PERCUTANEOUS FIXATION OF PROXIMAL HUMERAL FRACTURES

Two-part surgical neck fractures, two-part greater tuberosity fractures and three- and four-part fractures of the proximal humerus represent a frequently encountered clinical problem. Many types of conservative treatments have been proposed, with a poor functional outcome, however; when the fracture fragments are displaced, surgery is required.Because the open reduction and the internal fixation disrupts soft tissue and increases the risk of avascular necrosis of the humeral head, closed or minimally open reduction and percutaneous pin fixation should represent an advantage.We report on 31 patients affected by fractures of the proximal humerus (n=6, two-part surgical neck fractures; n=5, with two-part greater tuberosity fractures; n=10, three-part fractures; and n=11, four- part fractures) treated with minimally open reduction and percutaneous fixation. The average age was 57 years. Most of the four-part fractures were of the valgus type with no significant lateral displacement of the articular segment. A...
