Proximal Phalanx and Flexor Digitorum Longus Tendon Biomechanics in Flexor to Extensor Tendon Transfer

Abstract

Iatrogenic fracture may occur in proximal phalanges with a diameter of bone less than 6 mm, as there may not be adequate bone strength remaining to withstand postoperative forces.

Clinical and Radiographic Results of a Dual-Component Intramedullary Implant for Hammer Toe Deformity in Patients with Rheumatoid Arthritis

“…Surgical procedures for hammer toes include flexor digitorum longus tendon transfer [4], shortening osteotomy of the proximal phalanx neck [5], PIP joint arthrodesis [6], and metatarsal shortening osteotomy [7]. Fixation methods for the PIP joint include K-wire or headless screw insertion through the distal phalanx and insertion of an intramedullary implant, either a single-device type or a dual-component type implant.…”
