The V in a V-Y tendon lengthening should correspond to what multiple of the advancement length?

The V in a V-Y tendon lengthening should correspond to what multiple of the advancement length?

• A. 0.5x
• B. 1x
• C. 2x
• D. 1.5x

Answer: (D)

In V-Y tendon lengthening, the V incision is designed so that when you advance the tendon and convert the V into a Y, the overall length gain matches the target. The V should be about one and a half times the advancement length. This 1.5x relationship accounts for the tissue rearrangement and the way the two limbs of the V spread apart to form the Y, giving the necessary lengthening without overdoing it. If the V is only the same as the advancement, you’d end up under-lengthening; if it’s much larger (near double), you risk over-lengthening and weakness. The 1.5x rule provides a safe, effective balance for achieving the desired tendon length.
