From August 1997 to February 2000 we treated 16 clavicle fractures using the J plate and followed up on them for more than 4 months. The patients consisted of 10 males and 4 females with ages ranging from 15 to 80. According to the Robinson's classification method, all fractures were classified as Type 2 (1 case was Type 2A1, 3 cases were Type 2B1 and 10 cases were Type 2B2). We allowed 90 degrees abduction of the shoulder joint 4 weeks after the operation. All fractures achieved union, but union was delayed in 1 case. Plate failure occurred in 1 case, the bending of the J plate was seen 2 weeks after the operation and this deformation continued for 6 weeks. After the fracture achieved union, bending of the J plate stopped. We concluded that J plate is useful for midclavicle fractures.
