Border Digit Transposition and Intramedullary Nail Fixation for Third or Fourth Ray Amputation

Area of Science:

• Hand surgery
• Orthopedic surgery
• Reconstructive surgery

Background:

• Central ray amputation (third or fourth finger) creates a gap between remaining digits.
• This gap can impair hand function, leading to difficulty grasping small objects.
• Current surgical methods (ligament suturing, digit transposition) often require prolonged immobilization, risking complications like gapping or nonunion.

Purpose of the Study:

• To propose and evaluate the use of an intramedullary nail for metacarpal fixation in ray transposition surgery.
• To assess the potential benefits of this technique, including early mobilization and reduced complications.

Main Methods:

• The study proposes employing an intramedullary nail for stabilizing the metacarpal bone after ray transposition.
• This method aims to provide rigid fixation, facilitating early patient mobilization.

Main Results:

• Intramedullary nail fixation allows for early mobilization after ray transposition.
• This approach may reduce the incidence of stiffness and hardware-related irritation.
• Early mobilization can potentially expedite the patient's return to work.

Conclusions:

• Intramedullary nail fixation is a promising technique for managing gaps after central ray amputation.
• It offers advantages over traditional methods by enabling early mobilization.
• This technique may improve functional outcomes and reduce recovery time for patients.
