title: [Therapeutic results of the proximal humeral neck fractures].
abstract: Good therapeutic results can be obtained by conservative treatments for the proximal humeral neck fractures. However, surgical treatment is sometimes required in patients with 2- or 3-part fractures (Neer's classification) in whom the reduction of the fracture is unable to be maintained by conservative treatments. In this study, we performed the surgical treatment using anatomical bone plate on these patients and evaluated the therapeutic results. The materials consisted of twenty patients. The surgical procedure was performed plate fixation using anatomical bone plate by delto-pectral approach. The postoperative follow-up period ranged from one year to eight years and six months (mean;three years and two months). No patient showed ununited fracture site or humeral head necrosis. The average range of motion in the shoulder was 172 degrees in elevation, 164 degrees in abduction, and ninth thoracic level in internal rotation. Favorable therapeutic results can be obtained by plate fixation using anatomical bone plate in patients with 2- or 3-part fracture of the proximal humeral neck. However, there is necessary in consideration to treat using anatomical plate in patients with severe osteoporosis.
