1
What is Madelung’s Deformity?
A condition characterized by premature fusion of the medial portion of the distal radial physis, resulting in a short bowed radius, ulnar tilt, and dorsal subluxation of the ulna.
New cards
2
What causes Madelung’s Deformity?
Trauma, dysplasia, genetic syndromes, or idiopathic causes.
New cards
3
What is Carpal Coalition?
Fusion of two or more carpal bones, which can be acquired or congenital.
New cards
4
What is the most common type of Carpal Coalition?
The luno-triquetral coalition.
New cards
5
What percentage of Carpal Coalition cases are bilateral?
60%.
New cards
6
What is Distal Radioulnar Synostosis?
An abnormal osseous or fibrous fusion of the distal radius and ulna.
New cards
7
What is Polydactyly?
An increase in the number of fingers or toes.
New cards
8
What is the most common developmental anomaly of the hand?
Syndactyly.
New cards
9
What is Syndactyly?
Fusion of the skin between digits or bony fusion of phalanges of adjacent digits.
New cards
10
When does Syndactyly occur during fetal development?
During the 5th week.
New cards
11
What are the two main types of fusion in Syndactyly?
Fusion of skin (syndactyly) and bony fusion (synostosis) of phalanges.
New cards
12
What are the potential causes of Carpal Coalition?
Acquired causes such as inflammatory arthritis or congenital causes due to failure of embryonic cartilaginous segmentation.
New cards
13
What imaging course are these abnormalities associated with?
RAD6210 - Normal Imaging of the Spine & Extremities.
New cards
14
Who is the instructor for the RAD6210 course?
Dr. F. Jarrett-Thelwell.
New cards
15
What is the result of Madelung's Deformity on the radius and ulna?
It causes a relatively long ulna compared to the radius.
New cards
16
What kind of fusion does Distal Radioulnar Synostosis represent?
Either osseous or fibrous fusion.
New cards
17
What is the resource link provided for further information on Post-Traumatic Distal Radioulnar Synostosis?
https://www.sciencedirect.com.
New cards
18
What are the consequences of Madelung's Deformity on the distal radial articular surface?
Ulnar tilt and volar tilt.
New cards
19
Is Syndactyly more commonly associated with skin fusion or bony fusion?
It is the most common developmental anomaly, associated with both skin and bony fusion.
New cards
20
What is a significant characteristic of the luno-triquetral coalition?
It is the most common coalition among carpal bones.
New cards
21
In Syndactyly, what typically occurs during the 5th week of fetal development?
The fusion of digits.
New cards
22
Identify one acquired cause of Carpal Coalition.
Inflammatory arthritis.
New cards
23
Identify one congenital cause of Carpal Coalition.
Failure of embryonic cartilaginous segmentation.
New cards
24
How does Madelung's Deformity generally affect the ulna?
It may lead to dorsal subluxation or dislocation at the distal radioulnar joint (DRUJ).
New cards
25
In Polydactyly, what is the common effect on fingers or toes?
An increase in their number.
New cards
26
What is the likely outcome for the distal articular surface of the radius in patients with Madelung’s Deformity?
It experiences both ulnar and volar tilt.
New cards
27
What age range is typically observed in clinical presentations of Syndactyly?
It is usually diagnosed at birth or shortly after.
New cards
28
What distinguishing feature does Distal Radioulnar Synostosis demonstrate?
Abnormal fusion of the radius and ulna.
New cards
29
What is a common consequence of abnormal development in carpal bones?
Carpal Coalition.
New cards
30
What is considered a normal variant in wrist and hand congenital anomalies?
Syndactyly and Polydactyly can be considered normal variants in some cases.
New cards
31
How does the presence of Madelung’s Deformity affect forearm movement?
It can limit or alter the range of motion due to the altered alignment of bones.
New cards
32
What is the medical term for a fusion of two or more carpal bones?
Carpal Coalition.
New cards
33
In what context would you'd find Madelung's Deformity mentioned?
In discussions of congenital deformities affecting the wrist and hand.
New cards
34
What type of professional typically addresses conditions like Syndactyly and Polydactyly?
Pediatric orthopedic surgeons or hand specialists.
New cards
35
How does Madelung's Deformity impact the relative length of the ulna?
It is usually longer in comparison to the radius.
New cards
36
What links to further details on Polydactyly were provided?
http://radiopaedia.org/articles/polydactyly.
New cards
37
Is Madelung’s Deformity commonly genetic in nature?
Yes, it can be associated with genetic syndromes.
New cards
38
What is the role of imaging in diagnosing these wrist and hand anomalies?
Imaging assists in visualizing bone structure and abnormalities for proper diagnosis.
New cards
39
What type of imaging course includes congenital anomalies like Syndactyly and Polydactyly?
