In isolation, this aspect of the deformity is called cavus deformity. Second, the forefoot is curved inward or medially (toward the big toe). In isolation, this aspect of the deformity is called metatarsus adductus. Third, the heel is turned inward. This is a natural motion of the heel and subtalar joint, typically referred to as inversion. In clubfoot deformity, the turning in (inversion) of the heel is fixed (not passively correctable) and considered a varus deformity. Fourth, and finally, the ankle is pointed downward.

6 Clubfoot can also be present in people with genetic conditions such as loeys-dietz syndrome. Genetic mapping and the development of models of the disease have improved understanding of developmental processes. Its inheritance pattern is explained as a heterogenous disorder using a polygenic threshold model. The pitx1-tbx4 transcriptional pathway has become key to the study. Pitx1 and tbx4 are uniquely expressed in the hind limb. 7 diagnosis edit diagnosis of clubfoot deformity is by physical examination. Typically, a newborn is examined shortly after delivery with a head to toe assessment. Examination of the lower extremity and foot reveals the deformity, which may affect one or both feet. Examination of the foot shows four components of deformity. First, there is a higher bubble arch on the inside of the foot. This component of the deformity can occur without the other aspects of clubfoot deformity.
Research has not yet pinpointed the root cause, but many findings agree that "it is likely there is more than one different cause and at least in some cases the phenotype may occur as a result of a threshold effect of different factors acting together.". Early amniocentesis (1113 wks) is believed to increase the rate of clubfoot because there is an increase in potential amniotic leakage from the procedure. Citation needed Underdevelopment of the bones and muscles of the embryonic foot may be another underlying cause. In the early 1900s it was thought that constriction of the foot by the uterus contributed to the occurrence of clubfoot. Citation needed Underdevelopment of the bones also affects the muscles and tissues of the foot. Abnormality in the connective tissue causes "the presence of increased fibrous tissue in muscles, fascia, ligaments and tendon sheaths". 5 Genetics edit mutations in genes involved in muscle development are risk factors for clubfoot, specifically those encoding the muscle contractile complex (MYH3, tpm2, tnnt3, tnni2, and myh8). These can cause congenital contractures, including clubfoot, in distal arthrogryposis (DA) syndromes.
