Which procedure is described as performed in zone 3 of the gastrosoleus complex?

• A. Z-lengthening tal
• B. Double/triple hemisection TAL
• C. Gastrosoleus recession
• D. Calcaneal osteotomy

Answer: (A)

In managing tightness of the gastrosoleus complex, lengthening the muscle-tendon unit is often needed to gain ankle dorsiflexion without compromising push-off. A Z-lengthening is a controlled soft-tissue lengthening performed within the gastrosoleus complex by creating a Z-shaped incision in the aponeurosis, allowing the unit to elongate. Zone 3 refers to the specific segment of the gastrosoleus where this Z-pattern lengthening is done, chosen to achieve the desired increase in length while preserving function. This makes the procedure described in zone 3 the best fit for the question. The other options involve lengthening or releasing different tissues: lengthening the Achilles tendon (TAL) or its partial hemisections, a broader gastrosoleus recession, or a calcaneal osteotomy (a bone realignment procedure).
