Toe joint transfers to the finger offer a viable alternative to joint fusion, particularly for traumatic injuries. While complications are common, this vascularized joint transfer technique shows promise for improving finger joint function.

Area of Science:

Orthopedic Surgery
Microsurgery
Reconstructive Surgery

Background:

Metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint reconstruction presents challenges.
Arthrodesis (joint fusion) is a common but function-limiting solution.
Vascularized toe joint transfer offers a potential alternative for joint reconstruction.

Purpose of the Study:

To evaluate the outcomes of vascularized toe joint transfers to the finger.
To compare results in traumatic versus congenital cases.
To assess the functional range of motion and complication rates.

Main Methods:

Retrospective review of 31 toe joint transfers in 26 patients.
Transfers were performed on MCP or PIP joints of the finger.

Follow-up averaged 22.6 months.

Main Results:

Average range of motion (ROM) achieved was 27.2 degrees (17.1-44.3 degrees).
Traumatic group: 30.0 degrees ROM (17.6-47.6 degrees).
Congenital group: 12.8 degrees ROM (14.4-27.2 degrees).
Significant complication rate of 50% observed across all patients.

Conclusions:

Vascularized toe joint transfer is a complex procedure but offers a reasonable alternative to arthrodesis.
The technique shows potential for improved finger joint function, especially in traumatic reconstructions.
Further refinement may enhance the reliability of this reconstructive option.
