Anomalous hands with cleft formation between the fourth and fifth digits

Area of Science:

• Hand Surgery
• Congenital Hand Deformities
• Medical Imaging

Background:

• Cleft hand and ulnar ray deficiency are common congenital hand deformities.
• Existing classification systems aim to standardize the diagnosis and treatment of these conditions.

Observation:

• Three pediatric patients presented with similar hand deformities.
• The deformities involved the fourth and fifth digits with associated hypoplasia of the small finger.

Findings:

• Detailed analysis of clinical photographs, radiographs, angiograms, and dermatoglyphic prints was performed.
• The observed deformities did not clearly fit into established ulnar ray deficiency or cleft hand categories.
• Classification challenges were noted based on the International Federation of Societies for Surgery of the Hand system.

Implications:

• The findings suggest limitations in current classification systems for complex hand anomalies.
• Further research may be needed to refine or expand existing classification frameworks.
• Improved classification could lead to more accurate diagnosis and tailored treatment strategies for patients with these rare deformities.
