Improving the extensor lag and range of motion following free vascularized joint transfer to the proximal interphalangeal joint: Part 2. A clinical series.

Background: Free vascularized joint transfer for reconstructing the posttraumatic proximal interphalangeal joint has enjoyed limited popularity because of the low range of motion typically achieved after transfer. One of the commonest complaints is the significant extensor lag. Part 2 of this two-part study is focused on the clinical outcomes following a more anatomical approach to extensor tendon reconstruction.

Improving the extensor lag and range of motion following free vascularized joint transfer to the proximal interphalangeal joint: Part 1. An observational and cadaveric study.

Background: Extension lag is a common occurrence following free vascularized joint transfer reconstruction of the proximal interphalangeal joint, thus limiting the range of motion that is achievable. In this Part 1 study, the anatomical and biomechanical arrangements of the toe proximal interphalangeal joint extensor mechanism were investigated.

Methods: Twelve second toes from 12 fresh cadavers were dissected for examination of the extensor mechanism.

Efficient design of split anterolateral thigh flap in extremity reconstruction.

Background: Irregularly shaped and three-dimensional soft-tissue defects in the extremities are difficult to cover precisely and efficiently. One strategy is to use the anterolateral thigh flap with two perforators and split the flap into two subunits based on separate perforators. The subunits can be rearranged into various geometric configurations to cover defects with nonelliptical shapes.
