Long-term function after pseudo-pollicization of the little finger

Area of Science:

• Hand surgery
• Pediatric orthopedics
• Congenital hand differences

Background:

• Congenital absence or severe hypoplasia of the thumb presents unique challenges in hand function.
• Traditional pollicization may not be suitable for all cases, particularly when scissor-action pinch is already established.
• Alternative surgical techniques are needed to improve prehensile function in affected children.

Purpose of the Study:

• To present a novel surgical technique for improving pinch function in children with thumb hypoplasia.
• To facilitate pinch between the ring and little fingers when index finger pollicization is contraindicated.
• To offer a less conspicuous surgical option compared to traditional pollicization.

Main Methods:

• A surgical technique was developed to enhance the web space between the ring and little fingers.
• The procedure aims to facilitate tip-to-tip pinch using these digits.
• The technique was applied to five pediatric patients with thumb hypoplasia.

Main Results:

• The surgical technique successfully facilitated opening of the web space between the ring and little fingers.
• Improved pinch function between the ring and little finger tips was observed post-surgery.
• The functional benefits of the procedure were sustained during follow-up periods.

Conclusions:

• This surgical technique provides a viable option for improving pinch function in select cases of thumb hypoplasia.
• The method offers functional advantages by enhancing interdigital pinch, particularly when other surgical interventions are not advised.
• The procedure demonstrates sustained functional value for children as they mature.
