Preliminary soft tissue distraction using external fixator in radial club hand

Area of Science:

• Orthopedics
• Pediatric Surgery
• Hand Surgery

Background:

• Radial club hand involves forearm and wrist malformations.
• Bayne's types III and IV present specific challenges.
• Tendon transfer and centralization are common surgical approaches.

Purpose of the Study:

• To evaluate the efficacy of preliminary soft tissue distraction using external fixators.
• To assess outcomes in patients with Bayne's type III and IV radial club hand deformities.
• To determine the optimal timing for intervention.

Main Methods:

• Soft tissue distraction with an external fixator was performed before centralization and tendon transfer.
• Treatment involved 18 hands from 14 patients with radial club hands.
• Intervention began at a mean age of 8 months, with most surgeries completed before 10 months.

Main Results:

• Adequate soft tissue stretching was achieved in the majority of cases.
• Follow-up averaged 31 months.
• Results were categorized as seven good, eight satisfactory, and one unsatisfactory.

Conclusions:

• Preliminary soft tissue distraction with external fixators is a viable method.
• This technique facilitates subsequent centralization and tendon transfer for radial club hand.
• Early intervention appears crucial for optimal outcomes.
