From August 1990 to December 2007, 156 patients with humeral shaft nonunion were treated with our patented Ni-Ti shape memory alloy swan-like memory pressure connector (SMC). The SMC device cooled with ice before implantation was warmed to 40-50 degrees C after implantation to produce balanced axial and compression forces to stabilise the fracture three-dimensionally. This combined with autologous bone grafting achieved bone tissue regeneration in the fracture and promoted smooth recovery of joint function, with a nonunion healing rate of 98.7% after a single SMC implantation. Failure of nonunion healing occurred in only two cases but was successfully managed by a further operation. Complications were not found in any of these patients apart from four with pre-existing radial nerve injuries. These results demonstrate the effectiveness of the SMC device for the management of humeral shaft nonunion. The device provides continuous compression of the fracture with minimal trauma to the local blood supply.

Background: Although the Neer and AO/OTA classifications have been widely accepted, observer reliability studies of these two classifications have questioned their reliability and reproducibility to date. We developed an entirely new classification, the Mitsuzawa classification, for dislocated and displaced proximal humeral fractures and tested all three classifications for their intra- and interobserver reliability.
Methods: Two experienced shoulder surgeons and two orthopedic residents independently evaluated the Xray (xR) values of 100 proximal humeral fractures (PHFs).

The upper end of the humerus consists of three necks such as anatomical neck, surgical neck and morphological neck. The anatomical neck of the humerus is the area just below the head of the humerus. The surgical neck of the humerus is the area just below the greater and lesser tubercle of the humerus.

Introduction: Antegrade intramedullary nail fixation for humeral shaft fractures yields satisfactory union rates. However, one of the related concerns is damage to the rotator cuff during nail insertion, which may affect long-term outcomes. The effect of a rotator cuff lesion on mid- and long-term shoulder outcomes remains unknown.
