasia 6.Deafness 7.Synkinesia 8.Congenital heart defects |
| Findings similar to Klippel-Feil Syndrome have been found in _____ ____ ____? | fetal alcohol syndrome |
| What is it when the scapula is abnormally high or elevated? is it more common in m/f? | Sprengel's Deformity, more common in females 2:1, and is usually unilateral. |
| 2/3's of patients presenting with Sprengel's deformity have associated features. Give 5? | 1.Scoliosis 2.Hemivertebrae 3.Blocked Vertebrae 4.SBO 5.Cervical Ribs |
| Facts: Sprengel's deformity may be associated with Klippel-Feil (20-25%). Omovertebral Bone = 30-40%. Osseous, cartilaginous or fibrous attachment of the sup scap angle to the post elements of C5 or C6 | (blank) |
| What means anterior displacement relative to the adjacent inferior vertebra? | Cervical Sponylolisthesis |
| What is a rare anomaly, characterized by: absent pedicles bilaterally, dysplasia of the articular processes, SBO, most common in males at C6 level? | Cervical Spondylolisthesis |
| T/F SBO at C6 is rare as an isolated anomaly? | true, usually cervical spondylolisthesis accompanies it |
| Concerning Cervical rib: where is it most common? what percentage of population? is it usually uni/bilateral? more common in m/f? | most common at C7, but can be seen at C6 or C5. 0.5% of population, Bilateral 66% of time, twice as common in femaliens! |
| ***What is a dangerous syndrome that can accompany Cervical ribs? | TOS - Thoracic Outlet Syndrome, where the subclavian vessels or brachial plexus could be compressed |
| When is a TVP of C7 considered elongated? | When the TVP of C7 extends beyond the length of the TVP of T1 |
| What is it called when there is an isolated ossification within the anterior annular fibers of a cervical IVD? | Intercalary bone (ossicle) |
| What is it when there is an isolated ossification within the nuchal ligament? | Nuchal bone (ossicle) |
| Are there usually symptoms associated with the Nuchal Bone? | No its usually asymptomatic |
| What is it called when there is calcification of the nuchal ligament and it attaches to the occiput? | Enlarged EOP, Occipital Spur (this is known to fracture with direct trauma) |
| What is called when there is calcification of the ligament/membrane extending from the posterior aspect of the petrous portion of the temporal bone to the posterior aspect of the posterior clinoid of the sella turcica? | Petroclinoid Ligament Calcification |
| What is it when there is calcification of the ligament/membrane extending from the anterior to the posterior clinoid processes? | Interclinoid Ligament Calcification |
