Radiocarpal Joint Reconstruction with a Double Free Metatarsophalangeal Joint Transfer

Abstract

Background: Destruction of the radiocarpal and midcarpal joints causes loss of wrist motion, pain, and reduced grip strength. A novel technique for radiocarpal reconstruction is presented. Methods: Two patients who had radiocarpal and midcarpal destruction and osteoarthritis underwent reconstruction using simultaneous bilateral microvascular second metatarsophalangeal joint transfer. The insetting was performed, inverting the distal-proximal orientation of both metatarsophalangeal joints and fixing them with two 2.0 screws in proximal and Kirschner wires in distal. Results: Radiocarpal extension and flexion without pain were preserved after a minimum of 4 years follow-up. Both patients could return to recreational activities. No secondary procedures were needed. Conclusions: This technique could be an alternative for radiocarpal reconstruction, although longer follow-up and more cases are needed.

Cuboid Bone for Distal Radius Reconstruction: An Anatomical Cadaver Study

“…These investigations focused on ulnar head reconstructions using the second metatarsal. 26 27 28 Recently, Cavadas and Padial 29 reported a radiocarpal joint reconstruction with a double free metatarsophalangeal joint transfer with good results after 4 years of follow-up. To the authors' knowledge, this is the first study to consider radius reconstruction using the CB as a vascularized bone transfer.…”
