Combined conduit score of sinovenous stenosis
The combined conduit score (CCS) is a grading scheme for the assessment of the degree of transverse-sigmoid sinus stenosis in the setting of idiopathic intracranial hypertension. The score was initially developed for ATECO MR venography 1.
Parameters
Assessment is performed using maximum inten...

Shunt-dependency in symptomatic aneurysmal subarachnoid hemorrhage score
The shunt-dependency in symptomatic aneurysmal subarachnoid hemorrhage (SDASH) score is a harmonized score for the prediction of hydrocephalus requiring shunting after subarachnoid hemorrhage. The tool is employed in the acute phase to predict which patients will require shunting, rather than to...

Osteochondritis dissecans (surgical staging)
Osteochondritis dissecans can be classified at surgery into 4 stages:
stage I
stable
lesion in continuity with the host bone
covered by intact cartilage
stage II
stable on probing
partial discontinuity of the lesion from the host bone
stage III
unstable on probing
fragment not dislocat...

Ciliopathies
Ciliopathies refer to diseases due to malfunctioning cilia (singular: cilium). Cilia are organelles that are external extensions of the cell membrane. Cilia fall into two main types: primary (or immotile) cilia and motile cilia.
Clinical presentation
Primary cilia are found in virtually every...

Johansson classification
The Johansson classification of periprosthetic hip fractures was the first classification system proposed and is the simplest. It is based on the level of the fracture in relation to the prosthesis.
type I: fracture proximal to the tip of the prosthesis with the stem still in contact with the m...
Article
Cooke and Newman classification
The Cooke and Newman classification of periprosthetic hip fractures is a modification of the Bethea classification proposed several years earlier.
type I
explosion type fracture, comminuted around the stem of the implant
the prosthesis is always loose and the fracture is inherently unstable

American Academy of Orthopedic Surgeons classification of periprosthetic hip fractures
The American Academy of Orthopedic Surgeons classification of periprosthetic hip fractures divides the femur into three separate regions:
level I: proximal femur distally to the lower extent of the lesser trochanter
level II: 10 cm of femur distal to level I
level III: femur distal to level...

Risk of malignancy index in ovarian tumors
The risk of malignancy index (RMI) in ovarian tumors is a validated clinical tool used for risk stratification of ovarian lesions, to guide further management 1-3.
Classification
The score incorporates the patient's menopausal status (M), ultrasound features of the lesion (U), and the serum CA...

Nottingham classification
The Nottingham classification is used at the end of work up of a breast lesion to help guide management.
A = malignant
lesion needs surgical excision regardless of biopsy result
B = indeterminate
will accept a benign biopsy result, but only if it is congruent with imaging, i.e. a well circum...

Tabar 5-tier grading system
The Tabar 5-tier grading system is used to classify mammographic lesions. This should not be confused with the Tabar classification of parenchymal patterns in breast imaging. It is a separate but translatable system to the BI-RADS classification system (please note that Tabar grade 3 ≠ BI-RADS 3...
