The new solution for the bilateral severe thumb hypoplasia

Area of Science:

• Hand Surgery
• Pediatric Orthopedics
• Congenital Hand Anomalies

Background:

• Thumb hypoplasia, a form of radial longitudinal dysplasia, presents with varying degrees of thumb underdevelopment.
• Existing treatment strategies for hypoplastic thumbs may not always align with cultural preferences for aesthetic outcomes, particularly in Eastern countries.
• Parents often seek alternative surgical interventions to achieve a more typical hand appearance.

Purpose of the Study:

• To describe a two-stage surgical reconstruction technique for bilateral severe thumb hypoplasia.
• To evaluate the functional and aesthetic results of the described surgical method.
• To address the dual goals of maximizing thumb function and meeting parental aesthetic expectations.

Main Methods:

• A two-stage surgical approach was employed for a pediatric patient with bilateral severe thumb hypoplasia (Blauth Ⅳ left, Blauth ⅢB right).
• The surgical technique focused on reconstructing the thumb to improve both appearance and function.
• Detailed surgical steps were documented for reproducibility.

Main Results:

• The two-stage surgical reconstruction yielded favorable outcomes in terms of thumb appearance.
• Significant improvements in thumb functionality were observed post-surgery.
• The results successfully met the aesthetic expectations of the patient's parents.

Conclusions:

• The described two-stage surgical technique is effective for treating bilateral severe thumb hypoplasia.
• This approach offers a viable option for improving both the function and aesthetic appearance of hypoplastic thumbs.
• The method successfully balances clinical results with patient and family satisfaction.
