Q79: Congenital malformations of the musculoskeletal system, not elsewhere classified

Congenital malformations of the musculoskeletal system encompass a group of conditions that are caused by abnormal development of muscles, bones, and connective tissues during pregnancy. These irregularities can be due to various factors such as genetic mutations, environmental influences, or problems with blood supply during foetal development. Often, these conditions are present at birth. Symptoms can vary widely, from non-visible internal malformations that may be asymptomatic to external malformations that may cause significant physical deformity, movement issues, or pain. These conditions can affect different parts of the musculoskeletal system, such as the spine, chest, limbs, muscles, or connective tissue. The progression of these conditions can also differ, from slow development that only becomes apparent in adulthood, to rapid progression that can lead to life-threatening complications if left untreated. While these conditions cannot be transmitted from person to person, some may have a genetic component and may potentially be passed down through families.
