Summary
This study introduces a new classification for cleft hand malformations, improving the categorization of diverse presentations. The refined system aids in understanding and managing various types of cleft hand deformities.
Area of Science:
- Orthopedics
- Developmental Biology
- Genetics
Background:
- Cleft hand is a congenital malformation with diverse clinical presentations.
- Existing classifications may not fully capture the spectrum of this anomaly.
Purpose of the Study:
- To propose a novel classification system for cleft hand deformities.
- To enhance the understanding and management of cleft hand variations.
Main Methods:
- Analysis of clinical data and radiographs from 31 patients (54 cleft hands).
- Inclusion of 225 cleft hands from existing literature.
- Classification based on schematic radiographic drawings, extending previous proposals.
Main Results:
- A new classification categorizes cleft hands into five types: Median, Medioradial, Radial, Medioulnar, and Ulnar.
- Identified associations between cleft hand types and unilateral presentation or combined cleft feet.
- Radiographic findings indicate predominance of aplasia in radial cleft hands and synostoses in median cleft hands.
Conclusions:
- The proposed classification provides a comprehensive framework for the diverse spectrum of cleft hand malformations.
- This system incorporates previously less-defined categories like medioulnar and ulnar cleft hands.
- Facilitates improved clinical assessment and potentially treatment strategies for cleft hand.
