What causes the carrying angle of the elbow?
Certain fractures of the elbow can increase the carrying angle of the elbow, causing the arms to stick out too much from the body. This is called an excessive carrying angle. Other fractures of the elbow can decrease the carrying angle of the elbow. If the angle is decreased, the arm points toward the body.
What are the pathologies associated with cubitus valgus and varus?
Women usually have a more pronounced Cubitus valgus than men. The deformity can also occur as a complication of fracture of the lateral condyle of the humerus, which may lead to tardy/delayed ulnar nerve palsy. The opposite condition is cubitus varus (736.02)….

What fracture causes cubitus valgus?
Non-union of lateral condyle humerus fractures can cause progressive cubitus valgus deformity and has been reported to be the most common cause of TUNP13, 14.
What causes the carrying angle?
The carrying angle apparently develops in response to pronation of the forearm and keeps the swinging upper extremity away from the side of the pelvis during walking [14]. Anatomically, the carrying angle in human adults is approximately 10° in men and 13° in women [21].
What causes gunstock deformity?
Cubitus varus or bow elbow or gunstock deformity is the result of malunion occurring as a complication of supracondylar fracture of the humerus. It occurs in only the extension type of supracondylar fracture of the humerus, causing a reduction or loss of the carrying angle.
How can we reduce carrying angles?
The only way to reduce the carrying angle is to undergo a surgery at this age. The most common cause of this deformity is unattended fractures in childhood. Normally if there is no other complaint to the patient it is left as such because elbow joint is a non-weightbearing joint. Xrays of bilateral elbow needed.
What causes cubitus varus?
What muscles make your elbow bend?
Tendons
- biceps tendon, which attaches the biceps on the front of the arm to the radius, enabling you to forcefully bend your bend your elbow.
- triceps tendon, which attaches the triceps to the ulna, enabling you to forcefully straighten your elbow .
What is a valgus deformity?
Valgus knee deformity is defined as a tibio-femoral angle of greater than 10°. Typically, the deformity is the result of changes to both the bony and soft-tissue components around the knee.
Why do I have cubitus valgus?
There are two possible causes for cubitus valgus: a congenital condition or a fracture. The two congenital conditions that commonly cause cubitus valgus are Turner syndrome and Noonan syndrome. Turner syndrome is a chromosomal disorder in which a female is born with only one X chromosome.
Can cubitus valgus be cured?
Cubitus valgus is the most common complication of lateral condylar fractures. Various combinations of osteotomy and fixation have been described to correct valgus deformity. We are using distraction osteogenesis with Ilizarov technique to treat 11 elbows in 11 patients with cubitus valgus.
Which condition causes gun stock deformity?
Malunion of supracondylar fractures often leads to cubitus varus, or “gunstock deformity.” This condition is a triplanar malalignment of the elbow, characterized by varus angulation in the coronal plane, extension in the sagittal plane, and internal rotation in the transverse plane.
Why does avascular necrosis cause scaphoid fracture?
Avascular necrosis: This is a complication in which cells of the scaphoid bone die due to lack of blood supply, causing bone collapse and arthritis. This usually happens in case of displaced fractures, as the displaced bone fails to get proper nutrients.
What muscle straightens your arm?
triceps
The muscle that extends, or straightens, the arm is the triceps, which arises on the humerus and attaches to the ulna at the elbow; the brachialis and biceps muscles act to bend the arm at the elbow.
What’s the inside of elbow called?
Technically, you can refer to the area as the antecubital fossa. Antecubital is an adjective meaning “of or relating to the inner or front surface of the forearm” (in Latin ante means “before” and cubitum means “elbow”). Fossa is a Medieval Latin borrowing that is used for an anatomical pit, groove, or depression.
What is cubitus valgus?
Cubitus valgus is a deformity in which the forearm is angled out away from the body when the arm is fully extended. When it affects both arms, it’s known as cubitus valgus bilateral.
Is valgus deformity genetic?
These studies estimated that family history of hallux valgus was present in 63% to 90% of patients.
What are the causes of Cubitus valgus?
There are two possible causes for cubitus valgus: a congenital condition or a fracture. The two congenital conditions that commonly cause cubitus valgus are Turner syndrome and Noonan syndrome. Turner syndrome is a chromosomal disorder in which a female is born with only one X chromosome.
How do I know if I have cubitus valgus?
When your palm is facing upward and your arm is extended, you may have cubitus valgus if your carrying angle, or the degree to which your arm is angling away from your body, exceeds 15 degrees. However, it’s possible to be diagnosed with cubitus valgus with a carrying angle anywhere between 3 and 29 degrees.
Can cubitus valgus lead to ulnar neuropathy?
Cubitus valgus can also lead to a condition called tardy ulnar nerve palsy, a type of ulnar neuropathy. This is a chronic condition that is commonly associated with cubitus valgus.
What is the carrying angle of Cubitus valgus?
However, it’s possible to be diagnosed with cubitus valgus with a carrying angle anywhere between 3 and 29 degrees. The angle is often more pronounced in women.
