Surgical Techniques

First Metatarsal Hemiepiphysiodesis

Minimally invasive technique using residual growth. A small plate (eight-plate) is placed on the growth plate of the first metatarsal to progressively correct the deviation angle.

Indication

Juvenile hallux valgus in children with sufficient residual growth. Preferred when age allows as it is less invasive.

Recovery

Full weight bearing after a few days. Correction occurs gradually over months. Plate removal once correction achieved.

Distal Metatarsal Osteotomy

Procedure involving cutting and realigning the first metatarsal head to correct the deviation angle. Specific technique chosen based on deformity severity.

Indication

Symptomatic juvenile hallux valgus at end of growth or not responding to conservative treatment, with pain or footwear difficulties.

Recovery

Post-operative shoe for 4-6 weeks. Gradual return to walking. Sports after 3-4 months.

Soft Tissue Procedures

Capsular release and tendon rebalancing procedures to correct muscle imbalance contributing to deformity.

Indication

Mild-moderate forms, often combined with osteotomy.

Recovery

Faster recovery than isolated osteotomies, but requires specific physical therapy.

Postoperative Overview

Each surgery is individually planned. The timeline below is a general baseline that varies significantly depending on the surgical technique chosen. For hemiepiphysiodesis recovery is much faster. Complete recovery typically requires 3-4 months for osteotomies. Regular follow-up is important to evaluate correction stability during residual growth.

Detailed Recovery Timeline

Note: The timeline below is a general baseline. The actual postoperative course varies depending on the specific surgical technique chosen (see procedures above).

Day-surgery in most cases. Discharge with rigid-soled post-operative shoe (for osteotomy) or free walking (for hemiepiphysiodesis).

Osteotomy: walking with talus shoe (offloading forefoot). Rest with elevated foot. Weekly dressing changes. Hemiepiphysiodesis: full weight bearing after a few days.

Osteotomy: suture removal at 14-18 days. Control X-ray. Gradual transition to soft footwear. Hemiepiphysiodesis: normal life, correction occurs gradually.

Osteotomy: normal walking resumed. Physical therapy for joint mobilization and strengthening. Hemiepiphysiodesis: X-ray checks to monitor correction.

Return to Sport

Osteotomy: return to sport 3-4 months. Hemiepiphysiodesis: sports after 4-6 weeks. Wide-toe shoes for at least 6 months.

Follow-up Schedule

Follow-ups at 2 weeks, 6 weeks, 3 months, 6 months, 1 year. Then during residual growth. For hemiepiphysiodesis: checks every 3-4 months until plate removal.

Possible Complications

Possible: recurrence during growth (that's why we prefer operating at end of growth or using hemiepiphysiodesis), metatarsophalangeal stiffness, transfer metatarsalgia.
