Distraction osteogenesis of fourth brachymetatarsia

Area of Science:

• Orthopedic surgery
• Podiatric medicine
• Congenital conditions

Background:

• Brachymetatarsia is a rare condition causing a short metatarsal, often the fourth.
• Primarily affects young females, presenting cosmetic rather than functional issues.
• Adult cases of brachymetatarsia require effective treatment strategies.

Purpose of the Study:

• To evaluate gradual distraction of the fourth metatarsal for treating adult brachymetatarsia.
• To assess the efficacy and patient satisfaction with this lengthening technique.

Main Methods:

• Gradual distraction using a monolateral frame in 11 adult female feet.
• Average patient age was 23 years.
• Outcomes measured by achieved length, angulation, pain, and patient satisfaction.

Main Results:

• Achieved eight excellent and three good outcomes.
• Average follow-up was 2.6 years.
• Minor complications included nine cases of mild pin-tract infection.

Conclusions:

• Distraction osteogenesis is recommended for treating brachymetatarsia of the fourth toe.
• The technique offers a viable solution for cosmetic concerns associated with short metatarsals.
