The authors report their experience with closed reduction and percutaneous pinning of twenty-two supracondylar fractures of the humerus in children. In cases with neurovascular complications there was a marked regression within six hours following reduction. The results after 15 months to 13 years were satisfactory (excellent + good) in 90% of the cases, avoiding the risks and possible cicatricial complications of incisions and the discomfort of orthopaedic treatment in traction and subsequent thoracic-brachial plaster cast.
