All are true regarding CTEV except:
**Question:** All are true regarding CTEV except:
A. CTEV is a developmental disorder of the foot
B. CTEV is caused by genetic factors
C. CTEV is a result of lack of oxygen during birth
D. CTEV is a disease affecting only infants
**Core Concept:**
CTEV, or clubfoot, is a congenital disorder affecting the foot's development, particularly the tarsal bones and the muscles surrounding them. The condition typically involves excessive flexion and adduction of the foot, leading to abnormal foot positioning and alignment. CTEV is a group of disorders characterized by abnormal foot positioning and is primarily caused by genetic factors, such as mutations in genes related to the development of the foot and limb.
**Why the Correct Answer is Right:**
The correct answer (C) is right because CTEV is primarily caused by genetic factors and not due to lack of oxygen during birth (option D). Although hypoxia can contribute to some cases, the majority of CTEV cases are attributed to genetic factors affecting the development of the foot and limb.
**Why Each Wrong Option is Incorrect:**
A. While CTEV does involve developmental issues, the condition is primarily genetic and not solely developmental (option A).
B. The correct answer discusses the genetic factors contributing to CTEV, but option B is incorrect because CTEV can also result from environmental factors, such as maternal infections or toxins, but these are less common than genetic causes.
D. Option D is incorrect because CTEV can be caused by genetic factors, as mentioned earlier, but it is not exclusively a disease affecting only infants. CTEV can occur in newborns, infants, and even children and adults, although it is more common in infants.
**Clinical Pearl:**
CTEV is an important consideration for healthcare professionals, particularly pediatricians and pediatric orthopedic surgeons, as it can be diagnosed during prenatal ultrasound or immediately after birth. Early intervention with casting or surgery can improve the foot's position and alignment, leading to better outcomes for the patient.
