title: [T-plate osteosynthesis in dislocated proximal humerus fractures].
abstract: From 1988 through 1995 we operated 48 patients with dislocated humeral fractures using the T-Plate (median age 66 years [20 to 90 years], 32 male, 16 female). After a median 22 months (9 to 60 months) 33 patients were followed up clinically and radiologically. Six patients had suffered a 2-part fracture, 17 a 3-part fracture, and 10 a 4-part fracture. Judged by the Constant score 6 patients reached a very good result, 8 had a good result, 4 a satisfactory and 15 a poor result. Radiologically we saw an arthrosis in 31%, an axial deviation in 50%, and a dislocation of the fragments in 72%. The rate of necrosis of the humeral head was 39%. MRI (17 patients) provided additional relevant information about soft tissue and bone quality and is valuable in the early detection of necrosis of the humeral head. Functionally poor results correlated rather to dislocated fragments and persisting axial deviation than to the type of fracture or the necrosis of the humeral head. The T-plate osteosynthesis is one way to treat dislocated fractures of the proximal humerus, if early operation, correct reposition, and biological principles are respected.
