Clinical differences between typical and atypical cleft hand

Summary
Hand pattern profiles distinguish typical cleft hand from atypical forms. Typical cleft hands show longer bones near the cleft, while atypical hands exhibit dysplastic bone formation, aiding in diagnosis.
Area of Science:
- Orthopedics
- Developmental Biology
- Genetics
Background:
- Cleft hand is a congenital limb malformation with diverse clinical presentations.
- Differentiating typical cleft hand from atypical forms is crucial for accurate diagnosis and treatment planning.
- Hand pattern analysis offers a method to characterize skeletal morphology in limb anomalies.
Purpose of the Study:
- To elucidate the distinct clinical features of typical and atypical cleft hand.
- To establish hand pattern profiles for differentiating these conditions.
- To compare metacarpal patterns in typical cleft hand versus failure of formation.
Main Methods:
- Utilized hand pattern profiles to analyze skeletal morphology.
- Compared metacarpal and proximal phalanx lengths relative to unaffected sides.
- Examined bone formation characteristics in atypical cleft hand cases.
Main Results:
- Typical cleft hand cases demonstrated elongated metacarpals or proximal phalanges adjacent to the cleft.
- Atypical cleft hand cases exhibited dysplastic bone formation.
- Distinct metacarpal patterns were observed between typical cleft hand and failure of formation, with typical patterns resembling finger webbing and failure of formation patterns resembling symbrachydactyly.
Conclusions:
- Hand pattern profiles effectively differentiate typical from atypical cleft hand.
- Metacarpal pattern analysis provides valuable insights into the underlying etiology of cleft hand malformations.
- This approach aids in classifying cleft hand subtypes, including failure of formation.
