There were some patients who had humeral head perforations after operation for proximal humeral fracture using an All-in-One Nail. The purpose of this study was to investigate the rate of perforation, the cause of perforation and the influence of perforation on the postoperative outcome. We evaluated the clinical result of 12 patients who underwent internal fixation with All-in-One Nails for proximal humeral fracture. 1. Number of humeral head perforations after surgery, 2. number of perforations during operating, 3.redisplacement after surgery, 4. the starting day of exercises after surgery, 5. active ROM at the latest examination (flexion, abduction) were examined. 3 cases had perforation after surgery. 2 cases of perforated group had perforation during surgery. Redisplacement after surgery was seen equally in both groups. The starting day of exercises tended to be earlier in perforated group. The mean ROM tended to be larger in not perforated group. Some advantages of the All-in-One Nail were described, such as low invasive, maintains alignment to the distress cases and it could start exercises at an early period. On the other hand, from our study, the risk factors of humeral head perforation was clarified as perforation during surgery and starting exercises at an early period after surgery. All-in-One Nail gives support to fracture that cannot keep the reposition during conservative treatment, but does not have enough stability immediately after operation among the other implants.
