Vanadurongwan V Using the implants for internal fixation of the proximal humeral fractures has several
problems which lead to complications and poor results of the fracture treatment. Because there
is no suitable implant for internal fixation of the fracture. Therefore, the reconstruction twisted
wire was developed in 1990 to improve the results of the fracture treatment. Between 1990 and
1994, the reconstruction twisted wire was used in 31 patients whose ages ranged from 18 to
90 years. Sixteen patients had displaced two-part surgical neck fractures. Fifteen patients had
displaced three-part fractures. Postoperative follow-up ranged from two and a half years to
five years and one month. All fractures healed. No avascular necrosis of the humeral head was
observed at the follow-up. There was temporary subluxation of the shoulder joint in three
patients and loosening of the screws in two patients with marked osteoporosis. One had a
rupture of wire between the greater tuberosity and the shaft and loosening of the screw at
the greater tuberosity and united with 10 degrees varus deformity. According to the functional
scale proposed by Hawkins, 28 of the 31 patients achieved a "good" result and 3 patients had
a "fair" result.
