TREATMENT OF 3-PART AND 4-PART FRACTURES OF THE PROXIMAL HUMERUS WITHA MODIFIED CLOVERLEAF PLATE

Twenty-six patients, ranging in age from 19 to 62 years (average 55), were evaluated an average of 6 years and 2 months (range 1-12 years) a fter open reduction and internal fixation of a three- or four-part fra cture of the proximal humerus using a modified cloverleaf plate. Six p atients had an associated dislocation of the humeral head. All fractur es healed. No avascular necrosis of the humeral head was observed at f ollow-up. Twenty-two patients had an excellent result, two a good resu lt, and two a fair result. The modified cloverleaf plate proved to be an excellent method for the treatment of proximal humerus fractures. O pen reduction and internal fixation of three- and four-part fractures of the proximal humerus should be considered as initial treatment by a n experienced surgeon, even before use of a prosthetic replacement, wh ich is recommended only for elderly patients with osteopenia.
