If an open or closed extrinsic digital extensor tendon injury is present, there is no alternative to its surgical repair for preservation of motion in the metacarpophalangeal joint (MCPJ) II-V in particular in cases when arthrodeses both in the proximal interphalangeal joint (PIPJ) and distal interphalangeal joint (DIPJ) of the same long finger become necessary (Figures 4A-D)
For cases in which a extensor indicis proprius (EIP) tendon with 2 or more small tendon slips are found intraoperatively, the use of the extensor digitorum communis (EDC) index finger tendon which was found to be the most constant single tendon is recommended for transfer [98]
Summary
The rare injury of a closed digital extensor tendon avulsion of the third finger at its musculotendinous junction: Case presentation and brief overview of literature with regard to general, specific and practicable aspects to extensor tendon surgery involving tendon transfer procedures. Ultrasound revealed an avulsion injury at the musculotendinous junction (MTJ) of the left 3rd finger, and surgical revision by a tendon transfer procedure (TTP) utilizing the extensor indicis proprius (EIP) of the same hand was indicated and performed by us.
