Baker gastrocnemius recession

What it is

The gastrocnemius is the larger, more superficial of the two calf muscles. When it is too tight it tethers the ankle in an equinus (“tiptoe”) position so the heel can’t reach the floor. A gastrocnemius recession lengthens the muscle–tendon unit so the foot can sit flat (plantigrade). The Baker technique is one classic “tongue-in-groove” way of doing this at the muscle–tendon junction; closely related named techniques include the Strayer, Vulpius, and Baumann recessions. Because it lengthens only the gastrocnemius and spares the deeper soleus, it preserves more push-off strength than a full Achilles (heel-cord) lengthening.

Why it's done

• Persistent idiopathic (habitual) toe walking that has not resolved with stretching, therapy, casting, or bracing — once a fixed calf contracture has actually developed
• Equinus contracture in cerebral palsy or other neuromuscular conditions
• A tight gastrocnemius confirmed on the Silfverskiöld test (the ankle can’t dorsiflex past neutral with the knee straight, but improves with the knee bent)
• Reminder: most toe walkers never need surgery — it is considered only after conservative care fails and a true fixed contracture is present, usually in older children

How it works

Performed under anesthesia through a small incision at the back of the calf. The surgeon divides the gastrocnemius aponeurosis (its broad tendon sheet) so the muscle slides to a longer resting length, brings the foot up to neutral, and closes the wound. It is commonly followed by a short-leg cast or walking boot for a few weeks.

What to expect

Typically a cast or boot for a few weeks, then physical therapy to rebuild calf strength and retrain a normal heel-to-toe walking pattern. Most children return to full activity within a few months. The goal is a stable, flat (plantigrade) foot and a heel-strike gait.

Risks & side effects

• Over-correction or under-correction (too much or too little lengthening)
• Temporary calf weakness during recovery
• Recurrence of tightness — more likely in younger children who are still growing
• Wound healing problems, scar, or (uncommonly) sural-nerve irritation
• General anesthesia and standard surgical risks
