Second Toe-to-thumb Transfer Using Intramedullary Screw Fixation after Traumatic Thumb Amputation.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Reconstructive Microsurgery

Background:

• Thumb amputation results in substantial hand function loss (40%).
• Toe-to-thumb transfer is a reconstructive option for thumb loss.
• Traditional wire fixation causes stiffness and prolonged rehabilitation.

Purpose of the Study:

• To present a novel technique for toe-to-thumb transfer using intramedullary screw fixation.
• To evaluate the functional and rehabilitation outcomes of this technique.

Main Methods:

• Case report of a patient with traumatic thumb amputation.
• Second toe-to-thumb transfer utilizing intramedullary screw fixation for rigid interosseous fixation.
• Postoperative immediate mobilization protocol.

Main Results:

• The patient achieved immediate thumb mobilization post-surgery.
• This facilitated an earlier return to work.
• Intramedullary screw fixation provided stable reconstruction.

Conclusions:

• Intramedullary screw fixation is a viable and novel method for toe-to-thumb transfers.
• This technique may reduce stiffness and shorten rehabilitation periods.
• The method shows promise for both second and great toe transfers.
