Congenital syndactyly: a reappraisal
Summary
Digital syndactyly, a common congenital anomaly, is now understood to have two distinct forms: primary and secondary. Management strategies vary based on the complexity of the malformation.
Area of Science:
- Developmental Biology
- Congenital Anomalies
- Surgical Reconstruction
Background:
- Digital syndactyly is a frequent congenital anomaly.
- Previously viewed as a single entity, new research suggests two distinct types.
Purpose of the Study:
- To differentiate between primary and secondary syndactyly.
- To outline management strategies based on syndactyly type and complexity.
Main Methods:
- Review of experimental embryology and morphogenesis studies.
- Clinical observation and surgical case analysis.
Main Results:
- Identified primary syndactyly (developmental error) and secondary syndactyly (re-adhesion).
- Primary syndactyly can be sporadic, a mutation, or part of a syndrome.
- Secondary syndactyly results from mechanical adhesion during healing.
Conclusions:
- Syndactyly management depends on malformation complexity.
- Simple cases require specific surgical techniques (zigzag incision, flaps, grafts) before age two.
- Complex cases necessitate multiple procedures and vigilant correction of growth-related sequelae.

01:29Nondisjunction
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
01:21Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
01:07Development of the Limb Synovial Joints
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
